Top 7 Office Fit Out Companies UK For Tech-Ready Workplaces In 2026

Choosing the right partner from the many office fit out companies UK has to offer is no longer just about aesthetics and furniture. A modern office is a complex ecosystem of technology, connectivity, and power. The foundation of every productive, secure, and future-proof workplace is its digital infrastructure. From structured cabling and robust Wi-Fi to server room integrity and integrated AV systems, getting the technical design right from day one is critical. This guide profiles seven leading UK fit-out firms and provides an essential checklist for evaluating their technical capabilities, ensuring your new workspace is built for performance from the ground up.

The selection process can be daunting. Your choice of partner determines not only the look and feel of your space but also its operational reliability. A poorly planned network can cripple productivity, while a well-executed IT infrastructure becomes an invisible asset that supports every business function. When selecting a fit-out partner, consider their expertise in creating innovative office layouts that support hybrid work and productivity, a crucial element for modern workplaces.

This article cuts through the noise. We will provide a detailed look at each company, complete with screenshots and direct links, focusing on their service offerings in critical areas like structured cabling, commercial electrical installation, CCTV, and server room construction. We will also delve into more advanced topics, such as the practicalities of creating fully autonomous unmanned building units and why the integration of access, power, and data systems is essential for success. This roundup is designed for IT managers, operations leaders, and anyone tasked with delivering a technically sound office fit-out or relocation project.

1. Overbury

Overbury stands as one of the most established and largest specialist office fit-out companies in the UK, backed by the considerable resources and financial stability of its parent company, Morgan Sindall Group. The firm is renowned for delivering large-scale, complex projects across the country, from corporate headquarters for global brands to highly specialised environments in higher education and life sciences. Their website serves as an extensive portfolio, showcasing a vast library of case studies that provide deep insight into their capabilities.

For IT and operations managers, Overbury’s value lies in its structured, process-driven approach to project delivery. They have a proven track record of handling intricate technology integrations within their fit-outs, although clients often need to ensure their own IT specialists or partners are deeply involved to specify the granular details of network infrastructure, from structured cabling to server room construction. Their nationwide presence, with regional offices in key cities, makes them a strong candidate for multi-site rollouts where consistency and robust governance are critical.

Key Service Offerings

Overbury's core services are geared towards significant capital projects. They excel in both traditional and design-and-build procurement routes, providing end-to-end management.

• Category A & Category B Fit-Out: Full-service delivery, from preparing a building for tenant fit-out (Cat A) to creating a complete, ready-to-occupy workspace tailored to a client's specific operational needs (Cat B).

• Refurbishment: Modernising existing workspaces to improve functionality, sustainability, and employee well-being.

• Specialist Sectors: Deep experience in delivering technically demanding projects for universities, laboratories, and secure corporate environments.

Why Overbury Stands Out

Their scale is their primary differentiator. For enterprise-level clients, particularly those with complex stakeholder management and stringent compliance requirements (like NHS or financial services), Overbury’s formalised project management methodologies provide a level of assurance that smaller firms may struggle to match. Their supply chain is robust and well-vetted, reducing risk on time-critical schemes. The sheer volume of projects they complete offers a wealth of lessons-learned, which can be invaluable for large, intricate builds. Managing a project of this scale requires careful planning, a topic further explored in our practical guide to office fit-out project management.

Website: https://www.overbury.com/

Pros	Cons
Proven delivery on high-value, complex projects.	May be less suited to very small or agile, fast-turnaround works.
Strong governance and financial backing from Morgan Sindall Group.	Enterprise processes can sometimes feel less flexible for boutique needs.
Extensive best-practice knowledge from a large portfolio.	Typically targets mid-to-large project budgets.
Nationwide UK coverage with established regional offices.

2. Morgan Lovell

A sister company to Overbury within the Morgan Sindall Group, Morgan Lovell operates as a specialist design-and-build firm with a strong focus on London and the South of England. The company has carved out a reputation for creating award-winning, people-centric workspaces that blend aesthetics with functionality. Their approach is heavily geared towards an integrated process, combining workplace consultancy, design, and project management into a single, cohesive service for clients in sectors like finance, technology, and professional services.

For IT and facilities managers, Morgan Lovell’s structured delivery methodology, named ‘Perfect Delivery’, is a key attraction. This framework is designed to ensure projects are completed on time, on budget, and free of defects, which is critical when coordinating complex technical installations. Their design-led process means that technology infrastructure, from AV systems to comms room requirements, is considered early in the planning phase. This integrated approach helps prevent the common issue where essential IT elements like power, data, and access control are not designed in a unified way, a critical step detailed in our ultimate office fit-out checklist.

Key Service Offerings

Morgan Lovell’s services cover the entire project lifecycle, from initial strategy to post-completion support, making them one of the leading design-and-build office fit out companies in the UK for their region.

• Design & Build: An end-to-end solution that combines workplace strategy, interior design, and construction under a single point of responsibility.

• Workplace Consultancy: In-depth analysis of a company's culture, work patterns, and future goals to inform the design brief and space planning.

• Fit-Out & Refurbishment: Delivering both Cat A and Cat B fit-outs, with a particular strength in transforming spaces for major headquarters and landlord projects.

Why Morgan Lovell Stands Out

Their 'Perfect Delivery' promise and high client satisfaction scores set them apart. This structured methodology provides a clear roadmap and governance structure that gives clients, especially those with tight deadlines for HQ relocations, a high degree of confidence. While backed by the financial strength of a FTSE-250 parent company, their regional focus on London and the South allows for deep market knowledge and a highly curated local supply chain. This combination of robust processes and regional expertise makes them a formidable partner for ambitious projects within their geographic area.

Website: https://www.morganlovell.co.uk/

Pros	Cons
High client satisfaction driven by a structured delivery approach.	Geographic concentration in London/South may limit UK-wide rollouts.
Strong award recognition and deep regional expertise.	Enterprise frameworks can extend pre-construction stages for smaller projects.
Integrated design-and-build model simplifies project management.	Design-led focus may not suit clients with a pre-appointed design team.
Backed by Morgan Sindall Group for financial resilience.

3. Oktra

Oktra is a prominent London-headquartered design and build practice known for creating experience-led, high-impact office environments. With a strong focus on brand integration and workplace culture, they have carved out a reputation for delivering agile and aesthetically refined fit-outs. As a Certified B Corporation, Oktra places sustainability and strong ESG governance at the core of its design philosophy, appealing to clients who prioritise ethical and environmental considerations alongside commercial objectives. Their website showcases a portfolio rich with projects for fast-moving tech firms, established corporate clients, and flexible workspace providers.

For IT and Facilities Managers, Oktra's value proposition is its end-to-end service model, which incorporates in-house workplace consultancy from the outset. This ensures that technology and operational needs are considered early in the design phase, rather than as an afterthought. Their ability to scale from small works and refurbishments to large, multi-floor headquarters makes them a versatile partner. While they have a strong in-house design capability, their model requires close collaboration with a client’s IT team or a specialist partner to translate high-level tech requirements into detailed specifications for network infrastructure and specialist systems.

Key Service Offerings

Oktra’s services are built around a seamless design and build process, designed to reduce complexity and accelerate project delivery. They are a go-to choice for clients seeking a single point of responsibility.

• End-to-End Design & Build: A fully integrated service covering strategy, design, and construction, simplifying procurement and ensuring design intent is perfectly executed.

• Office Fit-Out & Refurbishment: From full Category B fit-outs for new tenants to phased refurbishments in occupied buildings, they manage the entire construction process.

• Workplace Consultancy: In-house expertise to help clients define their future ways of working, ensuring the physical space aligns with business goals and employee needs.

• Furniture Procurement: A dedicated team to specify, source, and install furniture that complements the design and supports functionality.

Why Oktra Stands Out

Oktra’s key strength lies in its design-centric, agile delivery model. They excel at translating a company's brand and culture into a physical environment, which is particularly valuable for client-facing spaces or businesses competing for top talent. Their B Corp certification provides tangible proof of their commitment to sustainability, a critical factor for many organisations' procurement criteria. While their expertise is concentrated in London, their methodology is well-suited to the fast pace of city-centre projects. The design-led approach means that the foundations for a robust tech infrastructure, such as the specifics of your data cabling installation plan, must be clearly defined and integrated early to align with the aesthetic and functional vision.

Website: https://www.oktra.co.uk/

Pros	Cons
Agile delivery ideal for fast-paced city-centre projects.	London-centric focus may require travel or partnerships for remote UK regions.
Strong design aesthetic and brand/experience integration.	Premium design approach may increase costs for purely functional briefs.
Certified B Corporation with a clear focus on ESG.	Design-led process requires clients to have clear tech specs early on.
Scales from small works to large multi-floor headquarters.

4. Peldon Rose

Peldon Rose is a prominent design and build firm with a strong reputation for creating people-centric workplaces, primarily within London and the South East. They offer an end-to-end service that begins with workplace strategy and extends through design, construction, and crucially, long-term aftercare. Their portfolio is particularly strong in the tech, media, finance, and consumer brand sectors, showcasing spaces that are as functional as they are aesthetically engaging. The company's emphasis on building lasting relationships with clients through post-occupancy support makes them a compelling choice.

From an IT manager's perspective, Peldon Rose’s integrated design and build model provides a single point of accountability, which can simplify the complex process of coordinating technology and construction. Their focus on aftercare is a key advantage, offering a framework for ongoing adjustments to AV systems, network points, or access control as business needs evolve. This lifecycle approach is beneficial for dynamic companies where office layouts and technology requirements may change post-move, ensuring the workspace remains fit for purpose long after the initial project is complete.

Key Service Offerings

Peldon Rose's services are structured to provide a seamless journey from initial concept to a fully operational and maintained workspace. Their integrated team handles all aspects of the project under one roof.

• Workplace Strategy & Design: In-depth consultancy to define how a space can best support a company's culture, workflow, and business goals before design begins.

• Design & Build Fit-Out: A unified project delivery model covering all stages from design and specification to construction and handover, ensuring speed and clear communication.

• Furniture Consultancy & Procurement: Specialist advice and sourcing of furniture that aligns with the design intent, ergonomic needs, and budget.

• Aftercare & Maintenance: Ongoing support services post-completion, covering everything from minor repairs to small-scale reconfigurations and technology adjustments.

Why Peldon Rose Stands Out

The firm’s dedication to post-occupancy support and client relationships is a significant differentiator. While many fit-out companies focus purely on project delivery, Peldon Rose’s "for life" ethos means they remain a partner, ready to assist with the ongoing evolution of the workspace. This is particularly valuable for IT and operations teams who manage the constant need for changes to data cabling, AV equipment, and power layouts. Their cohesive, single-team approach promotes speed and accountability, which is a major benefit for projects on tight timelines in the competitive London market.

Website: https://www.peldonrose.com/

Pros	Cons

Operating across the UK and Europe, the company has built a reputation over 25 years for delivering high-quality office design, fit-out, and refurbishment projects. Their website showcases a diverse portfolio, with a clear emphasis on the technology, life sciences, and corporate sectors, appealing to businesses where ESG (Environmental, Social, and Governance) values are a core part of their identity.

For IT and operations leaders, Area's experience in tech-forward environments is a significant draw. They understand that for modern businesses, particularly in life sciences and technology, the physical workspace is inseparable from its digital infrastructure. Their case studies demonstrate an ability to integrate robust network, Wi-Fi, and structured cabling solutions into complex designs, including specialised laboratory settings. This integrated approach, which combines workplace consultancy with construction and furniture supply, ensures that technology requirements are considered from the initial design phase, not as an afterthought. Their European delivery capability also makes them a strong partner for international organisations seeking a consistent workspace experience across multiple countries.

Key Service Offerings

Area provides a holistic service that covers the entire project lifecycle, from initial strategy to post-occupancy support. Their B Corp certification underpins a commitment to sustainable and ethical practices throughout their delivery process.

• Design & Build: An end-to-end service combining workplace consultancy, design, cost management, and construction into a single, seamless process.

• Workplace Consultancy: Strategic services to help clients define their workplace needs, optimise space, and align their physical environment with business goals.

• European Delivery: Specialised capability to manage and deliver fit-out projects for clients with a portfolio of offices across the UK and mainland Europe.

• Specialist Sectors: Proven experience in technically demanding environments such as technology hubs, R&D facilities, and life science laboratories.

Why Area Stands Out

Area’s B Corp status is a key differentiator, appealing strongly to clients with robust sustainability and corporate responsibility targets. This isn't just a badge; it reflects a deep-seated commitment to ethical supply chains, reduced environmental impact, and employee well-being that is woven into their project delivery. For an IT manager planning a new facility, this translates into confidence that aspects like power efficiency and the responsible disposal of old equipment will be handled correctly. Their ability to deliver projects on an international scale provides a single point of contact for businesses standardising their workplace technology and design across borders, simplifying what can be a highly complex logistical challenge.

Website: https://area.co.uk/

Pros	Cons
Strong science/tech credentials and ESG alignment via B Corp status.	For very small works, lead times may be longer than boutique firms.
Scales from mid-size to large projects with cross-border reach.	European scope can add overhead for purely local, low-complexity jobs.
Integrated service from consultancy through to furniture and aftercare.
Experience in delivering technically complex workspaces like labs.

6. BW: Workplace Experts

BW: Workplace Experts has carved out a strong reputation in the UK office fit out market, particularly for its disciplined approach to project delivery and a public commitment to defect-free handovers. They specialise in complex refurbishments within occupied buildings, where minimising disruption and maintaining business-as-usual for the client are paramount. Their website showcases a portfolio heavily geared towards creating high-quality, professional environments, backed by a clear methodology focused on stakeholder communication and operational continuity.

For IT and operations managers, BW’s expertise in live environments is a significant benefit. Staged refurbishments require meticulous planning of IT infrastructure, from temporary network setups to phased migrations of server equipment and structured cabling. BW's process-driven approach is well-suited to these scenarios, ensuring that critical systems remain online. Their public commitment to achieving Net Zero by 2030 also means they are adept at specifying energy-efficient electrical systems and sustainable M&E (Mechanical & Electrical) solutions, a key consideration for modern server room design and power management.

Key Service Offerings

BW offers a complete suite of services, with a notable specialism in handling the logistical challenges of working in active, operational buildings.

• Refurbishment-in-Occupation: A core specialism involving phased project delivery to allow clients to continue their operations with minimal disruption.

• Category A & B Fit-Out: Full-scope fit-out services, from preparing a landlord's shell (Cat A) to delivering a fully bespoke, tenant-ready workspace (Cat B).

• Design & Build: An integrated approach offering a single point of accountability for both the design and construction phases of a project.

• Sustainability Focus: Incorporating their Net Zero goals into project delivery, focusing on sustainable materials and energy-efficient systems.

Why BW Stands Out

Their commitment to a "Defect Free" handover is a key differentiator. This focus on quality control and snagging throughout the project, rather than just at the end, provides a higher degree of certainty for clients, especially around the commissioning of critical IT and building systems. This disciplined process is particularly valuable in complex refurbishments where new infrastructure must integrate seamlessly with existing building services. Their experience in live environments gives them a practical understanding of how to manage noisy works, control dust, and coordinate services to protect sensitive IT equipment during construction.

Website: https://wearebw.com/

Pros	Cons
Reputation for high-quality finishes and defect-free delivery.	Project history is predominantly London-centric; may add logistics elsewhere.
Deep experience in minimising disruption during live operations.	Formal processes can add lead-in time for smaller, fast-paced projects.
Strong, publicly stated commitments to sustainability and inclusivity.
Well-defined processes for stakeholder communication and project management.

7. TSK

TSK operates at the intersection of workplace strategy, design, and build, establishing itself as a prominent UK firm with a research-led approach. With studios in Manchester and London, they deliver projects nationwide, focusing on human-centric designs that support hybrid working, employee wellbeing, and sustainability. Their website acts as a resource hub, featuring detailed case studies and insightful "playbooks" that articulate their data-informed philosophy. TSK’s status as a Certified B Corporation underscores its commitment to responsible business practices and a sustainable supply chain.

For operations and IT managers, TSK’s integrated model is a key advantage. By handling strategy, design, and construction in-house, they ensure that critical infrastructure needs are considered from the outset, not as an afterthought. Their experience is particularly relevant for businesses undergoing significant organisational change or adopting new work models. The firm is adept at planning phased project delivery for UK-wide portfolios, ensuring consistency while accommodating regional nuances. This is especially useful for complex rollouts that require careful coordination of data, power, and access control systems to support modern, flexible work environments.

Key Service Offerings

TSK’s services are built around a holistic process, from initial strategy to post-occupancy support, making them one of the more comprehensive office fit out companies in the UK.

• Workplace Strategy & Consulting: Data-driven analysis to define how a client's space can best support their business objectives, culture, and new ways of working.

• Design & Build: An end-to-end service combining creative design with construction management, offering a single point of accountability for the entire project lifecycle.

• Furniture, Fixtures & Equipment (FF&E): Sourcing and management of all furniture and equipment, with a focus on ergonomics, sustainability, and aesthetics.

• Change Management: Supporting teams through the transition to a new workspace to maximise adoption and ensure the project's long-term success.

Why TSK Stands Out

Their B Corp certification and strong emphasis on measurable outcomes set them apart. TSK doesn’t just build offices; they aim to create high-performing workplace environments that positively impact people, the planet, and profit. This research-led methodology is appealing to organisations looking for a strategic partner rather than just a contractor. Their balance of a strong presence in the North of England combined with their London studio provides genuine nationwide reach, making them a solid choice for companies with a distributed UK footprint.

Website: https://www.tskgroup.co.uk/

Pros	Cons
Strong emphasis on wellbeing, hybrid work, and measurable outcomes.	Lead times can be longer if extensive workplace strategy is required.
Balanced London-regions coverage, ideal for UK-wide portfolios.	More of a boutique firm compared to the largest national contractors.
B Corp certification demonstrates commitment to sustainability.	May not be the primary choice for purely construction-led projects.
Integrated strategy, design, and delivery model.

Building the Autonomous Workplace: A Specialist Approach

Choosing the right partner from the many capable office fit out companies UK has to offer is a significant decision. As we've explored, firms like Overbury, Morgan Lovell, and Oktra deliver exceptional aesthetic and functional design. They create environments where people want to work, focusing on space planning, furniture, and finishes that define a company's culture. For many traditional office refurbishment projects, their expertise is exactly what is needed to achieve a brilliant outcome.

However, a new frontier is emerging: building out fully autonomous unmanned building units. This demands a technology-first perspective that goes beyond conventional fit-out practices.

What Unmanned Building Management Means in Practice

In practical terms, an unmanned building is a space—be it a single storage unit, a data centre, or a network of remote depots—that can operate securely and reliably without daily human intervention. It relies on a seamlessly integrated digital infrastructure for access, security, and environmental control. This is common in sectors like self-storage, logistics, remote 'dark' kitchens, and decentralised data management facilities where staff are not permanently on-site.

Why Many Unmanned Building Projects Fail

Many projects fail because they treat technology as an add-on rather than the foundation. The classic mistake is having separate contractors for electrical, data, and security systems who work from different plans. This fragmented approach leads to systemic weaknesses:

• Siloed Design: A network outage takes down the IP-based CCTV and access control. A localised power trip disables the entire security system.

• Cascading Failures: Without a unified design, there's no single point of accountability. The electrical contractor blames the data installer, who blames the security company, leaving the client with an insecure, inoperable unit.

How Access, Power, and Data Must Be Designed Together

For an unmanned unit to be truly resilient, its core systems must be designed as one interdependent ecosystem. Access, power, and data are not separate disciplines; they are three pillars of a single operational foundation. The process starts with a certified commercial electrical installation that anticipates the needs of the network and security hardware, including robust surge protection and backup power. The structured data cabling is then routed to support cameras, sensors, and access points, ensuring a cohesive flow of information and control. This unified approach prevents the single points of failure that plague siloed projects.

The Case for Battery-less, NFC Proximity Locks

A key real-world decision in unmanned design is the choice of access control. Battery-powered locks are a common source of failure and a huge operational burden. Real-world reasons for choosing battery-less, NFC proximity locks are compelling:

• Zero Maintenance: They draw power from the user's NFC-enabled device (like a smartphone), eliminating the recurring cost and labour of replacing hundreds of batteries across multiple sites.

• Enhanced Reliability: No battery means no risk of a lock failing due to a dead power source, a critical vulnerability in an unmanned environment.

• Simplified Management: Access credentials can be managed and revoked remotely, providing secure, auditable entry without physical key management.

Maintenance and Operational Considerations

A successful unmanned building is designed for minimal long-term intervention. This means specifying rugged, remotely manageable hardware for everything from CCTV to network switches. The entire system—from the server room build-out to the final camera placement—must be engineered for resilience and low-touch operation. This approach significantly reduces the total cost of ownership and ensures the facility remains secure and functional long after the fit-out is complete.
