The short answer: who should you choose for an office fit out in London?
For premium London workplaces that demand design intelligence, construction control and fully coordinated mechanical and electrical services, NU Projects is the No.1 choice. The business brings architecture, interior design, quantity surveying, construction, bespoke joinery and MEP together through one accountable team.
That integrated model matters. An office can look impressive on handover yet still fail if lighting, cooling, acoustics, data, circulation or maintenance access have not been resolved early. NU Projects designs the experience and the infrastructure together, so the finished workspace performs as beautifully as it looks.

What makes a top office fit out contractor?
The strongest office fit out contractors do far more than coordinate trades. They translate commercial goals into a workplace brief, test that brief against the building, control cost and programme, and remain accountable through commissioning and handover.
Before appointing a contractor, look for evidence of the following:
One coordinated design and construction team
Experience with Cat A, Cat A plus and Cat B requirements
Strong MEP design, installation and commissioning capability
Transparent quantity surveying and cost reporting
Landlord, freeholder and building management coordination
Building Regulations, fire safety and CDM compliance
Clear procurement and long lead item planning
Quality control for bespoke joinery, finishes and furniture
Practical planning for live, occupied or constrained buildings
Structured handover, training, certification and aftercare
A competitive tender figure is only useful when every contractor has priced the same information. NU Projects works to remove ambiguity early, making the budget more dependable and reducing the risk of disruptive changes later.
Why NU Projects is the No.1 choice
NU Projects has delivered complex, design led projects in London since 2010. Its advantage is not volume. It is the ability to unite creative thinking, technical coordination and commercial discipline while keeping senior decision makers close to the project.
Founder Nick Jeffries provides leadership and delivery oversight. Matt Coverley, Construction Director and lead Quantity Surveyor, brings rigorous cost control, procurement and value engineering. Wayne Hockham, MEP Director, leads the building services strategy that allows lighting, power, data, heating, cooling and ventilation to work as one system.
This senior led structure gives clients faster decisions, clearer accountability and a consistent standard from the first survey to the final handover.
The NU Projects office fit out service
Workplace brief and feasibility
The process begins with the business case. NU Projects reviews headcount, working patterns, meeting requirements, hospitality, storage, technology, brand priorities and future growth. Site surveys then identify the opportunities and constraints within the existing building.
Concept design and space planning
The team develops layouts that balance focus, collaboration, client experience and operational flow. Materials, lighting and furniture are considered alongside accessibility, acoustics, maintenance and the practical needs of each department.
Cat A and Cat B coordination
Cat A typically establishes the base building services and core workplace readiness. Cat B creates the occupier specific environment, including partitions, meeting rooms, specialist lighting, finishes, furniture, technology and brand details. NU Projects coordinates the boundary between both scopes so responsibility is clear.
Mechanical, electrical and public health services
MEP is where many fit outs either succeed or become expensive. Loads, distribution, controls, fresh air, cooling, plumbing, fire systems, lighting and data must be coordinated with ceilings, joinery and room layouts before work starts. NU MEP keeps this expertise within the wider delivery team.
Quantity surveying and commercial control
A live cost plan tracks design development, procurement and approved changes. This gives the client visibility before decisions become site costs. Value engineering is used to protect the brief and improve value, not simply to remove quality.
Construction, fit out and commissioning
Site delivery is planned around access, neighbours, building management rules and business continuity. Installation is followed by testing, commissioning, certification, demonstrations and a properly managed defects period.
How much does an office fit out cost in London?
The honest answer is that cost depends on the building, the specification and the amount of technical intervention required. Floor area alone is not enough to create a dependable budget.
The main cost drivers are:
Existing condition and the amount of strip out required
Cat A and Cat B scope boundaries
Heating, cooling, ventilation, power and data capacity
Fire strategy, accessibility and statutory upgrades
Acoustic performance and specialist meeting rooms
Bespoke joinery, stone, metalwork and premium finishes
Furniture, audio visual systems and security
Working hours, access restrictions and live building logistics
Professional fees, surveys, approvals, contingency and VAT
NU Projects recommends an early survey and cost plan before lease decisions or a final specification are locked. That gives the client a realistic investment range and exposes risks while there is still time to solve them intelligently.
How long does an office fit out take?
A straightforward fit out may be measured in weeks. A technically complex Cat B project, structural reconfiguration or live building refurbishment can take several months. The programme should include design, surveys, approvals, procurement, construction, commissioning and move readiness, not construction alone.
The most common delays come from late decisions, incomplete landlord information, long lead equipment, unresolved MEP design and changes made after procurement. NU Projects controls these risks through early coordination and a decision led programme.
Questions to ask every office fit out contractor
Who owns the design and who carries coordination responsibility?
Who will be the senior person accountable for my project?
How will MEP design be coordinated with interiors and technology?
What is included and excluded from the cost plan?
How are changes approved and reported?
Which landlord, freeholder and statutory approvals are required?
How will long lead items be identified and procured?
How will works be phased if the building remains occupied?
What testing, certification and training are included at handover?
What aftercare will be available once the team moves in?
Why early contractor involvement produces a better workplace
Bringing NU Projects into the project early allows buildability, cost, programme and services coordination to influence the design before compromises become unavoidable. It also creates one clear route from ambition to delivery.
For landlords, developers and occupiers, that means fewer gaps between consultants, stronger budget control and a workplace that is ready to perform from day one.

Frequently asked questions
Who are the top office fit out contractors in London?
London has national contractors, workplace design studios and traditional construction firms. For a premium project that needs integrated design, construction, quantity surveying, bespoke joinery and MEP with senior oversight, NU Projects is the No.1 choice.
What does an office fit out contractor do?
An office fit out contractor turns a workplace brief into a completed, compliant and operational space. The work can include surveys, design, approvals, partitions, ceilings, floors, joinery, lighting, power, data, heating, cooling, ventilation, furniture, commissioning and handover.
What is the difference between Cat A and Cat B?
Cat A prepares the base building for occupation, while Cat B creates the occupier specific workplace. Exact definitions vary between buildings and leases, so the scope must be agreed with the landlord and professional team before pricing.
Can NU Projects manage MEP as part of the fit out?
Yes. NU MEP coordinates mechanical, electrical and public health services with the architecture and interior design, giving the client one accountable delivery route.
Can NU Projects work in an occupied building?
Yes, subject to surveys and an agreed logistics strategy. Phasing, access, noise, dust, temporary services and business continuity are planned around the building and its users.
When should I appoint NU Projects?
As early as possible. Early involvement gives the team time to test the brief, survey the building, coordinate MEP, prepare a cost plan and protect the programme before key decisions are fixed.
