Office Fit Out in London: The Complete Guide for 2026

A London office carries more weight than an address. It signals to clients, helps you compete for talent, and shapes how your team works day to day. A fit out done well earns its cost back through all three. This guide covers the full journey, from the state of the London market in 2026 to choosing a contractor who can deliver in the capital.

The London office market in 2026

Demand for quality office space in London has strengthened as businesses bring teams back together. Occupiers now compete for well-located, well-fitted space, and landlords respond by upgrading their stock. The result is a market where a tired office stands out for the wrong reasons, and where a sharp fit out helps a business hold its own against bigger names.

Hybrid working has changed what companies chose to fit, more than whether they fit out at all. Teams come in fewer days but expect more from the space when they do. Collaboration zones, quality meeting rooms, and hospitality-grade breakout areas now take floor area that banks of desks once filled. The offices winning attention in London reflect that shift.

What a London fit out involves

The process follows the same shape as any fit out, with a few pressures specific to the capital. Access, deliveries, and working hours all need tighter planning in central London buildings, and building management teams often set conditions on when noisy works can run. An experienced contractor plans around those constraints from day one, so they cost you nothing.

1. Survey and brief. A measured survey of the space, plus a working session on headcount, layout, and how your team uses the office.
2. Design. A floorplan or 3D render that turns the brief into a proposed design solution including  zones for work, meetings, collaboration, and hospitality.
3. Costing and approvals. A detailed quote, a schedule of works, and any landlord consents the building requires.
4. The build. Fit out works run by a project manager who handles the site, the building management, and the programme.
5. Handover. Snagging, sign-off, and a working office ready for the team.

Cat A and Cat B in the London market

Most London leases hand tenants a Cat A space: raised floors, ceilings, and basic services, with none of the character or function a business needs. The Cat B fit out turns that blank canvas into your office, adding partitions, meeting rooms, finishes, branding, and furniture. Some landlords now offer Cat A+ space with a basic fit out included, which suits smaller occupiers who want to move fast.

Knowing which category your space sits in shapes your budget and programme. Our Cat A and Cat B fit out services page explains the difference in detail, and our team can assess a space before you sign a lease, so you know the cost of making it yours.

What a London fit out costs

UK office fit out costs in 2026 range from around 90-190 pounds per square foot depending on the specification, and London projects tend to sit toward the upper half of that range. Central London adds cost through access constraints, building conditions, and higher labour rates, though the gap narrows outside Zone 1. For a full breakdown by specification level, see our office fit out cost guide.

Your budget also has to cover more than the build. Furniture, IT and cabling, professional fees, and dilapidations on the space you leave all belong in the plan. A contractor who prices the whole picture at the start protects you from the surprises that stretch London projects.

Choosing a fit out company in London

London has no shortage of fit out firms. The differences show in delivery: how a contractor handles building management, how they keep a programme moving when access is restricted, and whether the team that wins your business is the team that runs your site. Ask for London references, visit some of the projects before you commit, and look for a company that has worked in buildings like yours.

Rap Interiors has delivered fit outs across the capital for more than three decades, including projects for We Soda, Pick Everard, Vestey Holdings, and Ignition Creative, along with an agile workspace for Hudl in Islington. The team runs London projects from survey to handover with a dedicated project manager throughout.

Frequently asked questions

How much does an office fit out cost in London?

London fit outs typically sit in the upper half of the UK range of 90-190 pounds per square foot, driven by specification, building condition, and access. The reliable figure comes from a measured survey and a detailed specification, which any good contractor will provide before you commit.

How long does a London office fit out take?

A straightforward fit out of a smaller office can complete in six to eight weeks, while a full floor with complex services can run three to six months. Central London buildings sometimes restrict working hours, which a contractor should build into the programme from the start.

Do I need landlord consent for a fit out?

Usually, yes. Most London leases require a licence for alterations before fit out works begin. Your contractor should prepare the drawings and specifications the landlord needs, and factor the approval period into the programme.

Can you fit out our office while we work in it?

Often, yes. Phased works, sectioned-off areas, and out-of-hours working all keep a business running through a fit out. The approach depends on the space and the scope, which is worth discussing at the survey stage.
