Rap Interiors designs and delivers office fit outs across London, turning empty floors and tired workspaces into offices that work for your team and impress your clients. With more than three decades in the industry and a portfolio of completed London projects behind us, we handle everything from the first survey to the finished office, with one project manager and one point of accountability throughout.

A fit out partner that knows London

London fit outs come with their own demands. Building managers set the rules on access, deliveries, and working hours. Landlords require consent before works begin. Floorplates range from modern towers to converted warehouses, and each behaves differently once the design meets the building. We have delivered fit outs across the capital for years, and that experience shows in programmes that hold and budgets that behave.

Our clients stay with us, and the numbers say why: more than sixty percent of our work comes from repeat business and referrals. When a fit out finishes on time, on budget, and to the standard the design promised, businesses come back for the next one.

What our London fit out service includes

  • Pre-lease building surveys, so you know what a space will cost to fit out before you commit to it.
  • Space planning and interior design, developed around your headcount, your working patterns, and your brand.
  • Cat A and Cat B fit outs, from stripped-back shells to fully finished, furnished offices.
  • Full project management, building liaison, and out-of-hours working where the building requires it.
  • Furniture specification, supply and installation, with reuse and refurbishment options where they make sense.
  • Finance options that spread the cost of the project, keeping capital in your business.

Our London portfolio spans corporates, professional services, creative businesses, and charities. We fitted out offices for CircleSquare and We Soda, delivered an agile workspace for sports technology company Hudl in Islington, created a corporate office for Pick Everard , and completed projects for Family Mosaic and Social Finance. Each project page on this site shows the space, the brief, and the result, so you can judge the work directly.

Frequently asked questions

How much does an office fit out cost in London?

It depends on the size of the space, its condition, and the specification. UK fit out costs in 2026 run from around 55 to 120 pounds per square foot, with London typically in the upper half of that range. Our cost guide breaks the figures down. Get in touch to discuss your project and how we can provide a tailored quote for your project.

Can you assess a building before we sign the lease?

Yes, and we recommend it. A pre-lease survey can give you a guide what each shortlisted building will cost to fit out, which protects you from spaces that look cheap on rent and prove expensive to make usable.

Do you handle both design and build?

  1. Yes. We run projects as a single design and build partner, which keeps the design intent and the build cost in the same conversation and gives you one point of accountability from survey to handover.

Can you fit out our office while we keep working?

  • In most cases, yes. We phase works, section off live areas, and run noisy trades out of hours, so your business keeps trading through the project. The phasing plan is agreed with you before works start.
