London’s commercial property market moves fast. Whether you’re taking on a new office lease, repositioning a retail unit, or refreshing a flagship space, the fit out contractor you choose will determine whether your project runs smoothly, or not at all.
At Eden Build, we’ve been delivering commercial fit outs across London and the wider UK for years. Here’s what clients should know before they appoint a contractor.
What Does a Commercial Fit Out Contractor Actually Do?
A commercial fit out contractor takes a space — whether that’s a raw shell, a Category A shell, or an existing office and transforms it into a fully functioning, finished environment for your business.
That includes everything from partition walls, suspended ceilings and raised access floors, through to M&E (mechanical and electrical) installations, joinery, decorating, and the final snag. A good contractor manages the entire build phase, coordinating all trades to keep your programme on track.
Category A vs Category B: Knowing the Difference
In London’s commercial office market, fit outs typically fall into two categories:
- Category A (Cat A): Brings a shell to a lettable standard — grid ceilings, raised floors, basic M&E, lighting and HVAC. Usually carried out by the landlord or developer.
- Category B (Cat B): The tenant fit out. This is where your brand, culture and ways of working come to life — meeting rooms, open-plan areas, kitchens, AV, branding and bespoke joinery.
Some contractors only work at one level. Eden Build operates across both, which means we can take a project from shell to fully occupied without handover delays between contractors.
What Sets a Good Contractor Apart in London?
London projects come with unique pressures: restricted site access, congestion charging zones, strict noise restrictions, and landlords with demanding licence-to-alter requirements. The contractor you appoint needs to understand these constraints before the first tool is on site.
Look for:
- A strong track record of completed London projects — ask to see case studies
- Experience working within managed buildings and co-ordinating with building management
- A clear programme and cost plan from day one
- Full accreditations — CHAS, Constructionline, SafeContractor
- A single point of contact who’ll see your project through from survey to handover
