Office Refurbishment Contractors in London
Your office might have the right address and the wrong layout. JTH Projects manages office refurbishment projects across London, working with the building you already have rather than starting from a blank shell, and planning the work around how your business actually operates while it happens.
Most businesses that come to us aren’t starting a project from scratch. They have an office that no longer fits how the team works, a layout that was designed for a different headcount, finishes that have worn past the point of a quick refresh, or building services that are starting to hold the business back.
If this sounds familiar, we are ready to explore the ideal office refurbishment solutions with you. Get in touch with us to discuss your needs and get expert advice with a free quote.
End-to-End Office Refurbishment Services in London
London’s commercial buildings vary more than a single specification can cover. A refurbishment in a converted period building in an inner borough runs differently to one in a purpose-built 1980s office block, and both differ again from a floor in a modern multi-tenant tower with a managing agent, shared lifts and building-wide access protocols. Some London offices sit in older or conservation-area buildings where alterations are more restricted than a purpose-built block allows.
JTH Projects is office refurbishment contractor in London, we help businesses reconfigure, update and improve their existing workspace. From managing the construction work, building services, and finishes to final handover, you get one coordinated project with minimal noise and unnecessary disruption.
That means your refurbishment can be managed as one joined-up process. The result should not simply be an office that looks newer. It should be a workplace that makes better use of the existing building and supports the way your business operates.
Why Businesses Choose JTH Projects for Office Refurbishment Services in London
We deliver office refurbishment projects across London and Surrey. Most London office refurbishments happen while the business is still in the building, or while other tenants are still using theirs. That changes how the project has to run.
– Phased working: splitting the project so parts of the office stay usable while others are under construction.
– Protection of finished and occupied areas: screening, hoarding and floor protection so work in one zone doesn’t affect another.
– Noise and dust control: scheduling disruptive work outside core hours where needed.
– Access and deliveries: working within loading bay booking windows and lift access that many central London buildings restrict to set times, and factoring congestion charges and ULEZ hours into delivery scheduling.
– Fire escape routes and shared areas: keeping corridors, stairwells and emergency exits clear throughout.
– Landlord and managing agent coordination: agreeing on working hours, permits to work and building rules directly with whoever manages the building, so you’re not caught in the middle.

What's Included in a London Office Refurbishment
An office refurbishment can cover part of a floor or the whole office. As Principal Contractor, JTH can coordinate the construction programme, specialist trades and relevant site activities while maintaining communication throughout the project. The scope we agree with you typically draws from:
- Site preparation and strip-out services
- Internal reconfiguration and partitioning
- Upgrading suspended ceilings
- Installing new lighting layouts
- Renewing floor carpet, tiles or timber
- Complete electrical and mechanical services
- Joinery and glazing for office interiors
- Full office interior decoration and finishing
- Remodelling washrooms, welfare areas and breakout facilities
- Testing and handover — commissioning services and snagging
We scope and price this line by line after the first site visit, so you know what’s included before work starts.
Plan Your London Office Refurbishment with JTH Projects
Some of the most common factors in the refurbishment process for an operating business—we always consider them. Access may be restricted. Deliveries may need to be carefully scheduled. Work may need to take place alongside other businesses in the building. Existing layouts and services may also limit how quickly or extensively an office can be changed.
JTH Projects helps London businesses plan refurbishments around the building they already occupy rather than treating every project as a blank canvas. Whether the requirement is a focused internal refurbishment or a more extensive reconfiguration, the aim is to deliver a finished workplace that works better for the business using it.
- One contract, one point of responsibility — we act as Principal Contractor, so you’re not managing separate trades or chasing different programmes
- Every trade coordinated in-house — this removes the handover gaps between packages, which is where most refurbishment delays start
- Scope and cost set out before work starts — so variations stay the exception rather than the rule
- Direct coordination with landlords and managing agents — where building rules, access or permits to work need agreeing on your behalf
- Experience working around live, occupied premises — across offices, sales suites and commercial interiors throughout London and Surrey
We visit sites for office refurbishment across London and Surrey. It gives us the chance to see the space, understand how the building operates, and talk you through scope, access and a realistic programme before you commit to anything.
London Office Refurbishment FAQs
Can staff remain in the office while the refurbishment takes place?
Often, yes, particularly where the project is phased. Some works, such as full mechanical and electrical upgrades or a complete layout change, are easier to deliver with the space empty. We’ll set out what’s realistic for your project once we’ve seen the space and understood how much of it needs to stay in use.
How do you work with our landlord or managing agent during the project?
We agree on working hours, noise windows, access arrangements and any permits to work directly with them, so you’re not passing messages between us and the building. This is set up before work starts, not worked out as we go.
What's the difference between an office refurbishment and a commercial fit-out?
A fit-out generally starts from a bare shell and builds a working office from nothing. A refurbishment improves an office that already exists, whether that’s the layout, services, finishes or all three. Most of our London office projects are refurbishments for exactly this reason: the building and the business are already there.
How long does an office refurbishment in London take?
A single-floor refurbishment typically runs four to eight weeks. Larger projects, or ones involving significant mechanical and electrical work, usually take two to four months. We confirm a realistic programme after the first site visit.
Do you handle mechanical and electrical work as part of the refurbishment?
Yes. Mechanical and electrical installation is coordinated under the same contract as the rest of the works, alongside joinery, glazing, decoration and finishes, so you’re dealing with one team rather than separate specialists.
Do you cover offices outside central London?
Yes. We work across London and Surrey, including dedicated commercial fit-out services in Bromley and Croydon. If sustainability is a priority for your project, our article on sustainable office refurbishment in London covers what that can look like in practice.
