Office Fit-Out Hounslow

Office fit-out in Hounslow covers two quite different kinds of space. Council documents name two business parks, Chiswick Business Park and Bedfont Lakes Business Park, and an Article 4 direction protects key existing office locations. The borough also has smaller space, such as suites above shops in the town centres and offices in converted buildings. We fit out both at the scale they really are, from partitions, ceilings and lighting to tea points, WCs and the building regulations sign off.

For Hounslow, the construction part of an office fit-out is published at £70 to £120 per sq ft as a UK guide, and an all-in London office fit-out at £148 to £359 per sq ft (Oktra and Cushman and Wakefield, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hounslow: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

Where Hounslow's office space is, and at what scale

Hounslow's larger office space sits in a few named places. The council's HMO Article 4 direction names Chiswick Business Park and Bedfont Lakes Business Park among the areas it leaves out, and its Class MA Article 4 direction protects key existing office locations alongside the town centres and neighbourhood centres. Away from those places the borough is largely residential, so office work there is more likely to be a floor above a shop or a small suite.

The scale decides the fit-out. A floor in a managed business park comes with a landlord's fit-out guide, set working hours, base building services to connect into and a sign off process of its own. A suite above a parade shop may have no lift, a shared stair and a single electrical supply, so the first job is finding out what the building can carry. We visit before pricing and work to whichever set of constraints the space has.

Cat A and Cat B work in a Hounslow office

Cat A and Cat B describe who fits what in a Hounslow office. Cat A is the landlord's base finish: raised floor or screed, suspended ceiling, basic lighting, heating and cooling, and working WCs. Cat B is the tenant's layout on top: partitions and glazed meeting rooms, a kitchenette or tea point, extra small power, feature lighting, decoration and signage. Your lease and the agent's particulars say which has been done, and the difference shows up in both the programme and the price.

Hounslow's building control charges alterations and fit-outs not covered by its other tables under Table F, by the estimated cost of the work, so the scope you settle on also sets the building control charge. Data cabling is coordinated with your IT supplier, who specifies the points and the comms room. We build the containment, partitions and ceilings around their layout, so the cabling goes in at first fix and nothing is cut open after the ceiling tiles are laid.

Fire, access and working hours in an occupied Hounslow building

Office work in Hounslow needs building regulations approval when it changes the escape routes, the fire alarm, the WCs or the fixed services. Part B governs means of escape and fire separation, so a new meeting room must not create an inner room with no second way out. Part M covers accessible WCs and routes, and Part L covers lighting and controls. Hounslow's building control says a full plans application is usually used for major projects and alterations, and because an office is covered by fire safety law, full plans is the route to plan for.

Occupied buildings need careful timing. Noisy work in Hounslow is permitted Monday to Friday 8am to 6pm and Saturday 8am to 1pm, which clashes with the other tenants' working day. Where drilling and cutting must happen when the building is empty, Hounslow can grant Section 61 consent for works at specific times under agreed conditions. As the client on a commercial job you also have duties under the CDM Regulations, which we explain and help you meet.

Leases, dilapidations and Hounslow's protected office locations

Most office fit-outs begin with the landlord's licence for alterations, and many end with dilapidations. The licence lists the drawings the landlord approves and often a reinstatement clause, meaning the partitions and fittings you add may have to come out when the lease ends. Keep the approved drawings, the building control completion and the electrical certificates together, because a surveyor measuring dilapidations in a Hounslow office will ask for them. We can strip out and reinstate to the lease at the end as well.

Planning context explains why these offices stay offices. Hounslow's confirmed Article 4 direction removes the Class MA right to change Class E use to residential, and it applies to town centres, neighbourhood centres, industrial sites and key existing office locations. It came into force on 22 April 2025. For a tenant this is background, not a hurdle: it keeps the office stock in office use, and an internal office fit-out needs no planning permission unless the outside of the building or its use changes.

If the building is listed, the works themselves are a separate question: anything that affects its character, inside or out, needs listed building consent from Hounslow Council, and carrying it out without consent is a criminal offence.
