Office fit-out in Chiswick has two real settings. Hounslow names Chiswick Business Park as one of its Key Existing Office Locations, and Chiswick, a Major Centre in the Local Plan, is another, which takes in upper-floor offices in the town centre. So the work here can range from a suite in a business park building to a few rooms above a shop on Chiswick High Road or near Turnham Green. We strip out and build partitions, ceilings, lighting, power, tea points and WCs, and hand the space over ready for your furniture and IT.
For Chiswick, 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 Chiswick: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

Business park suites and offices above Chiswick High Road
The office space a Chiswick business fits out is mostly one of two kinds: a suite in a managed building or an upper floor in the town centre. Hounslow lists its Key Existing Office Locations as its four town centres plus office developments at Bedfont Lakes, Chiswick Business Park and two areas on the Great West Road. In a business park building the landlord's fit-out guide usually governs the details: which ceiling grid and lighting you keep, how you connect to the base build services and when the goods lift is yours.
Above a shop on Chiswick High Road the job is smaller and less predictable. A first floor office may have a single narrow stair, an old electrical supply shared with the shop and no suspended ceiling at all. We survey the incoming supply, the route out in a fire and the stair width for deliveries before pricing, because those decide the programme more than the partitions do. Whichever setting you are in, the brief starts with how many desks, meeting rooms and quiet rooms the team needs.
Cat A, Cat B and the landlord's licence in Chiswick
Office leases and agents talk about Cat A and Cat B, and a Chiswick fit-out quote should say which it covers. Cat A is the landlord's basic finish: raised floor, suspended ceiling, lighting, heating and cooling and finished walls, with no rooms. Cat B is your layout on top of it: partitions, glazed screens, meeting rooms, a tea point, lighting controls, small power to the desks and decoration. Taking a Cat A suite means a Cat B fit-out; taking an older floor may mean both.
Nothing starts until the landlord has approved it. Your lease will ask for a licence for alterations, and the landlord or managing agent reviews the drawings, method statements and programme before issuing it. In a business park building that approval can include the fire engineer's comments on your layout. We prepare the contractor documents to the landlord's list, coordinate the data cabling with your IT supplier, and keep a record of what we changed so that dilapidations at lease end are easier to agree.
Building regulations and CDM duties for a Chiswick office
An office fit-out in Chiswick is non-domestic building work, and building control follows the scope. Hounslow says a full plans application is usually used for major projects such as alterations or a change of building use, and its Table F charges alterations, fit-outs and installations not covered elsewhere by the estimated cost of the works. The drawings show Part B escape routes and fire doors, Part M access and WCs, and Part L lighting and controls. We send product data early so the surveyor can sign off. A building notice cannot be used for an office, because the Fire Safety Order applies to it, so full plans come first.
The CDM regulations give a commercial client duties of its own, including making sure a principal contractor and a construction phase plan are in place before work starts. On a Chiswick fit-out we take the principal contractor role, write the construction phase plan, run inductions and keep the site safe for the landlord's staff and neighbouring tenants. You provide the pre-construction information, such as the asbestos survey, which the landlord usually holds for the building.
Out of hours work and the Class MA rules around Chiswick offices
Fitting out an office in an occupied Chiswick building often means some quiet work after hours. Hounslow permits noisy building work Monday to Friday 8am to 6pm and Saturday 8am to 1pm. Noisy work at other times needs Hounslow's prior Section 61 consent, which is rarely granted where homes are nearby. We schedule core drilling and strip-out inside those hours at times the landlord and other tenants accept, and keep the quiet trades such as ceiling tiles, second fix and decoration for the later shifts.
Office stock in Chiswick is also protected in planning terms. Hounslow's Class MA Article 4 direction, in force from 22 April 2025, removes the right to change Class E commercial, business and service uses to homes in town centres and key existing office locations. For a tenant this matters as context: offices in those places cannot become homes without a planning application, so the office stock around the High Road and the business park is protected.

FAQ
Frequently Asked Questions about Office Fit-Out Chiswick
Why do office fit-out quotes in Chiswick vary so much?
Because the scope differs. One quote covers only partitions and ceilings; another includes fire alarm changes, lighting, data containment, the tea point and out-of-hours working. Published guides give £70 to £120 per square foot for the construction element (Oktra, 2026). Compare quotes against the same written scope.
What is the difference between Cat A and Cat B for a Chiswick office?
Cat A is the landlord's shell finish: suspended ceiling, raised floor, lighting, heating and cooling and plain walls. Cat B is your fit-out on top: partitions, meeting rooms, a tea point, small power, signage inside and decoration. Where a Chiswick Business Park suite is let at Cat A, the tenant's project is the Cat B layer, built to the landlord's fit-out guide.
Does a Chiswick office fit-out need building regulations approval?
Yes, where it includes building work, such as new WCs, altered escape routes or partitions that change how people get out in a fire. Hounslow says a full plans application is usually used for alterations and changes of use, and Table F charges fit-outs by the estimated cost of the works. The approved drawings cover fire escape, access and lighting efficiency, and the surveyor inspects before sign off.
Can an office fit-out in a Chiswick building be done at night?
Quiet work, yes. Noisy work, rarely. Hounslow permits noisy work Monday to Friday 8am to 6pm and Saturday 8am to 1pm. Noisy work at other times needs Hounslow's prior Section 61 consent, which is rarely granted where homes are nearby. The landlord's rules also apply. We put core drilling and strip-out in agreed slots inside those hours and do decoration and second fix after hours.
Can the landlord turn a Chiswick office into flats instead of refitting it?
Not under permitted development in the protected locations. Hounslow's Article 4 direction, in force from 22 April 2025, removes the Class MA right to change Class E uses to homes in town centres and key existing office locations, which include Chiswick Business Park. A landlord there needs a full planning application to convert.
What does a small office above a shop in Chiswick need?
A safe way out, enough power and a workable layout. Above a shop on Chiswick High Road we check fire separation from the shop below, the escape stair, the incoming electrical supply and where the WC and kitchenette can drain. Those decide the cost more than partitions or finishes, so we survey them before we price.
What are dilapidations and how does a fit-out affect them?
Dilapidations are the repairs and reinstatement a lease requires when you leave. Anything you add, such as partitions or a kitchenette, may have to come out at the end unless the landlord agrees otherwise. We keep a record of the alterations under the licence, and can price the strip-out and reinstatement at lease end when the time comes.
Who organises the data cabling in an office fit-out?
Your IT supplier specifies it and we coordinate it. We agree the routes, floor boxes and the comms room position with them before the ceilings close, install containment and power to suit, and give them clear access for pulling and testing cables. That keeps the network ready on the day the furniture arrives.
What does a business client have to do under CDM?
Provide pre-construction information, appoint a principal contractor where more than one contractor is involved, and make sure a construction phase plan is in place before work starts. On a fit-out we act as principal contractor and write that plan. The asbestos survey for the building usually comes from the landlord and forms part of your information.
