Office fit-out in Bromley is mostly small-scale work. The borough is largely residential, and its protected office space sits in the Business Improvement Areas in Bromley Town Centre, with smaller suites over shops, in converted houses and in the parades elsewhere. We fit out and refit those spaces for the business taking them: strip-out, partitions, ceilings, lighting and power, meeting rooms, tea points and WCs, working to the landlord's licence and the building regulations for non-domestic work.
For Bromley, 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 Bromley: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

Where Bromley's office space actually is
Bromley's protected office floors are in the Business Improvement Areas in Bromley Town Centre. The Local Plan says Article 4 directions are in place there, removing the right to change from office to residential use, so the suites in those areas are expected to stay offices. For a tenant that means older town centre floors that are refitted rather than replaced, often with a shared stair or lift and a landlord's services contract already running.
Beyond the town centre, an office in Bromley is usually a suite above a shop, a converted house used by a practice, or a small unit in a neighbourhood parade. The London Plan names Croydon town centre as the strategic outer London office location, so the largest outer London office floors are planned for there rather than here. An upper floor over a shop may be a flat, though, and using a flat as an office needs planning permission first. For a Bromley business that means fit-outs of one floor or a few rooms, often in an older building with a shared stair and limited risers.
Cat A, Cat B and the landlord's licence in Bromley
Cat A and Cat B describe who fits what in a Bromley office. Cat A is the landlord's base finish: ceilings, basic lighting, heating and cooling, raised floors or perimeter trunking, and toilets. Cat B is your layout on top: partitions, glazed meeting rooms, a tea point, reception, extra power and data outlets, and decoration. A small suite over a shop is often let as a plain shell, so a tenant there may need both stages in one contract.
Nothing starts without the landlord's licence for alterations. The landlord will want drawings, a method statement and the programme, and may send its own surveyor to approve the design. The data cabling is coordinated with your IT supplier, who terminates and tests it, while we provide the containment and power. Keep the licence drawings for your lease file, because at the end of the term the landlord judges dilapidations and reinstatement against them.
Building regulations for non-domestic work in Bromley
An office fit-out in Bromley is non-domestic building work, and new partitions change what building control has to see. Bromley building control does not publish a fixed charge for commercial and other non-domestic work, and asks applicants to request an individually determined charge. An office is covered by the fire safety order, so the work goes in on full plans rather than a building notice, and Bromley aims to issue approval within five weeks, or two months where the period is extended by agreement.
The drawings are tested on three points. Part B covers fire and means of escape: enclosed meeting rooms must not create inner rooms without a safe exit, and emergency lighting and alarms follow the new layout. Part M looks at accessible WCs and door widths. Part L applies to the new lighting and its controls. Under the CDM Regulations you, as a commercial client, carry duties of your own, including appointing a principal designer and principal contractor in writing where more than one contractor will work on the job.
Working around a Bromley office that stays open
When a Bromley fit-out happens in a building that is still in use, the programme is split around the people working there. Noisy work such as breaking out, drilling concrete or cutting studs is best kept away from occupied floors during the working day. A contractor can apply to Bromley for prior consent to work outside normal hours under Section 61 of the Control of Pollution Act 1974, which suits a noisy weekend strip-out in a shared block.
The landlord's services are the other interface. In a multi-let Bromley building the fire alarm, the heating and cooling plant and the risers usually belong to the landlord and are paid for through the service charge. A new detector or fan coil is therefore connected by the landlord's contractor or with its written approval. We agree those tie-ins, and any alarm isolation during dusty work, with the building manager before the start date. Photographs of the space on the day you take it, filed with the licence drawings, are the evidence you will want when dilapidations are assessed.
- Tea points and kitchenettes on the existing risers
- Fire doors, self-closers and fire stopping to the office fire strategy
- Internal office signage and manifestation on glazed screens

Working With GS Renovation in Bromley
An office fit-out is judged on the day your staff move in, so we price and plan backwards from that date. We work from your layout or your designer's drawings and the landlord's pack, give a dated sequence from strip-out to handover, and phase noisy work away from occupied floors. The founder visits before pricing to check the ceiling void, the risers and the escape routes. You get one contract, one contact, and the building control and electrical certificates your landlord will ask for.
- Honest updates if a date or a detail has to move
- Lease reinstatement clauses read before any partition is fixed to the structure
- One named contact for the landlord, the building manager and your office manager

FAQ
Frequently Asked Questions about Office Fit-Out Bromley
How much does an office fit-out cost in Bromley?
Published guides put the construction part of an office fit-out at £70 to £120 per square foot (Oktra, 2026) and an all-in London fit-out at £148 to £359 per square foot (Cushman and Wakefield, 2026). The survey and your layout fix the scope, and the quote itemises strip-out, partitions, ceilings, lighting, power and making good.
Where are the office areas in Bromley for a fit-out?
In the Business Improvement Areas in Bromley Town Centre first. The Local Plan says Article 4 directions there remove the right to change offices to homes, so that stock stays in office use. Elsewhere, office space tends to be smaller: rooms above parade shops and practices in converted houses. We fit out spaces of that size, from one room to a whole floor.
What is the difference between Cat A and Cat B in a Bromley office?
Cat A is the landlord's base build: ceilings, lighting, heating, floors and toilets. Cat B is the tenant's layout: partitions, meeting rooms, kitchen point, furniture power and branding. Some Bromley suites are let as a shell with neither, so check the lease schedule to see which items you are paying for before the design starts.
What does Bromley building control charge for an office fit-out?
There is no published fixed charge. Bromley building control asks anyone doing commercial or other non-domestic work to request an individually determined charge. Ask as soon as the layout is drawn, so the figure sits in the budget before the lease is signed. A later change such as an extra WC may alter it.
How long does Bromley take to approve full plans for an office?
Bromley aims to issue a full plans approval notice within five weeks, or two months where the period is extended by agreement. Submit early, because the fire strategy for new partitions and meeting rooms may need changes before approval. We can start strip-out while the application runs, as long as the landlord agrees.
Can office fit-out work in Bromley run at weekends or at night?
Yes, with prior consent for noisy work. In Bromley a contractor can apply for consent to work outside normal hours under Section 61 of the Control of Pollution Act 1974. Quiet trades such as decorating, ceiling tiles or cable pulling often run in the evening without it, as long as nobody nearby is disturbed.
Why can a Bromley office fit-out not go in on a building notice?
Because an office is covered by the Regulatory Reform (Fire Safety) Order 2005. Under regulation 12 of the Building Regulations 2010 a building notice cannot be given for work to such a building, so new partitions, doors and alarm changes go in on a full plans application. The approved drawings then record the escape routes, fire doors and emergency lighting that the responsible person relies on once you move in.
What CDM duties does a client have for a Bromley office fit-out?
Under the CDM Regulations a commercial client must appoint a principal designer and principal contractor where more than one contractor is involved, give them the information they need, and allow enough time and resources for the work. We prepare the construction phase plan as contractor and share it with you before work starts.
What happens to the fit-out at the end of the lease?
The landlord may require reinstatement under the dilapidations clause, which can mean removing partitions, making good ceilings and returning the space to its original condition. The licence for alterations usually sets out what must come out. We keep the as-built drawings, so pricing the strip-out later is straightforward.
