Commercial Fit-Out Belgravia

Commercial fit-out in Belgravia is work on customer-facing units set among stucco-fronted townhouses and mews: a shop, cafe or gallery on or near Elizabeth Street, a salon, or a clinic on a ground floor with homes above. Belgravia was first designated as a conservation area in 1968, so the shopfront and the sign are as much a part of the job as the counter. Towards Sloane Square, confirm which borough covers the unit before relying on Westminster's guidance.

For Belgravia, published UK guides put refurbishing a retail space at £1,500 to £3,000 per m² and a restaurant or cafe at £2,000 to £4,500 per m², and London units usually cost more (MyBuilder, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Belgravia: our own trades do the strip-out, back of house, counter fitting and finishes, and we coordinate the shopfront, extraction, electrical and fire specialists the unit needs.

The shopfront on a Belgravia unit needs its own consent

Changing the shopfront on a Belgravia unit generally needs planning permission. Westminster's shopfront design guide says the alteration and replacement of shopfronts generally requires planning permission, and that advertisements may need separate advertisement consent. A canopy with no advertising on it still needs planning permission. So the frontage and the sign are designed and applied for by your designer or agent before we order joinery. The interior can start while the decision is awaited, unless the building is on the statutory list and the internal work needs the council's consent too.

Security is the next question on a Belgravia frontage. The guide says security shutters normally need planning permission and roller shutters will not normally be given consent, so the brief should assume internal measures instead: laminated glazing, an internal lattice grille set back from the glass, or alarmed lighting. A traditional timber front of the kind a Belgravia conservation area favours costs more than a standard aluminium one and is priced from the consented drawing. A specialist fabricator makes the front to that drawing; we form the opening and threshold, install it and coordinate the sign installer so the frontage is finished in one visit rather than three.

Use class, extraction and food service in a Belgravia unit

The planning use of a Belgravia unit decides what it can trade as before any fitting starts. Class E covers shops, cafes, restaurants, clinics, gyms and offices, so moving between those uses does not normally need planning permission unless a condition on the premises says otherwise. Hot food takeaways, pubs and bars sit outside Class E as sui generis uses, so a change to one of them needs a planning application. Your designer or agent confirms the lawful use of the unit before the lease is signed.

Food brings extraction, and extraction is the hardest thing to route in a Belgravia building. An external extraction duct on a commercial unit normally needs planning permission in its own right, and in a Westminster conservation area its effect on the look of the building is part of that decision. Odour control, fan noise and the duct route are agreed with your designer and the landlord first, then built. A kitchen that serves food also needs a grease trap or separator on its drainage, positioned so it can be emptied without closing the unit.

Access, escape and the trading floor in a Belgravia shop

A Belgravia shop fit-out is designed around the customer's route in and out. Part M asks for a reasonable approach to an accessible entrance and, where WCs are provided for customers, an accessible WC where space allows, which is hard at a stepped townhouse threshold and is worked out on the drawings early. Part B covers the escape route from the sales floor and any lower-ground stockroom. Counters, display units and service areas are then laid out so they never narrow that route below what the fire strategy needs.

Westminster issues its completion certificate only once the fees are paid and the electrical and gas certificates are in, so a fixed opening date depends on that paperwork as much as on the shopfitter. Floors are chosen for trading: slip resistance at the entrance, a hard-wearing finish behind the counter and level transitions between areas. Lighting is designed for the goods as well as for Part L, and the circuits are certified by a registered electrician. In a Belgravia unit with a low ceiling, feature lighting is fixed to a grid rather than cut into old plaster.

Fitting out beside Belgravia residents: hours, deliveries and landlords

Where a Belgravia commercial unit shares a wall or a floor with homes, the fit-out is programmed like a residential job. Westminster's normal window for noisy work is Monday to Friday 8am to 6pm and Saturday 8am to 1pm, and noisy work outside that window needs prior consent through a Section 61 application at least 28 days before works start. Noisy strip-out out of hours is therefore planned weeks ahead, not arranged the night before, and only quiet work such as decoration runs late without it. Residents are told the dates in writing, and the landlord's consent and your duties as a commercial client are settled first.

Deliveries and the pavement come next on a parade. Westminster needs a temporary structure licence for hoardings, fencing or scaffold placed on the pavement, and its guidance keeps the footway at least 1.5m wide around works, so a Belgravia shopfront replacement is sequenced to keep shoppers and neighbours moving past. Counters, display units and shopfront glazing are timed for early deliveries, when the street is quieter. Where a neighbouring shop keeps trading, dust screens and a clean entrance stay in place throughout.

Working With GS Renovation in Belgravia

A Belgravia shop, cafe or clinic owner needs a fit-out contractor who can finish the frontage and the interior in one programme without upsetting the flats above. We give a written quotation after a site visit, build to the consented shopfront and interior drawings, coordinate the sign maker, extraction specialist, electrician and fire alarm installer, and hand over the certificates building control needs. The founder has more than thirty years of hands-on experience, and a fixed opening date is planned backwards from the start.
