Office Fit-Out Southall

Office fit-out in Southall is small-scale work, and it is honest to say so. Southall is a Major Centre in Ealing's Development Strategy, and the office work that arises here is in rooms above shops on and around the Broadway, small professional suites and the odd studio, not an office district. These are the spaces an accountant, solicitor, agent or tutor takes, and the fit-out covers partitions, ceilings, lighting, power, a tea point and WCs, built to the landlord's consent and the building regulations.

For Southall, 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 Southall: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

The office space Southall actually has

Southall's offices sit inside its shopping centre rather than beside it. Ealing's Development Strategy names Southall a Major Centre, with Ealing as the borough's Metropolitan Centre, and in the London Plan network a Major centre ranks below Metropolitan and above District. On the ground that means upper floors over shop units on the Broadway and nearby streets, reached by a side door and a narrow stair, plus the occasional small suite in a newer building.

That shapes every office job here. Floor areas are modest, the stair is often the only way in and out, and the building may be shared with a shop below and a flat above. A fit-out has to fit that shell: lightweight partitions that the old floor can carry, lighting that works with low ceilings, and a small kitchenette rather than a staff canteen. We survey the floor, stair and services first, and design the layout around what the Southall building can take.

Cat A, Cat B and the works in a Southall office

Cat A and Cat B are the two stages of an office fit-out, and it helps to know which one your Southall lease gives you. Cat A is the landlord's base: a clean shell with ceilings, basic lighting, heating and WCs working, ready for a tenant. Cat B is the tenant's own fit-out on top of it: partitions and glazed screens, a meeting room, the tea point, extra power, data containment and decoration. In an older room above a shop there may be no Cat A at all, so the job starts further back.

The typical scope here is a strip-out of the last tenant's fittings, new stud or glazed partitions, a suspended ceiling where the height allows, LED lighting and small power, and a tea point with a sink. We run cable containment and leave draw wires for the data, and your IT supplier installs and terminates the network. Signage inside the office and decoration finish the job. The rewire and new circuits are tested and certified by a registered electrician.

Landlord consent, building control and CDM for a Southall office

Before work starts, the landlord's licence for alterations needs to be in place, because an office lease normally controls partitions, services and anything fixed to the structure. An office falls under the Fire Safety Order, so a building notice cannot be used. The fit-out then needs building regulations approval where it touches means of escape and fire separation (Part B), access and WCs (Part M) or fixed lighting and services (Part L). Ealing runs its own building control and, on a full plan application, checks the plans within 10 working days and issues a decision notice within five weeks unless two months has been agreed.

Ealing also says it has severe backlogs with customers who reverted to it after their private building control company failed, so choose the route early. Since 1 February 2026 Ealing site inspections run on Monday, Wednesday and Friday, and we time the fire-stopping and ceiling stages around them. A business client also has duties of its own under the CDM Regulations, including appointing competent contractors and allowing enough time. We explain those duties at the start and prepare the construction phase plan for the job.

Office to home changes and lease-end works in Southall

Office space in Southall can also leave the market altogether. Class MA of the General Permitted Development Order allows a change from Class E, which includes offices, to homes. It needs two years in Class E use and never applies to a listed building. Prior approval covers matters including natural light in every habitable room, and London Plan Policy SD8 asks boroughs to use targeted Article 4 Directions where justified to sustain town centres. For an office tenant this is background rather than a decision: it explains why an upper floor on the Broadway may be marketed for flats rather than re-let as an office.

The decision a tenant does face is at the end of the lease. Dilapidations clauses usually require the space to be handed back in repair and, where the landlord asks, with the tenant's partitions and alterations removed. We price reinstatement alongside the fit-out so you know the exit cost at the start. On a lease-end job in Southall we strip back to the condition in the schedule and make good the ceilings, floors and decoration for the landlord's surveyor.

The GS Renovation Difference in Southall

A small office fit-out lives or dies on its programme, because rent is often running while the work is done. We give you a written sequence from strip-out to handover with the building control stages marked, keep noisy work inside the permitted hours with quiet work after hours where the building is occupied, and keep the stair and entrance clear for neighbours. One team covers the builders' work, partitions, ceilings and decoration, with a registered electrician certifying the installation and your IT supplier coordinated around the containment we install.

• Waste cleared as we go, not left piled up outside
• Every new office circuit certified to BS 7671 by a registered electrician
• Lease reinstatement clauses read before any partition is fixed to the structure
