Office Fit-Out Hayes

Office fit-out in Hayes can mean an upper floor above shops in Hayes District Centre, a small suite elsewhere in UB3 or UB4, or space inside the Hayes Opportunity Area. Hillingdon counts the district centre as one of the two largest of its five. The work we do here is at the small end: partitions, ceilings, lighting, a tea point and WCs for a firm taking or reworking its own space, built to the landlord's licence and non-domestic building regulations.

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

What office space in Hayes looks like to a fit-out builder

The office work that reaches a builder of our size in Hayes is small units, not headquarters floors. Hillingdon names Hayes District Centre as one of the two largest of its five district centres, and the office space to expect around it is on upper floors above shops, often reached by its own door and stair. Small professional suites and studios make up the rest. Each suggests a different fit-out, from a two room refresh to a whole floor stripped back.

The first question on a Hayes office is what the landlord hands over. A Cat A space has finished ceilings, lighting, heating and cooling and raised floors or perimeter power, ready for a tenant to plan. Cat B is the tenant's own layout on top: meeting rooms, glazed screens, a tea point, data points and finishes. Older rooms above shops often have neither, so the fit-out starts with basic services before any layout can be set.

Hayes offices and the Class MA Article 4 Direction

Hillingdon has limited office to home conversion in parts of the borough, including Hayes. On 14 July 2022 it confirmed a non-immediate Article 4 Direction removing permitted development rights to change from commercial, business and service uses to dwellinghouses. The direction first came into force on 24 September 2022. The Secretary of State then reduced its area, and the modified direction came into effect on 27 March 2024, with a map covering the Hayes Opportunity Area.

Inside that area, turning offices into homes needs full planning permission rather than prior approval. A separate strategic employment land direction has required planning permission for a change to residential in its identified locations since 22 November 2017. For a business fitting out an office in Hayes, the direction matters mainly as context. The building's lawful use stays commercial, which is the planning starting point for a tenant reworking the space for its own staff.

Building regulations for office work in Hayes

Office fit-out in Hayes is non-domestic work under the Building Regulations wherever it is building work. New partitions can change escape routes and fire separation under Part B, new WCs and entrances bring in Part M access, and new lighting and services fall under Part L. A Hillingdon full plans application covers domestic or commercial works and needs detailed plans and structural calculations. On a full plans application you will normally receive a formal decision within 5 weeks.

A building notice cannot be used for work on premises covered by the fire safety order, which includes offices, so a Hayes office goes through full plans. Hillingdon does not issue plans approval on a building notice in any case. If a previous tenant altered the space without approval, Hillingdon accepts regularisation applications for non-domestic works commenced on or after 11 November 1985, which clears the history before you invest in new finishes.

Working in an occupied Hayes building and leaving at lease end

An office floor in Hayes usually sits above or below other businesses, so the programme is built around them. Hillingdon only permits building work audible at the site boundary from 8am to 6pm Monday to Friday and 8am to 1pm on Saturday. Inside an occupied building, the landlord may also want the loudest work kept to the edges of that day. We agree those hours in writing before the licence for alterations is signed, and keep quieter work for the core day.

As the client on a commercial job, your business has duties of its own under the CDM Regulations, including appointing a principal designer and principal contractor when more than one contractor works on the project. We take the principal contractor role on our jobs. At the end of the lease, dilapidations and reinstatement follow the licence you signed, so we give you a record of what was installed to make that conversation with a Hayes landlord shorter.

We build to your designer's approved drawings, coordinate the data cabling with your IT supplier and schedule noisy work around the other occupiers.
