Flat Refurbishment Hillingdon

Flats are 34% of the homes in Hillingdon, and refurbishing one means working inside a building you share. The blocks range from post-war estates to newer developments, since 16% of all homes in the borough date from 2000 or later, plus houses already split into flats. Before any tools arrive, the lease, the managing agent's rules and the neighbours below shape what can change. We renew kitchens, bathrooms, wiring, heating and floors inside the flat footprint, and plan deliveries, noise and protection around the block.

For Hillingdon, published UK averages put a full flat refurbishment at £33,000 to £48,000 and a basic one, with budget kitchen and bathroom fittings, at £15,000 to £18,000, and London flats usually cost more (Checkatrade and MyJobQuote, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hillingdon: we refurbish the flat within the terms of your lease and licence to alter, protect the common parts throughout, and a registered electrician certifies the new consumer unit and circuits.

The lease comes first on a Hillingdon flat refurbishment

34% of homes in Hillingdon are flats, and a flat refurbishment starts with the lease rather than the tools. A lease will often require the freeholder's written licence to alter before walls move, floors change or a bathroom is relocated. The managing agent may also set working hours, protection for common parts and rules on where skips and deliveries go. Send us the relevant lease clauses at quote stage, so the programme reflects the consent period.

The kind of block changes what the lease cares about. A flat on a Hillingdon post-war estate may have a council or housing association freeholder with its own alteration process. A flat in a block built since 2000 is likely to have a managing agent with written building rules and booked lift slots. A flat in a converted house may have a small freeholder with no agent at all, which makes the licence quicker but the paperwork thinner.

Housing in Hillingdon

By the valuation list's count, Hillingdon holds about 118,240 homes, 66% houses and 34% flats; by age, 4% were built before 1919, 37% between the wars and 59% since 1945.

Shared services, floors and fire safety in a Hillingdon block

Services in a flat are shared in ways a house is not. The soil stack, the rising water main and sometimes the heating belong to the building. A new bathroom has to connect to the stack where it runs, and we agree access with the managing agent for isolating water. Inside the flat we renew the consumer unit and wiring, certified by a registered electrician, and replace a gas boiler or older electric heaters with a system the block allows.

Replacing carpet with hard flooring above another flat is a common cause of complaints in any Hillingdon block, so the specification should include an acoustic underlay or floating floor the lease allows. A leak into the flat below is the other risk, so wet areas get a tanking layer before tiling. The flat entrance door and the compartment walls are matters for the freeholder or responsible person under fire safety law, so any change to them is agreed in writing first.

Noise, deliveries and parking when you work inside a Hillingdon block

Hillingdon limits building work audible at the site boundary to weekdays from 8am to 6pm and Saturday mornings from 8am to 1pm, and allows none on Sundays or public and bank holidays. Inside a block, the managing agent's hours are often tighter than that, and a neighbour through the wall hears drilling long before anyone on the street does. We put the breaking out of old tiles and screeds into the first days, then move on to quieter fitting work.

Getting materials up and waste down is half the logistics. We protect the lift car and stair treads, carry boards and plasterboard in at agreed times and bag waste rather than stacking it in the common parts. If a skip is needed on the road, Hillingdon puts the permit on the skip supply company, not the builder or the flat owner. Where the block has its own car park, the agent may allocate a bay for our van, which saves the day's first hour.

Letting a refurbished Hillingdon flat: EPC and licensing

A buy-to-let flat in Hillingdon has to reach the energy standard before a new tenancy. Since 1 April 2020 a landlord may not let, or continue an existing let of, a domestic property rated below E unless a valid exemption is registered. In a flat the practical measures are narrower than in a house: heating controls, an efficient boiler or modern storage heaters, LED lighting and draught-proofing of the windows the lease lets you change.

If the flat is let to sharers, licensing also applies. Hillingdon's boroughwide additional HMO licensing scheme covers shared properties with fewer than five residents from two or more households, so a three-bedroom flat let to unrelated sharers may need a licence and its conditions shape the refurbishment. The landlord applies for any licence. Where a block is a higher-risk building under the Building Safety Act, building control sits with the Building Safety Regulator, except for work under a competent person scheme, so the managing agent confirms the route first.

• Buy-to-let refurbishments between tenancies, with the EICR and gas safety record arranged with the certifying engineers
• Method statements and product details for the freeholder's licence to alter
• Rewires inside the flat, signed off at the end by a registered electrician
