Flat Refurbishment Southwark

81% of Southwark's homes are flats, so flat refurbishment is the kind of renewal most owners here will meet. They range from post-war estates and riverside apartments to flats cut from Victorian terraces, and 27% of homes were built in 2000 or later. A leasehold flat comes with a lease, so the job starts with the freeholder's consent, the block's rules and a plan for getting materials in without upsetting the neighbours above and below.

For Southwark, 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 Southwark: 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.

Leases, licence to alter and the block's rules in Southwark

With 81% of Southwark's homes being flats, a refurbishment here usually starts with the lease rather than the council. Read the alterations clause first: many leases need the freeholder's written licence to alter before you move a kitchen, replace floors or touch anything structural, and the managing agent often asks for drawings, a method statement and the contractor's details. Allow time for that consent, because work that starts without it can breach the lease.

The block usually sets its own working hours, which can be tighter than the council's, and rules for lifts, bins and parking. We ask the managing agent for those rules at the start and build them into the programme. Common parts are protected with floor and wall coverings, lifts are padded or kept for residents where the agent requires, and waste goes out in bags on agreed days rather than piling up in the hall.

Housing in Southwark

The stock in Southwark runs to roughly 149,990 dwellings, 81% of them flats and 19% houses, built 25% before 1919, 7% between 1919 and 1939 and 64% after 1945.

Southwark works hours and getting materials into a block

Southwark's noisy works hours set the outer limit inside a block: 8am to 6pm on weekdays and 9am to 2pm on Saturday, with nothing on Sundays or bank holidays. In a block shared with other households, the loud jobs such as lifting old tiles, breaking out a screed or chasing walls for a rewire need careful timing. The managing agent may also ask you to tell the neighbours in writing in advance.

Deliveries are the other constraint. In a converted Victorian house or a low-rise estate block there may be no lift, so plasterboard, worktops and a bath go up the stairs by hand. Where a lorry needs a bay outside, Southwark needs seven days notice for a parking bay suspension, and charges a non-refundable admin fee plus a daily charge per car space. We book it for the days when the heavy items arrive, not the whole job.

Hard floors, leaks and sound in a Southwark flat

Swapping carpet for timber or tiles is the change most likely to cause a dispute in a Southwark block, so check the lease before you choose the floor. Many leases require carpet or an acoustic underlay in upper flats, and some managing agents ask for the product sheet before approval. An acoustic mat under an engineered board or a floating floor keeps footfall noise away from the flat below and keeps you within the lease.

Kitchen and bathroom renewals inside the flat footprint carry a second risk: water. A leak through the floor reaches the flat below, so we pressure test new pipework before it is boxed in, tank the shower area and fit isolation valves where they can be reached. The consumer unit and circuits are renewed by a registered electrician who certifies the work, and a registered gas engineer handles any boiler or gas pipe; flats without gas get electric heating instead.

Letting a refurbished Southwark flat and the EPC floor

If you let the flat, it needs an EPC rating of E or better unless a valid exemption applies. Southwark states it is illegal for a domestic landlord to let a property with an EPC rating of F or G. National guidance adds that since 1 April 2020 landlords cannot let or continue to let a property covered by the MEES Regulations below E without a valid exemption, so the rule reaches existing tenancies as well as new ones.

Between tenancies that changes the specification. Draught stripping, better heating controls, efficient electric heaters or a new boiler, and secondary glazing where the frames must stay are the usual ways to lift a flat's rating. Southwark also charges a fee for selective licences of privately rented homes, so check with the council whether your flat needs one and what property conditions it carries. We schedule the energy work while the flat is empty so your assessor can issue the new certificate before the next tenant moves in.

• Bathroom and shower room renewal with pressure tested pipework
• Electric heating upgrades: high retention heaters, or a heat pump where the building allows
• Unvented cylinder replacement, notified to building control

Why Southwark Homeowners Choose GS Renovation

A flat refurbishment is judged by the neighbours as much as by you, and we plan for that from day one. We work to the managing agent's rules and the licence to alter, protect the common parts, keep the loud work inside the permitted hours and take waste out as agreed. Inside the flat we run the trades as one sequence, pressure test pipework before it is hidden and hand over with the electrical and gas certificates.

• Deliveries timed around the lift, the stairs and the parking rules of the block
• Free follow-up visit after completion if anything needs attention
• New pipework pressure tested so nothing leaks into the flat below
