Flat Refurbishment Wandsworth

Flat refurbishments in Wandsworth, your flat renewed within the lease, the licence and the rules of the block.

Flats are the larger part of Wandsworth's housing: 72% of the borough's homes are flats. They range from mansion blocks and converted Victorian houses to riverside developments, and 21% of all homes were built in 2000 or later. Each flat sits inside a building shared with neighbours, so the lease, the managing agent's rules, the stairs and the flat below shape the job as much as the kitchen or bathroom being renewed.

For Wandsworth, 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 Wandsworth: 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, licences to alter and managing agents in Wandsworth blocks

72% of Wandsworth homes are flats, from mansion blocks to newer riverside developments, so a refurbishment here often starts with the lease rather than the tools. The lease sets which works need the landlord's consent, and a licence to alter gives it: moving a kitchen, lifting floorboards, altering a bathroom over someone else's ceiling. The managing agent sets working hours, lift protection and where waste leaves the building, and those rules decide how many days the job takes.

The kind of block changes the paperwork. A Wandsworth mansion flat may come with an older lease, a porter and a managing agent who wants method statements before work starts. A flat in a converted Victorian house may have a freeholder living upstairs and no agent at all. In the newer blocks, including riverside developments, the building manager can ask for contractor documents, an induction and booked lift slots. We read the lease clauses with you before pricing, so the programme fits the rules.

Housing in Wandsworth

Around 157,900 homes make up Wandsworth on the valuation list; 72% are flats and 28% houses, and 43% date from before 1919, 7% from between the wars and 49% from after 1945.

Hard floors, leaks and the flat below in a Wandsworth block

Floors are the usual point of friction in a Wandsworth block. Swapping carpet for timber or tile can make impact noise worse for the flat below, and a lease may require an acoustic underlay or a floor build-up that meets a stated standard. We agree that build-up with the agent before ordering the finish, because a floor that fails the lease has to come up again, and the neighbour below is then disturbed twice.

Kitchens and bathrooms are renewed inside the flat's existing footprint, because a lease can forbid moving wet rooms over a neighbour's bedroom. Before the old bath comes out we find the stopcock, isolate the flat and check the waste runs, since a failed joint in a Wandsworth mansion block can show up two floors down. New showers get a tanked floor and walls, and the pipework is pressure tested before any tiling. If a leak is found from earlier work, we report it to you and the agent straight away.

Fire safety, planning and building control inside a Wandsworth block

Inside a Wandsworth block, fire safety runs across the flat boundary. The flat entrance door and the compartment walls and floors protect the whole building, so changes to them are a matter for the freeholder or the responsible person as well as you. We keep the entrance door's fire rating, re-seal any holes we make in compartment walls, and do not cut new openings through them. Any fire-stopping we disturb around pipes and cables is made good before the ceiling or boxing closes over it.

Planning bites on the outside of the flat. Wandsworth's conservation area guidance states that permitted development rights do not apply to flats or houses converted to flats, so an external change that materially alters the building's appearance, such as new windows of a different design, needs planning permission. In a higher-risk building under the Building Safety Act, the Building Safety Regulator is the building control authority for relevant work, and the agent will say whether the block falls in that regime.

Letting a refurbished Wandsworth flat: EPC, MEES and licensing

A landlord refurbishing a Wandsworth flat between tenancies needs the finished flat to clear the minimum energy standard. Since 1 April 2020 landlords can no longer let or continue to let properties covered by the MEES Regulations with an EPC rating below E without a valid exemption, and local authorities enforce the rules. In a flat, the rating moves with the heating system, hot water, glazing and lighting, so electric panel heaters or an old boiler are the first things an assessor looks at.

Specifying for E alone can mean reopening the flat within a few years. The government has confirmed plans to raise the minimum for private lets to EPC C, subject to regulations, so a Wandsworth refurbishment done now should aim for C where the cost is reasonable. Licensing is the second check: since 1 July 2025 Wandsworth's additional HMO licensing has covered HMOs outside mandatory licensing, so a flat let to sharers needs the landlord to confirm its licence before they move in. We hand over the electrical certificate, gas safety paperwork and the records of each energy measure for the new EPC.

The GS Renovation Difference in Wandsworth

A flat refurbishment is decided by the building's rules as much as by the work, so we read the lease and the agent's conditions before we price. Our own trades carry the strip-out, kitchen and bathroom renewal, floors and decoration, working to the block's hours and booked lift slots. A registered electrician renews the consumer unit and certifies the wiring, and a registered gas engineer does any boiler work. Neighbours are told the noisy days in advance, and common parts are protected from the first day.

  • The lease and licence to alter read before a flat is quoted
  • Deliveries timed around the lift, the stairs and the parking rules of the block
  • Site left safe and secure at the end of every day

FAQ

Frequently Asked Questions about Flat Refurbishment Wandsworth

How much does a flat refurbishment cost in Wandsworth?

Published UK averages put a full flat refurbishment at £33,000 to £48,000 and a basic one at £15,000 to £18,000 (Checkatrade and MyJobQuote, 2026), and London flats usually cost more. In a Wandsworth block the building adds its own lines: protecting the common parts, carrying materials up, working in the managing agent's hours and meeting the lease's floor rules. The quote after the survey itemises each one.

Does a Wandsworth leasehold flat need a licence to alter before refurbishment?

Yes, for anything the lease reserves to the landlord. A lease can require consent to alter the layout, lift floors, move plumbing or change the electrics, and a licence to alter records that consent. Ask the managing agent early, because the licence may come with conditions on hours, floor build-ups and a surveyor's inspection that change the programme.

Can a landlord let a Wandsworth flat with an F-rated EPC after refurbishment?

No, not without a valid exemption. Since 1 April 2018 private landlords may not let domestic properties on new tenancies if the EPC rating is F or G, and since 1 April 2020 that applies to continuing lets below E as well. The government has confirmed plans to raise the minimum to C, subject to regulations, so aim for C while walls and floors are open, where the cost is reasonable.

Does a rented flat in Wandsworth need a property licence after refurbishment?

It does if it is let to three or more people from two or more households. Since 1 July 2025 Wandsworth's additional HMO licensing has covered HMOs not already under mandatory licensing, and a shared flat is one. A flat let to one household needs a selective licence only if its address falls inside a selective licensing designation, and Wandsworth says each flat in a converted block would then need its own. The landlord applies; we build to the conditions.

Can a Wandsworth flat get new windows without planning permission?

Usually not, outside a listed building. Flats have no householder permitted development rights, so a window change that materially alters the outside needs planning permission, while replacing windows with matching ones does not. In a listed building, any replacement, even a matching one, normally needs listed building consent, so ask the council before ordering. Wandsworth's conservation area guidance makes the same planning point about flats and converted houses. Agree the design with the freeholder first.

How do materials reach an upper floor in a Wandsworth mansion block?

By the route the agent approves. Mansion blocks and riverside developments in Wandsworth each have their own rules on lift use, protection and delivery times. We book lift slots, line the lift car and the stair, carry plasterboard and tiles in manageable loads, and take waste out in bags on the same route rather than leaving it in common parts.

Who is responsible for the flat front door in a block?

The flat entrance door is part of the building's fire protection, so the freeholder or responsible person has a say in it even if the lease makes it yours. Replace it only with a door and frame of the required fire rating, fitted with a closer and seals, and agree the specification with the agent first.

Does work to the common parts of a Wandsworth block need full plans?

Yes, in practice. A building notice cannot be used for a building where the fire safety order applies, and in a block it applies to the common parts, so work there goes to Wandsworth Building Control as a full plans application. The council takes 40% of the charge on application and invoices the 60% inspection charge after the first site visit. Work to the landing, stair or entrance door also needs the freeholder's consent first.

How do you stop a new bathroom leaking into the flat below?

By testing before anything is covered. We tank the shower area, pressure test the new supply pipes, check each waste joint with water running, and only then tile and box in. Access panels go where valves and traps sit, so a future fault can be reached without breaking tiles or the ceiling below.
