Flat refurbishment in New Malden serves the minority of the stock: 31% of homes here are flats against 69% houses. A flat here can be a floor of a converted Victorian house or part of a purpose-built block, and 9% of all homes were built in 2000 or later. Whatever the building, a flat is refurbished inside a shared structure: the lease, the managing agent, the neighbours below and the block's rules shape the programme as much as the kitchen and bathroom do.
For New Malden, 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 New Malden: 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 and licences for a New Malden flat
31% of homes in New Malden are flats, and refurbishing one brings the lease into the programme. Check it for three things: whether alterations need the landlord's written licence, the permitted working hours, and how floors must be finished to limit noise to the flat below. We read those clauses with you before ordering materials, because a hard floor may need an acoustic underlay the lease names. The managing agent may want a method statement and programme before the first day, so we send them ahead to avoid a stop on site.
A licence to alter is usually needed for anything beyond decoration: moving a kitchen, forming a new shower room, or changing the floor finish. The freeholder may ask for drawings and a copy of the building control approval before signing. Allow for that in your start date, because the licence can take longer than the building work to arrange. We supply the scope, method statement and programme the freeholder asks for, alongside any drawings from your designer, and start once the licence is signed, not before.
Housing in New Malden

Working inside a block in New Malden without upsetting neighbours
A flat refurbishment in New Malden shares a staircase, a front door and often a bin store with other residents. We protect common parts with floor and wall coverings on the route from the entrance to the flat, and we agree with the managing agent where materials can be stacked. A converted house rarely has a lift, so plasterboard, kitchen units and sanitaryware are carried up the stairs by hand and the delivery is split into loads that fit the landing.
Noise is the other shared cost. Stripping out tiles, chasing walls and lifting floors are the loud days, and we give neighbours notice of them in advance and keep them inside the hours the lease or block rules allow. Leaks into the flat below are the main risk during a bathroom or kitchen renewal, so the water is isolated before pipework is cut. New joints are pressure tested before the floor goes down, and any old waste pipe running under the floor is checked while it is exposed.
Letting a New Malden flat under the energy efficiency rules
If you let a flat in New Malden, the refurbishment has to leave it lettable under the minimum energy efficiency standard. New tenancies have been barred at F or G since 1 April 2018. Since 1 April 2020 landlords cannot let or continue to let a property covered by the rules with an EPC rating below E without a valid exemption. Kingston enforces this and can fine a private landlord who does not meet the standard, so the void between tenancies is the moment to act.
In a flat, the measures that move an EPC sit inside your own walls: heating controls, a newer boiler or efficient electric heating, draught-proofing, better glazing where the lease lets you change windows, and insulation to any wall or floor you own. Kingston says historic, listed or conservation area buildings are exempt only where compliance would unacceptably alter their character or appearance. We agree the measures with your energy assessor before stripping out, so the refurbishment and the new certificate point the same way.
Building control for a new bathroom in a New Malden flat
Where the work needs building regulations approval, such as forming a new bathroom or WC, and Kingston is the building control body, its inspectors attend Monday to Friday, typically between 9.30am and 3pm. We book each stage visit so the next trade is ready once the officer has seen the work, which keeps a flat refurbishment from standing idle between inspections. A like-for-like bathroom in the same place usually needs no application, but a new one in a new room does.
After a satisfactory final inspection Kingston issues the completion certificate within 5 working days, the document you will need when the New Malden flat is sold or remortgaged. We pass it to you with the electrical certificate for the new consumer unit and circuits, issued by the registered electrician, and the gas paperwork where a boiler has been replaced. Keep them together with the licence to alter, because a buyer's solicitor will ask for all three.

We read the lease and block rules with you first, send the managing agent a method statement and programme, and protect the common parts before the first delivery. One site manager runs the job and is the contact for neighbours. You get a written quotation after a survey, a written programme with the loud days marked, and the certificates from the registered trades at handover.

FAQ
Frequently Asked Questions about Flat Refurbishment New Malden
Why do flat refurbishment quotes in New Malden vary?
They rarely price the same work. One includes acoustic underlay to the lease specification, protection of the common parts and the electrician's certificate; another treats them as extras. Published UK averages of £33,000 to £48,000 for a full flat refurbishment (Checkatrade and MyJobQuote, 2026) are a starting point, not a New Malden price. Compare quotes line by line.
How many homes in New Malden are flats?
31% of homes in New Malden are flats and 69% are houses. A flat can be a floor of a converted house or part of a purpose-built block. Each type brings its own rules on access, noise and alterations, set by the lease and the freeholder or managing agent rather than by the council.
Do you need the freeholder's consent to refurbish a New Malden flat?
Often yes. Check whether your lease requires a written licence to alter before structural work, moving a kitchen or bathroom, or changing floor finishes. Read your lease first, then ask the managing agent what they need. We provide the scope, method statement and programme for the application, and start once the licence is signed.
Can a New Malden landlord let a flat with an F rated EPC?
Not without a valid exemption. Since 1 April 2020 landlords cannot let or continue to let a property covered by the energy rules with an EPC rating below E. Kingston can fine a private landlord who does not meet the standard, so the refurbishment between tenancies is the time to upgrade the heating, glazing and insulation.
Why does a lease ask for acoustic underlay under a hard floor?
Because a timber or tiled floor carries footfall noise into the flat below far more than carpet does. A lease may require carpet or an approved acoustic layer, and some managing agents want to see the product before it goes down. We check the clause and price the build-up it asks for.
When do Kingston inspectors visit a New Malden flat refurbishment?
Where Kingston is the building control body, inspections are available Monday to Friday, except public holidays, with an officer typically attending between 9.30am and 3pm. We book each visit in advance so the work stays open for inspection and the next trade can follow once the stage is passed.
Who is responsible for the flat entrance door and fire safety in a block?
The lease decides who owns the flat entrance door, and the responsible person for the building has duties under fire safety law for the common parts and the fire separation around them. Do not change the entrance door or cut into a compartment wall without checking. We work to whatever the freeholder specifies for fire-rated items.
How long does a completion certificate take for a New Malden flat?
Kingston issues the completion certificate within 5 working days of a satisfactory final inspection. That certificate, the electrical certificate and the gas paperwork are what a buyer's solicitor asks for, so we collect them and hand them to you together at the end of the job.
Is an older converted flat in New Malden exempt from the energy rules?
Only in narrow cases. Kingston says historic, listed or conservation area buildings are exempt where meeting the standard would unacceptably alter their character or appearance. The landlord registers any exemption, so confirm with your energy assessor whether it applies before the works are scoped around it.
