Flat refurbishment in New Cross covers the most common home in the area: the VOA count for New Cross Gate, New Cross South and Telegraph Hill puts 72% of homes there as flats. That takes in a floor of a converted Victorian terrace, a flat in a post-war block and a newer flat, since 16% of homes in that count date from 2000 or later. Each sits inside a building shared with neighbours, under a lease, so the work is planned around the freeholder, the managing agent and the flat below as much as around the rooms themselves.
For New Cross, 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 Cross: 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.

Leasehold flats in New Cross and the paperwork before work starts
Most New Cross homes are flats, so a refurbishment here is often inside a building shared with other households, and for an owned flat that means a lease. Your lease decides what you may change, and a licence to alter from the landlord or managing agent normally comes before any wall, floor finish or bathroom moves. Managing agents may set their own working hours and ask for a method statement, a named site contact and delivery times before the first van arrives.
We prepare that pack for you: the scope, the programme, how common parts will be protected and who to call on site. Some blocks limit noisy work more tightly than the council does, and the block's rules then set the day. Where the building is in a conservation area, Lewisham says flats and subdivided houses have no permitted development rights, so new windows or anything else that changes the outside of a New Cross flat needs planning permission first.
Housing in New Cross
Around 12,080 homes make up New Cross on the valuation list; 72% are flats and 28% houses, and 43% date from before 1919, 2% from between the wars and 49% from after 1945.
Converted terraces, post-war blocks and newer New Cross flats
The kind of block shapes the job. New Cross housing is largely Victorian terraces and post-war infill. With 43% of homes in the wider VOA count built before 1919, the flat you are refurbishing may well be a floor of a converted house. Those have timber floors that carry sound, shared lofts and pipework that crosses between flats. A post-war block, from the 49% of that count built after 1945, has concrete floors, risers owned by the freeholder and a managing agent who controls access to them.
Newer flats, the 16% of that count built in 2000 or later, bring their own limits: fire-stopped service routes that must not be broken, sprinkler or alarm heads in the ceilings, and warranty or building rules on what may be cut. In a higher-risk building, a taller residential block, the Building Safety Act can make the Building Safety Regulator the building control body. Work under a competent person scheme needs no Regulator approval. The accountable person will want to see the proposal. We confirm which regime applies before any drawings are priced.
Kitchens, bathrooms, floors and the flat below in New Cross
Inside a New Cross flat the work stays within your own footprint: a new kitchen, a new bathroom, a rewire from a new consumer unit, and heating by boiler or electric panels depending on what the block allows. Lewisham says a building control inspection is needed whenever a WC or bath is installed or moved to a new position, and a new bathroom has its own inspection. A registered electrician certifies the wiring, and a registered gas engineer connects any boiler.
The flat below is the neighbour most affected. Your lease may require an acoustic layer beneath hard floors laid over a neighbour's ceiling, and we agree the build-up with the managing agent before tiles or boards go down. Wet rooms are tanked and tested before tiling, and we check old waste and supply joints when the bath comes out, because a leak into the ceiling below damages a home that is not yours. Common parts and the lift are covered for the whole job.
Letting a New Cross flat: EPC ratings and selective licensing
A New Cross landlord refurbishing a flat between tenancies has two sets of rules to build to. GOV.UK guidance means that, since 1 April 2020, a property covered by the MEES Regulations cannot be let, or kept let, with an EPC rating below E unless a valid exemption applies. New tenancies on F or G rated homes have been barred since 1 April 2018. In a flat the usual moves are better heating controls, a more efficient boiler or heaters, draught-proofing and lighting, and we sequence them before decoration.
Lewisham's selective licensing scheme came into effect on 1 July 2024 and covers around 20,000 properties. Check whether a rented flat is inside the designated area, as it may need a licence as well as a sound EPC. The landlord or their agent makes the application, and the licence or a Lewisham inspection can produce a list of repairs. We work through that list between tenants, then give you dated invoices and photographs of the finished work to keep with the licence file.
- Consumer unit replacement from the meter onwards
- Common parts protection: floor sheeting, corner guards and lift lining
- Unvented cylinder replacement, notified to building control

FAQ
Frequently Asked Questions about Flat Refurbishment New Cross
Why do flat refurbishment quotes in New Cross 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 Cross price. Compare quotes line by line.
Does a leaseholder need the freeholder's consent to refurbish a New Cross flat?
Usually yes, for anything beyond decoration. Your lease sets what you may change, and a licence to alter from the landlord or managing agent normally comes before walls, floors or a bathroom are moved. Agents may ask for drawings, a method statement and a site contact. We prepare the builder's part of that pack so the licence is not held up.
Can a landlord let a New Cross flat with an F rated EPC?
Not without a valid exemption. GOV.UK guidance means that since 1 April 2018 a new tenancy cannot start on an F or G rated home, and since 1 April 2020 a property covered by the MEES Regulations cannot be let at all below E without an exemption. We carry out the heating, insulation and controls works your assessor recommends, and the assessor then lodges the new EPC.
Does selective licensing cover rented flats in New Cross?
Possibly. Lewisham's selective licensing scheme came into effect on 1 July 2024 and covers around 20,000 properties in the borough, so check whether your address is in the designated area before letting. The landlord or agent makes the application. Where a licence inspection lists repairs, we carry them out in a set order and give you a dated record for the file.
Can the windows of a flat in a New Cross conservation area be changed?
Only with planning permission. Lewisham says flats or subdivided houses in conservation areas have no permitted development rights and must seek planning permission for changes to the exterior. Your lease may also reserve the windows to the freeholder. Your designer or agent applies, and we fit the approved windows once both consents are in place.
Does a new wooden floor in a flat need sound insulation beneath it?
Often, because many leases require it. A hard floor laid over a neighbour's ceiling can carry footfall noise, so leases commonly ask for carpet or an acoustic underlay or batten system. We agree the build-up with the managing agent before the floor is ordered and allow for the extra height at door thresholds.
Does moving the bathroom in a New Cross flat need building control?
Yes. Lewisham says a building control inspection is needed when a WC or bath is installed or moved to a new position, and a new bathroom is on its charges list in its own right. In a flat the waste route to the stack decides where a WC can go, so we check falls and the stack connection before your layout is fixed.
How do you get materials into an upper-floor New Cross flat?
By planning the route before the first delivery. We book the lift or stair with the managing agent, protect the entrance, landings and lift car, and bring boards and fittings up in sizes that turn the stair. Waste goes down in bags on the same agreed route, so the common parts are never left blocked, and anything too long for the lift is measured before it is ordered.
What happens if work in a flat causes a leak into the one below?
We aim to prevent it first. Supply and waste joints are checked when old fittings come out, new pipework is pressure tested before floors close, and wet areas are tanked and left to cure before tiling. If water does escape, we isolate it at once, tell the neighbour and the managing agent, and put right the joint or fitting that failed.
