What are you renovating?
A homeowner on Dundonald Road SW19 submitted a brief for a rear single-storey extension and kitchen refurbishment in the spring of 2023. They had already received two quotes: one from a contractor who had knocked on the door, one from a local firm their neighbour had used three years earlier for a different scope of work. The quotes were £46,000 apart.
The lower quote excluded the structural engineer’s fee, the party wall surveyor, building regulations, and the Planning Portal fee, all of which the project required. The higher quote was all-in. When the homeowner priced the lower quote properly, the gap closed to £8,000. They found a third contractor through QuoteMyRenovation, vetted, with three completed rear extension projects in SW19 in the previous twelve months, whose all-in quote came in £4,000 below the adjusted higher figure.
Getting the right price on a Wimbledon renovation is not straightforward. The SW19 market is active, the housing stock is varied: Victorian terraces in South Wimbledon, larger Edwardian semis around Wimbledon Park, substantial detached houses near the Village and the planning environment in the London Borough of Merton includes conservation area designations that affect what can be built and how.
QuoteMyRenovation sends your brief to vetted Wimbledon contractors who know the LB Merton planning environment, quote in the same format, and compete on quality and price, not on what they leave out.
Renovation in Wimbledon SW19: What Homeowners Are Working With
SW19 covers a wider area than the Wimbledon town centre and the All England Club suggest. The postcode district takes in South Wimbledon, Wimbledon Chase, Wimbledon Park, and the edges of Raynes Park to the south: a stretch of housing that ranges from Victorian and Edwardian terrace streets around Haydons Road and Merton Road to the larger Edwardian semis and detached houses of Wimbledon Park Road and Arthur Road, and the premium detached Victorian villas of Wimbledon Village.
The renovation scope that makes sense for each housing type is different.
South Wimbledon and the terrace streets (SW19 1, SW19 2)
Victorian mid-terraces of two and three bedrooms, typically on narrow plots with rear gardens of twelve to eighteen metres. The most common renovation brief here is a rear single-storey extension to open up the kitchen-diner, a loft conversion to add a bedroom at roof level, or both on the same contract. The party wall process applies on both sides; the planning picture varies by street. London Borough of Merton should be checked for Article 4 Directions and conservation area designations before drawings are commissioned on any terrace street in this part of SW19.
Wimbledon Park and Wimbledon Chase (SW19 5, SW19 7)
Predominantly Edwardian semis and inter-war detached houses on wider plots. The typical renovation brief here is larger: rear two-storey or wraparound extension, loft conversion with hip-to-gable or L-shaped dormer, and full internal refurbishment. Plot widths allow for more ambitious side extensions than the terrace streets to the south. A party wall applies on the shared side with the adjoining semi; loft conversions often engage the party wall at eaves level.
Wimbledon Village (SW19 5, The Conservation Area)
Victorian and Edwardian villas and substantial detached houses. The planning environment here is the most constrained in SW19: the Wimbledon Village conservation area covers the hilltop and its surrounding streets, imposing strict controls on external materials, roof alterations, and front elevation changes. Permitted Development rights for roof extensions are removed. Full planning permission is required for most structural external alterations. Pre-application advice from LB Merton planning is advisable on any scheme in the Village.
The most requested renovation in SW19. On a terrace or semi-detached house, a rear extension of 3 to 6 metres replaces or extends the narrow back addition, creating the kitchen-diner space that modern living in a Victorian or Edwardian house requires. LB Merton planning and Permitted Development rules apply; Article 4 Direction coverage should be checked by street. Party wall notices are required on both adjoining owners for a terrace, on one side for a semi.
Wimbledon’s Edwardian semis are particularly well suited to hip-to-gable loft conversions: the hip end of the roof is converted to a gable, and a rear dormer is added, creating a full floor of additional accommodation. On a Victorian terrace, a rear dormer is the more common form. In the conservation area, front dormers require full planning permission; rear dormers may require it depending on the specific street and Article 4 status.
On the wider-plot semis and detached houses of Wimbledon Park, a two-storey rear extension adds a ground-floor kitchen-dining space and a first-floor bedroom or bathroom above, without the planning complexity of a side extension. On a semi-detached property, the party wall at the rear boundary and on the shared side both need to be assessed.
Wimbledon’s Edwardian housing stock benefits in particular from whole-house refurbishment programmes: rewiring, new central heating, new bathrooms, replastering, and structural alterations under a single contract. Managing these works on a sequential programme reduces abortive work and keeps the house habitable for as long as possible during construction.
London Borough of Merton is the local planning authority for SW19. Householder planning applications are submitted via the Planning Portal and determined by LB Merton’s planning team, with an eight-week statutory determination period from validation.
Permitted Development in LB Merton follows the national framework: rear extensions of up to 3 metres on a terraced or semi-detached house (or up to 6 metres under Prior Approval) are generally Permitted Development on houses where rights have not been removed. However, LB Merton has designated multiple conservation areas within the borough, and some streets carry Article 4 Directions that remove specific PD rights. The Wimbledon Village conservation area in particular imposes significant constraints beyond standard PD removal of PD rights for roof extensions, cladding, and front elevation alterations.
Before commissioning any drawings, check the LB Merton planning portal for:
- Whether your property is within a conservation area boundary (and which one)
- Whether an Article 4 Direction affects your street or property type
- Whether your property is listed or within the curtilage of a listed building
On properties within the conservation area, pre-application advice from LB Merton planning is strongly recommended before committing to a design. The planning officer’s pre-application response will identify any issues with massing, materials, or roofline that would otherwise result in a refused application.

The Wimbledon Village Conservation Area
The Wimbledon Village conservation area covers the hilltop historic core of Wimbledon: the High Street, Church Road, and the surrounding streets of Victorian and Edwardian villas. It is one of the most tightly managed planning environments in LB Merton.
Within the conservation area, Permitted Development rights are more restricted than in the wider borough. In particular:
- Roof extensions (including rear dormers) that alter the roofline or are visible from a public highway require full planning permission – they are not Permitted Development within the conservation area.
- External cladding, rendering, and stone facing on any elevation visible from a highway require planning permission.
- Alterations to front elevations – including window replacements that change the type of window require planning permission.
- Demolition of structures over a certain size within the conservation area requires conservation area consent.
Materials in the conservation area are controlled. LB Merton typically requires new extensions to be built in matching or complementary materials to the host building, which in the Village means stock brick, natural slate, and timber windows rather than render, concrete tiles, and aluminium frames.
Contractors working in the Wimbledon Village conservation area need to be familiar with LB Merton’s design guidance for the area, the local materials palette, and the planning officer’s expectations. A contractor who quotes without reading the conservation area appraisal is not the right contractor for a Village project.
What Does a Renovation Cost in Wimbledon SW19?
Wimbledon renovation costs track the broader south-west London market higher than outer London averages, but below the premium levels of Chelsea, Kensington, or Hampstead. The SW19 market is competitive, with a reasonable density of experienced residential contractors.
| Renovation Scope — Wimbledon SW19 | From | To | Notes |
|---|---|---|---|
| Rear single-storey extension (terrace or semi, 6–15 m²) | £65,000 | £130,000 | Structure, glazing, roof, finishes, building regulations; excludes kitchen fit-out and party wall surveyor fees; higher end for full-width glazed roof or lantern and bifolds |

| Full gut refurbishment — 3-bed house (no extension) | £100,000 | £185,000 | Rewire, new central heating, 1–2 bathrooms, kitchen fit-out, replastering, decoration; London mid-range specification; Wimbledon Village conservation area projects typically 10–20% higher |
| Kitchen renovation (supply and fit, mid-range specification) | £20,000 | £50,000 | Units, worktops, appliances, splashback, plumbing and electrical connections; excludes structural works; bespoke or luxury specification at upper end and above |
| Bathroom renovation (per bathroom, mid-range specification) | £8,000 | £22,000 | Strip out, new sanitary ware, tiling, plumbing, waterproofing, decoration; family bathroom at lower end; large en-suite with bespoke tiling at upper end |
| Full rewire — 3-bed Victorian or Edwardian house | £8,000 | £18,000 | Consumer unit, all circuits, sockets, lighting; done before plaster finishes during a full refurbishment; higher end includes smart lighting and underfloor heating wiring |
| Total — rear extension + loft conversion + full refurbishment, Wimbledon | £220,000 | £400,000 | All-in estimate for a combined programme on a typical Wimbledon three-bedroom house; excludes party wall surveyor fees (£2,000–£14,000), planning fees, and professional fees (architect, structural engineer) |
All costs are approximate SW19 / LB Merton ranges (2024–2025). Projects within the Wimbledon Village conservation area typically cost 10–20% more due to materials requirements and additional planning conditions. Costs exclude party wall surveyor fees, planning application fees, and professional fees. Always obtain written fixed-price quotes from at least three vetted contractors before committing.
Getting like-for-like quotes in Wimbledon requires a clear schedule of works a document that specifies exactly what is included, what is excluded, what allowances are made for fixtures and fittings, and who is responsible for the structural engineer, party wall surveyor, and planning fees. A quote without this information cannot be compared to another quote that includes it.
QuoteMyRenovation provides all three matched contractors with the same brief, so the quotes they return can be compared on the same basis.
Why the Right Contractor Matters in Wimbledon
The SW19 renovation market includes a wide range of contractors, from sole traders operating on price to established residential firms with dedicated project management. The gap between a good Wimbledon renovation contractor and a poor one is not primarily measured in price at the tender stage. It is measured in:
Programme Management
A Wimbledon renovation on a lived-in family home requires a contractor who manages the sequence of trades structural works, mechanical and electrical first-fix, plaster, second-fix to keep the programme moving and the disruption to the household manageable. A contractor who loses a week to a sequencing error affects not just the programme but the family living through the works.
LB Merton planning Familiarity
Contractors who have completed multiple projects in SW19 know the LB Merton planning officers, the conservation area constraints, the Article 4 streets, and the borough’s standard conditions and material requirements. This knowledge prevents avoidable planning delays and rejected details.
Party wall Experience
SW19’s terrace and semi-detached streets mean party wall obligations on almost every structural project. A contractor who manages the notice process from the brief stage, rather than leaving it to the homeowner to discover after appointment, demonstrates competence and protects the programme.
Subcontractor Relationships
The best Wimbledon renovation contractors have established relationships with reliable local subcontractors, structural engineers, electricians, plumbers, and tilers whom they have worked with repeatedly and whose quality they can vouch for. A contractor who introduces a new subcontractor to every project carries subcontractor quality risk that an established team does not.
