This guide focuses on the decisions that determine a Chelsea flat refurbishment: defining the work, checking property and consent constraints, setting an evidence-backed budget and planning the sequence. The detailed local service scope remains on the Chelsea flat refurbishment page.
Start with the local service context
For a flat in Chelsea, check the lease and alteration requirements with the landlord or managing agent. The lease and proposed work determine whether written consent or a Licence to Alter is needed. Establish the shared structure, floor build-up, service routes and access arrangements before agreeing alterations. Planning, listed-building and Building Regulations checks are separate; a postcode does not establish which approvals apply.

What range of flats do you refurbish in Chelsea?
Everything the area offers. Chelsea runs from the riverside houses of Cheyne Walk and Tite Street, through the Georgian and Victorian streets off the King's Road, to the red-brick mansions of Cadogan Square — a mix of listed townhouses and prime leasehold flats — and each building type brings its own refurbishment logic, which is where our design work starts.
Define the work before comparing prices
Record the existing layout and services, then separate essential fabric and compliance work from layout changes, fitted joinery and finishes. For a leasehold flat, place freeholder, managing-agent and Licence-to-Alter requirements on the decision list before design is fixed.
Check the recorded local constraints
These cited records identify issues to verify for a Chelsea brief. They do not replace property-specific advice or a current consent check.
- Chelsea’s streets fall across several conservation areas on RBKC’s register — the Chelsea, Chelsea Park Carlyle, Cheyne, Royal Hospital and Sloane Square conservation areas are all listed — so most external work in SW3 is assessed against conservation-area tests.Source: RBKC conservation area maps (register of the borough's conservation areas)
- The Cadogan Estate consents much of the land; flats need a Licence to Alter.Source: Cadogan Estates - residential customer guidance on alterations and Licence to Alter
- RBKC Article 4 directions withdraw permitted development rights for small-scale external changes — replacing windows and front doors, removing or rebuilding boundary walls, roof coverings and other front-elevation works — at properties listed on Chelsea streets including Cadogan Square, Carlyle Square, Chelsea Park Gardens, Chelsea Square, Glebe Place and the King’s Road, so those works need planning permission.Source: RBKC - Article 4 Directions in Conservation Areas (register of directions by street)
Use the approved budget ranges consistently
The approved flat range is based on a full two-bedroom refurbishment. Keep that basis visible when comparing it with a project-specific scope.
| Scope basis | Guide rate | Typical total | Programme |
|---|---|---|---|
| Full two-bedroom flat refurbishment | £900–£1,700/sqm | £60,000–£110,000 | 16–32 weeks |
These are planning ranges, not a quotation. The property survey, final scope, specification, access and consent requirements determine the project-specific cost and programme.
Build the brief in a practical order
- Confirm the measured area, retained rooms and every proposed structural or services change.
- Check the lease, freeholder and managing-agent requirements before committing to a layout.
- Confirm whether planning permission, listed-building consent or building-control approval applies.
- Price one written scope so exclusions, provisional sums and finish allowances can be compared.
- Plan access, deliveries, working hours and neighbour communication for the specific building.
