This guide focuses on the decisions that determine a Westminster 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 Westminster flat refurbishment page.
Start with the local service context
For a flat in Westminster, read the lease and identify the landlord or managing agent before agreeing alterations. Written consent or a Licence to Alter is required where the lease and proposed work call for it; do not assume the same requirements for every building. Check shared floors, walls, service routes and access conditions. Planning and listed-building requirements are separate checks with Westminster.
Who has to approve a flat refurbishment in Westminster SW1?
For a flat in Westminster, read the lease and identify the landlord or managing agent before agreeing alterations. Written consent or a Licence to Alter is required where the lease and proposed work call for it; do not assume the same requirements for every building. Check shared floors, walls, service routes and access conditions. Planning and listed-building requirements are separate checks with Westminster.
Do conservation rules affect an interior flat refurbishment in Westminster?
Check the address and proposed work with Westminster. Confirm the conservation-area boundary, any Article 4 direction and whether the building is listed. Listed-building consent may be required for alterations affecting its special interest, including internal work. An Article 4 direction applies to specified properties and types of development; it does not make every refurbishment a planning application. Assess Building Regulations and any lease or estate consent separately.
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 Westminster brief. They do not replace property-specific advice or a current consent check.

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.
