This guide focuses on the decisions that determine a Mayfair 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 Mayfair flat refurbishment page.

Start with the local service context

For a flat in Mayfair, 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.

What defines a flat refurbishment on Mount Street or South Audley Street in Mayfair?

Coordinate the retained interior, proposed layout and shared building services. Establish the lease and any applicable estate requirements for the actual property, and assess planning and listed-building consent separately. These checks inform the drawings and scope before work is programmed.

Is refurbishing a Mayfair flat mostly a consent exercise?

The design and construction scope matters alongside the consent checks. Plan the layout, retained features, services and finishes, then assess any planning, listed-building or lease requirements for those alterations. The applicable approvals, building condition and procurement lead times together inform the programme.

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 Mayfair 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.

Approved refurbishment planning ranges
Scope basisGuide rateTypical totalProgramme
Full two-bedroom flat refurbishment£900–£1,700/sqm£60,000–£110,00016–32 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

  1. Confirm the measured area, retained rooms and every proposed structural or services change.
  2. Check the lease, freeholder and managing-agent requirements before committing to a layout.
  3. Confirm whether planning permission, listed-building consent or building-control approval applies.
  4. Price one written scope so exclusions, provisional sums and finish allowances can be compared.
  5. Plan access, deliveries, working hours and neighbour communication for the specific building.
