Why it matters
Need a chartered surveyor or valuer in Belgravia or Knightsbridge?
Yes — Belgravia and Knightsbridge are part of the area we cover across West London. This is one of the most valuable residential districts in the world, in the City of Westminster: Thomas Cubitt’s grand white-stucco terraces front the great garden squares — Belgrave Square, Eaton Square, Chester Square, Lowndes Square and Wilton Crescent — with prime lateral apartments, cobbled mews and new-build at the Knightsbridge end. Much of it is part of the Grosvenor Estate. Websters is a firm of RICS chartered surveyors and registered valuers, and our surveyors know this market well.

Local knowledge
What we see in Belgravia property
Belgravia and Knightsbridge’s housing stock
This is prime central London at its most valuable. Thomas Cubitt’s grand white-stucco terraces and crescents front the great garden squares — Belgrave Square, Eaton Square (London’s largest garden square), Chester Square, Lowndes Square and Wilton Crescent — with prime conversion and lateral apartments on Eaton Place and Upper Belgrave Street, cobbled mews houses, and prime new-build towards Knightsbridge. A great deal remains part of the Grosvenor Estate, embassies occupy many of the grandest houses, and values run into the tens of millions.
Estate leasehold, enfranchisement and high-value valuations
Because so much of SW1X is estate-held leasehold, lease extension and collective enfranchisement are central: lease length and terms (with real marriage value on the shorter prime leases), ground rent, service charges, and the Grosvenor Estate’s management scheme, which governs external appearance and alterations. Essentially every home here sits far above the £2m threshold for the High Value Council Tax Surcharge, which the Valuation Office is banding on 2026 values, so owners increasingly want an independent RICS valuation to check or challenge a band. We also value for probate and inheritance tax, matrimonial and capital-gains purposes.
Listed fabric, basements and conservation
Almost every building here is listed — many Grade I or II* on the squares — and all of it lies within the Belgravia and Knightsbridge conservation areas, so on a house or a whole building a Level 3 Building Survey suits, with close attention to the deep basement excavations common here and to any roof works. Alterations carry tight listed-building and conservation consents as well as the estate scheme, and the way the freehold is held shapes the enfranchisement route. The ground is London Clay.

We set out the lease — its length and terms, the marriage value on a shorter prime lease, the ground rent, the service charge and the Grosvenor Estate management scheme — and how the freehold is held, which shapes the enfranchisement route. For a home valued over £2m we flag the High Value Council Tax Surcharge band. On a house we would usually recommend a Level 3 survey, with particular attention to any basement and the listed-building consents alterations carry.
Home surveys start from £900 + VAT, valuations from £700 + VAT and leasehold reform valuations from £850 + VAT; Party Wall work is priced by scope. We give a fixed quote once we know the property and the report you need.
