General info


Best Gapp is a Belgravia estate agent, chartered surveyor and property valuer that has been offering an unrivalled service to clients since 1900. Choosing the right estate agent is a critical decision – it can make the difference between getting a really good price, and not selling your house at all. Best Gapp has more than 100 years’ experience of Belgravia. The company was based at 1 Sloane Square until 1969 before the business – then known as Best Gapp and Cassells – moved to its current base at 81 Elizabeth Street in the heart of Belgravia.
