Which neighbouring authorities border Kensington and Chelsea?
- Westminster — adjoining Kensington and Chelsea, with 56 conservation areas centred on SW1. A 1930s semi project on the far side of the Kensington and Chelsea line is determined by Westminster City Council, so the Kensington and Chelsea quote for 1930s semi projects is checked against Westminster guidance before it is issued.
- Hammersmith and Fulham — the Hammersmith and Fulham boundary runs against Kensington and Chelsea, so a 1930s semi project a street from Kensington and Chelsea is decided by Hammersmith & Fulham Council instead. Hammersmith and Fulham runs 45 conservation areas across W6 and its neighbours, which is why 1930s semi projects priced for Kensington and Chelsea are re-checked against Hammersmith and Fulham policy whenever the Kensington and Chelsea address sits on that edge.
- Brent — cross the Kensington and Chelsea boundary and Brent Council takes the 1930s semi project instead, applying 22 conservation areas of its own around NW2. We re-price 1930s semi projects at the Kensington and Chelsea edge because Brent policy and Kensington and Chelsea policy rarely align on 1930s semi project depth.
