Quartz worktops in Kensington and Chelsea

33rd of 33 London boroughs, highest first

The original kitchen here was a scullery against an outside wall with the waste already through it. Where the waste runs still decides the sink, and the sink is the largest cut-out. Templated in your kitchen, fabricated to that survey, fitted by our own team.

An island is a yield question first. We can usually tell you at survey whether it comes out of one slab or two, and that is the number that moves. The cut list carries it; the specification does not change.

The middle half of our quartz range runs from £150 to £270 per square metre, across 69 colours. On rooms this size the number is set by slab yield: how many pieces come out of a slab, and whether an island needs a second one. Square metreage is the last thing we work out, not the first.

Across Kensington and Chelsea's 19 neighbourhoods, the share of homes that are flats runs from 8% in World's End to 98% in Earl's Court, with Golborne (96%) and West Brompton (95%) next. Where the kitchen is up a flight, each quartz piece is sized to the stairwell before it is sized to the room.

North Kensington has the highest share of converted houses of the 19 Kensington and Chelsea neighbourhoods we list, at 38%, ahead of West Brompton (36%) and South Kensington (32%); World's End has the lowest, at 0%. A conversion usually means a stair that turns and a kitchen made out of another room, so the quartz is cut from a template taken once the units are in.

Free samples are posted for the Worktop Worx quartz collection; other quartz is judged from the slab.
