Working in Greenwich
In Greenwich we cover SE3, SE7, SE10 and 1 more postcode districts; we also cover Blackheath, 1.2 miles away, and Canary Wharf.
In Greenwich, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. For a new cloakroom in Greenwich, the first thing we look at is where the nearest drain or soil stack runs. If the only toilet in your Greenwich home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips.
Water across much of Greater London is very hard. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Lighting wired by a qualified electrician, tested and certified
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
Decisions to make first
Finishes
A small room can carry a bolder tile or wallpaper. A feature wall behind the WC costs far less here than in a full bathroom because there is so little of it.
Basin
A corner basin fits the tightest rooms. A slim vanity basin with a cupboard underneath gives somewhere to keep spare toilet rolls and soap, and hides the trap.
Rules that apply in England
In England, a new WC connected to the soil stack or drain is drainage work under Part H, and a newly formed cloakroom without an opening window should have mechanical extract; Approved Document F gives 6 litres per second as the design rate for a WC, against 15 for a bathroom. Because a cloakroom has no bath or shower, adding a light to an existing circuit is not notifiable under Part P, but a new circuit is.
