Working in Northolt
We cover every part of Northolt, including HA2, UB5 and UB6, and nearby Greenford (1.5 miles) and Harrow (2.6 miles).
London homes in Northolt often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If you are refreshing a dated cloakroom in Northolt, a wall-hung WC and slim vanity can change the room in a few days. For a new cloakroom in Northolt, the first thing we look at is where the nearest drain or soil stack runs.
Supplies across most of Greater London are 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
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
- Lighting wired by a qualified electrician, tested and certified
- 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.
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
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.
