Working in Finchley
We work right across Finchley — N2, N3 and N12 — and in neighbouring Muswell Hill and Cricklewood.
London homes in Finchley often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For a new cloakroom in Finchley, the first thing we look at is where the nearest drain or soil stack runs. If the only toilet in your Finchley home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips.
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
- Strip-out of the old fittings, waste removal and making good on the hall side
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- Lighting wired by a qualified electrician, tested and certified
Decisions to make first
Door
An outward-opening door is usually needed so it does not hit the WC. A sliding door suits a narrow hallway where an outward door would block the way.
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.
