Working in Welling
We work right across Welling — DA6, DA15 and DA16 — and in neighbouring Bexley and Eltham.
In Welling, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. We survey cloakrooms in Welling with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. For a new cloakroom in Welling, 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
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A concealed cistern frame or WC unit where the space allows
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Lighting wired by a qualified electrician, tested and certified
Decisions to make first
Macerator or gravity
Gravity drainage is silent and needs no maintenance. A macerator lets a WC go where a pipe could not otherwise fall, provided another WC in the house is on gravity drainage.
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.
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.
