Working in Blackheath
We cover every part of Blackheath, including SE3, SE10 and SE13, and nearby Greenwich (1.2 miles) and Catford (1.8 miles).
In Blackheath, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If you are refreshing a dated cloakroom in Blackheath, a wall-hung WC and slim vanity can change the room in a few days. If your Blackheath cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Most of Greater London has very hard water. 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 new waste connection to the soil stack or drain, or a macerator where the rules allow it
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
- Splashback or feature tiling and a new floor, often LVT or porcelain
- Lighting wired by a qualified electrician, tested and certified
Decisions to make first
WC style
A wall-hung WC on a frame gives the most floor space and looks neat. A back-to-wall pan in a short furniture unit is easier to fit against an uneven wall.
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.
