Working in Surbiton
We work right across Surbiton — KT1, KT5 and KT6 — and in neighbouring East Molesey and Esher.
London homes in Surbiton often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For a new cloakroom in Surbiton, the first thing we look at is where the nearest drain or soil stack runs. Where your Surbiton home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go.
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 concealed cistern frame or WC unit where the space allows
- Lighting wired by a qualified electrician, tested and certified
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Strip-out of the old fittings, waste removal and making good on the hall side
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.
