Working in Chiswick
In Chiswick we cover W3, W4 and W6; we also cover Acton, 1.4 miles away, and Shepherds Bush.
London homes in Chiswick often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Where your Chiswick home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. We survey cloakrooms in Chiswick with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
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
- Lighting wired by a qualified electrician, tested and certified
- 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
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
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.
Basin
A corner basin fits the tightest rooms. A slim vanity basin with a cupboard underneath gives somewhere to keep spare toilet rolls and soap, and hides the trap.
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.
