Working in Swindon
We cover every part of Swindon, including SN1, SN2, SN3 and 1 more postcode districts, and nearby Calne (12.7 miles) and Cirencester (13.8 miles).
Swindon is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Swindon cloakroom has no window, we size and duct the extractor fan so the room clears properly. If the only toilet in your Swindon home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips.
Supplies across most of Wiltshire are 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 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
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
Decisions to make first
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.
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.
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.
