What does a cloakroom or downstairs WC cost in Portsmouth?

Working in Portsmouth
As well as Portsmouth itself (PO1, PO2, PO3 and 3 more postcode districts), we survey in Gosport, South Hayling and Fareham.
In a city the size of Portsmouth, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If your Portsmouth cloakroom has no window, we size and duct the extractor fan so the room clears properly. We survey cloakrooms in Portsmouth with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
Most of Hampshire has 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
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
- Lighting wired by a qualified electrician, tested and certified
- Strip-out of the old fittings, waste removal and making good on the hall side
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
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.
