Working in Weymouth

As well as Weymouth itself (DT3 and DT4), we survey in Dorchester, Poole and Yeovil.

Homes in and around Weymouth vary, so we look at the floor, the walls and the water system before we price anything. We survey cloakrooms in Weymouth with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. If the only toilet in your Weymouth home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips.

Supplies across most of Dorset 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

  • Lighting wired by a qualified electrician, tested and certified
  • An extractor fan ducted to outside, wired with an overrun timer or linked to the light
  • 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

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.

Finishes

A small room can carry a bolder tile or wallpaper. A feature wall behind the WC costs far less here than in a full bathroom because there is so little of it.

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.

More about cloakrooms & downstairs WCs

Cloakrooms & downstairs WCs in Weymouth: questions

How much should I budget for a cloakroom or downstairs WC in Weymouth?

A cloakroom or downstairs WC in Weymouth usually costs £1,850–£4,600 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose. After the free survey you get an itemised written quote, and the price is fixed in writing once the layout and products are agreed.

Is the water hard in Weymouth?

Supplies across most of Dorset 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.

Who handles building control for a cloakroom or downstairs WC in Weymouth?

Building control for Weymouth is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does a cloakroom or downstairs WC take?

Allow 2–4 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Weymouth.

Can I have a macerator toilet in a downstairs cloakroom?

Yes, provided the house already has a WC on gravity drainage, for example in the main bathroom. A macerator pumps the waste through a small-bore pipe, so it can serve a cloakroom some distance from the soil stack. It needs a fused electrical supply, makes a noise while it runs and should only take toilet waste and paper.
