Working in Derry

As well as Derry itself (BT47 and BT48), we survey in Limavady, Coleraine and Magherafelt.

Derry 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 Derry bathroom layout is changing, the soil stack position is checked first, because it decides where the WC can go. In Derry flats, any change to the WC or wastes is planned with the lease and the flat below in mind.

Supplies across most of County Londonderry are soft. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

Shower pumps on gravity systems, and macerators or pumped wastes where gravity drainage cannot reach
A check of your hot water system, and the pressure and flow rate at the bathroom
Draining down and isolating supplies, with the rest of the house back on water as soon as possible
The WC connected to the soil stack, or a new branch where the WC is moving

Decisions to make first

Gravity or pumped waste

Gravity drainage is always the first choice. A shower waste pump or macerator solves a run that cannot fall, but adds noise, a power supply and servicing.

Concealed or exposed valves

Concealed shower valves look neater but need an access route for servicing. Exposed bar valves are easier to reach and replace.

Rules that apply in Northern Ireland

In Northern Ireland, the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009 apply to new fittings. New drainage and connections are a matter for building control.

More about bathroom plumbing

Bathroom plumbing in Derry: questions

How much should I budget for bathroom plumbing work in Derry?

Bathroom plumbing work in Derry usually costs £550–£3,500 including VAT. The final figure comes down to what you choose and what we find at the survey; your written quote lists every item so you can see where the money goes.

Do you cover BT47 and BT48 in Derry?

Yes. We cover all of Derry, including BT47 and BT48, and nearby Limavady, Coleraine and Magherafelt. Survey visits are free and arranged at a time that suits you.

Is the water hard in Derry?

Does bathroom plumbing work in Derry need building control approval?

Building control in Derry is run by the local district council. Where approval is needed, for example for new drainage, we tell you at the survey and handle it as part of the job.

Can a toilet be moved anywhere in a bathroom?

Not anywhere. A WC needs a 110 mm waste with enough fall to reach the soil stack, and the joists limit which way that pipe can run under the floor. Where gravity drainage cannot work, a macerator is an option only if the home also has a WC on gravity drainage.
