Working in St Helens

As well as St Helens itself (WA9, WA10, WA11 and 1 more postcode districts), we survey in Prescot, Ashton in Makerfield and Huyton.

St Helens has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. If the en-suite in your St Helens home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. For an en-suite in St Helens, the first question at the survey is always where the waste can reach the soil stack.

Water across much of Merseyside is soft. If that holds for your street in St Helens, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A door that suits a tight space: inward, outward, sliding or a pocket door
IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear

Decisions to make first

Door type

An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.

Refit or new en-suite

A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.

Rules that apply in England

In England, a new en-suite brings in Part H for the new connection to the soil stack, Approved Document F for ventilation, at 15 litres per second intermittent or 8 litres per second continuous extract, and Part P for the new circuits. The electrician should be registered with a competent person scheme, or the work notified to building control. On a refit, avoid replacing the fan with a less effective one.

En-suites in St Helens: questions

How much does an en-suite cost in St Helens?

An en-suite in St Helens usually costs £4,200–£8,500 including VAT. Expect the lower end for a like-for-like job with standard products, and the upper end if things move or you choose premium finishes. Your quote is itemised and fixed in writing once agreed.

Is the water hard in St Helens?

Who handles building control for an en-suite in St Helens?

Building control for St Helens 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 an en-suite take?

Allow 4–8 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 St Helens.

Do I need building regulations approval for an en-suite?

A new en-suite usually does, because it involves new drainage, an extractor fan and new electrical circuits. A like-for-like refit of an existing en-suite normally does not, apart from any electrical work that is notifiable where you live. We tell you which parts apply at the survey.
