Working in Formby
We cover every part of Formby, including L37 and L38, and nearby Maghull (6 miles) and Southport (6.5 miles).
Being a smaller town does not change how we work in Formby: free survey, written quote, one team. We quote new en-suites in Formby only after checking the drainage route on site, so the price reflects the work your house actually needs. For an en-suite in Formby, the first question at the survey is always where the waste can reach the soil stack.
Supplies across most of Merseyside are soft. If that holds for your street in Formby, 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
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
Decisions to make first
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.
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.
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.
