Working in Amersham on the Hill
We work right across Amersham on the Hill — HP5, HP6 and HP7 — and in neighbouring Amersham and Chesham.
Amersham on the Hill gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Amersham on the Hill en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit. If you live in a Amersham on the Hill flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Most of Buckinghamshire has hard water. If your supply in Amersham on the Hill is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- A door that suits a tight space: inward, outward, sliding or a pocket door
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
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.
