What does an en-suite cost in Chesham?
In Chesham, an en-suite typically costs £5,000–£10,000 including VAT, based on South East England prices. We adjust the national guide for South East England, where prices are typically about 12% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Chesham
We work right across Chesham — HP5 — and in neighbouring Amersham on the Hill and Amersham.
Chesham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We quote new en-suites in Chesham only after checking the drainage route on site, so the price reflects the work your house actually needs. If the en-suite in your Chesham home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Water across much of Buckinghamshire is hard. If your supply in Chesham 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
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
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.
Shower size
A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.
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.
