What does an en-suite cost in Amersham?
Guide price in Amersham: £5,000–£10,000 including VAT, depending on the room and what you choose. We adjust the national guide for South East England, where prices are typically about 12% above the UK average.

Working in Amersham
In Amersham we cover HP6 and HP7; we also cover Amersham on the Hill, 0.7 miles away, and Chesham.
Amersham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If you live in a Amersham flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. We quote new en-suites in Amersham only after checking the drainage route on site, so the price reflects the work your house actually needs.
Supplies across most of Buckinghamshire are hard. If your supply in Amersham 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
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A door that suits a tight space: inward, outward, sliding or a pocket door
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
Decisions to make first
Exposed or concealed valve
An exposed bar valve is quicker to fit and easy to service. A concealed valve looks cleaner but sits inside the wall, so plan how it will be reached for repairs.
Noise
Acoustic insulation in the stud walls and a quiet fan make a real difference when one of you showers early while the other is still asleep.
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.
