What does an en-suite cost in Ashford?
In Ashford, an en-suite typically costs £5,000–£10,000 including VAT, based on South East England prices. Prices in South East England run at about 12% above the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Ashford
We cover every part of Ashford, including TW15, TW16 and TW18, and nearby Staines (2.1 miles) and Feltham (2.1 miles).
In Ashford, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If you live in a Ashford flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. If the en-suite in your Ashford home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Most of Surrey has hard water. If your supply in Ashford 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 pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- 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.
