What does an en-suite cost in Witney?
Our guide price for an en-suite in Witney is £5,000–£10,000 including VAT. Labour costs in South East England put local prices at about 12% above the UK guide figure. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Witney
As well as Witney itself (OX28), we survey in Carterton, Oxford and Abingdon.
Homes in and around Witney vary, so we look at the floor, the walls and the water system before we price anything. If you live in a Witney 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 Witney 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 Oxfordshire is hard. If your supply in Witney 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
- 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
- Tiling, silicone, testing and making good on the bedroom side of any new walls
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.
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.
