Working in Banbury
As well as Banbury itself (OX16), we survey in Bicester, Daventry and Royal Leamington Spa.
Homes in and around Banbury vary, so we look at the floor, the walls and the water system before we price anything. We quote new en-suites in Banbury only after checking the drainage route on site, so the price reflects the work your house actually needs. If you live in a Banbury flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Supplies across most of Oxfordshire are hard. If your supply in Banbury 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 shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- A door that suits a tight space: inward, outward, sliding or a pocket door
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
Decisions to make first
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
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.
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.
