Working in Witney
As well as Witney itself (OX28), we survey in Carterton, Oxford and Abingdon.
In Witney, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Witney loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have. We plan loft bathrooms in Witney around the roof line, so the shower sits where you can stand and the eaves become storage.
Most of Oxfordshire has hard water. 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 survey of the headroom across the room, with the usable height marked at each fitting position
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A check of your hot-water system and of the pressure and flow you actually get at loft level
Decisions to make first
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
Gravity or pumped waste
Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
