Working in Gerrards Cross
In Gerrards Cross we cover SL9 and UB9; we also cover Chalfont St Peter, 1.6 miles away, and Uxbridge.
Being a smaller town does not change how we work in Gerrards Cross: free survey, written quote, one team. If your Gerrards Cross house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Gerrards Cross loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Supplies across most of Buckinghamshire are hard. If your supply in Gerrards Cross 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
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A survey of the headroom across the room, with the usable height marked at each fitting position
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
Decisions to make first
Bath or no bath
A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
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.
