Working in Chorley
We work right across Chorley — PR6 and PR7 — and in neighbouring Horwich and Leyland.
In Chorley, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Chorley home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. For a loft bathroom in a tank-fed Chorley home, we work out how the shower will get its pressure before choosing a single fitting.
Most of Lancashire is supplied with soft water. If that holds for your street in Chorley, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. 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
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- A check of the floor joists where a bath or large shower tray will sit
Decisions to make first
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
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.
