Working in Chelmsford
We cover every part of Chelmsford, including CM1, and nearby Billericay (7.7 miles) and Witham (8.5 miles).
Chelmsford is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. For a loft bathroom in a tank-fed Chelmsford home, we work out how the shower will get its pressure before choosing a single fitting. If your Chelmsford home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Water across much of Essex is very hard. If your supply in Chelmsford 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 check of the floor joists where a bath or large shower tray will sit
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A survey of the headroom across the room, with the usable height marked at each fitting position
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.
