Working in Havant
As well as Havant itself (PO9), we survey in Emsworth, Waterlooville and South Hayling.
Homes in and around Havant vary, so we look at the floor, the walls and the water system before we price anything. If your Havant home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. If your Havant loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.
Water across much of Hampshire is hard. If your supply in Havant 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
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- 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
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
Decisions to make first
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.
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.
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.
