Working in Wellingborough
In Wellingborough we cover NN8; we also cover Rushden, 4 miles away, and Kettering.
Homes in and around Wellingborough vary, so we look at the floor, the walls and the water system before we price anything. If your Wellingborough house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Wellingborough 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 Northamptonshire are hard. If your supply in Wellingborough 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 shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
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.
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
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.
