Working in Hertford
As well as Hertford itself (SG13 and SG14), we survey in Ware, Hoddesdon and Welwyn Garden City.
Homes in and around Hertford vary, so we look at the floor, the walls and the water system before we price anything. If your Hertford loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have. For a loft bathroom in a tank-fed Hertford home, we work out how the shower will get its pressure before choosing a single fitting.
Most of Hertfordshire has very hard water. If your supply in Hertford 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 shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- A check of the floor joists where a bath or large shower tray will sit
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
Decisions to make first
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
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.
