Working in Hemel Hempstead
We cover every part of Hemel Hempstead, including HP1, HP2 and HP3, and nearby Berkhamsted (5 miles) and St Albans (5 miles).
Hemel Hempstead has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. If you live in a Hemel Hempstead flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. If the en-suite in your Hemel Hempstead home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Water across much of Hertfordshire is very hard. If your supply in Hemel Hempstead 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 pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- A door that suits a tight space: inward, outward, sliding or a pocket door
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
Decisions to make first
Exposed or concealed valve
An exposed bar valve is quicker to fit and easy to service. A concealed valve looks cleaner but sits inside the wall, so plan how it will be reached for repairs.
Shower size
A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.
Rules that apply in England
In England, a new en-suite brings in Part H for the new connection to the soil stack, Approved Document F for ventilation, at 15 litres per second intermittent or 8 litres per second continuous extract, and Part P for the new circuits. The electrician should be registered with a competent person scheme, or the work notified to building control. On a refit, avoid replacing the fan with a less effective one.
