Working in Royston
In Royston we cover SG8; we also cover Letchworth Garden City, 9.8 miles away, and Biggleswade.
Being a smaller town does not change how we work in Royston: free survey, written quote, one team. If the en-suite in your Royston home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. For an en-suite in Royston, the first question at the survey is always where the waste can reach the soil stack.
Supplies across most of Cambridgeshire are very hard. If your supply in Royston 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 short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- Tiling, silicone, testing and making good on the bedroom side of any new walls
Decisions to make first
Refit or new en-suite
A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.
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.
