Working in Winchester
In Winchester we cover SO21, SO22 and SO23; we also cover Eastleigh, 6.9 miles away, and Romsey.
Winchester is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Winchester home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. If the en-suite in your Winchester home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Supplies across most of Hampshire are hard. If your supply in Winchester 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
Decisions to make first
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.
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
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.
