Working in Gosport
In Gosport we cover PO12 and PO13; we also cover Portsmouth, 1.7 miles away, and Southsea.
Gosport has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. We quote new en-suites in Gosport only after checking the drainage route on site, so the price reflects the work your house actually needs. If the en-suite in your Gosport home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Most of Hampshire has hard water. If your supply in Gosport 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
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
Decisions to make first
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.
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.
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.
