Working in Feltham
We work right across Feltham — TW4, TW13 and TW14 — and in neighbouring Ashford and Hounslow.
In Feltham, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Feltham home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. If your Feltham en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Supplies across most of Greater London are very hard. If your supply in Feltham 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 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- A door that suits a tight space: inward, outward, sliding or a pocket door
Decisions to make first
Noise
Acoustic insulation in the stud walls and a quiet fan make a real difference when one of you showers early while the other is still asleep.
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.
