Working in Sudbury
We work right across Sudbury — CO10 — and in neighbouring Colchester and Haverhill.
Being a smaller town does not change how we work in Sudbury: free survey, written quote, one team. If you live in a Sudbury flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. For an en-suite in Sudbury, the first question at the survey is always where the waste can reach the soil stack.
Supplies across most of Suffolk are very hard. If your supply in Sudbury 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
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
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.
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.
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.
