What does an en-suite cost in Lancing?

Working in Lancing
In Lancing we cover BN15; we also cover Shoreham-by-Sea, 2.1 miles away, and Worthing.
Lancing gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If the en-suite in your Lancing home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. If your Lancing home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue.
Supplies across most of West Sussex are hard. If your supply in Lancing 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
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
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.
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.
