Which towns do we cover in Greater London?

Most of Greater London has very hard water. If your supply in Brent 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. We quote new en-suites in Brent only after checking the drainage route on site, so the price reflects the work your house actually needs.

What the job includes

  • 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
  • A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
  • A door that suits a tight space: inward, outward, sliding or a pocket door
  • A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
  • A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage

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.

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.

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.

Rules that apply in England

Forming an en-suite inside an existing bedroom does not normally need planning permission, but it is usually building-regulations work because it adds drainage, ventilation and electrics. All wiring must meet BS 7671, with 30 mA RCD protection on every circuit in the room. A macerator or pumped WC is acceptable only where the home also has a WC on gravity drainage. In a listed building, a new soil or vent pipe through a wall needs listed building consent.

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.

Is the water hard in Greater London?

Most of Greater London has very hard water. If your supply in Brent 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.

Can you put an en-suite anywhere?

Almost anywhere the waste can reach the soil stack. Gravity drainage needs a steady fall in the pipe, so the further the en-suite is from the stack, the more depth you need under the floor or behind boxing. Where that is not possible, a pumped waste or macerator can be used if the home already has a WC on gravity drainage. Our guide to adding an en-suite covers this in more detail.
