Working in Finchley

We work right across Finchley — N2, N3 and N12 — and in neighbouring Muswell Hill and Cricklewood.

London homes in Finchley often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. If the en-suite in your Finchley home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. If your Finchley 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 Finchley 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
An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
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

Decisions to make first

Door type

An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.

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.

En-suites in Finchley: questions

How much does an en-suite cost in Finchley?

An en-suite in Finchley usually costs £5,600–£11,250 including VAT. Expect the lower end for a like-for-like job with standard products, and the upper end if things move or you choose premium finishes. Your quote is itemised and fixed in writing once agreed.

How long does an en-suite take?

Allow 4–8 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Finchley.

Is the home survey in Finchley really free?

Yes. We visit, measure the room, check the pipework, drainage and electrics, and talk through what you want. You then get a written, itemised quote with no obligation to go ahead.

Do you cover N2 in Finchley?

Yes. We cover all of Finchley, including N2, N3 and N12, and nearby Muswell Hill, Cricklewood and Kilburn. Survey visits are free and arranged at a time that suits you.

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.
