Working in Chertsey

As well as Chertsey itself (KT15, KT16 and TW17), we survey in Weybridge, Staines and Egham.

Being a smaller town does not change how we work in Chertsey: free survey, written quote, one team. We quote new en-suites in Chertsey only after checking the drainage route on site, so the price reflects the work your house actually needs. If your Chertsey home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue.

Most of Surrey has hard water. If your supply in Chertsey 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
Tiling, silicone, testing and making good on the bedroom side of any new walls
Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified

Decisions to make first

Shower size

A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.

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.

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 Chertsey: questions

What is the price of an en-suite in Chertsey?

An en-suite in Chertsey usually costs £5,000–£10,000 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose.

Is the water hard in Chertsey?

Who handles building control for an en-suite in Chertsey?

Building control for Chertsey is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

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.
