Working in Cobham

We work right across Cobham — KT11 — and in neighbouring Esher and Weybridge.

Being a smaller town does not change how we work in Cobham: free survey, written quote, one team. If your Cobham house has a combi boiler, a loft shower can usually run on mains pressure without a pump. If your Cobham loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have.

Water across much of Surrey is hard. If your supply in Cobham 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 check of your hot-water system and of the pressure and flow you actually get at loft level
A survey of the headroom across the room, with the usable height marked at each fitting position
Fitted furniture made to the eaves, so the low space behind the slope becomes storage
An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces

Decisions to make first

Bath or no bath

A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.

Gravity or pumped waste

Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.

Rules that apply in England

In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.

More about loft bathrooms

Loft bathrooms in Cobham: questions

How much should I budget for a loft bathroom in Cobham?

A loft bathroom in Cobham usually costs £7,300–£14,500 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.

Who handles building control for a loft bathroom in Cobham?

Building control for Cobham 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.

How long does a loft bathroom take?

Allow 6–12 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 Cobham.

Is the home survey in Cobham 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 I need a pump for a loft shower?

You need a pump if your hot water comes from a cylinder fed by a cold tank, because the tank usually sits at or below the height of a loft shower and gives almost no pressure. A combi boiler or unvented cylinder supplies mains pressure, so no pump is needed, though the flow can drop when other taps run. Shower pumps must only be used on gravity systems, never connected to the mains.
