We supply and fit vented and unvented hot water cylinders across Wandsworth — from airing cupboard replacements in Battersea and Putney’s period houses, to pressurised unvented cylinders in Wandsworth Town and Nine Elms new-builds, and loft-tank-fed systems in Earlsfield and Tooting’s terraces. Old cylinder removed, fixed price, 12-month guarantee.

Hot water cylinders typically last 10–15 years. Here’s what tends to prompt a replacement across the borough’s mix of period houses and flats.
Rust staining, damp around the airing cupboard, or a visible leak from the cylinder itself is usually a sign the tank has corroded internally and needs replacing rather than repairing — common in older cylinders across Battersea and Putney's period houses.
An undersized cylinder installed for a smaller household often runs out of hot water once a Wandsworth Town or Nine Elms flat gains an extra bathroom or occupant — a larger or unvented replacement usually resolves this.
Older vented cylinders fed from a loft tank often can't match the pressure of modern showers. Switching to an unvented cylinder gives mains pressure hot water throughout the property.
Removing an old loft tank and vented cylinder in favour of a compact unvented system is a common upgrade during renovations of Earlsfield and Tooting terraces, freeing up valuable storage space.
A straightforward supply-and-fit service, carried out at a fixed price before any work begins.
We assess your existing cylinder, hot water demand and pipework to recommend the right vented or unvented replacement for your property.
You receive a fixed price covering the new cylinder, removal of the old one and all fitting work before anything starts.
The old cylinder is drained and removed, and the new cylinder is fitted, connected and commissioned by a fully trained engineer.
We test hot water flow and pressure at every outlet before we leave, with the work covered by our 12-month guarantee.
Cost depends on cylinder type and size, and how accessible the airing cupboard or loft is. All prices are confirmed before we attend — no call-out charge.

Our old vented cylinder in Battersea started leaking into the airing cupboard. Had it replaced like-for-like the same week, old tank removed and no mess left behind.
New-build flat near Wandsworth Town never had great shower pressure. Switched to an unvented cylinder and removed the old loft tank at the same time — proper mains pressure now.
Growing family in Earlsfield kept running out of hot water in the mornings. Fitted a larger unvented cylinder and it’s completely solved it, everyone gets a hot shower now.
Yes. We cover the entire Wandsworth borough including Battersea, Clapham Junction, Putney, Wandsworth Town, Balham, Earlsfield, Tooting and Roehampton — postcodes SW11, SW12, SW15, SW17 and SW18. Our engineers are based locally across South West London.
A like-for-like vented cylinder replacement starts from £780. An unvented cylinder replacement starts from £1,450, and a full vented-to-unvented upgrade including loft tank removal starts from £1,850. All prices are confirmed before work begins.
Unvented cylinders give mains pressure hot water at every outlet and don't need a loft tank, making them popular for flats and properties wanting better shower pressure. Vented cylinders are typically cheaper to replace like-for-like where a loft tank is already in place. We'll advise on the best option during survey.
A like-for-like vented replacement usually takes 3–4 hours. An unvented replacement typically takes 4–6 hours, and a full vented-to-unvented upgrade including loft tank removal can take a full day.
