From leaks to poor pressure, these are the reasons our engineers are called out to replace hot water cylinders most often across Bromley.
Older copper cylinders, common in Chislehurst and Bromley’s period properties, corrode with age and eventually develop leaks around welds or fittings.
A vented cylinder relies on gravity from a loft tank, giving noticeably weaker pressure than mains-fed water — a common frustration in larger Beckenham and Orpington homes.
An undersized cylinder struggles to keep up with a growing family’s demand, particularly across multiple bathrooms in larger Bromley properties.
A faulty immersion element or cylinder thermostat can leave a household without hot water even when the rest of the heating system is working fine.
A correctly sized, properly commissioned cylinder, not just a like-for-like swap of the old for the new.
Your engineer reviews your current cylinder, household hot water demand, and whether an unvented upgrade is suitable for your Bromley property.
The existing cylinder is safely drained and removed, along with any associated pipework that needs replacing.
The new cylinder is installed and connected, with safety valves, expansion vessels and controls fitted correctly for vented or unvented systems.
The system is tested for correct pressure and temperature, and unvented installations are certified to Building Regulations G3 as required by law.
A correctly specified cylinder improves daily comfort and removes the risk of a sudden leak.
Upgrading to an unvented cylinder delivers strong, consistent pressure to every shower and tap, without relying on gravity from a loft tank.
Replacing an ageing, corroding cylinder proactively avoids the water damage and disruption a sudden leak can cause to ceilings and flooring below.
A correctly sized cylinder keeps up with multiple bathrooms and showers running back-to-back, common in larger Bromley family homes.
Removing a vented system’s cold water tank frees up valuable loft storage space, a popular benefit when upgrading to unvented.
Cost depends on cylinder type, size and whether pipework needs adapting. All prices confirmed before we attend — no call-out charge.

150–180 litre, 1–2 bathroom property

Fast site visits and reliable scheduling across all Bromley postcodes, from Bromley town centre to Chislehurst and Orpington.
Every replacement is based on your actual hot water demand — number of bathrooms, household size and usage — rather than a default size.
All unvented cylinder work is carried out and certified to Building Regulations G3, as legally required for this type of system.
The same fixed pricing applies whether you're in BR7 Chislehurst or BR1 Bromley town centre — no zone uplift, no call-out charge, no extras added after the fact.
A popular upgrade across Bromley's larger properties, requiring careful pipework and loft tank removal — work we carry out regularly.
All cylinder replacement work in Bromley carries our 12-month guarantee, issued in writing on completion.

“Old copper cylinder in our Chislehurst house had started weeping around the base, clearly on its way out. Replaced like-for-like the same week, no fuss and no more worrying about it failing overnight.”
“Fed up with weak shower pressure in our Orpington house for years. Upgraded to an unvented system, removed the loft tank too, and the difference in every shower is honestly night and day.”
“Family of five constantly running out of hot water with the old cylinder. Sized up properly for our household this time, no more cold showers for whoever goes last.”
Yes. We cover the entire Bromley borough — BR1, BR2, BR3, BR4, BR5, BR6 and BR7 — including Bromley town centre, Chislehurst, Orpington, Petts Wood, Beckenham and West Wickham, with no zone surcharge.
A like-for-like vented cylinder replacement starts from £950. An unvented cylinder starts from £1,850 for standard size and £2,400 for larger properties. A full vented-to-unvented upgrade starts from £2,600. All prices confirmed before work begins.
A vented cylinder is fed by gravity from a cold water tank in the loft, giving weaker pressure. An unvented cylinder connects directly to the mains, delivering strong, consistent pressure to every outlet without needing a loft tank.
Yes. Unvented cylinder installations must comply with Building Regulations G3 and be installed by a qualified, certified engineer — which we are for every unvented job we carry out.
This depends on your household size and number of bathrooms. As a guide, a 1–2 bathroom property typically needs 150–180 litres, while larger properties with multiple bathrooms often need 210–300 litres. We confirm the right size during the visit.
Most cylinders last 10–15 years, though this varies with water hardness and maintenance. Signs it's time for a replacement include leaking, corrosion, or noticeably reduced hot water performance.
Fixed price confirmed before we start. Correctly sized, fully certified. 12-month guarantee. All Bromley postcodes.
