Why Water Heater Installation Matters in Southwark

Southwark's 19th-century sewer system is one of the oldest in London, built by Bazalgette in the 1860s. Victorian properties in Bermondsey frequently experience drain backing-up caused by the age and capacity limits of the original sewer infrastructure.

Housing stock: Victorian terraces in Bermondsey and Peckham, 1960s–70s council blocks near Elephant & Castle, and significant new-build towers on the South Bank.

Common Questions — Water Heater Installation in Southwark

What is the difference between vented and unvented water heaters in Southwark?

Vented systems in Southwark are gravity-fed from a cold water tank in the loft and deliver lower water pressure. Unvented systems connect directly to the mains and deliver full mains pressure to all outlets. Unvented systems require more space and G3-qualified engineers — but the performance improvement is significant.

Can you install a Megaflo in my Southwark property?

Yes. Our G3-qualified engineers install and commission Megaflo unvented cylinders (and equivalent brands) across Southwark. We assess your incoming mains pressure and flow rate first — if the mains can't support the cylinder, we'll advise alternatives.

How much does a new hot water cylinder cost in Southwark?

A vented cylinder replacement in Southwark starts from £800 installed. A new unvented Megaflo installation typically costs £1,500–£2,500 depending on cylinder capacity and any pipework changes required. We provide a fixed quote before starting.
