Which Shower Power Booster Is Right for Your Home?
Select your heating or hot water system below and we'll show you the compatible Shower Power Booster pumps.

Gravity Fed Systems
One of our most common applications for customers who need to boost poor water pressure for their gravity-fed system.

Combi Boilers
The only pump that works on the hot side of a combi boiler. If your shower fades when a tap runs, or the boiler cuts out mid-shower, this is your fix.

Unvented Systems
If you have a Megaflow or a similar unvented cylinder, SPB is the only WRAS Approved pump designed to boost on the hot side of an unvented system.

Electric Showers
Increase the water pressure to compatible electric showers for a stronger more satisfying hot shower. Stop it shutting down due to low pressure.

Mains Pressure
Pump solutions for properties experiencing low incoming mains water pressure or reduced water flow.

Radiator Booster
Pumps to balance radiator systems and eliminate lazy radiators. All radiators can run hot and it works on any system.
The Smarter Alternative to Traditional Pumps
Designed and made in Britain, the compact Shower Power Booster provides a simple, energy-efficient way to improve water flow and pressure while using less energy and producing less noise than many traditional pumps.
DIY in 3 Easy Steps
A competent DIYer can fit a Shower Power Booster safely in minutes.
No Electrician Needed
SPB pumps run on 12V, with a transformer that plugs into any normal socket. Safe for bathroom installations with no need for rewiring.
Retrofit, Don't Replace
A new combi boiler costs £1,800 to £4,000, and no boiler can fix low incoming mains pressure. A Shower Power Booster is from £143.
Your warranty covers DIY installation
Fit it yourself or use a plumber, or use a handyman, and you're still covered. Two years as standard, three if you upgrade.
Quiet, and pennies to run
The brushless motor provides dependable performance with less noise.It's also cheaper to run with 12 watts, around 5% of what a Power Shower draws.
Trusted and safe
WRAS approved, made in the UK and tested on every pump, with a 30 day money back guarantee and 4.8 stars on Trustpilot.
