Air Source Heat Pump & Heating Specialists in Essex | Clean Therm

Why Choose Clean Therm for Heat Pumps?

At Clean Therm, we help homeowners switch to air source heat pumps — a cleaner, more efficient way to heat your home. These systems absorb heat from the outside air and use it to warm your radiators, underfloor heating, and hot water. Even on colder days, they work efficiently to reduce your carbon footprint and energy bills.

With over 18 years of heating experience and Gas Safe registration, we’ve launched Clean Therm to bring modern, renewable heating systems to homes across Leigh-on-Sea, Southend, and the wider Essex area.

Whether you live in a new build, have solar panels, or want to upgrade from a traditional boiler, we’ll help you explore if a heat pump is right for your home. We work with MCS-accredited partners so you can still benefit from the £7,500 government Boiler Upgrade Scheme (BUS) — without the stress of dealing with the paperwork yourself.

We only recommend heat pumps for homes that are genuinely suitable — no hard sell, just honest advice and expert help from start to finish.

Is My Home Suitable for an Air Source Heat Pump?

Not every home is ready for a heat pump — but many across Essex already are.

At Clean Therm, we only recommend air source heat pumps where they’ll genuinely save you money and reduce your carbon footprint.

We typically install heat pumps for:

Semi-detached and detached homes with outside space
Properties with good loft or cavity wall insulation
Homes with radiators that are already large enough (or can be upgraded)
Households looking to cut energy bills and futureproof their heating

We always give honest advice — if a heat pump isn’t right for your home, we’ll tell you upfront.

But don’t worry — if your property isn’t suitable, we can still help. Our sister company, Harry Tiffin Plumbing & Heating, has over 18 years of experience with boiler installations, heating repairs, and plumbing work across Essex. Whatever your home needs, we’ll make sure the job gets done right.
