For homeowners looking to move away from gas, we design and install air-source heat pump systems sized to the property's actual heat loss. That includes the heat pump, hot-water cylinder, upgraded radiators or underfloor runs where needed, and the full electrical and controls commissioning.
Because we understand the older Kent and London housing stock — insulation levels, single-skin walls, existing radiator sizes — we size the system honestly. We won't oversell a heat pump where the fabric isn't ready; we'll tell you what upgrades are needed first so the system genuinely performs and keeps running costs down.
What's included
- Air source heat pump design and installation
- Whole-house heat loss calculations
- Hot water cylinder supply and connection
- Radiator and underfloor heating upgrades

Heat Pump Installations FAQs
Is my home suitable for a heat pump?
It depends on your property's heat loss, insulation and existing emitter sizes. We carry out a proper heat-loss survey first and give you an honest answer — including any radiator or insulation upgrades needed — so the system performs rather than disappoints.
Can a heat pump work with my existing radiators?
Sometimes, if they're generously sized. Heat pumps run at lower flow temperatures than gas boilers, so we size each emitter against the heat loss and tell you which radiators need upgrading to larger or low-temperature models.
Will a heat pump lower my running costs?
A correctly sized heat pump is typically cheaper to run than a gas boiler, especially with good insulation. We model the expected running costs against your current setup as part of the survey so you can decide with real numbers, not marketing claims.
