Heat Pumps in Lowestoft
Much of Lowestoft and the surrounding Suffolk countryside is off the gas grid, meaning many homes rely on oil, LPG, or electric heating — all significantly more expensive than a heat pump. A heat pump replaces your boiler entirely, using electricity to extract heat from outdoor air and deliver it to your radiators and hot water cylinder at around 3–4× the efficiency of direct electric heating.

The BUS grant is paid directly to Green Hat, who deducts it from your installation cost. You pay the net figure — you never touch the grant money or deal with the application. To qualify, your property must have a valid EPC with no outstanding loft or cavity wall insulation recommendations. We check eligibility during the free survey and manage the full application.
How Heat Pump Installation Works
Free home survey and heat loss calculation
We visit your Lowestoft property to measure room-by-room heat loss, assess insulation, check radiator sizes, and identify the right heat pump model and output. No charge, no obligation.
Detailed quote and BUS grant application
We provide a fixed-price quote showing the full cost, grant deduction, and net cost to you. We then apply for the BUS grant on your behalf before scheduling the installation.
Installation — typically 2–3 days
Our MCS-certified engineers fit the external unit, internal cylinder (if needed), controls, and connect to your existing pipework and radiators. Disruption is minimal — most Lowestoft homeowners remain in the property throughout.
Commissioning and handover
We commission and test the system, set weather compensation curves for your property's heat loss profile, and walk you through the controls. Your MCS certificate is registered, activating all manufacturer warranties and grant compliance.

Solar-Powered Heating in Lowestoft
Lowestoft is Britain's most easterly town, receiving the first sunrise each day. Annual irradiance exceeds 1,055 kWh/m² — the highest in Suffolk. Maritime breezes keep panels at optimal operating temperature, boosting generation by 3–5% compared to inland sites. When combined with solar panels, a heat pump in Lowestoft can run on free electricity for much of the year — reducing heating costs by an additional 30-50% beyond the heat pump efficiency gains alone.
Complete Home Energy System in Lowestoft
A heat pump works best as part of a complete renewable energy system. Solar panels generate free electricity to power the heat pump, a battery stores surplus for overnight heating demand, and an EV charger completes the package. For Lowestoft households, the combined system typically reduces total energy costs by 60-80% and eliminates fossil fuel dependency entirely.
