What Drives Your Air Source Heat Pump Cost?

Not all heat pumps are created equal. Several factors shape the final air source heat pump cost on your quotation:

• Property Size & Insulation: Bigger homes or poorly insulated buildings need higher-capacity pumps.
• System Design: Standardised kits cost less upfront, but bespoke layouts (like Megawave’s tailored designs) often deliver better performance and long-term savings.
• Refrigerant Type: Many suppliers use standard refrigerants. Megawave exclusively installs R290, a zero-carbon alternative that lowers environmental impact without bumping your installation quote.
• Installation Complexity: Groundworks, pipe runs, and electrical upgrades add to labour. Some installers hide extra fees. At Megawave, you get a clear breakdown from day one.
• Additional Components: Hot water cylinders, radiators, smart controls—all influence the bottom line.

Octopus Energy’s impressive £3,818 figure (after grant) is hard to beat on paper. But it relies on large-scale installations and off-the-shelf components. You might save a few hundred pounds—but miss out on custom efficiency gains and that eco-friendly R290 edge.

Running Costs and Savings

Air source heat pumps boast a high Coefficient of Performance (COP), often around 3.5. That means:
– For every 1 kW of electricity, you get 3.5 kW of heat.
– Annual running bills for an average UK home: ~£600 vs £1,200 on gas.
– Savings stack up, especially on a smart electricity tariff.

A properly sized, well-installed system can cut heating costs by 40–60%. Over 20 years of service, that’s a serious saving.

Maintenance and Servicing

Annual servicing keeps your pump humming. Expect:
– Typical service cost: £100–£200 per visit.
– Megawave’s maintenance plan: £150/year, including performance checks and refrigerant health.
– Optional extended support gives you peace of mind for the lifetime of your pump.
