What Affects the Cost?
Heat pump installation pricing in Lewisham depends on multiple factors: system type (air source vs. ground source), capacity in kilowatts, property age and insulation quality, existing boiler removal and disposal, pipework modifications needed, and electrical upgrades to support the system. Ground source systems incur significantly higher costs due to borehole drilling or ground loop installation. Urban properties in Lewisham may face space constraints affecting outdoor unit placement. Accessibility, building regulations compliance, and MCS certification requirements also influence the final quote.
Money-Saving Tips
Book surveys with multiple installers to compare quotes and system recommendations. Ensure your property has adequate insulation before installation—this maximises efficiency and reduces running costs. Ask about Boiler Upgrade Scheme grants (up to £5,000) which can significantly reduce your out-of-pocket expense for eligible installations in Lewisham.
