How much does an air source heat pump cost in Northamptonshire?
A typical air-to-water air source heat pump installation in Northamptonshire costs between £8,000 and £14,000 before grants, depending on property size, heat loss and whether radiators or pipework need upgrading. The £7,500 Boiler Upgrade Scheme grant is deducted from that figure, so most homeowners pay between £500 and £6,500. Air-to-air systems start lower, from around £3,000.
Do you handle the Boiler Upgrade Scheme grant application?
Yes. As an MCS certified installer we apply for the £7,500 BUS grant on your behalf and deduct it from your quote, so you never pay the full amount upfront. We also check whether you qualify for ECO4, West Northamptonshire or North Northamptonshire council funding.
Will a heat pump work in an older Northamptonshire home?
Most Northamptonshire homes are suitable, including Victorian terraces and 1930s semis, provided insulation is reasonable and radiators are correctly sized. Where a property needs improvement, we design the system around it or recommend a hybrid setup that pairs a heat pump with your existing boiler.
How long does installation take?
The physical installation usually takes one to three days. End to end, from first survey to a commissioned system, expect two to six weeks, mostly accounting for the survey, system design and grant processing.
Are you MCS certified?
Yes. Northants Heat Pumps is an MCS certified installer, which is a legal requirement for accessing the Boiler Upgrade Scheme grant. All work is carried out to MCS standards and covered by our workmanship guarantee.
