Air Source Heat Pump
FAQs

Everything you need to know about air source heat pumps, grants and installation in Nottinghamshire and the East Midlands.

How much does an air source heat pump cost in Nottinghamshire?

The cost depends on the size of your property and the system required, but most homeowners pay a net price after deducting the £7,500 Boiler Upgrade Scheme (BUS) grant, which we apply for on your behalf. There's also 0% VAT on heat pump installations and flexible finance available. Book a free home consultation for an accurate, no-obligation quote.

What grants are available for heat pumps in 2026?

Homeowners in England can claim £7,500 through the Boiler Upgrade Scheme. Off-gas-grid properties replacing oil or LPG heating can access an enhanced grant of £9,000 from July 2026. The government's Warm Homes Plan 2026 provides further funding. We handle all grant paperwork for you and the discount comes straight off your final bill.

Are Qualis Energy MCS certified and Gas Safe registered?

Yes. We are MCS Certified, Gas Safe Registered, NAPIT Approved, a RECC member, TrustMark registered, SafeContractor approved and a Constructionline member. These accreditations mean our installations are fully compliant, grant-eligible and protected.

Which areas do you cover?

Based in Bilsthorpe, Nottinghamshire, we install across Nottinghamshire and the wider East Midlands — including Mansfield, Newark, Nottingham, Worksop, Retford, Southwell, Ollerton, Edwinstowe, Hucknall and Arnold, plus Derbyshire, Lincolnshire, Leicestershire and South Yorkshire.

Can an air source heat pump replace my oil or gas boiler?

Yes. Air source heat pumps are an ideal replacement for old gas, oil and LPG boilers, including homes off the gas grid. Our engineers carry out a full heat loss calculation, size your system precisely and identify any radiator upgrades needed. Heat pumps work with both radiators and underfloor heating and can run at up to 400% efficiency.

Do air source heat pumps work in winter and cold weather?

Yes. Modern air source heat pumps extract heat from the outside air even in sub-zero temperatures and will keep your home warm right through a UK winter. We size every system to your property's heat loss so it performs reliably on the coldest days.

How long does an air source heat pump installation take?

Most domestic installations are completed in 1–5 days, depending on the size of the system and any radiator or cylinder upgrades required. We agree a clear schedule upfront and our own engineers handle the work from start to commissioning.

Are you local heat pump installers near me?

We're based in Bilsthorpe, Nottinghamshire, with a training centre in Mansfield, and we cover Nottinghamshire and the wider East Midlands as well as installations nationwide. Towns we regularly work in include Mansfield, Newark, Worksop, Retford, Ollerton, Southwell, Hucknall, Arnold, Nottingham and Lincoln.

Do you offer servicing and maintenance after installation?

Yes. Our dedicated maintenance division provides annual heat pump and boiler servicing, unvented cylinder safety checks, reactive repairs and 365-day emergency call-out, plus service plans with remote monitoring to keep your system running at peak efficiency.
