Air Source Heat Pump in King's Lynn and West Norfolk

Heating has changed, and Gaswise is moving with it. As MCS-accredited air source heat pump installers, we are helping homeowners across King’s Lynn and West Norfolk switch to efficient, modern heating, without switching who you trust to do it – all with up to £9,000 in government grants to help cover the costs for eligible homeowners.

We are the same team you’ve called on for decades. Air source heat pumps are simply the next option on the table for anyone who wants to explore it, on their own terms and in their own time.

What is an Air Source Heat Pump?

An air source heat pump (ASHP) draws heat from the air outside and moves it indoors to warm your home and hot water, a bit like a fridge working in reverse. It runs on electricity rather than burning gas or oil, which means lower running costs and one less delivery to schedule.

It’s a straightforward swap in principle: outside unit, indoor system, and (in most homes) your existing radiators or underfloor heating stay exactly where they are.

Be energy Savvy

Being energy savvy isn’t about ripping out what works and starting again. It’s about knowing your options and making the smart call, whether that’s sticking with your current oil boiler for now, or switching to a system that heats and cools, cuts your running costs long-term, and qualifies for government grants.

It’s also about choosing the right installer. We handle the whole process for you, from checking your grant eligibility through to a reliable local installation, so you are not left working it out on your own.

MCS accredited: what that means for you

Gaswise is officially MCS (Microgeneration Certification Scheme) accredited for air source heat pump installation. In practice, that means:
We will check your eligibility and handle the paperwork as part of your survey, so you know exactly what you’re entitled to before you commit to anything.

Switching from Oil to an Air Source Heat Pump

If you are currently on oil, particularly if you are in a house or bungalow with good wall, roof and window insulation, or you have already got underfloor heating, you could be a strong candidate for an air source heat pump. Many oil-fired systems in King’s Lynn and West Norfolk convert to ASHPs with minimal disruption to the rest of the home.

We will assess your current setup during your survey and give you a straight answer on suitability, no pressure, no sales pitch, just the facts for your property.

Air Source Heat Pump Installation Cost

Every home is different, so we always confirm exact pricing after a survey. As a rough guide:

Subject to government grant approval, the customer contribution for a 3-bedroom detached bungalow in PE34 4 starts from £5,000. This covers replacing an existing oil system with an air source heat pump and compatible radiators.

See if you qualify for £9,000 off

As an MCS-certified installer, we can help you claim a £9,000 government grant towards your heat pump installation, which can cut costs by up to two-thirds.

Let us know if all three apply to you:
• You’re the homeowner
• You’re replacing an existing gas or oil boiler
• Your home has a valid Energy Performance Certificate (EPC)
