Yes, you can replace a gas boiler with a heat pump, and it’s one of the most common heating switches homeowners across Kent are making right now. An air source heat pump connects into most existing radiator or underfloor heating systems, works with your hot water cylinder, and can fully take over from a gas boiler in the vast majority of homes, provided a few checks around insulation and radiator sizing are carried out first.
Is It Possible To Replace A Gas Boiler With A Heat Pump?
Yes, it is possible to replace a gas boiler with a heat pump in most Kent homes, whether detached, semi detached or terraced, as long as the property has reasonable insulation and enough outdoor space for the unit.
Air source heat pumps produce a gentler, lower temperature heat than a gas boiler, so the switch usually involves fitting an air to water heat pump that connects directly into your existing heating pipework, rather than requiring a complete overhaul of your home’s heating layout. For most households, the process is more straightforward than expected, and many homeowners are pleasantly surprised at how little disruption is involved.

What Changes When You Swap Gas For A Heat Pump?
When you swap gas for a heat pump, the change is mainly the temperature and pattern of heat produced, along with the loss of a gas connection to your property. A heat pump typically runs at a flow temperature of around 35°C to 45°C compared with roughly 70°C for a gas boiler, which means it heats your home more steadily over a longer period rather than in short, intense bursts.
Many homes also need larger or more efficient radiators fitted to make the most of this lower temperature heat, though homes with underfloor heating already installed tend to notice very little difference at all.
How Does The Process Of Replacing A Gas Boiler Work?
The process of replacing a gas boiler with a heat pump works by starting with a home survey to assess insulation, radiator sizing and the best outdoor location for the unit. From there, your installer removes the old boiler, fits the outdoor heat pump unit along with any indoor components, connects it into your existing pipework, and upgrades radiators or the hot water cylinder if needed.
Most installations across Kent take between two and three days from start to finish, and a certified installer will also handle building regulations, sign off and any grant paperwork on your behalf.
Do I Need To Keep My Old Radiators Or Cylinder?
You do not necessarily need to keep your old radiators or cylinder, as this depends entirely on whether they’re suitably sized and compatible with a heat pump’s lower flow temperature. Smaller, older radiators often get swapped for larger panel radiators to compensate for the gentler heat output, and hot water cylinders sometimes need upgrading to a size and type that works efficiently alongside a heat pump.
A proper survey beforehand will identify exactly what can stay and what needs replacing, avoiding any unexpected surprises once installation begins.
How Much Does It Cost To Replace A Gas Boiler With A Heat Pump?
Replacing a gas boiler with a heat pump typically costs between £9,000 and £15,000 before grant funding, as most gas to heat pump switches involve fitting an air to water system connected to your existing radiators and hot water setup.
Once the Boiler Upgrade Scheme grant of up to £7,500 is applied, many Kent homeowners find the net cost sits much closer to a standard boiler replacement than they initially expect. The exact figure depends on your home’s size, insulation levels and whether radiator or cylinder upgrades are needed alongside the main installation.
Are There Grants Available For Switching From Gas?
There are grants available for switching from gas, with the Boiler Upgrade Scheme offering homeowners up to £7,500 towards an air source heat pump installation. Unlike switching from oil or LPG, which qualifies for a higher grant of up to £9,000, gas boiler replacements still receive substantial support that significantly reduces the overall cost of the switch.
Heat pump installations also benefit from a 0% VAT rate when supplied and fitted together, adding a further saving on top of the grant itself.
Will Switching From Gas To A Heat Pump Save Me Money?
Switching from gas to a heat pump will save you money over time for many households, particularly once running costs, maintenance and grant funding are all factored in, though the payback period tends to be longer than switching from oil. Because gas is typically cheaper per unit than electricity, some homeowners see a more modest saving compared with those leaving oil or LPG behind, but heat pump specific electricity tariffs are helping to close this gap considerably.
Well insulated Kent homes making the switch have seen energy bill savings of up to £290 a year, alongside a significant reduction in heating related carbon emissions.
Is Switching From Gas Worth It For Landlords?
Switching from gas is worth it for landlords in Kent looking to improve a rental property’s EPC rating ahead of tightening minimum energy efficiency standards for the private rented sector.
A heat pump can boost a property’s energy performance certificate significantly, supporting higher rental value while reducing the risk of the property falling short of future compliance requirements. It also cuts down on the sort of routine gas safety checks and boiler breakdowns that tend to generate tenant complaints and unplanned costs.

Frequently Asked Questions
Can I keep my gas connection after switching to a heat pump?
You can technically keep your gas connection after switching, though most homeowners choose to disconnect it once the heat pump is fully operational to avoid ongoing standing charges.
Will switching to a heat pump affect my home’s EPC rating?
Switching to a heat pump generally improves a home’s EPC rating, as it reduces reliance on fossil fuels and can boost the property’s overall energy efficiency score.
Can I switch to a heat pump if I live in a flat with shared gas heating?
Switching to a heat pump in a flat with shared gas heating is more complex, as it often requires agreement from other leaseholders or the freeholder before individual changes can be made.
How disruptive is the installation process compared to a boiler swap?
The installation process is generally only slightly more disruptive than a standard boiler swap, mainly due to the additional time needed for the outdoor unit and any radiator upgrades.
Do I need a new boiler service contract after switching to a heat pump?
You won’t need a boiler service contract after switching, though most heat pump manufacturers recommend a service every two to three years to maintain warranty cover and efficiency.
