With energy prices continuing to fluctuate and more homeowners looking for sustainable ways to heat their homes, the debate around heat pump vs gas boiler has never been more relevant.
If you’re considering replacing your current heating system, you may be wondering whether a traditional gas boiler or an air source heat pump is the best investment for your property.
At Solarus Energy Ltd, based in Stockport and serving customers across Greater Manchester and the North West, we help homeowners make informed decisions about renewable energy solutions every day. In this guide, we’ll compare the costs, efficiency, environmental impact and long-term benefits of both systems.
What Is the Difference Between a Heat Pump and a Gas Boiler?
A gas boiler generates heat by burning natural gas and distributing hot water around your radiators and hot water cylinder.
An air source heat pump works differently. Rather than creating heat, it extracts heat energy from the outside air and transfers it into your home. Even when temperatures are low, modern heat pumps can efficiently capture and utilise ambient heat.
This process makes heat pumps significantly more energy efficient than conventional heating systems, often producing three to four units of heat for every unit of electricity consumed.
Energy Efficiency: Which System Performs Better?
When comparing a heat pump vs gas boiler, efficiency is one of the biggest factors.
Modern condensing gas boilers typically operate at around 90% efficiency. In simple terms, for every £1 spent on gas, approximately 90p is converted into useful heat.
Air source heat pumps can achieve efficiencies of 300-400% under the right conditions. This means they can generate three to four times more heat energy than the electricity they consume.
For homeowners looking to reduce energy consumption and future-proof their homes, heat pumps offer a clear advantage.
Running Costs: Can a Heat Pump Save You Money?
The answer depends on several factors:
- Your home’s insulation levels
- The size and design of the heating system
- Current gas and electricity prices
- Your energy usage habits
A properly designed heat pump system can significantly reduce running costs, particularly when combined with other renewable technologies.
Many of our customers choose to pair their heat pump with solar panels and battery storage, allowing them to use self-generated electricity to power their heating system and further reduce their energy bills.

Installation Costs and Government Grants
Historically, the biggest barrier to heat pump adoption has been the upfront cost.
However, government support has made renewable heating more accessible than ever.
Through the Boiler Upgrade Scheme (BUS), eligible homeowners can currently receive a grant of up to £7,500 towards the installation of an air source heat pump.
Even better, from Summer 2026, homeowners currently heating their properties with LPG, oil or coal can benefit from an enhanced Boiler Upgrade Scheme grant worth up to £9,000.
This increased support is designed to help off-grid households transition away from fossil fuels and reduce long-term heating costs.
For many homeowners, this means the cost difference between a new gas boiler and a heat pump installation is now far smaller than it was just a few years ago.

Are Heat Pumps Suitable for Older Homes?
One of the most common misconceptions is that heat pumps only work in modern new-build properties.
The reality is very different.
Many older homes throughout Stockport, Greater Manchester and the wider North West can successfully operate with an air source heat pump.
The key is ensuring the property is properly assessed and the system is correctly designed. Factors such as insulation levels, radiator sizing and heat loss calculations all play an important role.
At Solarus, every installation begins with a detailed survey to ensure the system delivers maximum efficiency and comfort.
Environmental Impact
If reducing your carbon footprint is important, a heat pump is the clear winner.
Gas boilers rely on burning fossil fuels and produce carbon emissions every time they operate.
Heat pumps use renewable energy from the air and can dramatically reduce household emissions, particularly when powered by renewable electricity.
As the UK continues its journey towards net zero, heat pumps are expected to play a major role in the future of home heating.
Heat Pumps and Solar Panels: The Perfect Combination
One of the most effective renewable energy upgrades available today is combining an air source heat pump with solar PV panels and battery storage.
During daylight hours, your solar panels generate electricity that can help power your heat pump. Any excess energy can be stored in a battery for use later in the day.
This integrated approach can significantly reduce your reliance on grid electricity while improving the overall return on investment of both technologies.
For homeowners looking to take control of their energy bills, this combination offers one of the most future-proof solutions currently available.
When Is a Gas Boiler Still the Better Choice?
While heat pumps offer many advantages, they aren’t always the right solution for every property.
A modern gas boiler may still be suitable if:
- You need the lowest possible upfront cost
- Your existing boiler system is relatively new
- Significant property upgrades would be required before installing a heat pump
- You are looking for a short-term replacement rather than a long-term energy strategy
Every property is different, which is why professional advice is so important.
Heat Pump vs Gas Boiler: The Verdict
If you’re focused on long-term savings, lower carbon emissions and future-proofing your home, an air source heat pump is often the better investment.
With government grants now available and increased support for off-grid properties through the new £9,000 Boiler Upgrade Scheme grant, there has never been a better time to explore renewable heating.
However, the right solution will always depend on your property, budget and long-term goals.
