As homeowners in Putney, many of us are weighing up our options when it comes to heating. Rising energy prices, government targets on decarbonisation, and the need for better home efficiency mean that the old “like-for-like boiler swap” isn’t always the best answer anymore. More residents are asking about renewable heating in Putney and whether it’s worth switching from a traditional gas boiler to a modern heat pump.
In this guide, we’ll compare heat pumps and gas boilers for 2025—covering costs, installation requirements, running costs, and the SW15 EPC impact on your home.

Heat Pumps Vs Gas Boilers: The Key 2025 Comparison
What Are Heat Pumps And How Do They Work?
Heat pumps, particularly air source systems, draw warmth from the outside air and use electricity to boost it to a usable temperature. Instead of burning fuel, they transfer heat, making them highly efficient and low in carbon emissions.
For many Putney households, the first concern is the cost of the air source heat pump in Putney. While upfront installation is higher compared to a boiler, incentives such as the Boiler Upgrade Scheme (BUS) and other green heating incentives can make the switch far more affordable.
What Are Gas Boilers And Why Are They Still Popular?
Gas boilers have been the standard in UK homes for decades. They heat water quickly and provide a strong output, which is why many homeowners still trust them.
When it comes to gas boiler efficiency, modern condensing boilers can reach over 90%. However, gas remains a fossil fuel, and with energy policies shifting, long-term reliance may not be the most sustainable option.
What Are The Running Costs Of Each System?
When comparing running costs, the answer depends on several factors:
- Gas boilers: Gas is still cheaper per unit than electricity in the UK, meaning short-term running costs can be lower.
- Heat pumps: They use less energy to deliver the same heat. With higher efficiency, they can offset electricity costs—especially if paired with solar panels.
For Putney residents, where property types vary widely, the best solution often comes down to insulation and household demand.
What Are The Installation Requirements For Both Options?
Heat pumps: These require outdoor space for the unit and sound insulation to perform at their best. We often help clients understand whether their property is heat-pump ready during a home survey.
Gas boilers: Replacements are generally quicker and cheaper to install. However, government targets may phase them out, so this should be factored into long-term planning.
Our experienced Putney heating engineer team can assess your property and recommend the most practical path—whether that’s a heating system upgrade in Putney or a complete move to renewable technology.
What Is The SW15 EPC Impact On Your Home Value?
Energy Performance Certificates (EPCs) are a significant factor in property value.
A home with a high-efficiency boiler may see some improvement, but a heat pump installation has a more substantial SW15 EPC impact, boosting ratings significantly.
With landlords facing stricter rental requirements, installing SW15 boiler alternatives in Putney now could save you hassle later.
What Are The Green Heating Incentives Available?
Putney homeowners can benefit from a range of green heating incentives, including:
- The Boiler Upgrade Scheme (up to £7,500 off a heat pump)
- Local grants supporting energy efficiency improvements
- VAT reductions on renewable systems
When looking at the cost of air source heat pumps in Putney, these schemes make a significant difference.
Why Upgrading Your Heating System Is A Smart Move In 2025
With 2025 marking the turning point in energy policy, the government is making it clear that new installations of fossil-fuel systems will be phased down, while support for renewables will increase. For homeowners considering long-term savings, sustainability, and property value, why upgrading your heating system is a smart move in 2025 is a question worth exploring.
