With rising energy costs and greater environmental awareness, many UK homeowners are turning to sustainable heating alternatives. Air source heat pumps (ASHPs) are becoming an increasingly popular option, offering not only lower energy bills, but also long-term peace of mind and tangible environmental benefits. 

While this all sounds brilliant in theory, many people understandably want to know: how much can you actually save with an air source heat pump? And how do they perform in real households?

At Adlår, we’ve helped homeowners across the South East and beyond make the switch from traditional heating to our market-leading dual ASHP system. From reduced energy bills and improved home comfort to smaller carbon footprints, we see the financial and environmental benefits of heat pumps first-hand, every day.

In this article, we’ll share several real-life air source heat pump case studies, showing how Adlår customers are benefiting from cleaner, more efficient heating solutions — and why heat pumps are a future-ready solution for modern homes.

Why Homeowners Are Switching to ASHPs

UK homeowners are increasingly moving away from traditional gas and oil boilers in favour of air source heat pumps. In fact, the number of certified heat pump installations in the UK rose significantly between 2023 and 2024 — a trend that’s expected to continue year on year. 

There are several reasons behind this growing popularity, most of which relate to either the financial or environmental benefits of heat pumps

The Financial Benefits of Heat Pumps

The UK government’s push for low-carbon heating solutions, alongside government incentives like 0% VAT on heat pumps and the £7,500 Boiler Upgrade Scheme (BUS) grant, have made ASHPs more financially accessible than ever. These incentives significantly reduce the upfront installation cost — but this is only part of the reason why so many homeowners are making the switch. 

With rising energy costs and long-term market uncertainty, future-proofing against energy price fluctuations is a smart financial decision. Heat pumps offer a more stable energy solution, using electricity instead of gas or oil. 

Since heat pumps can be more than four times as efficient as gas boilers, homeowners also see long-term savings on energy bills, often cutting heating costs by over 30 percent. 

Plus, with fewer moving parts resulting in less wear and tear, heat pumps require minimal maintenance and tend to last significantly longer than conventional boilers, saving money on upkeep and replacement.

The Environmental Benefits of Heat Pumps

The UK has committed to reaching Net Zero by 2050, which requires a nationwide reduction in carbon emission. Installing a heat pump now allows you to contribute to meeting this goal, as well as future-proof your home against potential changes to legislation about home heating.

One of the main environmental benefits of heat pumps is their ability to reduce your carbon footprint. Heat pumps offer a cleaner, more efficient way to heat properties, using electricity to extract warmth from the outside air and convert it into usable heat — even during colder months. 

According to The Eco Experts, replacing fossil-fuel heating with a heat pump can reduce your household’s carbon emissions by several tonnes each year. While the average home could save 1,404 kg (1.4 tonnes) of CO₂ a year, those replacing older gas boilers could save as much as 2,900 kg per year.

Additionally, with a long lifespan of between 20 and 25 years, heat pumps need replacing less frequently than gas boilers too, making them more sustainable in terms of resource usage. 

A Smart Long-Term Decision

For many, the combination of cost savings, comfort, and the environmental benefits of heat pumps makes them the obvious choice for home heating.

Now, let’s explore three real-world air source heat pump case studies showing how Adlår’s system delivers real savings and comfort improvements.

Case Study 1 – A Family Home in Surrey Saves 40% on Heating Costs

Property: A 4-bedroom detached home in Farnham, Surrey

Previous System: An old gas boiler with rising gas costs

Annual Heating Bill: £1,800

The Heating Challenge

Like many families, this household faced spiralling gas costs and wanted a more sustainable solution. With increasing worries about their household carbon emissions and the state of the planet for their children’s future, they also hoped to reduce their carbon footprint.

The Adlår Heat Pump Solution

Intrigued by the environmental benefits of heat pumps, the family got in touch with Adlår. We carried out a free, no-obligation site survey, after which our team installed an 8kW air source heat pump to replace the inefficient gas system. As part of the project, we also improved insulation in key areas to ensure optimal efficiency. By taking advantage of the BUS grant, the homeowners saved £7,500 on installation costs.

The Results – Energy & Cost Savings

• Annual heating bills dropped from £1,800 to £1,080 – a 40% reduction.
• Improved home comfort with even, consistent heating.
• Estimated CO₂ emissions cut by 2.5 tonnes per year.
• System integrated with smart thermostat, offering precise control and extra savings.

Homeowner’s Feedback: “We were initially hesitant about the switch, but the cost savings and comfort improvements have been incredible. We also love knowing we’re reducing our carbon footprint.”

Case Study 2 – A Retired Couple Future-Proofs Their Home

Property: A 3-bedroom bungalow in Guildford, Surrey

Previous System: An oil-fired boiler

Annual Heating Bill: Highly variable due to unpredictable oil prices

The Heating Challenge

This retired couple wanted to reduce their dependence on oil deliveries, cut ongoing maintenance costs, and make their home more efficient for the long term.

The Adlår Heat Pump Solution

We installed a 6kW air source heat pump designed to meet the specific needs of this smaller property. To maximise performance and ensure the home was heat pump ready, we upgraded to larger radiators. The BUS grant again helped reduce upfront installation costs.

The Results – Comfort & Sustainability

• Heating costs were reduced by 35%, making bills more predictable.
• No more oil deliveries or reliance on fluctuating fuel prices.
• Lower maintenance needs and extended system lifespan.
• Whisper-quiet operation, enhancing home comfort.

Homeowner’s Feedback: “Switching from oil to a heat pump was the best decision we made. It’s quieter, more reliable, and we don’t have to worry about rising oil prices.”

Case Study 3 – A New-Build Home Maximises Energy Efficiency

Property: A 5-bedroom new-build home in Hampshire

Previous System: None (brand new construction)

Goal: An eco-friendly heating solution

The Heating Challenge

These homeowners were determined to build a sustainable, future-ready property. They wanted to integrate renewable energy from solar panels and needed a smart home-compatible system for full heating control and automation.

The Adlår Heat Pump Solution

We fitted a 12kW air source heat pump connected to underfloor heating across all floors for maximum efficiency. Integration with solar panels reduced dependency on grid electricity. The system was paired with a smart controller, allowing full app-based control and learning heat curves.

The Results – A Future-Proofed Smart Home

• Low heating bills thanks to the combination of heat pump efficiency and solar power.
• Achieved a home EPC rating of A, which benefits overall property value.
• Fully integrated Wi-Fi-controlled system, allowing the homeowners to manage heating remotely.
• Annual CO₂ emissions 3.8 tonnes lower than in their previous home.

Homeowner’s Feedback: “We wanted a home that was both high-tech and environmentally friendly. The heat pump and solar combo have exceeded our expectations!”
