    Fantastic service and great install, my bills are very low and the house is always warm, they handled all the paperwork, I did not have to do anything!

    Fantastic experience! The installation was smooth, and the team explained the system clearly. My home is now consistently warm, and I've noticed lower energy bills already.

    Exceptional Heat Pump Installation. I cannot recommend the team at Casa Renewables highly enough. The entire process was seamless, professional, and genuinely exceeded our expectations.

    Lucy Sulman

    Acassio installed and has since carried out an annual service on my air source heat pump. He is polite, knowledgeable and takes the time to explain how the system works.

    Lawrence Baker

    We recently had an air source heat pump installed by Acacio and his team. They came all the way from London, and this company sets a new standard for professionalism.

    Moving to a heat pump with Casa Renewables was a brilliant decision for our London Flat. Their customer support was excellent. Highly professional and strongly recommended!

    A Heating System That Pays for Itself

    An air source heat pump works by extracting renewable warmth from the outdoor air, even on the coldest days, and channelling it directly into your radiators and hot water system. It replaces your gas boiler, oil-fired boiler, or electric heaters with a single, high-efficiency HVAC system, delivering significant savings on your energy bills from day one.

    • Claim up to £7,500 through the government's Boiler Upgrade Scheme, including oil-fired boiler replacement grants
    • Households replacing electric storage heaters typically save between £700 and £1,200 a year on heating bills. Savings against a gas boiler are smaller and depend on the age and efficiency of your existing boiler, your electricity tariff and your home's insulation, the Energy Saving Trust estimates around £260 a year against an older G-rated boiler. We provide a property-specific estimate at survey.
    • Reduce your home's CO₂ emissions by as much as 44%
    • Three to five times more efficient than any conventional central heating system
    • Operates reliably in temperatures as low as -25°C, with no supplementary heating required

    Sources and assumptions: figures are indicative annual heating cost savings for a typical UK home, based on Energy Saving Trust guidance. Actual savings depend on your existing heating system and its age and efficiency, your electricity and fuel tariffs, your home's insulation, and how you use your heating. We provide a property-specific estimate at survey.

    What You Could Actually Save

    Savings depend entirely on the system you are replacing. Here is an honest comparison rather than a single headline number.

    Electric storage heaters

    £700 to £1,200 a year

    Largest savings, electric heating is the most expensive way to heat a home

    Oil-fired boiler

    Varies by property

    Depends on oil prices, boiler age, and your electricity tariff

    Older G-rated gas boiler

    Around £260 a year

    Energy Saving Trust estimate for a typical home

    Modern A-rated gas boiler

    Little to no saving

    Running costs are broadly comparable, benefits are mainly carbon and comfort
