I used A Greener Alternative Ltd to upgrade my heating system from a gas boiler to Air Source Heat Pump, partially funded by the £7.5K government grant. The work was what I would consider to be extensive, as the heating system was relocated from an upstairs boiler cupboard to under the stairs, with upgrades to the plumbing & electrics, including a new consumer unit. I chose this company due to their great reviews & excellent customer service on the phone when I initiated contact. Every person I spoke to was professional, knowledgeable & just really nice. Huge thanks to Khalid, Ellie, Simon & Oli, who looked after me from start to finish. The whole upgrade was done in just over a week, ready for the rest of the house renovation to continue & the work was immaculate. My builder also commented on how nice the installers were. Really chuffed. Thanks for making this part of the renovation super easy & stress-free!

AGE installed our Heat Pump in 2019 and continue to service it. It has worked without fail and to our satisfaction throughout that time. I have been able to recommend them to friends, also for Heat Pumps, and those that have gone forward with installation by AGE are delighted. A strongly recommended, reliable and highly competent company with great staff.

I strongly recommend A Greener Alternative Ltd, that provided me with an Outstanding service in fixing my Air Source system, which stopped working during the recent cold period leaving me without any hot water / central heating. Upon reporting the fault an engineer attended my home within 6 hours and promptly diagnosed the fault, requiring a new flow control part (provided by Samsung). The Service Manager, Andrea, made urgent arrangements for the part to be delivered to my home and for the engineer to be available to fit the part and recommission the system. She kept me informed at every stage and demonstrated real care and went 'the extra mile' to ensure everything was done with urgency (even phoning me when not in the office to keep me updated). l was invoiced a fair sum for the services provided. I would not hesitate to recommend this company who offer outstanding customer services and whose engineers have a very good grasp of this complicated technology that offers 'green solutions'. My thanks go to the whole team but Andrea, and the engineers Lee and Oliver were superstars !!!! Best wishes John - West Sussex

Have used A Greener Alternative for the past few years for my Biomass Boiler. Andrea has always managed to fit us in and Lee has been a fantastic engineer. Thank you very much, you have saved us on many occasions.

We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
