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

Frequently asked questions

How do I know you’re properly qualified and certified to install heat pumps?

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).

Can you tell me if a heat pump is actually suitable for my home?

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.

What type and size of heat pump will you recommend for my property, and why?

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.

What will the full installation cost be, and what’s included in your quote?

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.

Can you help me access government grants like the Boiler Upgrade Scheme?

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.

How much disruption should I expect during installation, and how long does it take?

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.

Will I need to replace my radiators or upgrade anything else in my home?

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.

How noisy is the outdoor unit and where will it be installed?

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.

What warranties, servicing and aftercare do you provide?

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.

What running costs and savings can I realistically expect compared to my current boiler?

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.
