Cai and Matt did a fantastic job at installing an Air Source Heat Pump in our old farmhouse and are such great guys. Their work is super neat, they're very knowledgeable and their support has been incredible. The system works really efficiently despite our concerns about the building being old (and heat loss). We're so so pleased we made the decision to install it and to use GreenR Renewables. We highly recommend them and hope to be working with them on a number of future projects! Thank you both!

The guys from GreenR Renewables did a fantastic job fitting our solar panels. They were quick, efficient and professional. Richard's expertise and advice really helped us decide on the right system to install. Highly recommended! Peter, Liftondown

We have worked with the team at Green R Renewables on multiple projects now and their work is always impeccable. There is a genuine care behind the installation with the customers priorities always at the forefront. We always recommend their services to our customers and will continue to do so!

Cai and his colleagues completely overhauled my Air Source Heat Pump over a year ago - this was a much needed exercise to sort out a system, and associated equipment, that had been inappropriately installed at the outset by others. Highly proficient, and technically able, they have just serviced my system; polite and tidy, the customer is advised, in layman's terms, exactly what is required and what has been undertaken. GreenR Renewables are a technically proficient, administratively able, and motivated company - in short they are thoroughly professional and, could not recommend them more highly......... Mark

Superb communication from Sarah and the team from my initial request for information all the way to a final customer completion pack containing all guarantees and information. As I wasn't around during the work I received step by step updates on how the install was progressing along with pictures showcasing great workmanship. Very professional, friendly and accommodating. Fully recommend to anyone. Thank you.

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.
