Adrian Tebbutt
It was great working with Chris and the team at Horisun on this large project to install Solar Thermal heating to our sailing club. We now have 600l of hot water available at all times, even in February! Chris was able to suggest improvements to our initial brief, many of which saved us money! The quality of workmanship and the neatness of the installation was exemplary. I can't recommend Chris and the Horisun team highly enough. Adrian Tebbutt, Commodore, Snettisham Beach Sailing Club

Horisun were fantastic. I contacted a number of solar installers amount our failed, old, thermal solar installation. Almost all were not interested in thermal solar. The couple of companies that were quoted very high. Horisun came up with a very reasonable quote, gave expert advice, and quickly replaced the old thermal solar panels and controller. The system is working much better than it ever did before and we have had almost constant hot water without using the boiler since spring.

Have had Chris, Jack and the team do two pieces of work, removing and refitting our solar thermal panels for some roof works and then a brand new install of a solar PV set-up. Helpful, friendly, knowledgable and really straight forward to deal with. Did what they said they were going to do; neat and tidy install and clear up afterwards. Thumbs up from me.

Great service from Chris who checked over my solar thermal system which I inherited after purchasing a new house. He explained very clearly how the system works. what to look out for in the future and was very honest in saying he didn't think the system needed a full clean. Will definitely use again when needed. Highly recommended.

Great guys. Very informative and easy to deal with. Installation was quick, stress free and very unintrusive. We are loving the benefits of our solar panels

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.
