We have really enjoyed working with these guys. From the initial assessment through to getting everything fitted. It has been very professional and a positive experience. We would definitely recommend anyone getting in touch to see if they are eligible. We are going to have an open house afternoon for people to come round and see it and talk to a representative.

Highly recommend. From start to finish Stellar energy were brilliant. Covered all aspects From the first phone call. Came out to my house to see what needed doing. After 3 months had solar panels, air source heat pump and radiators, internal wall insulation (insulation/boarded&skimmed), Loft insulation, all installed. The Grant has made a massive difference to the house and will help save money on my gas & Electric bills. They literally cover everything if your thinking of upgrades on your home get in touch with Stellar Energy.

The boys did a good job up until the end, the extractor fan cover broke, and they thought it would be a good idea to get the wrong one and silicone it on like as If I would never find out. I would've given 5 stars otherwise. Very disappointing. I would rather them be honest and say it doesnt fit then try and fit it incorrectly making it difficult to access the settings for the extractor fan. Update: they got in touch and rectified the issue. Thanks

Dan and Martin were brilliant throughout the day! Really appreciated them being patient with me while I asked all my questions, and took the time to explain what they were doing when i had a concern. Work done was high quality, and they did an excellent job of cleaning up afterwards. Thanks very much Dan and Martin :)

Jack and Dan came to my house to install trickle vents and an extractor fan in the bathroom. They were professional and considerate and explained the work being carried out. They answered any questions that I had. I hope the team that complete the insulation install are just like these two. 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.
