I reached out to Gensource for a sensible price on a new install for 9.9kW of Solar and a Tesla Powerwall. From the first communication it was clear I made the right choice, friendly bunch with no interest in pushing for a sale, rather they looked for a solution for us and advised on what we would need to do realise that. Following a very helpful site visit and review of what we needed and after a bit of to and fro around some skylight install happening around the same time we agreed on a solution and pushed on ahead. The guys were on site exactly when they needed to be, everything delivered bang on time and everything just went so smoothly, everyone we dealt with face to face and over the phone during the earlier stages was fantastic, friendly and keen to help us realise our goals of reducing our reliance on the grid and doing our part for the drive to Net Zero. Post installation service has been excellent also with all the post completion paperwork and details needed to get export payments on the go and following even minor queries are answered with enthusiasm and a genuine feeling of being happy to help. I cant recommend Gensource highly enough, we will certainly come back for any future needs for expansion, heat pumps or chargers.

Gensource and their sub-contractors have been excellent, courteous and friendly to all that they have come into contact with, including neighbours. The electricians went above and beyond. Work was clean and tidy. The inhouse support from the Gensource team was very helpful in aiding the small teething issues we had during commissioning. I am delighted to recommend to any potential clients/customers. A very satisfied customer.

Gensource come highly recommended from us! We had a solar panel and battery system fitted on our house recently and the whole experience has been excellent. From the initial survey and recommendations done by Gav, to the communication with Robert and the installation by the in-house team - it was all brilliant. The SolarEdge system they supplied has been working well and the whole process of scaffolding going up to completion took less than a week. If you are looking for a very professional and reliable renewables contractor you should definitely consider Gensource.

Last August, Gensource installed 16 panels, split between our East & West facing roof, a Givenergy storage battery and new EV charger. They did a brilliant job from initial quote, pre-installation surveys and finished the whole installation in one day! They were very clued up on British Safety Standards and so our inverter and battery were installed externally with a protective canopy. The guys on site were brilliant and super efficient, explaining how everything worked, including the EV Givenergy App. And the system has been running fine with no faults. We got a 25% grant and 75% interest-free loan from Home Energy Scotland as we didn't have the cash in the bank. We're now getting money back from Octopus's Smart Export Guarantee when our battery is full and we're exporting to the grid. This will bring our loan payback period to well under 7 years. Quite regularly I look at our smart meter and there is no reading as everything is coming from the solar and battery. It fills me with joy that our house at times is totally powered by the sun and this will keep going for at least 25 years. Thanks to Josh, Robert and his team for a truly grand job! Neil

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.
