I was very pleased to discover Wiltshire Energy, a local firm that specializes in renewable energy heating systems, in my case an air-source heat pump, because I prefer to use a local firm for servicing and repairs. My service was carried out thoroughly by someone who clearly knew how to maximize the system's performance (it hadn't been set up properly, and the Wiltshire Energy representative made sure it was, to optimize performance, in addition to carrying out the service). In my experience, Wiltshire Energy is also easy to deal with and very efficient, and their staff are friendly and courteous.

Wiltshire Energy recently completed an installation of a large Vaillant heat pump, a Sunamp, an array of 20+ solar panels and a 10 kw Battery. Great team. Very responsive. Very professional. A couple of teething problems that were fixed quickly. After sales has been excellent, which is so important when transitioning to a ‘new’ technology. I would thoroughly recommend the company.

Wiltshire Energy completed the install of 9 solar panels, inverter, 11.5 kWh battery and Fox ESS EV charger. The team were great from start to finish. They listened to what i wanted and talked me through the entire process. Pricing was fair and transparent and i could not recommend them more. They went above and beyond when a large cable struggle to fit into a small duct. Will certainly use again in the future as/when needed.

We had a heat pump and hot water storage tank fitted in the summer as our oil fired boiler was on its last legs. The work was carried out mostly by Keirat & Ashton but everyone involved has been very professional and helpful. There were one or two teething problems but Craig arranged for these to be sorted out and has always been on the end of a phone when we had queries.

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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
