Paul “Zeus Apex” Curtis
After a bad experience with a large well known solar installation company, I decided to one more local to myself and found Volt energy. I am so glad to have found this company, they expanded my solar array and increased my storage more than doubling my system at a much better price. Lee was extremely helpful taking in board what I was after and coming up with solutions. I would highly recommend this company and I will certainly use again when I want even more and go off grid

After a particularly bright summer I started getting solar FOMO and started getting quotes from big providers for my house which has got higgledy-piggledy roofs. Without even coming to look they turned me down, but fortunately, Octopus referred me to Volt Energy. Lee came out took a look and made some great suggestions on using my garage roof, plus adding Sig battery storage to maximise night rates. Installation was a breeze and the panels look great, app is all set up and like most nerds, staring at the cost savings is my new hobby. He also moved an EV charger and sorted out lots of cabling, all tidy and on time. Would use again!

I was recommended to Lee as someone could help with a complex heating wiring system upgrade. Lee spent an hour over the phone talking me through the problem-solving method to find the solution. Full of knowledge and couldn't do enough to help me resolve. Can't rate him high enough. Top man.

Lee provided a great service for us in extending a roof mounted PV system with a second string. He kept his professional focus on the work up to and beyond completion which left us confident in his abilities and as importantly in the PV market, his commitment and reliability. Really appreciated, Mike.

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.
