Eljay is a fantastic company, superb communication and delivery and really excellent at what they do. They carried out an enormous amount of work at our new home and have been very quick to help on other stuff. I highly recommend them. Kev in particular was a real diamond. Thank you to all at Eljay .

Martin and his team have done some major work for me from installing solar panels and batteries, to white goods and garden lighting. Always a pleasure; team are polite, tidy and punctual. Importantly, Martin always follows up to ensure customer satisfaction. Special mention to Pete who treats your home like his own - gold standard. Thanks guys and strongly recommended!

I hardly ever write reviews about companies, but this time I felt compelled to because I am so impressed with this company. We had our electric heating replaced with a heat pump system in our house. They installed a Daikin system for us. The team worked quickly and kept everything very clean. They covered all areas with protective film where they needed to walk during the work. During the few days when we were without heating due to the installation, the weather was very cold (November), and they brought us electric heaters to keep us warm. They only replaced four radiators but checked all of them thoroughly at the end of the work. One of the radiators was leaking slightly, and they fixed it free of charge. They even relabeled the fuse box for us. They committed to a shorter timeline than other companies we contacted, and they delivered on their promise. Their pricing was also among the most competitive. Overall, I can’t think of a single thing I wasn’t satisfied with. Thank you so much for your excellent work, ElJay Energy!

From the outset it has been a good journey ... advice on the products i would need .. how its fitted ..when it would be fitted ... how much it would cost and dealing with the power companies was brilliantly executed on time and on budget by Martin and his team at ElJAY energy

It has been a pleasure having Martin and the team at Eljay install PV, battery and wiring of a new build outbuilding over the past few months. The team were professional, clean & tidy and ever quick to problem solve when niggles came up with my less than ideal environment to be working in. Comms were excellent from start to finish and flexibility on a slight pause to the project timeline when issues with the build cropped up were hugely helpful. Would not hesitate to recommend - thanks again.

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.
