Nick installed an air source heat pump split ac system in a small badly insulated old cottage, I was concerned it wouldn’t be up to heating it since it’s old, stone, damp etc but I’m delighted it has worked a treat. It now costs about £2.80 a day to heat instead of £10 a day previously. I’m absolutely delighted. Everything was top notch, the service, knowledge, and instructions on how to use it. Recommend

Eggleton Engery have completed numerous projects for us over the last few years, including: - Full rewire, plumbing, underfloor heating, boiler, bathroom, network cabling, speaker and external wiring of 2 Bedroom Bungalow. - Dual aircon system in commercial offices. - Air source heat pump, radiators, home office wiring for our new home. 10/10 service, product knowledge and attention to detail.

Eggleton Energy installed an air source heat pump in our offices. They were quick and efficient, very quick to respond and no interruption to our business. Can highly recommend.

I contracted Hergreen Ltd to carry out all electrical and plumbing work on my Grade II home. They were incredibly knowledgeable, especially working on the complete refurbishment of a 64 room house. They rewired and re-piped the property and installed a whole new biomass system. I wouldn't hesitate to recommend them, and looking forward to working with them again.

We recently built a granny house in our garden and Nick was a one-stop shop for the full electrical installation, plumbing, under floor heating and heat pump installation. Nick was very accommodating throughout and extremely knowledgeable. He was very forthcoming with information and was able to answer our questions and queries straight off the top of his head. His work was quick, accurate and very tidy. I have also seen examples of his good work in other buildings (including a restoration) nearby to my area. Nick went above and beyond to come back to the site several times to resolve some problems - often well outside what I consider to be normal contractor working hours.

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.
