Martin Cooper
Installation of an EBAC air source heat pump carried out before Christmas. Cost was the same (after the grant applied) as a new gas boiler. No hard sell, kept all the existing radiators (40 years old), which I will replace over next few years anyway. Odd teething issue, which Abacus sorted quickly. A very solid and tidy installation. House is same temperature all day every day, the only other consideration is thinking ahead to boost hot water for a bath as it takes all the hot water in the cylinder but a quick boost resolved that. Happy to recommend Abacus.

Abacus have now completed an Air source heat pump Installation for me. They installed a Nibe SMO S40. This was complex and was done to replace an existing electric heating system in a stone Barn conversion. It was integrated with the existing under floor heating and radiators system and it is operating exactly as they said it would. The installation engineers arrived on time with all the equipment and completed within the projected time. They were extremely knowledgeable and adaptable and didn’t leave until they were sure it was working perfectly. Abacus dealt with all the necessary paperwork and it all went exactly as planned and on time.

No nonsense approach from Michael. Whilst other companies tried to push sub-optimal kit first, then changing their quotes, Mike came over, understood my needs, asked pertinent questions and suggested a solution. And for a decent price. Frequent communication with the office during the process. A small issue with their roofers (external company) being messy but overall positive experience.

From start to finish the Abacus team were fantastic. We are thrilled with our solar panels and would definitely recommend Abacus to anyone. We are looking forward to benefiting from reduced bills from now on.

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.
