Re service 13 Aug 24. Booking was very straight forward and they managed to fit me in at short notice. Mike the Service Engineer arrived as scheduled and undertook the work in a very professional manner. The works were undertaken without fuss and the property left in a clean and tidy state. Highly recommend this company

Excellent service. I was recommended by a friend and they came out within 12 hours, rectified the issue, did a service, tested my smoke alarms and installed a carbon monoxide sensor. Very friendly and professional both office staff and Fred who did the work. Very happy and have already recommended them.

Recently had an external boiler fitted. From quote to completion, the staff were very, professional, tidy, friendly very helpful. The guys that carried out the installation were also very considerate and accommodating and the work carried out to a high standard. We will definitely recommend this company. Cheers from Rich and Chris

An engineer called Billy attended our house when we had a leak from a pipe coming from our oil tank. Sadly the tank had to be condemned and it turned out our immersion heater had gone too so we had no hot water or heating!. The company were very responsive and had Billy return a few hours later to change the element in the hot tank. They also arranged to attend the next day to change the oil tank. All in all, a great service, well executed. Billy, was nice to meet you.

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.
