Really good service and the job was spot on! Will be using these from now on.
Martin Griffiths
Oliver and his colleagues came to do a Gas Fire Service - they were great! Were able to get a 12 year old fire working properly and checked over in good time, they were polite, efficient and down to earth and quoted a very reasonable price for the job! Would definitely use them again for other gas related works.

Excellent service from Oliver, Rob and the team. Had a boiler service, new column radiators fitted, powerflush of the system and an old woodburner removed. All well priced. The guys kept me up to date throughout. Will definitely use them again.

Thermagas were fantastic from start to finish. Our boiler was 20+ years old and with absolutely no idea where to start in terms of getting it replaced, they helped us pick our new boiler while explaining more than enough why they had chose said boiler to suit our home and needs. They turned up on time, well prepped, and got straight to it. Within just a day and a half our new boiler was on the wall fully installed, commissioned, and warranty’s activated. They even built a cover for the pipework and re fitted our bathroom accessories which had to move due to the magna clean filter they fitted to help keep our system clean. Couldn’t have been more happy and will be using and referring for any issues going forward.

Cliff & Oliver were the only team that could fix my boiler at an affordable cost. They went above and beyond, were quick to respond and excellent tradesman. I would highly recommend! It’s hard to find decent tradesman these days we can trust. Well deserved 5 stars!!

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.
