We had shop system put in this summer by cert - The team were fantastic in the house and I love the fact that they had a female engineer. It was a pretty easy process from start to finish. We had a small issue a few weeks ago and they were incredibly responsive and just dealt with the next day giving me good advice on how to manage in the short term. I would say overall that having an air source heat pump in a 1930s house with a new extension has made a real difference, the comfort levels are off the scale, the house is just a really nice temperature all of the time and we’re not stressing about putting on a little bit of heating during the day, it also feels like it’s helped with the pockets of condensation et cetera that we used to experience, it feels like a constant temperature just makes that less of a problem. The other neat trick that I was a little bit Worried about beforehand was that the loft bedroom would be too hot as previously the loft would get quite warm while the rest of the house was cooler, that seems to have really rebalanced and this sort of thoughtful design, please as me! I’d recommend both this company and ashp (even in an older home - it works! .

We chose Clarity to install an air source heat pump and upgrade our radiators, as part of a move away from oil. We had no connection with them beforehand. We looked at other providers, but opted for Clarity because the chemistry seemed to work from our first meeting. All our dealings with them have been excellent and we are very happy to have chosen them. The work required them and us to co-ordinate with teams involved with windows, roofing and external wall insulation, and they did that in a very professional way. The work was planned carefully, the rationale for the plan was made clear and we were kept in the picture about the plan to deliver the work. They are easy to communicate with and responsive. The work itself was done by a very efficient and friendly team and the post-installation service has been very good. They worked hard to ensure that we could submit our application for the Renewable Heat Incentive. We have no hesitation in recommending them.

Very reliable company. Great work. They worked on my sons house, did a fantastic job. We will be using them when we do our whole house renovation. Clean neat and tidy just got on with their job quickly. Nice people to deal with.

Clarity have done a great job in sorting lots of issues with our boiler and underfloor heating system. ( not installed by Clarity!). Mark is really knowledgeable, efficient and professional, even helping out on a Saturday morning while on holiday! Always quick to respond, definitely our “go to” people!

Heat Pump (Air Source, air to water) installation which included changing, moving, upgrading radiators, installing new hot water tank in loft and removing the old gas boiler. Value: I have to say in terms of value for money Clarity Heating are excellent. Everything that they have installed and the time it took to do the work felt extremely good value to me. Also was able to include Govt Boiler Replacement Grant Scheme. Quality: quality of knowledge, equipment and workmanship are very high and I would recommend Clarity Heating. So far the equipment is working well with no Problems. Service: all Clarity Heating's staff were hard working, polite and careful with my property. To the point that one evening they stayed particularly late to ensure that the new water tank (in the loft) was safe and would not leak once filled and tested. I would say the one challenge was that living with the work going on was hard. Understandable the workers were not always ready to do a full clean and tidy between working days which meant there was some cleaning each day to make parts of the house feel homely. They all work face coverings throughout all work which was greatly appreciated. Communication: mostly good but sometimes we needed to chase to find out which days they would be coming or times they would arrive. Worries: Changing from conventional gas boiler to ASHP was a worry but felt in good hands and had good explanation of use. Also moving from combi boiler to refit tank fed hot water was a concern but in reality is actually better than what we had before and all explained really well. Would I use again or recommend? Yes definitely, thanks for all efforts Clarity Heating.

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.
