We recently had an air source heat pump fitted by Puraflow, the whole experience was excellent. They are a great firm to deal with. If I had any concerns they were there to reassure me, all staff were a pleasure to deal with. I’d recommend Puraflow to anyone.

I highly recommend you avoid puraflow. They realistically acted as a sales company referring everything to different companies to do the work. There is no customer service afterwards even when things go wrong. I used the eco4 scheme and it was so rushed and badly planned. They don't show up when they say they will. A week long job takes months. And a year later I still have a leak in my roof, no heating in my kitchen, missing insulation, and a poorly designed system that therefore costs a fortune. I'm now having to contact NAPIT, Trust Mark, etc. to try and get things rectified. On installation I even had threatening phone calls from their directors pressuring me to sign completion documents. If I didn't they said I'd be liable for all the costs. Even though it wasn't completed!

I don’t really know where to start with this review. My house had no heating at all when I moved in, and as we live in the country, there is no access to gas. A heat pump seemed like a good solution. Unfortunately, since having the system installed a year ago, we have had nothing but problems. I was initially told the installation would take approximately four days. It didn’t. At first, I was told it would take an extra two days, which I was completely fine with. Then, after that, no one could come out to finish the job for over a week due to their schedule (which is not my problem). I had to move my wife and four children out of the house during the installation, as the house was completely turned upside down. Communication from the office was very poor. I constantly had to chase them for updates. The pipework was chased into the walls to an extremely poor standard. Most of the pipes have come loose from the wall, while others were not chased deep enough to be considered properly installed. Once the work was finally completed, I noticed a leak within the first couple of days. The pipes had not been soldered correctly, causing the leak. This required half of the floor to be replaced, which does not match the other half. Soon after, I kept hearing a very loud rattling coming from the pipes. The team returned, and only because I suggested it might be leftover solder did they realize the cause. Solder had been left inside the pipes, causing them to rattle loudly. Shortly after, the radiators became excessively hot. The electrician had placed something on the wrong pipe, causing false readings and making the system overheat. This issue was eventually resolved. Soon after, I had to have two new pumps fitted, as the system was still not functioning properly. The heat pump itself is very loud, and with the additional pumps, the noise throughout my house is unbearable. Certain rooms still do not heat properly. I spent a significant amount of money on this system and feel completely misled. I have made multiple attempts to contact the company via email, but have received no response for months. I recently contacted Mitsubishi to service the heat pump, but they said they could not come out due to safety concerns with it being installed on a flat roof. I now have a heat pump that is not fit for purpose and cannot be serviced. I only ever leave negative reviews as a last resort. It has been one year, and the issues are still ongoing. I sent one final email a few weeks ago giving the company the opportunity to make things right, and I have had no response. AVOID THIS COMPANY AT ALL COSTS!

Installation just completed of our air source system The plumbers and electricians have been brilliant with excellent backup from the office Very painless process. I can’t recommend the team enough. So first practical impressions the unit is bigger than I expected but only marginally The system is noisy in the cylinder cupboard but hopefully that is just whilst it initially heats the house to temperature Time will tell but excellent so far

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.
