Outstanding team, highly professional and very friendly. This is the second heat pump installation they have done for me and I wouldn’t hesitate to call them again if I need a third! Fabulous.
Duncan Coventry
John recently replaced our air source heat pump. He was a recommended installer by Grant, I can see why! An outstanding service, very professional and great communication. Nothing was too much trouble despite finding problems to encounter along the way. Felt like we were in safe hands, I cannot recommend highly enough!
Nikki White
The service we received on having our new boiler fitted was second to none. Very polite guys and always cleaned up before they left for the day. I would highly recommend them for any heating and plumbing needs. I would give more stars but I can only choose 5. Thanks again.

Highly recommended! Great communication and a responsive, friendly and professional team. We upgraded our boiler, heating system and controls and received good advice and great service.

From the first contact, using the form on the easy to navigate website, to resolution I was kept informed of all progress by Emma who gave way over and above the normal customer service. John visited the following day and determined the fault and explained everything to me. He fitted the part the next day with help from other engineers due to its location, who were all friendly, personable and professional. Again, great customer service. I have had no problems since and everything is working as it should do. I will definitely use Flowtech again and would recommend them to anyone. Thank you

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.
