I was struggling to find an installer for a heat pump, did a search and RHI Heat Pumps Ltd came up. They have been brilliant and completed the work efficiently. There were a few issues with the install at first but these were resolved quickly and I now have a fully operational heat pump. I highly recommend RHI Heat Pumps Ltd.

I had RHI HEAT PUMPS finish off an air source heat pump install on my property. Was let down by previous plumbers. Guys know there stuff , fast and efficient. Got me up and running in no time . Was all signed off with guarantee, very impressed. Looking into solar install now. Will be giving Jake a ring to organise fitting and commissioning.

RHI Heat Pumps provided a detailed up-front survey and quote with no up-front fees (unlike some other companies we dealt with) and then installed a quality Windhager biomass boiler for a competitive price. The boiler was signed off by Windhager after installation, so there were no concerns about the job and six months later, we are not missing our unreliable, unsightly, environmentally unfriendly oil boiler at all.

Excellent. After being badly let done by another company, RHI Ltd responded brilliantly and managed to fit us in before the March 2022 deadline when the more advantageous money back scheme changes to a poorer one. Great fitters who overcame some of the real difficulties of fitting the system into our old house, and did so with constant good humour. RHI Ltd even arranged for an excellent company to come and put in wall insulation which is required for the money back scheme. We didn’t have to do anything! All done for us. Highly recommended.

Very pleased with the installation of our heat pump. It wasn't straight forward, as we had a recurring leak. You really get to know a company when you have a problem - especially after you have paid. RHI Heatpumps stepped up to the mark, and made sure we were 100% happy.

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.
