Highly recommended! Certified Renewables handled our heat pump installation brilliantly. Ben provided expert advice and coordinated perfectly with our builder, while the installation crew was professional and thorough. We found the pricing competitive and the after-sales support top-tier—Ben has been very proactive in optimizing the system. Our house is warm, bills are low, and I’d definitely use them again for any future renewable projects.

Recently had a daiken Ashp installed - install went smoothly and a special mention to the installers who were polite and helpful throughout the whole installation. Price was competitive and after sales was even better. A special mention to Ben who took time out on a Sunday and came to explain and optimise the system. Sam was great also and took care of all the paperwork and grant applications. Would definitely recommend certified renewables if you are looking for Ashp.

We have been considering an air source heat pump for our home and spoke to Certified Renewable Solutions, after an initial positive discussion Ben visited my home to offer advice, suggestions and options. The whole experience was excellent, friendly, professional and above all knowledgeable with the focus on not only the installation of the system but also the tuning over time and on-going support, something I feel is essential with what for many of us are new technologies. In the end we did not proceed with an installation, the reasons for this were entirely personal but as and when we decide to proceed, I will definitely contact Ben and the team at Certified Renewables. In this is another important point at no point was there any sales pressure at all, just an informed, respectful and professional discussion. I would not normally post a review if I hadn’t proceeded with a purchase but I know many people will find themselves looking at renewable technologies uncertain of the costs and benefits. I feel it is worth saying that in my experience Certified Renewables are a very easy company to deal with, if you are considering the installation of renewables then I would have no hesitation in recommending them for an honest, knowledgeable, no pressure discussion and quote.

My experience with Certified Renewables was excellent. I first contacted them through Instagram and Ben replied to me immediately and set up a call same day to go through my options and what I would like to have fitted. Everything was very transparent in terms of pricing and the equipment choices we could have. Ben then arranged to come down and have a meeting in person before I agreed to anything - there was never any pressure to go through with anything. The team that supported us was fantastic, from the surveyors to the installation team and of course Sam in the office. Sam helped us get the whole system set up with an app and to contact our energy supplier to get the best tariffs and set up charging systems. I would highly recommend this company and their professionalism.

Ben was amazingly patient explaining the costs, efficiency and process of installing an air source heat pump. We have had it a year now and our house is warm and we have plenty of hot water. (I had my doubts!) It is very quiet and has been easy to operate. I thoroughly recommend Certified Renewable Solutions.

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.
