I recently had the pleasure of having Keaton, Connor, and McKenzie for the installation of a new boiler, underfloor piping, and radiators in my home, and I couldn't be more impressed with their service. From start to finish, they demonstrated exceptional professionalism and skill. The installation was carried out with precision and attention to detail. Everything was done to a high standard, and it’s clear that they take pride in their work. They maintained a clean work environment throughout the entire process. I appreciated how they took the time to clean up after themselves each day, leaving my home neat and tidy. Keaton, Connor, and McKenzie kept me informed every step of the way, explaining what they were doing and any necessary updates. Their transparency made the process much smoother and less stressful. It’s evident that they work well together, creating a positive atmosphere. Their professionalism reflect well on Ivor Cook and the company as a whole. Big credit to Ivor Cook having these lads work for you. I wholeheartedly recommend Keaton, Connor, and McKenzie for any heating installation needs—1000%! They deserve all five stars for their outstanding service. Thank you, guys, for a job well done! Very much appreciated!

After reading some of the reviews and my experiences with Ivor Cook, there seems to be an ongoing trend that others and I have experienced. Ivor Cook wasn't taken on by me but was given the contract from the British Gas Nest scheme to improve my home energy efficiency and install solar panels along with other improvements. It doesn't come as a surprise that Ivor Cook will only contact you when they need to. Others comments on here kind of back up that they don't communicate well. If you ask for calls to be returned or send them emails, they simply do not respond. I had some outstanding queries that needed acknowledging and actioning (read below for these), and I had to, in the end, get British Gas to try and call them or give them a 7-day deadline to respond, or else I would have to visit their place of business for a response. Installation began and Now I assume because I wasn't paying for this, they got a little irate because my family wanted to remain in the house despite my family stating they would stay in a room out of the way. I understand that work needed to be done, and I ensured they kept well away from the workers. But I couldn't help but understand why they were so keen to try and ask us to leave, but after the shenanigans, I now understand clearly why. If they made an error or something that wouldn't be seen as acceptable there wouldn't be anyone there to judge them. The solar panels went up, and the battery and inverter were installed as needed, but the inverter wasn't installed where it was initially agreed. They had moved it further along the kitchen wall. While I was okay with this, they had to drill two large holes up and into the loft; both times they missed the loft and drilled straight into the back bedroom, scuffing the ceiling with a 200 mm long drill bit. This where things get interesting, I agreed on the last day of the solar installation I would finish early to be there to go through the setup of the data logger and app. Little did I know that Ivor Cook had installed a data logger that was being deprecated and the manufacturer would have given them the recommendation to use a newer recommend one called solarman. Anyway I left work early and Ivor Cook decided to leave early too so I wasted time leaving work for nothing. After a few unreturned calls to them I reached out to raleigh instruments who said Ivor Cook shouldn't have installed their obsolete data logger but were even more mortified when they actually inspected the logger to find the waterproof sealing gland wasn't secured tight and was just hanging there. Once it was all setup I informed my energy supplier who stated they hadn't received any certification from Ivor Cook to verify the install. it took months to get this paperwork from them and then took another 6 weeks after receiving it to be put on an export tariff. Ivor Cook went upstairs and started fishing for live wires to run the two downstairs ventilation fans they installed but, for some reason, abandoned that idea and decided what would have been a neater finish was better: running 2m of 28mm trunking around the walls despite me telling them not to, as we would be sinking the sockets into the walls once signed off and I didn't want the hassle of extra cabling. They also added a bathroom pull cord in the kitchen for the fans for the boost for some strange reason, and I got them to remove this when they came back to wire the last window fan in, or at least I thought they had, but they still hadn't wired a boost live wire from the ceiling light 0.5 m away to the fan. Ivor Cook decided to go for a hat trick, and I think this was becoming amusement for them. A 50" wide window where the fan was installed into the glass decided, rather than try to blend in the trunking by running it from corner to corner, to put a 10" piece of trunking there for the cable slapped on so quickly I wasn't sure if they were asleep or drunk, as it wasn't even straight. There was a whole lot more but google is restricting my review length, but I would seriously avoid this company.

We had solar panels installed and the whole process was smooth from survey to install. The team arrived on time, explained everything clearly, and left the site tidy. Very happy with the system and would recommend

On 20/12 one of the members of staff from this company from around 4:20 pm Parked far too close to my car and when the back van doors were opened it looked like he was hitting the car - upon going out the doors were opened to less than a few millimetres from my car so far too close I asked nicely and with pleases and all I got a load of abusive and refusal to move despite the fact the van could be moved down quite easily. This individual went into a house and came back out after a few minutes when he swung the vans doors open and it honestly looked like he’d hit my car purposely from where I was looking (a window opposite) I did shout asking this individual to stop trying to hit my car to which I got yet more abuse. I know for a fact this individual works for this company as he had the T-shirt on which I noticed that when I first asked him to move (this is how close he was to my car) Going by other reviews for this Company they are not the best and I can fully see why

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.
