Shame you have to give one star, they don't deserve it. Their customer service and after sales is a complete joke, as it does not exist. Despite several attempts to contact them, they never respond.

Poor experience, …
Had solar panels and battery storage fitted by cozy energy. It took over 8 months to get any paperwork from them which means I was unable to register for export. They told be there was a backlog due to demand, but it turned out they had been suspended from their accreditation body so could not issue certification. As for the work, the team worked hard on the day of installation, but the work was sub standard and the electrical certificate was not correct either. They have had to send another company reattend twice on their behalf to make the best of a bad job.
Had I known now when I was looking to have it installed, I would’ve picked a different company

After deciding to have solar and a heat pump installed, I looked at getting some quotes in and was surprised by the lack for professional people, it was just like double glazing use to be, some people did not listen to what the customer required. Then I came across Cozy Energy, they took the time to explain everything in a way that was easy to understand, they were most helpful as I changed the requirements, and it was not a problem for then to adjust the installation.
The workmen were friendly and tidy, they took the time to explain how the system works and turned up when they said they would.
The office workers acted in a professional manor and were polite when dealing with them, overall was impressed with how the company operated and would recommend them to anyone looking to have solar or heat pump installed.
Cosy energy have been wonderful to work…
Cosy energy have been wonderful to work with and have expertly advise me on the solar and heat pump and completed an excellent installation. Very happy with the service my wife loves all the money being saved now. Thanks to Cosy team hope them all the best in the future
After nearly 2 years of fighting
After nearly 2 years of fighting, I have finally received my deposit back, having to utilise a chargeback on my credit card and go to the Financial Ombudsman.
I engaged Cozy to give me a quote for solar panels back in August 2022. I signed a contract and within a few weeks contractors turned up to fit the job.
However, as soon as they arrived, it became clear that the "survey" that had been done on our property and the subsequent quote were not fit for purpose.
The contractor advised that this had happened many times before with Cozy. We ended up in stalemate, the contractors unable to do the work, the Managing Director on the phone to my husband (being incredibly threatening, telling us we could take him to court but he would win) all trying to figure out a solution.
The solution was the contractors had to leave, and we would receive a new quote & contract.
The new quote/contract arrived, and was hugely different to the previous, less panels, panels in totally different places. I decided I had lost faith in Cozy and due to the breach of contract wanted my deposit back. That is when communication stopped.
I have written numerous letters & emails and not had any correspondence at all from Cozy.
I had to initiate a section 75 & chargeback on my credit card (thank god I paid with credit card) which I have just won (having to take it to the Financial Ombudsman). I am only sorry that my credit card company had to bail out this company and that they won't pay for their mistakes!!
Had my panels fitted last April
Had my panels fitted last April. The team were neat and tidy and quick. Took time to explain how the system worked. I had a issue with a solar panel emailed last Sunday and they sent a roofer the following Thursday who checked and a adjusted the panel
Also when choosing a solar company cozy were the first price and after a 2 year wait were still the best price
Fixing my system
So this review is a bit late coming and feel I need to give them credit they deserve. I had a solar pv system installed 2 years ago and the initial installation went really well guys were were great from start to finish. 3 weeks ago I had an issue with my inverter after a power cut which caused it to stop working. I called cozy energy to see what I needed to do and they booked an appointment to come out and got the system working again for me even though it was not there fault and done this with no charge. Thank you Cozy Energy
Pay by Credit Card
I had a solar pv installation by Cozy Energy Ltd, the installation went very well and was kept informed of progress and all done as agreed on the appointed day. However, I alerted Cozy to a problem I had with the system and despite some promises I was more or less completely ignored. I made a complaint to MCS only to discover Cozy’s registration had been suspended so made the complaint to Napit; it was only with their support that I had any contact from Cozy some six months after my initial notification. Cozy said they had reviewed the installation remotely (no need for a site inspection) and that it was working perfectly although I was able to prove this was not the case. In the end I had my system brought to correct working condition by a third party company after having made a successful claim on my credit card. Cozy’s after sales customer care is completely lacking and I regret my involvement with them.
I phoned Cozy Energy for a quote

Cozy energy
Cozy energy came to install a heat pump at my house and new cylinder and we were very happy with everything. I made contact with them as my friend had a solar pv system fitted by them last year and recommended them Cozy energy team from the start were very helpful and we placed an order. They were efficient in helping me apply for the grant and don’t a nice job of the installation and sent all documentation for me to get a discount on my electric bill. We definitely recommend
Definitely recommend to friends and family
Cozy energy completed our installation this week for our solar pv, ev charger and air source heat pump. From placing our order to finishing they were excellent and helped us with all the applications to dno and the government for the grant. The job is very neat and our friend who is a plumber has commented on the quality of their work we are extremely happy and all systems are working perfectly will definitely be recommending them to friends and family
I had a heat pump installed by cozy…
I had a heat pump installed by cozy energy for my retired mother and it is a god send to help with the heating and bill rises, the installation was seamless and Lee helped with being flexible to fit install around my mums appointments, I recommend cozy energy for being reliable and customer service
Customer quality is poor
Customer quality is poor, response time is even worse than poor. Appointments are set up and cancelled at the last minute. Our system has benn faulty since August 2022 and has yet to be resolved. No one at Cozy seems to have the technical know how to find the fault and repair it. It is a Growatt System but Cozy doesn't seem to know how to deal with it. These problems have been going on since 2022.

Try a different company
Was really happy at first! Very proactive when sorting out the instalment and efficient when it comes to payment.
Fitters did a great job..
Had mine fitted at the start of August but still waiting for the paperwork to send to my energy provider after many calls with still no joy.. if only they were efficient with the paperwork as they were taking the money
Gives the impression they don’t care after been paid
Replacement solar thermal system
So good to find someone who really knows how to work on solar thermal. Old system replaced / running in half a day.
Cozy energy highly recommend
Had cozy energy finished my installation last week from start to finish they were excellent. The office staff were great applying for my grant for the air source heat pump and installation team done a fantastic job highly recommended
Done a great job installing my ASHP
Done a great job installing my ASHP. I had a problem with the WiFi room stat. Engineer arrived promptly the next day and fixed it within 30 minutes
Reciently had my install
Reciently had my install, 14 panels, two batteries, from start to finish of install the service i experienced was so refreshing. They say customer service in the uk is a thing of the past ? Well i say try Cozy Energy !!!, and after sales with care and consideration to adjustments in fine tuning the whole set up, ie how much you force charge on cheap rate from summer to winter rates, just shows that as a company, they really do care.

Caution! Please Read!
I had the absolute misfortune getting involved with Cozy I'll go through the timeline of events so you can make you own mind up:
15 September 2022:
I had initial contact with the company, seemed very knowledgeable and we continued to discuss options. I was advised that installations were between 4 to 6 weeks, which was perfect as we were ready to go
2 November 2022:
Rec'd Final quote
9 November 2022:
I signed the contract and paid a 25% (£4,996.37) deposit
9 November 2022 to 21 December 2022
I called and emailed Cozy many times for an update, each time they said they were waiting for the DNO approval, by this date, this is 6 weeks from my order date and I was told installation would be complete by 6 weeks maximum.
- Cozy Energy were blaming the DNO for delays, and said it would be weeks until they hear from the DNO regarding approval as there are massive backlog and are taking weeks if not months to approve
21 December 2022
I called the DNO myself, who advised me they had not received an application yet from Cozy.
- After my call with DNO I received an email from DNO team that Cozy sent my application on the 21 December 2022, the DNO approved my application on the same day, so there were no delays, just a stalling tactic by Cozy. The very day I mentioned to Cozy I am in contact with the DNO, miraculously the DNO received my application from Cozy
19 January 2023 – 9.7 weeks late
No install date yet even though we were 4 weeks past the 6 week max wait promise, then Cozy energy mention I need a G100, but at this point I had a contact in the DNO who said a G100 was not necessary, and Cozy had not even submitted one anyway
6 March 2023 – 117 days, 16.7 weeks late
Told install would be done by 3 weeks today, then an email came though confirming installation would be 20th March 2023
20 March 2023
No one showed up, no one contacted me, I had calls and emails after with continued excuses from Cozy and still no installation date
24 March 2023
I'd had enough of being messed around by Cozy so I formally requested to cancel my contract and asked for my deposit back. I was advised on the phone and by email I would receive the refund in full and staff in the ‘head office’ couldn’t understand why there were delays and understood why I wanted a full refund
24 March 2023 – 27 April 2023
I constantly chased my near £5,000 deposit but the Cozy went silent on me, so I went to all social media and posted what happened, A Private phone number called me, it was Cozy as an immediate response to me going to (MSC, Police, Which, RECC, Natwest ) bank who I paid the deposit and bank with and I left HONEST reviews on Trust pilot, Facebook, Instagram, google reviews, Cozy said I’m out of my 14 day cooling off period and it is ‘tough’ I can not have the full deposit.
I explained it’s totally unacceptable and I had no trust that anyone would ever show up and I want a full refund, he mentioned that I would have to pay around £900 admin for the work they've done which I disputed. He mentioned that he'd call me 2 May with an offer as long as I removed all social media comments and reviews, which I had done until now
27 April – July 2023
I submitted a dispute in with my Bank as Cozy wwouldn't refund even after waiting for many weeks. I had to provide evidence for them to review, and Cozy had to do the same their end.
After 8 months after my initial order with Cozy, the banks between them decided to award me my deposit back in full as they saw Cozy had no right to keep it.
If you have a dispute with Cozy contact your bank, Contact MSC, Which, RECC and put all your experiences on Google, Trust Pilot, Facebook, Instagram and anywhere else they have reviews, and keep on going until you get what you need.
I look forward to the reply that Cozy give in response to my review.
