Written by the company
Zing Energy designs and delivers complete renewable energy systems that are built around each property, its energy use, and the people who rely on it. We support businesses, public sector partners, housing providers, and residents with practical energy projects that are carefully assessed, clearly managed, and properly completed. Our approach starts with understanding the site, the customer’s needs and how energy is used day to day. From there, we specify the right system, manage the installation with care, and make sure compliance, certification, documentation, and handover are handled properly. For organisations, that means a reliable project partner focused on lower operating costs, reduced reliance on grid energy, and long-term value. For residents and end users, it means clear communication, respectful work in and around their property, and support from a team that understands installation work affects real homes and routines. Zing Energy focuses on doing the right work properly: survey-led recommendations, managed delivery, quality workmanship, and a smoother experience from first conversation to final handover documentation.

Thank you for taking the time to leave such a glowing review, Marie.
We really believe that making small adjustments to meet the needs of people living and/or working in the properties we’re visiting can make a big difference. So, it’s wonderful to see that the team’s effort has been appreciated.
Your kind words will be passed on to the installation team!
Zing operators lie and don't care about customers
You didn't tell me when they would be arriving, or how many even though I explained my illnesses to you. You told me one thing was happening then the workers turned up to do something totally different. I wouldn't recommend you to anyone. Your call operators do nothing but lie and aren't helpful at all.

We’re sorry to read this, as this does not reflect the standard of communication we aim to provide.
We can confirm that appointment notifications were issued in advance, including a call and reminder text, so that you were aware of the visit and the works planned. We also understand that the misunderstanding around the team’s arrival and the work being carried out was resolved on the same day.
We appreciate that this was still a frustrating experience for you, but we do want to clarify that information was provided and the matter was addressed at the time. Again, we are sorry for the frustration caused. We appreciate your feedback and will take it into account as we continue to refine our communication procedures with customers and tenants.

Once installation is done you’re on your own
Just moved into a property that had the solar and heat pump installation through a government grant two years ago.
I am astonished that the installation was approved by the person in charge as it is absolutely awful.
Radiator pipework has been drilled through an existing architrave and then connected to the radiator at the top and bottom instead of it just being at the bottom.
The water tank is far too large for the cupboard in which it is installed so the doors cannot close and are permanently open.
The system has had a leak in the loft for a while and only noticed because no there’s a hole in the ceiling.
Electrics inside the cupboard have just been connected into a junction box and left laying on the water tank.
I contacted Zing to see if the install could be moved into the garage as every other property in my close has had done and was told no. The previous owner had agreed the install and signed it off and as far as they’re concerned it’s not their issue.
Well if getting someone close to 70 years of age to agree on an install that is so not appropriate for the property is their only back up then I would avoid Zing at all costs.
Indeed I would go as far to say that their contracts to install any grant related work should be taken from them and never be reinstated.
I have tried several local contractors and none of them want to touch the install.
Following this post I received a response from Zing clarifying the installation date and that no concerns were raised at the time regarding the installation.
That does not absolve you from installing a system that has glaring no no’s. I have been in various trades over the years and none workman I have ever worked with would have carried out work in the manner it has in this house.
If the previous owner was told that the installation had to be done that way why would she have questioned it?
The hot water cylinder is too large for the cupboard in which you installed it. Why has this been done and not queried by the contractor, not the customer?
There is a radiator with its pipes drilled through the architrave at an angle at two separate heights. Why was this approved by the company?
It seems to me that Zing employed sub contractors with little or no experience in installations.
Nobody from Zing would have been to the property to sign off any works and if they did then they are complicit in this mess as much as the contractor who installed it.
Any company worth anything should rely on its reputation for quality work, not rely on the fact that nobody queried it before the warranty period expired.

We are sorry to read this and appreciate you taking the time to share your concerns.
To clarify, this installation was completed in January 2023 and was signed off at the time, with no issues reported to us during the workmanship warranty period.
We understand you contacted us recently regarding the location of the unit and a leak in the loft. As these concerns were raised outside of our workmanship warranty period, we explained that we were not in a position to carry out further works and recommended contacting a qualified local engineer or contractor to inspect the system and advise on the best course of action. Ongoing servicing and maintenance are also important in identifying and preventing issues over time.
We appreciate that this may be frustrating. However, we do want to ensure the situation is represented accurately. If you would like to discuss the matter further, please contact us directly and we will be happy to review the correspondence with you.

We hope you enjoy the benefits of your new solar setup. Imagine how great they’ll work when we see some sun again!
Have a very merry Christmas and a happy new year.
Happy with the workers and the job they’ve done
Happy with the workers at my home. Quieter and politer than blokes on a roof can be expected to be in the miserably cold weather. The solar panels will take some getting used to but everyone’s in the same boat and they’ll my bills easier so I’m very pleased.

Thanks so much for the kind words. We’ll pass them on to the team.
They’ll be chuffed to hear their efforts were appreciated, especially working through the cold in the chilly autumn months. And you’re right - solar can take a little getting used to but it’s a great step toward lower bills and a greener home.
Wishing you a warm and worry free Christmas!

Zing went the strings of my heart.
Everything from the my initial application has gone smoothly. Zing were polite, efficient and everything went along smoothly, they organized a surveyor to the property to evaluate what and where installation was needed. They informed me when installation was due and this was prompt. Their contracting team of craftsmen including Gas fitters, Electricians roofers etc were all first class. I would highly recommend Zing as a company. You can’t get better.

Thanks for the 5 stars, Rob. It made the team’s day.
These jobs only work when everyone pulls together - surveyors, office, fitters, compliance - so it’s great to hear it all clicked for you.
Our Customer Experience crew asked me to pass on a thank-you right back: you were a pleasure to work with from first call to sign-off.
Heat Air Pump
I contacted Zing on 02/10/2025, after my heat air pump had been serviced, with some issues highlighted in the engineer's report. The Air Pump was not level, some wires inside had not been correctly dealt with and the hole through the wall had not been filled in correctly.
All these issues have now been sorted to my satisfaction.

Zing installed an Air source heat pump…
Zing installed an Air source heat pump and solar panels at my mother's property. Properties need to be well insulated for this type of system to work economically. They identified at the outset that there may be a need for further roof insulation. No additional insulation was provided even though there is clearly a need for it. Trying to get an answer from them was difficult and the last piece of advice they gave was to contact some local company to provide the insulation. I've tried doing this ie contacting a local company but I've had no joy with the most local outfit saying they were just inundated with work. So, I am left in limbo and another autumn and winter is fast approaching.

Thanks for reaching out. We’re sorry to hear you’re worried about energy bills with autumn and winter approaching.
Under the ECO scheme, we installed every grant-funded measure we could in November 2023 - including your air-source heat pump and solar panels. The loft insulation at the property met the scheme’s minimum criteria, so the top-up we recommended to optimise efficiency isn’t covered by funding.
We’re willing to take on this additional work, but distance and overheads would make it disproportionately costly for you, so we suggested local specialists to keep the price down. We’re sorry if that reasoning wasn’t clear at the time.
Next step: It’s disappointing that local suppliers have remained fully booked. If that’s still the case, we’re happy to step back in and arrange the work ourselves.
Please drop us a line at enquiries@wearezing.com or call 0330 808 4365 with your installation reference, and we’ll do everything we can to give your mum some reassurance before the cold sets in.
Making homes warmer and cheaper to run is what we’re here for, and we’d love the chance to finish this to your satisfaction.

Hi Natalie. Thank you for raising your concerns.
Where things stand:
We don’t take payment at this early stage. Our Accounts and Customer Experience teams have double-checked every record and see no sign that any payment has been taken.
As we discussed by phone, we’re waiting for the proof of payment you mentioned (e.g. a statement or receipt). With that, we can trace the transaction and refund it immediately if it’s linked to us or an approved partner.
Next steps
Once we receive your evidence, we’ll finish the investigation and call you with the outcome.
Separately, we’re rolling out clearer milestone updates so every customer can follow the timeline from grant application to installation. We know the process can feel slow, and we’re committed to making it more transparent.
Thanks for your patience while we get to the bottom of this. We’ll update this reply as soon as we have the facts.
Very hard working and a good job done
I had External Wall Insulation, Solar panels, a heat-pump and boiler installed. I was not expecting a great service/job based on passed experience with various types of labourers, but the quality of work with Zing restored my faith that there are very good workers out there. They all worked like Trojans and did an excellent job.

The people and workers are great no…
The people and workers are great no complaints. It was extremely long hours for them and us and because they were pulled off my house to do another maybe the standard of workmanship suffered. The plastering wasn't great and the skirting boards were just straight bits of wood as opposed to matching them in. Two of my light fittings were broken and they did not replace them but did fit the new ones I bought for free. The problem was after, the heat source is so slow to heat the radiators they did not sign off the solar panels and I am still waiting for EDF to recognise my panels. That bit could have been explained or had help with to do all that. It's expensive to run this system and I haven't been able to use it on benefits.£30 for 9 days. I'm sat here with a hot water bottle just like I did before it was installed. I got it done because of future house sale.

Had solar panel, loft and interior insulation, heat pumps fitted. Although a lot of upheaval at the time, work completed in 8 working days. Every team - plasterers, plumbers, electricians, loft insulation, office admin, rubbish collectors have been brilliant, they all work incredibly long hours and are very professional, good rapport with everyone, excellent communication throughout, would highly recommend.
