Thank you for your review.

We're pleased to hear that you were happy with the quality of the installation itself. However, we're sorry to read your comments regarding the front door being left open during the installation. That is not the standard we expect from our installation teams, and we will raise this with those involved.

With regard to your after-sales information, your system was commissioned on 16 July. In line with industry standards, the handover pack is typically issued within two weeks of commissioning, and we are pleased to confirm that your handover pack was sent two days ago, well within that timeframe.

We have also notified your Distribution Network Operator (DNO) of the installation. The only outstanding item is the export MPAN, which is issued by your electricity network operator and is unfortunately outside our control. Once this has been allocated, we will be happy to assist you with changing to the most appropriate electricity tariff so that you can maximise the benefits of your new system.

We appreciate your feedback and will ensure your comments regarding site security are addressed with our installation team.

Kind regards,
Zest Energy Ltd

Hi Ian,

Thank you for your feedback.

We have reviewed our records and do not recognise the sequence of events described in your review.

We have not made any marketing calls to you this year. The call made today was a courtesy call to offer existing customers a complimentary health check of their system and was not a sales call.

We also have no record of repeatedly contacting you after requests to stop or of changing telephone numbers to circumvent call blocking. Those allegations are inconsistent with our records and with the way we conduct our business.

We have nevertheless updated your record to ensure that you receive no further telephone contact from us.

We would ask that you reconsider the wording of your review so that it accurately reflects the nature of the contact you received.

Kind regards,

Zest Energy

Thank you for your review.

We are sorry that your father was dissatisfied with his experience and we acknowledge that the refund took longer than it should have. The deposit has since been refunded in full and we apologised for the administrative error that contributed to the delay.

However, we do not accept your comments regarding the quotation. The proposal was produced using OpenSolar, an industry-standard design platform that includes dedicated functionality for retrofit systems and clearly sets out the assumptions and calculations used to produce the projected figures. These assumptions are available within the proposal for the customer to review before making any decision.

We reject any suggestion that the proposal was intentionally misleading or that Zest Energy acted improperly. No installation took place and your father exercised his right to cancel before any work commenced.

We always welcome constructive feedback and remain committed to providing accurate information and a professional service to all of our customers.

Thank you for your review.

We are disappointed by your comments, particularly as they do not reflect what actually occurred.

The installation itself was completed professionally, which you acknowledge in your review, and we appreciate your comments regarding our installer.

The issue arose because you refused to make the final payment in accordance with our agreed terms and conditions, stating that you wished to wait until you had received access to the monitoring app. Although the only problem was that the registration had initially been completed using yahoo.com instead of yahoo.co.uk, we advised you that this was a minor administrative issue that would be corrected. We also confirmed that we were happy to wait for payment until your app access had been resolved, despite payment already being due under our contract.

Given those circumstances, we believe your comments about our conduct are unfair and do not accurately represent the way this matter was handled. We made every effort to resolve a straightforward issue amicably and without dispute.

We remain available to assist if you require any further support with your system.

Hi Laura,

We're sorry to read your review.

Following your recent contact with us, we've identified that the CT clamp requires adjustment. This component measures the flow of electricity through your property and is essential for the battery to operate correctly. An engineer has already been arranged to attend within the next couple of days to make this adjustment.

Until this work has been completed, it isn't possible to assess the system's performance or the savings it is capable of delivering. We therefore feel it would be premature to conclude that the battery has not delivered the expected benefits.

We remain committed to resolving this as quickly as possible and look forward to getting everything operating as intended. Once the adjustment has been made, we'll be happy to review the system's performance with you.

Hi Martin,

We're sorry to hear about your experience.

However, we believe this review has been posted on the wrong company's profile. Zest Energy Ltd (zestenergy.net) is a solar and renewable energy installer and does not operate a public EV charging network or process EV charging payments.

From the details you've provided regarding EV charging and £40 pre-authorisations, it appears your review relates to Zest (zest.uk.com), which is a separate, unrelated business.

If this is the case, we'd be grateful if you could remove this review from our profile and repost it on the correct company's Trustpilot page so they can investigate your experience and assist you.

Many thanks for your understanding.

Kind regards,

Zest Energy Ltd

Thank you for your feedback.

We are sorry that your experience did not meet your expectations. We appreciate that delays in processing a refund can be frustrating, and we apologise for the level of communication you experienced while this matter was being resolved.

The refund has now been processed and returned. We continually review our internal processes to improve both response times and customer communication, particularly during periods when key members of staff are unavailable.

We wish your father-in-law all the best and thank you for taking the time to share your feedback.

Hi Alan,

Thank you for your review. We're sorry to hear that you were dissatisfied with your experience.

To provide some context, your installation was completed on the agreed date. Unfortunately, our installer was involved in an accident with a company vehicle and had to use alternative transport in order to avoid postponing your installation. As he had limited space available, he was unable to remove the remaining packaging and unused equipment on the day. This was explained to you at the time, and we subsequently contacted our supplier to assist with arranging collection.

With regard to the scaffolding, we use an independent scaffolding contractor and you were advised that scaffolding arrangements were being made ahead of the installation. As customers do not generally need to be present when scaffolding is erected, the contractor schedules these works directly as part of the installation process.

We appreciate that changes to schedules and unforeseen circumstances can be frustrating. However, we worked hard to ensure your installation proceeded as planned despite the vehicle incident and communicated the reasons why some materials remained temporarily on site.

We take all customer feedback seriously and will continue to review our processes to ensure the best possible customer experience.

Kind regards,

Zest Energy Ltd

Hi Kevin,

We note that this review appears to repeat concerns first raised in 2023 following your installation.

At the time, we thoroughly investigated the matters you raised regarding the specification and performance of your solar PV system. The inverter installed was selected as part of the system design and was fully compatible with the installed equipment and intended operation of the system. We did not find any evidence that the system had been mis-sold.

We also note that comparisons between retail component prices and the total contract value of a professionally installed renewable energy system do not reflect the full scope of works provided. Project costs include system design, installation labour, electrical testing and certification, scaffolding where required, commissioning, warranty support, insurance, administration, and ongoing customer support.

We appreciate that you remain dissatisfied with our conclusions. However, as this matter was reviewed extensively following your original complaint, our position remains unchanged.

Should you wish to discuss any current operational issues with your system, our customer support team remains available to assist.

Kind regards,
Zest Energy
