Good price sealed units, but slow delivery
Best price online, but do not choose free delivery as this takes weeks and each delivery date was postponed.
Simple to order online and correct size delivered.

Ordered a sealed unit online as a replacement for misted bedroom window pane. Ordering was easy, and quick with plenty of options available, and the price was very competitive. Delivery was on time, and quality seems excellent, although only fitted for a few weeks.

Straight forward transaction.
Simple ordering, Unit came couple of days early, fitted fine, no fuss.
Delivery was quite long but I was made aware on ordering so not an issue.

All intact and in good time
The unit arrived all intact and on time, if unannounced and with no extra packaging, which is fine + good for the environment. All the info is on the label, no complaints either about the price. Smile

ordered 4 panels
ordered 4 panels. wait about 2 weeks for their delivery. When the delivery came, the driver told us that, unfortunately, 2 panels were broken. The driver told me that he will communicate with the office to have a replacement. The office never communicated about this, so I then contacted the office and got information that I needed to wait for the next delivery slot, which would be a 2-week delay. Waited 2 weeks, and no delivery has happened yet. Frustrated, I tried to call the number on the website, but unfortunately, I never got through this number, and the voice recorder says all the time: "all operators are busy at the moment, leave a message and we'll call you back as soon as we can". I left messages, sent emails and never got a reply. Not sure what to do. I got an upset client who cannot rent the flat because he needs an EBC certificate. I'm not sure if I'm going to the factory in person.

Hi Fiona,
Thank you for taking the time to share your feedback. We sincerely apologise for the experience you had with your order.
We're very sorry that two of your units were damaged during transit and that the replacement process took longer than expected. We completely understand how frustrating this must have been, particularly with the impact it had on your own customer and the delay to their project.
While we appreciate this experience fell well below the standard of service we aim to provide, we're pleased that your replacement units have now been delivered. We also apologise for the difficulty you experienced contacting us and for the lack of communication throughout the process. Your comments have been noted and will be shared with the relevant teams as we continue to improve both our communication and after-sales service.
We appreciate your patience and are sorry for the inconvenience caused. We hope the replacement units have now resolved the issue, and that we have the opportunity to provide you with a much smoother experience in the future.

Hi Martin,
Thank you for your feedback, and we're very sorry to hear about your experience.
We understand your frustration regarding the premium delivery service not being fulfilled as expected, and also that the refund for the additional delivery cost has not been received as promised. This is clearly not the level of service we aim to provide, and we appreciate you bringing it to our attention.
Your comments have been taken seriously and will be reviewed with the team to ensure both our delivery commitments and follow-up on refunds are handled properly going forward. If this is still unresolved, please contact us directly so we can put this right as quickly as possible.
Thank you again for your review.

Quality Units
Brilliant company to deal with, I’ve purchased many sealed units from them. They always return emails quickly and replaced a failed unit within a week. I will use them again and would always recommend 100%.

Great price and quality product
Great price and quality product. Delivered by purpose built vehicle to reduce likelihood of damage. A wee bit lacking in trying to track the progress of the order and was slightly late but I was quite remote. Overall very happy with the service.
