I am in contact with Gemini Directors, quoting, processing, factory and delivery staff on a daily basis and they are all extremely helpful, honest and looking to assist. The products are all superb and aftercare service is fantastic. Highly recommended.

AB Wreschner

We have used Gemini for all our frames manufacturing requirements for several years in the North West of England having previously tried out other suppliers. The Gemini staff are the most helpful and friendly we have dealt with, and the customer service is always 1st rate. We highly recommend this company as a trade supplier.

A highly reputable company.

They have an incredible team who are always ready to help and go above and beyond to ensure the customers needs get met.

The products are always made to perfection and on the odd occasion when things have not worked out as planned, they have always stood by their guarantees and ensured that the issues are rectified.
