AEI Systems

To all our valued Suppliers and Customers

As a result of the impact of the coronavirus pandemic and the Government lock-down on non-key industries we have taken the decision to temporarily suspend operations for a three week period with a return to work date of Tuesday 14th April 2020. Unfortunately we will not be able to accept deliveries during this period.

We sincerely apologise to all our highly valued suppliers and customers for any inconvenience this might cause and look forward to a safe and healthy return to work in due course.
