Coronavirus – Enforced Business Lockdown

Notice to all Valued Customers

As we all know, the pace of change regarding all things associated with the Coronavirus, and its containment, has been startling with many comments and some guidance being contradictory to say the least.

Therefore, after much deliberation and considering the general reaction within our industry coupled with the fact that the vast majority of our major suppliers have already closed, we have taken the decision to shut down our operations with effect from Friday 27 March. It is difficult to be specific regarding the anticipated date we will re-open, but current information suggests that key suppliers are targeting to re-open around the 14th of April. If they do so, we will also re-open around that date as well.

This decision has not been taken without much sole searching, but the wellbeing and health and safety of all our staff and customers is of critical importance to us, so we feel that it is the right thing to do at this very difficult time.

The timing of this decision means that all jobs due for collection or delivery on, or before, Friday 27th will be completed and our yard will be open for all collections up to 4pm on Friday 27th.

Any jobs that were due for completion for Monday 30th onwards have been placed on hold and remain so until we have confirmation of a return date and that the job is still required.  We realise that this will mean that many customers will have jobs on order that will not be fulfilled before the enforced closure, but we would like to reassure everyone that once we are all given the green light to start up operations again, we will have everything in place and ready to be able to support you and your business going forward.

We would like to take this opportunity that thank you for your continued support, and we hope that you, your staff, and family, keep safe during the difficult few weeks we all have ahead of us.

All emails will still be picked up so please use the [email protected] email address.

Best wishes
