New Normal - New Rules……

As you may have seen from our last update the branch will be back open as of June 15th, however the safety of our customers and co-workers remains the highest priority so there will be a few changes to the regular service. We’ve introduced new measures so you can enjoy a safe and comfortable visit.

New Opening Times

 From June 15th we will be implementing a new set of Branch Opening Hours:

 Weekdays will now be 10:00 – 12:00 / 13:00 – 17:00 and we will no longer open on a Saturday.

 We have made the adjustments to allow time in the morning and evening to sanitise and clean the branch & equipment ready for the day and also to allow time for collection and returns as we appreciate that many customers may still fell hesitant about venturing out just yet. We have decided to run the very popular and FREE OF CHARGE Collect / Return Service indefinitely for your convenience.

 We will however still try and answer the phone or text messages outside these hours.

 One Customer at a Time

 Sadly we are not blessed with massive amounts of space in branch so to maintain social distancing guidelines and allow customers to feel safe and comfortable we will only be allowing one customer (or maximum of 2 people if from the same Bubble) into the branch at the same time.

Inbound Desk

 We have designated the Reception Counter as the Inbound / Outbound drop off area. Please place your equipment on this desktop only. It will be continually sanitised throughout the day and any work coming in or going back out will also be sanitised. 


 We are still accepting payments either via Cash or BACS Transfer.

 With these measures in place we hope to offer and safe and comfortable environment to our Customers and Staff and look forward to seeing you soon!
