Delivery Notices (Updated March 29th 2021)

During the current situation surrounding the effects of the Coronavirus pandemic, logistics from every company are under immense pressure to deliver goods on time.
Coupled with manufacturers on reduced output due to more stringent working practices and a global shortage of component parts to supply UK manufacturing, we have taken the decision to 
temporarily limit our services rather than let our customers down amid these unprecedented circumstances.
We hope you will understand our position on this and we apologize unreservedly for the inconvenience we know it will cause.

Please note that ALL orders placed before 3:00pm are shipped same-day (subject to stock and any additional services required).
The stated transport times above have some scope for adjustment built-in for the Covid-19 situation. Carriers themselves also have their own extended workload and limitations at this time which are unfortunately beyond our control.

Orders requiring calibration 

Whilst we take the greatest care to get all orders dispatched and delivered to you in the stated time frame, orders received PM and requiring
calibration may on occasion miss dispatch that day, according to the complexity of the calibration. Be assured they will ship on the next dispatch
this in most cases should not add more than 24 hours to your delivery.

Bank/Public Holidays

Predicted delivery times are based on regular trading days Monday to Friday. Public holidays, bank holidays and weekends are outside the usual scope
of our dispatch and subject to activities/holidays of our carriers and therefore may incur additional days lead time to your order.
