Please note that with effect from Wednesday 21st July 2021 our new hours of trading will be 7:30 am to 3:00 pm. We will continue to work a three-day week. Our office will be open for business on Mondays, Tuesdays and Wednesdays, but will be closed on Thursdays and Fridays. We will be unable to accept any deliveries or arrange for any collections to be made on a Thursday or a Friday. Any routine telephone enquiries received on a Thursday or a Friday will be dealt with on the following Monday. However, if your enquiry is urgent you are welcome to email us, as we intend to respond to your emails as normal.

We realise these changes will cause some inconvenience but they are being forced upon us. My co-director, who is also my wife Franca, enjoys reminding me that I reached retirement age some time ago and that our working hours will have to be reduced sooner or later. Moreover, we both now have further commitments which include spending more of our time with our ailing relatives, and so I am sure you will understand the situation we are in and why these changes are necessary.

Thank you for your continued support,
