** Coronavirus disease (COVID-19) Lockdown - Update May 1st 2020 **

From “On Your Doorstep” to "At Your Doorstop" – If you can’t come to us, let us come to you!

We had all hoped that we would be back to “normal” by this point but as the lockdown progresses and the government’s continued instruction for people to stay and work from home remains in place, we have decided to extend our remote support service.

Problems with technology are the last thing you want when life has become so much more digitally orientated, so we are now offering a socially distanced doorstep pickup & return service to our loyal customers. We will come to you (in PPE of course)
and collect your equipment directly from your doorstep; as per usual we will then complete a free of charge & obligation evaluation and get back to you with a quote for the work. When completed the equipment will be fully sanitised and wrapped in plastic and returned back to your doorstep.

The shop will remain closed until further notice as it is classed as non-essential retail, but we hope to offer a majority of our regular services via this method.

This is a tough time for everyone; above all else we hope that you and your families are keeping safe and well. We are here to help however we can, call us today on 07792 665 316 / 07388 317 987.
