During these unprecedented times, we are doing our utmost to protect our customers and staff.
All engineers will have face masks, single use gloves, hand sanitiser and wipes to help keep you safe during their visit.
All they ask in return is that you keep a 2 metre distance to enable them to do their job safely and efficiently.
We want to protect our engineers too, so we have reduced the number of service visits per day in order to limit their potential exposure to the virus and we thank you for your understanding.
