COVID-19 Secure - Our Robust Business Procedures

In response to the current COVID-19 (Coronavirus) pandemic we have implemented several changes to our procedures so we can continue providing our service and products to our valued customers.

The World Health Organisation (WHO) advise that the likelihood of an infected person contaminating commercial goods is low. The risk of catching COVID-19 from a package that has travelled and has been exposed to different conditions and temperatures is also low.

Miss Kerry Harnes (CEO) has taken on the responsibility of our COVID-19 strategy to ensure we are compliant and secure. Below is a summary of the steps we are taking to keep our staff, their families and our customers safe. These procedures are under constant review, but so far they are working and everyone at Mr Memory is in good health!

Our COVID-19 policy has been reviewed and adjusted to meet localised government tier restrictions
Strict social distancing - we are maintaining a 2m distance or 1m where 2m is not viable, with personal protection equipment (PPE). The company has been split into department bubbles to protect staff and our customers
All staff are keeping a record of all contacts for track and trace to ensure maximum safety for friends, family and colleagues
Regular cleaning and disinfection of surfaces including all door handles, light switches, computer/telephone equipment, tables, chairs, kitchen & toilet facilities, air conditioning units etc
Reduced staffing levels and staggered working hours (extended over the weekend)
