E&M Security acts as primary key holders for your property. This means that we respond to any security alarm activations, eliminating any risk to your employees. In the event of alarm activation, a security officer attends your business to carry out a full external and internal patrol. By doing this, we’re able to ascertain the cause of the alarm activation and then carry out the set procedure. There’s no-one better than us when it comes to key holding, so call us today, in Colchester, Essex.
