A power network failure will harm your business. It is well-documented that small and medium sized enterprises (SME) are especially vulnerable. Short term losses are bad enough but the knock-on effect can lead to continued losses in the long term. Even very small businesses with fewer than 10 employees can lose hundreds of pounds per hour when the power is down.

You can do very little if the national or local UK power grid is down. UK power companies are fully aware of the impact of a mains failure on local businesses and public services and work hard to restore the power as quickly as they can. If your switch gear or sub-mains that has let you down, you need to call 07956 523316 fast.

Problems of Mains Electricity Outages

Whether you are in Croydon, Lewisham, Southwark, Greenwich or wherever, the issues facing you when your mains electricity is off are many. The obvious one is a loss of productivity, however, a failed mains or sub-mains system can go a lot further than that.

Health and Safety

Firstly, there are H&S considerations. Heating, ventilation and air conditioning systems will be down, as will the lights. Somehow, You will need to find alternative heating, lighting or perhaps even cooling to maintain suitable working conditions. You may need to close down completely until the problem is resolved and the electricity supply has been restored.

Data Loss

The effects of a power cut on a computer system can range from mild to catastrophic. The worst case is that it destroys and corrupts your system hard drives. This necessitates major input from IT specialists to recover part or hopefully all of the data. On the other hand, you may escape with only a little data being lost, which may be recoverable when power is restored.

Security and Access

Security conscious Lewisham, Southwark and Greenwich businesses often fit advanced electronic systems to control and monitor access. This is very much the case with public buildings. But what happens when the mains or sub-mains circuits fail? A decent system will have back up in place, but essentially, security will be less effective. For businesses and public buildings where security is paramount, call us on 07956 523316 at any time – we are qualified and experienced in the fitting of back-up power supplies (uninterruptable power supplies or UPS for short).

Resilient Sub Mains and UPS

Given the potential problems with a failed sub-mains system, it is well worth the time and effort of looking at back up power systems (UPS). That is particularly important where any data loss or a security outage could be potentially disastrous. It is also crucial that you have a robust sub mains distribution system. These are based on distribution boards, commonly referred to as Ryefield boards.

But you need to bear in mind that for many electricians, fitting and repairing Ryefield or other brands of distribution boards is not a regular job. Nor are they used to the different methods of setting up a sub mains system. It needs a qualified and experienced electrician who is familiar with the requirements of correctly splitting and balancing the incoming supply. Almost any electrician could look at the specs of a Ryefield board and figure out its basic principles, however, there is much more to installing one than that.
