Electrical Generator Systems in Warrington

McLennan Electrical Services can install, maintain, commission, service and repair a variety of generator and UPS (Uninterruptable Power Supplies) systems, including diesel power generator systems




Why should you invest in a generator installation?

For many industries or institutions, an electrical power failure can be catastrophic. Many could not function at all leading to financial loss and downtime, and in critical environments, such as hospitals, this could endanger life.

Most IT systems these days have battery back-up systems, which can support parts of the business for a short while, but what if it became days or even weeks, would your business have a contingency plan that is robust enough to cope with a prolonged outage ?

We have installed back-up generator systems in numerous different environments, offering the facility of instant automatic change over from mains to a generator, should the power fail.

Alternatively we can offer the manual change over, for businesses which do not have the option of having a full time back-up generator on site at all times, we can order a generator to hire for you and have you ready to ‘plug and play’ when it arrives.

We also install full construction site set up, from generator to mains, and 110v Distribution to remote areas prior to utilities connection.

Call us today for professional advice and a best fit solution to your needs.
