The D&N Maintenance commercial electricians are fully qualified to repair any electrical problems a business may be experiencing. Often retail and hospital premises have long cable runs, which could be better secured. Others use generators as backup units to keep the business running, which need a specialist to install. Complex commercial electrical systems often require a fast diagnosis when there is a fault, to make sure that day to day operations are not impacted. We specialise in finding these problems and fixing them with as little disruption to the daily activities as possible.

We understand that a power disruption or other electrical fault can be very costly for any business, which is why we offer emergency repairs.
