Electrical Additions & Alterations


It is common for most electrical installations to need some form of addition or alteration during their lifespan. We can help with any type of domestic electrical installation, addition or alteration, from minor works such as adding a new socket outlet, though to more major works such as the addition of a new electrical circuit to better serve your needs.

Our experienced, certified electricians are available to carry out all types of electrical installation in Wirral, Liverpool, Cheshire, North Wales and North West regions.

Electrical Installation Certification


An electrical installation refers to the ‘fixed’ parts of an electrical circuit such as the wiring, wall sockets, consumer unit (fuse boards) and distribution boards. Electrical installations can be added to or altered as user requirements change but any work should be done by a qualified electrician as certification is often required.

The type of certificate will depend on the extent of the work being carried out – generally a Minor Electrical Installation Works Certificate for small scale alterations or an Electrical Installation Certificate for larger electrical additions, but your electrician will be able to advise and provide this after completing the work.
