Change Logo / Rebrand for electrician

I currently am trading as Nest in Essex Electrical Services, and would like to change my company name to Spike Electrical Services and as such need a new logo designed.

My current logo is as below, I would like to keep the cables around the outside, and change the centre part from nest in essex to spike electrical services with a new drawn logo.

My thoughts are using a graphic of an electric spike perhaps used as part of someone hair, or integrating one of the attached image - I open to ideas.
