Highly professional, deeply knowledgable

One Zero installed an additional solar battery to my system and set up the emergency power supply so that we continue to get an electricity supply to the most critical circuits in the event of a grid outage. The work was performed to an exceptional standard, including fireboarding the space, adding a connected smoke alarm and a thermostatic extractor fan. Great comopany and will definitely use them again if I ever want to further upgrade my system.

EXCELLENT COMPANY

Could not have done more to explain everything before hand and after the Solar Panels were installed.
Answered any questions I had , or pointed me in the right direction if they couldn’t answer it themselves
Would definitely recommend this company to anyone.
One of the best investments I have ever done.
Thank you
