Thanks for all your help, so basically i can ask someone to install a DP isolator and a contactor between the power supply and my CU?
Answering your questions, the house is a private owned dwelling, F/A does have backup power, im not modifying the gas installation whatsover, the (battery powered) servomechanism is installed on the top of main valve and physically moves the handle. I dont think i need to submit a notification nor if it does need to comply with any rules but i will have a boiler replaced soon so i will consult with a gas safe engineer prior to installing it.
