Questions
Frequently asked
Do I need a new board or a full rewire?
Sometimes only the board. Sometimes the wiring fails testing too. Survey tells you which.
What about surge protection?
Often recommended on new boards. We'll spec it in the quote.
Three-phase?
Ask us at survey stage — we'll explain the DNO vs on-site split clearly if it applies to your job.
Will power be off?
Yes for a period. We plan timing with you (and trading hours for commercial).
Is a CU swap a big job?
Usually not alone. This page still matters because it feeds rewires, extensions, and commercial capacity jobs.
