We don't charge emergency call out fees per se, but we do charge a rush fee if your problem can not wait til our next officially available slot. Rush Fees are allocated to compensate for: Dropping the project we're doing and getting ready to attend an unexpected booking, and then picking the project work we were meant to be doing out of normal working time.
The only real way of telling whether your electrics are completely safe is by having a thorough health check on the electrics (EICR) carried out by an experienced electrician. We specialise in these - please find out more here.
