Common Questions
How quickly can you get to me?
We aim to arrive within 60 minutes for emergencies across Cardiff. Response times may vary slightly for outlying areas, but we'll always give you an honest ETA when you call.
My power keeps tripping - is that an emergency?
It can be. A repeatedly tripping circuit breaker could indicate a serious fault. Turn off the affected circuit and call us - we'll assess it over the phone and advise.
Do you charge extra at weekends or evenings?
Our emergency rate is the same whether it's 3pm or 3am. No hidden surcharges.
