I’d like to thank both Pete and Lucky Les for their advice. Our electricity does exactly the same during the winter and it would drive you crazy. Left in darkness in shower one night! Wall heater was on, air con in the bedroom, various other devices and wham! Pitch black and no torch! It is awful really. Why in heaven’s name would any house have a power supply that only allows you to use 3kws?
I would also like to upgrade our supply. Do I go to an Iberdrola office armed with a utility bill? Should I also bring my passport with me? Could this all be sorted out while we are visiting for 2 weeks? Many thanks for your wonderful advice
