Doorbell just rang, someone asking to read the electricity meter. We are on the top floor and have a video entry system so I could see what he looked like. I am sure we've just had it read in the last month or so (6 weeks max) so I said 'i'm sure we've just had it done', to which he replied 'oh there's been a problem with the reading we just need to double check it's right'. Anyway I said 'it's not a good time can it be done at a later date', to which he replied ok and went off. Think I'll call the electricity board to check - was a bit strange as he had big comedy glasses on (they may well have been real, in which case he should have gone to specsavers ) and a woolly hat - and it's a lovely sunny day today....
