Hetty, don't you realise that the plumber carries his tools in his vehicle? Do you expect him to waste a large chunk of his day walking from one job to another? Yours would probably be one of many jobs in a day. For goodness sake be realistic.
Sorry to sound harsh but small self-employed tradesmen have a difficult enough time. Likewise, the people who say "while you are here, could you just do ......" Those extra jobs have to be paid for at the going rate. These men have families to keep, business expenses to pay including very expensive insurance before they even start working, vehicles to buy, run and repair, merchants to pay and frankly £25.00 per hour would be ludicrously unrealistic to charge. They also have to keep their skills upgraded and have to pay for the courses to do that and then pay for the certificates they gain at the end of the course. £45.00 per hour would be a more realistic amount to pay and frankly that would be a bargain. They don't get to keep the £45.00 either, their is tax and National Insurance and advertising, membership fees for professional membership of the trade organisations. These are just some of the expenses incurred, there is no holiday pay or sickness benefit for the majority of them. I am not having a go at you personally , please understand that, I am just frustrated at the thoughtless comments and implication that hard-working tradesmen are dishonest. They are people's husbands, partners, fathers,sons, brothers just trying to make an honest living.
