The PM gets £30,000 a year to run their official residence which is the private residence at number 10/11. I think they also get a huge amount to refurbish to their own taste. They all spend it, of course they do. Whilst most, if not all of us, couldn’t afford those prices, rich people can and do pay them. Every PM refurbishes to their own taste. It sounds wasteful, it is wasteful, but it’s the rules. PMs and MofP look after their own interests. Look at the way we pay for all their second homes in London. They don’t give them back when they lose their seats or resign. Of course they don’t, it’s all set up to benefit them. ‘Twas ever thus.
