Also consider renting a shared accommodation during the week and going back home at the weekend. Perhaps buying a camper van is an option.
I can't imagine living like that.... is that a thing in the UK ?
Whether or not you are aware of it, its pretty much a thing everywhere. A lot of people work on short term things, and that's a problem, unless you have a large pool of potential clients within commuting distance. You either live in some form of mobile home, or have a permanent home and a lot of temporary weekday ones. I've known people who arranged their weeks as three 12 or 13 hour working days on site somewhere, then 4 days off back home, and did that for years. These days a more hybrid work from home some days, and work at a remote site on other days kind of scheme is probably getting more common. However, some of those people are doing things like installations, refits. trials, etc. where working from home is not an option.
