I know four people that do home improvements, building work, 3 of them to high standard, one is a jobber, conscientious but self taught. From simple decorating to high end kitchen/bathroom installations, they're very busy and always turning down work.
Everywhere is facing labour shortages, everywhere. We see more and more Polish who came in the 90s headed home now to retire, earned their money, built their houses back home or just want to be back with family.
We hear Romanians are headed to Italy, nearer home, many speak Italian and apparently the benefits are better there.
Covid has seen a lot of people go back home, we lost a good few for that reason, Brexit will have had an impact but we didn't see a mass exodus. (bearing in mind we have up to 1000 agency workers here a day, most being E European)
I suspect Brexit spooked some, then Covid was the icing on the cake that made their mind up.
I used to do small jobs for pay years ago, simple DIY, decorating, shed felting etc, you always had people that wanted stuff done and were happy to pay but it spoiled me when I thought...what if something goes wrong, you dont get paid or worse, get sued. I stopped shortly after. Theres a lot of responsibility doing that kind of work.
