For me, finding tradespeople has been a problem since 2018, so it can't be COVID-related.
2018 and 2023 - tree surgeons - normally takes 3 or 4 different ones before I find one that doesn't ghost me.
2019 - landscaper (to build concrete foundation for a shed) - job was probably too small. 1st builder ghosted me and the 2nd one did respond but the response was 6 weeks after my query and I had already had a 3rd person complete it for me by then. So too little too late for the 2nd guy.
2022 - kitchen replacement - found a joiner in 2021 ok but the booking/start date got delayed twice due to a supply chain issue from the supplier (B&Q). Finally got given a definite date in early 2022. Once started, it all finished ok, albeit the project over-ran by 2 days.
2022 - electrician - the one that did work for me in 2015 did respond to me last year, but then I had to move the date because I had 4 eye operations. Then once I was ready and called for a new date, he ghosted me, so my electric work is still outstanding in 2023 as no one else has responded.
2022 - decorator - to sand down and re-paint my entire downstairs, so probably a big enough job for someone over a few days. 2 decorators ghosted me, and the 3rd one keeps pushing the date back and it's now 15 months that I've needed this paint job.
One problem I don't have is with plumbers. I have a local plumbing firm in Stafford called AR Plumbing & Gas and they've always been responsive and done work for me over the past 5 years. Boiler service can be booked a few days in advance and a new boiler that I needed last year was booked 2 weeks ahead. All radiators replaced recently + Google Nest system and new shower fitted.
Home insurance (Santander) is the other area I've not had a problem with. There was loft damage last year where water had come through the roof, through my loft, into my bedroom, wrecking the loft boards, bedroom wooden floor tiles, bedroom ceiling partially caved in and a bit more water leaking to downstairs in the kitchen. Needed bookings with a few different firms to assess the damage, test for asbestos, get some quotes, order supplies, pay £350 excess, then finally get the different tradespeople booked in, a timely schedule printed on A4 paper. Also, they did more than just the repairs as a bedroom re-paint was also in my claim which I didn't expect or ask for, so that was the kicker for me
I was able to choose the paint colour and the new wooden flooring tile design. I now need my downstairs re-painted lol
