Apart from the Pi4, to upgrade, I know that I will need a bigger power

I get away with the Pi4 without any additional cooling, or do I need a
heat sink or fan, and if so, how do they get on with the hat ?  The
space it is in has had a temperature range of -1 to 40 degrees C, the

 Adrian,
 No problem with the other suggestions.
 When you say "starting to struggle" what have you measured?  Are you running out of memory, CPU power, disk I/O, or network I/O?  I think it would be useful to know what exactly in your system needs changing.
 It's possible that a Pi 3B+ might be a sufficient upgrade (but can you still get them?).
 

Can in uk at the moment. all sorts.

The Pi-5 creates quite a bit more heat than the Pi 4, and has some software compatibility issues, so unless you really need the 5, stick to the 4.  (I have both here).

I think that's a good point
  If you are not running headless, the Pi 400

has a heatsink and keyboard built in.  I have a couple here and have been very pleased with them. One even runs both Windows and Linux, that's using the Twister OS.  It uses about 2 GB of its 4 GB memory, and averages 10-12% CPU.

If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the political, economic and/or military consequences of the lie. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State.
