Air Con

Ever since I got my 1.0 64 reg polo a few years ago i've never found the aircon that cold. I have to get it re-gassed every year it seems.
I run the AC during the winter, supposedly this keeps the seals lubed and keeps the gas in? Just tried it out last week when it got to 20C, looks like it doesn't work at all now, needs regassing probably.
Is the aircon notoriously bad on these models?

64 reg is the second half of 2014? After five and a half years, a regassing is to be expected. That's fine. This the the time that the a/c and battery might be going a bit bad.

yes 2nd half of 2014, how often are people regassing though? 3 times in 4 years?

I'd think that after 4 or 5 years, it would be beneficial to get the gas charge checked, or recovered, vac'd down and reloaded as per weight for this car.
Getting it regassed any more frequently that that does sound like there is a system leak somewhere.
I have to admit that my wife's August 2015 Polo 1.2TSI 110PS seems to have lost most of its gas, so it looks like while I did intend to monitor it's gassing level every year, I seem to have forgotten to do that as I was aiming to check its performance at the same ambient temperature each year - and the last two years did not seem to have high ambient temperatures when I planned to check it!!
That Polo hardly ever had its AC used, and that should not play any part in the lose of gas charge as these modern systems have variable displacement compressors that have a preset minimum displacement and no clutch, so they run at low displacement at all times even when the AC chiller is switch "off" and so all the system seals and all other plastic areas get a low volume of fridge gas and system oil mist passing over/through them always when the engine is running.
I'm hoping that my wife's car does not have an evaporator leak as that would not be a pleasant job to get in there and replace it, so as soon as things get back to normal, I should get that system recharged and keep an eye on it and check for leak sources.
