Are you set on a magazine fed rifle? Maybe so because of your 'pest control' note. At this point I am going to put in a plug for the AA S400. Many moons ago when looking for a 'first PCP' I looked at a lot of rifles. I almost decided on a S200 but wondered about it because I found the action felt just a little bit small and fiddly to me. The S400 on the other hand was fine, plenty of space for loading and a very simple, reliable action and accurate too. Shot count was good as well; plenty enough for an HFT course plus some 'zero checking' beforehand and without a regulator. Also, being single shot, it fitted HFT perfectly. If you use a magazine fed rifle you need to remove the magazine between target pegs, which can be a bind. OK, you can get single shot units for some magazine fed rifles, but not all, so you may be happy with that. I bought my S400 s/h and got an extremely good rifle, scope and bag as the deal.
At the risk of being a kill joy I am going to suggest that with a PCP you would really be better off with your own charging equipment .. bottle or pump. Being reliant on your club sounds fine but, to me, is a bit risky. Many HFT clubs offer a fill service for a small fee but even they have been known to suddenly have an 'empty' bottle or a fill adaptor gone missing.
At even more risk, I will comment on scopes. Many people will tell you to allow for maybe 40% of the rifle cost to spend on a scope ... or is it a higher %? I do not believe this is necessary these days and there are some excellent scopes at the cheaper end of the spectrum. Now I am not saying very expensive scopes (£300+) are not worth the money, just that a cheaper one at maybe £100 can be just as good. Try and see ... look for a reticle you can see. Sounds obvious but I find some so thin they are difficult to make out against some backgrounds.
But whatever ... try and have fun selecting your equipment.
Cheers, Phil
