Well, depending on how much flying you want to do, you really should look at joining a syndicate if you can. Anything over 25 hours per annum on an SEP merits it, plus you'll get the chance to develop your skills potentially with other group members.
However, it's worth noting that a lot of groups require a minimum of 100 hrs, therefore you'll maybe have to pay twice as much for the moment by renting...
So, you need to do some research on what's available and how easy it is to book, and on that business of remaining current, different clubs have different rules (some imposed by insurance restrictions, some by club policy).
Or you could see if anyone's renting out privately... So it's down to you to an extent, you'll have to mooch around, pick up on what's going on at the local airfields (plus of course some kind soul here on pprune or maybe on
www.flyer.co.uk forum - which has a section on group flying - will chip in withj some useful info).
Good Luck !
