for home mechanics:
metric allen key set, cost about a tenner for some decent ones.
15mm spanner, a couple of quid from a diy shop
track pump, try not to get the very cheapest one, but I got one for a tenner in a sale and it's bad b but does the job.
Chain whip, you don't have to spend a lot, they're all the same unless you get a really expensive one.
Lockring tool, it's included in some chain whips, so get one of them.
Chain tool, you can get a half decent one for a fiver.
Cable cutters, fairly expensive but you can just buy some when you need them.
On the go mechanics:
Small travel pump, they're all shit, it just needs to get some air in the tyre so you can get home.
Tyre levers, get Pedros, they're the best.
15mm spanner, you should already have this.
Spare inner tubes, carry at least 1 with you on all journeys. You can often get deals like 10 for £20 online, chain reaction cycles have been doing this recently.
You can just buy the tools as you need them, but being prepared will save you money and time having to take your bike to a shop to get fixed especially if you get a puncture on the way somewhere.
