you need to screw in the stop screw.

As above, adjust your limit screw. There are several good video guides for this on youtube.
At first I didn't think it could be that, because it wasn't constant, but then I noticed that I could pull the shift lever when it was already on its lowest gear and it would move further left before returning back to its position. Clearly when I shifted down, the derailleur moved to hit the spokes before springing back onto the largest sprocket. So turning the stop screw solved the issue.
I wish I hadn't decided to do the adjustment whilst I was halfway home though, because now my hands are absolutely freezing. Really appreciated the quick replies, considering my terrible choice of places to work on my bike.

Go on YouTube and search 'gear adjustment'
You want the video that's 7:25 long by leonardmlee from 7 years ago.
I have the shortcut saved on my PC, but I'm on my tablet and can't see to be able to link it for some reason
Anyhoo, that's the only gear vid you'll ever need

Check that none of the spokes are damaged. I had a rear spoke break some time after being scraped by a close encounter of the rear mech kind. It was on a forum ride to Blackpool and I had to come back on the train because my low spoke count wheel could not be straightened enough to be trusted to last the ride home.
Thanks smokeysmoo, added that vid to my favourites for the future.
I checked it. Fortunately the mech wasn't getting fully embedded or anything, it was just lightly tapping the spokes - and I guess it was. None of them are broken, and it's all still true.
None of them seem damaged either, though with that said I don't know what to look for. I only tend to use the larger sprocket at low speed anyway, so hopefully this won't be an 'unpleasant surprise' - especially considering I've got a low spoke-count wheel too.

The wheel had been damaged by a friend. A couple of spokes broke at the time and he replaced them before selling me the wheels. What neither of us noticed was that one of the remaining spokes had been 'nicked'. It lasted a few rides before snapping.
The wheel wobbled so badly that I had to remove my rear mudguard and brake blocks in order to ride to Blackpool station. I kept my speed down and cornered very carefully in case the wheel collapsed completely!
I have got away with riding a 32-spoke wheel reduced to 31 by a breakage, but a 24-spoke wheel reduced to 23 did not seem a good bet.

If after doing a thorough job on adjusting the screws on your gears and checking your spokes (as Colin has suggested), if you still can't get the gears right, I would suggest your derraileur hanger is out of alignment. You could either take your bike to a shop for this fix or purchase one of these.

I had this same problem on my road bike. When the gears were changing ok, my chain was rubbing spokes when in the largest cassette cog.

If the derailleur has only just started contacting the spokes, you ought to ask yourself why.
It's very seldom wear in the derailleur pivots - they will carry on working for years before that becomes significant. Check that the main mounting bolt, hidden inside the swivel, is tight as they can work loose.
