Look around for the Aneng AN8008

Dave did a review on the meter, I don't recall the outcome.
Ultimately, you will need 3 DMMs - watch some of w2aew's videos or Dave's. You will often see projects where 3 meters are used simultaneously. These tend to be the educational tutorials where they are trying to make a point. Two of the three can be less expensive and maybe, at some point, you buy a more expensive meter with better specs. Or not...
I use mine all the time in preference to the higher dollar meters.
If you don't trust the CAT rating, don't use the meter on mains during a lightning storm.

It looks like an AN 8008 to me! Sure, it will be fine for a first meter (I say glibly without checking specs or reviews)

So for the time being, might need to check the resistance, test a diode, continuity and maybe... maybe the capacitance? All low voltage stuff.
The budget is quite low - like 30-40 quid?

If the signal is time-varying, a scope is more appropriate than a DMM.
Either of these Siglents will do the job. The difference is bandwidth and inputs. We got by for a thousand years with 2 channel scopes but today we seem to think of 4 channels as the standard. I bought a 4 channel scope when I upgraded to a DSO - The Rigol DS1054Z which was the hot setup a few years back.
Today the Siglents are hot:
SDS1202X-E 2 channel 200 MHz $359

SDS1104X-E 4 channel 100 MHz $475
https://www.amazon.com/Siglent-SDS1104X-oscilloscope-channels-standard/dp/B0771N1ZF9
There are some epic threads about the Rigol over in Test Equipment. It is easily unlocked to provide 100 MHz bandwidth and the other options are now free from the factory.

(Sorry Dave, but we DO HAVE an eevblog multimeter in the house.)
I bought a slightly cheapo and rugged rubber encased multimeter, right here down the street, at:
O'R••••••s Auto Parts (in California).
PLUS, pay attention to some of their misc. LED and audio products. I picked up a 'cigarette lighter' receptacle add-on (under dashboard), where the thing has a USB Charging port. ow, with the (Auto Parts Store) Solar Trickle chargr I've got solar capacity to at least keep phone going, if disaster blackouts occur.
And the LED accessories are cool too.
I don't even drive, LOL.

Can anyone suggest any decent budget multi-meter (UK)?

Can't resist a punt here - this is well over your budget, and I don't know its availability - but if you're not going to get the dirt cheap DIY one I'd look at a Kewtech, in the technician range.
