If you are doing electrician work then #1 priority is a voltage tester - something simple and reliable to do that one job that can save you skin.
If buying a multimeter then get one that is at least 300V CAT-III safety rated, otherwise you have a serious risk of it exploding in your face if you have an accident involving an energised system and a mistake in the use of ohms/amps instead of volts. You can get that for £80 or less. GS38 also reccomendes fused test probes, handy if you make the even-worse mistake of it being plugged in to a non-fused 10A range...
If you want to spend more then it is worth saving for a good MFT that can do high voltage insulation testing and medium current continuity testing. I have a 'simple' Megger that will do those bought for electronics work where I needed the HV resistance side, but for a little cost more just get a MFT in the first place! It will add the two other essential tests you will need as a sparky:
TL;DR don't buy a £10 multimeter.
