In my opinion yes a halfords set is all you need for domestic car servicing etc but I have tried using them on choppers (farming kind not bike) and you soon see the quality's not as good as some cheaper sets. By cheaper sets I mean those bought from a reputable dealer the example I gave above SBS services are people that order parts for tractors, cars etc. so not everyone knows about them but there stuff is often better quality and cheaper in fact costco do a good quality set also. All I'm saying is you can get a similar if not better quality tool for cheaper from places other than halfords that's not to say there's are poor quality. In the end tho you can't beat the ol air wrench.
