Unbelievably bad.when I arrived a couple were having an argument with the LAD behind the counter ( not a good start )Our Car wouldn't start so spark plugs replaced.still wouldn't start .suspected fuel contaminated? ,daughter adamant right fuel was put in ,Halford staff confident it would rectify the problem so fuel system was cleaned total price £360.collected the car it wouldn't START !.Then told no petrol in it .Petrol put in still wouldn't start.Demanded a refund .Two other customers in the garage at the same time as us both complaining about the staff "not having a clue". Car transported to different garage diagnosed a faulty coil , replaced car now back on the road . Don't even consider taking a car there , unless it's to have air IN THE TYERS .
