We fit awful
I had Halfords fit 2 headlight bulbs in my KA and Friday it went to a proper garage and failed the MOT due to the 2 headlight bulbs one of which "had not been fitted properly".
They say they have competent staff however this has failed to be seen. I will never be allowing any member of halfords to touch my car ever again. Their staff are clearly incompetent.
I would urge everyone to avoid the we fit service like the plague and just pay a proper garage to fit items for you. Okay its more expensive but at least it will be done properly.
