I think it depends on the Halfords. I would take much notice of reviews that cover the entire country. Just because one Halfords is bad, doesn't mean another one is the same.
I used to use the one in Acton which was excellent, but closed down as they sold the site. The manager moved to the Halfords in Hanwell, previously Iversons, and I now go there. He's excellent and runs a really good shop. I've compared their prices with local garages and they're comparable if not cheaper.
Another benefit of Halfords is that you can do pay later for those who can't afford to pay upfront. They do very good 0% monthly payment schemes. Also they have a motoring club which gives discounts on services and purchases.
That said, I haven't been to the Chiswick one, but would definitely recommend the Hanwell branch.
