I’m not sure if it’s common knowledge but Halfords do a trade card which I believe is extended to non trade engineers. I’m an aircraft engineer and got my card about 15 years ago by presenting my NVQ.

I bought the Bosch rear wiper and both front wipers for £30 2 weeks back.

I also previously have had new Yuasa and Bosch batteries replaced under warranty at Halfords with zero problems. The best thing is the staff are that poorly trained I always get another 5 year warranty when it clearly states the warranty period is from the initial purchase. 2019 5.0 SC SVA (Current)

That's true Brit Plumber, I didn't think I'd get one as I am a Mechanical Technician Offshore, so never bothered asking. Just asked one day on the offchance and the rest is history Wish i'd asked years ago now.
