Both places happily accept contactless.
For the most part chip and sign is totally fine.
Contactless and ODA, however, break TfL, vending machines, self checkout, etc (self checkout needs PIN OR contactless).
Adding contactless with ODA would give near perfect UK acceptance even without PIN. Your preferred country may vary.
B&Q is a fairly big chain over there, I'd have to think at some point they'll fix that.
I'm curious, what is ODA? And does the lack of it still prevent using the ticket machine to top up Oyster cards or anything else, or does it just confuse the faregates only?
A workaround to this might be to register your Oyster online and link your credit card to that (I don't know for sure if you can do that or not though with a foreign card--been 13 years since I've been to the UK
