Obviously the big stores accept them, Selfridges(nationwide), Harrods, Harvey Nic's etc, but there are a lot of smaller retaiers who accept them(particularly the more expensive they are).
Not just in London either, in Bournemouth they ran a campaign to get retailers to accept euros and 50 retailers signed up...

That article is almost 6 years old also, how many still do now?
You say yourself you stopped doing it due to fraud, which is one problem - the other being changing exchange rate. Large tourist shops like Selfridges and Harrods have a bureau de change in them, as do most larger M and S stores (who are also a bank) - so no problem exchanging the cash or getting the current rate. I don't know of any other places though.
I hope we sign someone soon so I can go back to not posting and just lurking.
