BURG-WACHTER 272S Sold Secure Gold Aproved D Lock Bike Lock £13.99 @ Amazon

Just be aware of the very poor durability & locking up issues that happens with a few uses or within a few months amazon.co.uk/gp/…r=1
An example: "In 𝗼𝘃𝗲𝗿 𝗵𝗮𝗹𝗳 𝗮 𝗰𝗲𝗻𝘁𝘂𝗿𝘆 [50 years] I have never seen such a poor quality lock. It is the first to ever fail in all that time. I have used it four times and it has never been outside of my house so never been wet or dirty yet it has jammed so I cannot remove it. Neither key works."
If you do go for it, treat it with kids gloves & oil it frequently. If left outside in the rain, I'd also cover it with a strong plastic bag. (edited)

I've had and used one of these locks regulary since November 2021. I have oiled the lock regulary and its still going fine. I do use this with another different u lock and a bicycle chain. I don't expect the lock to prevent but maybe / hopefully deter theives from taking my bike and choose something thats less hastle to get unlocked.
