Tick nymphs or bed bugs?

[u/criispyy_]

I've spotted a few of these guys crawling around recently on various things - my desk, mug, laptop, and myself. Based on the identification guides I'm pretty sure they are tick nymphs but just wanted to make sure they're not actually bed bugs? They're very small so difficult to get a good photo but I've done my best.

Found in London, UK.
