As many have already said, nothing replaces first hand experience: touching, using, feeling. I'm sure many here have been disappointed by binoculars that receive a lot of praise and/or have experienced an unexpected surprise when using some "unsung hero".
On the other hand, you don't mention any detail that can be crucial when trying to give you any advice at all.
- Format: magnification, lens diameter, weight
- Intended use (weather, holiday day, serious birding dawn/dusk, long range/coast, forest, etc.)
- Whether you use glasses or are old/young (these details can steer your choice in one direction or away from some choices)
Having said that, an advice I wish I had been given a while back is: don't underestimate second hand. Since you live in the UK, which is a DPAB (Densely Populated Area of Birders
) I'm sure you can find great deals on second hand binoculars, where 250 GBP can be stretched to amazing lengths (the Classified subforum here on Birdforum is usually a good proof of that). You are not unlikely to find a pretty good example of a middle-class device from a previous generation still in great shape.
Then, big brands that produce reasonable quality at lowish prices (such as Nikon Monarch 5) are usually a safe bet, or else some "enfants terribles" like the Vanguard Endeavor and the like.
Hope this helps
