Best broker to use for XAUUSD in the UK with 20K capital?

I’ve been using a plus P500 demo account for a few years now working on a system. Finally feel I’m ready to start using my own capital. Only problem is I’m not sure if I want to use P500 as my broker, as I’m not sure who truly has the best XAUUSD client base.

Ideally looking for the most liquid XAUUSD broker in the UK, With a large variety of unit sizes. Low overnight funding (and general) fees would be great. Whilst also being able to Hold Buy & sells at the same time on 1 instrument. 20K starting capital if that helps with anything.

Many thanks for reading,

RB
