Best recommendation for a UK Broker for intra day and options trading

Hi everyone I'm new to trading and have been researching strategies for a few months now. Could anyone recommend me a reputable broker in the UK for day trading and options that won't scam me? Preferably with hot keys options.I'd also like to know if its possible to trade with an American based platform in the UK?
Thank you for your time!
