Corporate Event Planners

I was wondering if I could possibly ask for some advice on behalf of my son? He is in search of a reputable corporate events planner based in the south-east/London for a series of upcoming events - he has been recommended the following company due to positive word-of-mouth reviews https://www.letticeparty.com/events/corporate-events/ and I was keen to get any insight from others.

Thank you for your time.
