Looking for Recommendations on Tour Agencies for Expat Travel in London

I’m planning a trip to London and feeling a bit overwhelmed by the number of historical sites to explore. I love optimizing my travel routes and navigating local transit, but I’m curious whether a tour agency could make my experience even better. Are there any agencies out there that specialize in expat travel and offer insights or routes that stray from the typical tourist trails?

I’ve had decent success planning trips before, especially to France, but I think London might be a different beast. There’s so much history and so many neighborhoods to cover, and I really want to make the most of my visit. Has anyone used a tour agency in London that enhanced their experience? What should I look for when selecting a good one?

I used a local agency called “Secret London Tours” last year, and it was pretty great. They focus on the hidden gems and off-the-beaten-path spots instead of the regular tourist traps. Also, definitely check their reviews to see what past travelers thought—it can help narrow things down!
