I've heard that there are one stop shops in Bangkok that can issue visas for all three countries. Is this true? if so any details. I'm a UK citizen that will be overlanding Thai - Laos, flying into Hanoi and overlanding Nam to Cambodia.

Welcome to Travelfish C,
Most travel agents in Bangkok would be able to organise those visas for you -- though they'll be a service charge wrapped up in the fee of course.
Bear in mind that if you're overlanding from Thailand to Laos you can get a visa on arrival valid for 30 days, and the same goes for Vietnam to Cambodia (visa on arrival is again available at most crossings).
The only one you'll need in advance is the Vietnamese one, which can be easily organised in Vientiane.
