There are a variety of drain types currently in use in the UK. The most common is the communal drain, where a common drain in the road connects to each property individually. This is the easiest to clear, as each house only has one connection to the drain.
Some houses have a drain that runs under a row of houses, with a manhole cover placed at strategic points. This is problematic, as the blockage could come from either end of a house with a blockage, and permission must be obtained from the relevant occupiers to jet their manhole cover.
The least common option is the septic tank, most commonly employed in rural areas that do not have a mains drainage system. If you need to know how your drain is arranged, your sewage provider will be able to provide you with a map.
