A blockage is a symptom with many possible causes. Soft blockages (paper, wipes, food waste, grease) can usually be cleared and stay clear if habits change. Structural blockages (roots, collapses, bellies) will keep returning until the pipe itself is repaired.
The pattern matters: a first-time blockage after heavy use is very different from a drain that blocks every few months at the same place — the latter almost always has a structural cause worth confirming on camera.

Anywhere in the system, most often at traps, junctions, bends and root-affected joints.
A CCTV drain inspection is the standard way to confirm whether this is what's happening in your pipes: the camera shows the condition on screen, a locator pinpoints the exact position and depth, and you get a recorded report before any repair decisions are made.
A CCTV drain inspection shows exactly what's happening inside your pipes — no guesswork.
