Why prices vary
The method drives the price: clearing a sink or toilet is cheapest, rodding a drain costs more, and high-pressure water jetting costs more again but clears compacted blockages. A CCTV survey (typically £150–£350) is worth it for recurring blockages because it finds the cause, such as roots, scale or a displaced joint, rather than treating the symptom.
