When a drain blocks, the first question is often who should deal with it. The answer depends on the location and whether the drain serves one property or more than one.
The most useful first step is to look at the pattern: what is affected, when it happens, whether the issue is inside or outside, and whether it has happened before.
Quick checks
Use these quick checks to understand the issue:
- Drain only serves your property: usually private responsibility
- Shared drain serving multiple homes: may be shared or public
- Lateral drain beyond property boundary: often water company responsibility
- Road drains and highway gullies: usually council responsibility
- Unknown route: inspection may help clarify the next step
What the symptoms can tell you
Private drains explained
A private drain usually serves one property. If the blockage is within the private section, the property owner is usually responsible.
Shared sewers and lateral drains
If a drain serves more than one property or sits beyond the boundary, a water company may be responsible in many situations.
Highway drains and gullies
Road gullies and highway drainage points are usually separate from private property drainage.
When further investigation or help may be needed
Drainage support or CCTV investigation may be useful when symptoms keep returning or the cause is unclear.
- Water is backing up or overflowing
- More than one fixture is affected
- Bad smells or gurgling are present
- The same issue keeps returning
- An outside drain is involved
- The cause is unclear

Common causes and practical indicators
Gradual build-up
Grease, silt, scale, wipes or everyday debris can reduce flow over time.
Local restriction
One affected fixture can point to a blockage close to that outlet.
Wider blockage
Several affected fixtures can suggest a restriction further along the run.
Root or pipe damage
Recurring symptoms may need CCTV investigation to understand the cause.
Shared drainage
Neighbouring properties or shared chambers can change the likely next step.
