At Salisbury Drains24, we’re often asked, “Can I repair or reline this drain myself?” The answer depends on several legal factors. Whether you’re a homeowner in a semi-detached house or managing a block of flats, it’s essential to know your legal responsibilities before any work is done.
Below, we break down the UK drainage laws relevant to residential and multi-occupancy properties, focusing on shared systems, access rights, and legality of drain relining.
🏘️ Private vs Shared Drainage Responsibility
- If the pipe serves only your home, it’s your responsibility to maintain or repair it.
- If the pipe serves multiple homes or flats, it may be a shared drain, which involves:
- Joint responsibility inside the boundary (e.g. between leaseholders or the freeholder).
- Water company responsibility once outside the boundary (e.g. Wessex Water).
⚠️ You cannot legally reline or alter a shared drain without consent.
📜 Drain Relining in Multi-Occupancy Properties
Modern relining techniques like CIPP lining offer non-invasive solutions for drain repairs. However, in multi-occupancy properties, relining becomes a legal issue if the pipework is shared:
- Consent Required: You must get written agreement from all affected leaseholders or the management company.
- Building Regulations Part H: These apply to all drainage works — ensure your repair method complies.
- Party Wall Act 1996: If the drainage runs beneath shared or adjoining walls, formal notice may be required.
- Access Rights: Carrying out works in shared communal areas or under other units requires proper notification and approvals.
🚫 Unauthorised relining could breach lease terms and even void insurance policies.

In historic towns like Salisbury, older properties and terraced homes often share lateral drains. If you live in areas such as Wilton, Laverstock, Amesbury, or Downton, there’s a high chance your pipework may intersect with neighbours’ systems. Don’t risk legal trouble—get it assessed properly.
