Party Wall Insulation

If a neighbour is undertaking works under the Party Wall Act, can you require improved sound insulation as part of the works?

Sound nuisance and improvement to insulation is often a matter raised to us when we are acting as an appointed surveyor for Adjoining Owners under the Party Wall Act.

Most often issues relating to sound or noise transference are raised to us by Adjoining Owners of residential properties.

In particularly in semi-detached and terraced properties or flats that are separated by a party wall or party structure and that which is suffering excessive noise transference.

The question that is often raised to us is :

‘Can we force the person/people doing the work, to install sound insulation to a problematic party wall?’.

It would be sensible to resolve any such issues while one of the neighbours are undertaking refurbishment or development works.

However, there is no mechanism in the Party Wall Act by which to force a developing neighbour to install sound insulation to a party wall or party structure under the Act.

Such improvements would need to be by separate agreement between the parties. This could be proposed if there is any requirement for access or other matters to be negotiated. But there is no obligation for a Building Owner to upgrade sound insulation to a party wall under the Act.
