Removing a Chimney Crawley & Party Wall Agreements

Do You Need a Party Wall Agreement to Remove a chimney Crawley?

In most cases, yes — you will need a party wall agreement to remove a chimney, particularly in terraced or semi-detached homes.

Chimneys are usually built into a shared (party) wall, and removing them involves structural work covered by the Party Wall etc. Act 1996.

Is a Party Wall Agreement Required when removing a chimney Crawley?

You are likely to need a party wall agreement if your project includes:

  • Removing a chimney attached to a shared wall
  • Cutting into the party wall
  • Installing steel beams or structural supports
  • Supporting or altering the remaining chimney stack
  • Making structural changes to a shared wall

These works are considered notifiable under the Act, meaning you must inform your neighbour before starting.

When Is It NOT Required?

You typically won’t need a party wall agreement if:

  • Your property is detached
  • The chimney is not connected to a shared wall

However, this is uncommon — most chimney breasts in UK homes form part of a party wall.

Almost always yes

A party wall agreement (formally called a Party Wall Award) is a legal document that:

  • Sets out how the work will be carried out
  • Protects both you and your neighbour
  • Prevents disputes during construction

It is prepared by a surveyor (or surveyors if both parties appoint one).
