Party wall surveyors in london

As renowned Party Wall specialists, we have been trusted for over 20 years to deliver projects and protect people’s homes.



The Party Wall etc. Act 1996 covers three distinct types of work; alterations to party structures (usually walls but may also be floors), the construction of new walls at the boundary and excavation close to neighbouring properties.

These are some typical examples of work that is likely to be covered by the Act:

  • Cutting beams in to a party wall as part of a loft conversion
  • Removing chimney breasts that are attached to a party wall
  • Excavating for the foundations to a new extension within 3m of a neighbouring or shared structure
  • Underpinning a party wall to facilitate a basement extension

Where work falls within the scope of the Act it is necessary for a building owner to serve notice and obtain the affected adjoining owner’s consent; if that consent is not forthcoming the parties are deemed to be ‘in dispute’ under the Act and surveyors must be appointed so that the dispute can be resolved by way of a Party Wall Agreement (technically called an ‘Award’).

If the two appointed surveyors fail to agree upon any of the issues in dispute they can make a referral to a previously selected Third Surveyor.

At Peter Barry we have a 12 strong team of experienced party wall surveyors, assistant surveyors and specialist party wall administrators to help ensure that everything runs smoothly.

We cover the whole of the inner M25 area from our network of London offices so if you are planning on undertaking work that falls within the scope of the Act or have received a notice informing you of proposed works that may affect your property you are very welcome to contact us for some advice.
