Party Wall: What It Is and How It Works

Understanding Party Walls with Hourican & Associates – Chartered Party Wall Surveyors in London

What Is a Party Wall?

A party wall is a wall that stands on the land of two or more owners and either:

  • Forms part of a building (e.g. the dividing wall between two terraced houses), or
  • Separates two buildings (e.g. flats, commercial units or townhouses), or
  • Sits on the boundary and is jointly owned (a party fence wall, not a timber fence)

In the UK, party walls are governed by the Party Wall etc. Act 1996, which ensures lawful notification and agreement between neighbours when building work may affect shared walls or structures.

How Does the Party Wall Process Work?

  1. Serving a Party Wall Notice: Required for works such as loft conversions, chimney removals, basement works, or excavation near a boundary.
  2. Neighbour Response: Consent, dissent with their own surveyor, or dissent with an agreed surveyor.
  3. Party Wall Award: A legally binding document issued if there is dissent.

Hourican & Associates Fees:

  • Party Wall Notice: £65 + VAT per neighbour
  • Schedule of Condition Survey: £585 + VAT
  • Full Award Service: £1,100–£1,500 + VAT

Why Are Party Wall Agreements Important?

Party Wall Agreements help to:

  • Prevent disputes through clear documentation
  • Protect both parties with a Schedule of Condition
  • Define access rights and responsibilities
  • Reduce legal risks if damage occurs
Hiring a party wall surveyor early reduces legal disputes by 80%

It has been a delight working with Richard. I had 5 party walls to sort involving a neighbour either side and owners of the flat above me. From start to finish it took approximately 3 weeks and was carried out and completed very efficiently. His response time was excellent and I would not hesitate to recommend his services. Jamie

Richard was absolutely brilliant in getting my party wall agreements for a complex loft extension across the line, throughout lockdown too, when getting access was challenging. He was very helpful when I then had to revert after a new obstacle arose, which needed his advice and a subsequent/additional award at short notice. Very much recommend - thanks Rich!

We engaged Richard Hourican for some party wall work and his response-time, ongoing communication, pricing and service were all excellent. He also went further and sorted us out with an engineer, who was also excellent. Highly recommended.

I engaged Hourican Associates for a Party Wall Agreement with 2 adjoining neighbours who are both tenants. Richard was very responsive from first contact and remained so throughout the consultation and when the Awards were issued. Very professional at all times and answered any questions in a timely manner. Our neighbours, both tenants and landlords didn't have any complaints either. I have recommended Hourican to some friends who may need similar services in the near future and wouldn't hesitate to use them again if needed.
