Six simple steps from notice to completion

Adjoining owner has 14 days to consent or dissent. If they dissent, surveyors must be appointed under the Act.
Each party appoints a surveyor, or both agree on a single agreed surveyor to act impartially for all parties.
Party wall surveyor prepares photographic record of adjoining property's condition before proposed work begins.
Surveyors prepare award detailing how works will proceed, working hours, and measures to prevent damage to party structures.
Building work can begin once award is served. Final inspection confirms no damage occurred or arranges repairs if needed.

A party wall agreement, properly called a party wall award, is a legal document prepared by appointed surveyors under the Party Wall etc. Act 1996. It sets out how building work affecting a shared wall or boundary will proceed, what protective measures are needed, and how any disputes will be resolved. The award protects both the building owner undertaking works and the adjoining owner's property.
Yes, most loft conversions in London require a party wall notice because they involve work to a party wall. This includes raising the height of a party wall, cutting into the wall to insert steel beams, or removing a chimney breast attached to the shared structure. You must serve notice at least 2 months before work starts, even if your neighbour agrees to the proposed work. Learn more about loft conversion party wall requirements.
Party wall surveyor fees vary depending on the complexity of works. Simple rear extensions typically cost £500-£1,500 per surveyor, while complex basement extensions may cost £2,000-£5,000. The building owner usually pays for both their own surveyor and the adjoining owner's surveyor. An agreed surveyor acting for both parties can be more cost-effective. See our complete cost breakdown.
If your neighbour doesn't respond within 14 days of receiving the party wall notice, they are deemed to have dissented under the Act. This means surveyors must be appointed to resolve the dispute. Your neighbour will need to appoint their own surveyor, or you can appoint one on their behalf if they fail to do so.
Yes, the Party Wall Act applies to basement extensions in two scenarios: if you're excavating within 3 metres of your neighbour's building and going deeper than their foundations (Section 6 of the Act), or if you're underpinning or working on an existing party wall. Most basement conversions in London trigger party wall requirements due to the proximity of adjoining properties. Read our basement extension guide.
No, you must not start work covered by the Party Wall Act until the statutory notice period has passed and the party wall award has been served. Starting work without following the proper procedure is unlawful and could result in an injunction stopping your building work and potential legal costs.
Party Wall Agreement London covers all London boroughs including Central London, North London, South London, East London, and West London. Our party wall surveyors serve areas from Westminster to Wandsworth, Hackney to Hammersmith, and everywhere in between. We're experienced with all property types from Victorian terraces to modern developments.
A schedule of condition is a photographic survey documenting your neighbour's property before building work begins. It provides evidence of the property's pre-existing condition, protecting both parties if damage claims arise during or after construction. For high-risk works like basement extensions or excavation work, a detailed schedule of condition is essential. Learn more about schedules of condition.
