London party wall surveyor FAQs
Do you provide party wall surveyor services across all London boroughs?+
Yes. Crown Party Wall Surveyors covers all 32 London boroughs across North, East, South, and West London. We are familiar with the property types, local authority requirements, and common party wall issues across the city.
When do I need a party wall surveyor in London?+
You need a party wall surveyor when you plan building work that affects a shared wall, boundary, or structure with a neighbouring property. This includes loft conversions, rear extensions, basement excavations, and any work within 3 or 6 metres of an adjoining owner's foundations.
How long does the party wall process take in London?+
The party wall notice period is a minimum of one month for building work notices (Section 2) and two months for new wall notices (Section 1). If a dispute arises, the surveyor appointment and award process typically takes 4-8 weeks depending on the complexity of the project.
Do I need a party wall notice for a London loft conversion?+
In most cases, yes. If your loft conversion involves cutting into or raising a party wall, inserting beams into a shared wall, or excavating within 3 metres of your neighbour's foundations, a party wall notice is required under the Party Wall etc. Act 1996.
How much does a party wall surveyor cost in London?+
Party wall surveyor fees in London depend on the scope of work, number of adjoining owners affected, and whether a dispute arises. We provide free initial consultations and transparent fee estimates before any commitment.
What is a schedule of condition and do I need one?+
A schedule of condition is a detailed photographic and written record of the adjoining property's condition before building work begins. It protects both parties by documenting the baseline state and is typically prepared as part of a party wall award.
Can you act as an agreed surveyor in London?+
Yes. Where both the building owner and adjoining owner agree, we can act as a single agreed surveyor. This is often faster and more cost-effective than each party appointing their own surveyor.
Do you cover outer London areas such as Bromley, Enfield, and Havering?+
Yes. We cover all outer London boroughs as well as inner London. Our surveyors travel across the full Greater London area to inspect properties and prepare party wall documentation.
What happens if my neighbour ignores a party wall notice?+
If your neighbour does not respond to a party wall notice within 14 days, a dispute is deemed to have arisen under the Act. At that point, each party appoints a surveyor (or an agreed surveyor is appointed) and the matter proceeds to a party wall award.
Do you work with London builders and contractors?+
Yes. We regularly work alongside London builders, developers, and main contractors to manage party wall compliance before and during construction projects. We provide all required documentation including notices, awards, and schedules of condition.
What London boroughs do you cover?+
We cover all 32 London boroughs plus the City of London. This includes all areas in North, East, South, and West London. See the region pages below for specific area coverage.
Can you help with a party wall dispute in London?+
Yes. We provide dispute resolution services under the Party Wall etc. Act 1996. Where a dispute has arisen, we can be appointed as surveyor to prepare a party wall award that resolves the matter without court proceedings.
