Planning controls can vary from one address to the next. Before relying on national Permitted Development guidance, confirm the responsible planning authority and check its current records for the exact address, including any conservation designation, Article 4 direction, listing or other site-specific constraint.
What is the Party Wall Act
The practical test for what is the party wall act is whether it reduces uncertainty before work begins. Good preparation creates a written scope, identifies the approvals or evidence to verify, and makes clear who is responsible for each step before walls, floors or shared services are opened up.
For this guide topic, the what is the party wall act stage should be judged against the property itself rather than a generic national checklist. In NW London, construction, access, leasehold terms, verified designations and previous work can change the appropriate route. Confirm those points before quotes are compared or materials are ordered.

How to serve a party wall notice
Trade coordination should make interfaces explicit: service routes, pressure or functional tests, substrate readiness, protection and final tolerances. Capture those decisions in the programme and written scope rather than relying on informal assumptions.
Sequence wet work, services, closing-up, joinery and finishes around the actual design and drying or inspection dependencies. Record who can authorise progression so one trade does not conceal work that still needs checking.

Good preparation creates a written scope, identifies the approvals or evidence to verify, and makes clear who is responsible for each step before walls, floors or shared services are opened up.
Costs and who pays
The balance between labour, materials, professional fees and logistics is project-specific. Ask each quote to separate those elements and identify allowances so comparisons are meaningful.
Accurate cost benchmarking requires comparing like-for-like quotes. Variation often reflects different assumptions about scope, specification and access rather than a directly comparable price. Ask contractors to detail exactly what is and is not included before comparing figures.
Party wall awards and what they cover
Before renovation begins, check whether the insurer needs notice of the scope, occupancy changes, structural work or contractor arrangements. If a reinstatement assessment is needed, use property-specific information rather than market value as a substitute.
Review the policy wording, declared construction, reinstatement basis, exclusions and notification duties against the actual property and proposed work. Ask the insurer or broker to confirm material points in writing rather than assuming that a general policy description covers the project.
