Quick answer: Consent may be reasonable where the notice is valid, the drawings are clear, risks are modest and suitable safeguards are recorded. Do not consent merely to avoid appearing difficult: ask questions, obtain missing information and understand that dissent activates the surveyor process rather than stopping the project.
This article concerns England and Wales. It provides general information, not legal advice. The application of the Party Wall etc. Act 1996 depends on the facts, ownership and proposed work.
Check the notice
Confirm the owner, property, section of the Act, description of work, proposed start and service details. A notice should match the current design.
Review risk and information
Ask for relevant plans, structural details, foundation depths, access proposals and insurance information. Consider the age and condition of your building and whether a schedule of condition would be useful.
Consent with safeguards
Written consent can record agreed working hours, protection, access, photographs and a contact route for damage. Conditions must be clear and accepted by the building owner.
What dissent means
Dissent does not amount to a planning objection or veto. It creates a statutory dispute so an agreed surveyor or separate surveyors can settle an award.
Frequently asked questions
What if I do not reply?
After the statutory response period, a dispute is generally deemed to have arisen and a surveyor may ultimately be appointed on your behalf following the required procedure.
Can I change my mind after consenting?
Consent and appointments can have significant consequences. Obtain advice promptly rather than assuming they can simply be withdrawn.
