Start a free quote →You need Party Wall Act notices if your Harrow project involves: building on or astride a boundary (Section 1), cutting into a party wall or party structure (Section 3), or excavating within 3m/6m of an adjoining property's foundations (Section 6). Most loft conversions, extensions and basement digs in Harrow trigger at least one section.
Our fixed fee for drafting and serving party wall notices in Harrow starts at £450 for a single adjoining owner. If your neighbour consents, that's the total cost. If they dissent, surveyor fees typically add £700–£1,000 per neighbour for the Award process. We include party wall notices in our Complete architectural packages at no additional charge.
If all adjoining owners in Harrow consent: 14 days (Section 3/6 notice) or 1 month (Section 1 notice). If they dissent and surveyors must be appointed, allow 6–8 weeks for the Award. We serve notices as early as possible so the process runs in parallel with your planning application.
No — starting notifiable works in Harrow before serving valid notices or obtaining a Party Wall Award is a breach of the Party Wall Act 1996. It can result in injunctions, damages and loss of your statutory protections. We ensure notices are served at the right time so your build timeline is not delayed.
If an adjoining owner in Harrow does not respond within 14 days, the Act deems them to have dissented. This triggers the surveyor appointment process — you appoint a surveyor, they can appoint their own (at your cost) or you can agree on a single 'agreed surveyor'. We manage this process and keep it moving.
