For most homeowners planning a standard extension or loft conversion, it isn't. This is the point that some in the industry don't want you to clearly understand — because the Award is where the fees are.
The Party Wall etc. Act 1996 doesn't require a Party Wall Award in every case. It requires a correctly served notice. What happens next depends on your neighbour's response — and there are three possible outcomes, only one of which involves a formal Award.
The three outcomes
Outcome A — Your neighbour consents
Applies to approximately 45% of all party wall notices
Your neighbour receives the notice, understands what it means, and signs the consent form. Once the relevant notice period has run — one or two months depending on the works — you can start. No surveyor appointment. No Award. No further cost beyond the notice itself.
Around 45% of party wall notices result in this outcome. A clearly worded, professionally prepared notice is the single biggest factor in achieving it.
Total cost: from £30
Outcome B — Your neighbour consents subject to a Schedule of Condition
The most common outcome for standard domestic projects
Your neighbour is happy for the works to proceed, but wants a record made of their property's condition before you start — so that if anything is damaged during the works, there is an unambiguous photographic baseline to refer to.
This is entirely reasonable, and it is exactly what the Act's protections are designed to deliver. A qualified, trained, experienced surveyor visits the adjoining property, photographs and documents its condition thoroughly, and produces a formal Schedule of Condition report. Both you and your neighbour receive a copy. This gives both parties full legal protection. Your neighbour is protected against damage going unrecorded or uncompensated. You are protected against exaggerated or false claims about pre-existing defects.
Works then proceed without a Party Wall Award, without ongoing surveyor involvement, and without the costs that go with it.
For the vast majority of domestic extensions and loft conversions on terraced or semi-detached properties, this is the most appropriate and proportionate outcome. It delivers everything the Act was designed to achieve, at a fraction of the cost of the full Award process.
Total cost: from £30 plus the Schedule of Condition survey fee
Outcome C — Full dispute / Party Wall Award required
Applies where there is genuine dispute, or specific requirements need to be formally determined
If your neighbour dissents — or fails to respond within 14 days, which counts as a deemed dissent — the formal dispute resolution process begins. Surveyors are appointed, and a Party Wall Award is drawn up setting out the conditions under which the works are to be carried out.
This is the more costly route, and it exists for good reason. A Party Wall Award may be necessary and appropriate where there is genuine dispute between the parties about the works or their scope, where specific access requirements, working method conditions, or protective measures need to be formally determined and recorded, where the relationship between neighbours makes an informal agreement unsuitable, or where the nature or complexity of the works demands formal legal certainty for both parties.
In those circumstances, an Award provides exactly that certainty — and our panel includes surveyors whose professional qualifications and memberships include RICS, the Faculty of Party Wall Surveyors, and the Pyramus & Thisbe Society. They are there to support you through the process. Every surveyor on our panel is bound by the requirement to charge reasonable fees for any ongoing services.

Which outcome is most likely for your project?
For a standard rear extension, single or two-storey, on a terraced or semi-detached property with a reasonable neighbour relationship — Outcome A or B is the most likely result. The full Award process affects a minority of domestic projects.
The most important thing you can do to maximise your chance of Outcome A or B is serve a correctly prepared, professionally worded notice that gives your neighbour confidence in the process from the start.
That's what we built this platform for.
Frequently asked questions
Is consent subject to a Schedule of Condition legally binding?
Yes. The consent and the request for a Schedule of Condition together constitute a formal record under the Act. Both parties are protected, and works can proceed on that basis without a Party Wall Award.
Can my neighbour change their mind after consenting?
Once consent has been given in writing, it is valid. If your neighbour later raises concerns about damage, the Schedule of Condition is the reference point — which is precisely why it provides such effective protection for both parties.
What if my neighbour asks for a Schedule of Condition — do I have to agree?
A request for a Schedule of Condition is entirely reasonable and in both parties' interests. It is not a dissent and does not trigger the formal Award process.
What if I'm not sure which outcome applies to me?
Start by generating your notice correctly and serving it. The response you receive determines the outcome. If your neighbour dissents or fails to respond, we'll explain exactly what happens next and connect you with the right panel surveyor for your area.
