What Is a Barnet Party Wall Surveyor?

A party wall surveyor is a specialist who manages the legal and technical process between neighbours when building work affects a shared wall or boundary structure. They act as an impartial expert — or in some cases, as a representative of one party — to make sure everyone’s rights are protected before work begins.

At AC Design Solution, our expert party wall surveyors are members of the Institute of Party Wall Surveyors, with hands-on experience across hundreds of residential and commercial properties throughout Barnet and beyond.

I appointed AC Design Solutions for a challenging new build project - demolishing an existing house and replacing it with 7 new flats in Isleworth. The team provided a comprehensive service including architectural design, structural engineering calculations, building regulations drawings, and preparation of all the technical reports required for planning (drainage, energy, daylight/sunlight, arboricultural, etc.). The project was taken to Hounslow Planning Committee and we achieved unanimous approval on the first attempt. AC Design Solutions were very responsive throughout, handled all the pre-application consultations, and prepared a strong case that addressed all the planning concerns. Their knowledge of local planning policies and building regulations was excellent, and they coordinated all the specialist consultants we needed. The building regulations drawings were detailed and compliant, ready for submission. I would highly recommend AC Design Solutions for residential development projects in West London. Really pleased to have these guys on my team - they are absolutely on the ball, and I look forward to doing many more projects with them in expansion of my portfolio.

Had a great experience with AC Design, the customer service was great and they responded to our questions promptly. Turnaround for designs were quick too. I especially appreciated having a call with the engineer as it helped us understand why the designs were constructed in a certain way. Highly recommend this company if you require structural drawings done

Why Do You Need a Party Wall Surveyor for Your Building Project?

How Does the Party Wall Agreement Process Work?

1

1

Step 1: Serving the Notice

The first step is serving a formal party wall notice on every adjoining owner affected by the proposed works. Depending on the type of building work, this could be a Party Structure Notice, a Line of Junction Notice, or a Three/six  Metre Notice for excavation near a neighbouring property.

Notices must be served at least two months before work begins for most notifiable works. We handle this for you  correctly and on time.

Step 2: Appointment of Surveyors

Once a notice is served, the adjoining owner has the right to consent or dissent. If they dissent, both parties must appoint surveyors. You and your neighbour can agree on a single chartered surveyor, or each appoint their own. Where separate surveyors are appointed, a third surveyor may be selected to resolve any disagreement between them.

Step 3: Creating a Party Wall Award

The surveyors prepare a party wall award — the legally binding document that outlines how the works will be carried out, working hours, access arrangements, and what happens if damage occurs. A thorough schedule of condition is attached, recording the existing state of the adjoining property before work begins.

Step 4: Commencement of Work

Once the party wall award is agreed and signed, work can begin. Throughout the project, the award provides a clear framework that helps avoid disputes and keeps things moving. If something unexpected happens, the process for resolving it is already in place.

Frequently Asked Questions

What Is the Party Wall Act and Why It Matters for Barnet Party Wall Projects?

The Party Wall etc. Act 1996 governs building work that affects shared walls, boundary structures, or involves excavation near a neighbouring property. It applies across England and Wales including the entire London Borough of Barnet.

The Act protects both the building owner and the adjoining owner. It gives neighbours a formal way to raise concerns, ensures damage is properly documented, and sets out a clear process for resolving party wall matters without going to court.

How Much Does a Party Wall Agreement Cost in Barnet?

Costs vary depending on the complexity of the proposed works, the number of adjoining owners affected, and whether the parties agree on a single chartered surveyor or appoint separate ones. Simple cases with a single adjoining owner and an agreed surveyor tend to be the most cost-effective.

Contact AC Design Solution for a clear, upfront quote tailored to your specific building project in Barnet.

When Should You Hire a Party Wall Surveyor in Barnet?

The short answer: before you start anything. Party wall notices must be served at least two months before most notifiable works begin. Leaving it too late can cause costly delays to your programme.

If you’re planning a loft conversion, rear extension, side extension, basement conversion, or any excavation near a neighbouring property, speak to us as early as possible  ideally at the design stage.

How Long Does the Party Wall Process Take?

If your neighbour consents immediately, the process can be completed in a matter of weeks. If they dissent and separate surveyors are appointed, preparing and agreeing the party wall award typically takes four to eight weeks. Complex cases with multiple adjoining owners or disputed works can take longer.

Starting early is always the right move.

How Can You Look After Your Neighbours and Still Protect Yourself?

The party wall process, done properly, isn’t adversarial. A well-prepared schedule of condition protects both sides. Clear communication, managed by an experienced party wall surveyor, keeps relationships intact throughout the project.

We always recommend talking to your neighbours before serving formal notice. A brief conversation explaining your building project goes a long way. Our team can advise on how to approach this and we handle all the formal steps from there.
