Choosing the right party wall surveyor can make the difference between a smooth building project and a nightmare of delays, disputes, and excessive costs. Whether you're the building owner undertaking works or the adjoining owner protecting your property, selecting a qualified, experienced surveyor is crucial. This comprehensive guide tells you exactly what to look for.

Key Fact: As the adjoining owner, your surveyor's fees are paid by the building owner (your neighbour). This means you can appoint the best surveyor available at no cost to yourself.

Essential Qualifications and Accreditations

Must-Have Qualifications:

Why Qualifications Matter:

Warning: Anyone can call themselves a "party wall surveyor" – the title isn't protected. ALWAYS check for RICS, CIOB, or RPSA membership. Unqualified "surveyors" are a major cause of disputes and delays.

Experience Matters: What to Look For

Specific Party Wall Experience:

Red Flags – Avoid Surveyors Who:

  • Aren't RICS, CIOB, or RPSA qualified
  • Offer "cheap" fees significantly below market rates
  • Promise they can "get your neighbour to agree"
  • Have no professional indemnity insurance
  • Operate without a fixed office address
  • Can't provide references or examples of past awards
  • Pressure you to use specific builders
  • Suggest skipping proper procedures to "save time"

Agreed Surveyor vs. Appointing Your Own

Option 1: Agreed Surveyor (One Surveyor for Both Parties)

How it works: Both building owner and adjoining owner agree to appoint the same surveyor who acts impartially for both.

Advantages:

Disadvantages:

Best for: Simple projects, cooperative neighbours, straightforward works (single steel beam, minor extensions)

Option 2: Separate Surveyors (Each Party Appoints Own)

How it works: Building owner appoints their surveyor; adjoining owner appoints theirs. Both surveyors negotiate and agree the award together.

Advantages:

Disadvantages:

Best for: Complex projects, basement excavations, when parties don't trust each other, high-value properties

Recommendation: For basement excavations, underpinning, or major structural works, always appoint your own surveyor. The extra cost is worthwhile for dedicated representation.

Frequently Asked Questions

Can I change my party wall surveyor mid-process? +

Yes, you can replace your surveyor at any time, but you'll need to give formal notice to all parties. The new surveyor will need to catch up on the process so far. It's best to choose carefully from the start to avoid this disruption.

Should I use my neighbour's suggested surveyor? +

Only if you're comfortable using an Agreed Surveyor arrangement. If your neighbour suggests a surveyor, research them independently – check qualifications, experience, and get your own quote. You have the right to appoint anyone you choose.

What if I can't afford a party wall surveyor? +

If you're the adjoining owner, you DON'T pay – your neighbour (the building owner) pays your surveyor's fees. This is a legal requirement. If you're the building owner, surveyor fees are a necessary cost of your project – budget for them alongside other construction costs.

Can my builder act as the party wall surveyor? +

Absolutely not. This is a serious conflict of interest. Party wall surveyors must be independent and impartial. Using your builder would undermine the entire process and likely invalidate any award prepared. Always use an independent qualified surveyor.

How do I verify a surveyor's qualifications? +

Check the RICS website (rics.org) for their member directory. You can verify RICS membership and check for any disciplinary actions. Similarly, CIOB has a member directory. Ask to see their membership certificate and professional indemnity insurance certificate.
