The short answer
Enforcing a party wall award is usually more straightforward and cheaper than a full civil claim, but it is not cost-free. The cost depends mainly on whether the other owner complies after a formal letter or contests the process.
Why it matters
Enforcement most often arises where the building owner has not paid fees or compensation, but can also relate to access or remedial works. Where the breach is clear and not seriously contested, the likely outlay is around £500 to £2,000 — a letter before action, court fee and basic legal assistance. If the other owner disputes the award, argues validity or resists, costs can reach £5,000 to £10,000 or more, especially with solicitors, counsel and surveyor evidence. A simple process may take two to six months; a contested one longer, particularly with an appeal or jurisdictional point. If enforcement succeeds the defaulting owner may be ordered to pay costs, but the enforcing owner usually pays first and recovers later.
What to do now
- Budget at least a few thousand pounds where lawyers are involved, and more if contested.
- Start with a clear letter before action — many breaches resolve there.
- Expect to fund the process upfront and recover costs later.
Common mistakes
- Assuming enforcement is free or instant.
- Skipping the letter before action.
- Forgetting the upfront cashflow even where costs are later recoverable.
