Council Tax Premium Exception Evidence Wales: What Each Class Requires

The exception classes exist in national legislation, but councils assess them locally — and they reject applications when the evidence is thin. Each class has a specific standard of proof, and understanding what the council is actually checking saves a round trip of rejection and resubmission.

Class 1 (Sale) and Class 2 (Let): The Reasonable Price Test

These are the most frequently claimed and most frequently refused exception classes. The evidence hurdle is the same concept in both: you must prove continuous, active, open-market marketing at a reasonable price or rent.

For a sale (Class 1), prepare:

• A signed estate agency instruction agreement showing the listing date
• Active online listing URLs on Rightmove, Zoopla, or OnTheMarket — screenshot them with visible dates
• The sales brochure or listing details
• A comparative market analysis from the agent, or an RICS valuation, showing the asking price sits within the range of recent Land Registry completions for similar properties in the same electoral ward
• Any price reduction history (demonstrates genuine effort to sell)

For a letting (Class 2), prepare:

• A signed letting agency marketing agreement
• Public rental listing URLs with dates
• A log of viewing appointments and enquiries
• Evidence that the asking rent matches local market rates (OpenRent, Rightmove rental comparables)

The "reasonable price" test is where councils push back hardest. They compare your asking price against actual Land Registry completions — not other asking prices. If your price is significantly above what similar properties have actually sold for, the council can refuse on the grounds that the marketing is not genuine.

Class 3 (Annexe): Structural Integration

You need to demonstrate the annexe forms part of, or is treated as part of, a main dwelling. Evidence includes:

• Council tax banding schedule showing the annexe is part of the same assessment
• Structural floor plans showing physical connection or integration
• Evidence of shared utility supply (water, electricity on one meter)
• Proof of integrated family use

Class 4 (Armed Forces): Posting Orders

The test is simple: the owner or tenant resides in MoD service accommodation and would otherwise use this Welsh property as their sole or main residence. Evidence:

• MoD occupancy agreement for the service quarters
• Official posting order or confirmation letter from the commanding officer

Class 7 (Job-Related): Contractual Obligation

This is the most strictly interpreted class. The council needs to see a genuine contractual obligation — not just convenience or proximity. Evidence:

• The employment contract with the residency clause
• A confirmation letter from the employer on headed paper
• For ministers of religion, the licence or appointment letter specifying the tied dwelling
• For directors, the company's articles of association and director's service agreement

A letter from a line manager saying "it's helpful for them to live near the office" does not meet the threshold. The contract itself must require residence.

Class 6 (Planning Restriction): The Decision Notice

Bring the original Town and Country Planning Act Decision Notice or Section 106 agreement. The council checks the specific wording — the condition must prevent occupation for a continuous period of at least 28 days in any 12-month period, specify holiday-let-only use, or prevent the dwelling from being occupied as anyone's sole or main residence. A restriction that only prohibits commercial sub-letting does not qualify.

What Happens After You Submit

Councils assess applications on the balance of probabilities. A complete and consistent evidence package helps address the facts the council must assess, but the council decides whether the legal criteria are met. To challenge a refusal, submit a formal written Section 16 grievance to the billing authority. If it rejects the grievance, you have two months from the date on the decision notice to appeal free to the Valuation Tribunal for Wales; if it does not respond within two months, the appeal must reach the tribunal within four months from the date you submitted the grievance.

The Wales Premium Exceptions Guide includes detailed evidence checklists for every class and a timeline tracker for the application and appeal process.
