Council Tax Premium Seasonal Class L Exception — Planning Restrictions That Block the Surcharge

Some properties were never meant to be lived in year-round. A coastal chalet with a planning condition that bans occupation between November and March, a holiday park lodge with a condition preventing occupation for a continuous period of at least 28 days in a year, a conversion where the original consent said "holiday use only" — these dwellings exist under legal constraints that make permanent residence impossible. Yet without the right exception, the council sends them a 200% council tax bill just the same.

Class L of the Council Tax (Prescribed Classes of Dwellings and Consequential Amendments) (England) Regulations 2024 (SI 2024/1007) prevents the 100% second home premium from being applied to these properties.

What Class L Requires

Class L applies to furnished second homes where a formal Town and Country Planning Act decision notice does at least one of the following:

• Prevents occupancy for a continuous period of at least 28 days in any one-year period
• Specifies the dwelling may be used for holiday lets only
• Prohibits occupation as a person's sole or main residence

The key word is "formal." The restriction must appear in a formal planning instrument, such as a decision notice issued by the local planning authority or a Section 106 agreement. A voluntary decision to close up a cottage during winter doesn't count. Nor does a site owner's park rules handbook or a management company's occupancy guidelines — the restriction has to come from the planning system.

Where Class L Typically Applies

The most common scenarios:

Holiday park chalets and lodges — Some holiday parks have planning conditions that prevent occupation for a continuous period of at least 28 days in a year, restrict the dwelling to holiday use only, or prohibit its use as a sole or main residence. If your lodge has one of these conditions, Class L may apply.

Coastal and rural conversions — Properties converted from agricultural buildings or workshops sometimes carry "holiday use only" conditions in the original planning consent. The local planning authority restricted the use class to prevent permanent residential settlement in areas where it might not be appropriate.

Self-build seasonal homes — Occasionally, planning permission for a dwelling includes a condition that it cannot be anyone's sole or main residence, typically in national parks or AONBs where the authority wanted to allow a holiday property but not a permanent home.

Evidence You Need

The evidence for Class L is unusually specific — you need the planning decision notice itself:

• Planning decision notice or Section 106 agreement from the local planning authority showing the occupancy restriction (the condition number and wording that prevents occupation for a continuous period of at least 28 days in any one-year period, restricts the dwelling to holiday use only, or prohibits use as a sole or main residence)
• Planning reference number so the council can verify the condition against their own records

Unlike other exception classes where you're assembling a dossier of financial documents and agent contracts, Class L is essentially a document lookup. The planning condition either exists or it doesn't. If it does, the exception is mandatory and has no time limit.

What Class L Does Not Cover

Class L does not apply to:

• Properties where the owner simply chooses not to live year-round — Voluntarily leaving a cottage empty from October to April is not a planning restriction
• Properties with expired or varied planning conditions — If the condition was removed through a Section 73 application or a Certificate of Lawful Development, Class L no longer applies
• Holiday lets on business rates — If your property already transferred to the non-domestic rating list through the VOA tests (140 nights available and 70 nights actually let in the preceding 12 months, plus availability for 140 nights in the coming 12 months), it's not on the council tax list at all and Class L is irrelevant

The distinction between Class L (planning-restricted seasonal properties staying on council tax) and the business rates route (commercially let holiday properties moving off council tax entirely) confuses many owners. Class L is for properties with a legal restriction on occupation. The business rates route is for properties actively run as a letting business that meet the VOA's availability and letting thresholds.

How to Apply

Submit your Class L claim to the billing authority for the area where the property sits. Attach the planning decision notice showing the relevant condition. The council can also verify the condition through their own planning records if you provide the reference number.

Class L has no time limit — it runs indefinitely while the planning condition remains in force. If you've been charged the premium since April 2025 and the planning restriction was already in place, you can request backdating and a refund.

If the council rejects your claim, check the exact wording on the planning notice. Councils occasionally misinterpret conditions that limit "residential use" versus conditions that limit "occupation." A Section 16 appeal to the Valuation Tribunal for England (free) is the formal route to challenge a refusal.

Finding Your Planning Condition

Not sure whether your property has a relevant planning restriction? Start with the local planning authority's online planning register — search by address or postcode. The decision notice for the original consent (or any subsequent variations) will list all conditions. If the property is on a holiday park, the park operator should also hold the planning permission for the site.
