Council Tax Second Home Premium by Council — Cornwall, North Yorkshire, Devon and Beyond

The 100% second home council tax premium is discretionary — each billing authority in England decides independently whether to charge it, at what rate, and from which financial year. By April 2026, approximately 84% of English councils had activated the premium, but the financial impact varies enormously depending on where your second home sits.

A Band D second home in Cornwall faces a total annual bill of over £4,600. The same band in a lower-precept rural district might cost under £3,000 including the premium. Here's how the premium works across the areas where second home ownership is most concentrated.

Cornwall

Cornwall has the highest density of second homes in England — over 13,000 properties classified as second homes across the county. Cornwall Council adopted the 100% premium effective 1 April 2025, one of the first wave of councils to use the power.

The average Band D council tax in Cornwall (including all precepts) was approximately £2,303 in 2026/27. With the 100% premium, a Band D second home pays roughly £4,606. Cornwall runs a dedicated "Second Homes Review Form" through its online revenues portal, and it has been one of the most active councils in requesting detailed evidence for Class G and Class H marketing exceptions — expect to provide estate agent contracts, portal listing URLs, and asking price justifications backed by comparable local sales.

Cornwall also has a significant population of holiday let owners affected by the separate VOA business-rates tests: 140 nights available and 70 nights actually let in the preceding 12 months, plus availability for 140 nights in the coming 12 months. Properties that can't meet the letting threshold return to the council tax list and face the second home premium retroactively.

North Yorkshire

North Yorkshire Council (the unitary authority created in April 2023, replacing the former county council and seven district councils) adopted the 100% premium from 1 April 2025. Second homes are concentrated in the Yorkshire Dales, Scarborough coast, and Harrogate district.

The council portion of Band D was approximately £2,036 in 2026/27 before parish precepts, meaning the total with a 100% premium can exceed £4,072.64 depending on parish precepts. North Yorkshire enforces strict checks on Yorkshire Dales principal residency planning restrictions versus seasonal exceptions under Class L — if your property in the Dales has a planning condition restricting year-round occupation, gather the planning decision notice before applying.

Devon (East Devon, North Devon, South Hams, Teignbridge)

Devon's second home premium is charged by individual district councils, each with its own adoption date and evidence procedures. East Devon adopted the 100% premium for 2025/26; check the current policy for other Devon districts before assuming a premium applies.

South Hams and the broader Dartmouth/Salcombe corridor have some of England's highest property values, so the premium on upper-band homes (Bands F, G, H) represents a substantial annual cost. Teignbridge published a detailed policy impact report documenting its local database classifications and revenue effects — useful reading if you want to understand how your council categorises properties.

Devon also has a large population of holiday cottage owners, many operating through agencies. The distinction between a holiday let (potentially on business rates) and a second home (on council tax with the premium) depends entirely on meeting the VOA's tests: 140 nights available and 70 nights actually let in the preceding 12 months, plus availability for 140 nights in the coming 12 months.

Lake District (Westmorland and Furness / Cumberland)

The former Cumbria county council area was reorganised into two unitary authorities in April 2023: Westmorland and Furness (covering the southern Lake District, South Lakeland, and Barrow) and Cumberland (covering Allerdale, Carlisle, and Copeland). Check the relevant authority's current policy to confirm whether the premium applies.

The Lake District's second home density is among England's highest, particularly in Ambleside, Windermere, Keswick, and the Borrowdale valley. Many properties in the Lake District National Park carry planning restrictions on permanent residential occupation — making Class L a commonly claimed exception in this area.

Norfolk and Suffolk

The Norfolk and Suffolk coasts — particularly the stretch from Wells-next-the-Sea through Blakeney to Aldeburgh — have high concentrations of second homes. Check the relevant billing authority's current policy to confirm whether the premium applies.

Many second homes in this region are traditional flint cottages or converted fishermen's houses bought as weekend retreats. The premium is pushing some owners toward the holiday let route, but meeting the 70-night actual letting threshold in areas with a short summer season is harder than in year-round tourist destinations like Cornwall.

Dorset and Somerset

Dorset Council (the unitary authority covering most of the county outside Bournemouth, Christchurch and Poole) and Somerset (now a unitary authority after the 2023 reorganisation) set local premium policies for their areas. Check the current policy for the property's billing authority before assuming the premium applies.

How Exception Applications Differ by Council

While the nine statutory exception classes under SI 2024/1007 are nationally mandated, each council runs its own application process:

• Cornwall has the most developed online system with a dedicated second homes review form
• North Yorkshire uses an online revenues contact form plus paper exception declarations
• East Devon runs a general council tax exception application portal
• Preston (an early adopter with detailed published policy) offers an "Empty & Second Home Exception Form"

In every case, the underlying legal test is identical. A Class G marketing exception in Cornwall requires the same evidence as in North Yorkshire — a signed estate agent contract, live portal listings, and a reasonable asking price. Only the submission method varies.

The Financial Case for Acting

The premium can add thousands of pounds per year to your council tax bill. A successful exception removes the premium amount on that bill; with a 100% premium, the saving depends on the property's council tax band and local charge. Against a one-off investment in getting the claim right the first time, the return is substantial.
