Airbnb Rules — Thundersley, United Kingdom | Permits, Caps, Taxes (2025)

What are short-term lets?

Short-term letting of a dwelling as visitor accommodation on a commercial basis for short periods with high guest turnover (may be treated as serviced accommodation/C1 or sui generis rather than C3).

Are short-term lets legal?

Short-term lets are legal in Thundersley, but you may need planning permission if a C3 dwelling is run as visitor accommodation (serviced accommodation/C1 or sui generis) on a frequent basis. There’s no citywide night cap. Report income to HMRC; if the property is available 140+ days and actually let 70+ days it may be moved from Council Tax to Business Rates. No local tourist levy.

Rent-a-Room (main home only): Up to £7,500 tax-free when letting a furnished room in your only or main home (shared → £3,750 each). Not for whole-home STRs.
