Zack Polanski’s Houseboat Council Tax Controversy
5/14/2026, 10:41:02 PM
The Core Issue
Green Party leader Zack Polanski has acknowledged that, during his three-year residence on a narrowboat moored at Lee Valley Marina in east London, he may not have paid council tax on the vessel. The party says he has taken immediate steps to settle any liability and apologised for an “unintentional mistake”. Waltham Forest Council, which administers the borough, is reviewing the case and seeking legal advice.
Background & Context
UK guidance treats a boat as a taxable residence when it is the occupant’s “sole or main” home. Residential moorings normally incur council tax, whereas leisure-only moorings are exempt. The Lee Valley Authority limits permanent habitation on its marina.
Timeline
2023-2025 – Polanski and his partner live on the houseboat, advertising it as their “amazing home”. May 2026 – *The Times* reports possible non-payment and earlier claims of occasional use. 12 May 2026 – Green Party confirms recent residence and steps to pay tax. Same day – Labour chair Anna Turley requests a GLA investigation; Conservative chair Kevin Hollinrake labels the case “staggering hypocrisy”.
Data & Statistics
Tax lawyer Dan Neidle estimates liability at roughly £4,000-£4,300 for three years, based on Band A rates of £1,370-£1,518 per year plus a possible £70 penalty.
Official Statements & Responses
The Green Party said Polanski apologised sincerely for the unintentional mistake and has taken steps to pay any tax due, while refusing to disclose his address for security reasons. Waltham Forest Council said it is making assessments and taking legal advice with Polanski’s team. Labour chair Anna Turley wrote to the GLA, citing a possible breach of Section 106 of the Local Government Finance Act. Conservative chair Kevin Hollinrake described the episode as staggering hypocrisy.
Criticism & Opposition
Labour described Polanski as “caught red-handed”, while Conservatives accused him of hypocrisy and warned the incident damages public trust in a party that campaigns to raise council tax on second homes.
Conflicting Reports & Gaps
Green Party initially said the boat was used only occasionally; a sales advert and neighbour testimony suggest full-time residence. Electoral rolls list Polanski at a bungalow near the marina, raising questions about compliance with voting-address rules. Council has not confirmed liability.
