The Statutory Referendum Threshold: Localism Act 2011 Explained
Before 2011, central government used ministerial 'capping' powers to arbitrarily intervene and force councils to rerun budgets if ministers deemed increases excessive.
Chapter 1 of Part 5 of the Localism Act 2011 fundamentally reformed this system by inserting Section 52ZB into the Local Government Finance Act 1992. This established a statutory principle: local residents must be given a direct, legally binding democratic vote if a council seeks to raise Council Tax above a threshold determined annually by the Secretary of State.
Each winter, Parliament approves the Local Government Finance Settlement, establishing the percentage limits for the upcoming financial year beginning on 1 April.

| Police & Crime Commissioners (PCCs) | Cash threshold (typically £13.00 to £15.00) | N/A | Statutory annual cash ceiling | Mandatory referendum if increase exceeds the gazetted cash precept limit |
| Fire and Rescue Authorities | Up to 2.99% | N/A | 2.99% total increase | Mandatory referendum if precept increase exceeds 2.99% |
| Parish and Town Councils | No statutory cap (Uncapped) | N/A | Unlimited by percentage | Exempt from referendum rules under current legislation |
What Happens If a Council Triggers a Referendum?
If a council's elected cabinet votes to set a budget exceeding the statutory threshold, strict legal obligations apply under Section 52ZG of the 1992 Act.
The authority must prepare two concurrent budgets: (1) The proposed 'excessive' budget, and (2) A 'substitute' budget that complies with the non-referendum threshold.
The council must organize and fund a local referendum, typically held on the first Thursday in May alongside local municipal elections. If the referendum fails (i.e. more than 50% vote 'No'), the council is legally compelled to revert to the substitute budget immediately and reissue revised demand notices to every household, refunding any overpayments.
Running a local referendum costs an authority between £300,000 and £1,200,000. In 2015, the Bedfordshire Police and Crime Commissioner held the only modern precept referendum, asking for a 15.8% increase; the public overwhelmingly voted against it by 69.5% to 30.5%. Almost all councils avoid referendums to prevent costly electoral defeat.
Section 114 Bankruptcy Notices & Special Ministerial Dispensations
In recent years, several English councils—including Birmingham City Council, Thurrock Council, Slough Borough Council, Croydon Council, and Woking Borough Council—issued notices under Section 114 of the Local Government Finance Act 1988, declaring that their projected expenditure exceeded available financial resources.
Under Section 52ZZ of the 1992 Act, the Secretary of State has exceptional statutory authority to grant specific councils permission to raise Council Tax by 9.99% or even 14.99% without holding a local referendum.
These dispensations are reserved for councils in severe financial distress under government-appointed commissioners attempting to stabilise municipal debts.
Why Your Final Council Tax Bill Often Increases by More Than 4.99%
Many taxpayers are puzzled when their total annual demand notice displays an overall increase greater than 4.99%, even when their principal council stayed within the statutory limit.
This occurs because of two structural factors:
