Decision : Closed after initial enquiries
Decision date : 29 Apr 2026
The Ombudsman's final decision:
Summary: We will not investigate this complaint about a council tax exemption. This is because the complaint is late and there are no good reasons for this.
The complaint
- Ms X complains the Council was wrong not to apply a Severe Mental Impairment council tax exemption for a period from 2012 to 2020. She says the Council should accept the evidence she provided.
The Ombudsman’s role and powers
- We cannot investigate late complaints unless we decide there are good reasons. Late complaints are when someone takes more than 12 months to complain to us about something a council has done. (Local Government Act 1974, sections 26B and 34D, as amended).
How I considered this complaint
- I considered information provided by the complainant and the Council. I also considered the Ombudsman’s Assessment Code.
My assessment
- Ms X complained to the Council regarding the matters in paragraph 1.
- The Council replied explaining why it required signed evidence from a GP that confirmed whether a person was severely mentally impaired and the effective date. The Council also explained the specific information required from a medical practitioner. It also stated how Ms X could appeal to the Valuation Tribunal.
- We will not investigate this complaint because it is late as it relates to a claim for an exemption starting 13 years before Ms X complained to the Ombudsman. There is no good reason for the delay in complaining to the Ombudsman.
- In addition, the Council has advised how Ms X can appeal to the Valuation Tribunal about its decision to refuse an exemption. It is reasonable to expect Ms X to appeal to the Valuation Tribunal.
Final decision
- We will not investigate Ms X’s complaint because it is late and there are no good reasons for this. She can appeal the Council’s decision not to apply an exemption.
