Spelthorne council in 'critical financial position' as extreme levels of debt reach 'unsustainable' heights
Spelthorne’s financial crisis is “even more critical”, with millions in cuts needed to avoid catastrophic bankruptcy, according to a new report.
Best value inspectors were called in to review the council’s finances in May 2024 in light of extremely high levels of debt and borrowing. Spelthorne’s debt reached £1.096 billion in March 2023 – the second highest level of debt for a district council in England at the time.


The findings of the inspection have been published on Monday (March 17). The report highlights that the council “is in a critical financial position, burdened by unsustainable debt levels, significant investment risks, and systemic governance weaknesses”.
Between 2016 and 2018, Spelthorne Borough Council borrowed around £1 billion to invest in a commercial portfolio of Grade A office buildings and residential land in and around the borough. But slow progress on regeneration and housing projects highlights a limited understanding of regeneration delivery as well as finance and risk, the inspectors said.


Best Value Inspectors concluded: “The council’s use of its resources is inadequate”. In the damning report, they said Spelthorne’s approach to property acquisitions “lacked due regard to long-term planning and risk management” and had an “overly-optimistic reliance on consistency” of the market that the Council first entered.
The report said: “The combination of voids, expiring leases, and falling income streams from the investment portfolio threatens the stability of its budget. Adding to the strain are the ongoing revenue costs of housing and regeneration projects, which were suspended in late 2023. Despite these mounting financial pressures, no clear path forward has been outlined to address them.”
The recovery process will be overseen by government-appointed commissioners. Minister of State for Local Government and English Devolution, Jim McMahon, wrote to leader Cllr Joanne Sexton to say the local authority is failing in its ‘best value’ duty to residents, essentially meaning the authority is defecting on its ability to make decisions that are economic, efficient and effective and work towards continuous improvement.
Inspectors said the council has a “poor record” of fully and effectively implementing recommendations from external reviews. The report read: “Senior officers display an optimism bias and a lack of awareness of the true situation facing the council. We do not believe the council has the capacity and capability to make the urgent changes needed without significant external support.”


Both the inspection and the recent external audit found errors in the council’s financial practices including the miscalculating the minimum amount Spelthorne needs to keep paying back its debt, incorrectly classifying expenses as assets, further undermining the revenue budget.
“The outline budget report for 2025/26 to 2028/29 presented to members on December 9, 2024 shows the need to deliver £8.6 million in savings by 2028/29, equating to 64 per cent of the council’s core spending power for 2024/25, or 33 per cent of the net budget, assuming contributions from commercial income. In our view, even these projections are understated. Despite this, we have seen no credible strategy in place to achieve savings of this level,” said the report.
Leader of Spelthorne Borough Council, Cllr Joanne Sexton, said, “This Group Administration has faced a challenging time and has been actively pursuing the right solution to manage the historical debt that it has inherited. We have met with the Local Government Minister from central government, and we have agreed to work in partnership to take decisive action in the remaining time we have before local government reorganisation is implemented. Our pledge remains that we will always put residents at the heart of everything we do.”
The council’s senior management team also came in for criticism in the report. Inspectors said the team seemed “overly confident” and “appear to underestimate the scale of the financial risks”. Member challenges remain “limited” according to the report, with many councillors not fully understanding the risks at hand. Inspectors highlighted there was a “wider breakdown” of relationships between senior management and the political leadership.
The findings of the inspection highlight the council is failing to meet best value standards in five critical areas:
- Use of Resources;
- Continuous Improvement;
- Governance;
- Leadership;
- Culture.
