Council Tax: The Hidden Care Crisis Driving Bills Up

Council Tax Is Quietly Becoming a Care Tax — And Most People Have No Idea

Council tax is one of the most visible taxes British households pay. It lands on your doormat. You set up a direct debit. You notice when it goes up. Between 2020 and the current financial year, the average council tax bill across England, Scotland, and Wales has risen by 30.8% — that's an extra £565 per year on the average household's bill. Yet roads stay potholed, libraries cut their hours, and local swimming pools quietly close. The instinctive reaction is to blame incompetent councils. The reality is more structural, more expensive, and more politically inconvenient than that.

The council tax system has two distinct crises running in parallel. The first is how councils are funded. The second — and far less discussed — is what they are now legally required to spend that money on. Understanding both is essential if you want to make sense of why your bill keeps rising, why some of the UK's wealthiest postcodes pay less council tax than struggling coastal towns, and why even well-managed councils are buckling.

Why Council Tax Varies So Wildly by Postcode

Council tax is, by design, a postcode lottery. Start with the most glaring structural flaw: the bands. Properties in England and Scotland are banded based on their estimated value in 1991. Wales updated its valuations in 2003 but has not revisited them since. That means a £100 million Mayfair mansion and a £500,000 semi-detached in Salford can theoretically sit in identical council tax bands — because property prices since the early 1990s are simply ignored.

For properties built after 1991, the Valuation Office Agency uses a process called comparative valuation — essentially working backwards to estimate what a property would have been worth in 1991, then assigning a band accordingly. It is a system that was already creaking when it was introduced and has only grown more absurd as UK property values have diverged sharply across regions over three decades.

Band D is the critical reference point. Every council sets its Band D rate, and all other bands are fixed as a legal percentage of that figure. But even Band D is not uniform within a local authority — Westminster, for example, charges different rates depending on whether you live in Queen's Park or Montpelier Square.

The geographic disparity is striking:

• Croydon has seen the largest increase since 2020: up approximately £816, a 45.7% rise.
• Wandsworth, a short distance away, has seen an increase of just £228 over the same period.
• Dorset Council holds the highest Band D rate in England.
• Westminster, the City of London, and Kensington and Chelsea — home to some of the most expensive real estate on the planet — all sit in the bottom five for total council tax paid.

This is not a coincidence. Wealthier boroughs typically generate stronger business rate revenues from thriving commercial districts, which reduces their dependence on council tax income. Adult social care — the single largest cost for most councils — is also means-tested, meaning fewer residents in high-wealth areas qualify for council-funded support. Both factors structurally suppress council tax bills in affluent areas while concentrating pressure on councils serving less wealthy populations.

The Austerity Decade Left Councils Structurally Weakened

To understand why bills are rising now, you need to understand what happened to council funding in the 2010s. The Institute for Fiscal Studies (IFS) data is unambiguous: local councils lost 26% of their funding per person in real terms across the austerity decade. Central government grants — one of the three main revenue streams alongside council tax and business rates — fell by 46% in real terms during that period.

Councils were offered a partial lifeline through a freeze scheme running from 2011 to 2016. Freeze your council tax and the government would compensate you with a grant worth a 2.5% rise each year. Most councils accepted. But that sweetener was cut to 1% from 2013, and the compensation never fully covered the shortfall. Around 40% of councils rejected the freeze entirely and began raising council tax rates during this period.

From 2016 onwards, caps evolved into a layered system. Currently, most councils are capped at a total increase of 5% per year — combining a core cap and an additional adult social care precept — unless they trigger a public referendum to go higher. Unsurprisingly, almost no council holds a referendum. The result: over 90% of councils raise bills to the maximum permitted level every single year.

What looks like one charge on your bill is actually several bundled together. These are called precepts. Your police authority sets its own increase. So does fire and rescue. A mayoral precept, a social care precept — each organisation sets its own rate. A council can truthfully claim it only raised its core charge by 2% even as your overall bill rises by 5% or more. Technically accurate. Functionally misleading.

The Real Reason Bills Keep Rising: Social Care Is Consuming Council Budgets

Funding levels matter, but they only tell half the story. The more important question is: what are councils actually spending money on?

In 2010, roughly 41 pence in every pound of council spending went on social care. By 2020, that had risen to 57 pence. The IFS now estimates that adult and acute children's social care accounts for around 65% of councils' non-education spending in England — up from 50% in 2010. In some areas, particularly seaside towns and retirement communities with older demographics, that figure can be even higher.

The legal context matters enormously here. Under the Care Act 2014, councils are legally required to fund eligible social care. This is not discretionary spending that can be trimmed when budgets tighten. The fire service, bin collections, libraries, and street lighting all come after this statutory obligation is met.

The pressures within social care are accelerating across two main areas:

Adult social care covers elderly people in residential care homes and working-age adults with learning disabilities, physical disabilities, and mental health needs. Demand is rising with an ageing population and increasing complexity of need. Costs are rising with wage pressures on care workers and the dominance of private providers in the market.

Children's services tell an even sharper story. In 2018-19, councils in England funded approximately 120 children's residential placements costing around £10,000 per week or more. By 2022-23, that figure had risen to over 1,500 placements. Most children's homes that were once run by councils or charities are now operated by private equity-backed firms. The Competition and Markets Authority found profit margins of around 20% or higher among the largest providers. When a child needs an emergency placement, the council has virtually no bargaining power. The bill is whatever the provider charges.

Homelessness costs have followed a similar trajectory. In 2015-16, homelessness accounted for 18% of councils' housing budgets. By 2023-24, it was 60%. There are now over 134,000 households in temporary accommodation in England, including more than 176,000 children — the highest number on record. These are overwhelmingly UK residents priced out of the private rental market, not asylum seekers (who are housed centrally by the Home Office).

The compounding effect is severe. More money is being swallowed by statutory care obligations before it ever reaches the visible services people associate with their council tax bill. A council can receive more funding and simultaneously deliver worse public services — not because of incompetence, but because demand for legally-mandated services is rising faster than income.

When Councils Fail: Section 114 and the Bankruptcy Question

Some councils have made genuinely poor financial decisions that have accelerated their crises. Croydon is the most prominent example. It tops the council tax increase table not only because of rising care commitments, but because of a series of bad investments — most notably the collapse of its Brick by Brick housing developer, which alone cost the council approximately £68 million. Croydon has issued multiple Section 114 notices, the local government equivalent of declaring it cannot balance its books.

Birmingham — the largest local authority in Europe — issued a Section 114 notice in 2023. Triggers included a substantial equal pay liability and an Oracle IT system whose projected cost of £19 million ballooned to potentially over £200 million.

A Section 114 notice does not mean a council goes bankrupt in the conventional sense — councils cannot simply close down. But once issued, all non-essential spending must stop, and government commissioners typically step in. For residents, the practical result is severe service cuts and, almost invariably, above-cap council tax increases granted by special government dispensation.

Bad decisions matter. But bad decisions alone cannot explain a nationwide pattern of rising bills, increased funding, and declining services. The structural problem — the growing dominance of social care costs — runs across well-managed and poorly-managed councils alike.

Why the System Needs Reform — And What That Should Look Like

The council tax system has two fundamental flaws that compound each other.

The first is the valuation problem. A property tax based on 1991 valuations is not a rational basis for local government finance in modern Britain. The relationship between council tax paid and property value is increasingly arbitrary, and the system entrenches geographic inequality rather than addressing it.

The second is the structural mismatch between what council tax is perceived to fund and what it actually funds. Most households understand council tax as payment for local services — bin collection, street lighting, parks, libraries. Increasingly, it is functioning as a local care levy — funding statutory obligations that vary enormously by area demographics but are set nationally by law.

Poorer areas with older or more vulnerable populations face higher care demands. They also typically have weaker business rate bases and lower property values, which limits their ability to raise revenue. The result is a compounding disadvantage: less money, higher demand, fewer resources for economic regeneration, which in turn suppresses future revenue. A closed pier means fewer tourists, struggling local businesses, lower business rates, and even less money for the care commitments that closed the pier in the first place.

The logical policy response — one that several analysts and economists have argued for — is to fund social care more like the NHS: nationally funded and nationally guaranteed, but locally managed and delivered. We do not ask Hartlepool to fund its own A&E department from local taxation. The case for treating social care differently is increasingly difficult to make.

Beyond that, updating property valuations to reflect current market realities — rather than a world that existed before the internet, before several property booms, and before devolution — would make council tax a more rational and defensible tax. If the objective is a form of wealth tax tied to property, the valuations should at least reflect actual property wealth.

What This Means for Your Household Right Now

If your council tax bill feels disconnected from the services you receive, that is because the connection has genuinely weakened. Here is what the data tells you:

• Your bill will almost certainly rise by close to 5% this year and next, because the vast majority of councils are raising to the cap.
• Where you live matters more than almost any other factor in determining how much you pay and how much it has increased.
• The trajectory of social care costs shows no signs of reversing. An ageing population and rising complexity of need mean these costs are structural, not cyclical.
• Understanding your specific council's expenditure breakdown — particularly the split between social care and other services — gives you a clearer picture of why visible local services are struggling even as bills rise.
• Section 114 councils face above-cap increases and severe service cuts, making local authority financial health a material factor for residents considering where to live or invest in property.

Council tax reform is overdue. The valuation problem is well understood. The care funding mismatch is increasingly well evidenced. What has been missing is the political will to tackle a tax that touches every household and a care system whose costs are politically sensitive. Until that changes, expect your council tax bill to keep rising — and expect the services it notionally pays for to keep disappointing.

Frequently Asked Questions

Why does council tax vary so much between areas?

Council tax varies because it is set locally by each council based on their Band D rate, which in turn reflects their funding needs and the revenue they raise from other sources like business rates and government grants. Wealthier areas with strong commercial economies generate more business rates income, reducing their reliance on council tax. Meanwhile, the demographics of an area — particularly the proportion of residents requiring social care — significantly affect how much councils need to raise. Property valuations, which have not been updated since 1991 in England and Scotland, also mean the relationship between property values and council tax paid is highly inconsistent.

What is a Section 114 notice and what happens when a council issues one?

A Section 114 notice is a formal declaration by a council's Chief Finance Officer that the authority cannot balance its budget — the local government equivalent of insolvency. Councils cannot technically go bankrupt or shut down, but once a Section 114 is issued, all non-essential spending must cease immediately. Government commissioners are typically appointed to oversee finances, and the council usually seeks special permission to raise council tax above the standard cap to help address the deficit. Residents typically face both significant service cuts and above-average bill increases as a result.

How is council tax calculated and what are the bands based on?

Council tax is divided into bands A to H (plus band I in Wales), based on estimated property values as of April 1991 in England and Scotland, or 2003 in Wales. Band D is the reference point: each council sets its Band D rate, and all other bands are calculated as fixed legal percentages of that figure. Properties built after 1991 are assigned a band by the Valuation Office Agency using comparative valuation — estimating what the property would have been worth in 1991. The system has not been fundamentally reformed since its introduction and does not reflect the substantial changes in UK property values since then.

Why are local services declining even as council tax bills rise?

The primary reason is that a growing proportion of council budgets — currently around 65% of non-education spending in England according to IFS estimates — is consumed by adult social care and children's services. These are statutory obligations under the Care Act 2014, meaning councils are legally required to fund them regardless of budget pressure. As demand for care rises with an ageing population and more complex needs, and as costs in children's residential care have risen sharply due to private equity dominance in the sector, less money is left for the visible services residents associate with their council tax bill. Rising homelessness costs add further pressure. Even councils receiving more funding can find that all of the additional income and more is absorbed by statutory care commitments before it reaches libraries, parks, or road maintenance.

Should social care be funded nationally rather than through council tax?

A growing number of economists and policy analysts argue that social care should be funded nationally — much like the NHS — rather than falling primarily on local councils. The case rests on the fact that care demand varies significantly by local demographics in ways that are outside councils' control, and that poorer areas with higher care needs are least able to fund those needs from local taxation. Funding care locally risks trapping deprived areas in a cycle where high care costs crowd out investment in economic regeneration, which in turn reduces future tax revenues and increases future care demand. Nationally funding and guaranteeing care while managing it locally could reduce this structural inequality, though it would require significant central government expenditure and political commitment to reform.
