Your council tax bill arrives every spring with a headline number and a breakdown most of us skim. The figure you pay depends on two things that have almost nothing to do with each other: what your home was worth on a single day in 1991, and what your borough and City Hall decided to spend this year. Understanding both makes the bill easier to argue with — and there is more room to argue than most people assume.
How a London council tax band is set
Every home in England sits in one of eight bands, A to H. The band is decided by the Valuation Office Agency (VOA) and reflects the property's estimated value on 1 April 1991 — not what you paid for it, and not what it would sell for now. Bands have never been updated, which is why a converted warehouse in Hackney and a 1930s semi in Bexley can land in unexpectedly similar territory.
Band D is the benchmark. Councils quote a "band D" figure because it makes boroughs comparable, and every other band is a fixed fraction of it:
- Band A — 6/9 of band D
- Band B — 7/9
- Band C — 8/9
- Band D — 9/9, the reference point
- Band E — 11/9
- Band F — 13/9
- Band G — 15/9
- Band H — 18/9
In other words, a band H household pays twice what a band D household pays, while a band A household pays two-thirds. If your bill mentions a band D figure, that is context for comparison, not your charge.
The City of London runs its own separate arrangement, and residents there should not assume the borough model applies. Everyone else — all 32 boroughs — follows the eight-band system.
The two parts of a London bill
Open your bill and you will usually see two distinct charges, even though they arrive as one payment.
The borough element
This is the larger share, typically around three-quarters of the total. It is set by your council at its annual budget meeting and pays for the services it is legally responsible for: adult and children's social care, waste collection, road maintenance, libraries, parks, planning, environmental health, homelessness support and council housing. Social care is the heaviest pressure in most boroughs — often the single biggest slice of the budget, and the reason many councils say they have little discretion left.
One common misconception: your council tax does not fund your local school in any direct way. Schools are largely paid for through separate government grants, so a rise in your bill is not automatically heading to the primary down the road.
The GLA precept
The second charge comes from the Mayor of London, agreed with the London Assembly. It funds the Metropolitan Police, the London Fire Brigade, Transport for London and other City Hall functions, and it is collected by your borough on the Mayor's behalf. On most bills it is itemised separately — sometimes as a policing element and a general element — and it is the same amount across every borough, which is why two neighbouring councils with similar services can still produce different totals.
What you are actually buying
Council tax covers only part of what councils spend; the rest comes from business rates, government grants, fees and reserves. Set against that, here is where the money broadly goes:
- Social care — support for older and disabled residents, children in care, safeguarding teams.
- Waste and streets — refuse collection, recycling, street cleaning, fly-tipping enforcement.
- Housing — homelessness prevention, temporary accommodation, council housing management.
- Highways and traffic — potholes, street lighting, parking enforcement, road safety schemes.
- Culture and leisure — libraries, parks, sports centres (often run through trusts or contractors).
- Regulation — planning, licensing, environmental health, trading standards.
- Policing, fire and transport — through the GLA precept rather than your borough.
How to check your band and challenge it
You cannot appeal simply because the bill feels too high. But you can challenge the band itself if you believe it is wrong, and neighbours in similar properties are your best evidence.
- Look up your band on the government's VOA service, and note the band of every similar home on your street.
- Gather evidence of what your property would have been worth in 1991 — comparable sales from that era, or the bands of genuinely similar houses nearby.
- Raise it informally with the VOA first. Many corrections happen at this stage without a formal case.
- Make a formal proposal if that fails, and be aware of time limits — commonly six months from when you became responsible for the bill, or whenever there has been a material change such as demolition, a new road scheme or a property split.
- Escalate to the Valuation Tribunal for England if the VOA turns you down. It is independent and free to use.
Keep paying your bill while a challenge is running. Only the disputed amount can be held back, and even then only with the council's agreement. If your issue is about liability, a discount or an exemption rather than the band, that is a separate route: council first, then its complaints process, then the Local Government and Social Care Ombudsman. For anything involving probate, a landlord dispute or a large arrears balance, a free session with Citizens Advice or a local law centre is worth the phone call before you sign up to a payment plan.
Discounts most people forget to claim
Bands are only half the story. The other half is whether you should be paying the full charge at all.
- Single person discount — 25% off if you are the only adult in the property.
- Disregarded adults — full-time students, apprentices, some carers and people with a severe mental impairment do not count towards the household total.
- All-student households — usually exempt entirely.
- Care leavers — many boroughs offer relief, though the age limits vary, so ask yours directly.
- Disabled band reduction — if a resident needs extra space for equipment or a wheelchair, you can be billed at the band below.
- Council tax support — every London borough runs a local scheme for lower-income households. It is not automatic; you have to apply.
Remember the reverse also applies: empty homes and second homes can attract a premium in many boroughs, and you must tell your council within 21 days of any change that affects your entitlement.
What to expect for 2026-27
Next year's figures will be confirmed in February and March 2026, when boroughs vote through their budgets and the Mayor publishes the GLA precept. The government sets a referendum threshold each year, and any borough proposing an increase above it must put the question to voters — which is why most increases cluster just beneath the limit rather than at it. Watch your council's budget meeting coverage, not the bill that follows.
Three things to do this month
First, check your band and your neighbours' bands on the VOA service — it takes ten minutes and costs nothing. Second, confirm you are receiving every discount you are entitled to, particularly if someone has moved in or out recently. Third, call your council's revenues team about spreading payments over 12 months instead of the default ten, choosing your direct debit date, and applying for council tax support if your income has changed. The bill may be fixed by formula, but how and when you pay it is often yours to decide.
