Best Council Tax Reduction Guide for Somerset Households with Non-Dependant Adults
If you live in Somerset and have adult children, elderly relatives, or other adults in your household, you already know the problem: Somerset Council deducts a flat £10.00 per week from your Council Tax Reduction award for each non-dependant adult living at home. That's £520 per year, per person — and it comes off your award after the percentage discount is calculated, so even a 100% CTR household can end up paying hundreds. Check how Somerset classifies each resident before assuming that a particular status removes the deduction.
How the £10 Weekly Deduction Works
Since April 2025, Somerset operates a flat non-dependant deduction: £10.00 per week for every non-dependant adult in the household. A non-dependant is broadly any adult (18+) living in your home who isn't your partner and isn't a dependent child you receive Child Benefit for. The most common are adult children who've finished education, elderly parents, and adult siblings.
The deduction applies regardless of the non-dependant's income. A son earning £40,000 a year and a daughter on Universal Credit both trigger the same £10 weekly deduction. This is a significant change from many other councils, which grade the deduction by the non-dependant's income.
The maths can be brutal. A single disabled person on ESA in a Band C property might qualify for 100% CTR (£26.25 per week after single person discount). One non-dependant adult son at home reduces that to £16.25. Two non-dependant adults reduce it to £6.25. Three wipe out the award entirely.
Check Who Counts as a Non-Dependant
A full-time student's home address can still count for residence even when they're away during university term. Do not assume student status removes the deduction. PIP, DLA, or Carer's Allowance status also does not by itself establish that the deduction is removed. Ask Somerset Council to confirm whether the person counts as a non-dependant and whether an exception applies before estimating your award.

Real Impact: Three Households
Household 1: Parent with working adult son; no exception is assumed. Single parent in Band B, earning £90 per week, assessable income after disregards = £65. Band 1 = 100% discount. Weekly CTR award = £22.50 (after single person discount). Non-dependant deduction = £10. Net award = £12.50. Annual bill = £520 instead of £0.
Household 2: Parent with adult son on PIP. Same single parent, same income, same 100% Band 1 award of £22.50/week before any non-dependant deduction. The son's PIP status does not establish that the separate £10 deduction is removed. Confirm his non-dependant status with Somerset Council before assuming the full £22.50 award.
Household 3: Parent with two adult children — one student, one working. Same parent, same award. A student's home address can still count for residence during university term, so do not assume the student is exempt. If Somerset counts both children as non-dependants, the combined deduction is £20 and the net award is £2.50. Confirm how the council treats each person.
Checking how the council classifies each resident can make a difference of hundreds of pounds a year.
Who This Is For
- Somerset households with adult children (18+) living at home who are claiming or plan to claim Council Tax Reduction
- Parents whose CTR award has been reduced by non-dependant deductions and want to check whether the household has been classified correctly
- Households where a resident receives PIP, DLA, or Carer's Allowance and wants to confirm how Somerset treats the deduction
- Family members or carers helping someone navigate a complex household claim
- Anyone confused by the interaction between non-dependant deductions and the Band D property cap
Who This Is NOT For
- Households where all adults are partners or dependent children — non-dependant deductions don't apply
- Pension-age residents — the national scheme has different (income-graded) non-dependant deduction rules
- Single-person households — if you live alone, there are no non-dependants to trigger deductions
- Residents of North Somerset or Bath & North East Somerset — different councils, different deduction structures

Frequently Asked Questions
Does my adult child trigger a non-dependant deduction even if they don't pay rent?
Yes. The deduction is based on presence in the household, not on whether the non-dependant contributes financially. Somerset applies a flat £10 per week per non-dependant adult regardless of their income or whether they pay you anything. If you think an exception applies or the council has misclassified someone, ask Somerset to review the decision.
My son is at university but his address is registered here. Does the deduction still apply?
Not necessarily. A student's home address can still count for residence even when they're away during term time, so do not assume full-time student status removes the £10 deduction. Ask Somerset Council to confirm how it treats your son's circumstances and provide any evidence the council requests.
Can I ask the council to remove a non-dependant deduction that was applied incorrectly?
Yes. If you think the council has counted someone incorrectly, contact Somerset Council with details of the household and liability. If you dispute its decision, send a written grievance to the council under Section 16 of the Local Government Finance Act 1992. If the council rejects it, appeal to the Valuation Tribunal for England within two months of its written response. If it does not respond within two months, you have four months from the date you submitted the grievance to appeal.
The £10 deduction wipes out most of my CTR. Is there any other help?
If the non-dependant deduction leaves you in hardship, you may be eligible for Somerset's Exceptional Hardship Scheme (EHS) — a discretionary top-up under Section 13A. You'll need to show that even with the reduced CTR, you can't meet your essential living costs. The application requires two months of bank statements and a full income-and-expenditure breakdown.
