Council tax in Southwark isn’t just a line on a bill — it’s one of the highest fixed costs for households in SE1, SE5, SE15, SE16 and across the borough.
For 2026/27, residents in the London Borough of Southwark are facing a 4.99% increase (2.99% core + 2% Adult Social Care precept). The estimated Band D total is £1,967, including the Mayor’s Greater London Authority (GLA) charge.
But here’s what most guides don’t explain clearly:
- Nearly £490+ of your bill goes to the GLA, not Southwark Council
- Empty homes now face a 100% premium after 12 months
- Council Tax Reduction rules changed for households with adult children
- Southwark offers niche local discounts that many residents never claim
This guide breaks it all down — with practical examples from Elephant Park, Aylesbury Estate regeneration, and everyday MySouthwark portal use.

Why Is Southwark Council Tax So High?
This is one of the most searched questions.
The simple answer: it’s not all going to Southwark Council.
Band D Breakdown (Approximate)
- ~£1,470 → Southwark Council services
- £490+ → Greater London Authority
- Included: 2% Adult Social Care precept
The GLA portion funds London-wide services under the Greater London Authority — including policing and fire services.
So when residents say “Southwark is expensive,” they’re often reacting to London-wide costs layered into the bill.
Technical Billing Formula (Authority Breakdown)
Total Bill=(Band Multiplier×Band D Rate)+GLA Precept\textbf{Total Bill} = (\text{Band Multiplier} \times \text{Band D Rate}) + \text{GLA Precept}
Where:
- Band D = base reference rate
- Other bands = percentage of Band D
- GLA charge = flat addition across bands
This clarity helps residents understand the increases year-to-year.
The 2026 Empty Property Premium (Major Rule)
This is one of the biggest changes affecting landlords and second-home owners.
If your property is:
- Empty and unfurnished
- Not your main residence
- Vacant for 12 months or more
You may now face a 100% council tax premium.
What That Means:
Band D property (£1,967)
→ After 12 months empty
→ £3,934 per year
This has impacted investors in Elephant Park and probate properties across Camberwell.
If you’re between tenants, plan carefully.
Council Tax Reduction (CTR) 2026 Changes
Southwark’s Council Tax Reduction scheme helps low-income households — but 2026 adjustments matter.
Key Update:
Non-dependant deductions have been updated.
If an adult child (over 18) lives with you and works, your reduction may decrease.
This has affected multi-generational households in Peckham and Walworth, especially.
If your circumstances changed, recalculate — don’t assume your old discount still applies.
The Southwark Discount Checklist
Many residents qualify for help but never apply.
You May Be Eligible For:
✔ 25% Single Person Discount
✔ Full-time student exemption
✔ Severe Mental Impairment (SMI) exemption (100%)
✔ Care Leaver Relief (100% discount up to age 25)
✔ Registered Southwark foster carer reduction
✔ Disability band reduction scheme
✔ Council Tax Reduction (low income)
Under-claimed Benefit:
The Severe Mental Impairment exemption remains significantly underclaimed in SE1 and SE16.
Real Local Example: Regeneration Banding Issues
During redevelopment in the Aylesbury Estate area, some flats were initially banded higher following refurbishment assessments.
Residents compared similar nearby properties and successfully challenged valuations.
Lesson: Regeneration zones often contain inconsistent banding.
Always compare like-for-like properties on your street.
