UK Inflation Rises to 3.5%: What It Means for Your Money
Prices are rising faster again. New figures show UK inflation jumped to 3.5% in September 2026 – and if you're saving, investing or living on a pension, it's worth a few minutes to see what that means for you.
Here's what changed, who it affects and what you may want to review. No panic, no predictions – just the facts.
Remember: investing puts your capital at risk. The value of investments can fall as well as rise and you may not get back the amount originally invested.
First, The Basics: What The New Figures Say
Inflation (CPI) rose to 3.5% in the 12 months to September 2026, up from 3.1% in August (ONS: Consumer price inflation, UK: September 2026, published 21 October 2026).
Transport, particularly motor fuels, made the largest upward contribution, according to the ONS.
CPIH, the ONS's wider measure that includes owner occupiers' housing costs, rose to 3.6%.
Bank Rate is 3.75%. The Bank of England held it at that level on 17 September 2026, and its next decision is due on 5 November 2026 (Bank of England: Bank Rate). The Bank's target for inflation is 2%.
In plain English: on average, the things we buy cost 3.5% more than a year ago. If your money is growing by less than that, its spending power is shrinking.
1. Cash Savings: Check Your Real Return
Cash has an important job. It's your emergency fund and money you'll need soon. But when inflation is higher than the interest you earn, the real value of your savings falls.
Compare your rate with inflation: an account paying less than 3.5% is currently losing ground in real terms.
Watch the tax on interest: for the 2026/27 tax year, the Personal Savings Allowance lets basic-rate taxpayers earn up to £1,000 of interest without paying tax on it, higher-rate taxpayers £500 and additional-rate taxpayers nothing (gov.uk: Tax on savings interest).
Use your ISA allowance: you can save up to £20,000 across your ISAs in the 2026/27 tax year, and interest and returns inside an ISA are normally free of UK tax (gov.uk: Individual Savings Accounts).
Rates can change at any time, and inflation risk applies to cash too. Holding too much in cash for too long has its own cost.
2. Investments And Pensions: Stay Focused On The Long Term
Investments such as shares can grow faster than cash over the long term, but that isn't certain. Their value can fall sharply, and past performance is not a reliable guide to the future.
Don't react to one month's figures: a single inflation reading is a reason to review, not a reason to rush.
Check your mix: the right balance between cash, bonds and shares depends on your goals, your timescale and how much risk you can take.
Think about your income: if you're drawing from a pension, higher prices may mean you need more income – and taking more can make your pot run out sooner.
3. Retirement Income: Look At The Bigger Picture
If you're retired or close to it, inflation matters a lot. Your income needs to keep up for what could be 25 years or more.
Some income rises with inflation, some doesn't: check which of your pensions and annuities increase each year, and by how much.

Case Study: Jennifer's Review (Illustrative)
Names and details are illustrative.
Jennifer, 63, from Chester, kept most of her savings in an easy-access account "just in case". When she compared her rate with inflation, she realised her money was losing value in real terms each year.
With an Independent Financial Adviser (IFA), she agreed how much she needed in cash for emergencies and planned spending. She then reviewed the rest against her goals and attitude to risk, and made sure she was using her ISA allowance.
Key lessons:
Know your real return: interest minus inflation is what really matters.
Cash has a role, but a limited one: keep enough for emergencies and short-term needs.
Risk and reward go together: moving beyond cash means accepting that values can go down as well as up.
