Inflation happens when prices rise over time. For example, if inflation hits 3%, a £100 item today would cost £103 next year. That means your money doesn't stretch as far as it used to. In the UK, inflation was about 3% in January 2026, down from a peak of 11.1% in October 2022, but still above the Bank of England's 2% target. Here, we'll break down inflation, why it matters to your money, and some ways to guard against it.
What is Inflation?
Prices going up over time is what we call inflation. Think about buying your regular loaf of bread and noticing it costs more than it did last year. That’s inflation in action. When prices rise by a certain percentage, your money can buy less than before. For example, with 3% inflation, £100 today would buy what £103 buys a year from now.
The UK has two main ways to measure inflation. The most official one is the Consumer Price Index, or CPI. It looks at prices for a basket of goods and services that people typically buy. The Bank of England aims to keep CPI inflation at about 2% to keep the economy healthy.
There’s also the Retail Price Index (RPI), which includes extra costs like mortgage interest payments. RPI usually shows a higher inflation rate but isn’t used for official targets anymore.
How Does Inflation Work?
Inflation happens for a few reasons.
One is demand-pull inflation — that’s when people want to buy more than what’s available, so sellers raise prices. Another is cost-push inflation, where the costs of making goods go up. For example, if oil prices rise, it costs more to produce and transport things, so prices climb.
Monetary inflation happens when the economy gets flooded with too much money, which lowers the value of each pound. During the COVID-19 pandemic, the UK’s government and Bank of England used quantitative easing (QE) — a form of money printing — to support the economy, which contributed to inflation later.
In early 2026, UK inflation was around 3% according to CPI, quite a drop from the 11.1% peak in October 2022 but still above the 2% target. The rise and fall have been influenced by factors like the Middle East conflict pushing oil prices up, food prices stabilising, and services inflation staying sticky. Meanwhile, wages have been growing around 5-6%, which is good news but still a tricky balance.
Why Does Inflation Matter to Your Money?
Inflation impacts your money in a few key ways. First, it erodes the value of your savings. If you keep cash in a basic savings account that pays less interest than inflation, your money loses buying power over time.
Inflation also influences mortgage rates. The Bank of England adjusts its base interest rate to manage inflation. As of early 2026, the base rate was 3.75%. When inflation is high, the Bank raises rates to make borrowing more expensive. This tends to slow spending and bring prices down. But it also means higher mortgage payments for many homeowners.
Wages are another piece. If your pay rises slower than inflation, you effectively earn less — a pay cut in real terms. For benefits, the government usually adjusts payments based on the previous September’s CPI to help keep up with rising costs.
How Does the Bank of England Control Inflation?
The Bank of England uses the base interest rate as its main tool. Raising the base rate makes borrowing more expensive, so people and businesses spend less. This helps cool down the economy and reduce inflation.
But there’s a trade-off. Higher interest rates mean higher mortgage payments and borrowing costs. For example, at a 3.75% base rate, many mortgage holders see increased monthly costs compared to lower rates in previous years.
The Bank targets 2% CPI inflation to keep the economy stable. If inflation stays above that for too long, it risks eroding people's purchasing power and causing economic uncertainty.
How to Protect Yourself from Inflation
Because inflation eats away at cash value, it’s smart to avoid keeping too much in basic savings accounts unless their interest beats inflation. Instead, consider investing in assets that tend to grow faster than inflation, like stocks or property.
Individual Savings Accounts (ISAs) are a popular UK option. They let you invest or save without paying tax on the returns, which can help your money grow more effectively.
Locking in fixed-rate savings or mortgages can also shield you from rising interest rates. When you fix a mortgage rate, your payments stay the same even if the Bank of England raises rates.
Lastly, keep an eye on your wage growth compared to inflation. If pay rises aren’t keeping up, it might be worth discussing this with your employer or seeking ways to supplement your income.
Common Questions About Inflation
Q: What’s the difference between CPI and RPI?
CPI measures prices of goods and services people buy. RPI includes housing costs like mortgage interest. CPI is the official measure the UK government uses for inflation targeting.
Q: Why is inflation still above the 2% target?
Several factors keep inflation above 2%, like higher oil prices due to global conflicts, sticky prices in services, and ongoing wage growth.
Q: How often does the Bank of England change interest rates?
The Bank usually reviews rates eight times a year but can act more or less often depending on economic conditions.
Q: Is 3% inflation bad?
Not necessarily. The Bank of England aims for 2%, but inflation around 3% is still manageable and better than the double-digit rates seen in 2022.
Q: Should I keep cash or invest it?
Holding some cash is sensible for emergencies, but to protect your money’s value, investing in assets that outpace inflation is usually recommended.
Inflation is a steady rise in prices that affects how far your money goes. In the UK, inflation has eased from its recent highs but remains above the Bank of England’s 2% target as of early 2026. Understanding inflation helps you see why your savings might buy less, why mortgage rates change, and how wages relate to your cost of living. By choosing the right savings and investment strategies—like ISAs or fixed-rate mortgages—you can help protect your money against inflation’s squeeze.
