At a glance
The UK's April CPI rose to 3.8% in the ONS release, up from 3.3% and above 3.5% forecasts, complicating Bank of England rate cut plans.
Britain’s consumer prices index rose by 3.8% in the 12 months to April 2026, the Office for National Statistics said on 20 May, up from 3.3% in March and above the 3.5% economists had expected. The core rate, which strips out energy, food, alcohol and tobacco, rose to 3.9% from 3.6%. Services inflation hit 5.1%.
The Bank of England has spent the first half of 2026 waiting for services prices to cool. They did not. Instead the April figures landed at a moment when markets were already split over the next rate move, and the result was immediate: gilt yields rose, two-year mortgage swap rates ticked higher, traders pushed back their timing for the next cut, and the pound gave up its earlier gains.
A payroll administrator in Leeds is watching the repricing with a sense of déjà vu. Her fixed mortgage ends in October, and her energy direct debit rose in April under the new cap. Her planning assumed two further quarter-point Bank Rate cuts this year. That assumption now looks optimistic.
Inflation’s climb is broad enough to worry Threadneedle Street
The Office for National Statistics said electricity and gas prices made the largest single upward contribution. The default tariff cap took effect in April, and last year’s lower base made the annual comparison steeper than the monthly rise would suggest on its own.
Food prices also turned higher, while recreation, air fares, package holidays and restaurant margins pushed up the services measure. None of that is a one-off energy story. The ONS inflation and price indices show core inflation accelerating, which is the detail that central bankers least wanted to see.
| Measure | March 2026 | April 2026 |
|---|---|---|
| CPI, 12-month rate | 3.3% | 3.8% |
| Core CPI | 3.6% | 3.9% |
| CPIH | 3.5% | 3.9% |
| Services inflation | 4.8% | 5.1% |
The Leeds administrator’s lender sent a renewal illustration in early May. The two-year fix had risen by about 0.2 percentage points since mid-April, a small move that adds £38 a month to her projected payment.
The rate-cut path narrows
Bank Rate sits at 4.0%. Further easing was meant to depend on services inflation falling toward 4%; it has done the opposite. Before the April print, money markets priced two quarter-point cuts by December. By the close of trading, the first full cut was pushed to November and the second had dropped out of the year-end path.
The Bank of England’s Monetary Policy Committee now faces a sharper trade-off. A weak labour market argues for insurance cuts, but wage settlements near 4.5% and rising services prices argue for patience. April’s data strengthened the second group without settling the argument.
Our earlier May rate decision explainer laid out the committee’s divisions. The inflation release hardened those divisions rather than clearing them.
Households caught between two resets
For the payroll administrator, the inflation reading is a pair of monthly lines on a budget. Her energy direct debit rose by £19 a month in April. Her mortgage renewal projection rose by roughly £38 a month within a week of the CPI release. Neither cost is fixed until contracts reset, but both are moving away from her.
Wages remain the counterweight. Average weekly earnings growth excluding bonuses has held above consumer prices in recent months, which cushions the immediate squeeze. But the Bank of England wants pay settlements to slow because it cannot afford a new wage-price loop. Households are caught in that overlap: incomes are rising, yet the annual bills that reset are rising faster.
What the Bank watches next
The May consumer prices release and the next labour market report will now carry more weight than any speech. Analysts will be watching services inflation first, core goods second, the annual contribution from energy third, and the wage revisions as a cross-check. If services inflation stays above 5% through the summer, the next cut slides into 2027. If it falls back toward 4.5%, April may be remembered as an energy tariff-driven blip.
The Monetary Policy Committee will also update its quarterly projections in August. A higher inflation profile, combined with a slower easing path, would change the 2027 that households and businesses have been planning around since January.
The next ONS release arrives in mid-June. The Leeds administrator will read it the way the Bank does, not as a one-month verdict but as the first test of whether April was a step. Her remortgage date gives her less room for error than the committee has.
