Sticky and Rising Again: Where UK Inflation and Interest Rates Stand Before a Pivotal Autumn

For much of the past two years, the story of the British economy has been a slow, grinding battle to bring inflation back under control. By 2026, many hoped that fight was more or less won. The latest figures, however, tell a more stubborn and slightly uncomfortable story.

With a fresh inflation reading and a Bank of England rate decision both due within days, this is a good moment to take stock. In this piece we set out exactly where UK inflation and interest rates stand right now, what is driving them and why the coming fortnight matters, using only the official published numbers.

Inflation ticks back up

Start with the headline figure. According to the official data, UK consumer price inflation stood at 2.9% in July 2026, up from 2.6% the month before. It is not a dramatic spike, but the direction of travel is the wrong one, moving away from the Bank of England's 2% target rather than towards it.

That matters because inflation had been widely expected to keep easing gently through the year. Instead, prices are proving sticky, a word that has become depressingly familiar to anyone watching the economy. When inflation stops falling and starts creeping up, it complicates every decision policymakers have to make.

Blame the energy bill

So what is pushing prices back up? The single largest upward contribution came from housing and household services, where inflation jumped to 4.1% from 2.7% in June. In other words, the cost of simply keeping a roof over your head and the lights on rose sharply between the two months.

The main culprit is energy. The figures reflect a 13% increase in Ofgem's energy price cap that took effect the previous month, feeding straight through to household bills. It is a stark reminder that, for all the talk of markets and central banks, inflation is often decided at the meter and the fuse box.

What the Bank expects

The Bank of England has not been blind to this. Based on energy market pricing in mid-June, it said it expected CPI inflation to be a little under 3% in the third quarter of 2026, before rising to a little over 3.25% in the final quarter. In short, the Bank itself anticipated this bump rather than being caught off guard.

That forecast is important context. It suggests the current uptick is broadly in line with expectations, not a sign that the situation is spiralling out of control. But it also means inflation is likely to sit above target for a while yet, which limits how quickly the Bank can afford to relax.

Rates on hold at 3.75%

All of this feeds directly into interest rates. The Bank of England base rate currently stands at 3.75%, a level designed to keep a lid on prices without choking off growth entirely. It is the fulcrum on which mortgages, savings and business borrowing across the country all balance.

The dilemma is a familiar one. Cut rates too soon and the Bank risks letting inflation take root again just as energy costs bite. Hold too long, and it squeezes households and businesses that are already stretched. With prices ticking up, the argument for patience rather than early cuts has clearly strengthened.

A pivotal fortnight

This is why the next couple of weeks carry real weight. The Office for National Statistics is due to publish its August inflation bulletin on 16 September 2026, and the Bank of England is set to announce its next rate decision the very next day, on 17 September.

Those two dates, back to back, will shape the mood heading into autumn. A hotter than expected inflation number could all but rule out rate cuts for months, while a softer reading might revive hopes of cheaper borrowing. Rarely do a data release and a policy decision line up quite so neatly, or so tensely.

What it means for you

Behind the percentages lie very real consequences. Sticky inflation and a base rate held at 3.75% point towards borrowing staying relatively expensive, which is unwelcome news for anyone remortgaging, but a modest silver lining for savers still enjoying higher returns than they saw for most of the last decade.

The bottom line is that the cost of living squeeze has not fully released its grip. Inflation is lower than at its frightening peak, but it is not yet beaten, and it is quietly rising again. For households and the Bank alike, the message of autumn 2026 is the same: stay alert, and do not assume the hard part is over.
