What Slower UK GDP Growth Means for Your Mortgage Rate

UK GDP growth slowed to 0.4% between April and June, the Office for National Statistics said on Thursday, down from 0.6% in the first three months of the year. By recent British standards that is a respectable number. It is also, awkwardly for anyone remortgaging this autumn, the kind of number that makes a rate cut less likely rather than more.

The monthly pattern is stranger than the headline suggests. April shrank by 0.1%. May was completely flat, revised down from a first reading of 0.1%. Then June grew 0.3%, comfortably beating the zero that economists had pencilled in. Almost all of the quarter's momentum arrived in the last four weeks, after a spring disrupted by conflict in the Gulf and the shipping squeeze around the Strait of Hormuz.

That mix matters for your money. Bank Rate sits at 3.75%. Three of the nine members of the Bank of England's Monetary Policy Committee voted at the end of July to push it up to 4.00%. An economy that keeps expanding while inflation climbs is precisely the backdrop that argues for holding rates steady, or raising them — not cutting.

Where UK GDP Growth Actually Came From

Services did nearly all the lifting, up 0.5% across the quarter — banking, insurance, hotels and restaurants among them. Construction added 0.3%. Production, the part of the economy that physically makes things, did not grow at all. Factories standing still while the service sector carries the country is a familiar British pattern, but it is not a healthy one to rely on.

Firms told the ONS that good weather and a packed summer of sport helped trade. Household spending rose 0.3% and business investment jumped 1.7%, the brightest line in the whole release and a sign companies have not frozen despite the geopolitical noise. Measured against a year earlier, the economy is 1.2% bigger, marginally ahead of the 1.1% forecasters had expected.

"Growth slowed in the second quarter of the year, but remained relatively robust," said Liz McKeown, a director at the ONS.

Why Rate-Setters Are Talking Rises, Not Cuts

Markets barely twitched at the release — sterling moved a hundredth of a percent against the dollar, hovering near $1.3495. That flatness tells you something. Traders had already priced this in, and their attention has moved to what the Bank does next.

The July Vote Split 6-3 the Wrong Way

On 30 July the committee left Bank Rate at 3.75%. Six members wanted to hold; three wanted an immediate quarter-point rise. For most of the past two years the dissenting votes pushed for cheaper money. This time they pushed the other way, and a quarter of 0.4% growth gives them nothing to retreat from.

Inflation Is Forecast to Peak Above 3%

Consumer price inflation was 2.6% in June. The Bank's own July projection now has it peaking at roughly 3.2% in the final quarter of this year, largely on energy costs following the Gulf disruption. That is more than a full point above target. Central banks almost never cut into a rising inflation path unless activity is falling apart — and it clearly is not.

The Date to Put in Your Diary Is 17 September

The next rate decision lands on Thursday 17 September. Between now and then come July's inflation reading and fresh labour market figures. If price growth accelerates towards the Bank's 3.2% peak while output holds up, the three hawks may find they have company.

What This Does to Your Mortgage and Savings

The practical read is that the cheap-money reversal many households were banking on has been pushed further out. If you assumed a fix taken in 2021 could be replaced at a similar rate, that assumption needs updating. A few things worth doing now rather than in October:

• Check your fix's end date. Most lenders let you lock a new deal up to six months ahead and switch free if rates fall.
• If you are on a tracker or standard variable rate, price a fix — the market is no longer leaning towards cuts.
• Move idle cash. Easy-access savings above 3.75% are still available and beat June's 2.6% inflation, but many high-street accounts do not.

The Figure Politicians Will Argue About

Chancellor John Healey pointed to the UK posting the fastest growth in the G7 this year and said the government would double down and drive growth in every postcode. Fair enough on the comparison. But GDP per head — the measure closest to whether individuals feel better off — rose just 0.4% in the quarter and 1.0% over the year. Cash GDP grew 4.1% annually against real growth of 1.2%, which is another way of saying most of the increase is prices, not output.

How Much Should You Trust a First Estimate?

Not entirely. This is a first cut, built from partial survey returns, and the ONS publishes its own track record: first estimates have historically been revised up by an average of 0.08 percentage points, with an average revision of 0.27 points in either direction. On that history, 0.4% could plausibly end up as 0.1% or 0.7%. No earlier quarters were revised this time, which is at least a small mark of stability.

The number to watch is not the next GDP print but July's inflation figure, due before the September meeting. If it comes in near 3%, borrowers should plan for rates staying at 3.75% into 2027 and stop waiting for a cut that keeps receding. Lock what you can, and treat any fall in mortgage pricing this autumn as a bonus rather than a plan.
