ONS GDP Data: UK Economy Beats Forecasts as New Housing Work Falls Again

The economy grew faster than expected in July, but the construction detail beneath the headline number tells a more divided story — one with direct implications for both sides of the property finance market.

The Headline Number: Growth Ahead of Expectations

ONS data published on 11 September 2026 showed UK GDP grew 0.4% in July, ahead of the 0% growth economists had forecast and accelerating from 0.3% in June and no growth in May. On an annual basis, GDP was 1.6% higher than a year earlier, beating consensus expectations of 1.2%. Over the three months to July, GDP grew 0.4% against the three months to April — the eighth consecutive three-month period of expansion, even as momentum has clearly slowed from earlier in the year.

Markets responded immediately: sterling rose against both the dollar and the euro, and gilt yields fell.

Construction: Repair and Maintenance Up, New Work Down Again

Services did the heavy lifting. Output rose 0.4% in July and 0.6% over the three months to July, and remains the main driver of the recovery. Production and construction were more mixed — both grew modestly in the month (0.2% and 0.1% respectively) but each contracted 0.5% over the three-month period.

The construction detail is the part that matters most for property investors. ONS’s companion construction output release, also covering July, shows total construction output down 0.5% over the three months to July — the first such fall after four consecutive three-month increases, including strong growth of 1.3% and 1.5% in the three months to April and May. Over that three-month window, both new work and repair and maintenance fell, by 0.4% and 0.7% respectively, with six of nine sectors in decline.

The monthly figure inverts part of that picture, but not evenly. July’s 0.1% monthly rise in construction output came entirely from repair and maintenance, up 0.8% in the month — driven by private housing repair and maintenance, up 1.7%. New work fell 0.4% in the month, with the largest single drag being a 4.9% fall in private housing new work.

Read together: on both the monthly and three-monthly view, refurbishment activity is holding up materially better than new-build. Annually, the split is starker still — over the three months to July, construction output was down 2.3% year-on-year even as services rose 1.7% and production 0.5%.

SME Development: Selectivity, Not Retreat

For SME developers, the data reinforces a pattern rather than announcing a new one. A 4.9% monthly fall in private housing new work, against rising repair and maintenance activity, is consistent with developers continuing to bring forward the schemes they have confidence in — refurbishment and repositioning of existing stock — while remaining more selective about new-build starts. Capital availability is not the constraint here; the pattern in the data is about which schemes are being brought forward, not whether finance exists to fund them.

BTL Landlords: The Swap Curve Is the Bigger Story

Gilt yields fell on the day, but gilts are not what fixed-rate mortgage and bridging products are priced against — swaps are. And the swap curve has moved in the opposite direction to today’s gilt reaction for months. Five-year swaps have risen from lows near 3.5% in February 2026 to a level closer to home breaching 4.6% by mid-September, on a mix of factors: the conflict in the Middle East, uncertainty in the US around record debt issuance, and record corporate bond supply. Set against that move, a single-day gilt dip on the back of a GDP beat is immaterial to the pricing landlords will actually see on new fixed-rate lending. The GDP print itself is a secondary factor in the rate environment landlords face; the swap curve is the primary one.

Capital Providers: Where the Structural Demand Sits, and What It Costs to Meet It

For those funding this activity rather than borrowing to do it, today’s release adds to a now well-established pattern: demand for short-term, refurbishment-oriented secured lending continues to outperform the new-build development finance market. With new work contracting again in July — most sharply in private housing — while repair and maintenance activity grows, the underlying flow of transactions requiring bridging and refurbishment finance shows no sign of slowing, even as the broader construction sector posts its first three-month contraction in over a year.

That demand is meeting a higher cost of funds than the GDP release alone would suggest. With five-year swaps closer to 4.6% than they have been since well before this GDP print, the reference rate for pricing secured lending has moved materially higher over 2026 — independent of, and larger than, today’s growth data. Any read of the lending backdrop that stops at gilts and GDP without accounting for the swap move is incomplete.
