Ibstock Cuts Output 20% as UK Brick Demand Slides 17%

UK brick market volumes fell 17% year-on-year in July and August, and Ibstock — Britain's biggest brickmaker — has responded by cutting planned production by a fifth. That's the sharpest signal yet that the housebuilding slowdown is entrenched, not a summer blip.

The numbers landed hard. Ibstock said third-quarter sales came in 22% below expectations, forcing the one-fifth production cut versus plans the company set out as recently as August. The shares dropped 11%, sliding to virtually their lowest level since the firm relisted on the stock market in 2015.

What does this change for earnings?

Plenty. Ibstock now expects top-line earnings for the whole of 2026 "in the mid-£40m range" — roughly £15m below the figure close to £60m the City had pencilled in. For a supplier of the most basic building material, that's not a rounding error; it's a downgraded view of the entire construction pipeline.

The pattern goes beyond one company. Housebuilders across the board have been issuing shareholder-friendly vows of "financial discipline" — corporate-speak for expansion being off the table and the job becoming about hammering away at costs. Berkeley Homes, focused on the south-east of England, said six months ago it will stop buying new land and hiring new staff. When builders stop buying land, brickmakers feel it first.

Why is demand stalling?

Two causes stand out. First, the turnaround in interest rate expectations tied to the Iran war. The Bank of England will probably raise rates this week, according to the source, and the open question is how many more increases follow. Second, housebuilders complain about regulatory costs that are hard to shed when new-house prices are moving sideways.

Then there's the waiting problem. Housing secretary John Healey's Your First Home scheme — the government's latest demand-side intervention — doesn't launch until next April, as the chancellor confirmed in his budget last week. The delay "may weigh on demand in the intervening period", Ibstock chief executive Joe Hudson said. He's surely right: for many qualifying buyers, waiting five months for discounted loans is simple arithmetic.

Is Your First Home a gamechanger?

Not as currently designed. Housebuilders welcome it — they had been lobbying for action for ages — but there are caveats:

• Caps on transaction sizes mean it isn't a Help to Buy copycat, deliberately so: Healey can't be seen adding inflationary pressure at this moment.
• The April launch date freezes demand in the meantime.

Healey also pledged no more changes to building regulations this parliament, except where critical for safety — a nod to the sector's other grumble. He is not, however, proposing to remove existing regulations, so that cost base stays put.

What's the realistic outlook?

Peel Hunt reckons Your First Home will be "modestly helpful", but "lower interest rates remain key to a pickup in sector activity". It all comes back to borrowing costs. The Office for Budget Responsibility forecasts just 1% economic growth in 2027, which is unlikely to move housebuilding volumes meaningfully.

The broader casualty is political. The government's ambition of 1.5 million new homes this parliament now looks out of reach — the target isn't officially rubble, but it may as well be. A couple of housebuilders report results later this week and can speak for themselves; on Ibstock's evidence, they'll be speaking carefully. The upturn, whenever it comes, looks too late to rescue the headline target.
