Persimmon forward sales up 7%, but builder flags supply chain inflation risk from Iran conflict

Persimmon PLC (LSE:PSN), the FTSE 100 housebuilder, has warned of emerging supply chain inflation driven by the ongoing conflict in Iran, cautioning that higher energy costs are likely to weigh on second-half margins even as the group reported a solid start to 2026. In a trading update, the York-based group said there are early signs of increased inflationary pressure in its supply chain, which it attributed to higher energy costs linked to geopolitical uncertainty, with the impact expected to be felt in the second half of 2026 and into 2027.
