Tender prices on the Isle of Man are estimated to have increased by around 35% since 2020, driven by rising transport costs, wage pressures and growing uncertainty in the construction market.
BCIS data shows All‑In Tender Price Inflation up 23.5% UK‑wide over the same period, with the island’s higher location factor amplifying the impact.
AtkinsRéalis’ forecast for 2026 to 2030, prepared after the onset of the Middle East conflict, suggests the island will face greater construction inflation than the UK.
Contractors report that delays to projects now force them to include larger contingencies or contractual protections to manage volatile material prices.
A further concern is the island’s exposure to fuel costs. When fuel prices rise, transportation costs increase across both road and sea freight, and the impact on logistics is felt more acutely on the Isle of Man than in most parts of the UK.
This feeds directly into tender pricing, particularly for projects reliant on imported materials.
Material supply remains a structural challenge. Aside from limited aggregates and concrete blocks, the Island relies almost entirely on imports.
With no local competition and irregular project pipelines, suppliers struggle to secure discounts. Annual transport cost increases must be factored into tenders, meaning delays push costs higher.
