EU vs UK carbon price (2026)

Two systems separated at Brexit: EU ETS ≈€77.4, UK ETS ≈£55. A linkage deal was announced in 2025 — here's what converging prices mean.

	EU ETS	UK ETS
Price	€77.4 (11 Jun 2026)	≈£55 (mid-2025, ICE)

Border measure	CBAM live since 2026	UK CBAM planned 2027
Linkage	announced 2025 — UK price expected to converge upward toward the EUA

What linkage means for UK industry

Linked markets trade one effective price. UKAs have historically traded £10-20 below EUAs; convergence implies a step-up in UK carbon costs toward €77.4-level. UK plants get EU-CBAM relief in exchange (no border charge on UK exports to the EU). Net effect: the cheap-carbon window for UK industry is closing — efficiency investments made before convergence are bought at a discount.

Inzonex removable modular insulation on industrial equipment

Cut the tonnes at the source

Hot industrial equipment? Cut the heat loss.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:

Up to 90% less heat loss from insulated surfaces
Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
6× faster maintenance access than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
Typical payback under 2 years (some 9–11 months)

FAQ

Questions on this topic

Why is the UK carbon price lower than the EU's?

A smaller, less liquid market with its own supply settings; UKA has mostly traded at a discount to EUA since 2021.

Will UK and EU prices become one?

The 2025 announcement targets linking the two ETS — once live, allowances become fungible and prices converge. Most analysts expect the UK price to move up toward the EUA, not vice versa.

Does UK CBAM copy the EU's?

Same idea — a border carbon price on iron & steel, aluminium, cement, fertilizers, hydrogen — planned from 2027, with design details (tax-style rather than certificates) still being finalised.
