The European Union is preparing to make a British financial contribution a condition of any agreement to reconnect the UK to the bloc’s internal electricity market, according to EU documents and diplomats.
The position comes as Keir Starmer travelled to Brussels for meetings with the European Commission, European Counciland the European Parliament, amid a wider effort by London and Brussels to “reset” relations after Brexit.
EU member states want the UK to contribute to EU “cohesion” funding — the bloc’s term for programmes aimed at narrowing development gaps between richer and poorer regions — in exchange for renewed access to the electricity market. Diplomats briefed on the discussions said the approach is intended to align the UK’s position with the model used for non-EU participants that gain internal market access.
A draft negotiating stance cited by Reuters says the EU aims to “establish a permanent, legally binding mechanism” for an “appropriate financial contribution” by the UK towards reducing economic and social disparities across the Union. EU capitals are still debating the size of any payment and are expected to finalise a mandate for negotiations in the coming months.
The EU’s benchmark is Norway, which is not an EU member but has internal market access through the European Economic Area and contributes to cohesion through the EEA and Norway Grants. For the 2014–2021 funding period, Norway’s annual contribution was set at about €391 million.
For the UK, the issue is politically sensitive because one of the central claims of the 2016 Leave campaign was that Brexit would end mandatory payments to the EU budget. That sensitivity has sharpened as Reform UK, which frames closer alignment with Brussels as a threat to sovereignty, has risen in opinion polling.
The Labour Party government argues that closer energy cooperation would reduce costs and improve security of supply. A UK government spokesperson, asked about the emerging EU position, declined to comment on the talks but said that closer cooperation on electricity would benefit businesses and consumers by lowering costs, strengthening energy security and attracting investment in the North Sea.
Britain left the EU’s internal energy market when the Brexit transition period ended, and cross-Channel electricity trade has since operated without the market coupling arrangements used inside the EU. In practical terms, power trades across interconnectors linking Britain with EU states — including France and Denmark — are no longer automatically matched through a shared algorithm designed to use available capacity efficiently and direct flows to where power is most needed.
Industry groups and system operators have long argued that the change has imposed avoidable costs. National Grid told a parliamentary committee this month that the post-Brexit trading arrangement has added about £1 billion to UK–EU power trading so far, and that the additional cost could reach around £350 million a year by 2030. National Grid’s evidence to MPs emphasised that the inefficiency ultimately feeds through to consumer bills.
The renewed push for talks follows a formal UK–EU statement in December 2025 that both sides would work towards negotiating UK participation in the internal electricity market. The UK government has described 2026 as the year for starting those negotiations, alongside other parts of the wider “reset” agenda.
Energy cooperation is also being framed in Brussels as complementary to longer-term infrastructure and decarbonisation goals. Reuters reported that the two sides are pledging to deliver 100 gigawatts of offshore wind capacity through large-scale joint projects, which would require sustained coordination on networks, interconnectors and market design.
The immediate question is whether London will accept a standing contribution mechanism as the price of market integration — and, if so, how it will present that choice domestically. EU diplomats told Reuters that member states want a durable arrangement, rather than an ad hoc payment, to mirror existing internal market access models. For the UK, agreeing to payments tied to EU regional development would reopen a debate that successive governments have tried to keep separate from the narrower question of electricity trading arrangements.
Whether the talks can be insulated from other UK–EU dossiers — including trade facilitation, carbon market linkage and regulatory cooperation — will be tested as negotiating mandates are finalised and formal discussions begin.
