The loud phase of the Brexit argument is over. What has replaced it is a long sequence of technical negotiations that attract almost no public attention and matter considerably more to British businesses than the arguments that preceded them. Veterinary certification, conformity assessment, professional qualification recognition, data adequacy, energy trading arrangements — these are the substance of the relationship now, and progress on each is measured in years.
Understanding this phase requires setting aside the political framing entirely. Neither side is negotiating about identity. Both are working through a list of frictions, deciding which are worth the concessions required to remove them.
Why friction persists after a trade agreement
The agreement that governs the relationship eliminated tariffs and quotas on goods, which was the easy part. It did not eliminate the regulatory checks that arise from being outside the single market and customs union. Goods crossing the border must be documented, certified, and in some categories physically inspected, and each of those steps has a cost that falls disproportionately on small consignments and small firms.
Surveys conducted by the British Chambers of Commerce have consistently found that the burden is not evenly distributed: large exporters absorbed the compliance cost and continued, while many small exporters simply stopped selling into the EU. That is a structural change in the composition of British trade rather than a temporary adjustment.
The veterinary agreement is the biggest single prize
Food and agricultural trade carries the heaviest checks because sanitary and phytosanitary rules exist to prevent disease transmission. Every consignment of animal or plant products requires certification, and for a mixed lorry carrying dozens of product lines the paperwork is substantial.
A veterinary agreement aligning British rules with EU standards would remove most of this. The obstacle is not technical but constitutional: alignment means accepting EU rules and, in most models, a dispute mechanism referencing EU courts. That is precisely the sovereignty question the original negotiation was fought over, now presented as a narrow administrative choice. Analysis from the UK in a Changing Europe sets out the range of possible models and what each costs politically.
Services were mostly left out
Britain’s economy is dominated by services, and services received far less attention in the agreement than goods. Professional qualifications are recognised only through slow, profession-by-profession arrangements. Business travel rules vary by member state. Financial services access rests on equivalence decisions that can be withdrawn.
This asymmetry is odd given the shape of the British economy, and it reflects the sequence of the negotiation rather than an assessment of importance. Reporting from the TheCityUK on cross-border services describes how firms responded: establishing EU subsidiaries and relocating staff, which solved the commercial problem at the cost of moving activity out of Britain.
Data adequacy is the quiet dependency
Almost every modern commercial relationship involves personal data crossing borders. Britain currently benefits from an adequacy decision permitting free flow, granted on the basis that British data protection law provides equivalent protection. That decision is periodically reviewed and can be revoked if British law diverges.
This creates an unusual constraint on domestic policy: reforms to data protection law must be weighed against the risk of losing adequacy, which would impose immediate costs across every sector. The Information Commissioner’s Office operates in the knowledge that its framework is under external assessment, which is a real limit on divergence regardless of political rhetoric about regulatory freedom.
Youth mobility and the labour question
Proposals for reciprocal youth mobility schemes surface regularly and stall on immigration politics. The economic case is straightforward: sectors with acute shortages benefit from temporary workers, and reciprocity gives young Britons opportunities abroad.
The political difficulty is that any scheme increases headline migration figures, which have become a proxy for control. The Migration Advisory Committee has examined shortage occupations in ways that support targeted mobility, but the debate rarely engages with the analysis.
What incremental progress looks like
The realistic path forward is a series of narrow agreements: energy market cooperation to reduce electricity trading inefficiency, mutual recognition in specific professions, easier arrangements for touring performers and hauliers, participation in research programmes. Each is individually modest and collectively meaningful.
None of it constitutes rejoining anything, and none of it restores the position before departure. What it does is reduce the cost of a settlement both sides have accepted. That is an unglamorous project, conducted largely by officials, and it will shape British commercial life far more than the next round of speeches about it.
