Next.js in United Kingdom
Next.js development services for UK and England-based teams
A Next.js development company working with UK teams. UK GDPR and PECR have drifted from the EU rules, and the difference shows up in how consent gates your scripts - not just in your policy.
British teams tend to arrive with the same assumption: that the UK is "basically GDPR" and an EU-compliant build carries over. It mostly does. The places it does not are small, specific, and all of them live in the front end.
PECR is the one that touches the code
UK data protection runs on two instruments. The UK GDPR governs personal data. PECR - the Privacy and Electronic Communications Regulations - governs cookies and anything else stored on or read from a visitor's device, and it is PECR, not the UK GDPR, that decides when your analytics script is allowed to run.
That distinction matters architecturally because PECR's scope is wider than
"cookies". Local storage counts. A fingerprinting call counts. A third-party
tag that sets nothing but reads a device attribute counts. Teams who built
their consent logic around a cookie banner and a document.cookie audit
have usually missed at least one of these.
In practice the work is: inventory what actually loads, move everything non-essential behind a gate, and make sure the gate runs before the script does rather than after. In an App Router application that is a question of where the script tag sits relative to the server/client boundary, which is why it is an engineering task rather than a procurement one.
The ICO has been explicit and public about consent banners that make rejecting harder than accepting. A build that technically gates its scripts but buries the reject control is a design problem with a regulatory tail.
Post-Brexit divergence, practically
The UK and EU regimes started identical and have been drifting. For a web build the practical questions are narrower than the headlines suggest:
- Where your data sits. UK-to-EU transfers and EU-to-UK transfers are currently straightforward, but the mechanism is a political decision that has been reviewed before. Architecture that assumes it is permanent is making a bet. Region selection at the hosting layer is cheap to keep flexible and expensive to retrofit.
- Two policies, not one. If you serve both UK and EU visitors you have two regimes to satisfy. Most teams write one policy that satisfies the stricter reading, which is defensible and simpler to maintain.
None of this is legal advice - it is the list of things that change what we build. Your counsel decides the rest.
What we are usually called in for
UK engagements skew towards inherited codebases rather than greenfield. An agency built the thing, the relationship ended, and the current team has a Next.js application nobody is confident deploying. That is a specific problem with a specific shape, and we wrote about what to do with a codebase you did not write.
The commercial version of that is migration and rescue, usually preceded by a fixed-price audit so you know what you are buying before you buy it. Where the site is a shopfront rather than an application, technical SEO and performance engineering are the two that move revenue.
