Quick answer: Apptechies is a London-founded custom software development company building bespoke enterprise systems for UK businesses, with GDPR and Data Protection Act 2018 practices built into the architecture from day one — not a compliance checklist applied before launch.

Why UK Businesses Choose Us

A Software Partner That Understands UK Compliance, Not Just UK Time Zones

Plenty of agencies will build you software. Fewer understand what changes when your users, your data, and your regulator are all in the UK. Founded in London in 2018, we've spent 8+ building systems where GDPR, the Data Protection Act 2018 and sector rules aren't an afterthought — they're part of the architecture conversation on day one.

That approach has shipped 600+ solutions across 25+ industries, with a 99% client satisfaction rate.

Where Software Meets UK Compliance

Regulation Isn't a Feature We Add Later

UK GDPR & Data Protection Act 2018

Data minimisation and lawful-basis mapping are architectural decisions we make before writing a single screen.

Sector-Specific Regulation

FCA-aware architecture for FinTech, NHS DTAC awareness for healthcare — scoped during discovery, not after a rejected audit.

UK/EU Data Residency

Hosting scoped to UK or EU cloud regions where your data-residency requirements call for it.

Common Questions

Everything You Need to Know Before You Hire.

The questions we hear most from teams hiring a custom software development team. Don't see yours? Ask us directly on the right.

A focused internal tool typically runs $20,000–$50,000, while a full enterprise platform with multiple integrations can run $150,000+. We scope against your actual requirements after a discovery call rather than a generic range.

A focused MVP typically takes 8-12 weeks. A full enterprise platform with multiple integrations usually runs 20-30 weeks depending on scope.

Full working-hours overlap, no cross-border data-transfer complications, and a team that already understands UK regulatory context — without the premium of an in-house hire.

GDPR and the Data Protection Act 2018 shape data-minimisation, storage and consent decisions from the architecture phase — we scope these during discovery, not as a pre-launch retrofit.

FinTech, healthcare, logistics and eCommerce see the clearest ROI, though the underlying discipline — solving your specific workflow, not a generic template — applies across all 25+ industries we've worked in.

Yes — every engagement includes a post-launch support window, and most clients continue with an ongoing maintenance and iteration retainer.

Yes — we regularly bridge new builds into legacy ERPs, on-premise databases and internal APIs that were never designed for modern integration.
