Quick answer: a well-vetted offshore development partner typically costs 40–60% less than a London agency for comparable senior-level output — the gap is almost entirely cost-of-living and overhead, not skill. The risk isn't offshore development itself; it's skipping the vetting process that separates a genuinely reliable partner from one that looks fine in a sales call.
What to Actually Check Before Signing
Ask for a reference from a project of comparable scope and complexity to yours, not just a generic client list — a portfolio full of small marketing sites doesn't tell you anything about a partner's ability to deliver a complex platform. Ask exactly how code review and testing work day-to-day, not whether they "have a QA process" — a specific, concrete answer beats a confident but vague one every time. And ask what timezone overlap you'll actually get for daily communication; a partner with zero working-hours overlap with the UK creates a real coordination cost that erodes the savings on paper.
Realistic Cost Savings, Not Marketing Numbers
The pricing gap between a London agency and a well-vetted offshore partner is real and consistent — roughly 2–3x for comparable senior-level output, which we've documented in detail for UK custom software costs generally. Treat any offshore quote radically below that range with real skepticism — it usually means junior-only staffing, a shortcut on testing, or both, not a genuinely better deal.
Red Flags Worth Taking Seriously
Pressure to sign before you've seen the team who'll actually work on your project (not just the salesperson), no clear answer on what happens to intellectual property and source code ownership, a quote that's a single lump sum with no phase breakdown, and no concrete process for handling scope changes mid-project — these predict a difficult engagement more reliably than any single technical red flag.
Structuring the Engagement to Protect Yourself
A written scope of work with clear milestones and acceptance criteria per phase matters more than any contract clause — it's what actually lets you tell, objectively, whether a delivery is on track. NDAs and IP-assignment terms should be standard and non-negotiable from the partner's side; a hesitation there is itself a red flag. And a trial phase — a smaller, contained first project before committing to a larger engagement — is worth the modest extra coordination cost for the risk it removes.
