Quick answer: custom software development in the UK typically costs £8,000–£25,000 for a focused MVP, £25,000–£80,000 for a mid-size platform with integrations, and £80,000–£150,000+ for an enterprise-grade system. A London agency generally sits 2–3x above a well-vetted remote partner for comparable output.
What Actually Drives the Price
Scope and feature count matters more than almost anything else — a five-screen MVP and a twenty-module platform aren't the same category of project, and pricing should reflect that before anything else is discussed. Integrations (payment gateways, third-party APIs, legacy system connections) add cost non-linearly, since each integration brings its own edge cases and testing burden. Compliance requirements — GDPR data handling, industry-specific regulation (FCA for fintech, MHRA-adjacent for healthtech) — add real, justified cost, not padding. And team location is the single biggest lever UK businesses actually control: the same senior engineering output costs meaningfully more from a London-based team than from a well-vetted remote one, purely on cost-of-living and overhead grounds, not skill.
Realistic Cost Bands
| Project type | Typical UK agency cost | Typical remote-partner cost |
|---|---|---|
| MVP (5–8 core features) | £15,000–£40,000 | £8,000–£20,000 |
| Mid-size platform with integrations | £50,000–£120,000 | £25,000–£65,000 |
| Enterprise system | £150,000+ | £70,000–£150,000 |
These are directional, not a quote — actual pricing depends on your specific scope, but the ratio (roughly 2–3x between London-agency and well-vetted remote-partner rates for comparable senior-level output) holds fairly consistently across project sizes.
How to Get an Accurate Quote, Not a Guess
Come to the first call with a written scope, even a rough one — "build me an app" gets a wide, defensive range; a documented feature list gets a tight one. Ask any quote to break down by phase (discovery, build, testing, deployment) rather than one lump sum, so you can see where the money actually goes. And ask explicitly what's included in post-launch support — a cheap quote that excludes bug-fix support for the first 90 days isn't actually cheaper once you account for what happens after launch.

Frequently Asked Questions
How much does custom software development cost in the UK? Typically £8,000–£25,000 for a focused MVP, £25,000–£80,000 for a mid-size platform with integrations, and £80,000–£150,000+ for an enterprise system — with London agency rates generally running 2–3x above a well-vetted remote partner for comparable output.
Why is a London agency more expensive than a remote development partner? The gap is almost entirely cost-of-living and overhead, not skill — a well-vetted remote partner can run the same process, code review standards, and delivery accountability at a fraction of London's operating cost base.
What should I have ready before requesting a quote? A written scope or feature list, even a rough one — vague requests get wide, defensive price ranges, while a documented scope gets an accurate, phase-by-phase breakdown.
