App development in London

London agencies charge 20 to 30% above national rates. What you are paying the premium for, when it is worth it, and what a fixed-price sprint costs.

London is the most expensive place in the UK to have software built, and sometimes that premium buys you something real.

What the London premium actually is

London adds 20 to 30% to national contractor rates. Against a £500 national median day rate in 2026, that is £600 to £650 for a mid-level developer, and £650 to £900 or more for senior and specialist engineers.

RouteTypical 2026 day rateSimple app
London agency£600 to £650£15,000 to £40,000
London senior contractor£650 to £900+Varies
Regional UK agency£500 to £550£12,000 to £33,000
App14 sprintFixed, not day-rated£2,999 or £5,999

You are paying for three things: London salaries, London property, and the account-management layer that a larger firm needs to run several projects at once. All three are real costs. None of them are your software.

When to pay it anyway

Being straight about our own address

That matters more in London than anywhere else, because "London agency" carries an implication about how you will be looked after, and we would rather set the expectation correctly before you pay than after.

Where we fit for a London business

The London businesses that suit us are the ones for whom the premium buys nothing they need: a founder with a clear idea and no technical co-founder, a professional firm wanting a client portal, an operator whose process is held together by a spreadsheet.

If you have been quoted £40,000 and four months and the scope could be fixed instead, that is exactly the gap we exist in.

Common questions

How much does app development cost in London?

London agencies typically charge £600 to £650 a day in 2026, 20 to 30% above the national median, with senior specialists at £650 to £900+. A simple app commonly lands at £15,000 to £40,000.

Are you a London agency?

We are registered in London but we are a remote studio, and our registered address is a registered-office service rather than a staffed building. We would rather tell you that than imply a Shoreditch studio we do not have.

When is a London agency worth the premium?

When you need people physically in the room with your team, when the scope is large and uncertain, or when a procurement or compliance process requires a supplier with formal structure. Those are real reasons and worth paying for.
