How much does software development cost in London?

Less than London day rates suggest. We price fixed, not by the day — projects start from £5,000, with larger builds scoped and priced before work begins. Milestone payments mean you only ever pay for delivered work.

Are you actually based in London?

Yes — CodeLeap is registered in London and led from it, and you can meet us in Camden. Our wider engineering team works remotely, which is deliberate: you get London accountability without paying for London office overheads.

Why hire a London agency rather than a freelancer?

Continuity, mostly. A freelancer can build a first version; an agency carries it through design, development, testing and support without a single point of failure. We've shipped 50+ projects since 2019, and many of our clients have stayed with us for years — that's hard to get from one person.

How quickly can you start?

Book a call and we'll scope your project within days. Most projects take around three months from design to launch — and if you cancel within the first 21 days, you get your money back in full.

Do you only work with London businesses?

No — London is home, not a boundary. We build for charities, startups and established firms across the UK and beyond, delivering remotely with regular calls. The work on this page is a fair sample.

Real reviews from clients we have delivered for, on Clutch and elsewhere.

4.9 via Clutch

The enthusiasm, understanding of our mission, and passion from the first few minutes of the call were the deciding factors in choosing CodeLeap. Within 3 months of our app launching, we had over 1,500 downloads, appeared in leading publications from Forbes, The Metro, Marie Claire, Women's Fitness and many more, and started raising further investment.

Charlie CEO, Becon
They are incredibly diligent in the quality of work they produce, and go above and beyond when it comes to solving issues faced within the project, and to ensure we meet strict project deadlines. You never feel like you are one of many clients, and they ensure they are always there to help with any need you have, no matter how big or small.

Amelia Parmiter Marketing Manager, AWS - Marble
CodeLeap made me feel like my options were limitless in terms of what could be achieved, which was critical to me as we were creating something very unique. I'm glad I chose Codeleap over a large corporation as the personable approach resulted in a smooth and pleasant experience.

James CEO, Bearable
Working with CodeLeap was a very good experience from both a professional and personal point of view. These people know what they are doing and are both efficient and clever and made a good partner. I wouldn't hesitate to recommend CodeLeap.

John CEO, Neurometrics-Diab
CodeLeap adds so much value and goes above and beyond what I expected. CodeLeap's team is very flexible with all the different requests we've put in front of them. They've also been great with the whole business side of things, and being able to forecast for this industry is really helpful. Overall, I'm completely satisfied with their work — they've been incredibly helpful.

Johanne CEO, Cherry
Their flexibility and focus on quality were outstanding.

Mike Fenna CTO, Kite Insights
Marcelo has been wonderful throughout the process and we are very happy.
