What a Shopify developer actually costs in the UK
Day rates, project rates and agency retainers, with the ranges nobody publishes — plus how to work out which of the three your problem actually needs.

Nobody publishes this, which is annoying if you are trying to budget. So here are the ranges we see in the UK market, with the caveat that anyone quoting at the very bottom or the very top should be asked why.
Day rates
- £250–£400 — junior to mid, theme edits and Liquid work. Fine for small, well-specified jobs.
- £400–£650 — experienced Shopify developer. Will design the solution, not just build the ticket.
- £650–£900 — Plus, checkout extensions, integrations, anything where getting it wrong is expensive.
- £900+ — specialist or architect work. Usually short engagements to unblock something.
A day rate is the right shape when you know exactly what you want and can brief it clearly. When you cannot, it quietly becomes the most expensive option, because you are paying for the time it takes someone to work out what you meant.
Project rates
A fixed-scope build, priced up front. Typical bands for a Shopify store:
- £3,000–£8,000 — a themed build on a premium theme, lightly customised.
- £8,000–£25,000 — a custom storefront: real design, real front-end work, sections your team can use.
- £25,000–£60,000 — Plus, B2B, complex catalogue, migrations with real data behind them.
- £60,000+ — headless, multi-region, or a platform rather than a store.
The single biggest driver of where you land is not design. It is how much of your business logic is unusual.
Retainers
£2,000–£8,000 a month covers most mid-sized stores, and it buys something different from either of the above: people who already know your store. Roughly speaking it works out cheaper than one mid-level hire, and you get a wider range of skills than any one person has.
The expensive part of any engagement is rarely the rate. It is the time spent explaining your business to somebody new.
Which one you need
A rough rule that has held up well for us:
- A defined thing with a clear end — take a project rate, so the risk of it taking longer sits with the builder.
- A steady stream of small things — take a retainer, because the overhead of scoping each one will otherwise cost more than the work.
- One unusual problem you cannot solve in-house — take a day rate for a short, sharp engagement.
What makes a quote go up
- A brief that changes mid-build. Not a crime, but it is not free either.
- Approval by committee. Three rounds of feedback from five people is its own line item.
- Undocumented existing code, especially if the last developer has gone quiet.
- A deadline that exists for a real commercial reason — peak season, a launch, a contract ending.
None of that is a reason not to ask. It is a reason to mention it early, because a quote built on a realistic picture tends to survive contact with the project.
