How Much Does a Shopify Migration Cost in the UK? (2026 Prices by Store Size)

Most established UK stores pay between £6,000 and £15,000 for a Shopify migration in 2026. A simple store with a small range can move for £3,000 to £7,000, and a complex build with trade pricing, integrations or multiple markets runs from £15,000 to £40,000 and beyond. Where your store lands depends far more on what it does than on how many products it sells.

Those ranges cover moving an existing store from another platform: Magento, WooCommerce, Wix, or an ageing bespoke system. If you are pricing a brand-new store instead, our guide to ecommerce website costs in the UK covers that. This one is about the move: what the work involves, what it costs at each tier, how long it takes, and how to protect the sales and rankings you already have.

We build on Shopify, WooCommerce and Shopwired, and we have carried out full platform migrations including a heritage jewellery and silver care brand moved from Craft CMS to Shopify with its search visibility intact. The figures below are the ranges we quote and the ones we see across the UK market.

How much does a Shopify migration cost by store size?

Most migrations fall into three tiers, and the clearest way to read them is by complexity rather than by catalogue size alone.

Figures reflect 2026 UK agency pricing, based on our own project quoting and published market ranges. They cover the migration project itself; Shopify's monthly plans and running costs are separate and covered further down.

The reason quotes for the same store can vary so widely is that a migration is two projects in one: a rebuild of the store on Shopify, and the careful transfer of everything the old store holds. Agencies weight those two halves differently, which is why the section below matters more than the headline number.

What does a Shopify migration include?

A properly run migration covers six areas, and comparing quotes line by line against this list tells you quickly what each agency has and has not priced in:

• Discovery and platform audit: mapping what the current store does, which features earn their keep, and what the new store needs to achieve.
• Design and build on Shopify: either adapting a quality theme or designing the store around your brand, rebuilt to convert rather than copied across pixel by pixel.
• Data migration: products, variants, customers, discount structures and order history, moved across and checked, so you keep your trading history and your customers keep their accounts.
• URL redirect mapping: every address on the old store pointed permanently to its equivalent on the new one, which is what carries your Google rankings through the move. Google's own site move guidance describes exactly this process.
• Integrations: reconnecting the systems your business runs on, from accounts software and stock management to fulfilment, email marketing and reviews.
• Testing, launch and training: a full test order cycle, a managed go-live, and a proper handover so your team can run the store from day one.

The strongest single question to ask any agency quoting you: "walk me through your redirect and data migration process." The answer separates teams who migrate stores for a living from teams who build new stores and improvise the moving part.

What drives the cost up or down?

Integrations move the number more than anything else. Reconnecting Shopify to an accounts package, a warehouse system or a bespoke back office is skilled work, and one awkward integration can shape an entire quote. If your store runs on connections to other software, expect the middle tier at least.

Custom features come second. Anything your current platform does that Shopify does not do out of the box - subscriptions, trade pricing, a product configurator - has to be rebuilt with apps or custom development. Each one adds real cost, and this is also the moment to ask whether every old feature deserves to survive the move.

Data complexity matters more than data volume. Ten thousand simple products migrate more easily than five hundred with layered variants, customer-specific pricing and years of order history that has to reconcile with your accounts.

Design choice sets the floor. Adapting a well-made Shopify theme keeps a simple move near the bottom of its tier, while a fully bespoke design adds several thousand pounds and is usually worth it for established brands whose store is their main shop window.

Will you lose sales or rankings during the move?

Handled properly, no. The new store is built and tested in parallel while your current one keeps trading, so there is no gap in sales, and the switch itself happens at a quiet moment with the old store held as a fallback. Your rankings are carried by the redirect map: when we moved that heritage brand from Craft CMS to Shopify, a complete change of platform and URL structure, its search visibility carried straight through the move.

The businesses that do lose ground in a migration almost always skipped one of two things: the page-by-page redirect map, or benchmarking their search performance beforehand so the settling period could be monitored against real numbers. Both should be named line items in any quote you accept.

What does Shopify cost to run after the move?

Budget for the migration and the running costs together, because part of the point of moving is what happens to your monthly overhead afterwards. Shopify's UK plans start at around £19 a month on Basic with annual billing and rise to £259 or more on Advanced, plus apps, and payment fees from around 2% plus 25p per order on the basic plan. We break the full monthly picture down - apps, maintenance and the fee on every sale - in our ecommerce cost guide, and compare how the platforms treat fees in Shopify vs WooCommerce vs Shopwired.

For many businesses arriving from an ageing platform, the running-cost story improves: hosting, security patching and plugin firefighting are absorbed into the platform fee, and the developer time that went on keeping the old store standing gets freed up for work that grows the business.

So what should you budget for a Shopify migration?

A realistic way to set the budget, depending on where your store sits today:

• A small store on a struggling platform: £3,000 to £7,000, and often the simplest decision, because the move itself is most of the work.
• An established store with real trading history: £6,000 to £15,000, with the redirect map and data migration treated as seriously as the design.
• A complex or trade business: £15,000 to £40,000 and beyond, where the integrations and B2B features are the project and deserve the most scrutiny in every quote.

One honest caveat belongs alongside those numbers: not every store should move. If your current platform is well supported, integrates cleanly with your systems and is not holding back your growth, staying put and investing the budget in conversion or marketing can be the better call. A good agency will tell you that plainly before quoting.

What should you prepare before asking for quotes?

A little preparation makes every quote you receive sharper and easier to compare, and it usually takes an afternoon. Before you speak to anyone, gather:

• Your platform and version: what the store runs on today, and who currently supports it.
• The shape of your data: roughly how many products and variants you sell, how many customer accounts you hold, and how many years of order history you want to keep.
• The systems your business runs on: accounts software, stock or fulfilment tools, email marketing, and anything else the store connects to.
• The features you use daily as opposed to the ones switched on years ago and quietly abandoned: paying to rebuild a feature nobody uses is the most avoidable cost in any migration.
• A search benchmark: an export of your Google Search Console data, so the move can be measured against real numbers.

Arriving with that list does more than speed things up. It signals to every agency quoting that the project will be run properly, and the quotes that come back tend to be more considered because of it.

The migrations that pay for themselves are the ones scoped around the business rather than the platform. Move because your current store is limiting what you can do, price the redirects and the data as carefully as the design, and the new store starts earning from the week it goes live.

A Shopify migration is a significant project, but it is a well-trodden one, and for a store that has outgrown its platform it is usually the investment that unlocks the next stage of growth. Cost it with the full picture - the move, the running costs and the features worth carrying forward - and the number becomes a business decision rather than a leap of faith.
