Ask a UK small-business owner what they would do if their website builder doubled its price tomorrow, and most will confidently say “I'd move elsewhere”. Ask how, and the conversation falters. On Wix, Squarespace and GoDaddy, “moving elsewhere” is not a simple DNS change — it is a full rebuild from scratch. The only copy of your website is the one on the vendor's servers; leaving means losing everything and starting over on a new platform. This is vendor lock-in, and in 2026 it is the single most consequential decision a UK SME makes about their online presence — yet most owners sign up without understanding it. This guide explains what lock-in means platform by platform, the hidden costs it creates, how to avoid it, and why it matters more now than it did five years ago.

Vendor lock-in is the situation where leaving a supplier is prohibitively expensive or practically impossible. On a website builder, it takes a specific form: the content, design and structure of your website are stored in a proprietary format on the vendor's servers, and the vendor does not let you download a working copy of the site.
Your content (text and images you uploaded) is yours in the legal sense. The site itself — the layouts you arranged, the design tweaks you made, the navigation structure, the URL paths — is not portable. If you cancel the subscription, the site disappears. If you want to move to a different platform, you start over.
This is not theoretical. UK business owners who signed up on Wix in 2019 and discovered in 2024 that they had outgrown the platform have genuinely had to rebuild from scratch. Contact form submissions, blog posts, product catalogues, page structures and URL paths all had to be reconstructed manually. For a site with 30 pages and three years of content, that is typically 40–80 hours of work.
Lock-in is the cost of leaving, expressed as hours and money. Every builder has some lock-in — but the severity varies wildly, and the economics of a five-year relationship hinge on which end of that spectrum you started at.
A clear-eyed 2026 summary, based on the actual export features each platform offers at the time of writing.
Export available: None. Wix offers no way to download a working copy of your website. You can individually copy-and-paste text from each page and right-click-save each image, but layouts, design, CSS, navigation and URL structure do not come with you.
What this means in practice: leaving Wix means rebuilding on a new platform. For a 10-page site with blog, that is 15–30 hours. For a 30-page site with e-commerce, 40–80 hours. For most UK SMEs this is the reason they stay on Wix even after price hikes — the rebuild cost exceeds the price increase.
Severity: High. No partial mitigation available.
Export available: Partial. Squarespace lets you export blog posts and some basic page content in WordPress-compatible XML. Layouts, custom styling, navigation structure, form data and e-commerce content do not export.
What this means in practice: for a blog-centric site, the blog content can be moved with some effort. For a typical brochure / services site, the XML export covers perhaps 30% of what you need; the other 70% is manual rebuild. A full 30-page Squarespace-to-WordPress migration takes 20–50 hours.
Severity: Moderate. Partial mitigation through XML export for content-heavy sites.
Export available: None. Like Wix, GoDaddy's builder does not allow any form of site export. Individual pages can be manually copied but the site as a whole is locked to the platform.
What this means in practice: identical to Wix. Leaving means rebuilding. Many UK owners discover this only at renewal when the price doubles.
Severity: High.
Export available: Product catalogue (CSV), customer list (CSV), order history (CSV). Storefront theme is editable Liquid but not portable to non-Shopify stacks without complete rewrite.
What this means in practice: product and order data move relatively cleanly to WooCommerce or another e-commerce platform. Storefront design and customisations do not — a bespoke Shopify theme becomes worthless once you leave Shopify. Apps (which Shopify stores often rely on heavily) all disconnect.
Severity: Moderate to high for theme-customised stores. Low for stock-template stores focused on product catalogue.
Export available: Full. WordPress is self-hosted software; you own the database and the files. Moving between hosts is a standard migration. Content exports in WordPress XML. Themes and plugins are portable (subject to licence). URL structure can be preserved.
What this means in practice: no lock-in. Moving a WordPress site from SiteGround UK to Kualo or Krystal is a routine operation. Moving to a different CMS is harder but content is always exportable.
Severity: None.
Export available: Full ZIP export of the entire site — clean HTML5, CSS/SCSS, JavaScript, images. Can be hosted on any standard web server as static files.
What this means in practice: no lock-in. Unusual for a bundled-hosting builder. If you ever decide to host the site elsewhere, you download the ZIP, upload it to the new host, and the site works. URL structure, design, content all preserved.
Severity: None.
| Platform | Export | Rebuild time if leaving (10-page site) | Severity |
|---|---|---|---|
| Wix | None | 20–40 hours | High |
| Squarespace | Partial (blog XML) | 15–30 hours | Moderate |
| GoDaddy | None | 20–40 hours | High |
| Shopify | Product CSV | Depends on customisation | Moderate |
| WordPress | Full | ~2 hours DNS only | None |
| Sitejet | Full ZIP | ~2 hours DNS only | None |
Lock-in has always been a consideration. Three 2025–2026 developments have made it matter more.
Wix, Squarespace and GoDaddy have all raised prices multiple times in the last 24 months. Owners on older legacy plans have been migrated to newer more-expensive tiers. A locked-in customer has no leverage to negotiate; a portable customer can threaten to leave credibly.
A builder that performed adequately in 2019 may now be structurally slower than current competitors. On Core Web Vitals, Wix and older Squarespace templates lag behind lean alternatives; for UK local SEO this translates to ranking losses. Owners who want to fix the ranking issue find the only available fix is to change platform — at which point lock-in bites.
Post-Schrems II, data transfers to US servers require additional Standard Contractual Clauses and/or the UK International Data Transfer Addendum. UK-headquartered businesses increasingly want EU or UK data residency. Moving from a US-based builder to a UK/EU-based one is a common 2026 migration — and lock-in makes it painful.
Every builder is adding AI features at different speeds and with different trade-offs. The platform that was best for you in 2023 may not be best in 2026. Lock-in prevents you from shifting to where the better tool is.
Small UK ISPs closing, rebranding or being acquired is increasingly common. An owner whose domain is registered with their builder provider (a common GoDaddy pattern) faces compound migration if the builder changes hands or pricing.
Lock-in costs are invisible until triggered — at which point they arrive all at once.
When the annual renewal price doubles, a locked-in customer can only accept, negotiate from a position of weakness, or absorb a rebuild. Most accept. A portable customer can credibly threaten migration, which often unlocks a retention discount.
If the platform pivots away from your use case (Shopify announcing a shift toward enterprise merchants, or Wix deprecating a feature you relied on), a locked-in customer must adapt or rebuild. A portable customer can leave for a better-aligned competitor without rebuild cost.
When rebuilds happen on new domains or with changed URL structures, Google treats the new site as a new site. Rankings accumulated over years can take weeks or months to recover. A portable customer preserves URL structure; a locked-in customer often cannot.
New tools — a better e-commerce platform, a stronger SEO plugin, a superior analytics tool — become available. Locked-in customers can only adopt them if the platform chooses to support them. Portable customers can move to where the tool is.
A freelance UK developer familiar with HTML, CSS and JavaScript can work on almost any site that exposes standard code. A Wix-specific or Squarespace-specific developer is rarer and charges more. Lock-in narrows your pool of available help and drives up hourly rates.
Unlikely but non-zero. Web platforms go through acquisition, rebranding, and occasional collapse. A portable customer has a copy of their site regardless. A locked-in customer is dependent on the platform's continued existence.

Representative patterns observed among UK SME migrations in the last 24 months.
Original Wix Business plan: £24/month inc. VAT (£288/year). Five years of operation, 14 pages including blog and customer testimonials. Wix renewed at full list price in 2024 after a promotional year, a 40% increase. Owner investigated migration; no Wix export available. Rebuild on Sitejet Builder took a weekend plus three evenings (roughly 18 hours). New running cost: £75/year. Break-even on rebuild time: 9 months. Four years of saved subscription afterwards — approximately £850 by end of 2028.
GoDaddy Online Store plan hit £25/month at renewal after £10/month intro year. No export. Rebuild on self-hosted WordPress + WooCommerce took 40 hours (more complex shop with 80 products). Ongoing cost dropped from £300/year to £150/year plus 2 hours/month maintenance. Break-even: 10 months including time value.
Six-year-old Squarespace site, 8 pages plus blog with 22 posts. Squarespace Business plan at £33/month inc. VAT. Owner exported blog XML (recovered 90% of blog content cleanly) and manually rebuilt the rest. Total rebuild time: 14 hours. Annual cost dropped from £396 to £75. Break-even on time: 5 months; afterwards pure savings.
Wix Advanced plan at £45/month inc. VAT (£540/year). Firm needed custom CRM integration that Wix did not support. Rebuilt on self-hosted WordPress with a freelance developer (£2,200 one-off). Annual WordPress cost £180. Break-even: 3 years at the previous subscription level. Firm gained control of roadmap, CRM integration and full code access.
The consistent pattern: migration always pays back, eventually. The question is whether you need to migrate urgently (forced by price hike, feature loss or ranking collapse) or whether you had portability built in from day one. The latter is always cheaper.
When a US-headquartered builder raises USD pricing, UK customers bear both the USD hike and the exchange-rate shift. Sitejet Builder via smartxhosting.uk holds GBP pricing stable regardless of USD/GBP movement.
When something breaks on Friday afternoon, a US builder's support queue typically opens at 2 pm UK time earliest. A UK-headquartered provider resolves in hours, not until Monday. Lock-in to a US provider extends that downtime indefinitely across a five-year relationship.
GoDaddy, for example, frequently bundles domain registration with hosting. Moving hosting requires either transferring the domain (a 5–14 day process with ownership verification) or managing DNS remotely. Registering the domain separately at Nominet-direct (via smartxhosting.uk or 123-reg) avoids this dependency — domain and site live in different accounts and can be detached independently.
If your business e-mail is on the same provider as your website, changing platforms means migrating mailbox contents too. That is a separate project. Keeping mailbox and website on separate providers (or on Sitejet Builder hosting which bundles both cleanly) reduces migration complexity.
Post-Schrems II, the UK and EU have different adequacy frameworks for US data transfers. If either framework changes materially (as has happened several times since 2020), US-hosted site owners may need to migrate data residency urgently. Sitejet Builder's EU-only hosting sidesteps this risk.
If a UK builder materially degrades service quality mid-contract, the Consumer Rights Act and Consumer Contracts Regulations 2013 provide limited remedies. Still, the practical reality is that migration is faster than litigation. Portability matters more than contract rights.
A simple five-question checklist before signing up to any platform.
.co.uk at a Nominet-accredited registrar (smartxhosting.uk, 123-reg, Nominet-direct) in your own name, not the builder's. Maintain DNS control separately.If any answer is no or “sort of”, recognise the lock-in trade you are making. Sometimes it is worth it (Shopify's best-in-class e-commerce can justify the lock-in for a large-catalogue store). Often it is not.
Sitejet Builder was designed — unusually for a bundled-hosting builder — with portability as a core feature rather than an afterthought.
.co.uk at smartxhosting.uk or any Nominet-accredited registrar in your own account. DNS is under your control; you can point it at Sitejet today and anywhere else tomorrow.If smartxhosting.uk raised prices 50% next year (it has not), you could download your site, move to a different UK host and be live within 2 hours. Your URL structure, design, content and assets all come with you. Any future freelancer or agency can maintain what you built. That is what portability looks like in practice.
Self-hosted WordPress offers the same level of portability, via a different mechanism (you own the database and files). For a UK SME choosing between managed-builder simplicity and content-management-system flexibility, both Sitejet and WordPress clear the portability bar. The other major builders do not. For the head-to-head see our website builder vs WordPress comparison.
If this guide has arrived too late and you are already on Wix, GoDaddy or a similar locked-in platform, here is the pragmatic 2026 playbook.
Sitejet Builder for speed and low maintenance; WordPress for full control and deep SEO tooling. Our website builder vs WordPress guide covers the trade-off.
List every existing URL from Google Search Console or by crawling the site with Screaming Frog (free for 500 URLs). Map each old URL to a new URL on the destination. Where the URL does not naturally match, plan a 301 redirect.
From Wix / GoDaddy: copy-and-paste body text, right-click-save each image, note page titles and meta descriptions. From Squarespace: export blog XML, then handle non-blog pages manually. Budget 10–15 minutes per page.
Pick a template that roughly matches the current design, customise, paste content, upload images, add metadata. On Sitejet Builder with AI content assistance this is 1–3 hours per page for a first-time user, faster for experienced.
Verify every page has title, meta description, H1 and alt text. Check Core Web Vitals in PageSpeed Insights. Submit to staging URL for full review before going live.
Update the .co.uk domain to point at the new host. 301 redirects on the old URLs where possible (not always possible on Wix/GoDaddy, which is why preserving exact URLs matters).
Add the new site to Google Search Console (same property if URL unchanged; new property if URL changed), submit the sitemap.xml, and request indexing on key pages. Google typically revalidates within 2–6 weeks.
Only after the new site has been live and crawled for at least a week. Do not cancel before DNS has propagated and Google has re-indexed.

Q: Is all lock-in bad?
A: No. Sometimes lock-in is a legitimate trade for capability. Shopify's e-commerce tooling may justify the platform lock-in for a large-catalogue UK store. But the trade should be made consciously, not stumbled into at the signup form.
Q: Can I legally force Wix or GoDaddy to give me a copy of my site?
A: Not under current UK consumer law. The Consumer Rights Act 2015 provides limited remedies for services that are not performed with reasonable care and skill, but does not compel export functionality the provider never offered. Your leverage is commercial (threatening to cancel and publicly review), not legal.
Q: How much time does a typical UK SME lose migrating off a locked-in builder?
A: 15–40 hours for a 10-page site, 40–80 hours for 30+ pages with e-commerce. At a realistic £25–£50/hour time-value, that is £400–£4,000 of hidden cost. Factored over a 5-year subscription relationship, it is often the largest single line item.
Q: Does exporting a Sitejet site preserve SEO authority?
A: Yes, if you maintain the domain and URL structure. The exported HTML files render identically on any host. Google sees the same URLs and content; ranking is preserved.
Q: What about white-label builders — are they more portable?
A: Depends on the platform. Duda offers some export; GoDaddy white-label does not. For agency lock-in considerations see our white-label website builders for UK agencies guide.
Q: Can I keep my domain if I cancel my website builder?
A: If the domain is registered in your own account at a Nominet-accredited registrar, yes. If it is bundled with the builder's subscription and registered in their account, you may have to transfer it (5–14 days) or lose it at renewal. Register domains separately from day one.
Q: Is WordPress truly lock-in free or is there something I'm missing?
A: WordPress core has no lock-in. Some page-builder plugins (Elementor, Divi) create lock-in within the WordPress ecosystem — content edited with those plugins depends on the plugin to render cleanly. Choose plugin-independent themes where possible.
Q: My builder claims I can export. How do I verify?
A: Actually do the export. Download the file, inspect the contents. If it is only blog content in XML and no layouts, CSS or images, that is partial export, not full. Full export produces a folder of HTML / CSS / JS / image files that render when opened locally.
Q: What happens to form submissions and customer data when I migrate?
A: Form submissions live in your inbox (if the form forwards to e-mail); they are yours regardless. Customer accounts on an e-commerce store require CSV export — all major platforms offer this for customer and order data. UK GDPR requires that users can access their data, but the builder must provide tooling to export it; check before signing up.
Q: Will my rankings survive a migration?
A: If you preserve the domain, preserve the URL structure and implement 301 redirects where URLs must change, rankings typically recover fully within 2–6 weeks. If the migration changes the domain or URL structure without redirects, rankings can take 3–6 months to rebuild.
