Squarespace has roughly 4.4 million paying customers globally, with the UK market skewing toward visual-led small businesses — photographers, designers, artists, boutique restaurants, wedding venues. The platform produces undeniably good-looking sites out of the box and has the most polished editor of any major builder. The trade-off is the same trade-off as Wix: convenience now, ownership cost later.
The Squarespace cost picture
A typical UK Squarespace Business plan costs £20/month annual (£240/year). The Commerce Basic tier is £26/month (£312/year); Commerce Advanced is £40/month (£480/year). Most users also pay for at least one add-on — Acuity Scheduling at £14-£40/month, Member Areas at £12/month, Email Campaigns based on contact volume. A typical UK Squarespace stack ends up costing £35-£60/month, £420-£720/year, £1,260-£2,160 over three years — for a site that, like Wix, cannot be moved off Squarespace without rebuilding.
The same-day alternative
A bespoke website built and launched in a single trading day, hosted on UK-region edge for the first year, schema-marked, Core-Web-Vitals-tuned, on a domain in your name with source code in a git repository you own. £499 one-off Launch tier, £899 Growth tier for the multi-page builds that compete with Squarespace Business, £1,499 Pro tier for the higher-end builds that compete with Commerce Advanced. Year-two hosting: £180.
Where Squarespace genuinely wins
Squarespace's template ecosystem is the best of the builders — the editorial templates suit visual-led businesses in ways that a custom build would have to deliberately replicate. If your brand is the visual layer and you change it monthly, Squarespace's editor workflow is genuinely better than handing the visual updates back to a developer or learning the custom CMS. If you sell low-volume high-margin product through Squarespace Commerce, the per-transaction-zero pricing can beat Stripe once volume crosses certain thresholds. We say so openly on the brief call.
Where the same-day custom build wins
Three areas where the custom build is materially better. First, Core Web Vitals — Squarespace templates routinely ship 3-4 second LCP on mobile because the templates load substantial JavaScript before first paint, and the platform does not give the user enough control to fix it. The Google ranking penalty and the paid-media Quality Score penalty compound. Second, schema depth — Squarespace emits basic Organization and BlogPosting schema by default but does not let the user customise the deeper schema (Service-with-Offer, Person-with-credentials, Event-with-Performer) that lifts ranking on commercial and event-led queries. Third, the ownership question — when Squarespace renewal lapses, the site goes offline and the export is incomplete. With the custom build, the domain, hosting and source code are yours regardless of who you work with next.
The migration sequence
Same as the Wix migration in structure. Full crawl of the existing Squarespace site at the start of the build day. Search Console export of the top queries and pages over the last 16 months. 1:1 redirect map written into the new host's config. The new build ships with the existing copy intact for week one so Google sees one change at a time. DNS swap on launch day, cache purge, Search Console URL inspection on launch, health checks at day 7, 14 and 30. Where the Squarespace export produces useful static HTML, we use it as the starting point for content extraction; where it does not, we hand-extract from the live site during the crawl.
A realistic decision framework
If three of these apply to you, Squarespace is the right choice and you should not migrate: you are a visual-led business and the templates suit your brand; you change the visual layer monthly through the editor; you accept the £35-£60/month cost as the price of the convenience; Core Web Vitals do not materially affect your traffic or ad-spend economics; you do not need integrations beyond Squarespace's native set. If three or more apply, the same-day custom build is the better economic and operational choice: you want to own the domain, source code and hosting; the £35-£60/month adds up against your operating budget; Core Web Vitals matter for your paid media or your organic ranking; you need integrations Squarespace does not native-support; you will leave the design alone for ten months at a time once it ships.
