Wix vs Custom Website: What's Actually Better in 2026?
Side-by-side comparison of Wix and custom-built websites for UK small businesses. Speed, SEO, design freedom, three-year total cost, and ownership — the honest answer from a London web designer.
I'm going to be straight with you: Wix isn't always the wrong choice. But for most established local businesses in 2026, a custom website will perform better, cost less over time, and give you a lot more control.
Here's the honest comparison, with the side-by-side data first.
Wix vs Custom — side-by-side comparison

|---|---|---|
| Mobile load time | 4–7 seconds (typical) | Under 2 seconds |
| Lighthouse performance score | 50–60 (typical) | 90–100 |
| Total page weight | 2–5MB | Under 500KB |
| LocalBusiness schema control | Limited / surface only | Full schema, geo, areas served |
| Year 1 cost | £200–300 | £1,500–2,500 |
| Year 3 total cost | £648–900 | £1,660–2,800 |
| Code ownership | No — locked to platform | Yes — fully owned |
| Design uniqueness | Template-based, limited | Bespoke from brief |
| Time to launch | Days (DIY) | 2–4 weeks |
| Ongoing platform fee | £10–25/month forever | £5–15/month hosting only |
| Migration if you outgrow it | Full rebuild required | Move hosts anytime |
Why are Wix websites so slow on mobile?
Wix sites are slow because the platform loads its own scripts, tracking code, and editing tools on every page, whether your site needs them or not. The result is 2–5MB of overhead that has to download before any of your content shows. A typical Wix mobile load is 4–7 seconds against under 2 seconds for hand-coded.
This is the biggest practical difference, and it matters more than most people realise. Wix sites carry a lot of bloat. The platform loads its own scripts, tracking code, and interface tools on every page, whether you need them or not. The result is slow load times, and slow load times hurt your Google ranking.
A custom-built site only loads what it needs. No platform overhead. With a lightweight hand-coded site, hitting a Lighthouse performance score of 90+ is achievable. Most Wix sites sit in the 50s or 60s.
When someone in Lewisham searches for your service on their phone, a page that loads in one second beats a page that takes four. Every time. Google's Core Web Vitals measure exactly this and feed the result directly into ranking.
What can a custom website do for SEO that Wix can't?
Custom sites give you full control over the code — which means full control over schema, page structure, and Core Web Vitals. Wix has surface-level SEO (titles, descriptions, alt text) but caps the deeper signals: bloated HTML, limited LocalBusiness JSON-LD, awkward URL structures, no real control over Core Web Vitals.
Wix has improved its SEO tools in recent years. You can add title tags, meta descriptions, and alt text. That's fine.
But the deeper SEO stuff is where it falls short. Wix generates messy code that's harder for Google to crawl. Structured data (the schema markup that helps Google understand exactly what your business is and where you are) is limited and difficult to implement properly. URL structures can be awkward.
A custom site gives you full control over the code. You can add exact LocalBusiness schema with the most specific subtype (MedicalBusiness, BeautySalon, Restaurant), full geo coordinates, the complete list of areas served, structured opening hours, credentials, and price range. These are the signals that help a local business rank in the right place for the right searches.

How much design freedom do you actually get with Wix?
Wix gives you a lot of options on the surface — hundreds of templates, drag-and-drop editing, lots of colour and font choices — but the layouts are constrained by the platform. A custom design starts from your business: your brand, your customers, your goals. Nothing is off the shelf.
Wix gives you a lot of options on the surface. Hundreds of templates, drag-and-drop editing, lots of colour and font choices.
In practice, the templates all start to look the same. The layouts are constrained by the platform. You're always working within someone else's system, and it shows. Visitors who look at a lot of small business sites can usually spot a Wix or Squarespace template in seconds — the page rhythm, the section blocks, the stock interaction patterns.
A custom design starts from your business. Your brand, your customers, your goals. Nothing is off the shelf. For a local business in East Dulwich or Crystal Palace, that difference shows in how professional the site feels when someone lands on it. Trust signals start in the first three seconds.
What's the real cost of Wix vs custom over 3 years?
Wix Business plan = £648–792 over three years. Squarespace Business = £756. A comparable custom site = £1,500–2,500 build + £80–200/year hosting (£1,660–2,800 over three years). Custom is more expensive year one, roughly even by year two, and cheaper from year three onward. You also own the asset.
Wix charges you monthly, indefinitely. The Business plan, which you need for a proper custom domain and no Wix ads, sits around £18–22 a month. Squarespace's Business plan is £21 a month. Over three years that's £648–792 (Wix) or £756 (Squarespace) spent on something you can never fully own or export.
If Wix changes their pricing — and they have, several times — or you want to move to a different platform, you're starting from scratch. You don't own the code.
With a custom site, you pay once for the build. Hosting is separate and cheap, usually £5–10 a month for a static site on Vercel or Cloudflare. And you own everything. The code, the design, the content. You can move hosts. You can hand it to a different developer. It's yours.
Do you really own your Wix website?
No. You rent it. Your content lives in Wix's database. Your design uses Wix's components. Your code is generated by Wix's engine. You can export the text and images, but the site itself cannot be moved. If you ever want to leave the platform, you're rebuilding from scratch — usually with a freelancer for £1,500–2,500.
This is the part most owners don't realise until they want to leave. Your Wix or Squarespace content can be exported as plain text and images. The design and structure cannot. You can't take a Wix site to another host. You can't hand the code to another developer. The site itself is locked to the platform.
With a custom site, the code lives on your hosting account, in your own files. If your designer disappears or you simply want to move to a different one, you can. The site is an asset on your business's balance sheet, not an ongoing rental.
When is Wix actually the right call?
Wix makes sense in two specific situations: testing a brand new business idea before committing budget, or as a placeholder while you save up for a proper site. For an established business in SE London with real customers and real word of mouth, you deserve something better than a template.
If you're testing a business idea and genuinely don't know if it'll take off, Wix lets you get something online fast without spending much. That's a legitimate use case.
If you're just starting out and need a placeholder while you save up for a proper site, Wix is fine for that.
But if you're an established business in South East London and your website is how people find you and decide to contact you, you deserve something better than a template. A custom site at £1,500–2,500 pays back through better rankings, better conversions, and no monthly platform fee eating into your margins forever.
The bottom line
Wix is fine for getting started. A custom website is better for growing.
If you're past the "testing the idea" stage, the investment in a custom site pays back through better Google rankings, faster page loads, deeper local SEO, and no ongoing platform fees eating into your margins every month.

Wix vs Custom — frequently asked questions
The questions UK small business owners ask most when deciding between Wix and a custom build.
Is a custom website really better than Wix for SEO?
Yes, structurally. Wix generates bloated code that limits page speed — most Wix sites score 50–60 on Google's Lighthouse mobile test against 90+ for hand-coded custom sites. Page speed is a confirmed Google ranking factor (Core Web Vitals). Custom sites also let you implement deep LocalBusiness JSON-LD schema with full geo coordinates and areas served, which Wix's schema tools don't expose properly.
How much faster is a custom website than Wix?
Typically 3–5x faster on mobile. A well-built custom website loads in under 2 seconds on a 4G connection. A typical Wix site loads in 4–7 seconds because of the platform scripts that load on every page. Over half of mobile users abandon a site that takes more than 3 seconds to load — so the speed gap directly translates to lost customers.
Do you actually own your Wix or Squarespace site?
No. You rent it. The code, design, and hosting all live on Wix or Squarespace's platform. You can export some content (text, images) but not the design, code, or structure. If you want to move to another platform you're rebuilding from scratch. With a custom site you own the code outright and can move hosts anytime.
What does Wix actually cost over three years?
A Wix Business plan costs £18–22 a month, which over three years totals £648–792. Squarespace's Business plan is £21 a month, totalling £756 over three years. A typical UK custom freelance site costs £1,500–2,500 once plus £80–200/year hosting. Stagg Studio specifically: from £350 build + £30/month covering hosting, management and SEO — about £1,430 over three years for a real custom site you own. Custom is cheaper than Wix on either model from year three onwards.
When does Wix actually make sense?
Wix makes sense when (1) you're testing a brand new business idea and need something live in days, (2) you have zero budget for a custom build, or (3) you want to manage everything yourself and have time to learn the platform. For an established local business with real customers, Wix is almost always the wrong choice past month 12.
Can I migrate from Wix to a custom website?
Yes, but it's a rebuild, not a migration. The content (text, images, logo) can be exported and reused. The design, code, and structure cannot — they're locked to Wix's platform. A good freelancer can take the existing copy and build a faster custom site in 2–3 weeks. Stagg Studio handles the redirect map and SEO continuity so existing rankings transfer to the new site.
Is Squarespace better than Wix?
Marginally. Squarespace produces slightly cleaner code and the templates feel more designed. The fundamental limitations are the same: platform overhead caps performance, schema control is limited, you don't own the code, and the monthly fee runs forever. The Wix vs custom comparison applies to Squarespace too.
