Website builder costs almost never stay at the advertised £15 a month. Across the UK businesses we have migrated off Wix and Squarespace, the settled figure lands between £55 and £90 a month by year two. Over three years that is roughly £2,000 to £3,200 — usually more than a custom build would have cost outright, and you still do not own the site at the end.
Nobody lies to you to get there. That is what makes website builder costs so easy to underestimate.
Advertised monthly price fifteen pounds. Typical month twenty-four reality seventy-two pounds. Three-year running total two thousand six hundred pounds. Asset value retained at the end, zero.
The bait is real, and it works
You have seen the adverts. On the Tube, on YouTube, in your LinkedIn feed. Build a professional website in an afternoon, from £12 a month, no coding needed.
For a UK owner juggling rota gaps, energy bills and a VAT return, that is not a silly offer. It is a rational one. The platform works. The templates look fine. You will have something live by Friday. We are not going to pretend otherwise, because the pretending is what makes most articles on website builder costs useless.
The problem starts around month six, and it is structural rather than dishonest. Wix and Squarespace are publicly listed companies. Their shareholders are not funded by £15 a month. Their model needs the base plan to be a doorway, not a product — so the doorway is deliberately just short of useful for a real trading business.

Layer one: the app marketplace tax
The base tier gives you a homepage, a contact form and a blog. Fine for a portfolio. Now try to actually trade.
You want online booking with deposits and reminders. The native tool is free but capped, so you buy the proper one. You want to control your title tags and schema properly, so you buy an SEO add-on that mostly gives you generic advice. You want a second language for European customers, and the built-in translator breaks your layout. Each decision is small and each one is reasonable. Together they are where website builder costs stop being a subscription and start being a stack.
| What you add | Wix | Squarespace |
|---|---|---|
| Base plan | £16/mo | £16/mo |
| Advanced bookings and reminders | £19/mo | £14/mo (Acuity) |
| Premium SEO tooling | £9.50/mo | £10–15/mo (third party) |
| Commerce tier upgrade | tier bump | £26/mo |
| Running monthly | ~£55 | ~£56 |
Roughly £660 a year in apps alone, and that is before the base fee. Website builder costs are almost always quoted without this layer. Over three years that is close to £2,000, and none of it buys you anything you can take with you.

Layer two: the cut taken from every sale
This is the layer owners genuinely do not see coming, because it does not appear on the subscription invoice at all. It comes out of revenue.
Squarespace applies a 3% transaction fee on its lower commerce plans, which drops away only when you move up a tier. Wix charges its own percentage plus a per-transaction fee until you reach the higher plans. These sit on top of your Stripe or PayPal fees, not instead of them.
Run the arithmetic on a shop turning £5,000 a month. A 3% platform cut is £150 monthly, or £1,800 a year, purely for the privilege of processing on their infrastructure. That single line usually exceeds the entire subscription. Consequently, the businesses hurt most by website builder costs are the ones doing well — growth makes the percentage bite harder, which is a strange thing to design into a platform you are meant to grow on.
A real example, three years long
A beauty salon in Manchester came to us after two years on Wix. They started at £16 a month and were happy with it. By month twenty-four they were paying £72 — bookings app, Instagram feed integration, an SEO add-on, and a tier bump to stop the transaction fee on deposits.
Nothing had gone wrong. No mis-selling, no upgrade they were tricked into. They simply grew, and each time they grew the platform asked for more. That is the whole mechanism, and it is why arguing about the headline price misses the point entirely.
The cost nobody invoices you for
Here is the part we care about most, and it rarely appears in any comparison of website builder costs. You cannot put it on an invoice line, so it goes unmeasured.
Builder platforms ship a lot of code you did not ask for. Every app you install adds its own scripts. The page has to work inside a visual editor, so the markup carries layout scaffolding that a hand-built page simply does not need. On a desktop with fibre, none of this shows. On a phone on patchy 4G somewhere between Leeds and nowhere, it shows badly.
Typical mobile load times observed across our own migration projects. Your figures will vary with content and imagery.
Builder site with five apps loads in 4.1 seconds. Builder base template, 2.8 seconds. Custom self-hosted build, 1.3 seconds.

Speed is a ranking input and, more importantly, a conversion input. It belongs in any honest account of website builder costs. A local searcher comparing three plumbers does not wait. They tap back. You never see that visit, so you never attribute the loss to your platform — which is precisely why this cost survives budget reviews that kill much smaller line items.
Layer three: you are a tenant, not an owner
Ask a builder platform for your site files. You will not get them, and this is the least discussed part of website builder costs.
You can export your written content and your product list. The design, the templates, the page structure and the app configuration stay behind. Leaving therefore means rebuilding from scratch, which is a real cost measured in weeks — and it is the reason so many owners stay somewhere they have already decided is wrong for them.
Compare that with a self-hosted WordPress build. Your files sit on hosting you chose, under a domain you control, in a format any developer on earth can pick up. If we annoy you, you take the site and go. We think that is how it should work, and we would rather compete on whether the work is good than on whether leaving is painful.
Website builder costs against a one-off build
Now the comparison that matters. Three years, everything included, for a typical UK service business with bookings and a small shop.
| Line | Builder route | Custom self-hosted |
|---|---|---|
| Build fee | £0 | One-off project cost |
| Platform and apps, 36 months | ~£2,000 | £0 |
| Hosting and domain, 36 months | included | ~£350 |
| Transaction cuts on £5k/mo | up to £5,400 | £0 above your payment processor |
| You own the site | No | Yes |
| Cost to leave | Full rebuild | Move the files |
The transaction row is the one that decides it for anyone selling online. For a purely brochure site with no bookings and no shop, the honest answer is different — a builder may genuinely be the right call, and we will tell you so if you ask us.
If you want the underlying numbers in more depth, our breakdown of website design costs in the UK covers what a one-off build actually involves, and website builder versus web designer works through the decision itself rather than just the money.
Year by year: how website builder costs actually climb
The climb is never a jump. Every step feels proportionate at the moment you take it, which is why owners rarely notice until an accountant asks what the recurring charges are for.
| Stage | What triggers it | Monthly total |
|---|---|---|
| Month 1 | Base plan, template chosen, five pages live | £16 |
| Month 4 | Customers ask to book online rather than phone | £35 |
| Month 9 | You notice you rank for nothing, so an SEO add-on goes in | £45 |
| Month 14 | First product sold online, commerce tier required | £61 |
| Month 24 | Reviews widget, feed integration, storage upgrade | £72 |
Look at the triggers rather than the numbers. Not one of them is a mistake. Each is a business doing better than it was three months earlier and reaching for the obvious tool. That is what makes website builder costs so hard to argue about in the abstract — the spending is a symptom of growth, and stopping it feels like refusing to grow.
The escape point sits somewhere around month nine in our experience. Before that, migrating means abandoning a site you have barely used. Much later, you have years of content and habits tangled into the platform. Around the nine-month mark you have enough clarity about what you actually need, and little enough sunk cost to move without pain.
What a migration off a builder involves
Owners imagine this is the hard part. It is usually the easiest part of the whole exercise, and knowing the steps takes most of the fear out of comparing website builder costs against a one-off build.
First, every existing URL gets listed and mapped to its replacement. This single spreadsheet is the difference between a smooth move and a traffic collapse, so it happens before anything is designed. Second, content comes across — text, images, products — which platforms do let you export even when they keep the design. Third, the new build goes up on a staging domain where you can break things safely.
Launch day is the redirect switch and a DNS change. Afterwards, rankings typically dip for a fortnight while Google re-crawls, then recover. Where sites end up faster than before, they often recover higher than before. We schedule launches for a Tuesday morning, incidentally, because if something needs fixing you want a full working week ahead of you rather than a Friday evening and a silent inbox.
Three to five weeks is normal for a small business site. Most of that is you approving content, not us writing code. Our step-by-step guide to migrate Wix to WordPress walks through the whole process.
When a builder is genuinely the right choice
We would lose credibility pretending the answer is always custom. It is not.
Stay on a builder if you are testing an idea and might close it in six months. It also makes sense when your site is four pages of information with no bookings, no shop and no ambition to rank beyond your own business name. The same goes if nobody in your business will ever log in to change anything, and the annual cost genuinely stops at the base tier.
Move if you take money through the site. The case gets stronger the more local search matters to how customers find you. And move once your monthly total has passed £40, because it will not come back down. Meanwhile, if you are not sure which side of the line you sit on, add up last month’s actual charges rather than the plan you think you are on — that number is usually the whole argument.
Can I move my Wix site to WordPress without losing rankings?
Yes, provided you map every old URL to its new one with 301 redirects before launch. Rankings usually wobble for two to four weeks and then settle, often higher because the new site loads faster. Skipping the redirect map is what causes the horror stories.
Are website builder costs cheaper for a very small business?
For a genuine one-page brochure with no transactions, yes. The maths only turns against you once you add bookings, a shop, or serious local SEO ambitions. Below roughly £25 a month all-in, staying put is defensible.
Does Squarespace really charge 3% on top of Stripe?
On its lower commerce tiers, yes, and it is separate from your payment processor’s own fee. Moving up a tier removes it. Whether the upgrade is cheaper than the percentage depends entirely on your monthly turnover.
What does a custom build actually cost in the UK?
Small business projects typically land in the low thousands as a one-off, plus hosting of roughly £100 a year. The comparison worth making is not build fee versus monthly fee, but total three-year spend against what you own at the end.
Will I need a developer every time I change a word?
No, and if an agency builds you something that requires it, that is a warning sign. A properly built WordPress site lets you edit text, swap images and publish posts yourself. Structural changes need help. Everyday edits should not.
How long does migrating off a builder take?
For a typical small business site, three to five weeks from brief to launch. Most of that is content and redirect mapping rather than build time. Sites with large product catalogues take longer.
The three questions that settle it
Skip the feature comparisons. Three questions decide this, and they take about a minute.
Does money change hands on your site? If yes, the transaction percentage will eventually dwarf everything else in your website builder costs. That alone usually settles it for shops and any service taking deposits.
Do you need to be found by people who do not know your name? Ranking for a category term rather than your brand needs technical control the platforms restrict. Booking a table at a restaurant somebody already chose is a different problem from being the restaurant they choose.
Would losing the site tomorrow hurt? If the honest answer is not much, rent it. If your bookings, your enquiries and your reputation run through it, owning it stops being an ideological point and becomes basic risk management. Businesses insure their van without thinking. The website usually books more revenue than the van.
Two yeses and you have your answer. One yes and it is genuinely a judgement call, in which case add up the invoices and let the number decide. Our guide to affordable web design for small businesses covers what the alternative actually costs to build and run.
What we would do in your position
Open your last three platform invoices. Not the plan page — the invoices. Add the app charges and any transaction percentages taken from your sales.
Now multiply by thirty-six. Then ask what that money buys you on the day you leave. If the answer is a content export and a fresh start, you already know what the number means. And if the figure is genuinely small, stay where you are with our blessing — the point of understanding website builder costs is making the decision with the real number in front of you, not being talked out of a platform that suits you fine.
We migrate UK businesses off builders most months, so we are hardly neutral here. But the arithmetic above is yours to check, and we would rather you checked it than took our word for it.
