Do I save money by building the website myself on Wix or Squarespace?

On the monthly fee, a little — DIY builders start around £13–£17 a month. But you're doing all the work, the sites are slower, and you hit a ceiling the moment you need something the builder won't do. The real cost of a DIY site is the enquiries it doesn't generate because it loads slowly and isn't built to be found. Cheap monthly isn't the same as cheap over three years.

Pay Monthly Website vs One Big Quote: The 3-Year Maths

You’ve got two tabs open. One is me: £49 a month, no upfront cost. The other is a web agency quoting two, three, maybe five grand to build it once and be done. The agency tab looks like the grown-up option — pay once, own it, no more bills. So which actually costs less over the life of the site? Let’s sit down and do the sum.

I’ll do this honestly, including the part where the big quote wins. I’ve sold websites both ways — lump sum upfront from 1998 until I switched in 2020, pay monthly ever since — so I’ve watched both run their course for real businesses. The maths isn’t complicated. It’s just that nobody lays it out next to each other, because the people quoting the big number would rather you didn’t.

”Three years of pay monthly costs less than the cheap agency quote. And someone’s still maintaining the site at month 36.”

The number that looks bigger is usually smaller

Let’s start with the headline figures, because that’s the comparison those two tabs put in front of you.

£49 a month. Over a year that’s £588. Over three years it’s £1,764.

A typical small-business agency build is quoted somewhere between £2,000 and £5,000. Call the cheap end £2,000.

Already the monthly option is the cheaper one over three years, by a couple of hundred quid against the cheapest agency quote and by thousands against a mid-range one. But that’s not even the real gap, because we haven’t started adding up what the agency quote leaves out.

What the big quote doesn’t include

A build price is exactly that: the price to build it. It’s the deposit on the website, not the cost of the website. Three things sit underneath it that rarely make it onto the quote:

Hosting. The site has to live somewhere. After any free first year, that’s typically £100–£200 a year. Over three years, call it £300–£500.

Maintenance. This is the big one. A website isn’t a painting you hang on the wall — it needs updates, security patches, plugin renewals, the occasional fix when something breaks. On a typical WordPress build that’s £50–£100 a month if you pay for it, or “call us for a quote” each time if you don’t. Even at the low end, that’s £1,800 over three years. At the high end it dwarfs the build.

Continuity. The quietest cost of all, and the one nobody prices. It’s whether the person who built it is still answering the phone in eighteen months. Plenty of trades have a beautiful site that’s slowly dying because the developer moved on, went quiet, or simply stopped replying — and now nobody can change the phone number on it without starting again.

The honest three-year sum

	Cheap agency build	Pay monthly (£49)
Upfront	£2,000	£0
Hosting (3 yrs)	£300–£500	included
Maintenance (3 yrs)	£1,800+	included
Updates & changes	extra, or DIY	included
Three-year total	£4,100+	£1,764
Site condition at month 36	three years stale	kept current

The figures aren’t loaded. The agency column is the cheap end of the quote, and the maintenance line is the low end of what maintenance actually costs. The gap only widens with a mid-range quote.

That’s the maths that gets skipped. Not because it’s hard — because the build price and the running costs never appear in the same conversation. One’s a sales quote; the other’s a problem for future-you.

A headline build price that excludes hosting, maintenance and continuity isn’t the cost of the website. It’s the deposit — and the balance is paid in instalments you didn’t agree to.

The bit the monthly fee is really buying

Look at that table again and notice what “included” is doing. The £49 isn’t just spreading the build cost over time like a finance plan. It’s buying the thing the agency quote quietly drops: someone whose job it is to keep the site working after it’s live.

That’s the part that matters for a real business. Your number changes, you add a service, your prices go up, you want a new photo of the van on the homepage — you email me and it’s done. No logging in, no wrestling a page builder at nine at night, no “that’ll be £85 plus VAT, I’ll get to it next week.” When Google moves something, the site moves with it. At month 36 the pay-monthly site is current; the build-it-once site is three years old and nobody’s touched it.

A website that isn’t maintained doesn’t stay the same — it quietly gets worse. The phone number’s wrong, the services list is out of date, the contact form’s been broken for months and you only find out when a customer mentions they tried to get hold of you and couldn’t.

When the big quote actually wins

I said I’d be honest, so here’s where paying upfront genuinely makes more sense — because it sometimes does.

If you’ve got real capacity to run the site yourself — someone in-house who can host it, keep it updated, and fix it when it breaks — then you’re not getting much value from the maintenance half of a monthly fee. You’re paying for a service you could do yourself. In that case, owning it outright is the rational move.

And if what you actually want is to own the asset — the source code and the domain in your own name, from the start, no ongoing relationship with anyone — then upfront is right for you too. But that doesn’t mean a £3,000 agency. With me, owning it outright is the £995 buyout — you get the full source code and the keyword-matched .co.uk transfers into your name. Same ownership a five-figure agency would sell you, for a fraction of the price. So even the “I want to own it” case usually doesn’t point at the big quote. It points at buying out the £49 build.

Quick way to tell which one’s for you

Pay monthly (£49) — you want it built, live, and looked after, without being the one who looks after it. Most trades.
Buy outright (£995) — you want the source code and domain in your own name and you’ve got the capacity to run it, or just prefer to own rather than rent.
The £2,000–£5,000 agency — you need something genuinely bespoke and complex that a starter build can’t do. A real category, but a smaller one than the people selling it would have you believe.

So — pay monthly, or pay once?

If the question is purely “which costs less over three years for a normal small-business website,” the answer is pay monthly, and it’s not close once you count hosting and maintenance honestly. £1,764, everything included, site kept current — against £4,000-odd for a build you then have to feed.

If the question is “I want to own it outright,” the answer still usually isn’t the big agency quote — it’s the £995 buyout, which gets you the same ownership for a fraction of the money. The pricing page lays both options side by side so you can see exactly what £49 a month and £995 outright each include.

The only time the five-figure quote earns its keep is genuine bespoke complexity — and most trade websites aren’t that, however much they’re sold as if they are. What you actually need is a fast, findable site that someone keeps working. The maths just happens to agree.

Common questions

Is a pay monthly website cheaper than paying upfront?

Over three years it’s usually cheaper than the typical agency quote, and the gap widens once you add the things an upfront quote leaves out — hosting, updates and maintenance. £49 a month is £1,764 over three years, all of it including hosting and ongoing work. A £2,000–£5,000 build is just the build; hosting and maintenance sit on top, and the site is three years stale by the end unless you keep paying someone to look after it. Where upfront wins is when you’ve got in-house capacity to maintain it yourself, or you specifically want to own the asset outright — in which case the £995 buyout is the cleaner route, not a five-figure agency.

How much does a pay monthly website cost over three years?

£49 a month is £588 in year one and £1,764 over three years. That figure includes hosting, the SSL certificate, ongoing updates and changes, and a keyword-matched .co.uk domain — there’s nothing to add on top. Add Breakthrough SEO at £330/month only if you want active Google visibility work; the website itself stays £49 whether or not you take it.

What’s not included in a cheap website quote?

Usually three things, and they’re the expensive three. Hosting — often £100–£200 a year after the first. Maintenance — updates, fixes, plugin renewals and security, which on a typical WordPress build runs £50–£100 a month or “call us for a quote”. And continuity — the developer being there in eighteen months when something breaks. A headline build price that excludes all three isn’t the real cost of the website; it’s the deposit.

When is it better to pay upfront for a website?

When you want to own the asset outright and you’ve got the capacity to run it. If you have someone in-house who can host and maintain a site, or you simply want the source code and domain in your own name from the start, paying once makes sense. With me that’s the £995 buyout — you get the full source code and the keyword domain transfers into your name. That’s almost always a better way to own it outright than a £3,000+ agency build, because you get the same ownership for a fraction of the price.

What happens to the cost if I want to leave?

You stop with 30 days notice — no contract to break, no exit penalty. You keep all your content. If you want to keep the exact keyword address and the build, you buy it out once for £995 and it’s yours. There’s no version where leaving costs you more than the notice period plus, if you choose it, the one-off buyout.
