A subscription wins when your website needs to keep changing and nobody in your business wants to own that; a one-off build wins when you have in-house technical help and a site that will genuinely sit still. The deciding factor is not total cost — it is who handles the site in month seven.
The two cost shapes
A one-off project concentrates the spend up front. You pay somewhere between £1,500 and £6,000, the site launches, and the invoice ends. What ends with it is usually the relationship: hosting, updates, security patches and content edits become your problem, or a separate retainer.
A subscription spreads the same work across months and keeps the relationship open. You pay less at the start and more over three years, and in exchange the maintenance never lands on your desk.
Where the one-off build genuinely wins
Be honest about this rather than assuming subscriptions are always better:
- You already have technical help. If someone in the business can handle a hosting migration or a plugin update, you are paying a subscription for labour you already have.
- The content is genuinely static. A single-page site for a business whose prices, services and team do not change can sit untouched for years.
- You want to own the asset outright. Some businesses need the code and the hosting under their own control for reasons that have nothing to do with cost.
Where the subscription wins
- Nobody wants to own the site. This is the most common situation and the most expensive to ignore. Sites that nobody maintains break quietly — expired certificates, outdated contact details, a broken contact form nobody notices for four months.
- Search visibility matters. SEO and AEO are not launch tasks. They are ongoing, and they are the first thing dropped when a site has no owner.
- Cash flow matters more than total cost. For a business that has just started, £49 a month and a working site beats £3,000 and a three-month wait.
The hidden cost of the cheap one-off
The failure mode to watch for is a low-priced project with no maintenance attached. The site launches, looks fine, and then slowly rots. Two years later the honest comparison is not “£2,000 versus £1,176 of subscription” — it is a working site against a broken one, and a rebuild on top of the original invoice.
How to decide in one question
Ask who will update the site in month seven, and get a name. If you have one, a one-off build is reasonable. If the answer is a shrug, you are choosing between a subscription and a site that stops being true.
