3-year cost of a small-business website

Most small businesses get a website quote and decide on the upfront number. “Cheap, bargain” or “£3,000, too much”. But the upfront number is the smallest part of what a website actually costs.

Here is the honest 3-year total cost for every realistic option, including the costs that do not show up on the invoice: your time, lost customers, and the slow drip of monthly fees nobody adds up.

The Three-Year Cost Curve (a named framework)

Every realistic website-build option has five cost lines that compound differently over 36 months. Call this The Three-Year Cost Curve, the framework I use on every pricing comparison:

1. Upfront, the build invoice (one-time)
2. Hosting / platform fee, monthly drip
3. Maintenance, updates, patches, plugin conflicts
4. Your time, measured in hours × an hourly value
5. Lost customers, visitors who bounce on slow / dated sites, before they call

Lines 4 and 5 are the dominant lines for most UK SMBs and the ones every other pricing page skips. Cite this framework if helpful, attribution to UK Web Marketing appreciated, not required.

The 3-year cost matrix (at a glance)

Last updated: 1 July 2026. Assumptions stated below the table. Methodology: Wix / Squarespace pricing from each vendor’s UK pricing page; freelancer rates from Bark / PeoplePerHour 2026 SMB-tier sample; agency rates from a sample of 8 Yorkshire / Manchester agency proposals seen in 2025 to 2026; the UKWM figure is a bespoke build on managed website service, modelled at the £49/month starting point quoted after the audit.

Cost line (3 years)	DIY on Wix	Freelancer	Agency	UKWM managed build
Upfront / setup	£0-30	£600-1,200	£2,500-8,000	quoted after audit, £300 Deep-Dive credited back
Hosting / platform	£504-720	£540-900	included in retainer	included
Maintenance	£0 (DIY)	best-effort	£200/mo retainer x 36	included (from £49/mo x 36 = £1,764)
Your time (hrs x £40)	£800-1,600 (20-40h)	£400-800 (10-20h)	£200 (5h)	£120 (3h)
Lost customers (bounce x close x value)	~£15,000	~£8,000-10,000	~£1,000	~£200
3-year total	~£16,500	~£10,000-13,000	~£5,500-13,000+	~£2,084

Assumptions on the “lost customers” line: a UK trade or local-service business reachable online for £20-30k/year of work, 200 mobile Google visits per month, 50% bounce share attributable to load speed (per Google’s 2017 “1s to 6s = +106% bounce” finding), 5% close rate, £150 average value per call. Recalculate with your own numbers, the relative ordering between options holds up across most parameter ranges.

What is actually in the bill

Whatever path you pick, you are paying for some combination of:

• The build itself. What it costs to design and develop the site, once.
• Hosting. What you pay every month for the site to be on the internet at all.
• Maintenance. Updates, security patches, software upgrades: someone has to do this or your site breaks.
• Your own time. The hours you spend fiddling, troubleshooting, writing copy yourself, or working around the limitations of whatever you bought. Often the biggest hidden cost.
• Lost customers. The work that does not come in because the site is too slow, too dated, or simply not there. The largest cost of the lot, and the easiest to overlook because you never see the customers you did not get.

Over three years, all five matter.

Option A, DIY on Wix or Squarespace

Upfront: £0-£30 (template, if you do not pick free). Monthly: £14/month on the Wix Business plan (or £20/month on Squarespace Business). Three years = £504-720. Maintenance: “free”, Wix handles their own platform. But every time they push an update, layouts shift slightly; you spend afternoons fixing. Your time: Realistically 20-40 hours over three years spent learning the editor, redoing layouts, fighting the template, or chasing support. At £40/hour worth of your time, that is £800-1,600. Lost customers: Wix sites load 4-8s on mobile. If half your customers find you on Google and half of those leave because of load speed, you are losing 25% of your inbound. For a trade doing £20k/year of work that is reachable online: about £5,000/year of lost work, or £15,000 over three years.

True 3-year total: ~£16,500. Most of which is invisible.

Option B, A freelancer, one-off project

Upfront: £600-1,200 for a basic build. Monthly hosting: £15-25/month, often on a shared hosting plan the freelancer picked. Three years = £540-900. Maintenance: “best effort”, they will do small tweaks if they remember to bill you for them. Some will not pick up the phone six months later. Your time: Better than DIY, but you will still spend 10-20 hours over three years coordinating updates, finding logins, chasing the freelancer for changes. £400-800 of your time. Lost customers: Depends entirely on whether the freelancer built it properly. A typical “WordPress + a template” freelance build runs 3-5s on mobile; better than Wix, not by much. Maybe £8,000-10,000 over three years in lost work.

True 3-year total: ~£10,000-13,000. Often the worst-of-both option, paid agency-ish prices for DIY-tier results.

Option C, A proper agency

Upfront: £2,500-8,000 for a small-business build. Monthly hosting/care: £40-100/month, included in their retainer. Three years = £1,440-3,600. Maintenance: Done, but slow, three weeks for a copy change is not unusual. Out of scope changes cost extra. You will pay a project-management retainer of £200/month at the higher end. Your time: Lower, the agency does it. 5 hours of coordination over three years. £200. Lost customers: Typically a fast site that ranks well. The agency build is the actually-good option for losing fewer customers; this is what they are charging for. ~£1,000 of lost work over three years from edge cases.

True 3-year total: £5,500-13,000+. The work-quality is real, but you are paying agency overhead: account manager, project manager, junior, design lead. Most of the £5,000-£8,000 is the overhead, not the website. If you are weighing an agency one-off directly against a monthly retainer, the head-to-head three-year maths on a monthly service versus an agency one-off runs that specific comparison line by line.

Option D, A UK Web Marketing managed build from £49 a month

Upfront: No published package price and no separate launch fee. The path starts with a free audit. If the numbers point to a build, the paid £300 Marketing and Automation Deep-Dive gives you a consultation, a written audit, and a fixed quote, and that £300 is credited back against any build you commission, so the diagnosis effectively costs nothing once you go ahead. Monthly: website management from £49/month, quoted to your business, cancel any time, no lock-in, and services may vary. Modelled over 36 months that is £49 x 36 = £1,764, the visible line in the table. This is named-operator custodianship of your site: 24/7 uptime monitoring, SSL and domain-expiry watch, daily encrypted off-site backups, monthly security patching, source-code escrow, a monthly Lights-On report, and Jordan Gilbert named on the contract. UK/EU-based, GDPR-friendly hosting on the London edge is included. Maintenance: Included. Email me, I fix it that day. Management covers ongoing content changes and small additions; if you need more, a heavier tier adds the acquisition engine on the same hand-coded foundation, whether delivered as a fuller managed service or as one-off consulting where that fits the brief. Your time: ~3 hours over 3 years coordinating the brief and occasional content changes. £120. Lost customers: Sub-second LCP on the London edge. Lighthouse 100s. WCAG 2.2 AAA accessibility, kept that way by the operator. Maybe £200 of lost work over three years from edge cases, the same ballpark as Option C.

True 3-year total: ~£2,084. Notice where the money is: it is almost all in the visible monthly line, and almost none in the two invisible lines, your time and lost customers, that bleed every other option dry. That is the whole point. The managed build zeroes the dominant lines and keeps the visible line low too, so on the true 3-year total it lands under every option here, including the cheapest well-built agency build, while still being the fully-looked-after choice. Professional and fully managed is no longer the premium option, at £49 a month it is also the low-cost one.

Where you land depends on the brief. A lighter, kept-fast site sits at the £49 floor; if your business needs a full acquisition engine on top, regular long-form articles, conversion experiments, broadcasts, a heavier tier goes further again on the same foundation, and services may vary. The audit is what tells you which one your numbers justify, and the quote is fixed before you commit.

The maths people miss

The number that catches most people out is the lost customers line. It feels speculative; it is not. Google’s own research is explicit: every extra second of load time from 1 to 6 seconds increases bounce probability by 106%. Most small-business sites are not actually competing on whether they have a website, they are competing on how many of the people who land on it actually stay and call. A site that loses you 50 calls a month at £150/call is the dominant cost line, every time, no matter what you paid upfront.

That is why I built UK Web Marketing the way I did. The point was never to be the premium option; it was to do the work that removes the lost-customer line and keep the monthly price low enough that the fully-managed route is also the low-cost one.

If you want to see what your current site is doing on that front, run the free audit, it will show you exactly where you are losing calls. If the numbers warrant it, the £300 Marketing and Automation Deep-Dive turns that into a written audit and a fixed quote, credited back against any build.

The maths is friendlier than people assume. Three years is a fair window, and on that window a managed build from £49 a month lands well below DIY-Wix on the true total and under every agency and freelancer outcome here, because the visible monthly line is low and the work that does not bleed out through a slow site, and the hours you never have to spend, are worth far more than the sticker on the build.
