There’s no rule that says a website needs redoing every three years, or every five, or on any fixed schedule at all. Plenty of well-built sites are still doing their job perfectly a decade in. Plenty of two-year-old sites are already quietly costing their owner customers. The honest answer to “how often” isn’t a number — it’s a handful of signs worth actually checking for, rather than going on a gut feeling that it “looks a bit old.”
Why there’s no fixed interval
A website’s design ages differently depending on what it’s built on and how it was built. A well-designed, custom-built site with clean, simple styling tends to age gracefully — good typography and a clear layout don’t really go out of fashion. A site built entirely around a trendy visual style (a specific font pairing, a colour scheme, an animation style that screamed “current” the year it launched) tends to look dated fast, sometimes within eighteen months, because it was never built to last — it was built to look current.
That’s the real reason there’s no universal number: two sites launched the same week can age at completely different rates depending on what they were designed around.
Signs it’s actually time, not just “feels old”
It doesn’t work properly on a phone. Not “looks slightly cramped” — actually broken. Text overlapping, buttons too small to tap accurately, images that don’t load properly. More than half of local searches happen on mobile; if your site is genuinely broken there, that’s not aesthetics, that’s lost enquiries.
It’s slow, and you can point to why. A site that’s accumulated years of plugins, add-ons, and unoptimised images tends to get slower over time, not faster. If pages take several seconds to load, that’s measurable — not a feeling — and it directly affects both visitors and search rankings.
Your business has changed and the site hasn’t. You’ve added services, changed direction, or started serving different customers, but the site still describes the business you ran three years ago. This is less about design and more about the site no longer being an accurate picture of what you actually do.
You’ve stopped being able to update it yourself. If every small change means calling someone, waiting a week, and paying an invoice for a two-line text edit, the site has become a liability rather than a tool — regardless of how it looks.
You’ve quietly stopped sending people to it. If you find yourself directing people to your Facebook page or Instagram instead of your own website because it’s easier to keep current, that’s a strong, honest signal the website isn’t pulling its weight anymore.
What doesn’t automatically mean it’s time
“Every other site in my industry just redesigned.” Competitors refreshing their sites isn’t itself a reason — plenty of redesigns are driven by a new decision-maker wanting something different, not by the old site actually failing. Worth noticing, not worth reacting to on its own.
A slightly dated-looking but otherwise functional site. If it loads fast, works on mobile, and still gets you enquiries, an aesthetic refresh is a “nice to have,” not urgent. Money spent chasing the newest visual trend has a short shelf life anyway — see above.
One bad comment about the look. A single offhand remark from a customer or supplier is worth noting, not panicking over. Look for a pattern before treating it as a verdict.
Redesign, or repair?
Not every “it’s time” moment needs a full rebuild. If the bones are sound — decent structure, reasonable code, no major mobile-breaking issues — a lot of what’s actually bothering you can often be fixed with updated content, new photos, and a visual refresh rather than starting from scratch. A full redesign makes more sense when the underlying platform itself is the problem: unmaintainable, insecure, or built on something that’s since been discontinued or abandoned by whoever built it.
If you’re weighing that decision properly, it’s worth working through what to actually check before paying for a redesign first — a lot of “I need a redesign” turns out to be “I need better content and a few fixes,” which is a much smaller job.
The honest answer
Check your site against the signs above roughly once a year — not because a year is a magic number, but because it’s a sensible cadence to catch drift before it compounds. If none of the real signs apply, the site’s doing its job; leave it alone and spend your money elsewhere. If two or three do, that’s worth taking seriously, regardless of how long it’s actually been since launch.
