Why these picks

  • Ordering is mechanical: customer rating first, then review count, then a stable tie-break. Commission is not an input, and no listing can pay for a position.
  • 0 of the 38 listings carry a customer rating. Unrated listings are not hidden — they sort to the bottom, where you can still see them.
  • No brand quota is applied. Abus holds 8 of the 38 places because that is what the catalogue contains, not because it was favoured.
  • Prices and availability were last read from Amazon UK on 2026-11-01; 30 of the 38 were in stock at that point. Always check the live page before buying.
  • Fit and retention-system adjustability matter more than headline weight or vent count — a lighter helmet that doesn't fit correctly is the worse choice.
  • Ventilation level should match how and where you ride: high-vent designs suit road riding and summer, fuller coverage suits commuting, winter or off-road use.
  • An additional rotational-impact liner, where fitted, adds cost and weight for a small extra margin of protection — worth weighing against budget and riding style rather than assuming it's essential.
  • A removable, washable liner pad makes a helmet meaningfully easier to keep comfortable and hygienic over years of use.

Buying guide

What to look for

Fit protects you, not the spec sheet

A helmet only works if it sits level and snug, low on the forehead, and doesn't rock side to side or front to back once the straps are fastened. Two helmets built to the same internal standard can protect very differently on the same head purely because of fit — check the retention system's adjustment range against your head circumference before looking at anything else.

The foam liner absorbs impact once, then it's done

The crushable foam inside the shell protects by compressing permanently on impact, which is also why a helmet that's taken a real knock needs replacing even if the outer shell looks undamaged — the foam can be crushed invisibly under an intact-looking shell.

Ventilation and coverage trade off against each other

More vents mean a cooler ride but less shell coverage and often a lighter overall build; more coverage suits commuting, winter riding or off-road use where the extra material and lower vent count matter less than durability and weather protection.

Rotational-impact liners are an added extra, not a different category

Some helmets include an additional slip-plane layer inside the shell, designed to let the helmet move slightly independently of the head in an angled impact and reduce rotational force. It typically adds cost and a little weight; it sits on top of, not instead of, a properly fitted helmet.

Price mostly buys comfort and finish, not a different safety tier

Every helmet legally sold for cycling in the UK has to meet the same baseline safety requirement, so spending more mainly buys lighter materials, more ventilation, an easier-to-adjust retention system and additional impact-liner technology rather than a fundamentally different level of protection at the low end.

Common mistakes

  • Choosing a helmet mainly on colour or styling and skipping the fit check — a loose or badly adjusted helmet doesn't sit correctly in an impact regardless of how well-reviewed the model is.
  • Continuing to use a helmet after a crash because the shell 'looks fine'. The foam liner can be crushed invisibly under an undamaged-looking shell and won't protect the same way twice.
  • Buying a child's helmet a size up 'to grow into'. An oversized helmet sits loosely and can shift or tip forward in normal riding, let alone an impact — fit the child now and replace it as they grow instead.
  • Assuming the most expensive helmet on the shelf is meaningfully safer than a budget one. Every helmet legally sold for cycling in the UK meets the same baseline requirement; the extra spend is mostly weight, ventilation and finish.

Standards to look for: Look for BS EN 1078 certification — it's the baseline safety standard every helmet legally sold for cycling use in the UK has to meet, so its presence isn't a mark of a 'better' helmet, but its absence on an unfamiliar or third-party listing is worth checking before buying..

Frequently asked questions

How much do cycling helmets under £100 cost in the UK?
The 38 cycling helmets under £100 on this page run from £5.99 to £97.99, averaging £34.17. Half of them are listed at or below £21.99. Amazon UK prices move, so treat these as the figures at the last catalogue refresh rather than today's shelf price.
Which brands make cycling helmets under £100?
22 brands appear in this selection: Abus (8), ckorison (2), DmTown (2), EXCLUSKY (2), Favoto (2) and Moplasz (2), plus 16 more. The number in brackets is how many listings each has here, not a ranking of the brands themselves.
How many cycling helmets are under £100?
38 of the 40 cycling helmets we list — about 95%. Everything outside that 95% is still on the main cycling helmets page; this page is a filtered view of it, not a separate catalogue.
How do I know if a cycling helmet actually fits?
It should sit level and low on your forehead (not tipped back), stay snug without pinching when the retention dial or straps are adjusted, and not rock forward, backward or side to side when you shake your head with the strap fastened. The chin strap should feel secure but still let you talk and swallow comfortably — too loose and the helmet can shift in a fall, too tight and you'll want to stop wearing it.
Do I really need to replace a helmet after a crash if it looks undamaged?
Generally yes. The foam liner protects by crushing on impact, and that crushing can happen in a way that isn't visible from the outside — an intact-looking shell can be sitting over foam that's already done its one job. If your helmet has taken a real impact, it's honest to treat it as used up rather than relying on a visual check alone.
How often should I replace a helmet that's never been in a crash?
No single reliable figure is sourced here, so treat it as condition-based rather than working to a fixed age: check for cracks, a shell that's gone brittle or faded, straps that have frayed or lost elasticity, or foam that feels compressed or crumbly. General wear, UV exposure and heat (like being left in a hot car) all degrade the materials over time even without a crash.
