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.
  • 19 of the 21 listings carry a customer rating. Unrated listings are not hidden — they sort to the bottom, where you can still see them.
  • The selection carries 13,301 customer reviews in total, the most-reviewed being the Asics Dumbbells Classic with 3,398.
  • No brand quota is applied. Adidas holds 2 of the 21 places because that is what the catalogue contains, not because it was favoured.
  • Prices and availability were last read from Amazon UK on 2026-09-05; 19 of the 21 were in stock at that point. Always check the live page before buying.

How much do dumbbells under £100 cost in the UK?
The 21 dumbbells under £100 on this page run from £9.99 to £90.99, averaging £37.61. Half of them are listed at or below £28.49. Amazon UK prices move, so treat these as the figures at the last catalogue refresh rather than today's shelf price.

17 brands appear in this selection: Adidas (2), Gelert (2), Muc-Off (2), Polar (2), Asics (1) and Dunlop (1), plus 11 more. The number in brackets is how many listings each has here, not a ranking of the brands themselves.
Which of these dumbbells under £100 is rated highest?
The Asics Dumbbells Classic, at 4.5 out of 5 from 3,398 reviews. It is top of this list because of that rating, not because of an editorial pick. 1 of the 21 listings is rated 4.5 or better.
Are the more expensive dumbbells under £100 rated better?
In this selection the cheaper half averages 4.1 out of 5 and the dearer half 3.8, a gap of 0.3 so the cheaper half actually rates better here. That describes these 21 listings only — it is not a rule about dumbbells in general.

21 of the 30 dumbbells we list — about 70%. Everything outside that 70% is still on the main dumbbells page; this page is a filtered view of it, not a separate catalogue.
