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 43 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. SONGMICS holds 9 of the 43 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; 39 of the 43 were in stock at that point. Always check the live page before buying.
  • The diameter of the handle should comfortably fit your grip size to prevent slippage and allow for smooth movements.
  • The overall length of the dumbbell is relevant if you intend to use them for exercises that require reaching or stretching, such as overhead presses.
  • The weight increments offered within a set will influence the progression of your training. Smaller increments allow for more precise adjustments, while larger ones can be cost-effective.
  • The construction material impacts both durability and ease of movement – heavier materials tend to offer greater stability but may require more effort to lift.

Buying guide

What to look for

Weight Range

The total weight range of dumbbells dictates the variety of exercises you can perform. A wider range allows for more complex movements and targeting different muscle groups, but also increases the overall cost and storage space required. Consider what types of workouts you intend to do – basic strength training or something more advanced – when determining your desired weight range.

Handle Type

The shape and material of the dumbbell handle significantly impact comfort and grip stability. A thicker, textured handle provides a better hold during heavier lifts, while a thinner, smoother one might be preferable for lighter exercises or those requiring more dexterity. The handle's design should complement your chosen exercise style.

Material Durability

The material used in dumbbell construction affects its longevity and resistance to wear. Cast iron dumbbells are exceptionally durable but can be heavy and prone to chipping. Chrome-plated dumbbells offer a lighter weight and improved grip, but may show signs of wear more quickly with frequent use.

Space Requirements

Dumbbells take up storage space, so consider the available area before purchasing. Fixed dumbbells require dedicated shelving or floor space for each weight. Adjustable dumbbells can be stored more compactly, though they still occupy a significant volume when fully extended.

Common mistakes

  • Buying a single set of heavy dumbbells when you need to gradually increase resistance. — Starting with an overly heavy set can lead to poor form, increased risk of injury, and discouragement. Begin with lighter weights and progressively increase the load as your strength improves. Check the weight increments offered.
  • Purchasing adjustable dumbbells without considering the available space. — Adjustable dumbbell sets can take up a considerable amount of floor or storage space when fully extended. Measure your available area carefully before committing to a purchase.
  • Ignoring handle ergonomics. — A poorly designed handle can cause discomfort and reduce grip stability, particularly during heavier lifts. Ensure the handle diameter and shape are comfortable for your hand size and grip style.
  • Assuming all dumbbells are created equal in terms of durability. — The material used significantly impacts the dumbbell's lifespan. Cast iron is exceptionally durable but can be prone to chipping, while chrome-plated versions may show signs of wear more quickly.

How many dumbbells are under £100?
43 of the 46 dumbbells we list — about 93%. Everything outside that 93% is still on the main dumbbells page; this page is a filtered view of it, not a separate catalogue.
What does ‘dual-grip’ mean on a dumbbell set?
‘Dual-grip’ refers to a handle design that allows you to switch between holding the dumbbell with your palm facing up or down. This offers greater versatility for different exercises and can be more comfortable for some users.
Can I use dumbbells with other equipment, like a weight bench?
Yes, dumbbells are commonly used in conjunction with a weight bench to perform a wide range of exercises, such as chest presses and rows. However, ensure the bench is stable enough to support the added load.
How do I clean my dumbbells?
Regularly wipe down your dumbbells with a damp cloth to remove sweat and dirt. For cast iron dumbbells, you can use a mild soap solution if necessary, but always dry thoroughly afterwards.
