Two high-energy foods, two different feeding styles
Fat balls and suet blocks both deliver concentrated energy to garden birds, but they are not interchangeable. The supplied records show differences in ingredients, format and how you present them. Walter Harrisons Fat Balls are a seed-and-fat mix in a ball shape, while Suet to Go Insect Blocks are beef suet with dried insects in a block format. Your choice comes down to which birds you want to attract, how you feed, and the season.
What each product is made of
- Walter Harrisons Fat Balls 85g Value Box of 50: Ingredients are cereals, fats and oils (19%), seeds (8%) and minerals. Nutritional values are fat 18%, protein 9%, fibre 4.0% and ash 9.5%, with an energy equivalent of 406 Kcal/100g. The seed content gives birds something to pick at as well as fat.
- Suet to Go Block Insect Value Box 10x280g: The supplied record describes high-energy beef suet and dried insects. Detailed ingredient percentages and full nutritional values are not included in the supplied information, so compare those from the packaging if you need exact figures.
Walter Harrisons Fat Balls: seed-based energy
- Walter Harrisons Fat Balls 85g Value Box of 50: Suitable for feeding from feeders, table and the ground. You can use fat balls with a hanging feeder, a bird table or directly on the ground, so they suit most garden setups.
Walter Harrisons Fat Balls 85g Value Box of 50 - Walter Harrisons Fat Balls 85g Value Box of 50: This feed will attract Blackbirds, House Sparrows, Coal Tits, Chaffinches, Blue Tits, Great Tits, Dunnocks, Goldfinches, Robins, Thrushes, Woodpeckers and Greenfinches. The listed species give you a realistic expectation of which garden birds the seed-and-fat mix is intended to draw.
Suet to Go Insect Blocks: suet and insect formula
- Suet to Go Block Insect Value Box 10x280g: The non-melting formula ensures they are easy to handle whatever the weather. If you have had fat products soften or become messy in mild weather, this is a practical advantage for year-round feeding.
Suet to Go Block Insect Value Box 10x280g - Suet to Go Block Insect Value Box 10x280g: Feed from a suet block feeder or place directly on a bird table. These blocks are designed for a block feeder or bird table rather than ground feeding, so check your setup before buying.
When to feed suet blocks and when fat balls make more sense
The Suet to Go record says the blocks are appreciated all year round and highlights spring for nurturing young and winter for keeping warm. That makes them a reasonable default if you want one product that works across seasons, especially if you already have a suet block feeder or bird table.
Fat balls are the more flexible option for ground feeding and hanging feeders. The seed content may appeal to a broader mix of birds, and the listed species include ground feeders such as Blackbirds, Dunnocks and Thrushes alongside tits and finches. If you feed on a lawn or table and want to attract a varied crowd, start here.
Practical checks before you buy
- Check your feeder type: Fat balls suit hanging feeders, tables and ground feeding. Suet blocks are intended for a suet block feeder or bird table. If you only have a hanging seed feeder, fat balls are the easier fit.
- Match the season: Both are high-energy foods. The Suet to Go record specifically mentions spring and winter use, while fat balls have no seasonal restriction in the supplied information.
- Consider the birds you see: The fat ball record lists a wide range of garden birds. The suet block record does not list specific species, so if attracting particular birds matters, the fat ball list gives you more to go on.
- Compare pack sizes against your feeding rate: Fat balls come as a box of 50 at 85g each. Suet blocks come as 10 blocks at 280g each. The right choice depends on how many birds you feed and how often you refill.
What the supplied information does not settle
Neither record includes feeding amounts, refill frequency or specific care instructions beyond the feeding locations above. The Suet to Go record also does not provide full ingredient percentages or a complete nutritional breakdown. Use the packaging for exact figures and follow its guidance rather than relying on general advice. If you need a single recommendation: choose fat balls for flexible placement and a broad bird mix, and choose suet blocks for a non-melting, insect-based option suited to a block feeder or table.
