Verdict
All five of these picks are genuinely eco-friendly. In fact, some are setting the benchmark for what sustainable dishwashing should look like. The only real drawback is reach for some, two of these are imports from mainland Europe, which limits the ability to offer closed-loop refill systems in the UK. But performance? These tablets go head-to-head with premium non-eco brands—and win.
Our top three choices, Claro, Marcel’s and Bio -D, have exceptional scores across every category. With Claro offers standout value at just 16p per wash.
These are true contenders—not just for eco buyers, but for anyone who wants performance without compromise. When eco tablets clean just as well (or better) and cost less than big names like Finish or Fairy, the question becomes: why wouldn’t you switch?

FAQs
Do eco-friendly dishwasher tablets really clean as well as mainstream ones?
Yes — the best eco-friendly tablets now match or even outperform many mainstream brands. In our rankings, tablets like Mack and Homethings scored exceptionally high for cleaning power, holding their own against Finish and Fairy. There’s no longer a quality gap — just a choice about ingredients and packaging.
Can I use eco dishwasher tablets in any dishwasher?
Yes, all of the products we recommend are compatible with standard UK dishwashers. Just make sure you’re loading correctly and using rinse aid if needed — especially with eco formulas, as they tend to avoid harsher rinse agents found in mainstream brands.
