Choosing the best eco washing-up liquid comes down to what matters most in your kitchen. Bio-D Fragrance Free is our strongest all-rounder, Miniml Refreshing Apple is a good fit if refill options are your priority, and Faith in Nature Lemon is the one to choose if you prefer a scented formula.
To help you decide, we looked at each product’s ingredients, packaging, refill options, certifications, UK availability and value. It’s also worth remembering that “eco” can mean different things: terms such as “natural”, “plant-based” and “biodegradable” refer to different parts of a product, so they shouldn’t be treated as interchangeable.

Best Overall — Bio-D Fragrance Free Washing Up Liquid
Bio-D Fragrance Free earns Best Overall because it combines practical everyday cleaning with a clear set of household-friendly credentials. The formula contains no added fragrance, making it a sensible choice for people who prefer to avoid scented washing-up products.
It is made in the UK, is Allergy UK accredited and is available through refill options. The 750ml bottle is made from 100% recycled HDPE, while packaging differs across the larger refill formats.
The main limitation is that fragrance-free products will not appeal to everyone. If you prefer a noticeable citrus scent while washing up, Faith in Nature Lemon is likely to be a better fit. For most households, however, Bio-D offers the most balanced combination of practical features, availability, refill options and verified credentials.

Best for Refilling — Miniml Refreshing Apple Washing Up Liquid
Miniml Refreshing Apple stands out because its refill system is central to the product rather than an afterthought. The company offers a return-and-reuse approach for suitable containers, helping households reduce their reliance on buying a new bottle each time they run out. A 5L refill is also available, which can reduce packaging per quantity of washing-up liquid, provided you have enough storage space and will use the product efficiently.
The 400ml washing-up liquid is made in the UK, with 99.65% natural-origin content and 100% natural-origin fragrance. Miniml also states that the product is vegan and cruelty-free. Its refill packaging can be returned for cleaning and reuse, although availability and delivery arrangements may vary.
Miniml is particularly appealing to people who already use refill shops or are willing to organise regular bulk purchases. Its main drawback is convenience: return schemes, delivery arrangements and local availability may be less straightforward than buying a standard bottle from a supermarket.

Best Scented Option — Faith in Nature Lemon Washing Up Liquid
Faith in Nature Lemon is the strongest choice for shoppers who want a scented eco washing-up liquid. Its lemon and citrus fragrance gives it a fresh, familiar feel, while the brand highlights plant-derived cleaning ingredients and vegan credentials.
The product is made in the UK and is available in 1L, 2.5L and 5L formats, which can be useful for busy households or anyone trying to reduce the number of small bottles they buy. The 2.5L refill is currently made from virgin HDPE, so packaging can differ between standard bottles and larger formats. Check the individual product listing before assuming that every size uses the same container or refill arrangement.
It is a practical option for routine washing up and is likely to appeal to existing Faith in Nature customers who want to keep their household products within the same range. The main limitation is the fragrance itself: even a naturally derived scent may not suit people who prefer fragrance-free products or who are sensitive to perfumed household items.

How to Choose an Eco Washing-Up Liquid
Packaging
Refillable bottles can be reused, while recyclable packaging is usually processed after one use. Concentrates and larger refills may reduce packaging per wash.
“Plastic-free” is not automatically better. Consider how long the container lasts, whether it can be reused and how easily it can be recycled.
Fragrance
Fragrance-free products suit households avoiding perfume. Lemon and citrus options may feel fresher, but natural fragrance and essential oils can still irritate. Where relevant, look for recognised accreditation such as Allergy UK.
Ingredients and Performance
“Plant-based” and “natural” do not automatically mean biodegradable. Check specific manufacturer claims, dosage guidance and concentration. A product that needs large amounts or repeated washing may offer poor value.
Certifications and Claims
Look for:
- Allergy UK accreditation, where relevant
- Vegan or cruelty-free certification
- Independent environmental certification
- Clear packaging and refill information
- Specific, verifiable claims
- Dosage guidance
Precise claims are easier to assess than vague terms such as “pure” or “eco-friendly”.
Are Eco Washing-Up Liquids Actually Better for the Environment?
They can be, but the label alone is no guarantee. Concentrated formulas, refill systems and larger formats may reduce product or packaging per wash, but the overall impact also depends on ingredients, manufacturing, transport and how efficiently the product is used.
Using the recommended dosage, reusing a dispenser and choosing a suitable refill can make a meaningful difference. Overall, the most useful approach is to choose a washing-up liquid that performs well at the recommended dose and uses a packaging or refill system you can realistically maintain. Clear, verifiable claims matter more than any single “eco” label on the bottle.
