Looking for ways to reduce plastic waste in your kitchen without giving up effective cleaning products? Switching to washing-up liquid refills in the UK is a simple change that can help you use fewer new bottles and build a more sustainable household routine.
Traditional washing-up liquid usually comes in small plastic bottles. While some packaging can be recycled, recycling is not always the most effective way to reduce waste. Reusing a bottle several times and buying larger refills can help reduce the need for new packaging.
Fortunately, UK shoppers have several options, including concentrated washing-up liquids, bulk refill containers, refill cartons and refill stations where you can top up your existing bottle.
In this guide, we explore seven washing-up liquid refill brands worth considering in 2026. We compare their refill formats, sustainability features and suitability for different households so you can find an option that fits your budget and cleaning routine.
Why Choose Washing-Up Liquid Refills?
Switching to refillable washing-up liquid can make everyday kitchen cleaning more resource-conscious.
Here are some potential benefits:
- Less packaging waste: Refilling an existing bottle can reduce the number of new bottles you purchase.
- Better value when buying in bulk: Larger containers can offer a lower cost per litre, although prices vary by brand.
- Convenient storage: Keeping a larger refill container under the sink means you can top up your dispenser when needed.
- Less frequent shopping: Buying a larger quantity may reduce the need to purchase washing-up liquid as often.
- More sustainable habits: Reusing containers encourages a shift away from disposable household products.
However, not every refill system has the same environmental benefits. Consider the packaging material, the amount of product supplied, delivery requirements and whether the packaging can be reused or recycled locally.
1. Faith In Nature Washing-Up Liquid — Best for Bulk Refills
Best for: Families and households that use washing-up liquid regularly.
Faith In Nature is a UK-based brand known for its natural-origin personal-care and household-cleaning products. Its washing-up liquid is available in larger refill containers, including a 5-litre lemon washing-up liquid option.
The brand states that its lemon formula contains 99% biodegradable ingredients and is concentrated to help reduce the amount needed per wash. Its larger container can be useful for households that already have a reusable washing-up liquid bottle.

How to Choose the Best Washing-Up Liquid Refill in the UK
Choosing a refill is not just about finding the largest bottle. Consider these factors before making your decision.
1. Compare the cost per litre
A large container may cost more at checkout but offer better value over time. Divide the total price by the number of litres to compare products fairly.
Also consider how concentrated the formula is. A product that requires less liquid per wash may provide better value even if its bottle price is higher.
2. Look at the refill packaging
Some refill systems use large plastic bottles, others use cartons or pouches, and some allow you to refill a reusable container at a shop.
Think about whether the packaging can be reused, returned or recycled through facilities available to you. A refill is not necessarily plastic-free, but it may still reduce packaging use compared with repeatedly purchasing small bottles.
3. Choose ingredients that suit your household
Read the ingredient list and look for clear information about surfactants, fragrances and biodegradability. If you prefer to avoid added fragrance, choose a product that specifically identifies itself as fragrance-free.
Remember that “natural” does not automatically mean harmless to aquatic life or suitable for every skin type.
4. Check refill availability near you
If you want to refill locally, use the brand’s store locator or contact the shop before visiting. If you live far from a refill station, home-delivered refills or a larger container may be more convenient.
5. Consider storage and ease of use
A large container can be awkward to lift and pour. Choose a size that fits your cupboard and that you can handle safely. Smaller refill cartons may be easier to manage if you have limited storage space.
5 Simple Ways to Reduce Plastic Waste While Washing Up
Switching to refillable washing-up liquid is a useful start. These additional habits can help you reduce waste further.
- Reuse your existing bottle: Keep using a bottle that is in good condition instead of replacing it unnecessarily.
- Use the right amount: Follow the product’s recommended dose rather than squeezing out extra liquid.
- Try a refill station: Where available, refill a suitable container rather than buying a new bottle.
- Store refills carefully: Keep products sealed and follow the manufacturer’s storage and safety instructions.
- Consider a solid washing-up bar: If you want to reduce reliance on liquid refills, a solid bar with minimal packaging is another option.
You do not need to replace every household product at once. Start with the products you use most often and make changes that are practical to maintain.
Final Thoughts
Switching to washing-up liquid refills in the UK is a practical way to reduce your reliance on new plastic bottles without changing your everyday cleaning routine.
Whether you prefer bulk containers from Faith In Nature or Bio-D, local refill stations from Ecover, or the convenience of smol’s home-delivery system, there are several approaches to consider. The right choice will depend on your budget, storage space, local availability and packaging preferences.
Before buying, compare the price per litre, check the refill packaging and choose a product that works well for your household. Reuse your bottle for as long as practical and use only the amount of washing-up liquid you need.
