Best Glass Food Storage Containers UK (2026): Lids Checked

Our picks at a glance

Prices checked on UK brand or retailer pages in October 2026.

How we chose

Almost every "glass" food container has a lid made of something else. So we checked three things on each UK listing: the base material (borosilicate or soda-lime glass), the lid material, and the seal. We ranked all-glass lids highest, then bamboo or steel, then plastic, and we said so whenever a brand did not state the lid material. We also checked heat ratings, because the main reason to use glass is reheating without plastic. No container here has independent migration testing; glass is graded "moderate" because it is a well-understood, inert material, and sets with unstated or plastic lids are graded "limited".

Why choose glass over plastic for food storage?

• Glass is inert. It does not contain plasticisers or bisphenols and does not absorb fats, stains or smells.
• Heat changes plastics. A Nature Food study found polypropylene baby bottles released up to 16.2 million microplastic particles per litre, with hot water and sterilisation significantly increasing release (Li et al., 2020). Polypropylene is one of the most common plastic tub materials.
• Bisphenols are being phased out. The EU has adopted rules restricting bisphenol A (BPA) and related bisphenols in food contact materials (Regulation (EU) 2024/3190). "BPA-free" plastic is already common in the UK, but it still sheds particles when heated.

Plastic tubs used cold for dry food are low concern. The clearest win from glass is when you reheat, microwave or store hot, fatty or acidic food.

Borosilicate or soda-lime glass?

Pyrex rates its borosilicate dishes to the EN 1183 thermal shock test, from a minus 20°C freezer to a 200°C oven. Kilner advises against pouring boiling water directly into its soda-lime jars.

What about the lids and seals?

Lids are where plastic hides. Your food rarely touches the lid if you do not overfill and you store containers upright, so a plastic lid matters most when you microwave with it on. Seals are usually silicone or rubber. Germany's BfR sets a recommended limit of 0.5% volatile organic compounds for food-contact silicone (BfR Recommendation XV), and studies show siloxane migration is higher into fatty foods (Zhang et al., 2012). A removable seal is a plus: you can wash it properly and replace it.

The best glass food storage containers in the UK

Pyrex Zero Plastic Rectangular Storage Box: best overall

Both the dish and the lid are borosilicate glass, made in France, with a removable silicone seal for an airtight fit. Take the seal out and the whole thing can go in the oven. Caveat: the seal is silicone and touches food at the rim if overfilled, and glass lids are heavy.

Pyrex Zero Plastic Set of 3 Storage Dishes with Glass Lids: best set

Three all-glass dishes that stack without handles, for batch cooks. Caveat: Pyrex sells several Zero Plastic sets at different sizes and prices, so check capacities before ordering.

Kilner Clip Top Round Jar 2 Litre: best jar and budget pick

Glass jar and glass lid with a stainless steel clip, so only the rubber seal is not glass. Ideal for dry goods, pickles and refills. Caveat: soda-lime glass is less tolerant of sudden heat, and the seal rubber type is not specified.

Lakeland Cook, Store & Serve 3-Piece Set: oven-to-fridge nesting set

Borosilicate bases in 700ml, 1.4L and 2.6L that go from oven to freezer and nest when empty. Caveat: Lakeland does not state the lid material and says lids cannot go in the microwave or oven, which suggests plastic.

Ooni Stack Glass Bowls: best for prep and proving

Three glass bowls stack under one bamboo lid, so no plastic lid or cling film is needed. Caveat: not airtight or leakproof, the bamboo lid is hand wash only, and the glass type is not stated.

Tatay Cook and Eat Glass Set of 3: cheapest glass bases

Three oven-proof glass containers (to 240°C) for about £12. Caveat: the clip lids are plastic with a silicone valve; never heat with the lid on.

Glass or stainless steel for food storage?

Both are inert enough for everyday storage, and the choice is mostly practical. Glass lets you see what is inside, goes in the microwave and oven, and does not react with acidic foods like tomato sauce or pickles. Stainless steel is lighter and unbreakable, which makes it better for packed lunches and children, but it cannot go in the microwave and very acidic foods are better kept in glass for long periods. Many households use glass at home and steel for lunches on the go. See our guide to stainless steel lunch boxes for steel options.

How much should you spend?

You do not need to replace everything at once. Start with the containers you reheat in, because heat is when plastic matters most. A single all-glass Pyrex box costs about £20, and Kilner jars cost under £10 each for dry goods. Keep existing plastic tubs for cold, dry items like pasta or snacks, and replace them as they wear out.

How to use glass containers well

• Let hot food cool a little before sealing, and do not move glass straight from freezer to a hot oven unless it is rated for it.
• Reheat with the lid off, or with a plate on top, if the lid is plastic.
• Store upright and leave a gap below the lid.
• Replace cracked or chipped glass.
• Wash removable seals separately and replace them when they harden or smell.

What to avoid

• "Glass" sets with no lid information. Ask the retailer or assume plastic.
• Microwaving with plastic lids on, even when labelled BPA-free.
• Decorated drinking jars for hot food, where decoration quality is unknown.
• Using chipped glass. Thermal stress makes chips more likely to crack.

Bottom line

For the most glass and least plastic, the Pyrex Zero Plastic range is the clearest choice in the UK, with glass lids and replaceable silicone seals. Kilner clip top jars are the cheapest all-glass option for dry and cold food. Mixed sets with plastic lids still cut plastic contact a lot if you reheat lid-off and do not overfill.
