Allow to cool before bedtime use and do not use on broken skin unless the maker says so.

Wheat bags mould to the body and often include lavender. Gel packs can usually go hot or cold as labelled.
Replace wheat bags if they smell burnt or the fabric wears through.

How we chose these picks
We only included products that were in stock on Amazon UK with a single live buy-box price in pounds when we checked on 27 October 2026, read with a UK delivery address. We skipped listings showing low stock, no stock line or unclear details, and we avoided repeating products already featured in our other guides. Specs in the comparison table come from each product's Amazon UK listing, and a dash means the listing does not state that detail. Descriptions are based on what each listing says; we have not tested these products ourselves, and we have not used star ratings or review counts.

Frequently asked questions
Are microwave heat packs safe?
When you follow the maker’s microwave times and never overheat them, they are a common home comfort product. Check for damage, keep away from unsupervised children, and stop if the pack feels too hot.
What are microwave heat packs made of?
Many use wheat or other grains in a fabric cover; some use mineral beads or gel. Covers may be cotton or fleece. Check the listing for fill and cover materials.
What is in a microwave heat pack?
Typically a fabric shell filled with wheat, flax, clay beads or gel that holds heat after microwaving. Some add dried lavender for scent.
How long to microwave heat pack?
Only as long as the product instructions say — often from about 30 seconds up to a couple of minutes depending on wattage and pack size. If unsure, heat in short bursts and check.
