How do I use a HeatMate promo code?
Select “Show code” on this page and copy the code, add your items to the bag at HeatMate, and paste the code into the promo or discount field at checkout before you pay. The order total should update straight away; if it does not, the code does not apply to your basket.
Why did my HeatMate code not work?
The usual reasons are an expired code, sale items that are excluded, a minimum spend that has not been reached, or a code limited to first orders. Codes marked “Verified” were accepted at checkout on the date shown; unverified codes are listed as found and may already have ended.
Codes are collected from public sources and re-checked on a rolling schedule; retailers can end an offer at any time. InfluencerRate may earn a commission when you shop through links on this page.
