No Nonsense Central Heating Inhibited Anti-Freeze 5Ltr
Does as it's name suggests.
I have used this in an air to water heat pump system in a 50/50 mix. The outdoor pipes were exposed to -8C this Winter with no issues and should be ok in much lower temperatures at this mixture ratio.
*hint* keep an empty container so you can leave a quanity on site, mixed at the correct ratio and ready to top up with. DO NOT PUT NEAT ANTIFREEZE IN THE HEADER TANK. You will struggle to make it mix in the system and will end up with cold spots on radiators due to different density of the fluids in the system.

Good value product
Bought online for my house in France based on value for money and Screwfix's reputation for reliable products. Was not disappointed in the product - it did exactly what it said it would do - nor the online purchasing process and service apart from one minor grouse: the insistence on producing the card used to make the purchase. I know it is supposed to be a security measure but surely showing the card is enough; why is it necessary to run through a zero-value transaction? At that stage in the process, I had bought the product because the payment had gone through my bank account, thus the product no longer belonged to Srewfix. I had paid, therefore it was mine. I would like to know what would have happened had I forgotten my card. Would the store have kept the antifreeze even though it was not theirs? Is not that a type of theft? Apart from that, entirely satisfied with the deal.

Reasonably priced but only time will tell as far as performance
