Hob Top Blanket Insulation Upgrade for Aga cookers

These pre-cut sections of advanced mineral wool insulation are suitable for most Aga range cookers (you will need to cut the holes for the hotplates) but those with full width rear shrouds are more complex; send us a pic first if you have these.

As a rule of thumb, the older your cooker the more confident at DIY you'll need to be to do this job. Post 74 'Deluxe' cookers are easy, pre-74 cookers can present the odd issue and 'Standards' can be a challenge. 

Send us a pic of your cooker before ordering if you are not sure about anything!

Unfortunately we are unable to ship this product to destinations outside of the UK.

Drawing of Matthew from Blake & Bull - our range cooker expert"Improving your cookers efficiency is about stopping heat leaving from places it shouldn't! Big air gaps under the hob mean heat can escape sideways. This isn't a 5 minute job but is doable with patience and a little help on the phone from us!" Matthew{more about our friendly team}
