Insulation upgrade kit for use with Aga range cookers

  • This is everything you need to give your Aga range cooker an under hob insulation a top up and renewal. It's approx 50 litres of vermiculite to top up the loose layer along with a pre-cut section of advanced mineral wool insulation to replace your old 'top blanket'.

    The kit will fit almost any cooker (inc 4 ovens; the main section is identical to a 2 oven) 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!      

    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}
