    Tips for measuring up

    There are two types of built-in microwave you can buy – standard and compact. This is a standard model, which means it’s around 60cm wide. Measure your kitchen space to make sure it’ll fit. Also, you’ll need to check the depth of the space, as built in microwaves vary between 45 and 60cm.

    Built in microwave

    This is the second purchase of this microwave the first one broke after two weeks, this was not an AO purchase the manufacturer were not great at customer service and I wasn't happy with needing two major repairs I returned and was refunded, having so much difficulty finding the right size built-in microwave I have ended up with the same microwave again from AO the customer service I received was outstanding nothing was too much trouble I'm taking a chance on this microwave again and fingers crossed the same faults do not happen again its very stylish and looks lovely in my new kitchen arrived yesterday when the box was opened the plug was on top of the machine not set in the polystyrene as it should have been not fitted yet so fingers crossed All in all you can't beat AO on there customer service and prices I have given five stars for all my purchases and deliveries and they also price match if needed great company and service well done AO.

    Functional but interior on the small side given outer size

    Admirably simple controls, decent-looking, but interior and turntable rather small given the exterior dimensions of the appliance.

    Brilliant built in microwave

    Brilliant, easy to use built in microwave. Love the soft opening mechanism. Love how easy it is to set power and time. The only one thing that would improve it would be if it was not so noisy when closing the door. However I still think this is a 5 star product.

    • Connection £37.50

      Get your new oven fitted the same day it’s delivered. Our engineers will disconnect your old appliance before getting your new one set up. We'll give your new appliance a full health check to ensure it’s safe and ready to use straight away. 

    • Remove & Recycle £10.00

      If you’ve bought a new appliance but you don’t want us to connect it for you, all you’ll need to do is disconnect your old one, empty it and place it by the entrance of your property, ready for us to pick up. Or, if you’ve ordered our connection service with a new appliance, we’ll disconnect your old one for you.

      If you haven’t bought a new appliance, we can still collect your old one and take it away for recycling. However, as we won’t be able to come into your home to disconnect it, you’ll need to make sure it’s by the entrance to your property, ready for us to pick up. Our experts will recycle it safely and responsibly in our state-of-the-art facility.

      The cost of our Remove & Recycle service goes towards safely transporting the product to our recycling plant. Under the WEEE regulations, recycling costs are primarily covered by the product manufacturer.

      Also, while we’re picking up your appliance, if you’ve got any smaller kitchen electricals that need recycling – such as kettles, toasters or blenders – we’ll happily take those away too at no extra charge. Just pass them to your driver when we’re picking up your larger appliance.
