Once you’ve chosen your fridge freezer, you’ll need to register it to receive cashback. You can register it at the Miele site. If you don't already have a Miele account, you'll have to set one up, but it's a simple process.

You must register your purchase by 30 September. Within 28 days of your claim being validated, you’ll receive your cashback by BACS transfer to your nominated bank account.

The offer is open to UK residents only and you can’t use it in conjunction with any other vouchers or deals from Miele itself (although separate deals from retailers are fine).

There are four fridge freezers included in the offer.

The KFN 28132 ws is available from AO.com for £899. It’s an A++ rated 60/40 fridge freezer with a 340-litre capacity, which works out to hold around 18 bags of shopping. That’s 209 litres in the fridge and 95 litres in the freezer. It’s a frost-free appliance, which means you should never have to manually defrost it. Its dimensions are 186.1 x 60 x 65.7cm.

Miele fridge freezer

The Miele KFN 28133D ws 60/40 Frost Free Fridge Freezer is available from Marks Electrical (not related to M&S) for £859, down from £949, but the cashback offer is still available with this product.

It’s A+++ energy rated, with frost-free and dynamic cooling technology. It also has a 340-litre capacity. In essence, it has the same features, capacity and dimensions as the fridge above, but it’s more energy efficient. There aren’t many of this model left, which is presumably why Marks has discounted it.

The KFN 29142 ws can be ordered straight from the Miele site for £999. It’s a bit taller than the first two fridge options, standing at 201.1cm. (Its depth and width are the same.) This means it has a slightly larger capacity, 328 litres, which comes to 20 shopping bags of food. It is A++ rated, with frost-free technology. The door shelves can be easily removed for cleaning and are dishwasher safe, which is a nice touch.  

Series 120

Finally, there’s the Miele KFN29162D, which has the same dimensions and internal capacity as the previous model. (It's pictured above.) It’s also A++ rated but has a slightly different interior, including a stainless-steel bottle rack.

You can buy it from Appliances Direct for £878.98, which is a really great offer, considering that its RRP is £999 (which is the price it's going for on the Miele site). It's also included in the cashback deal.

All of the fridge freezers included in the deal are listed on Miele's site, so you can compare specs.

If you’re browsing for offers, LG has a similar deal, with up to £300 cashback per appliance. The LG deal is available until 14 July.
