Advice on best after market warranty for a Defender 2 HSE 2020

Hello All,
My Defenders warranty has lapsed. LR want me to pay £330 for a pre warranty inspection before they extend the warranty.
As the warranty itself costs over £900 I am loath to spend the additional £330. Can anyone recommend, from experience, a very good 3rd party warranty supplier?

Thanks in advance
