Cover My Pet offer Lifetime, Time Limited and Maximum Benefit Insurance policies. There are three levels of Lifetime cover policy to choose from. Their policies cover theft and straying, vet fees, third party liability, complementary treatments, death from accident or illness and holiday cancellations with different pay out limits dependent on the cover you buy. There are also lower limits for CT and MRI diagnostics and cruciate ligament treatment pay out.  Full details can be found on the CoverMy Pet website.
 
Lifetime Insurance is the most comprehensive level of pet insurance available from CoverMy Pet. It will provide cover for accidents and illnesses including ongoing conditions for the duration of the pet's life as long as the policy is renewed and there is no break in cover. You can choose between three levels of vet fee cover; £2,000, £5,000 and £10,000 per year. The annual vet fee limit is refreshed when you renew the policy. 

Their Time Limited policy has a time limit on the cover available for any particular condition, accident or illness. Each condition is covered for a maximum of 365 days from the date of the first claim for that particular condition or until the cover limit of £3,000 is reached. Cover for a particular condition could extend over two policy years until 365 days from the first claim for the condition is reached or the cover of £3,000 is exhausted. 

CoverMyPet Maximum Benefit Insurance provides a financial limit on the cover for a particular illness, condition or accident, but not a time limit, while the policy is active. So claims for the same condition can continue until the limit of your policy is reached. They offer £4,000 of cover per condition, no matter how long your claims go on for, until the limit is reached.
