Well that's put the cat in amongst the pigeons!
I just got a quote for Lucy from Halifax pet insurance £160.92 (£13.40 month) for
£6000 per year (total for all conditions in each year)
£60 XS payable for each condition each year and it provides
£200 Behavioural Problems coverso a ten year claim on the xtra plan, assuming the premium remained static, which in reality it wouldn't, would cost (£13.40x12x10)+(£0x10) = £2208.00 in premiums and excess payments.
Healthypets gold cover gives me £5000 per condition for life with £50 excess (one off payment per condition) £100 excess for 3rd party claims - £6.15 monthly. over ten years the premiums would be (£6.15x12x10)+£50 = £788 that leaves a difference of only £1420 to add to the £5000 per condition before i would have paid out more than i would have under Halifax and this is further reduced to £420 when you take into account that Halifax is £6000 not £5000 cover.
I think i will have to consider them seriously when i renew Lucy's policy in April
Policy details
HereETA they do cover 'dental treatment due to illness' as well as 'due to accident'
