I joined Tesco Pet Insurance last year with a premium of £446.56 per year, I had one claim and this July my premium was increased to £786.55 an increase of 76%. I phoned up to ask why and was basically told " that's what we deem a normal increase". I had moved house so told the assistant the new address which is 1.1 mile down the road with the same pre fix postcode, guess what my premium increased by a further £246.71 per year making a total of £1033.26 an overall increase of 132%. I complained and was given the usual corporate blurb. Strangely I did a pretend quote online with Tesco with the two postcodes and there was only £55.44 difference but no difference whatsoever with two other large providers!! Do not use Tesco they rob you blind especially if you move house!!!
