Just renewed by home /contents insurance - went from the PO to Nationwide. Couple of things seem to have changed recently:
Premiums have gone right down. I paid £390 last year - this year, using a compare market site, £108. Not especially grand 4 bed terrace. Pretty sure I would have checked at the last renewal date, so I don't know what's going on there.
Cover has gone up. They weren't interested in anything under £2000, or building costs below £1m.
When I phoned to cancel, they did the usual 'we'll try and beat that quote', but I'm tired of that now. I'm taking all of these renewals as final and best, even it does cost me a few quid.
