Sorry for late reply, been having computer troubles & only just seen your post.
My battle still goes on with my Freeholder & (non) Managing agent over the buildings insurance! You may have had your return call from Lease now but basically they told me I was entitled to challenge the amount I was being asked to pay if I believed it was wrong and that by law I was entitled to a copy of the policy document detailing the amount insured, premium etc.
Yes my buildings insurance is a block policy covering 37 properties, we too are all paying different amounts with no rhym or reason and are also insured through AXA (there aren't many companies that do block policies for leasehold properties.) Unfortunately you will find AXA won't be too forth coming unless you are lucky enough to get through to someone helpful & sympathetic but even then they can't tell you much because you aren't actually the policy holder; your agent or freeholder are & because they don't have anything to do with the split of the policy.
I threatened my agent & freeholder with action if I did not receive a reasonable explanation over the differing amounts being paid & if I did not receive a copy of the policy document. My lease states I have to pay to the agent an amount equal to the amount expended for buildings insurance and on last years receipt for my payment it stated that no property has a single sum attributable to it so when I finally received a copy of the policy summary I had all the details I needed to calculate my proportion of the premium. Basically the total premium (£7,000 ish) divided by the number of properties covered (37). I worked out my proportion should be £205 not £275 and I have been overcharged £50 in 2006 & again in 2007.
Lease advised on the payment that I could either pay the full amount & then try to get back what I thought I was owed; but agreed its harder to get back money you have already paid or I could pay the amount I had calculated & wait & see if they take action to try & get any more or I could withhold payment altogether & refer my case to LVT for a decision.
I decided not to pay anything incase making a payment is seen as an admission that the full amount is owed & because I want back the money I was overcharged aswell I could see it getting complicated.
I got a letter back at the beginning of November last year from the agent saying they would get back to me & until Monday last week I'd heard nothing! Then I received a demand for £528 from a
debt collection
agency threatening me with all kinds of action if I didn't pay up!
I phoned the debt collection agency & told them I had queried the amount with the freeholder & agent & the ball had been left in their court. At first they gave me a lecture about not paying & how I should have paid & claimed the difference back because I'm not currently insured (which can't be correct if its a block policy) but when I told them I had taken advice & had threatened to take my case to LVT they just asked me to send them copies of the letters sent & recieved & will contact me once they've received & gone through it all.
I've still got to get it all posted & am debating whether to send a payment of £205 minus the £100 I've been overcharged but I'm not willing to pay anymore than this & there is no way in hell I am paying any kind of late payment penalties,
interest
or fee's to the debt collection agency because my agent & freeholder can't be bothered to answer their leaseholders!
I don't know if this helps you at all in your case but IMO no one should pay more than they think they should just because they receive a demand unless its from a court!
