My colleague has just asked me a generic question about plumbing
costs.. Quite why he thinks I will know I have no idea, but I am sure
that someone here would be able to help.

It turns out that his Mums loft header tanks is 'split'.. Water is
pouring out and she has called someone in to take a look.

The first nightmare is that apparantly, this is NOT covered by her
house insurance? Does that sound right?

But more imporantly, the costs.. She has been quoted £450, which seems
an awful lot....

To be honest, I can't tell you much about this, as its word of mouth.
And its not like we can go and visit to take a look as she lives at
the other side of the country...

Does anyone have an approximate idea of what she should be looking to
pay for a job like this?
