Costly Home Emergencies

What’s the most expensive unplanned ‘home emergency’ you’ve ever had to deal with?

Making and sticking to a budget is all well and good, but sometimes the universe (or forgetful neighbour) has other plans for our hard-earned savings.

Have you had to dip seriously into savings (or even borrow?) to deal with such an event - maybe it was a boiler fail on New Year (like me), or leaking flashing on a chimney (me again) or an overflowing fish tank filter (yep, me again)?
