M&S offered “home Emergency” cover as an add on for our home insurance for £4.20 a month. Covered anything in the house, plus up to £1k for the boiler (heat exchanger not included). Only caveat was that the boiler had to be serviced to mfrs recomendations schedule. The small print did read like they would try every trick in the book to avoid paying out… 😕 (My synical gut feeling).
Unfortunetley our boiler packed up last week, defying my efforts & the plumber. Had to call Glow-Worm out in the end. £288 fixed price, including a years cover.
Next year I’ll probably sign up for the M&S one.
Plumber reckoned to just insure the boiler, dont bother with rads/drains etc, as they rarely fail & dont cost a lot in comparison.
