If you take out a boiler cover policy and then find your insurer goes bust, your policy will become invalid. You’ll then need to find another company to cover your boiler.
If you’re in the middle of making a claim when your insurer goes out of business, the Financial Services Compensation Scheme (FSCS) may be able to step in and pay your claim. You’ll need to get in touch with the FSCS to see if you’re eligible.
