There are three distinct protection products that are relevant to most mortgage borrowers. Life assurance pays a lump sum if you die during the policy term. Critical illness cover pays a lump sum on diagnosis of a qualifying serious condition. Income protection pays a monthly benefit if you cannot work due to illness or injury. These are different products that serve different purposes — not variations of the same thing.
Decreasing term assurance is the most common product sold alongside mortgages. The sum assured reduces over the policy term, roughly mirroring the outstanding balance on a repayment mortgage. It is cheaper than level term and appropriate if your sole objective is ensuring the mortgage is repaid if you die.
Critical illness policies pay out on diagnosis of conditions from a defined list — but not every serious illness is covered, and not every diagnosis of a covered condition qualifies. Most policies cover cancer, heart attack, stroke, multiple sclerosis, and a range of other conditions — typically 50 to 100 in total depending on the insurer.
Income protection is arguably the most important protection product for working-age borrowers, yet it is the least commonly held. It pays a proportion of your pre-disability income — typically 50–70% — for as long as you cannot work, until you return to work, reach retirement age, or the policy term ends.
Mortgage payment protection insurance (MPPI), sometimes called accident, sickness, and unemployment cover, is frequently sold at the point of mortgage. It covers your monthly mortgage payment for a limited period — usually 12 to 24 months — if you lose your job or fall ill.
