Level term insurance pays a fixed lump sum if you die at any point during the policy term. Choose £250,000 over 25 years and it is £250,000 in year one and £250,000 in year twenty-four. The premium is fixed at outset too, so what you agree on day one is what you pay throughout.

That predictability is the whole point. It makes the cover easy to plan around and easy to budget for, and it is why level term is the default recommendation for most families protecting an income rather than a specific shrinking debt.

The honest test is whether the thing you are covering gets smaller. A repayment mortgage does, which is what decreasing cover is designed for and why it costs less. Income replacement, childcare and an interest-only balance do not.

Plenty of households need both, and it is entirely normal to run a decreasing policy against the mortgage alongside a level policy for everything else. Buying one policy to do both jobs usually means over-paying on one half and under-covering the other.

The sum assured is fixed in cash terms, which means inflation erodes it. £250,000 in 2026 will not buy in 2046 what it buys now, and over a 25-year term that gap is substantial. If protecting real spending power matters more than a predictable premium, increasing cover is the honest alternative, at a higher and rising cost.

Level term also has no cash value. If you outlive the term, the cover simply ends with nothing paid back. That is not a flaw, it is the trade that makes the premium low, but it is worth being clear-eyed about at the outset.
