Is Boiler Cover Worth It? An Honest 2026 Guide

The simple version of the maths

Boiler cover trades a small, predictable monthly cost for protection against a large, unpredictable one. Whether it pays off comes down to three numbers: what you pay in, what you'd pay out if you didn't have it, and how likely a breakdown actually is.

As a rough guide for 2026 (figures are indicative and vary by provider, boiler age and where you live):

What you might pay	Typical range (2026)
Basic breakdown-only cover	£6–£15 / month
Mid-tier cover (breakdown + annual service)	£15–£30 / month
Full cover (boiler, controls, central heating)	£25–£50 / month
Typical excess per claim	£0–£99
One-off repair without cover	£150–£600+
New boiler (combi, supplied & fitted)	£1,800–£3,500+

Run a quick comparison. If you pay £18 a month, that's £216 a year. A single mid-sized repair — a faulty diverter valve, a pump, a PCB — can easily match or beat that. But in a year where nothing breaks, you've paid £216 for peace of mind and (on the right plan) an annual service. The honest answer is that over a single year, paying as you go is often cheaper; over several years, cover smooths out the shock of one big bill.

When boiler cover is usually worth it

• Your boiler is older (roughly 7+ years). Breakdowns and part failures become more likely as boilers age, so the odds of claiming go up. This is where cover most often pays for itself.
• You don't have a savings buffer. If a surprise £400 repair would genuinely hurt, paying a fixed monthly amount is easier to manage than an unplanned bill in January when the heating dies.
• You value the certainty. A capped, known cost and a number to call beats hunting for an available engineer mid-cold-snap. For many people, that convenience alone is the point.
• You're a landlord. You're legally responsible for an annual Gas Safety check, and a tenant without heating is an urgent problem. Cover that bundles the gas safety certificate and prioritised repairs is often a sensible operating cost — see our landlord boiler cover guide.
• You'd want the annual service anyway. A standalone service costs roughly £80–£120. If a mid-tier policy includes one, the effective cost of the breakdown cover shrinks considerably.

When paying as you go can win

• Your boiler is new or under manufacturer's warranty. Many boilers come with 5–12 years' guarantee. While that warranty runs (and you keep up the annual service it requires), paying separately for breakdown cover often duplicates protection you already have.
• You have an emergency fund. If you can comfortably absorb a £500–£600 repair, self-insuring — setting aside the monthly amount you'd have spent — can leave you better off over time, and the money stays yours.
• You're disciplined about servicing. A well-maintained modern boiler that's serviced annually is statistically far less likely to fail. Booking your own Gas Safe registered engineer once a year may cost less than a full-cover policy.
• The excess eats the benefit. A cheap-looking plan with a £99 excess on every claim can mean you're paying the monthly premium and most of a small repair anyway.

What to check before you buy

If you decide cover is worth it, the headline price is the least important number. Check these instead:

• The excess. A £0-excess plan at a slightly higher monthly price often beats a "cheap" plan with a £60–£99 excess per call-out.
• Claim limits. Some policies cap the number of call-outs per year or the total repair spend. A low annual limit can leave you exposed exactly when you need the cover most.
• Exclusions and boiler age. Pre-existing faults, sludge/scale damage, boilers over a certain age, and "beyond economical repair" replacements are commonly excluded. Read this section before anything else.
• Insurance vs. service plan. A true boiler cover insurance product is regulated by the FCA and you'll get a policy document; a "service plan" or maintenance contract is not insurance and the protections differ. Know which one you're signing up to.
• What's actually covered. Boiler only? Boiler and controls? Full central heating including radiators and pipework? The cheapest tier may not include the parts most likely to fail.
• Waiting periods. Many policies won't pay out on a claim in the first 14–30 days, so you can't sign up mid-breakdown and claim immediately.

A balanced verdict

There's no universal answer — anyone telling you boiler cover is always essential, or always a rip-off, is overselling their case. The honest position is this: cover is most worthwhile when your boiler is older, your savings are thin, or you're a landlord; it's least worthwhile when your boiler is new, still under warranty, and you have a buffer to fall back on. Either way, an annual service by a qualified engineer is the single best thing you can do to avoid breakdowns in the first place.

If you've decided cover makes sense, the difference between a good plan and a poor one is usually the excess, the limits and the exclusions — not a few pounds a month.
