Energy tariffs with free boiler cover: compare UK (2026)
A tariff that bundles boiler cover can be great value — or a way to hide higher energy rates. Here is how to judge “free” cover in 2026 and compare the true total cost.

- How to compare bundled deals against energy-only tariffs
- Whole-of-market comparison by postcode — no obligation
Figures are illustrative estimates for the April–June 2026 Ofgem price cap period. Cover terms vary by provider — always read the policy.
Fast answer: is free boiler cover worth it?
“Free” boiler cover bundled with an energy tariff is only genuinely free if the energy rates are still competitive. If the unit rates or standing charges are higher than the cheapest energy-only tariff, you are effectively paying for the cover through your bill.
Key takeaway: compare the bundled tariff’s total estimated annual energy cost plus the value of the cover against a cheap energy-only tariff plus a standalone cover policy. Choose whichever combined total is lower for your home and boiler.
Compare energy deals — with and without cover
A postcode-based quote shows the energy tariffs available to you so you can judge whether a bundled boiler-cover deal really beats a cheaper energy-only option.
What we use to compare
- Postcode — region and standing charges.
- Annual usage — gas and electricity kWh, or an estimate.
- Payment method and meter type.
- Your priorities — lowest cost, or cost plus cover.
No pressure: a quote does not commit you to switching. Review rates, exit fees and any cover terms before deciding.

What “free” boiler cover usually includes — and excludes
Commonly included
- Annual boiler service
- Repairs to the boiler
- Sometimes central heating controls
- Engineer call-outs (often with limits)
Common exclusions
- Older boilers above an age limit
- Pre-existing faults
- Parts beyond a set age
- Excess fees per claim or annual repair caps
Always read the policy: two “free boiler cover” deals can differ hugely in what they actually pay for. Check the excess, repair limits, age limits and whether your boiler model qualifies.
How to compare bundled vs energy-only
Illustrative — typical dual-fuel home, estimated energy cost around £1,720/year on a competitive deal.
| Option | Energy cost | Cover | Combined total |
|---|---|---|---|
| Bundled tariff | ≈ £1,820 (rates ~£100 higher) | Included | ≈ £1,820 |
| Energy-only + standalone cover | ≈ £1,720 | ≈ £120/yr policy | ≈ £1,840 |
In this illustration the bundled deal is marginally cheaper — but flip the numbers (cheaper standalone cover, or higher bundled rates) and energy-only wins. The point is to compare the combined total, not the word “free”.
Pitfalls to avoid
Assuming “free” means no cost
The cover may be funded by higher energy rates. Always check the unit rate and standing charge.
Ignoring exclusions
Older boilers and pre-existing faults are often excluded — the cover may not help when you most need it.
Duplicating warranty cover
A newer boiler under manufacturer warranty may make bundled cover redundant — a cheaper energy-only tariff could be better.
Overlooking exit fees
Bundled tariffs are often fixed with exit fees. If you might move or the cap falls, factor those in.

FAQs
Are tariffs with free boiler cover actually free?
Only if the energy rates stay competitive. Higher unit rates or standing charges can mean you pay for the cover through your bill.
What does free boiler cover include?
Usually an annual service and boiler repairs, sometimes heating controls. Exclusions for older boilers, pre-existing faults and an excess are common.
How do I compare bundled vs standalone?
Add the tariff’s estimated energy cost plus cover value, and compare against the cheapest energy-only tariff plus a separate cover policy.
Is bundled cover worth it in 2026?
It can be if rates are competitive and the cover matches your needs. A newer boiler under warranty may make it redundant.
Does the price cap apply to these tariffs?
Fixed/specialist bundled products sit outside the cap; standard variable tariffs stay capped, with the next change from 1 July 2026.
