Energy tariffs with free boiler cover: UK comparison guide
Some UK energy deals include boiler cover (or a discounted policy) as a perk. This guide explains what “free boiler cover” usually means, what to check, and how to compare tariffs fairly—without overpaying for the energy part.
- See what’s typically included (repairs, annual service, controls, parts & labour)
- Check eligibility: boiler age/type, pre-existing faults, landlord/tenant rules
- Compare total cost: unit rates, standing charges, exit fees, and cover excess
Boiler cover is subject to eligibility and insurer/provider terms. We show how to compare fairly; we don’t guarantee savings or cover acceptance.
Fast answer: are “free boiler cover” energy tariffs worth it?
They can be—especially if you already pay for boiler cover and the included policy genuinely matches what you need. But many “free boiler cover” offers are best treated as a bundle: you must compare the total cost (energy + cover) against a normal tariff plus buying cover separately.
What it usually means
Boiler cover included for a limited time (e.g., 6–12 months) or discounted, sometimes provided by a partner insurer, not the energy supplier.
Best quick check
Ask: What’s the energy price? (unit rates + standing charges) and what’s the cover value? (excess, limits, exclusions, service included?).
Common gotcha
Coverage can be declined due to boiler age, condition, or pre-existing faults. “Free” cover may still have a call-out excess.

How to compare energy deals that include boiler cover (step-by-step)
To compare fairly, you need to separate the energy tariff from the boiler cover policy. Providers may bundle these in different ways—so focus on what you’ll actually pay and what protection you’ll really get.
- Confirm your meter setup: single-rate, Economy 7, smart, or prepayment. Some bundle tariffs are only available for certain meter types or payment methods (e.g., monthly Direct Debit).
- Compare energy costs first: unit rates (p/kWh), standing charges (p/day), tariff length, and any exit fees. These vary by region and can outweigh the value of cover.
- Read the boiler cover summary: check annual benefit limit, excess, what counts as an emergency, and whether an annual service is included or costs extra.
- Check eligibility and pre-existing conditions: cover often excludes pre-existing faults, poor maintenance, or boilers above a certain age. Some policies require the boiler to be in “good working order” at start.
- Check who provides the cover: it may be a third-party insurer/assistance company, with different terms to the supplier’s energy contract. Make sure you know who to call and typical response times.
- Price the “after free period” cost: if cover is free for 6–12 months, confirm what happens next—auto-renewal, monthly price, and how to cancel.
What to compare on the energy side
- Unit rate
- The p/kWh you pay for gas and electricity.
- Standing charge
- Daily fixed charge; can be high even if you use little energy.
- Tariff type
- Fixed, variable, tracker; each has different price risk.
- Fees & terms
- Exit fees, payment method restrictions, and contract length.
What to compare on the boiler-cover side
- Excess (call-out fee)
- What you pay per claim/visit. “Free” cover can still have an excess.
- Annual claim limit
- Maximum the policy pays in a year (or per claim).
- What’s included
- Boiler only vs boiler + controls vs full heating system/plumbing.
- Exclusions
- Pre-existing faults, sludge/scale, cosmetic damage, and non-standard parts.
Comparison table: bundled tariff vs separate boiler cover
Use this table as a quick decision aid. The “best” option depends on your boiler’s condition, your appetite for unexpected repair bills, and whether a bundle forces you onto a pricier tariff.
| Option | Best for | Watch-outs | What to check |
|---|---|---|---|
| Energy tariff with “free” boiler cover | You already buy cover and want one joined-up monthly cost (and the tariff is still competitive). | Cover may be time-limited; eligibility checks; excess may apply; “boiler only” can be narrow. | Cover duration, cancellation, excess, annual limit, exclusions, and supplier tariff exit fees. |
| Cheapest suitable energy tariff + separate boiler cover | You want maximum flexibility to switch energy without impacting a separate cover policy. | Two separate renewals; you must ensure the cover policy is reputable and matches needs. | Total annual cost of cover (including service), excess, response times, and claims limits. |
| Energy tariff only (no cover) | Newer boiler, savings buffer, or you prefer to pay as issues arise (self-insure). | Unexpected repair costs; winter breakdown stress; may need emergency engineer at short notice. | Typical repair costs in your area, boiler age/condition, and whether you can cover an excess repair bill. |
Decision checklist (quick)
- Is the tariff competitive in your region (unit rates + standing charge), even without the cover?
- Is the cover actually “boiler cover” (or just home emergency add-on / partial protection)?
- What is the excess, and could you afford it if you needed a call-out?
- Any boiler age limit or requirement for a recent service?
- What happens after the free period (auto-renewal, price, cancellation route)?
- Do you need landlord permission (tenant) or is the landlord already responsible?
Who it suits / who it doesn’t
Often suits:
- Homeowners with an older boiler
- Households that value predictable costs
- People who already pay monthly for cover
Often doesn’t suit:
- Tenants where landlord handles repairs
- Very low energy users (standing charges matter)
- Anyone wanting freedom to switch frequently
Two realistic scenarios (with estimated numbers)
These examples show how to think about the trade-offs. Figures are illustrative and will vary by region, tariff availability, and cover terms.
Scenario A: homeowner already buying cover
- Current boiler cover: £18/month (£216/year), £60 excess
- Tariff option 1 (no perk): estimated energy £1,520/year
- Tariff option 2 (bundle): energy is £1,610/year and includes 12 months cover
- Estimated comparison: option 1 total ˜ £1,520 + £216 = £1,736/year vs option 2 total ˜ £1,610/year (cover included for the year)
- What could change it: if cover is only 6 months, or if excess/limits make it poorer value than your current policy.
Scenario B: low energy use, perk can be a trap
- Small flat, low usage: energy on best tariff estimated £980/year
- Bundle tariff: energy estimated £1,090/year, includes “free boiler cover” for 12 months
- Separate boiler cover quote (basic boiler-only): £12/month (£144/year), £75 excess
- Estimated comparison: best energy + cover ˜ £980 + £144 = £1,124/year vs bundle ˜ £1,090/year
- But: if your landlord is responsible, your effective value of cover may be £0—making the bundle likely worse than just choosing the cheapest suitable energy tariff.
Assumptions: Direct Debit payment, single-rate meter unless stated, cover cost based on typical market pricing. Energy totals are estimated illustrations, not quotes.
Costs, exclusions and common pitfalls (UK)
Boiler cover policies vary widely. Even when an energy tariff advertises “free boiler cover”, the real-world value depends on the fine print.
1) Excess and limits
Many policies include an excess per claim/visit (e.g., £50–£100). Some have annual caps (for example, a maximum payout per year).
2) Pre-existing faults
Breakdowns linked to pre-existing issues are commonly excluded. If your boiler is already temperamental, cover may not help immediately.
3) What’s classed as “boiler”
Some offers are boiler-only. Others include controls, radiators, pipework, and plumbing/drainage. Ensure it matches your risk.
Other UK-specific checks
- Boiler age/type: older or non-standard boilers may have restrictions.
- Annual service: sometimes not included, or only included once per year under conditions.
- Response times: “emergency” attendance targets vary and may exclude peak periods.
- Parts availability: if parts are obsolete, the policy may offer limited alternatives.
- Home access: you may need to provide access promptly, or claims can be affected.
Common pitfalls we see
- Higher standing charges quietly offset the value of the “free” cover.
- Cover auto-renews after the free period at a higher monthly price.
- Wrong meter/payment method: advertised tariffs may be Direct Debit only.
- Tenancy mismatch: tenant pays for cover but landlord controls boiler repairs.
- Bundle lock-in: switching energy early triggers exit fees or changes perk eligibility.
FAQs: energy tariffs with boiler cover (UK)
Is boiler cover really free with some energy tariffs?
Sometimes it’s free for a limited time, or included as a perk where the cost is effectively built into the tariff pricing. Always compare the energy unit rates and standing charges to see if you’re paying more overall.
Will I be accepted for boiler cover if my boiler is old?
Not guaranteed. Many policies have eligibility rules based on boiler age, type, condition, and service history. Pre-existing faults and poor maintenance are commonly excluded.
Does boiler cover include an annual boiler service?
Sometimes, but not always. Some deals include one service per year; others only cover breakdowns. Check whether a service is included, any scheduling limits, and whether parts are covered during servicing.
If I switch energy supplier, what happens to the boiler cover?
It depends on the product structure. If cover is a separate insurance/assistance policy, it may continue until you cancel it. If it’s a tariff perk, you may lose it when you leave. Always check terms and cancellation instructions for both agreements.
Can tenants get boiler cover through their energy tariff?
You may be able to buy cover, but it may not be useful if your landlord is responsible for boiler repairs. Many tenancy agreements make the landlord responsible for heating and hot water. Check your tenancy terms before paying for cover.
Are these deals available for prepayment meters?
Often fewer tariffs are available for prepayment, and bundle perks may be restricted. If you have a prepay meter (or want to switch to Direct Debit), compare what’s available for your meter and ask whether you’d need a meter change.
Do I still pay anything when I claim?
Possibly. Many policies have an excess per call-out or claim, and may exclude certain parts or types of faults. Ask for the excess amount and examples of exclusions before choosing a bundle.
What’s the difference between boiler cover and home emergency cover?
Boiler cover focuses on boiler breakdowns and sometimes controls/heating. Home emergency cover can include plumbing, electrics, drainage and locks, but may have lower limits and may not cover full repairs—often just making safe/temporary fixes. Always check the policy scope.

How we assess “free boiler cover” tariff claims
We focus on user outcomes: total expected cost and realistic cover value. Our editorial approach is to treat the bundle as two products:
- Energy contract: unit rates, standing charges, contract length, payment method restrictions, exit fees, and regional pricing differences.
- Cover policy: eligibility, excess, claim limits, included components (boiler only vs heating system), exclusions, and what happens after the introductory period.
Where we use example figures, we label them as illustrative and state assumptions. We avoid implying guaranteed acceptance, response times or savings.
