The monthly price is usually the first thing you see when comparing boiler cover. It is rarely enough to make the decision. A low-priced plan can mean a larger excess, narrower cover or a service that must be arranged separately. A more expensive plan may include things you already have elsewhere.
Start with the paperwork for your own boiler and home. Then compare what would happen in a quiet year, in a year with a covered repair, and if the boiler cannot be repaired. This is a practical comparison guide for UK homeowners, not a provider ranking or a recommendation to buy a particular policy. The examples below are invented arithmetic, not current offers.
Know which product you are comparing
Boiler cover, central heating cover and home emergency cover are not interchangeable descriptions. The name alone does not establish whether radiators, controls, pipework or an annual service are included. Ask for the actual policy or service agreement and its summary, then compare the listed components and events.
| Description you may see | Question to ask |
|---|---|
| Boiler cover | Which parts of the boiler, flue and controls are included? |
| Central heating cover | Are radiators, valves, pumps and accessible pipework included? |
| Annual service | Is it included, how is it booked and when will it happen? |
| Home emergency cover | Which emergencies qualify, and what repair or financial limits apply? |
| Replacement benefit | What conditions apply, and is it a replacement, contribution or discount? |
| Service agreement or insurance | What type of contract is this, and what complaints process applies? |
Read documents for the exact product you are offered. A company can sell several plans with different terms. A comparison written for one version can be wrong for another. Save the dated documents with your quote rather than assuming you will be able to find the same version on the website later.
Check existing protection before buying more
A manufacturer warranty, an installer arrangement and a home insurance add-on may each cover different things. Put them side by side. Note the expiry date, servicing conditions, contact route and relevant exclusions. Do not assume that two products covering similar events will both pay out, or that home emergency cover necessarily provides a full long-term repair.
If you have recently moved in, ask for the installation and service records that came with the property. If they are missing, say so when requesting cover. Guessing the age or maintenance history to get through a form can create a problem later. Get the provider’s answer about eligibility in writing where possible.
For a rented property, establish the landlord’s responsibilities and reporting process before buying a homeowner plan. This article does not set out landlord compliance duties. A tenant should not have to infer responsibility from a marketing page aimed at owner-occupiers.
Compare annual cost, then add the excess
Multiply the monthly payment by twelve and check whether there are additional fees or a different annual-payment price. Next, look at the excess: is it charged per claim, per visit, per repair or in another way? Those phrases can produce different bills when a fault needs more than one visit. Ask how a repeat fault is treated.
Here is a deliberately simple example. Assume both fictional plans provide equivalent cover, both include the service you need, and the excess is charged once per covered claim. Plan A costs £18 a month with a £95 excess. Plan B costs £25 a month with no excess. These assumptions are for the calculation only.
| Scenario | Plan A | Plan B |
|---|---|---|
| No claim in the year | £18 × 12 = £216 | £25 × 12 = £300 |
| One covered claim | £216 + £95 = £311 | £300 |
| Two separate covered claims | £216 + £190 = £406 | £300 |
A is £84 cheaper in the no-claim example. B is £11 cheaper with one covered claim under these assumptions. Neither calculation predicts whether your boiler will fail, whether the repair will be covered or how quickly it will be completed. The point is to see the trade-off rather than compare £18 with £25 in isolation.
For a second example, a fictional plan is £14 a month but does not include servicing. If your separate service quote is £110, the planned annual outlay is £168 + £110 = £278 before any excess or excluded work. Compare that with a service-inclusive plan only after checking that the service scope and other cover are genuinely comparable.
Read these exclusions before the sales headline
- Existing faults and waiting periods: when does cover begin, and what happens to a problem already present?
- Maintenance and system condition: what service records or remedial work are required?
- Sludge, scale and related damage: what is excluded, and who pays for investigation or cleaning?
- Access: can the engineer reach the boiler and components without removing fitted furniture or other finishes?
- Limits: are there caps per claim, per year or for particular components?
- Parts availability: what happens if the required part cannot be obtained?
- Non-standard equipment: is your boiler type, fuel, control system or installation eligible?
- Consequential work: does the plan repair surrounding decoration or only the covered component?
For an example of why the wording matters, this HomeServe policy document lists exclusions relating to known circumstances and exclusion periods. It is a specific policy version, not a summary of every HomeServe product or every provider. Read the documents issued with your own quote and ask for clarification where a term affects your situation.
A provider’s sales page is useful for identifying the broad package, but it should lead you to the conditions. For instance, Hometree’s boiler cover page links its replacement offer to terms and eligibility. This is an example of a question to investigate, not our endorsement of the offer. We have not ranked providers or tested their claims service.
Do not read “replacement” as “a new boiler in every case”
Ask how the provider decides that a boiler is beyond economic repair and what happens next. Is there an age condition? Is the benefit a full replacement or a contribution? Who pays installation-related costs, and what is excluded? Ask whether the benefit requires continuous cover or other conditions. A headline becomes useful only when you can describe the outcome for your own appliance.
Write the answer in ordinary language. For example: “If my boiler is not repaired, this plan offers X subject to Y; I would still pay Z.” Leave blanks where the provider has not answered. Those blanks are a reason to ask another question, not a reason to fill in the most reassuring interpretation.
Servicing still needs a place in the diary
The Energy Saving Trust boiler servicing guide explains annual servicing and using a Gas Safe registered engineer for a gas boiler. Check how the service is arranged, when it is due and whether the plan’s service meets any warranty conditions. A payment leaving your bank account does not confirm that an appointment has been made.
Keep the service record, engineer details and any recommendations. If remedial work is advised, ask for the reason, urgency and cost in writing. Do not remove the boiler casing or attempt gas repairs yourself. The aim of this guide is to compare arrangements, not to diagnose or repair an appliance.
Ask how help works in practice
Check the reporting route, hours of claims support, service area and how appointments are prioritised. “24-hour helpline” and “engineer arrives within 24 hours” are different promises. Ask which response commitments are contractual and which are targets. If someone in the household has particular needs, ask how the provider records and handles those needs.
Also check authorisation. If you call your own engineer first, will the provider reimburse anything? What evidence is required? Do not assume a policy will cover work commissioned outside its process. Save the claims number and policy reference where you can find them without searching a crowded inbox during a breakdown.
Keep renewal and cancellation on the same checklist
Record the renewal date, how the renewal price will be communicated, and the cancellation terms. Compare the renewal documents with the previous year rather than only checking the monthly amount. A changed excess or benefit can matter as much as a changed premium. If you switch, confirm dates and any new waiting period instead of assuming continuous practical protection.
For the wider household budget, keep cover payments separate from planned maintenance and a repair reserve. Our seasonal home maintenance guide helps organise the work that still needs attention, and the repair quote comparison checklist is useful when you pay for work directly. A material or job-pricing calculator cannot assess whether an insurance product suits your circumstances.
Frequently asked questions
Is boiler cover worth it?
There is no answer that fits every household. Compare existing protection, the actual terms, excesses, annual cost and what you could afford if an uncovered repair arose. Do not decide solely from the introductory monthly price.
Can I buy cover after the boiler breaks?
Do not assume a new plan will cover an existing fault. Check the existing-fault wording and start date. Providers may offer separate repair services, but those are a different purchase with their own terms.
Does cover include an annual service?
Only if the specific plan says so. Check booking arrangements and timing as well as inclusion. Keep the completed service record; the cover confirmation is not the service record.
Will an old boiler be replaced?
Eligibility for repairs and eligibility for replacement can differ. Read the age, economic-repair and replacement conditions for the exact plan. Ask what contribution or other costs could remain yours.
Is the excess payable on every engineer visit?
The charging basis depends on the contract. Ask about a repair requiring several visits and a fault that returns after it was apparently fixed. Keep the written answer with the policy.
Can I use my own engineer?
Check the provider’s approval process before commissioning work you expect it to pay for. Do not assume reimbursement simply because the engineer is qualified.
Should I cancel cover and save the money instead?
A savings pot and a cover contract handle uncertainty differently. A new savings pot may not meet an early large repair, while cover may exclude the event you face. Consider your circumstances and seek independent guidance if unsure; this guide does not recommend cancellation.
