Your boiler warranty has just expired. Now every energy company wants to sell you boiler insurance. But is that actually what you need?
Boiler service plans and boiler insurance are two different products. Choosing the wrong one could mean overpaying by hundreds of pounds. Picking the right one protects your home and your wallet.
This guide breaks down exactly how each option works. You will learn what they cost, what they cover and what they quietly exclude. By the end, you will know which option fits your boiler, your budget and your situation.
Here is the short version. A boiler service plan covers your annual service and preventative maintenance. Boiler insurance covers breakdown repairs, parts and labour. Most homeowners with a boiler still under warranty only need a service plan. If your boiler is older and out of warranty, insurance may be worth considering. But watch for excess fees and exclusions that inflate the real cost.
What Is a Boiler Service Plan?
A boiler service plan is a monthly payment that covers your annual boiler service. It spreads the cost of routine maintenance into small, predictable instalments rather than a single lump sum.
Plans typically cost between £5 and £17 per month. For that, a Gas Safe registered engineer visits once a year to inspect, test and clean your boiler. The service checks for faults, ensures safe operation and keeps everything running efficiently.
A service plan is preventative, not reactive. Its job is to catch small problems before they turn into expensive breakdowns.
Regular servicing also keeps your manufacturer’s warranty valid. Most boiler manufacturers require proof of an annual service. Skip it and your warranty could be voided, leaving you exposed to full repair costs.
What Does a Boiler Service Plan Typically Include?
- Annual boiler service by a Gas Safe registered engineer
- Safety and efficiency checks
- A service reminder so you never miss your annual appointment
- Written service report for your records
- Warranty compliance documentation
Some providers, including Domestic Group, offer plans that go beyond basic servicing. These comprehensive plans bundle breakdown cover, parts, labour and 24/7 emergency call-outs alongside the annual service.
What Is Boiler Insurance?
Boiler insurance is a policy that pays for repairs if your boiler breaks down. It is sometimes called boiler cover or boiler breakdown cover. Unlike a service plan, its primary purpose is reactive. It responds after something goes wrong.
Policies typically cost between £10 and £25 per month. The price depends on the level of cover, your boiler’s age and where you live. Basic policies cover only the boiler itself. More comprehensive policies extend to your full central heating system, including radiators, pipework and controls.
Many boiler insurance policies include an annual service as part of the package. However, not all do. Always check before you buy.
Key Features of Boiler Insurance
Breakdown call-outs, parts replacement and engineer labour are usually included. Most policies provide a 24/7 helpline for emergencies. Some also offer extras like plumbing, drainage and electrical cover for a higher premium.
There are important limitations to understand. Boiler insurance is regulated by the Financial Conduct Authority (FCA), which means you have recourse through the Financial Ombudsman if something goes wrong with a claim. Service agreements, by contrast, are not FCA-regulated.
Common Boiler Insurance Exclusions
Before signing up, check for these common exclusions:
- Pre-existing faults are almost never covered
- Sludge and limescale damage is excluded by many providers
- Boilers over 10 to 15 years old may not be eligible
- Waiting periods of 14 to 30 days apply before you can make a first claim
- Cosmetic damage to the boiler casing is typically excluded
These exclusions catch many homeowners off guard. Reading the full policy terms before purchasing is essential.
Boiler Service Plan vs Insurance: The Key Differences
The simplest way to understand the difference is side by side. This table compares the two options across the factors that matter most.
| Feature | Boiler Service Plan | Boiler Insurance |
|---|---|---|
| What it covers | Annual service and maintenance | Breakdown repairs, parts and labour |
| Typical monthly cost | £5 to £17 | £10 to £25 |
| Annual service included | Always | Sometimes (check the policy) |
| Breakdown repairs | Not usually (unless a comprehensive plan) | Yes |
| Parts and labour | Not usually included | Usually included |
| Call-out / excess fees | Often none | Typically £60 to £100 per call-out |
| Regulatory protection | Not FCA-regulated | FCA-regulated |
| Waiting period | None | Usually 14 to 30 days |
| Best suited for | Boilers under warranty or under 5 years old | Older boilers without warranty cover |
The excess fee is where many homeowners get caught out. A policy advertising £15 per month sounds affordable. But if each call-out carries a £60 excess, your actual cost per repair jumps significantly.
Some providers offer plans that combine both servicing and breakdown cover without the excess fees. Domestic Group’s service cover plans start from £17 per month and include an annual service, breakdown repairs, parts and labour with no call-out fees and no excess charges.
That combination of servicing and breakdown cover, without hidden costs, is worth looking for regardless of which provider you choose.
The Real Cost: A 5-Year Comparison
Monthly premiums only tell part of the story. To understand the true cost, you need to look at total spend over several years.
Scenario A: Service Plan Only
A service plan at £10 per month costs £600 over five years. That covers five annual services, which would cost £350 to £600 if booked individually. Any repairs during that period are paid for separately, with average boiler repair costs in the UK sitting between £150 and £500.
Total 5-year cost: £600 plus any repairs needed.
Scenario B: Boiler Insurance
Boiler insurance at £20 per month costs £1,200 over five years. Most policies include an annual service. Each breakdown call-out typically incurs a £60 excess.
If you make three claims over five years, add £180 in excess charges. That brings your total to around £1,380. Many providers also increase premiums significantly at renewal after a discounted first year. A 30% renewal hike is not uncommon.
Total 5-year cost: approximately £1,380 to £1,500+.
Scenario C: Self-Insuring
Putting £15 per month into a savings account gives you £900 after five years. That is enough to cover one to two average repairs or contribute toward a boiler replacement. You would still need to book and pay for annual services separately (£70 to £120 each).
Total 5-year cost: £900 in savings, minus any services or repairs paid from the pot.
According to Which?, most homeowners are financially better off paying for repairs as and when they are needed, rather than maintaining a boiler insurance policy. Cover can still make sense for stress reduction and cost predictability, but the numbers often favour a service plan combined with either self-insuring or a comprehensive no-excess cover plan.
Which Option Is Right for You?
The right choice depends on your boiler’s age, your financial buffer and how much uncertainty you are comfortable with.
Your Boiler Is Under Warranty (0 to 5 Years Old)
A service plan is all you need at this stage. Your manufacturer’s warranty already covers breakdowns and parts. The only requirement is keeping up with your annual boiler service to maintain the warranty.
Paying for boiler insurance on top of a valid warranty means doubling up on cover you already have.
Your Boiler Is 5 to 10 Years Old and Out of Warranty
This is where the decision matters most. If you have savings to cover an unexpected £300 to £500 repair bill, a service plan combined with self-insuring may be the smartest approach.
If a surprise repair bill would cause financial stress, a comprehensive service plan with built-in breakdown cover offers peace of mind. Look for one with no excess fees and no call-out charges, so the monthly price is genuinely all you pay.
Your Boiler Is Over 10 Years Old
Insurance becomes harder and more expensive to obtain for older boilers. Many providers set maximum age limits at 10 to 15 years. Even those that accept older boilers often exclude the most expensive components.
At this stage, your money may be better directed toward a new boiler fund. A service plan keeps the existing boiler running safely for as long as possible while you plan your next step.
You Want Zero Hassle
A comprehensive plan from a single local provider removes all the guesswork. One monthly payment. One phone number. One team of engineers who know your system. No excess fees, no exclusions to decode, no renewal-day price shocks.
What to Look for in a Boiler Service Plan
Not all service plans are equal. Before committing, check for these essentials:
- Gas Safe registered engineers performing all work (this is a legal requirement, verify on gassaferegister.co.uk)
- No hidden call-out or excess fees so the monthly price is genuinely what you pay
- Annual service included as standard, not as an optional extra
- Clear terms explaining exactly what is and is not covered
- Local engineers with fast response times, especially during winter
- Stable, transparent pricing with no introductory offers that double at renewal
- Option to upgrade to include breakdown cover if your needs change
Local providers often outperform national companies on response time and price. National providers like British Gas charge upwards of £99 for a single boiler service. A local team can typically offer the same service, or better, within a comprehensive plan for a lower monthly cost.
We service hundreds of boilers across Hertfordshire every year with our own Gas Safe registered engineers. Our plans start from £17 per month with no excess and no call-out fees. That consistency is something national call centres simply cannot match.
Frequently Asked Questions
Is a Boiler Service Plan the Same as Boiler Insurance?
No. A boiler service plan covers your annual boiler service and preventative maintenance. Boiler insurance covers breakdown repairs, parts and labour. Some comprehensive plans combine both, but they are fundamentally different products with different costs and different levels of protection.
Do I Need Boiler Insurance if My Boiler Is Under Warranty?
Usually not. If your boiler has a valid manufacturer’s warranty, breakdowns and faulty parts are already covered by the manufacturer. You only need an annual service to keep that warranty active. A service plan is the most affordable way to ensure that happens.
How Much Does Boiler Cover Cost Per Month in the UK?
Basic boiler-only insurance typically costs £8 to £15 per month. Comprehensive policies covering central heating range from £15 to £25 per month. Many policies also charge a £60 to £100 excess per call-out on top of the monthly premium. Service plans are generally cheaper, starting from around £5 to £17 per month.
Does Home Insurance Cover Boiler Breakdown?
Standard home insurance does not usually cover boiler breakdowns. Some insurers offer home emergency cover as a paid add-on. However, this is typically limited in scope and may not include an annual boiler service. Check your existing policy before purchasing separate cover to avoid paying twice.
What Is Not Covered by Boiler Insurance?
Common exclusions include pre-existing faults, damage from sludge or limescale build-up, boilers older than 10 to 15 years and claims made during an initial waiting period of 14 to 30 days. Some policies also exclude specific components or set annual claim limits. Always read the full terms before purchasing.
The Bottom Line
A boiler service plan and boiler insurance solve different problems. The service plan protects your boiler’s health through regular maintenance. Insurance protects your wallet if something breaks. For most homeowners, a service plan is the essential foundation, and it costs significantly less.
If you want breakdown cover too, look for a plan that bundles it with your annual service. Prioritise plans with no excess charges, no call-out fees and transparent pricing that will not spike at renewal.
Domestic Group’s boiler service plans start from £17 per month. Every plan includes an annual service carried out by local Gas Safe registered engineers. There are no call-out fees and no excess charges. Explore our service cover plans and choose the right level of protection for your home.
