Boiler cover facts
In the UK, 23 million homes rely on gas boilers for central heating and hot water (80% of those households use combi gas boilers). While these systems are incredibly efficient, repairs can sometimes be costly, causing unexpected and substantial financial burdens – that’s why it’s crucial to consider a boiler cover plan to safeguard against any unexpected costs in the future.
A boiler cover is a plan that covers the cost of repairing or replacing your boiler if it breaks down. It can also cover the cost of an annual boiler service, as well as any call-out fees and labour costs. With a boiler cover plan in place, you can have peace of mind knowing that you’re protected against unexpected expenses.
The cost of boiler cover plans
The cost of boiler cover varies depending on the level of cover you need. Our Basic plan typically covers the cost of annual boiler service and unlimited breakdown callouts with repairs to your boiler and thermostat – this plan starts at £10.88 per month.
New boiler stats
Did you know boilers account for around 55% of your annual energy bills? That’s a huge chunk of your expenses! Choosing an efficient boiler can help you save money and reduce your carbon footprint.
Another interesting fact is that the average lifespan of a boiler is around 15 years. However, if you’re not properly maintaining your boiler, it may not last that long. Regular servicing and cleaning can help extend the life of your boiler and ensure it’s running at peak efficiency.
New boiler installation costs
Generally speaking, boiler installation costs can vary depending on several factors like; the type and size of boiler you have, the type of boiler you want to replace it with, the complexity of the installation, and the location of the property.
A standard boiler installation, which includes a new boiler and basic controls, can cost anywhere from £1,200 to £5,000 (including installation) but, the cost can increase if additional work is needed, such as upgrading the pipework. Here’s a pricepoint guide for boiler types and costs:
Boiler (without installation)
Installation (without boiler)
Total (boiler + installation)
£600 – £2,200
£500 – £1,000
£1,100 – £3,200
£650 – £2,700
£500 – £1,000
£1,150 – £3,700
£700 – £2,900
£500 – £1,000
£1,200 – £3,900
As you’ve seen, the type of boiler also plays a role in the cost. A combi boiler, which provides heating and hot water, is typically less expensive to install than a system boiler, which requires additional components such as a hot water cylinder. That’s one of the reasons combi boilers are used by 80% of UK households. Another noteworthy fact is gas central heating is used in 78% of UK homes.
The location of the property can also affect the cost of installation. Boiler installations in London and the Southeast of England tend to be more expensive than in other parts of the country.
It’s important to note that these are rough estimates, and prices can vary widely depending on the specific details of the job. It’s always best to get a quote to get a more accurate idea of the cost of boiler installation – just answer a few questions to see the ideal boiler for your home (and wallet!).

Upgrade your old inefficient boiler
Upgrading an inefficient boiler to an A-rated boiler can result in significant savings on energy bills for UK households. The average annual savings will depend on the type of property and the fuel source used. Here is a breakdown of the estimated annual savings for upgrading to an A-rated boiler in different types of UK properties:
- Detached house: The average annual savings for upgrading from an inefficient boiler to an A-rated boiler in a detached house is around £375.
- Semi-detached house: The average annual savings for upgrading to an A-rated boiler in a semi-detached house is around £305 for a gas boiler.
- Terraced house: The average annual savings for upgrading to an A-rated boiler in a terraced house is around £235 for a gas boiler.
- Flat or apartment: The average annual savings for upgrading to an A-rated boiler in a flat or apartment is around £125 for a gas boiler.
These savings are based on estimates from the Energy Saving Trust and may vary depending on the age and condition of the property, the type of boiler being replaced, and the specific energy usage patterns of the household. However, upgrading to an A-rated boiler can generally be a cost-effective way for households to reduce their energy bills and carbon footprint.
Energy Price Guarantee (EPG)
The Energy Price Guarantee (EPG) is a program initiated by the UK Government to help residents cope with the rising prices of gas and electricity. It provides assurance and relief to UK households by capping the maximum unit price for gas and electricity. This means that households will not be charged more than a certain amount for their energy usage, even if the market price goes up. The current EPG rates for households in the UK are 34p per kWh for electricity and 10.3p per kWh for gas. The EPG is designed to help alleviate concerns over rising energy bills and to prevent households from falling into fuel poverty.
However, without efforts to reduce energy consumption and improve energy efficiency, the annual energy bill for a typical household could still reach £2,500.
