When Should You Replace Your Boiler?

For most homeowners, boiler replacement is something they don’t consider until their existing boiler starts playing up and causing problems on a regular basis. Some boilers will keep working for years and years in some homes with annual servicing and repairs when problems arise. But for some units, the cost and bother of getting them to work just isn’t worth it anymore.

If you have experienced:

  • Repeated repairs with no sign of your boiler improving
  • Increased energy bills
  • Decreased hot water performance
  • Odd noises or leaks coming from your boiler
  • Inconsistent heating on some radiators
  • Struggling to find spare parts
  • Own a boiler that is 10-15 years old or more
  • A boiler that has simply stopped working as well as it used to

…it may be time to start considering a replacement boiler.

Most boilers will last around 10-15 years if they have been well looked after (i.e. have received annual servicing and any problems have been addressed promptly). If your ageing boiler falls into this category and has started to lose its reliability, then the running costs of getting it repaired each time it breaks down can be worthwhile spending some time researching your options for a new boiler.

Unsure, start with our tool “Do I need to replace my boiler?” – it’s completely free and takes less than 2 minutes to get a result.

Repair or Boiler Replacement?

Boiler replacements aren’t always necessary when you have a fault. If it’s the first issue you’ve had with your boiler, a repair could still be the practical choice. Replacements tend to become more viable when repairs become more frequent, your old boiler is losing efficiency, or your central heating system is beginning to fail.

You should consider replacing your boiler if:

  • The cost of repairs is starting to mount up
  • It has needed repairing more than once
  • Parts are becoming hard to get hold of
  • The boiler is causing problems keeping your heating and hot water running
  • Your energy bills are too high because it runs inefficiently
  • You’d like a boiler that’s more energy efficient and comes with a better warranty

However, if your boiler is relatively new and the fault is relatively minor, getting it repaired can make more sense. But if your boiler is getting old and problems are more frequent, replacing your boiler with an efficient, reliable model is usually the best decision.

Boiler Repairs

The most common faults with Gas Boilers, Combi Boiler Systems and System Boilers include:

  • No Heat/Hot Water
  • Low Water Pressure
  • Leaks From The Boiler
  • Unusual Sounds
  • Inconsistent Temperature
  • Boiler Repeatedly Losing Pressure

If you see these signs in your boiler, you should get it checked as soon as possible.

Boiler Servicing

Annual Boiler service shelters you from serious risks with your boiler and helps maintain efficiency by keeping it safe to use, and also ensures your warranty remains valid.

Most major Boiler manufacturers advocate an annual Boiler service. It's also important to get your boiler serviced regularly because it:

  • Improves boiler efficiency
  • Ensures safe gas operation
  • Helps prevent carbon monoxide risk
  • Identifies wear before breakdown
  • Ensures the boiler is properly maintained

Regular servicing also helps ensure the boiler remains boiler safe and operating correctly while keeping the boiler warranty valid.

Benefits of a New Boiler

A new boiler can provide improved reliability, efficiency and comfort on a day-to-day basis. Installing a new condensing boiler in place of an old boiler can also reduce breakdowns and improve heating performance overall.

Benefits of a new boiler can include:

  • Heating and hot water you can rely on
  • Increased energy efficiency
  • Lower fuel bills for many homes
  • Improved controls and easier temperature regulation
  • Less noise
  • Brand new warranty
  • Elimination of future repairs
  • Better support for a modern heating system

Installing a new energy efficient boiler can help you make better use of the fuel you’re buying. An old G-rated boiler can be swapped for a new A-rated boiler to improve your heating system’s performance. According to the Energy Saving Trust, an A-rated boiler could save some homeowners up to approximately £300/year on heating bills*. Your savings could vary depending on your home and heating system.

*The savings you make will depend on your property, which boiler you’re replacing and how efficient your heating system is.

Choosing the Right Boiler

The right boiler depends on the size of the property, the number of bathrooms, hot water demand, available space and the layout of the heating system. Boiler replacement should not be treated as one-size-fits-all. Gas Safe registered engineers should assess the home and recommend the right boiler size and type of boiler based on how the property is used.

Important factors include:

  • Property size
  • Number of radiators
  • Number of bathrooms
  • Hot water usage
  • Available space
  • Existing heating controls
  • Whether the property has a hot water cylinder or a cold water tank
  • Water pressure and hot water pressure
  • Whether the property is connected to the gas grid

Boiler size is measured in kilowatts, and the correct output matters. Too small and performance can suffer. Too large and you may end up with unnecessary boiler cost and less efficient operation.

There is no single right answer from online boiler guides or boiler buying articles. The right boiler for one property may be completely wrong for another, which is why proper assessment is so important.

Boiler Types

There are several boiler types commonly used in UK homes, and the best option depends on the property and demand.

Combi Boiler

Combi boilers supply both heating and hot water from a single unit; therefore, there is no need for a separate cylinder to store the heated water.

The advantages of having a combination (combi) boiler include:

  • Space-saving and compact in design
  • Money saving
  • Best suited for households that have few people
  • The best option when space is at a premium

Combination (combi) boilers do not require separate hot water storage tanks, which saves space and can simplify installation.

System Boilers

System boilers are very common for larger Homes. They are usually paired with a hot water cylinder and are perfect for:

  • Multiple bathroom houses
  • High demand for hotter water
  • Larger families
  • Any home where a higher heat output is required

System boilers store water in a cylinder for future use (allowing multiple taps to be used at the same time without causing loss of pressure). System boilers are often paired with an unvented hot water cylinder that can support greater performance of hot water in Homes where high demand exists.

Regular Boilers (Conventional Boilers)

Regular boilers – also known as conventional boilers or heat-only boilers – are often found in older houses and homes.

These types of boiler systems use:

  • A hot water cylinder
  • Cold water storage tanks
  • Traditional heating system layout (often a cold water storage tank is located in the Loft)

Heat-only boilers work in a similar way to system boilers. Regular boilers are suitable where the same type of heating system already exists, and replacing like-for-like can sometimes reduce installation changes.

Electric Boilers

An electric boiler is an alternative to using a gas boiler. These units are ideal when there is no gas connection to the property or to the mains gas supply.

Generally, electric boilers are small and therefore take up less space. Additionally, electric boilers are also generally quiet. They can make great alternatives for flat dwellers and those living in small homes.

Costs associated with using electricity to power these boilers will generally be more expensive than using a gas fired boiler.

Oil Boilers

Oil boilers are often found in rural locations where there is no mains gas supply. They require on-site storage of oil and regular refills of the oil container.

LPG Boilers

LPG Boilers are an alternative for houses that do not have access to the mains gas supply. LPG Boilers function like a conventional gas boiler but require periodic refilling of the LPG storage tank.

Heat Pumps and Low Carbon Heating Systems

Some homeowners are exploring heat pumps as part of a low carbon heating system.

While boilers remain the most common heating solution across Great Britain, we are happy to discuss alternative options if appropriate for your property and usage.

Hydrogen-Ready Boilers

Some new boilers are described as hydrogen-ready.

These boilers can operate on natural gas now. They can be converted later if the gas grid transitions to hydrogen in the future.

Still unsure? Take our quick test and see what boiler is right for your home.

 

Boiler Replacement and Heat Pumps

A number of homeowners considering a new boiler also find themselves asking about heat pumps. A heat pump can play a role in a low carbon heating system and may help you reduce carbon emissions if you have the right property. It won’t suit every home. But where you are considering replacing your boiler and thinking about longer term plans to move to low carbon heating, it’s worth at least discussing.

For a lot of houses, a heat pump really shines when it’s paired with its own hot water tank and the heating setup is properly planned or modified. That’s why some households opt for installing a system boiler or conventional boiler setup when planning future-proofing their heating, rather than going straight to a combi boiler.

When weighing up the options between a replacement boiler or heat pump, there’s no cut and dried answer. It will depend on your property, how well insulated it is, how much space you have and how much hot water you need, plus your budget.

What Is Included in Boiler Replacement?

Boiler replacement usually involves more than simply removing the old appliance and fitting a new one. A proper boiler installation should include assessment, safe removal, checks on the system and correct commissioning.

A typical boiler replacement may include:

  • Removal of the old boiler
  • Installation of the replacement boiler
  • A system flush where needed to clear debris from the heating system
  • Pipework alterations were required
  • Flue installation or adjustment
  • Setup of heating controls
  • Room thermostat checks
  • Time and temperature controls in line with Boiler Plus
  • Thermostatic radiator valves where required
  • Safety checks and testing
  • Commissioning of the new boiler and certification

For gas work, it is illegal and unsafe for anyone other than Gas Safe registered engineers to fit a gas boiler. 

Boiler Installation Timescales

Boiler installations or boiler replacements usually take between one and three days, depending on the level of complexity. A like-for-like replacement boiler installation will usually be quicker than changing to a larger boiler.

Factors affecting installation timescales include:

  • Whether you’re moving the position of your boiler
  • Whether any pipework needs replacing
  • What type of boiler are you getting replaced with
  • The age and condition of your existing heating system
  • Whether you’re using a hot water cylinder or a cold water tank.
  • If heating controls are being upgraded as part of the installation

We will explain the likely timescale before work starts so you know what to expect.

Boiler Replacement Cost

Boiler replacement cost can vary widely depending on the type of boiler, the size of the appliance, the complexity of the work and the condition of the existing system. As a broad guide, total boiler replacement with installation can range from around £3,000 to £15,000 depending on the type of property and work involved. In comparison, the boiler price alone can range from around £500 to £3,500 before installation.

What affects boiler replacement cost?

  • Type of boiler
  • Boiler size
  • Labour involved
  • System upgrades
  • Pipework changes
  • Whether a hot water cylinder is required
  • Controls and thermostatic radiator valves
  • Whether the installation is straightforward or more complex
  • Property layout and access

Prices will differ dependent on a number of variables, so the best option is to book your survey and ask for a fixed quote. We try to be as upfront with our boiler quote as possible, so you know what you are getting. If you have been searching online for boiler quotes or attempting to find out how to compare a boiler online, make sure you still get the property surveyed correctly, as standard prices aren’t factored with real installation scenarios.

Boiler Warranty, Boiler Service and Ongoing Care

When you replace your boiler, it will often come with a manufacturer’s warranty. Nowadays, boilers come with warranties from approximately 1 year up to 10 years. It depends on the appliance, manufacturer and terms of installation.

Typically, the warranty is conditional upon yearly servicing. So it’s essential to have your boiler serviced every year and ensure that your records are kept. The cost of boiler service isn’t part of the installation costs. Still, it’s worth doing to maintain your investment and ensure your boiler runs efficiently for years to come.

We can also offer guidance on servicing, boiler cover and maintenance to keep your boiler running after it’s been replaced.

Boiler Replacement FAQs

Support programs are frequently changing, typically covering more comprehensive energy efficiency or greener heating improvements, not just standard boiler swaps. Check eligibility and scheme details at the time you intend to do the work.

Provided it's well maintained and serviced on a regular basis, a new boiler will typically last 10 to 15 years, sometimes longer.

No blanket answer will apply to every home. The trickier question to answer is which combi boiler is the best option for your property. The wrong combination boiler will typically be one that's not suited to your home's demand for hot water, pressure or general layout.
