When Is It Time for a Replacement Boiler?

There are multiple warning signs your old boiler can show that might mean it’s time to think about planning a boiler replacement.

Rising Energy Bills

If your current boiler is resulting in costly energy bills each month, a modern boiler may be an efficient option that outweighs any boiler replacement costs with lower energy bills that don’t break the bank.

Frequent Boiler Breakdowns

If you’re experiencing multiple breakdowns or constantly booking boiler repairs, a boiler replacement might be a more cost-effective option to consider, especially if you don’t have any boiler cover or annual boiler service plan in place.
If you smell gas at any point, please contact the National Gas Emergency Service immediately on 0800 111 999.

Unreliable Heating and Hot Water

If your boiler output and your heating system lack consistency, a replacement boiler might be required to ensure heat and hot water for your home on a reliable basis.

Outdated Heating System Technology

If your current gas boiler uses old-fashioned, outdated technology, a new boiler replacement can offer the added benefit of advanced features like smart controls or enhanced energy-efficient solutions.

What’s the Best Boiler for You?

The best new boiler for your home will depend on many factors, including space, cost and performance.

Combi Boilers

Combi boilers are an efficient choice that provides central heating and hot water directly from the mains, removing the need for a separate hot water tank.

See Combi Boiler Prices

System Boilers

System boilers are a preferable choice for larger homes with more than one bathroom but aren’t the best choice if you have low water pressure. System boilers require a hot water tank to allow for the provision of higher volumes of hot water.

See System Boiler Prices

Conventional Boilers

Conventional boilers are a traditional type of gas boilers installed in older homes. They require both a cold water tank and hot water cylinder to heat your home, meaning they take up more space than more modern boilers and aren’t the most efficient choice.

Condensing Boilers

Condensing boilers are the most common type of gas boiler in the UK. They are connected to the national grid, utilising hot gas passing through a central chamber to heat up water.

Boilers on Finance

If you need help with boiler replacement costs, you may be able to take advantage of our new boiler finance options. Depending on your status, credit checks and successful finance application, we can offer interest-free boiler finance or a standard finance plan for your new boiler, making it easier than ever to replace your boiler with a new, energy-efficient model.

Excellent service from James Frew. We have been with them for at least 10 years and they are efficient and friendly. Our boiler is serviced by them on an annual basis with no issues and we had plumbing cover and the one time we needed them for a minor issue it was fixed quickly without any big wait that you get with some tradesmen. Also no hard sell from them everytime they service the boiler as we got with another major company. Highly recommended.

I contacted James Frew. Gas Sure for their Gold Home Care plan. Everyone was helpful and informative. Julian completed the initial inspection of our boiler/radiators and he was polite and informative explaining everything he was doing. I'm really happy with the cover I get from the Gold plan and happy with the price.

Julian the engineer who inspected the boiler was quick, professional and knowledgeable when asked questions. The silver home plan is excellent value for money and provides peace of mind should anything go wrong.

Boiler Replacement FAQS

How much should it cost to replace a boiler?

Your new boiler cost will differ depending on many factors, including the boiler type you’ve chosen (e.g. Combi Boiler, System Boiler, Conventional Boiler) and the boiler brand, as well as any installation costs that accompany the new system.

We know that a replacement boiler can be an unexpected expense, which is why we offer flexible financing options to make it easier, including low-interest finance and 0% interest-free credit options to help make the boiler and installation cost more manageable.*

*subject to status and credit checks.

Can you get a grant for a new gas boiler?

Yes, some homeowners may qualify for boiler grants under Government-led energy efficiency schemes. Eligibility depends on your household income, whether you receive certain benefits and the energy efficiency of your current boiler. The ECO4 Scheme offers financial support towards a new boiler for lower-income households, whilst the Home Energy Scotland Grant and Loan Scheme can provide a grant or interest-free loan to help with the costs of installing a new heating system and other energy efficiency measures.

Is replacing a boiler a big job?

Boiler installations can vary in the length of time required depending on the new boiler you’ve chosen and where this will be installed in your home.

If your new boiler is being fit in the same place as your old boiler, it can take an engineer around a day to fit this. Additional time will be required if you require your new boiler to be installed in a new location, due to changes to pipework being needed as well as additional time for testing that your new boiler is working as efficiently as possible.

Should I replace my 20-year-old gas boiler?

Most boilers last 10-15 years with regular servicing. It may be time to get a new boiler if:

  • Your boiler is over 10 years old and less efficient.
  • You’re frequently paying for repairs or breakdowns.
  • Your heating bills are increasing despite no change in usage.
  • Your boiler is leaking, noisy or struggling to heat your home properly.
  • You want to upgrade to a more energy-efficient model and reduce your carbon footprint.

If you’re unsure, our expert engineers can assess your current boiler and recommend the best option for your home, whether that be a combi boiler or another gas boiler installation.

Do I need to replace my gas boiler?

As of now, there is no gas boiler ban legislation demanding that homeowners should replace gas boilers.

Recent reports indicate that plans to ban the sale of new gas boilers by 2035 have been scrapped, allowing homeowners to continue using and installing new gas boilers beyond this date.

While there is currently no legal requirement to replace your gas boiler, upgrading to a more efficient model can enhance your home’s energy efficiency and reduce utility bills.
