Get ready for winter with a boiler upgrade

As winter approaches, making sure that your home is warm and comfortable becomes a top priority, and one of the best ways to achieve this is with your boiler. If you're facing issues with an ageing boiler or considering a more energy-efficient option, an electric boiler upgrade might be the solution you need. 

But with so many options to choose from, how do you know which boiler to pick, and which one is the best price for you?

Factors that influence the cost of a new boiler

Boilers can be expensive, and they can vary considerably depending on the type, style, energy efficiency, and the size you choose. 

Boiler type and size

The type and size of the boiler you choose will play a significant role in determining the overall cost. Combi boilers, system boilers, and conventional boilers each have their advantages and price ranges. If you live in a larger home, you may require a more powerful boiler to meet heating demands, which can affect your overall cost.

Efficiency rating

If you opt for a highly efficient boiler, this might increase the initial cost but it can significantly reduce your long-term energy bills. High-efficiency boilers not only provide better performance when it comes to heating your home, but it can also contribute to a greener environment by reducing carbon emissions.

Installation complexity

The complexity of the installation process can impact the cost of your boiler. If your home's existing heating system requires extensive modifications, or if you need to replace old pipework, the boiler installation cost may be higher.


Your geographical location can also influence the cost of a new boiler. This could include things like local labour rates, availability of materials, and local regulations. All of which  can  play a role in the final price of your new boiler.

To determine the exact new boiler cost for your home, it's advisable to shop around with SpotDif to compare multiple reputable heating engineers, making sure you find the right boiler for your needs. This will allow you to look at different prices and make an informed decision before you proceed. 

The benefits of a boiler upgrade

Investing in a boiler upgrade for your home offers several compelling benefits that extend beyond cost considerations. Here are some reasons why upgrading your boiler is a wise choice.

Improved efficiency

Newer boilers are designed to be more energy-efficient, which can lead to substantial savings on your energy bills. They use advanced technology to heat your home more effectively while consuming less fuel.

Enhanced reliability

Older boilers are prone to breakdowns and require frequent repairs. Upgrading to a new boiler reduces the risk of inconvenient heating failures, providing you with peace of mind during the winter months.

Eco-friendly operation

Modern boilers are designed to be environmentally friendly, emitting fewer greenhouse gases and pollutants. By upgrading, you contribute to a cleaner and greener future.

Better performance

New boilers often come with advanced features, such as digital controls and programmable thermostats, allowing you to have more control over your heating system. This results in better comfort and convenience.

Longer warranty

New boilers typically come with longer warranty periods, ensuring that you are covered for any unexpected issues. This can save you money on future repairs and maintenance.

Is replacing a gas boiler a viable option?

As the world becomes more environmentally conscious, you might be considering the switch from gas to electric heating systems. This transition aligns with the worldwide goal of reducing carbon emissions and minimising our reliance on fossil fuels. 

If you're contemplating replacing your gas boiler with an electric one, here are some important considerations to think about before you look at replacing your old gas boiler. 

Installation flexibility

Electric boilers are generally easier to install than gas boilers. They don't require a flue or a gas supply, making them suitable for a wider range of properties, so this is perfect for you if you live in a flat or your home doesn’t have a gas connection.

Running costs

While electric boilers are efficient, electricity can be more expensive than natural gas in some regions in the UK. Before you commit to either a gas or electric boiler, it's essential to compare the running costs of electric and gas boilers in your area to determine if the switch makes financial sense.

Availability of renewable energy

If you have access to renewable energy sources, such as solar panels or wind turbines, using electricity for heating becomes even more environmentally friendly and cost-effective.

Before deciding to replace your gas boiler with an electric one, consult with a heating professional to assess your specific needs and calculate the potential savings and environmental benefits.

How to buy and choose a new boiler

When it comes to buying a new boiler, making the right choice involves careful consideration of various factors. Still a bit confused? Here's a step-by-step guide to help you navigate the process of choosing the right boiler for your home. 

Assess your heating needs

Begin by evaluating your heating needs. Consider factors like the size of your home, the number of occupants, and your hot water requirements - what’s the demand like? This key information will help you determine the type and size of the boiler that’s right for your household. 

Choose the right boiler type

There are three main types of boilers: combi boilers, system boilers, and conventional boilers. Each has its pros and cons, so it's essential to select the type that aligns with your requirements and budget.

Research brands and models

Not all boilers are created equal. Research reputable brands and models known for their reliability and efficiency. Reading customer reviews and seeking recommendations from heating professionals can be invaluable during this stage.

Consider efficiency ratings

Opt for a boiler with a high efficiency rating, as this will result in lower energy bills and reduced environmental impact over time. Look for boilers with the ENERGY STAR label or a high AFUE (Annual Fuel Utilisation Efficiency) rating.

Installation and maintenance

Choose a qualified and experienced heating engineer for the installation of your new boiler. Additionally, inquire about maintenance packages to keep your boiler running smoothly and efficiently.

Financing options

Explore financing options if you need assistance covering the upfront cost of your new boiler. Some companies offer financing plans with flexible terms to make the investment more manageable.

Consider long-term savings

While the initial cost of a new boiler may seem high, it's essential to consider the long-term savings in terms of reduced energy bills and fewer repair expenses. A high-quality, efficient boiler can easily pay for itself over time.

Are there government incentives or rebates for boiler upgrades?

The UK government offers a Boiler Upgrade Scheme for households looking to replace their existing boiler with a more energy-efficient option. You might be eligible for a grant to offset expenses associated with the replacement of fossil fuel-based heating systems with either heat pumps or biomass boilers. Fossil fuel heating systems include oil, gas, or electric options. 

To qualify for a grant under this scheme, there are a few straightforward conditions to meet. First, you should be the owner of the property you're seeking assistance for, whether it's your primary home, a business location, a second residence, or a rental property. Secondly, your new heating system should have already been installed on April 1, 2022, or later. 

It’s important to note that the heating system you're replacing should be one of the older fossil fuel types like oil, gas, or electric. But the good news is that even if you've received funding in the past to boost your property's energy efficiency, such as adding insulation, you're still eligible for this grant.
