In the last few months the UK  committed to meet a target of net zero carbon emissions by 2050, but is it possible? This doesn’t mean ridding ourselves of all carbon-producing appliances and items. Instead, the amount of carbon pumped out into the atmosphere must be no more than the amount taken out from 2050 onwards. The policy means that everyone will have to think long and hard about the way they live their lives, and the type of boiler you use makes a big impact on your net carbon emissions.

Boiler Efficiency

There is a stark difference between the efficiency of old boilers currently installed in many homes and businesses across the UK and the emissions produced by the new, much greener models on the market.


For example, the Worcester Bosch Greenstar 9i System ErP runs with an efficiency of 94%, meaning that only 6% of the fuel used to run the boiler is released into the environment. The other 94% is converted into the heat that warms your radiators and water. Anything over 90% receives an Energy-related Products (ErP) A-rating for efficiency. Alternatively, G-rated boilers are those that score less than 70%, meaning that around a third of energy is wasted when you run your central heating and hot water. Because it is so inefficient, it needs to eat up more energy just to achieve the same amount of heat as an A-rated appliance.

Modern boilers are usually all condensing boilers too, which aids efficiency. The condensing system makes use of the flue gases that would otherwise escape into the atmosphere in order to provide heat. If you have an old, non-condensing boiler fitted in your property or workplace, it is worth looking to replace it.

The best boiler companies only sell and install the latest and most efficient boilers around, as the benefits to both customers and the environment are hugely important considerations.

Benefits of Efficient Boilers

There are two main benefits to installing an efficient new boiler:

  • Saving money on your energy bills.
  • Reducing carbon emissions into the atmosphere.

The less energy needed to run a boiler, the lower your energy bills. Whether it is a natural gas boiler, oil fired boiler or LPG boiler, if you use less fuel on top of that which provides the heat, you will earn decent savings. This is why boiler companies survey homes before they recommend the ideal boiler for the property. You have to strike a balance between the power needed to provide all the heat and hot water the family needs without installing something too powerful that becomes ultimately wasteful.

This higher efficiency means that the net carbon emissions are as low as possible. If people who are still running boilers with a peak of just 70% efficiency move over to a new model, that would be a huge step towards the country striving to hit those net zero carbon emissions by 2050.

The real positive is that the situation is a win/win. Householders and business owners save money and help the environment at the same time. There is no difficult choice to make like there might be in other areas of our lives. Cutting net carbon emissions from the food industry could mean having to do without favourite foods because they have to be transported from far away. When it comes to transport, we might need to forgo the convenience of the car and use patchy public transport in order to hit that net zero target. However, there is no downside to installing a new and efficient boiler.

Government ECO Grants

Of course, to make use of a new model of boiler, you need to be able to afford one. The good news is that the government offers grants through its ECO scheme. ECO stands for Energy Company Obligation, so named because large and medium energy firms are required to set aside funds to help tackle fuel poverty and reduce carbon emissions.


This means that they have to make it easier for those on low incomes, fuel poor households and the vulnerable to attain savings on their heating bills. One of the best ways to achieve this end is to help these groups buy new energy efficient boilers and heating systems.

Of course, as the number of homes with new, better-rated boilers increases, so the carbon emissions reduce, helping ECO make a real difference in both of their target areas.

ECO Funding

Boiler installers can contact obligated energy companies for the chance to offer their customers access to the government ECO grants on offer. Each individual customer’s case is different, but generally you will qualify for help from the ECO scheme if you receive one or more of this range of benefits:

  • Child Tax Credit
  • Working Tax Credit
  • Universal Credit
  • Pension Guarantee Credit (not eligible if the customer only claims Pension Savings Credit)
  • Income Support
  • Income-based Job Seekers Allowance (JSA)
  • Income-related Employment & Support Allowance (ESA)
  • Disability Living Allowance
  • Personal Independence Payment (PIP)
  • Attendance Allowance
  • Carer’s Allowance
  • Severe Disablement Allowance
  • Industrial Injuries Disablement Benefits
  • War Pensions Mobility Supplement
  • Constant Attendance Allowance
  • Armed Forces Independence Payment
  • Child Benefit

Clever Energy Boilers and Net Zero Carbon Emissions

At Clever Energy Boilers, we are passionate about supporting householders and businesses in cutting their energy bills and reducing their carbon emissions. We can advise on seeking government ECO funding as well as helping you find a boiler financing plan that works for you.

If the UK is going to hit its target of zero net carbon emissions by 2050, it is important that as many people as possible move away from gas guzzling boilers that are only costing households an unnecessarily large amount of money each month just to operate. The more people who switch to the latest green boilers by the likes of Worcester Bosch, the more chance we have of making this bold aspiration a reality
