Understanding ECO Grants

Energy Company Obligation (ECO) is a stupendous initiative by the UK government to reduce the country’s carbon emissions and at the same time help the residents upgrade their gas heating boilers. There are millions of households throughout the UK that are still using old, out-dated heating boilers that produce less heat but put tremendous burden on users in the form of energy bills.

The ECO initiative is here to change all this, under this scheme people on certain government benefits can now enjoy boiler replacement entirely free and in some cases partially free. And as boiler replacement is quiet costly, the ECO scheme has gathered a lot of attention and a positive response.

Attributes of ECO

  • The Energy Company Obligation (ECO) that took over from CESP and CERT in early 2013 requires the big six energy suppliers, to help householders become more energy efficient – an investment of almost £1.3bn is expected to be made by energy companies.
  • The ECO scheme is primarily focussed on helping low income consumers and those living in low fuel areas. The areas that are covered by the ECO grant include: period homes, blocks of flats or any brick built home without a cavity, or very small cavity.


  • Key components of ECO:
    Affordable Warmth Obligation: The affordable warmth obligation provides heating and hot water saving measures, insulation, glazing to low-income and vulnerable households. Call us on 08000-786-085 to check whether you may be eligible for the affordable warmth obligation.
    Carbon Saving Obligation:This provides funding to insulate solid-walled properties (internal and external wall insulation) and those with ‘hard-to-treat’ cavity walls.
    Carbon Saving Communities Obligation This provides insulation and glazing measures to people living in the UK’s most deprived areas.

What Type of a Boiler should you prefer?

While almost all gas heating boilers are covered in ECO grants, currently the Combination (combi) boilers are a major hit and everyone’s first choice.  Combi boilers are easy to install and take little space and they can also be hanged on a wall which makes them an excellent choice. If you have a small family and a medium sized residence then this is the boiler you need to get.

A combi boiler is simultaneously a high-efficiency water heater and a central heating boiler, hence justifying its name (combination). No separate hot water cylinder is required, offering space saving within the property.


  • Provides limitless hot water on demand.
  • Can be an economical option, as combi boilers only heat the water you use.
  • A great space-saving solution with no need for a separate cold water tank or hot water cylinder.
  • Installation may be quicker as there are fewer parts in a combi central heating system.


Different models of combi boilers are present on our website from where you can choose anyone and let us know. Our gas heating installers can also help you make a choice regarding which type of boiler suits you best.

We offer 1-year of aftercare on our boilers, so don’t worry about the new boiler installation as we will cover you for a year and service the boiler. One thing to remember is that you need to get your boilers serviced every year to keep them in working condition.

So, if you want heating advice, installation, maintenance or repairing, Domestic & General Heating is the company to contact. We strive to make your winters warmer.

Best boiler for your house

The performance of a boiler greatly depends on the size of the house and your heating/hot water needs. The best boiler for a one-bedroom flat will not necessarily be the same as the best boiler for a three bedroom, detached house. Here is a comparison between the best boilers for small, medium and large properties.


Best Boiler for a 1 and 2 bedroom house

If you have a one to two bedroom house, or flat, with only one bathroom then you will be best off with a small combi boiler. A small property will require a combi boiler of around 24-27kW. Here are some recommendations for the best combi boilers;

ManufacturerProduct nameTypeMax. central heating output (kW)Average price with installation*
BaxiEcoBlue+ 24Combi24£1584
Worcester BoschGreenstar 24i JuniorCombi24£1573
VaillantecoTEC Pro 28Combi24£1603


Best Boilers for a 3 bedroom house

Houses with three bedrooms and one bathroom can benefit from a range of boilers. A more powerful combi boiler (28-34 kW) is required. Conventional boilers can also be an option. It is best to talk to a qualified installer to receive the best advice.

These are our recommendations of the best boilers for a three bedroom house;

ManufacturerProduct nameTypeMax. central heating output (kW)Average price with installation*
VaillantEcoTEC Plus 837Combi28£1698
Worcester BoschGreenstar 34CDiCombi30£1786
BaxiSolo 30 HE AConventional30£1519
Worcester BoschGreenstar FS 30CDiConventional30£2170


Best for a 4 bedroom house

Large, houses with four bedrooms and above have higher heating and water demands and require a more powerful boiler. Typically combi boilers are not recommended here as they do not cope well with multiple showers/appliances using hot water simultaneously. A powerful combi boiler of 30kW and above may be suitable if that is your preferred option.
