What is the ECO4 scheme Wales?

The Energy Company Obligation (ECO) Scheme, also known as the ECO4 scheme, is a government-driven initiative commonly referred to as the “free boiler scheme.” It mandates major energy suppliers like British Gas, EDF, and SSE to support low-income and vulnerable households by replacing inefficient or broken boilers and improving insulation.

To seize the benefits of the government’s ECO4 scheme, it is imperative to assess your eligibility before it’s too late. If you qualify, this scheme provides a wide range of energy efficiency measures at significantly discounted rates or even for free. These measures encompass boiler replacement, external wall insulation, cavity wall insulation, and more.

Will my free boiler Wales come with warranty?

Your newly installed boiler, irrespective of the selected brand (whether it’s free or contributed), will be accompanied by a standard two-year warranty. If you desire an extended warranty, you can directly contact the supplier to discuss the nominal cost of a five-year warranty.

Will I pay anything with a boiler grant Wales?

In general, there are only two scenarios where a small contribution may be required. Firstly, if you opt for a Worcester Bosch or Vaillant boiler instead of the Ideal Logics that we install, a slight contribution may be discussed due to the higher cost associated with these premium brands.

Secondly, if your household’s current boiler fails to meet gas safety regulations, certain adjustments may be necessary to comply with the checklist. However, rest assured that each situation is unique, and any required contribution will be openly discussed with you.

What happens if something gets damaged?

All our skilled workers take great pride in their exceptional craftsmanship and are fully insured. However, in the unlikely event of damages caused by our contractors, we will promptly replce the affected items, ensuring your complete satisfaction.

How long does the process take from initial contact to installation?

We aim to ensure a speedy and efficient installation process. From the moment you reach out to us, our dedicated team will work seamlessly with you until the installation is completed. To expedite the process, please provide us with the necessary information promptly, allowing us to complete the installation without any delays.

Will it be a like for like replacement?

While the brand may vary, you can rest assured that the replacement boiler will match the performance and power of your current one. In fact, our new boiler will offer enhanced efficiency, resulting in significant savings on your gas bills.

Do you qualify?

Wondering if you’re eligible? Finding out if you qualify for boiler funding under the government ECO4 scheme is easy. Simply answer the following questions:

  1. Are you a homeowner? 
  2. Is the bottom floor of your household suspended flooring (made up of floorboards and NOT concrete)? 
  3. Does anyone in the household claim benefits/tax credits (please see the list of benefits that qualify and ensure that one is claimed within the household)? 
  4. Is your boiler 7 years old (or older)?

If you answered YES to all of these questions, then you apply for free boiler replacement and installation.
