Waste of time applied for the government grant to be told my household does not meet their requirements, even though it clearly states on their website that qualifying benefits and a old aging boiler that is over the age of 16 years old that does not work and left a venerable household with a 9 month old and 2 over 60s who are vulnerable and with many health conditions with out the appropriate boiler and heating system. Even though on their website it clearly states qualifying benefits and those with children and the elderly who are over the age of 60 with government funding but No just more lies and misinformation. They should definitely change what they have put on their website as it is misleading

Hi Hamzah,
We're sorry to hear that you were disappointed with the outcome of your application.
The ECO4 scheme is a government-funded scheme with strict eligibility criteria that all installers must follow. While qualifying benefits and household circumstances are important, the property and existing heating system must also meet the scheme's technical requirements.
Although older boilers qualify for replacement in the vast majority of successful ECO4 applications, this is not a guarantee in every case. Eligibility is assessed against the full scheme criteria, not on the age of the boiler alone. Our website explains the general eligibility requirements but does not state that every applicant, or every older boiler, will automatically qualify for a free replacement.
In your case, your property already has a Worcester Greenstar condensing boiler. Under the ECO4 scheme rules, a condensing boiler cannot normally be replaced with another condensing boiler, as doing so would not provide the energy efficiency improvement required by the scheme. This is a government funding rule that applies to all ECO4 installers, not just our company.
We genuinely sympathise with your family's circumstances and understand your frustration. Unfortunately, we cannot approve work that falls outside the scheme rules. We will, however, review the wording on our website to ensure the eligibility criteria are as clear as possible for future applicants.
We wish you and your family all the very best.
Kind regards,
Heatzen
Had the survey completed
Had the survey completed, no contact from them, upon chasing they made a lame excuse about my 83 year old elderly mother.
Therefore I have had no other option but to pay someone else £3700 funded by myself to ensure my Mum has hot water and heating.
Shocking!

Hi Carol,
We're truly sorry to hear about your experience and understand how stressful this must have been, especially with your elderly mother needing reliable heating and hot water.
As this work is carried out under a funded scheme, we are required to meet strict eligibility and financial viability criteria before a fully funded installation can proceed. In the vast majority of cases, customers receive the work completely free of charge. However, in some instances where the funding does not cover the full cost, a small customer contribution is required to make the project financially viable.
In your case, we discussed the possibility of a contribution. Before we were able to reach an agreement, you chose to arrange the work independently and paid the full cost yourself.
We genuinely regret that we couldn't achieve a better outcome and would still welcome the opportunity to discuss your case further if you're willing to speak with us.
Kind regards,
Heatzen
Put the wrong size boiler in so been condemned by BG and the manufacturer this date is last contact with proximus
Shocking not sure if these where originally called Heatzen this is the name they used when they recently rang Heatzen is who originally installed our boiler but they installed a boiler to big for the cupboard blamed me saying I asked for the boiler but im not the engineer if it doesn’t fit then they should have said it couldn’t be installed now they want me to cut out my cupboards plinth so it would be able to be serviced. I said no and they left it there saying they would come back to me but they have vanished off my WhatsApp, getting on 2yrs the manufacture said they have put on the system that tge warranty with them is void and I took a payment plan out with British Gas and they put warnings on it so who is bringing these people to account for what they do to people it’s a disgrace. Maybe I should get the boiler replaced snd tgen gp through small claims and they do the government grant ones do maybe if anyone knows someone in the DWP who pay these cowboys ask them to take them off the list, there should be some system to make sure these people don't keep ripping people off but they should never be able to claim the grant money or anyone’s money until customers are happy.

Hi Shirley,
We are sorry to hear you remain unhappy with your experience.
We would like to clarify that this installation was completed some time ago, and when concerns were raised, we did not ignore them. We arranged for an engineer to attend and review the situation, and we also discussed multiple possible solutions with you, including options around the cupboard and relocating the boiler. At the time, we also made it clear that we were willing to cover the cost of an agreed solution so the matter could be resolved.
Unfortunately, the available options required either cupboard alterations or relocation work, and we understand these options were not suitable for you at the time. As a result, the matter was not able to move forward.
We also need to clarify that our workmanship warranty period is 2 years, and this matter is now being raised again after a significant amount of time. However, we still take all concerns seriously and remain willing to review the case and discuss what reasonable support may still be possible.
We are sorry that you feel let down, but we do not agree that we vanished or refused to help. Our previous communication shows that we offered solutions and asked for your agreement on how you wished to proceed.
Please contact us directly so we can review the full history of the case and advise on the next steps.
Kind regards,
Heatzen

Provides false information that ECO4 grant is only for old non-combi boiler. When questioned the salesman started shouting at me. Could be rogue traders in the industry.

Hi Mika,
We appreciate your feedback, although we're puzzled as we couldn't identify you as one of our customers. To help us investigate this matter properly, could you please provide evidence that you have dealt with Heatzen?
Regarding the ECO4 scheme, eligibility is determined by a range of factors and not solely by whether a property has a combi or non-combi boiler. Assessments are based on several criteria set out within the scheme requirements, and each case is considered individually.
We are committed to providing excellent customer service and take all feedback seriously. However, it is important that reviews accurately reflect genuine interactions with our business. We would appreciate your cooperation in providing further details so that we can investigate and address any legitimate concerns.
We look forward to hearing from you.
Kind regards,
HeatZen
