With a grant of 78% you'd be stupid not to get your property upgraded. You end up with a warmer home and cheaper fuel bills. Also, if needed a interest free loan.

We started our journey in December 2025 applying for our grant monies. The process was very smooth, the customer service from the team was excellent. Even though this was happening through the holiday season, the draw down monies were paid in to my account in the 2nd week of January and the remainder in the first week of February after our ASHP system was installed. The experience was first class, the help and support was excellent and the process was very smooth and I'm very happy....Many Thanks Energy Saving Trust

I will never recommend this grant and loan to anyone. it may sound appealing but its a joke from start to finish. If I felt getting approved was a challenge i had no odea what i would face when it came to making a claim. every excuse under the sun not to pay out. hurdle after hurdle. sometimes weeks between responses to your queries or questions. there is absalutely no need for this to be as difficult as this. It has wasted not hours but days of my life that I will never get back. typical government designed scheme pulled together by people with some degree but not one single ounce of common sense.

Double-Glazing Loan Helped A Lot
We applied for an interest-free loan to pay for our new double-glazed windows and were super happy with the help we got from EST. The application process was fairly straightforward. I opted to communicate via email with the team which made it easier for me. The application portal worked well for me and I was delighted with how quickly our application was processed and later on, how quickly we received the loan amount. Would definitely recommend!

Very Quick, Easy and Fairly Smooth Process
Apart from a minor issue with the online form and me having to fill out an emailed form and then upload it, the process was very quick and went pretty smoothly.
After uploading the completed form with my bank details, the grant was received 4 days later.
From start to finish, including getting advice from Home Energy Scotland, quotes from suppliers, the installation work completing, the grant money being received and my proof of payment being accepted, it was just over 3 months.
Home Energy Trust Scotland were very quick to answer by phone and respond by email.

Helpful and efficient
In contrast to some of the other reviewers, I found the EST website and grant/loan forms pretty easy to navigate, and replies were quick and informative. Without the support of the EST, I'd still be polluting the environment with my dirty oil boiler.
Oh, and a tip for those who complain about spam/scam calls - not everybody who calls you on the phone is who they say they are. ;-)

Suspicious, Unprofessional Company
Had a call from this company today
(01597481012) claiming to work for/ with the government. The woman was very cagey about giving any information out but wanted personal information from me. She wouldn't even say where she was based. Add to that I'm registered with the Telephone Preference Service which they obviously hadn't checked when cold calling I find them very unprofessional and very suspicious.

Trying to apply for a car charger…shambles.
Trying to apply for a car charger grant. The installer was approved about 10 days ago. But still isn't selectable on the grant form. They advised him it would be 'a few days' before he appeared but if I wanted to apply I could just select 'other' on the form and put his name in manually. There is no option to do this. I've called them and been passed around, given 3 numbers before getting to the right department, for the call not to be answered. Then got what I believe was the correct number to call in the end, and was advised by staff that they're really busy but if I leave my name and number they'll get back to me within 8 working days!
I'd complain, but the complaint e mail address is the same one I e mailed about this whole thing, from which I've had no reply. Although it says if you complain they'll reply within 2 working days. If they can reply to complaints why not just actually reply to queries in this time and prevent complaints!

Worst application process in existence.
Worst application process in existence.
Literally just gave up applying for their IT Support Analyst position because of the amount of really silly questions it asks.
Why do you need to know my dad's employment status in the 80s? Why do you need to know if I had free school meals? You have zero right to ask such nonsense.
Your application process is so far put of date it's actually an insult to ask anyone to fill it out.
If you're serious about filling that role then you can accept my CV

Hi Paul,
Thank you for your feedback and for sharing your experience with our application process. We’re sorry to hear that you found it frustrating.
As part of our commitment to Equity, Diversity and Inclusion (ED&I), we ask certain voluntary questions, such as those about parental occupation and eligibility for free school meals to help us understand and address barriers that people from different socio-economic backgrounds may face. This data enables us to improve fairness in recruitment and progression, and to ensure our opportunities are accessible to everyone. These questions are recommended by the Social Mobility Commission.
However, we completely understand that not everyone will feel comfortable answering these questions, which is why each one includes a 'Prefer not to say' option. We’re reviewing how we communicate the purpose of these questions more clearly, and your feedback will help us do that better. Please be assured that any data you provide is treated in the utmost confidence, kept separate from your application, and has no bearing on selection decisions.
That said, we recognise the current system can feel outdated and time-consuming. We’re actively addressing this and will be implementing a new recruitment platform this autumn to make the process much clearer, quicker and more user-friendly.
We appreciate your interest in Energy Saving Trust and your feedback, which helps us improve.
Best regards,
Recruitment Team
