Gas / Heating engineer

We have had 3 engineers visit over the last year (that’s the ones who turned up) and Iain is the first to give an honest account of the problem and then fix it on the day! Both Iain and his young apprentice were polite and well mannered, and more importantly, didn’t overcharge for the work.

I am extremely happy with the job Iain has done in fitting our new boiler. I have much appreciated his expertise and his professionalism, guiding me through the options. His work is excellent, he does what he says he’ll do when he says he’s going to do it and he’s a thoroughly decent guy. I would highly recommend him.

Iain did a brilliant job. He was friendly, enthusiastic and efficient. The heating system had never worked properly but thanks to his expertise it now does. Just in time as the weather is getting cold. I would highly recommend him.

Just had a new Grant boiler fitted by Iain and his team and he did a great job from start to finish. Firstly, communication was great, a massive let down with nearly all tradespeople in my experience. Very keen to quote then fall off the edge of the planet! Iain was consistently good at communicating throughout and his quote was clear and concise. We set an install date and he arrived with his team at 7.30am as promised. Job took 2 days as scheduled and they left with me being very happy. Thank you!

Iain Johnston - The owner of Evolved Energy Services attended my property which is being renovated. He inspected the old central heating system, recommended the best heating for my home. The work was carried out without me being at the property and Iain kept me informed throughout...which was fantastic...he updated me as the work progressed and advised me each step of the way. He was thorough with his paperwork and invoices were issued ‘detailing’ all works completed. Highly recommended! Thank you Iain.

Iain is a great example of a tradesman I wouldn't have found without Rated People. He tidied up the pipework for our boiler over the course of a day, was professional and knowledgeable, and offered a competative rate. I'll be sure to use his services again, and would recommend him to anyone.

Iain was great in helping us fix our boiler. He quoted us via video, came to undertake the works, and stayed in touch throughout. He was very responsive to my texts and went above and beyond his obligations to help us out. The works were not cheap, but they were done to a high standard and I have a lot of trust in Iain's workmanship. Don't hesitate to get Iain to help you!

I can’t rate Iain highly enough. He serviced the boiler and answered all my queries. Very professional and knowledgeable. To save me waiting in all day, he informed me he would phone me when he was on his way and, true to his word, he did. I highly recommend him.
