Great way of delivery training….

We have been using Gas Certifcation Company for many years and cannot fault it, Andy and his team have a great way of delivering the training and a wealth of knowledge in the industry, we have just completed our reassessment for our commercial tickets. I highly recommend this training centre and will continue to use in the future (back in September for LPG)….

The only place to go for your training !

I've been attending Gas Certification Ltd for many years now since its inception and the business just goes from strength to strength and has a good vibe around the place.

The training and admin staff are very welcoming and professional in everything they do and they make the training process an enjoyable experience.

Andy, Joe and Tam have vast technical experience across the industry and their methods of teaching although thorough and covering all the necessary details are done in a way to make even the most nervous of trainees feel confident and relaxed which goes a long way to getting the courses passed.

The centre has gone through a massive transformation over the past year and they have invested heavily in all areas of the business and the centre is looking great, with many new training areas constructed, future-proofing the business with renewables training now being provided.

Good luck for the future and thanks again for getting me through my domestic/commercial gas and unvented hot water courses.

Rewarding experience.

Rewarding experience.

The Gas certification company has always been a very professional set up.
I have recently completed my training and assessment on LPG & NG.
The training has been improved and is geared to not only preparing for assessment, but to help candidates learn and retain new and existing knowledge.
I completed this years assessment being able to retain more knowledge than in previous years.
This isn't a criticism on last years assessment process but merely to point out that there has been positive improvements in this years training.

A very polite, friendly and professional environment.
Andy and Joe are amazingly passionate about the job they do and are continually focused on candidates being fully prepared for assessment.
Gayle has the patience saint and her efforts didn't go unnoticed or appreciated by all the candidates.

I always felt the centre was first class and I was delighted to find it has somehow manage improve again.

Thank you to everyone for making it a very rewarding assessment.

Best ACS since passing my very first!

Recently undertook my resit of changeover domestic to commercial at the centre, having used them before I was always expecting a good experience but was unsure this time due to the change of management.
It was fantastic to see the team have kept the legacy of George as a core to their being, the experience was once again fantastic with the training staff very knowledgable and approachable the office staff really went above and beyond to make you feel welcome and comfortable and the facility it self is very modern it certainly doesn’t feel like any other “training school” or college I have used before.

Massive shout out to Gayle for her amazing patience with our course she handled everything we could throw at her and even sent us the kitchen sink! To Jo for her super relaxed attitude over assessment and guidance to get the knowledge out she knows you have, to Tam for his nuggets of info and to Andy for his (well usual) enthusiastic attitude to the industry.

Even the other Ladies in the office create a great experience and certainly keep this lot on their toes seamlessly.

Will certainly be using them again and maybe even sooner than a resit with the course’s they are building up to make our industry stronger in Glasgow and the west.
