Tom, Optima Gas Engineer

The engineers turned up on time,worked a very long day with consideration and competence and were most reassuring when an unforeseen problem arose. I would have no hesitation in recommending them and using the company again….

Mrs M Newton, Woburn Sands

Was offered date and time to suit my requirement. Engineer turned up promptly on time and was courteous and friendly. Service carried out very efficiently. Any queries I had were answered without hesitation. Would certainly recommend Optima.

The Optima team were very hard working and professional. They were always polite and willing to make slight adjustments to meet our needs wherever possible. They left everything clean and tidy…I would highly recommend Optima and their workforce.

Mrs Mason, Milton Keynes

I have to say that our overall experience with Optima was above and beyond what I expected. The engineer that fitted our boiler did everything in his power to carry out our wishes. Every minute detail seen too. Thank you Optima for making it a positive experience. Would recommend to all.

From Andy who came to quote, to the two lads who installed my new boiler, I would have no hesitation in recommending Optima. They were all extremely courteous, and worked in a neat, tidy and professional manner. Very impressed.

Great experience with Optima. The service was professional, Tom – our engineer – was a delight and he took the time to explain how the system worked in detail before he left. Would definitely recommend Optima to anyone looking for a friendly and reliable gas engineer.
