‘A breath of fresh air’

It’s been a pleasure dealing with Mel in the time I have known her, ‘A breath of fresh air’ is what my team and I comment on Mel, she is young, energetic, she has an eagerness to develop markets and the customer base, as well as the biggest passion for boilers and renewable energy I have ever seen!!! Mel stands out where she knows the ins and outs of all other manufactures boilers, what technology works with what and more importantly the common sense that should be prevailed in designing heating and renewable energy systems. I have worked very closely with Strata homes in Doncaster for some years now and introduced Alpha boilers as a Code for Sustainable Homes Solution to their developments. Mel has continued to give them the service they require, and develop that business to ensure they procure 100% of Alpha boilers; working very closely with Ian Corner who I know has an excellent relationship with Mel, and I must comment he regards her very highly for the service she provides. There is not a bad word to be said.

‘Exceeding expectations and going the extra mile’

I have had the pleasure of working with Mel on numerous projects over recent years and I have always been impressed with her positive attitude, openness and technical expertise. Mel has always been a complete professional and has consistently delivered when required, often exceeding expectations and going the extra mile. It is clear that Mel is a hard working individual, who is driven and will succeed in everything she does. It has been joy working together and I hope to continue to do so for many years to come.

Very professional and knowledgeable. Offering excellent service to clients.

Our company worked closely with MJL for approximately 18 months until our business was transferred at the end of last year. Melissa took care of all of our design work and also offered technical support and advice to our clients across the UK. She is very professional and knowledgeable. Offering excellent service to clients with design and product experience across a number of technologies and market sectors. She is able to work to tight deadlines and is always prepared to do whatever is necessary to keep clients happy and ensure excellent retention of business for her customers.
