Who are we?


John McEneaney- The Technical One!
A very experienced gas engineer who started life out as a trainee plumber with Richmond College, who, after passing his Plumbing NVQ Qualifications decided he wanted to learn more about the heating and gas side of the industry.

John embarked on an Apprenticeship with British Gas and became a qualified Gas Engineer as well. John progressed through the ranks and became a Technician, and is a well known expert at problem solving the more complex heating issues, After 7 years, John decided the time was right to start his own business.

John is married to Abbie, and they have a son, Thomas, & a dog called Duke, who keeps them very busy when not at work.

In his spare time, he spends most of his time catching up with paperwork!, and seeing friends and family, and loves cheesy horror movies and a good old takeaway.


Abbie McEneaney- The part timer of the company!
Abbie is in the office part time, manning the landline, doing the accounts, booking appointments, and dealing with any marketing that needs to be done.

Her background in Sales and Customer Service certainly helps her do this, with 9 years at Travel Agent-Lunn Poly, and 5 years at a leading local Letting Agency, as Lettings Manager. She now works part time in a local Letting Agency, and when not doing either of her jobs, she is busy entertaining their son Thomas, and thinks she has a far harder job than John.!

Her hobbies include chilling out with a glass of wine & a good book and catching up with her Sky Plus Box!

The Aim:
Our aim is simple, to make sure all our Landlords, Tenant’s and Private Clients get the best possible service. That we are friendly and down to earth, competitively priced against our competitors, but most of all, that every client we deal with, is always given the correct advice, and every job is done the way we would want it carried out in our own home. That all safety aspects are covered and our clients can have the peace of mind that they can actually rely on their Gas Engineer!
