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 as a plumber. John progressed through the ranks and won employee of the year at British Gas, he went onto become a Technician, and became a trainer and was well known within the company at fault finding the more complex heating issues.

After gaining enough experience John looked to expand his knowledge and skills by creating his own thriving business and has not looked back. We have built a loyal client base over the years and look forward to this continuing for many years to come.

John is married to Abbie, and they have two children, a son and daughter.

In his spare time, he spends most of his time catching up with paperwork! 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, organising 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, prior to this she was a Branch manager at the Travel Agent- Lunn Poly, now Tui, and then a lettings manager at an award winning local Letting Agency.

She currently works part time in the accounts department at a local secondary school and when not doing either of her jobs, she is busy ferrying their two children to the many after school commitments they have. 

Her hobbies include chilling out with a glass of wine & a good book and catching up with her box sets whilst doing the ironing!

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!
