Who We Are

Allgas Heating, Bathrooms and Plumbing is the leading bathroom, heating and plumbing contractor in Dublin. With almost 30 years’ experience in the business, we are experts in what we do. Our mission is to meet all our customers’ bathroom, heating, plumbing, home maintenance and improvement needs with professionalism, quality and courtesy. We pride ourselves on the level of service we provide. Our before, during and after work service is unrivalled.

The Company was created in 1987 by two experienced and qualified Dublin Gas technical experts, Thomas Mahady and Bernard Leech. We have since then built up our quality gas installation, repair and maintenance, oil boiler installation as well as bathroom and plumbing business throughout the Greater Dublin area.

We now have a team of 5 fully qualified RGII installers. We have over 4,000 satisfied customers. The reason our business has grown is the number of repeat customers and referrals from satisfied customers.


  • This field is for validation purposes and should be left unchanged.

Personal service to our customers is very important to us. We are a company that is large enough to provide excellence and reliability but small enough to build personal relationships with each and every one of our customers.

Meet The Team

Once a customer always a customer

We are well aware that our customers are our business and we value each and every customer. This is the ethos of our company and is reflected by our staff in our dealings with each customer. Customer feedback is strongly encouraged and shared with all our team. We would hope that once we carry out a job for you e.g. service your boiler, we would be your first port of call whether to fix a leaky tap, get your attic insulated or convert a bedroom into a bathroom. Indeed many of our customers have been with us since we started in 1987. We regularly do work for the now grown up children of our older customers.

No job too small or too big

From a kitchen tap to a complete refurbishment of a house, no job is too big or too small. We in Allgas Heating, Bathrooms & Plumbing pride ourselves on treating each job and each customer as our priority whether we are just carrying out a boiler service, installing an attic tank or completely revamping the heating, bathroom or kitchen in your home.


If I was to sum up Allgas it would be “friendliness and professionalism”. They originally put in my gas central heating in my first house 12 years ago and came every year since to service it. They have since done the same job in my new house and refurbished my bathroom there. I wouldn’t use anyone else.
