Client Reviews

  • We have been a customer of HES for many years and more recently have become a drop off and collection centre for the calibration of test equipment.

    One of the biggest problems for service engineers was the length of time it took to have their testing equipment calibrated and returned and a waiting time of 4/6 weeks was the norm. HES aim to have this completed in 3 to 5 working days which is of enormous benefit to our customers. HES also provide an excellent service for all engineers instruments and supply a good range of tools/consumables and we strongly recommend them to all potential customers.

  • The main reason for doing business with HES is that they stock a range of high quality essential equipment like Anton Combustion Analysers, Extec Multimeters and Extec Digital Manometers etc. The addition of a small tools and consumables service has helped in stocking the essential day to day bits required to complete installations.

    HES do business in a very personal way and are local and available to cater for questions, enquiries and technical back up. The local recalibration service and loaning of instruments if necessary reflects their understanding of what active Installers and Service Engineers require in support to their day to day business.

    I would recommend HES to any person active in the Heating and Plumbing Industry without hesitation.

  • From our extensive Installer Training Courses here at Grant Engineering Ireland, Charlie O’Neill and his Heating Supplies Company has achieved an excellent reputation for his equipment and after sales service with the attendees.

    In an age where value for money and reliability are now a prerequisite, HES has delivered both consistently now for many years.


  • As the technical, safety and Quality Manager in Bord Gáis Energy for many years dealing specifically with Appliance Service Engineers, we have availed of the excellent service from HES.

    All 70 engineers purchased the Anton Flue gas analyser and various safety equipment from HES with the backup of quality service and calibration facilities in Ireland. HES has become a one stop shop for the heating engineers with all the equipment and tools required available within a short space of time. I was delighted to see the range of tools and accessories extended over the last 12 months. Keep up the good work

  • Charlie O’Neill from Heating Engineers Supplies has being coming to METAC Training for the past 10 years firstly representing CSL while supplying Anton Analysers and following that when he took the plunge and went out on his own with much support from both CSL and all the clients including METAC training.

    Charlie has built up a badly needed service to both ourselves and our clients in supplying most of the equipment and materials we all need for testing and insuring all the work we carry out, and our candidates is both safe and to a professional manner.
