“Great service from first phone call to completion of installation. Would highly recommend Heat NI for boiler installation. Installation engineer was there on time and left site clean and tidy on completion.”
“Recently had a new boiler installed and couldn't be happier with the result. The team were professional, punctual, and extremely tidy throughout the job. Everything was explained clearly, and the work was carried out to a very high standard. The boiler is working perfectly and the whole process was stress-free from start to finish. Highly recommend!”
