About NIA-CON Limited
Expert heating, air conditioning and plumbing solutions for every space.
Company Background
The inception of Nia-Con Limited began in 2004 by Gareth Rankin; the name Nia-Con was taken from Gareth’s children, Niamh and Conor, and within a year of trading, Steve Bateman joined Gareth, so now the company offered both domestic and commercial plumbing and heating.
Five years on, Nia-Con Limited spread its wings even more when Paul Mawson joined the team, which extended Nia-Con Limited’s capabilities into the HVACR sector. Over the years, Nia-Con Limited grew with the young employees who were taken on board and put through an apprenticeship and became good engineers who supported the team.

We have always been extremely impressed with Nia-Con Limited and their team of skilled engineers, nothing is too much trouble, and they are always on hand should we need further advice / technical support. We’ve built a great working relationship over various projects and will continue to use Nia-Con Limited should we need additional systems. Their engineers are courteous, professional, and work to a high standard. We wouldn’t recommend anyone else.

Nia-Con Limited is a reputable company which has a longstanding relationship with our business. Over the years, they provided excellent service from start to finish. They always give good advice on the choice of air conditioning and do not trick customers into expensive installations. Each work project was carried out on time and without any delays. The engineers are friendly, professional and happy to answer any questions. Once the installation is finished, they leave everything clean and tidy. Highly recommended!
