We had all our plumbing replaced by O'NEILL'S and what a brilliant job they did. From the girls in the office and lads on the road. Thank you so much you were a pleasure to deal with. Regards Carmel

Superb company to deal with. Kept up to date from start to finish. Short lead time for install, very friendly and clean installers. Top service for Gas Boiler replacements.

Genius Hub is reliable and user friendly. After sales service by Marc is excellent. Takes all worries away of buying this smart remote heating control.

We got a boiler upgrade and multi room controls system installed last week. Great system, very happy with it. The guys were very efficient and helpful. Highly recommend O'Neill plumbing & heating.

I have had my boiler serviced by many operators, good, bad, and indifferent. O Neill plumbing and heating have been the best I have ever dealt with so far. Punctual, tidy, no dramas, no fuss, and very generous with on site advice and knowledge. Recommend 200%

I found dealing with O’ Neill Plumbing & Heating very straightforward. Everything was carried out when they said it would be with our new Gas Boiler and they kept us informed at all times. I would recommend them to anyone.
Eric Herbert
I am very happy with the Oil boiler installed. From the very beginning very good advice, excellent work and after care. I would definitely recommend this company.
