"Gerry Quigley was very helpful and reliable. He did remedial work on a previous boiler installation by another installer (effectively re-installing the boiler). Gerry worked very hard to complete the work and is clearly very knowledgeable and confident in his abilities re : doing a good job. The job was carried out to a high standard overall, and Gerry takes pride in "getting it right". He completed everything he said he would do, and communicated effectively from the start to finish of the job. No concerns. Delighted and I would very happily recommend."
