Here are just a few recent reviews from our customers, you're in safe hands with us. Please see our Website for more excellent reviews.
We had a new combi boiler fitted through Corgi Home Serve and the job was given to Donnelly’s. On arrival to fit the new boiler it was discovered that the rep from CorgI recommended a model which was far too big for the cupboard in which it was to be fitted. John and Iikidiusz from Donnelly’s were absolutely amazing. They managed to source a boiler which not only fitted perfectly but was more efficient. They traveled all the way to Ayr to collect it and even provided us with heaters because they obviously could not finish the job in one day due to Corgi’s mistake. I am a pensioner and have had some bad experiences in the past with certain tradesmen but both John and Iikidiusz were absolutely amazing. I would have absolutely no problem with recommending Donnelly’s to anyone who is looking for a decent, honest and reliable service from such a fantastic company.

Excellent from start to finish, girls in the office customer service brilliant (so polite, happy and friendly), engineer Ken fantastic couldn't do enough for us to get our heating back up and running. Forget the Big Companies for Gas maintenance/Service. Support local business who really care. When my contract for annual service/maintenance is due next year I'll e contacting William Donnelly & Co. Thanks to Paul for taking the time this morning.

On the 18th February I had some work done by your company and I would like to congratulate you on the very high standard of your staff. From the initial survey carried out by Colin Robertson to the team who carried out the work, Billy, David & Ross, they were all first class. They were pleasant, mannerly, tidy and did a really competent job very efficiently and quickly. I was most impressed and I think they are a credit to your company and its reputation. I will not hesitate to recommend your company to everyone.

Installing a new boiler usually takes anything from 1-3 days. The length of time varies depending on a few different factors:
Is your new boiler the same type as your old boiler? If so, this will make installation more straightforward. If your old boiler was a combi, for example, it’s simpler and quicker to replace it with a new combi. Changing to a different type of boiler involves extra work for the engineer.
Is your new boiler in the same place as your old boiler? Again, this will make installation simpler and quicker. Relocating a boiler creates extra work, such as changing the pipework.
We have over 100 different models within our range, all produced by leading manufacturers like Worcester Bosch and Vaillant. Our boilers are selected to work with different sizes and types of properties, and all are chosen for quality, reliability and performance.
The cost of a new boiler depends on a number of factors. Prices generally start from £1,500 however some models offer more premium and advanced features, while others are designed specifically for customers who are working to a tighter budget. For every boiler type and size, we aim to offer as broad a range of price points as possible, so that everyone can find the right boiler for their home and their budget.
Yes, we are still installing boilers. But we’ve updated our procedures to keep our installers and customers safe.
