A quick note to say how much we appreciate the professionalism, hard work, kindness and consideration shown by Chris, Tam, Zander and Jake. They really are quite excellent and are a great credit to your company.

We recently had a gas leak in our property and the engineer Bob was very helpful went over and above to get the problem sorted for us, coming back a second day to resolve the issue. Will defiantly recommend to family and friends.

I would like to thank you for the prompt and professional service I received from your company last week when my boiler decided water would be better flowing throughout the house than the pipes. Your engineer was on site and the parts were replaced before you could say 'what the hell did I do to deserve this?
Now that I know you can offer such a professional and speedy service, I will have no difficulty in recommending your company in future. Thank you for your assistance.

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.

Friendly, efficient service fitting our new boiler. Really pleased with work and the boiler has made a massive difference to our heating and hot water - no problems with either now. Would recommend these guys.

I would like to send my appreciation and thanks to Jim Robertson after his successful repair work on Friday 3 March 2019. Over the last year and more frequently, the last few months our boiler stopped providing heat to both radiators and hot water taps. Several visits by different engineers did not solve the problem, most probably because, at times the boiler started working of its own accord before an engineer arrived. So far, everything is working.

Thank you very much for the prompt response and repair of faulty RF Thermostat under warranty. Excellent service again! It is much appreciated. The after care is just as good as the original installation and just as important.

We wish to commend your service engineer JIM who called to repair our heating system today. He was efficient informative and polite. Most importantly he fixed the problem. We will have no hesitation in recommending your services to family and friends based on today's work. Thank you Jim. *

JOHN ATTENDED MY HOUSE TODAY AND HE WAS VERY HELPFUL AND DID A GREAT JOB. JOHN TIDIED UP BEHIND HIMSELF AND HE WAS VERY RESPECTFUL TO ME, I WOULD HAVE NO HESITATION IN RECOMMENDING YOUR COMPANY TO ANYONE AND WILL PASS ON YOUR DETAILS TO FRIENDS AND FAMILY

Just a quick note to say how much we appreciate the professionalism, hard work, kindness and consideration shown by your installation team (the three engineers and the Electrician (names who we did not get) who visited our home to install a new boiler. We cannot forget Colin Robertson who visited our home on many occasions to get things moving.

This morning an engineer called at our home to check the filter which was really dirty and he cleaned this, this going that extra mile. Thanks to all we really appreciated this.

Your Team really are quite excellent and are a great credit to your 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. Regards Raymond Berry

Donnelly's have just installed a clos-o-mat toilet in my gran's house. She was very pleased with how efficient and friendly the plumber and electrician were and was happy with the service.

We picked Donnelly & Co to convert our ensuite shower room into a wet room. I am disabled and needed extra space so allow me to wash. We found that not only was the quality of workmanship excellent, the sales person Patrick showed care and understanding for the problems I was having. With his experience we were able to pick the correct fittings and finishings, which has given us not only a very functioning shower room, but one that we are delighted with. Thanks Guys

Boiler repair was carried out quickly and the engineer was polite and helpful. Would highly recommend the company.

Had a combi boiler with nest fitted,excellent job would highly recommend. I had been dreading it as i had an old tank to be removed , they were reliable turned up when said unlike alot of tradesmen these days, were tidy, polite and done the job in a day, definately give them a call if considering any plumbing and heating jobs

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.

Had an issue with my boiler that left me and my family with no hot water or heating however WM Donnelly could not have done anymore.

The communication was spot on, the engineers that attended where fully professional and friendly. They kept us well informed with what the issues were, how they would be resolved as well as potential cost involved.

Finally the girls in the office were great and didn't get sick of my calling for updates. Special mention to Jess who managed to support me through the process including speaking to my insurance company. Couldn't have asked for any more any you was all great to deal with.

Sorry I never got the Easter Egg to you Jess. Once again Thank You for what you did.

I’d like to pass on my thanks for a great installation done by Colin Cochrane– he was great at his work.

Very pleased with new Nest installation. Experienced engineer who explained and installed the device. Great for controlling heating when your not at home.

I just wanted to give some feedback on my experience. I had a failed install last week (no fault of yours) and required a new install. The service received was excellent. From calling you at 10:10 this morning, the engineer called me back and was in the property by 10:45, The install had been completed successfully by 11:15 and everything was in working order. This level of service was way above my expectations and I just wanted to take the time to share this with you. The installer (John) was really helpful and is a credit to your company.

Jim Robertson was excellent in dealing with my repair. He found the fault very quickly and had the spare part in his van. Jim is welcome in our house any time.

Fantastic service even though they had to switch our services of...brrr but was for safety reasons as we had a leak. Turned up with the wrong part but it was an easy mistake to make so our engineer (Jim) pulled out all the stops to make sure we had our heating back on that day rather than have us going without heat any longer..Had to use them last year too and recieved an excellent service then too. Feel really confident with them. Staff are all really professional, friendly and could not be more helpful. 5 stars

David has done an amazing job on the boiler install, he was very efficient and made sure everything was cleaned up after him 🙂

Had a Worcerster Bosch 30cdi with the Worcerster wave and filter fitted on Monday. What a difference to the old 10 year combi I had previously. Guys finished in one day and done dusted. The estimator Colin was great.

Great service. Good job well done

I cannot recommend this company highly enough. I had a Tado installation carried out by one of their engineers who was reliable,punctual,efficient & tidy! (Which was a big bonus for me!). My heating bills have greatly been reduced since my installation.

Professional service from start to finish, great staff and would totally recommend to anyone 🙂

Great customer service, engineers are quick and thorough. Very punctual, clean and tidy. Always reliable and very easy to communicate with. I've recommended them to many friends and family too.

I recently had a bathroom fitted by Donnelly's and I was very impressed with the work. The workmen were very professional and courteous, left a great job and tidied up after themselves too. Office staff I spoke to also were very helpful. Delighted with the overall job and experience.

My recent installation went very smoothly. Wasn't sure about about the process and the guys at Donnellys took the time to explain everything to me which put my mind at ease. The engineer was punctual and proffesional and the communication was excellent throughout.

I just wanted to say a big thanks to Michael Kyle for carrying out my gas boiler safety check. I thought this was going to be a waste of time as the previous engineer from another company had fixed flue that was not safe due to external works. Michael discovered again that my flue was unsafe after external work had been completed. He quickly disconnected my boiler due to safety risk. Michael was very professional, helpful and informative.

I recently had Colin Cochrane out at my property to fix my boiler, his service was great. He went above and beyond to find the problem with my boiler staying until 9pm that night and returning the following morning when most engineers would have gave up. He managed to find the fault and now my boiler is fixed.

We recently had a gas leak in our property and the engineer Bob was very helpful went over and above to get the problem sorted for us, coming back a second day to resolve the issue. Will defiantly recommend to family and friends.
