Reliable and professional

Jamie McCartney and team did an excellent job installing a full new central heating system,(boiler,radiators, external flu, filter, pipework, electrics) at our family home. They were friendly and professional throughout. Jamie was completely reliable and consistent with cost, email communication and sticking to the schedule. He was most patient as I had a lot of questions. I also changed my mind a few times at the start too but Jamie was very flexible around change and I was instantly reassured at all times. The team are all very pleasant with nice manners. Jamie also sorted out a few extra niggles that cropped up too at no extra cost. The fittings done were to a high standard, very tidy, neat finish, which I love. They are hard workers, no messing around, very focused on the job and the time factor. I wouldn't hesitate to recommend this company and I was pleased with the costing too. Jamie has great product knowledge and knows his stuff well. I felt confident having them in our home. Thanks Jamie

Bathroom installation

Jamie recently completed a bathroom installation. The work was done to a very high professional standard and he has an eye for detail. He is very pleasant and easy to deal with. Communication was simple and he was punctual and reliable. He has a good relationship with a local supplier, which helped the job go smoothly. He also took good care to protect the rest of the house. I would definitely recommend him.

Boiler replacement and related matters.

Given my layman status, Mr McCartney broke everything down in his quotation. On appointment, he came when he said he would, dud what he said he would ( dealing with a few complexities along the way), explained what was to be done ongoing, and charged what he said he would charge. A tidy, professional job, with minimal disruption. Mr McCartney comes with my recommendation.

Brilliant New Boiler Installed - Highly Recommend

Jamie fitted a new Bosch boiler for us and did a brilliant job. He was clear in what he was doing, made it really simple and explained everything. Was very attentive to anything you said and any queries he was able to answer. Would highly recommend for anyone seeking to get a new boiler installed.

Boiler Replacement

We had our old combi boiler replaced with a Worcester Bosch combi and two new radiators fitted by J McCartney. Jamie provided a very competitive quotation and installation was done to a very professional standard on the date and to the price agreed. At every stage Jamie’s communication was first class and he could not have been more helpful. We have no hesitation in recommending J McCartney (Plumbing & Heating). Excellent service .

Great job, competitive price and great service

Jamie responded quickly to our request to quote for a boiler and system upgrade. The price was competitive with no hidden extras. Dates were set for the install and the guys rolled up at the appointed time, completing a little ahead of schedule. Budget was met. Everything was explained and questions answered in a straightforward manner. Jamie and his team were easy to have around, cleared up afterwards and left us feeling confident we were in safe hands. I'd highly recommend them and have already suggested to a family member that she make use of the McCartney team. Trusted traders indeed.

Very happy with the service Jamie provided. Needed a new boiler which involved a bit of problem solving and Jamie found a better more cost effective solution than I had been advised by anyone else.

Professional, Timely and Trustworthy

I contacted Jamie to install a new boiler for me after my old one packed in. He was professional in all aspects of the service, from sticking to the appointments he made with me, doing what he said he would do when he said he would do it, giving me a lot of confidence that things would go smoothly and in fact they did, which significantly reduced my anxiety levels! The boiler is fabulous, the new HIVE smart thermostat is wonderful and I could not be happier with the work done. I would definitely recommend this company to anyone.

Trustworthy & Highly Recommended

I used J McCartney (Plumbing & Heating Limited) to replace our old and inefficient boiler. Jamie was fantastic at talking us through available options and recommending correct size of boiler to suit our needs. He answered all our questions honestly and in full and even took time to explain the controls. Fitting was completed as agreed with minimal mess and disruption and all rubbish was taken away. A genuine business I would have no hesitation in recommending to others.

Professional, Timely and Excellent Service

I used J McCartney (Plumbing & Heating Limited) to install a top of the range boiler and a new radiator for our kitchen which was being redone. Jamie was very efficient. He turned up on time and worked quickly and efficiently and explained throughout the progress he was making. Jamie also put new valves on our older radiators throughout the house which were broken. A year later we have had no issues with the boiler or radiators and we intend to use Jamie in the future. He came highly recommended through word of mouth and lived up to all our expectations.

Bathroom revamp

Jamie had previously fitted a boiler system for me, so I know the standard of his workmanship. I asked him to totally strip back and revamp my upstairs bathroom/shower room. I ordered all materials (with Jamie's recommended suppliers) and he provided all the services, plumbing, tiling, joinery, electrical work and most importantly all waste collection. The results are fantastic and the workmanship is of a high standard. I would have no hesitaion in recommending J.McCartney as a supplier.

Quality job

I have no hesitation in recommending this company, from estimate to completion this job was handled efficiently and pleasantly at all times. I might add that my wife and I have high standards and at no time during this work were we concerned. We would safely recommend Jamie and his team to anyone and will use them in any future work.

New full central heating installation

I used this company for a recent new full central heating installation in a large top floor flat. From the initial quote to commissioning the system, Jamie and his team were professional, punctual, hard working and efficient. Communication was excellent, and the job was completed in 3 days. Jamie returned a few days later to check everything was in order and to sign off the system. I'm delighted with the job, and have no hesitation in recommending Jamie and his Company. I will certainly use them for any future plumbing or heating requirements.

Jamie is not only trustworthy and reliable, but a lifesaver

We were very unfortunate with the purchase of our first home. Upon receiving the keys we noticed straight away that the boiler was located behind kitchen units and a splashback (which was a health and safety nightmare never mind a practical one). We must have had over 15 gas engineers out to inspect the property but Jamie is the only person who we trusted because he listened to our concerns/ needs, explained everything to us in simple terms and advised us of our options rather than telling us what he wanted to do. Jamie was true to his word and provided a quote and his availability within a matter of hours (knowing we needed the job completing ASAP to allow us to move into our new home). Jamie visited our second floor flat in busy street on three occasions. First occasion to remove the old boiler in order to allow the joiner to prepare the space. Second occasion to install the boiler and drill a new flue hole (new boiler was in a new location). Third occasion to check the boiler was working and complete a chemical flush. On all occasions Jamie was very professional, he removed any rubbish (including the old boiler) and left the place clean and tidy. Jamie respected our home, listened to and answered our concerns and helped us in our time of need and for that we are grateful. We are looking forward to moving into our new home and will 100% be using his services on a yearly basis to service the boiler and any other plumbing jobs we require. We would 100% recommend Jamie.

Professional and Reliable

Jamie has now installed 2 boilers and a mixer shower at 2 rental properties. In every aspect of his work Jamie is calm, efficient and highly professional. He attended the properties, called to offer his advice and provided written detailed quotes promptly, giving dates when he could carry out the work. He arrived as arranged and carried out each job for the price quoted. When one of the old boilers broke down he even offered to provide electric heaters to the Tenant until the new boiler could be fitted - much appreciated. After the installation, all necessary documentation for guarantees and Landlords Certificates were forwarded to me. I would not hesitate to recommend Jamie to anyone.

Excellent service, good value and very professional. Highly recommended.

I inherited an old boiler when I bought my home, it was never quite right but Jamie did a great job servicing it and keeping it going. This year it finally gave up and I had no hesitation in asking Jamie to see if it could be fixed and, if not, quote for a replacement. He responded quickly to my email, arrived when he said he would, checked out the old boiler and, as it wasn't economical to fix, booked in a date to install a replacement. He provided some advice on the options and a couple of quotes. I checked out the options myself and discussed with a friend down south who had a new boiler recently, we concluded Jamie had recommended the right option for me and the quotes were very reasonable and professionally presented. Jamie completed the installation quickly and efficiently, he took all the rubbish away and left the work area tidy, provided comprehensive paperwork and answered all the questions I had. It was the middle of lockdown and I was completely reassured by his attention to safety and respect for me and my home. He returned a couple of weeks later as planned, to check the filter and flush the heating system, again he arrived on time and completed the job quickly and efficiently. I am delighted to recommend Jamie as a trustworthy, reliable and professional tradesman.

Did exactly what he said he'd do, when he said he'd do it, at the price quoted.

Jamie and his assistant Andrew replaced my central heating system entirely, and I'm entirely satisfied with their work.

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.

Check the WaterSafe register
Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
