After a panic when my boiler broke down on the coldest day of the winter so far. I rang Alex for help,the service he provided was first class. I am very impressed with his reliability and professionalism. I felt humbled in the manner of how he went out of his way to sort out our problem with our boiler,replacing it the day after I reported the fault.His workmanship was brilliant and i would very strongly recommend him to any one I know.



Yes, very efficient service is provided. Highly recommend



Honest, trustworthy, absolutely spot on. Fantastic service and great workmanship. Only company we will now trust to do any work for us. Prior to recent work Alex has been to us in the past and sorted the plumbing out where other plumbers from our insurance cover have failed, the same has happened on this occasion. Have now stopped paying our usual boiler insurance and have taken out Ambien's cover.



Ambien Heating Specialists are a company to be trusted for price and service – I would wholeheartedly recommend them to anyone. Alex visited my Retford-based house to assess which boiler best suited my needs and quoted a price that I was happy with. He and his team made the installation of my new Ideal combi-boiler (complete with new copper pipes) straightforward with minimal disturbance and did a quick but thorough job. He and the lads who work for him are knowledgeable, supremely helpful and hard-working. I was extremely satisfied. I rarely give a business a five star review but Ambien Heating Specialists more than deserve their perfect rating.



Called Alex for assistance due to heating failure yesterday. Returned the call and attended to fix the problem, very professional and a very friendly attitude, heating now working, less than 24hrs after requesting assistance, brilliant service, HIGHLY recommended, many thanks



Was having trouble with my boiler. Alex went that extra mile to identify the problem and after several visits and sheer dedication to his work he mended my boiler. I can't thank him enough for his hard work he is truly committed to his business and providing a fantastic service. I would highly recommend him.

Had a hot water heater leak had to turn the mains off alex was very helpful in providing over the phone assistance then quick to arrive to resolve the problem very nice guy hard working

Having recently moved into a new house, I found the hot water pressure to be very low which had a major impact on the shower. I explained the problem to Alex and he suggested changing the water heating system to an unvented cylinder. Alex provided me with a very competitive quote and carried out the work a couple of days later. Alex was able to complete the work in a day and we now have mains pressure hot water with the shower a million times better than it was! I would strongly recommend Alex for any heating / plumbing issue you may have. He is friendly and hardworking, which is probably why he is so busy!

Ambien Heating were professional in not only over the phone when the boiler was playing up; but also efficient in coming out - fixing the problem and servicing the boiler at a very reasonable price! Very responsive, efficient, professional and reliable service. Thank you.

At last, a plumber who COULD be bothered!

I booked a call with alex on Sunday for pm the following day. The man came at the specified time and did a great job. First Class Service, and local too. I will use Ambien again.

Thanks all round!! Happy Christmas.

Very happy with the new boiler installed today by Ambien. They turned up on time, worked hard all day without a break and everything was cleaned up and controls explained before they left. We have such confidence in Alex's knowledge of his trade that we have taken out the very reasonably priced care package he offers. We have also asked him to quote to replace our bathrooms. Alex and Blaine were very easy to have around despite having to work round our very excited dog. Just make sure you get in some chocolate bourbon biscuits!!

Because of no hot water due to boiler problem, the insurance company gave us Ambien's details so this was the first time that we had used them. It wasn't a straight forward job as initially thought, but Alex dealt with the inurance company throughout and explained everything to us clearly. The job was done professionally and we will use Ambien in the future the maintain the boiler. I would highly recommend Ambien.

Ambien swapped my nasty old boiler for a new gas one and installed some new rad's too as there were some cold spots in the house. They obviously knew the technical stuff very well and explained the options of different types of boilers and tanks etc clearly and we are really pleased with the results. The job was done very quickly and efficiently and kept clean too. I'd not hessitate to use this firm again.

My boiler broke down for a second time and I knew that I would have a new replacement. Whilst getting quotes I rang several companies in Lincoln plus Alex in Gainsborough - he was the only person to get back to me (as well as British Gas of course!). Whilst trying to juggle around a new arrival to his family, he kept contact and made the effort to out as he could (at the weekend). He sent me a good quote and soon after my installation was booked in. Alex and his colleague arrived early and immediately carried out the relevant tests and ensured relevant protection of the carpets etc. The guys got on with the job in hand effectively and efficiently and both were cheery and easy to get on with. They completed the job to a high standard and I am extremely happy with the results. The service was professional, Alex was honest and experienced in what he was explaining. 

I would definitely use Ambien again and highly recommend them.

We used Ambien to replace our central heating boiler and two radiators. Alex took two days 2 and 3 June 2015 to do the work. The work was carried out in a friendly, professional, courteous and professional manner. 

This was the second time we used Alex and i would certainly use Alex and his company in future. 

I would recommend Ambien.

Thank you Alex and Roy (his assistant).

Alex came to us recommended and what a recommendation. He did a great job replacing our boiler, they were very tidy and went the extra mile to please. Nothing was too much. Alex I will be recommending you to anyone who requires a plumber.

Had Alex out to give our oil boiler a yearly service and to fit a Watchman sonic onto the tank. He had been out to us before to fix our boiler and was very competent, honest, knowledgeable and good value for money. Did both jobs on this recent occasion in no time at all and charged a reasonable fee. He also suggests anything that might need doing in the future to improve efficiency, but does not push you to have the work done. 

He comes across as very friendly and honest and we would not hesitate to use him again. Like a breath of fresh air after dealing with dishonest Plumbers/Engineers in our time. Thanks Alex.

Alex offered excellent, timely, genuine and friendly advice after our hot water tank leaked due to corrosion. Alex completed the installation of a replacement tank and associated piping as soon as he was able to do so at a very competitive price. The work was completed to a high standard, and I would definitely recommend Alex to other people in the future.

Very efficient - reasonable prices and very capable. Recommended....

This is the second time Alex has visited my house. I have an emergency call out policy with my insurance company, THANKFULLY. My shower was only pumping through cold water, which isn't an emergency however, this shower is used for me to shower my severely disabled daughter. Alex called the insurance company (who wouldn't normally class this as an emergency) and managed to arrange for a new shower to be installed...from initial phone call to insurance company to shower being installed and fully working. 24 hours!!! Fantastic
