The guys from Superefficient were prompt with their appointments for estimate and actual fitting. Answered all my questions satisfactorily. George who fitted was timely, professional and tidy vacuuming after he had finished. Job well done. No extra hidden costs and bang on estimate.

A special thank you to Jack for amazing efficient service, We have an emergency "same day" plumbing contract with another company and they could not send us anyone round for four days. I rang Jack at 11 am today as we had a leaking toilet- he said someone would be round between 2 and 4 pm An engineer called 5 minutes past 2 and fixed our leak efficiently and quickly. Thanks for great service- we will definitely use you again

Unable to make it to meet Superefficient LTD at my parent's house, I had to rely on Superefficient LTD to help. Jack turned up promptly without much notice, quoted, and then fixed my parent's boiler efficiently, without any bother to my parents, and was very pleasant and professional too. He kept in contact with me all the way through, making sure me and my parent felt assured. Thank you Jack. We'll see you again at some point I'm sure.

Superefficient Limited are a good find. If you are considering using them - I would highly recommend the service they provide. We have used them three times now and they never let us down. Our boiler repair and service and the rest of the plumbing work they carried out in our flat was done in a highly professional manner. They tick all the boxes: they are knowledgeable, professional, keep to agreed schedules, are friendly and cost-effective. They are now my first point of call for any gas-related or plumbing work.

At a weekend my boiler broke down and was judged to be condemned. I chose 3 trusted traders and also used the relevant Which? report to choose a Vaillant boiler as my replacement. Vaillant website allowed me to choose 3 of their endorsed fitters. By tuesday morning I had all estimates and subsequently chose SuperEfficient Ltd who provided one of the lower quotes. More importantly, perhaps in consideration that my wife and I are senior citizens, was their commitment to do the installation 2 days later on the thursday and to rearrange their other commitments to accommodate our urgent needs. I think they managed this by hiring additional professional expert help. The job was fully completed in very reasonable time with no fuss or time breaks and all rubbish removed leaving a clean home and garden. That evening we truly enjoyed and appreciated good warmth and comfort. SuperEfficient you were pleasant, amenable, super and efficient and I have no hesitation in recommending you.

Highly recommended
Laine attended to fit a new water heater only to discover it was the wrong unit. He went & changed it and then what proved a challenging job. Laine rose to the occasion without any complaints. He was polite & friendly and above all a clean and tidy contractor. We were recommended to this company and can understand why , Super Efficient by name and super efficient by nature. So impressed they are now enrolled on our books as one of our contractors.

I called Jack a second time, to install a boiler in one of my refurbishment flats and to replace a section of lead pipe serving 4 flats in my building. I was apprehensive about cutting the supply to my neighbours, in case the work took longer than expected. I needn't have worried. Jack and his time arrived promptly, with a new boiler and all ancilliary parts. They replaced the lead pipe without fuss or complaint from my neighbours. They replaced the boiler and the pipework was truly the neatest I have ever seen. Once again, Jack came through for me and did exactly what we had agreed, to a very high standard and at the price agreed - no surprises! I will use Jack again.

My boiler broke down in the run up to christmas, leaving my family without heat or hot water. I found Jack on this website and was impressed with his reviews, so decided to give him a call. Jack was very professional, really knew his business and gave me the reassurance that he resolve my problem and restore service. He arrived at the arranged time, with a new boiler and all ancilliary parts. He and his team replaced the boiler and got the system going quickly. A few months later, the boiler failed. Jack came around promptly, diagnosed a PCB problem and scheduled a Vaillant engineer to visit. The engineer refused to work because the boiler was installed above their safe working height (it was 6 feet off the ground). Jack arranged a second visit from Vaillant and arranged for a couple of his guys to attend to deal with any issues. The PCB was swapped over and full service restored. I could not ask for a more dedicated professional and will use him in future.
