“A very happy ZARA HEATING customer. Having been messed around by local plumbers who played the usual guessing game with our old boiler and cost us money by replacing bits that didn't need replacing, I went in search of a new boiler. After my experience with the above, I went to ZARA HEATING with a certain amount of apprehension, not knowing what to expect. I can only say this: Craig, the ZARA HEATING installer who did the job, was absolutely top notch. On time, put down dust sheets everywhere(without being asked), worked solidly throughout the day and finished everything on time and done properly. No mess, no fuss, absolutely first class job. Cannot recommend him highly enough. The ZARA HEATING contracted scaffolders (necessary for a 3 storey house to replace the roof flue) turned up dead on time, did a quick and efficient job and were gone promptly the job was finished. So far as ZARA HEATING, the company, well, all I can say is, it's brilliant. The price was extraordinarily good, the communication before the installation first class, thanks to Scott and others in sales and customer service, and the whole thing went off very, very well. We're very pleased with every aspect of this job and it's good to know that there are companies out there that do actually appreciate their customers. Very well done ZARA HEATING!”

“Very helpful and patient with all our niggling problems. Great attention to detail and took the time to explain how it all worked. Will certainly recommend Alp to friends and family.”

“After having Louis visit us a couple of times to discuss our requirement we were impressed with his professionalism and work ethic so asked him to take on our job. He arrived on 18th October with his team and completed the work, to our total satisfaction, in a day. Everything was left clean and tidy and our old boiler, together with all other waste, was promptly collected the following day. We cannot fault Louis and his team and their total commitment to ensure we were satisfied with the work. We would highly recommend them and will use them again.”

“Shahid was nothing but professional and reliable from day one. Having to arrange for a boiler to be fixed whilst living abroad, and having no hot water or heating for a tenant during winter was particularly stressful. Shahid took control and identified and remedied the problem quickly and efficiently, which really set my mind at ease. I won’t hesitate to call him in the future should we need plumbing help.”

“I am very happy with your work! Always continue on providing quality service and always satisfying your customers. You really are the best service provider in this area!”

“We had a plumbing emergency, pipe burst, water everywhere. Called, sorted for us immediately, came next day with the parts to finish the job, quickly and efficiently. they are charming and a pleasure, so pleased we contacted this service.”

“I contacted to Niaz for a Landlord’s Gas Certificate. He arrived promptly, and completed the inspection. He had with him and fitted a carbon monoxide alarm. Thank you.”

“I called Zahid, he was just so helpful from beginning to end. He came out the same day, repaired my elderly mothers boiler so that she didnt get cold. He showed such compassion and care. He explained everything clearly....Zahid was very knowledgeable. I have cover with British Gas, but im going to cancel now i have found Zahid. British Gas never come to do a repair the same day. What a fantastic service !! Thank you Zahid”

“​These guys are knowledgeable, kind, and patient. The quality of their work is exceptionally high, but perhaps most importantly, they are genuinely great people, the type of people that you want to be your friends or neighbours. What a gem of a company. I would highly recommend Yassin and his team!”

“Boiler stopped working and had no hot water or radiator. George was really great at diagnosing the issue even before going to the property. Very responsive to the call, video chatted on Whatsapp to show him the boiler and he gave great advice on what to do. Extremely knowledgeable and I would recommend.”

“Great service and good value. Ian arrived promptly and carried out our Landlord Gas Safety Inspection in a comprehensive and professional manner. He helpfully explained what he was doing throughout the Inspection and topped up our boiler pressure which he noticed was running low.”

“I am very happy with the service I received from the team at DJL. They came in within the hour to 'save me' get a kitchen water leak stopped and enabled me with a permanent fix at the next convenient time. Their focus was on a long term resolution and provided sound advice along the way. Would recommend them to anyone.”

“I recently used Action Services Plumbing for first time for a rental, based on internet reviews and responsive to phone calls. First appointment was missed/not informed so not a great start, but I called again and 2nd time was on time,, fixed quickly and efficiently and reasonably priced. Always very responsive to phone calls, invoicing quick and easy via phone. Will definitely use again and recommend.”

“Really loved using A1 heating and plumbing for my issues. My radiator burst a leak and A1 came out within a minutes notice, stopped the leak and isolated the radiator, provided a quote for a new radiator and gave me a date of their earliest availability. They had also noticed that I required a new TRV on my other radiator whilst balancing the system and that was a nice quick easy change, will be painting it soon! The engineer was friendly, factual and abided by the covid-19 regulations. The pricing was very adequate as I looked around and found A1 to be the most reasonable given the timeframe of the leak! Will be using them in case anything else happens!”

“I had the pleasure to work with Sam and Lloyd on many projects over the years. I can honestly say they are the best people I ever had the pleasure to deal with. Since the first time I spoke to Sam, he put my mind at ease straight away, showing knowledge and already giving me an idea of the possible causes to the plumbing issue I had. Lloyd knows his stuff about plumbing and heating and he’s one of the few people left in London who can get your Aga or Rayburn up and running again. Is rare to find professionals with such knowledge and understating of your system and appliances and I will definitely not hesitate to recommend this company to anyone who needs plumbing, heating or any general building work carried out. If 6 stars was an option, they definitely deserve it.”

“Amazing customer support from Elin and Mark . Went the extra mile to help resolve a problem with my boiler .”

“We had our bathroom completely redone and are very pleased with the results! Our fitter Craig, is worth his weight in gold - hard working and great at what he does. Overall, I would recommend NLHP - good communication while the project was happening, high spec workmanship and a very knowledgeable team!”

“Very professional company from the first call to completion of the job, Calvin reacted to our immediate problem with calmness, knowledge, speed and an understanding to our predicament that is rarely seen in companies now a days. I will certainly recommend Heat Solution London and Calvin to everyone. Well done guys! and thank you for your excellent professional work.”

“I cannot commend this company highly enough. They were professional, friendly and very knowledgeable. The work was done quickly and to a high standard within the agreed time scales and at the quoted price. I work with a number of different contractors in my line of work and I can say that this company was the best I have used, either professionally or personally.”
