Gas Wiz is probably the remaining honest and efficient company in the Plumbing business in London. I had a problem with my boiler and everything that was relevant for the repair, was assessed before the visit. When Sandip came to my house he was fully aware and prepared. He fixed the boiler, charged an honest and fair amount and even followed up on the next day. All other companies will charge you for going to the house just to look at the boiler, despite whatever you tell them. Sandip is different, I told him the Fault Code, what happened, and he went to the house to promptly help. A top notch professional!

Sandip is honest, reliable and trustworthy! A combination which is hard to find especially related to Gas and plumbing. Whenever I need a professional, Sandip if my first and only call. He has a great way to simplify technical problems into easy to understand outcomes, his knowledge of the trade is first class. Hands down I would recommend Sandip without hesitation. Keep up the great work GasWiz!

Sandip is consistently professional and diligent in all his work. He always explained the work that needed doing, simplified complex systems and went above and beyond to make sure that we had the best possible set up during every stage of our renovations over 6 months. I'd have no hesitation in using Sandip again or in recommending him to family and friends.

Sandip has been exceptional - it's not often you get honest, transparent and competitive tradesmen, but sandip ticks all boxes. He lead all plumbing and heating works throughout my newbuild project and separately a full renovation. He found unique solutions and always found ways to give us what we wanted without compromise. However he was firm enough to advise us what was not a good idea, really demonstrating his clear communication. Sandip has gone well above and beyond in sharing tips to ensure all plumbing works and 2nd fixtures are of the highest quality giving us the peace of mind that our showers, bathrooms, toilets and underfloor heating is fit for a very very long time. We are particularly happy about his recommendation about the under floor heating system which has been a treat this winter, and his recommendation on water softners brands and hot water taps, sourcing great deals for us. He has always followed up on any questions we have had from our completion 6 months ago and honestly couldn't recommend him and his works competitively enough! Finally, no conversation is complete without price, sandip offers exceptional value for what you are getting.

Sundip has recently worked on replacing the water and drainage system for our house extension including replacing the boiler, installing the megaflow, the underfloor heating and bathroom fixtures. Very professional service from start to finish. Even after the work has been completed, he has been very approachable and fixed any minor issues that have arisen in a timely manner. Great service. Very pleased and highly recommended.
