I was very pleased with the service provided. The plumbing engineer called out to me was patient, prompt and professional. I was also very satisfied with the administrive team who were also patient. I would recommend them and use them again.

Great work and quick to get here
Customer Service
Our gas was turned off when the British Gas man who was fitting a Smart Meter found we had a gas leak. South Thames Gas were able to come out within a couple of hours and fix it. They were very professional and helpful and we were able to turn our central heating back on. I would recommend them unconditionally.

trusted and quality service
Customer Service
I have used South Thames Gas a number of times and have always been completely satisfied with their work. The employee who comes is always helpful, cheerful and stays to complete the job whether it is to do with plumbing, the boiler or the central heating system. No job is too small: we had to call them in for a blocked sink recently and this was dealt with speedily. The office too is extremely helpful in organising the work and always keeps in touch if necessary.

Highly recommended gas contractor
Customer Service
Remove existing fan from Worcester Bosch 24iJr boiler and supply and fit new fan. The work was carried out promptly and the time of the resident's choosing. The repair was 100 percent effective.

Best plumbers and heating engineers we've ever had
Customer Service
We run a property business and Michael and Donna at South Thames Gas are the best plumbers and heating engineers we have ever had. On quite a few occasions over the years they have gone way above the call of duty and come to our rescue, like when our heating broke in very cold weather and when we have had serious leaks. We wouldn't use any other company, and Michael and Donna are two of the nicest people you could wish to meet. They are very honest and the work is of an excellent standard.

Excellent installation and servicing
Customer Service
I needed a new boiler and South Thames Gas discussed with me the options available, arranged supply and fitted the boiler. They were helpful and efficient and I would have no hesitation in recommending them. They also are undertaking routine service visits on the boiler and again they are efficient and courteous
