South Thames gas Ltd Reviews 

The customer service from Donna was fantastic. First time for a long time that I’ve had warm and helpful customer service. Michael the engineer was thorough and I felt in very safe and experienced hands - he was clearly very knowledgeable. There is a clear reason this firm has Worcester Bosch accreditation as their level of work is of a high standard. Donna and Michael kept in contact throughout the job and I now have a boiler installed and guaranteed for 10 years as well as them registering it with the relevant registers. They navigated everything for me. Thank you South Thames Gas!

Terrible - don’t use. They came out. Found the drip. Couldn’t say what part it was. Couldn’t say how they can fix it. Said it would cost a lot. Said they would order the part. In the meantime stuck a plastic bag inside the boiler to protect the electrics until i raised safety concerns. Then turned off the wrong pipe leaving me to actually turn off the water. Failed to respond to my complaint

I booked a boiler service with them, and they gave me a date and time slot.
I called again to make sure they had the booking.They confirmed it.
I called again on the morning of the booking, no answer.I tried many times and NO ANSWER
I found another number for them. I told the man about the booking, he was vague and unable to confirm anything and said he would call back in about an hour. He did not call back

I had a gas safety check done the same day I rang. The follow up work which included new boiler, fitting new cooker and capping off gas fire we’re all done very efficiently and at estimated cost.
Donna when I rang acted on all my queries and questions efficiently.
Michael was very respectful to my property. He tidied up any mess and all work was done to a high standard.
I was very happy with the overall service from beginning to end.

Just had a visit from a lovely engineer from this company - Michael. He was so polite & respectful to my elderly father. He was thorough in his inspection of the water heater that wasn’t working, opened it up & found a simple fault, thank God we decided on a second opinion as the first company we contacted - Plumb London came had a Quick Look, didn’t do much & later quoted over a thousand pounds to replace the water heater.
Don’t hesitate to contact this company - they know what they’re doing.
Thank you💖🙏🏾💖

I had a new boiler installed and was really pleased with the service. The engineer arrived on time, completed the job within the agreed budget, and took the time to show me how to use the controls. He was also very clean and tidy throughout. Would highly recommend.

Last Friday my kitchen tap would not turn off the hot water. I managed to stop the flow below the sink but contacted South Thames gas immediately after googling possible issues. I am so glad I did- it was far beyond my ability to sort out and that same day an engineer came around and diagnosed my tap needed replacement. They quoted a very reasonable price which made me even happier I hadn’t tried to struggle on without water. I assumed it might be a week or more before the new tap arrived. But no, around midday Donna called and advised the part was in and an engineer could be round this afternoon. I was blown away by the organisation and efficiency with which the repair was done- just 2and a half hours after the call. Everything was completely cleaned up after and I was super happy with both the service and the interactions. I will now only use South Thames gas and feel assured they give prompt polite efficient service with accurate and fair quotation
I have an old boiler which will soon need replacement and I feel much happier now I can rely on this company.

AVOID - Had them service an 11 month old boiler and the chap gave me a list of things that need correcting. None of the items were necessary including magnetic limescale filter etc. (other reviews mention this) When I asked the the engineer about the items he turned very aggressive towards me. As a result I contact the original installers to check that the installation was up to standard and it was. I then had another well known company service the boiler and everything was fine.
Just avoid at all costs.

Our boiler stopped working. A plumber from South Thames Gas came out around 10pm and diagnosed a faulty pump. We were charged £177 for his visit.

We were sent a list of recommendations including a new pump & pressure sensor (total cost including VAT £614.99).

They also suggested a magnetic filter & scale reducer, for which we were quoted £370.00 + Vat (£74) and a room thermostat £298.99 + VAT (£58).

This makes a grand total of £1,415.98. Plus the cost of the initial assessment visit, it makes a grand total of £1,592.98.

Thinking I could buy a new boiler for this, I started contacting other heating engineers.

Luckily for me I found another one who told me that there was no need for a new pump!

He fitted a new pressure sensor and room thermostat. (Unfortunately a magnetic filter could not be fitted as the boiler is only around 40cms off the ground.)

I paid him a grand total of £390 and the boiler is now back up and running!

Thank goodness I didn't use South Thames Gas!

I called South Thames Gas to service my boiler on the 30/052022.
The engineer came between the times agreed and explained what he was going to do.
He undertook a full service (much better than the previous company I had use).
It was so refreshing to have a tradesman who is friendly and polite.
I would highly recommend this company and would definitely use them in the future if needed

Timer stoped working in a time of Covid. took almost a week for the order to arrive. This is not their fault. Soon it arrived the fitted timer the next day.
Clean and tidy work.
Very happy with South Thames work.

Lovely people, prompt service even in a pandemic, didn't charge me for things I didn't need, it feels amazing to have a proper boiler again.

AVOID these guys. Terrible Service. Late attendance. Massively overcharged. Said they'd come to finish off part of the job and didn't. We then needed someone else to come and fix what they did. I have never written a negative review of anything, but feel compelled to warn prospective customers about South Thames Gas. Find someone else!!!

Having seen the reply below, I’ve no desire to get into an argument but the second attempt at fixing the issue with a solid pipe failed. We required someone to come and fix this, and the damage to the wooden panel caused by the first attempt by South Thames Gas. For the two trips to try and fix the leaking toilet we were charged over £1100.

Had a faulty mid position actuator.
Got in contact with South Thames Gas and made an appointment for an engineer to sort it out.
Prompt and faultless service.
Would highly recommend.
