Review Summary for TSG Building Services Plc

TSG Building Services Plc garners occasional praise for individual engineers who are described as polite, thorough, and effective, particularly in resolving urgent heating or hot water issues and performing gas checks; however, these positive experiences appear to be outliers within a broader pattern of significant dissatisfaction. The most common problems reported overwhelmingly concern poor communication, missed appointments, and extended periods without heating or hot water, with customer service frequently described as unhelpful or nonexistent. Additionally, there are recurring complaints about the quality of workmanship, with issues ranging from badly fitted components and damaged property to engineers leaving behind new problems after a visit, sometimes even implying deliberate damage or corner-cutting. The company appears best suited for social housing clients or those with contracts managed by local councils, given a significant portion of reviews mention council housing or contractors. Before ordering, potential customers should clarify expected response times for various services, the specific qualifications and training of the assigned engineers for complex installations, and the company's policy on rectifying shoddy work or addressing complaints, especially given allegations of aggressive staff and a disregard for safety.

We had TSG plumber Ross, round today to replace our toilet and bathroom. He has done an exceptional job. Was polite, cleaned up after his work. He communicated well with us to explain what was being done, asked which colour floor tiles we wanted. Can't recommend him enough.Well we tried the bath today, to have a shower, unfortunately found the bath narrower than our old bath, we both feel unsafe standing in the bath

Feel free to use this company if you want to be let down on more than 1,2 or even 3 occasions. Absolutely terrible service. The engineers constantly do not turn up and when you call customer services they give numerous excuses. Be prepared to be let down!

Received a letter informing me the gas boiler was due for inspection, I called then to explain I had an appointment that day and could I arrange a different date.I phoned the company and a women answered, I explained I was out of town on the date, she replied you can't cancel the appointment because you don't have an appointment. I said I have your letter here, she said angry YOU DON'T HAVE AN APPOINTMENT!and that was the end of the phone call.

I've worked for this company and can't believe what a horrible nasty bunch they are ,I hurt myself working for them and only thing they cared about was me signing something to put them in the clear,when I was given no training whatsoever,the guy in charge Bryan is a Wiesel and is such an outdated character ,apart from all that this company cuts corners with really serious stuff ie asbestos,and when there is children in properties the have no regard for safety and wellbeing avoid all this joke of a company at all costs
