We contacted CST Group for Bains Liquid Waste a couple of times last week under emergency circumstances for a couple of our clients. They managed to squeeze us into their already busy day. Very grateful they could attend. The ladies I organised it with communicated back to me and kept me up to date with scheduling. Thank you

Very happy with the service CST provide. They reach out with a reminder when your next service is due. Clear communication over the phone, via messages and in person. Friendly staff who were happy to work around the tricky location of the sewage access point. They did a great job. Handy to have a service card to see what was checked and noted when the next service is due. Thank you CST!

CST Group are so great to deal with, really helpful and friendly on the phone scheduling a time to come. Gareth has just been and completed a septic tank service for us, a first time for us having only moved here a few years ago. He arrived on time (actually ahead of time) and was super helpful, explaining the system to my husband and giving us all the information we need. Really appreciate your service, thanks so much Gareth and the team!
