Carbon monoxide

Apart from my engineer running late due to traffic, my service went well and I am now waiting for my certificate, thanks for your help :)

Good service and a brilliant company. For my location being on the edge of London is complicated for property services especially as engineers do not wish to travel that far. GSL got an engineer out the next day after booking, he was on time, completed the job nearly instantly and he was gone. I got my certificate 48 hours later and there was no complications. They say if it's too good to be true it probably is right? Not in this case! Cheers.

The feedback I have is only positive, the engineer was a quality chap and my gas certificate came on time after it was completed. Ill definitely consider your company shouldd I require a similar service.

Great service, professional staff and quick response time, impressive! I will be contacting you again soon.

Gas safety check completed by a gas safe registered engineer, which makes it a gas safe property. Thanks again.

Completing my CP12 has put me at ease, knowing it needs to be renewed feels like your on a time limit before your gas appliances go crazy. But it's all done now, thanks! :)

So relieved I spent my money on the right things. Great company and I got a great service, thank you.

The discount provided was good, the service was even better! Thank you for your help guys.

I was without an up to date gas certificate for my property for 2 days but you guys done the best you could and booked me in the earliest slot possible, thanks for being keen in helping me and finally completing the job.

I was politely asked to leave a review about my experience with gas safety landlords. It was without flaws, they were professional and punctual and the service was completed and passed successfully. Thanks.
