Recently did a LLGS at a property with said boiler. All ok on gas check and results as expected. All nice and as per the book. Tenants neighbour collared me on way out and told me that boiler sometimes makes noises like a chugging train. No common thread times of day etc. whilst I was there I had the boiler on throughout and couldn't find anything untoward. Asked neighbour and tenant to monitor and let me know if the problem persisted. Anyway the neighbour has now uploaded a small video to YouTube with problem noise.

Has anyone experienced this before or any idea what might cause it?
Thanks
