Regarding chimneys I have to pay a bloke to come once a year to clean it. As Clive says its linked to the house insurance being valid.
A couple of years ago I didnt use my Chimney at all yet I still needed to pay the bloke to do it. He turns up & sticks the brush up the chimney once, absolutly spotless, he said "its already clean" ...i said yes I just need the certificate....he laughed and said your not the only one....
Its a function of the world we now live in. Basically its job creation - I had to hire a "trained certified expert" at Chimney sweeping (who incidently couldnt even open my Chimney, I had to show him how to do it). He then gives me a certificate which will be uploaded I imagine to some admin system someone else has to manage.
So the act of sticking a brush up a chimney has created multiple jobs ;
- The Chimney sweep (trainined certified)
- The Chimney sweep trainers (who train the would be chimney sweepers)
- The certificate management system admin operators (who maintain the chimney certificate database & all the paper work)
- The Chimney sweep watchdog - bound to be some group or other that has to regulate & control all this
.....I have probably missed several other functions. Welcome to the new world
