After over two decades in marketing, Gary from Huddersfield chose to launch his own chimney sweeping business – Swept.

Gary enrolled on the H011 Sweeping Course at Mr Soot Training Centre in Wigan and found the course was everything he needed to gain the confidence and expertise to begin his journey as a chimney sweep.

I looked at a number of sweeping courses before deciding on the H011. For me, it was important that I not only had quality training, but also had the opportunity to become HETAS approved, as it’s a brand which is highly recognised and valued by customers.

The four day course at Mr Soot Training Centre in Wigan was really informative. David, Sam and the team were very welcoming and supportive. The course itself was thorough, and upon completing it, it gave me a good degree of confidence ahead of ‘going it alone’.

I’d definitely encourage anyone who is looking to get into chimney sweeping to book on the H011 HETAS course – highly recommended!
