Hi. I have a Victorian terrace with bare openings in my chimney breast. In 2009, I used a fireplace company on the High Street (in London) to install a cast iron insert and slate hearth (i.e. an open fireplace). It was something like this: https://www.flames.co.uk/cast-iron-inserts/gallery-henley-insert.html
I don't recall ever receiving a HETAS certificate (only just heard of it today). The fireplace shop is no longer in business, so can't ask them.
Did I need to get a HETAS certificate for this type of job in 2009? I am wondering if HETAS only applies to stoves? Does it apply also to open fireplaces in 2009?
