Gas Safe Certificate?

[PowerFlusher2]

Hi,

I have a Baxi Bermuda wall mounted gas fire (with a back boiler) which I want to replace with a Valor Homeflame Harmony - binning the back boiler. Have spoken to a GSR and when I asked him to include 'will supply Certificate of Gas Safety' to GSR on the quote he said there was no need because it was an exchange as opposed to a new installation and him giving me a Certificate of Gas Safety is all that is required.

Is he right?
