New gas fire and fire surround. Help please!

[LazyDoll]

Just that.

Lived in property for 10 years and just getting round to properly decorating lounge.

Need to get rid of existing cheap/dated fireplace and put in new one and new hearth (?) and mantle etc.

Literally do not know where to start/look and all I know is we don’t want a log burner!!

Any help appreciated please

I got a gas insert fire fitted last year. Similar to the photo. Works by remote control. I think it looks really good and it’s very warm.
