My floor joist has been damaged by fire. See attached photos. 

How do I URGENTLY repair this?

Hello @SPP 

I'm sorry to hear that your floor got damaged by fire. In this particular instance, I propose engaging the services of a registered builder so that they can assess if the beam under your floor will need to be fully replaced or can be cut and linked to a new one. The floor panels will generally be replaced with new ones. Before starting, its best to make sure that it is safe to start repair works. Make sure to get the all clear from the relevant trades such as electricians, gas fitters and any other local authorities.

Let me call on our experienced members such as @Dave-1 and @Nailbag for their recommendations.

If you need further assistance, please let us know.

Thanks @EricL 

Yep, I will have this looked at. 

Most likely, I think this will require some timber on either side of the burnt joist to support the load. Sistering joints is the phrase I have heard.
