UK Racing event Filters

does this offer us to filter racing events for example only NH races or handicap only? 
is there a way to only bet on events i want 

Yes, you can delete markets that do not fit a certain criterion. 

See an example here.

You can also search specifically for the markets you need.

In your case, you can use Market Locator to load only the markets that have a certain pattern in their names, for example "Hcap" for Handicap.

great thank you,
is there a way to filter flat racing and all weather? 

As long as there is some indication of those race qualities in the name of the race. If BetFair does not provide this information anywhere, then it is not possible to filter them out by that parameter in MF Pro.
