There's a good chance it's the fan failing. Worth getting it checked quickly as in-built protection on the boiler will prevent firing of the burner if the fan stops working; ie no heating or hot water...

If its a combi check outside drain pipe for blockages

It could be your fan (bearings gone) or hopefully just air in the system. Is it a combi boiler? Try and vent the rads and check your heating pressure (if its a combi ).
