Copy Row to Separate Sheet if Cell Contains Certain Text

Hi
I've been trying very unsuccessfully to write some existing code which will copy rows of information if a specific cell in that row contains some specific characters. If a cell in column E contains the "P1" anywhere in a string of text I need to copy the whole row to another sheet. Happy to share the code I have or an example sheet if people think it will be useful.
Thanks in advance.
