Hi Mad dog lady
Welcome to the forum, you might want to have a look at the following FAQ which explains where everything is.
Welcome to Benefits and Work .
The answer to your question is no, now that you have moved in with your partner, their income and savings will be taken into consideration when you claim/apply for any means tested benefit such as UC, IR ESA, HB. If you have savings over £16k then it disqualifies you from claiming.
As PIP is not means tested then that will not change, I would put your information into one of the online benefit calculators just to check.
