Your PIP report may be of assistance to your ESA appeal, but you need to be aware that it will only address part of the test. PIP is a walking test, however, ESA looks at your Mobility which includes your ability to self-propel a manual wheelchair over the same distances. You do not need to use or even own a wheelchair for the test to be applied as long as the usage is considered to be reasonable.
So you will need to show that this usage would not be reasonable, this may be dues to physical problems that would limit or prevent you using one, it may be due to medical advice not to use one or it may be due to the practicality of your using one.
Have a look at the ESA Claim guides for more information.
