Home educators and other interested parties can contact their local constituency MP via They Work For You or by making an appointment at the local constituency surgery.
If you don't know the surgery times, you can usually find out by putting your MP's name into google.
While it is always better to add some personal touches to your letter, it could include some variant on the following:
Dear MPI am a home educating parent.
If a home educated young person under the age of 16 secures a place at the local FE college, can the local authority claim back funding for college tuition fees?
The Education Otherwise website has references to previous Government statements, where civil servants stated that it was not possible to issue a statement until after the Election. See http://www.education-otherwise.org/funding.htm.
I look forward to hearing from you
