It should work if you have the Sky+ HD since it is compatible with the Low-Noise Block (LNB) downconverter with the Freesats and for Q with a Hybrid LNB, however usually engineer will replace LNB entirely if you wont use freesat with Q only.
So yes you should still be able to enjoy your shows on your Freesat dish on Sky +.
Note however, that Sky+HD is an older system. Upgrade to Sky Q for no extra cost* to get access to apps**, larger hard drive***, 4K/UHD****, Multiroom, and more features never before seen on Sky+.
Or, if you can, look to switch to Sky Glass / Stream, the future of Sky without a dish. Cancel anytime*****.
* Cost of Sky Q Upgrade is usually free for all paying Sky + customers. Look for an email from them to confirm you are eligible.
** Availability of apps requires a Wi-Fi / Ethernet broadband connection with a minimum reccomended speed of 25 Mb/s. Connection via phone line is no longer supported on Q and hasn't been on Sky+ since 2013.
*** Larger Hard Drive statement depends on hard disk size of original Sky+ Box, and of the Q box. FOr reference I have said about 500GB sky+ and 1 TB sky Q.
**** 4K/UHD service requires a compatible TV , box, and UHD subscription. Not all channels support UHD.
***** You own the Sky Glass TV. For Stream you can cancel your subscription anytime by opting for a higher subscription price.
