Tv freezes and buffers all the time. I have been told there is something that plugs in to help with

Have been told to request a free plug in device to help with the signal around our house which will prevent the freezing and buffering.

@SheilaONeill  I am assuming you are referring to getting a Booster from Sky which they use to provide to help with Sky Q. As this is primarily a public customer help forum you are not addressing Sky so you would need to call them to discuss the matter.

One of the main reasons for buffering and freezing is the quality and speed of the WiFi signal being received at the TV/puck and not that being received at the router.  This can be checked with the Netflix App (Get help > Check network).  The minimum speeds recommended by Sky are as follows:

HD = 25mbps

UHD = 30mbps

HD + 1 puck = 30mbps

UHD + 1 puck = 35mbps

The important thing with Wi-Fi is to have a stable signal as both Glass and Stream are susceptible to problems if there is any signal fluctuation or interference.  For this reason an Ethernet connection is usually better than WiFi as it maintains better stability. If you try an Ethernet connection don’t forget to turn off WiFi in Settings / Network / Advance settings.

If this is not practical (as in my own home) then you could consider Powerline Adapters which are about £35 on Amazon.  Don’t waste money on a Gb model as Glass and Stream Ethernet ports only support 100mbps.
