@Gavin26 while simple boosters can help having multiple ones in a single home is not ideal as each booster halves the bsndwidth devices can access so iff 2 are dasy chained the furthest booster can only supply roughly a quarter of the speed.
These days there are far better alternatives which created a wifi mesh in your home. Sky market their own version called Wifi Max which codts an additional £7.50 a month and provides a modern router and up to 3 extenders if a broadband engineer agrees you need them.
Alternatively you can buy a third party kit which can be cheaper in the long run. These are quite easy to set up in what is known as Access Point mode they connect to the Sky hub by ethernet after turning off the hub's own wifi. You place the satellite units to optimise coverage using the systems app. My own system gives me 200Mb/s in every room of my 3 level home for an outlay of £100 but each home is different. Loads of choice at verious price points but units from TP-Link and Netgear are popular.
