The verdict
If Sky TV is already in your life, bundling broadband can be convenient and well-priced — at least until the annual increases kick in. If you just want the best-served pipe into the house at a price that stays put, Zen is the cleaner buy.
Choose Zen if…
- You don't want TV in the bundle — you just want excellent broadband
- You want a fixed price and an easy exit calculation
- Service quality is the reason you're switching in the first place
Choose Sky if…
- You want Sky TV/Glass and one bill for everything
- A bundle discount makes the combined price genuinely cheaper for things you'd buy anyway
