This follows the addition of the 24-hour Super HD channels Polsat Sport Premium 1 and Polsat Sport Premium 2, as well as four pay-pay-view services from Polsat Sport Premium, to its offer.
The channels will also be available on the Horizon Go mobile TV service.
The first Champions League play-offs will be shown live from August 21 and the group stages of the Europa League from September 20.
Commenting on the development, Robert Redeleanu, CEO of UPC Polska, said: “We are constantly developing our TV entertainment offer and believe that nothing gives football fans such emotions as access to world-class competitions. Thanks to our cooperation with Polsat, UPC customers will be able to watch the matches of the Champions League and the Europa League live in very good transmission quality for the next three years. It will be a perfect complement to the attractive set of sports events available at UPC, such as Bundesliga, Serie A and La Liga. This is yet more proof of our commitment to providing high-quality content that strengthens our best brand on the Polish market in the field of internet and TV entertainment.”
