What is the NPV of the Sunrise acquisition
ash to shareholders this year.
The other major factor here is continuous innovation across our product and technology road maps. In Holland, VodafoneZiggo is rolling out a nationwide one gig network. They were the first to roll out 5G, and they've embraced our Horizon entertainment platform. And that sort of innovation is occurring across the European footprint. It all begins with network superiority in markets like the U.K., for example, where Project Lighting has been a resounding success. In fact, we've included the latest figures in the appendix of this deck, so check them out. And we continue to be bullish on continued expansion of Lightning. We're also working on a clear path to 10G or 10 gigabits per second using a combination of HSC and fiber to the home. The pace of innovation of 5G mobile is equally critical, with VodafoneZiggo and Sunrise and others leading the way in their markets.
Robust and reliable network support innovation and connectivity, which is where this all began, and we've led the way with smart and intelligent WiFi and better, faster and cheaper CPE. And then finally, our entertainment platform continues to delight customers with the best user interface, seamless integration of apps, voice control and tons of other features. And importantly, Horizon has also laid the groundwork for our migration to an all IP video services platform with our Apollo Box. This is network agnostic, app centric, portable and low cost. This is where the entertainment business is headed. And we're leading the way again in Europe. Now our success in Holland and Belgium really underscore our excitement about the Sunrise acquisition, which we recap a bit for you on Slide seven.
The main driver here is scale. UPC and Sunrise together create a clear number two to Swisscom, one of Europe's most attractive and stable markets, with around a 30% share across all services and a significant opportunity to grab meaningful share in B2B. Now like our other FMC deals, the combination is anchored in best-in-class networks. Right out of the gate, UPC Sunrise will reach 90% of the fixed market with one gig services. Now they'll have leadership in 4G mobile and the largest and fastest 5G network in the country. Now the synergies are also substantial. You'd expect that with an NPV of over CHF three billion, about 80% of which is attributable to opex and capex efficiencies. The real opportunity here is to deliver the sort of combined financial growth profile that we've seen in Holland.
I'm not saying the numbers will be the exact same, but we're convinced that scale, market strength and synergies will deliver stable free cash flow for a very, very long time. It's also worth mentioning that both operations had a strong Q3. As you can see from the charts on the right, UPC continues to deliver improved subscriber trends with a record sales month for mobile in September and consistent improvement in broadband. Sunrise released their results earlier today, also a very strong quarter with positive service revenue growth despite roaming headwinds, positive EBITDA growth, which reflects strong cost management. They also delivered their best quarter of postpaid mobile ads in a decade and really strong broadband and TV customer growth. So far, the premerger integration work here has validated the synergy estimates and clearly establish the opportunity for Sunrise and UPC together to give Swisscom a run for its money.
I'll end on Slide eight with a quick look at Liberty Global, what we look like pro forma for both the Swiss and the U.K. transactions. Now most of you know this, but it's really, really important to continually reinforce the narrative of how we've transformed this company. After spending over a decade, consolidating cable and chasing broadband market share, we saw the fixed mobile convergence story developing in Europe around five years ago. Around that time, the incumbent telcos started prioritizing their fixed networks and broadband growth together with wireless. And they left the other three to four mobile operators struggling to com
