Revenues at SKY Ireland's business increased by £5m to £531m (€610.36m) last year, new figures show.
New accounts for the UK based SKY Subscribers Services Ltd reveal the Irish branch revenues last year increased from £526m to £531m.
A note attached to the accounts states that the Irish branch revenues relate to 'direct to home' pay television, broadband and telephony services here.
The revenues generated by SKY Ireland is almost three times the €196.2m An Post collected in TV licence fee income for RTE last year.
SKY Ireland has close to 700,000 subscribers here.
Overall revenues at Sky Subscribers Services Ltd increased marginally to £1.05 billion as pre-tax profits increased by 24.5% to £61m.
SKY's Irish revenues contributed to SKY UK Ltd revenues increasing by 4% from £9.8 billion to £10.2 billion last year.
The directors state that during the year, the SKY Group increased prices across TV and communication products "reflecting the additional value being provided in these areas".
Last year, SKY UK's programming costs reduced by £114m from £3.53 billion from £3.42 billion and the directors state that the decrease in programming costs is predominantly driven by the impact of the World Cup in the 2022/23 football season.
The staging of the World Cup in November and December put a hold on SKY's main sports product, the English Premier League from November 13 to December 26 last.
They state that "sales, general and administrative costs have grown due to increased marketing, logistics and other costs related to the launch and delivery of Sky Glass and Sky Stream, higher depreciation and amortisation on investment in technology and retail stores and higher technology costs driven by increased fibre subscribers".
The separate accounts for Sky Subscribers show that the "Irish branch" was the best performing part of the Sky Subscribers business as revenues from group support services declined by £1m from £521m to £520m.
On the impact of Brexit on SKY Subscribers Services Ltd, the directors state that "within the Irish branch, we have implemented additional compliance checks to ensure products placed on UK or Republic of Ireland markets comply with the relevant legislation."
The directors state that they have opened a warehouse in Dublin to supply product manufacturers in the EU which incurs duty and ensures that no products are moving across the Northern Ireland/Republic of Ireland borders.
They also say that extra costs have been incurred due to extra administration producing/managing customs clearance between the UK and the Republic ofIreland.
"To date, we are not aware of any significant changes to contracts or pricing from a SKY Ireland perspective," they add.
SKY employs just under 1,000 people in Ireland, across a range of functions including sales, marketing, finance, retail, support and customer service.
