Gates is penned by a team of writers whose credits include My Family, Green Wing and Not Going Out, while Jennifer Saunders is the script editor for episode one.
Miranda star Tom Ellis is also among the confirmed cast.
Gates will explore the humour that happens between parents during the moments that they pick up and drop off their kids at school.
The programme will poke fun at the "unforgiving, socially-exposed political minefield" of the school gates, where "your children choose your friends".
Gates is part of Sky1's autumn lineup, which is focussed on brand new homegrown comedies such as supermarket-based series Trollied and the Sally Lindsay comedy drama Mount Pleasant.
"I'm so pleased with this autumn's lineup as it feels like a huge mark in the sand for Sky1 HD. Two years ago we promised customers we'd bring them the best in British comedy and here it is," said Sky1's director Stuart Murphy.
"We've worked really hard with the best British talent across all genres to make sure customers feel Sky1 HD is a premium channel."
