Croesyceiliog is primarily a residential district and contains a wide variety of housing from Victorian terraces and even older Welsh cottages to property built between 1930 and 1970 and newer developments within the area. Most of the housing was built in the 1950s and 1960s as part of the development of Cwmbran New Town.
The main shopping precinct is Edlogan Square and contains, among others, a newsagent, a pharmacy, a grocer and a Fish & Chip Shop/Chinese Take-away. The 'Six in Hand', one of the area's two pubs, is also here: the other, 'The Upper Cock', is on The Highway. There is a smaller shopping precinct on North Road that includes a Co-operative Convenience store, hair salon and a doctor's surgery. There is an old/unused Texaco Petrol Station on The Highway and a corner shop & hair salon opposite 'The Upper Cock'. Adjacent to 'The Upper Cock' is Croesyceiliog Cricket and Rugby Club. Croesyceiliog Cricket Club currently play in the South Wales Premier League, while Croesyceiliog Rugby Club play in the Welsh Division Three East League. Croesyceiliog also has lawn bowls team which play at Woodland Road Sports Grounds.
The area is served by Croesyceiliog Comprehensive School, and a primary school on North Road (Croesyceiliog Primary School). There is a Baptist chapel on Chapel Lane, Pontrhydyrun Baptist Church  and an Anglican church named St Mary's Church  on Bryn Eglwys (literally 'Church Hill'). Woodland Road Park is a recreation area which contains a bowling green, rugby pitch, tennis courts, outdoor paddling pool and adventure playground.
The former Gwent County Hall  is located here. Until 2012 it provided the main administrative base for Monmouthshire County Council (even though it was outside that administrative area) and Gwent Police, and also some offices for Torfaen County Borough Council. As of 2012 the premises have been vacated for demolition due to concrete cancer.
The town, like many in Torfaen, is expanding. New housing estates have been built: Woodland View (2002) and Stonebridge Park (2006/7).
