Decking installers in Northern Ireland

Northern Ireland has its own permitted development order and the district councils handle planning. Belfast's suburbs slope towards the Lagan, Newry climbs its valley sides, and rainfall across the province is high, so most installers here fit composite on a ventilated frame and design raised decks with proper guarding.

Planning in Northern Ireland

In Northern Ireland the householder rules follow the same pattern as England: a low deck behind the house that keeps within the garden-coverage limit is permitted development, while a raised platform, a deck in front of the house, or one at a flat or listed building needs an application to the council, which is the planning authority.
