One Stop Shop
SEAI's bundled deep-retrofit service - a registered provider manages the whole job, from assessment to contractor to grant paperwork, and deducts the grant upfront.
A One Stop Shop is a registered provider that manages a home-energy upgrade end to end: a home energy assessment, applying for and combining all relevant SEAI grants, project-managing the works, assigning contractors, deducting the grant value upfront from the homeowner's bill, and a follow-up BER assessment once the works are done. It's the route SEAI backs for a full deep retrofit rather than a single measure. To qualify, a home generally needs to have been built and occupied before 2011, and reach either a post-works BER of B or a heat-pump installation with a primary-energy-demand reduction of 100 kWh/m²/yr.
For retrofit-adjacent trades - insulation, heat-pump installers, electricians, ventilation contractors - a One Stop Shop project bundles several trade packages into a single procurement, so winning the coordinating role (or a slot as a subcontractor to it) can be worth several single-measure jobs at once.
PlanningLeads' free Home Energy & Grant Report flags whether a home looks like a One Stop Shop / deep-retrofit candidate from its age and current heating type, and estimates the bundled grant value and resulting BER uplift.

Common questions
It manages the whole upgrade for you - assessment, grant application, contractor appointment, project management and the final BER check - rather than you coordinating each trade and grant separately.
No - the One Stop Shop applies for and combines your grants with SEAI and deducts the value from your bill upfront, so you don't handle that paperwork yourself.
The grant amounts are the same either way; a One Stop Shop charges for the coordination and project-management service, which some homeowners find worth the convenience and others don't.
