Support for One Stop Shops

Find the support and guidance you need to successfully deliver retrofit work through our One Shop Shop grant scheme.

Registered One Stop Shop providers

Once registered, One Stop Shop (OSS) providers will have access to a designated OSS SharePoint page, designed to support you through the One Stop Shop process. There, you will find a full range of guidance and support documents to help you process grants for your customers.

Our online portal is where registered One Stop Shops providers can manage grant applications and payment requests. Check the OSS Scheme Documents for our Web Portal User Guide.

Designer / Installer Lead Approach

Phase 1. Application of Programme Specific Heat Loss Indicator Flexibility

The Heat Loss Indicator (HLI) requirement threshold of 2.3 W/K.m² or less, for a property to be eligible for a heat pump grant no longer applies to the installation of heat pumps on the following programmes:

National Home Energy Upgrade Scheme (One Stop Shop scheme)
Community Energy Grant Programme.
Warmer Homes Scheme

This is phase one of a Designer / Installer lead approach to determining heat pump grant eligibility. This is supported by a focus on a whole house retrofit design approach that considers potential fabric upgrades and a heat system design.

Other factors supporting the Designer/Installer led approach are as follows.

Increased market maturity and awareness of industry standards.
Increased focus on appropriate design, sizing, installation standards, commissioning, set up and maintenance.
System performance analysis of real-world data under varying heat loss conditions.
On-going development of quality assurance structures.

Heat pump grant eligibility requirement with respect to the heat loss indicator (HLI)

Scheme name	Grant Eligibility (HLI)
Better Energy Homes (BEH)	HLI <=2.3 W/ (K.m²) ^a
Community Energy Grants (CEG)	Designer / installer led approach ^b
One Stop Shop (OSS)	Designer / installer led approach ^b
Warmer Homes Scheme (WHS)	As per the WHS operational requirements.
Energy Efficiency Obligation Scheme (EEOS)	HLI <=2.3 W/ (K.m²) for deemed scores ^c Designer / installer led approach ^b for homes notified under the Residential / Energy Poverty targets ^d

Notes related to the table above

a. No change to heat pump eligibility, operational or payment requirements under BEH.
b. Designers may utilise their own design tools / software to support their heating and emitter design.
c. This HLI level is also required under EEOS for homes notified towards the Residential/Energy Poverty targets which do not achieve at least a BER B rating.
d. Subject to these achieving at least a BER B rating

Works must be completed in accordance with the SEAI Domestic Technical Standards & Specification.

Guidance documents

These guidance documents will support you and your organisation as a One Stop Shop. Learn everything from the rules of the One Stop Shop scheme, to how you can process Home Energy Assessments and retrofit works.

All One Stop Shops must be familiar with the terms and conditions of the Operational Grant rules. Registered One Stop Shops are responsible for ensuring that all relevant staff members, sub-contractors, partners, and clients are up-to-date in their understanding of the guidelines.

National Energy Upgrade Scheme Guidelines

This document sets out the minimum requirements reflected in each One Stop Shop Customer Agreement. All One Stop Shops are required to implement these minimum requirements in all One Stop Shop Customer Agreements.

One Stop Shop Customer Agreement Minimum Requirements

This sample Home Energy Assessment (HEA) shows you what carrying out an energy assessment as a One Stop Shop looks like.

All registered One Stop Shop providers can access a full HEA guide which can be found in the onboarding pack.

Sample Home Energy Assessment (HEA)

This document is a template Declaration of Works (DoW) form which needs to be completed and submitted when retrofit works are completed as part of the One Stop Shop scheme.

As part of the onboarding process, a member of the SEAI grants team will provide you with a demonstration of how to complete the Declaration of Works form

Declaration of Works form

This guidance document provides a structured framework to guide collaboration among building professionals, clients, and One Stop Shops. It works to simplify the OSS process for retrofit and renovation projects, clarifies roles and responsibilities, and includes links to relevant standards and resources.

R290 High Temperature Heat Pump Pilot

Guidance for One Stop Shops

This pilot is aimed at installing high temperature heat pumps (HTHP) in 100 homes to evaluate system performance, energy use, indoor comfort levels and heating patterns. This data will also help to assess the overall efficiency, running costs and performance of HTHPs for different home types. This pilot will be delivered through registered One Stop Shops. If you are working on a home that would be suited to this pilot, please get in touch.
