Green Deal Guide

Please be advised that there has been changes to the PAS 2030 and the Green Deal Code of Practice.

The latest edition of the PAS 2030: 2014 Edition 1 is now available on the BSI website and the Green Deal Code of Practice Version 4 is now available to view on the Green Deal Oversight Body website

    • Green Deal is the Government’s leading environmental initiative allowing homeowners to finance the installation of energy efficient measures such as windows and doors - through the future savings on their energy bills.

      All Green Deal work is subject to the ‘Golden Rule’ which states that any additional charge on a homeowner’s energy bills to pay for the installation of the energy efficiency measures should be less than the expected savings through improved energy efficiency over the specified period.

      Who can become a Green Deal Certified Installer?

      Only companies who are certified by a Green Deal Certification Body (e.g. FENSA) against PAS 2030 to become a Green Deal Certified Installer can install Green Deal measures.

      Who can register with FENSA for Green Deal?

      • All FENSA registered businesses
      • Fenestration businesses registered with other glazing Competent Persons Schemes
      • Fenestration businesses not currently registered with any Certification Body

      Why be Green Deal Certified

      • New avenues to Markets
      • Scheme promoted by Government
      • Increased kudos for installation companies
      • Opportunity to develop business contacts

    • FENSA is a UKAS Green Deal Certification body which provides assessments for installation companies to become certified as a Green Deal Certified Installer.

      FENSA Green Deal Certification is for the installation of replacement energy efficient glazing and doors including replacement Insulating Glass Units (IGU) only.

      FENSA has developed an efficient route to Green Deal Certified Installer status. This has been achieved through partnership with its approved inspectors – the British Board of Agrément (BBA).

      FENSA has achieved accreditation by UKAS (United Kingdom Accreditation Service) as a ‘Certification Body’ to BS EN 45011: 1998.

    • To become a Green Deal Certified Installer companies will need to pass a Green Deal Office Audit and an On-Site Inspection carried out by FENSA approved inspectors.

      On the subsequent pages of this guide we outline what that involves. However, the detailed requirements are outlined in a document called PAS 2030 Improving the Energy Efficiency of existing buildings:

      Specification for installation process, process management and service provision, which is issued by BSI and is currently available from their website: shop.bsigroup.com Please note it is a requirement for the installer to hold a current copy of PAS 2030 for their own information.

      Installation companies will also need to sign up to the Green Deal Code of Practice (GD COP) and have copies available for both staff and improver/bill payer. A copy of this document is available on the Green Deal Oversight and Registration Body (GD ORB) web Site: gdorb.decc.gov.uk
      Green Deal Certified installers will most likely operate through a Green Deal Provider (GDP) as they do not usually have initial direct contact with the homeowner. The Green Deal contract is negotiated between the homeowner and the GDP.

      The GDP is the counter-signatory to the Green Deal Plan and responsible for both the provision of finance and arranging Green Deal energy efficiency (in this case windows and doors) works with homeowners. To become a subcontractor of a GDP, installation companies will need to make contact with GDPs directly a full list of certified GDP’s is available at the Green Deal Oversight and Registration Body (GD ORB) website at www.greendealorb.co.uk

    • Here is a summary of how the Green Deal process works:

      • A Green Deal Assessor undertakes an assessment of the property and energy usage
      • The Green Deal Assessor provides a report which identifies the energy efficiency measures.
      • A Green Deal Provider will then offer a low interest loan for the installation of the measure
      • The Green Deal installer then installs the measure
      • The improver/bill payer then repays the loan through their utility bill.

      The Green Deal Certification Body (i.e. FENSA):

      • Once certified, will register the Green Deal installer with the Green Deal Oversight & Registration Body (GD ORB)
      • Conducts both ongoing and annual surveillance of the Green Deal Installer
      • Updates Green Deal Orb website of any changes in status of the Green Deal Installer

      The GDP

      • Pays the installer
      • Notifies the consumer's energy supplier.
      • Provides an Energy Performance Certificate (EPC) to the homeowner.

      The Energy Supplier
      • Updates homeowners’ records with the details of the Green Deal Package and adds a charge to their regular utility bill.


      If required, planning permission and consent from Building Control should be obtained by the homeowner before signing up to the package. Green Deal Installers who are also registered with a Competent Person scheme for the type of work being undertaken can notify their compliance with Building Regulations in the usual manner.

      Installers must keep the Green Deal Provider informed, particularly if there are any changes (e.g. homeowner changes specification or products). This is vital as the installer is contracted and paid by the GDP (not the homeowner).

    • Full audits are carried out annually of both the head office and at least one site by prior arrangement on the anniversary of certification.
