FRAMEWORK AGREEMENT GUIDEFor timber window and door products
WHY WORK WITH LHC?
These are the key reasons to work with LHC
whether you’re a public sector organisation
looking for procurement solutions or a supplier
with products or services to provide.
Knowledge and experience of procurement Our organisation began half a century ago and over five decades we’ve developed and shaped our service to meet the evolving needs of our clients.
Recognised technical expertise Our technical expertise is built on continuous research by our team of technical specialists who consult with clients on the outcomes they need and suppliers on the range of available solutions.
Commitment to better buildings and homes Our ultimate goal is helping our clients deliver better environments for the communities they serve, a goal we support through our frameworks, that address every aspect of quality, and our selection of the most appropriate suppliers.
Fast and efficient procurement Once LHC Appointed Companies are established for a framework, the process of calling off projects and commissioning work is very efficient. Terms and rates have been agreed and even when a mini competition is required, the majority of contractual arrangements have already been finalised. Project work can start quickly.
Financial gains Working with LHC frameworks gives suppliers access to construction, refurbishment and maintenance projects of over £200m each financial year. Clients who spend more than £200,000 on two or more frameworks in a year will benefit from a share in the LHC operating surplus we return to Members.
Please read this guide in conjunction with the LHC guide to understanding and using pre-tendered frameworks, available on our website.

About this framework agreement
LHC.GOV.UK
LHC Appointed Companies are selected based on price, essential requirements, a range of qualitative assessments and a structured interview
05
About the tender
Interested companies were invited to complete a Pre-Qualification
Questionnaire (PQQ), which sought detailed information on
several criteria, prepared and formatted in accordance with
PAS 91:2013 ‘Construction pre-qualification questionnaires’,
before inviting selected companies to complete an ITT and
Offer Document.
PAS 91:2013 was published by the British Standards Institution and sponsored by the Department for Business, Innovation and Skills (BIS) to provide a consistent set of pre-qualification questions to be used throughout construction procurement.
Stage 1: Selection criteria Stage 2: Invitation to tender
-- Economic and financial standing
-- Employment practices
-- Health and safety management
-- Sustainable and environmental management
-- Technical capacity including quality management
-- Experience of working in public sector properties
-- Managerial capability, product range and support
-- Technical support provided to the client
-- Compliance with EU/UK legislation
-- Quality management and procedures
-- Equal opportunities and diversity
The companies that scored sufficient marks in the PQQ were invited to complete an offer document (invitation to tender).
The offer document provided detailed service and product specifications and sought a response from companies on their conformity to these requirements.
LHC.GOV.UK
The diagram below shows the process a supplier completes to become
an LHC Appointed Company and to be awarded a contract (or “call-off”).
It also highlights the support LHC provides once a project is live.
From pre-qualification to call-off contract
When buyers are ready to choose a supplier for an individual project
they should start the process by talking to LHC. LHC will coordinate
either a direct award, if there is a single supplier on a framework,
or a mini-competition if there are several.
-- A mini-competition involves all capable LHC Appointed Companies
-- A direct award is made to a single company, with justifiable
reasoning, without reopening competition
Awarding contracts “Call-offs”
LHC provides support and technical assistance throughout
the life of a project, as required:
-- To ensure high quality standards are maintained
-- Service levels are fulfilled
-- Delivery periods are met
LHC also welcomes discussion and feedback on completion of projects
Works commence/complete
Pre-qualification questionnaire
Appointing companies
Selected suppliers submit offer documents covering:
-- Specification for products and services

each evaluation criteria.
A detailed evaluation report is prepared which shows
for each tenderer a:
-- Weighted score under each heading
-- Value for money index
-- Company or companies recommended for appointment
Offer documents and evaluation
Pre-qualification questionnaire

-- Company standing
-- Financial standing employment practises environmental
awareness capacity and geographical range
-- Installation capability
-- Technical capability
-- Quality systems management capability
-- Experience of supply to the public sector
-- Sustainability and social value
Our aim is giving LHC clients and Members a choice of Appointed
Companies to work with. Numbers vary per framework in line with
anticipated demand and subject to the number of qualifying suppliers.
-- All suppliers are notified of the results and the unsuccessful
tenderers can choose to have a debriefing to help improve future offers
-- Contract Award Notices are published in the Official Journal of the
European Union (QJEU) and on the LHC website
