External Window & Door Sets

& all associated works, goods & services

This framework is for use by contracting authorities across the UK to procure the new or continued services of system suppliers to supply and install external window and door sets, and all associated works, supplies and services, for both residential and non-residential property.

In managing the PVC-U, aluminium and timber-framed window and door replacement programmes it is expected that GRP/steel/communal entrance doorsets may also be supplied or installed, with those aspects delivered by specialists subcontracted by our appointed suppliers. 

Key features:

So if you want the budget spent on the property, not the procurement, B2G offers a compliant, cost effective route to clients who know what’s needed (eg. continuity of service, repetition of a successful formula, or capitalisation of time already invested planning/surveying etc) and need to get going.

Buyers: please contact us for more information and/or download the project registration form from this website. 

Suppliers & Lot

proven capability, nationwide

EWD22 is a single lot framework covering all parts of the UK, within which each Supplier can designate (and update) their active regions* and preferred project value ceilings and floors. This innovative approach delivers optimum procurement efficiency and minimum carbon footprint to the benefit of all parties. 

* Buyers may invite and contract any Supplier to deliver services anywhere in the UK, but to minimise carbon footprints and optimise procurement efficiency, Suppliers may decline Buyer invitations to submit bids to deliver services outside the Supplier's active region/s; and Buyers may restrict invitations to the Suppliers active inside the region/s (or neighbouring region/s) where service is to be delivered.

certification + case history = competence

We assure competency & proven experience with a focus on


"should cost" = sustainable + competitive

In line with the government’s Should Cost Modelling (SCM) we focus on achieving sustainable & competitive pricing rather than a race to the bottom. 

Bidders were required to submit discounts against national schedules and prices for all key OHP% and standard items.

As a result buyers enjoy clear benchmarked savings and clear cost control of all major line items.

Social Value

community benefit comes as standard

As a requirement for being appointed to the framework every bidder confirmed their willingness to actively support clients and deliver all measures which, depending on the size and nature of the Project and the needs of the local community, might include:

Local employment

Full & part time; apprenticeships; work experience

Supply chain

Local sub-contractors, suppliers, social enterprises, NGOs & charities

Supplies & equipment

Locally manufactured; reused or recycled; or sustainably sourced 

Community engagement

Educational (eg. engaging with local schools & colleges etc); social (eg. engaging with local clubs & charities etc); or environmental (eg. litter patrol & work parties etc)

Call Off Process

flexible and efficient

Buyers can award a contract direct to any supplier confident they will deliver to a quality that meets or exceeds all regulations and standards, at a price demonstrably below market average, and in full support of the Public Services (Social Value) Act 2012, thus generating commercial value for money AND social value for the community - embodying the principles of MEAT.


The Buyer registers the project with B2G 


The Buyer has the option to run a mini competition or to direct award a Project to any Supplier based on a wide range of factors, and based on their own preferred criteria or weightings, subject to ensuring that any action taken is transparent, non-discriminatory and fair. 


The Buyer contracts the Supplier using their preferred form of contract, which may be one of the JCT/SBCC, NEC or PPC/FAC/TAC suites of contracts or the Buyer’s modified version, or any other standard form of contract or Pre-Contract Service Agreements (PCSA)  used by the construction industry. 


The Supplier delivers the project according to the agreed terms and KPIs, and B2G monitors the project.

Price increases

Price increases (including for materials) can be applied in line with either BCIS (Building Cost Information Service) or RPI (Retail Price Index) or CPI (Consumer Price Index) using ONS (Office of National Statistics) data and applying the Framework’s month of launch as the base index.

A Prior Information Notice (PIN) was published on 22 October 2021; the Contract Notice (CN) was published on 23 January 2022; and the Contract Award Notice (CAN) was released for publication on 1 June 2022


24 requests for the ITT documentation were received. A submission date extension was requested and granted, and all active participants notified, and the framework webpage was also updated with the new submission date. 4 compliant bids were received on or before 11pm on 14 March 2022. No late submissions were received.


Our objective was to assure competent suppliers and competitive rates. We set the bar accordingly high. Each section of the bid document was scored separately, and weighted as follows:


Pursuant to Clause 87 of the Public Contracts Regulations 2015 preliminary award notices were issued to 4 bidders on 3 May 2022, each of whom share top rank for quality, price and VFM, and can each therefore be direct awarded to any project, by any contracting authority, anywhere in the UK. No challenges were received during standstill, and consequently Award Confirmations were sent to each bidder and the framework launched on 1 June 2022.
