Multi-site organisations bidding for UK government contracts must include emissions data from all operational sites in their Carbon Reduction Plan. According to the UK Government's PPN 06/21, the CRP covers the entire organisation's carbon footprint -- individual sites cannot be excluded regardless of size or data availability.
PPN 06/21 requires your Carbon Reduction Plan to cover your entire organisational carbon footprint, which by definition includes every operational site. There is no provision in the policy note for excluding locations based on size, geography, or data availability. The CRP template published by the UK Government asks for your organisation's total Scope 1, Scope 2, and selected Scope 3 emissions, and these totals must represent your entire organisational boundary as defined under the GHG Protocol Corporate Standard. According to the PPN 006 guidance notes, this applies to all central government contracts above the 5 million pound threshold, covering approximately 40 billion pounds worth of annual procurement spend.
The policy note applies universally across all contract types and sectors. Whether you operate two offices or two hundred warehouses, the expectation is the same: your CRP must capture the carbon footprint of everything within your organisational boundary. According to guidance published by the Crown Commercial Service in 2024, the most common interpretation error among multi-site organisations is assuming that only the site delivering the contract needs to be included. This is incorrect. The CRP is an organisational document, not a project-specific one. Every office, warehouse, retail outlet, depot, and operational facility where you have operational control must be represented in the underlying data, even if the CRP itself presents consolidated totals rather than a site-by-site breakdown.
Critically, the CRP must also be published on your organisation's website before the tender submission deadline. Procurement teams can and do check published CRPs against submitted tender documents and other publicly available information about your business. According to procurement data analysed by Tussell, approximately 12 percent of CRP-related bid failures in 2024 were attributed to inconsistencies between the published CRP and information available elsewhere about the supplier's operations. If your published CRP excludes sites that the contracting authority knows about through Companies House filings, your website, or other tender documents, this creates a credibility issue that could affect your bid evaluation or lead to outright disqualification from the procurement process.
Procurement evaluators follow structured assessment criteria when reviewing Carbon Reduction Plans, and understanding their approach helps you prepare a stronger submission. Evaluators are not carbon accounting experts, but they are experienced at checking compliance against structured templates. They verify that your CRP includes all required sections as defined by PPN 06/21, that your emissions data appears reasonable for your organisation's size and sector, and that your reduction targets are credible and time-bound. For multi-site organisations specifically, they look for evidence that the reported footprint covers the whole business, not just the head office or the site delivering the specific contract.
According to guidance from the Crown Commercial Service published in their procurement training materials, evaluators may cross-reference your CRP against your company profile, annual accounts, Companies House filings, or other tender documents submitted as part of the same bid. If your tender states you operate from five locations across the UK but your CRP reports total emissions of only 15 tonnes of CO2 equivalent, which is consistent with a single small office, this inconsistency will raise immediate questions. According to a 2024 survey of public sector procurement professionals conducted by the Chartered Institute of Procurement and Supply, 68 percent of evaluators said they routinely check whether CRP emissions figures are plausible for the stated organisation size. Some evaluators will treat obvious inconsistencies as a compliance failure; others will request clarification through the tender portal, which delays the process and weakens your competitive position.
The strongest multi-site CRPs include a brief description of the organisation's operational footprint, the number and types of sites included in the boundary, the consolidation approach used (typically operational control), and a clear statement confirming that the reported emissions cover all locations. According to analysis by the National Audit Office, contracting authorities are increasingly scrutinising the quality of CRPs rather than simply checking for their existence, particularly for high-value contracts. CarbonPass generates this narrative section automatically based on the locations you add to your account, ensuring your CRP tells a coherent story about your multi-site operations and how emissions have been consolidated across all locations.
Incomplete data is the single biggest challenge for multi-site organisations preparing their first Carbon Reduction Plan, but it is a solvable problem that should not prevent you from submitting a compliant CRP. Many multi-site organisations struggle because data quality varies enormously across their estate. Your head office may have detailed energy bills with monthly meter readings and comprehensive travel records, while a small regional office in a shared serviced building might have nothing beyond a total rent figure that bundles utilities into the service charge. According to research published by the Carbon Trust, approximately 40 percent of UK businesses with multiple sites report significant data gaps at one or more locations during their first year of carbon reporting.
The GHG Protocol Corporate Standard explicitly allows estimation methods where measured activity data is unavailable, provided you document your estimation approach and flag which data points are estimated rather than measured. For sites without utility bills, you can use floor-area-based energy benchmarks published by CIBSE, which provide typical consumption figures in kWh per square metre for different building types. For example, a typical air-conditioned office consumes approximately 120 kWh of electricity and 100 kWh of gas per square metre per year, while a naturally ventilated office uses around 75 kWh of electricity and 120 kWh of gas. For serviced offices, ask the building manager for an energy allocation based on your occupied floor area, or use the spend-based emission factors from DEFRA's conversion factor tables. The key is to document your estimation method clearly in your CRP narrative so you can justify it if questioned by procurement evaluators.
CarbonPass supports mixed data quality across sites within the same organisational account. You can enter measured kilowatt-hour data for locations where utility bills are available and use our built-in estimation tools for sites with incomplete records. The platform uses DEFRA's 2024 conversion factors, including the electricity factor of 0.20705 kgCO2e per kWh and the gas factor of 0.18293 kgCO2e per kWh, applied consistently whether the underlying consumption data is measured or estimated. The system flags which sites use estimated data and helps you build a data improvement plan for future reporting years, which strengthens your CRP narrative around continuous improvement. According to the GHG Protocol guidance on data quality, demonstrating a clear trajectory from estimated to measured data is viewed positively by both auditors and procurement evaluators.
Start data collection early and appoint clear responsibility at each location. The most common reason multi-site organisations fail to submit a compliant CRP is not the complexity of the calculations or the consolidation methodology, but simply the time needed to gather data from all locations before the tender deadline. Allow at least four to six weeks for site managers to collect and submit their data, especially if this is your first reporting year. According to a 2024 analysis of procurement timelines by Tussell, the average time between a government contract being advertised and the submission deadline is 30 to 45 days, which leaves very little margin if you have not already begun your carbon reporting process.
Appoint a named data contact at each location who is personally responsible for collecting and submitting the required information. This person does not need sustainability expertise or carbon accounting knowledge; they simply need access to utility bills, fuel card statements, and waste disposal invoices. Provide each site contact with a clear checklist of exactly what data is needed, the units required (kilowatt-hours not pounds for energy, litres not pounds for fuel), the 12-month reporting period, and a firm internal deadline that gives you time to review and consolidate before the tender submission date. CarbonPass's multi-site data collection workflow streamlines this by generating per-site data entry forms that guide each contact through exactly what information is needed and validate inputs as they are entered.
Use a single centralised platform for all sites rather than collecting data in separate spreadsheets, emails, or shared documents. According to research by the Carbon Trust, spreadsheet-based carbon accounting approaches introduce version control problems, inconsistent emission factor application, manual aggregation errors, and a lack of audit trail. Their analysis found that spreadsheet-based calculations have an average error rate of 12 to 18 percent, compared to less than 2 percent for purpose-built carbon accounting platforms. A dedicated tool like CarbonPass ensures consistent application of DEFRA emission factors across all locations, eliminates manual consolidation errors, and provides a complete audit trail that you can present to procurement teams if they request evidence of your calculation methodology. For organisations of the 5.5 million UK SMBs that bid for government contracts, investing in proper tooling pays for itself through reduced preparation time and stronger bid outcomes.
Understanding why multi-site CRPs fail helps you avoid the same mistakes in your own submission. The most frequent disqualification reason is submitting a CRP that clearly does not cover the full organisation. If your tender documents describe operations across multiple locations, multiple employee groups, or a national service delivery capability, but your CRP reports suspiciously low emissions consistent with a single small office, evaluators will notice the discrepancy immediately. According to procurement feedback published by the Crown Commercial Service in their 2024 annual review, incomplete organisational coverage is one of the top three reasons Carbon Reduction Plans are rejected, alongside failure to publish the CRP on the supplier's website and omission of required Scope 3 categories.
Other common issues that lead to disqualification or negative evaluation include failing to publish the CRP on your company website before the tender deadline, which is a mandatory requirement under PPN 06/21 and not merely a recommendation. Some organisations prepare an excellent CRP but forget to publish it, or publish it after the submission deadline, which technically renders the bid non-compliant. According to data from Crown Commercial Service, approximately 8 percent of CRP failures in 2024 were due to publication timing issues alone. Additional problems include presenting reduction targets that are not credible for your sector, using outdated emission factors from previous years, and failing to include the required Scope 3 categories such as business travel, employee commuting, and waste generated in operations.
The simplest way to avoid these issues is to use a purpose-built tool that enforces the correct CRP structure and ensures all mandatory elements are present before you can finalise the document. CarbonPass generates CRPs that include all required sections as specified by PPN 06/21, apply the correct DEFRA emission factors for your reporting year, and present data in the format procurement teams expect to see. For multi-site organisations, the Business plan handles consolidation automatically, applying consistent emission factors across all locations and presenting both consolidated and site-level data. The platform also includes a pre-submission checklist that verifies your CRP is complete, published, and ready for tender inclusion, reducing the risk of preventable disqualification from contracts that could be worth millions of pounds to your business.

Last updated: 8 April 2026Yes. PPN 06/21 requires the CRP to cover your entire organisational carbon footprint. You cannot exclude sites simply because they are small or have limited data. If a site falls within your organisational boundary, its emissions must be included - even if you need to use estimates for some data points.
New sites opened after your reporting period do not need to appear in the current CRP data, but you should mention them in your narrative and commit to including them in the next reporting year. Procurement evaluators want to see that you have a plan for capturing new sites going forward.
Home offices where employees work remotely should be captured under Scope 3 Category 7 (employee commuting and homeworking). You do not need to treat each home as a separate site, but the aggregate homeworking emissions should be estimated and included in your Scope 3 reporting.
The CRP does not require a site-by-site breakdown in the published document, but your underlying data must cover all sites. Most organisations present consolidated totals by scope and include a brief narrative explaining the types of sites included. CarbonPass generates the correct format automatically.
Remote workers are typically captured as an aggregate figure under Scope 3 using the EcoAct or BEIS homeworking emission factors. You calculate the number of remote working days across your workforce and apply a per-day emission factor. This does not require treating each home as a separate site.
Procurement teams may ask to see your underlying data, calculation methodology, or the tool used to generate the CRP. Having site-level data organised in a platform like CarbonPass means you can provide evidence quickly. Some contracting authorities also check that your CRP is published on your website as required.
