What Is Nation Data in EPR Reporting?

When you submit your packaging data to DEFRA via the RPD portal, you must break down your packaging volumes by the UK nation where the packaging is placed on the market. This means reporting what proportion of your packaging ends up in:

England
Scotland
Wales
Northern Ireland

Each line of your RPD submission must include this geographical breakdown. The nation split applies to the packaging weight — so if you report 50 tonnes of plastic packaging, you must estimate how many tonnes went to each nation.

This is one of the more complex aspects of EPR reporting, particularly for businesses that sell across the entire UK without tracking delivery destinations at a granular level.

Why DEFRA Requires Nation-Level Data

Each UK nation has its own environmental regulator and waste management infrastructure:

England: Environment Agency
Scotland: SEPA (Scottish Environment Protection Agency)
Wales: NRW (Natural Resources Wales)
Northern Ireland: NIEA (Northern Ireland Environment Agency)

EPR fees collected by PackUK are distributed to local authorities across the UK to fund packaging waste collection and recycling. The nation data ensures that fees are allocated proportionally to where the packaging waste actually arises. Without this data, England would receive a disproportionate share simply due to population size, which would disadvantage the devolved nations.

Additionally, each nation may have slightly different recycling targets, collection approaches, and policy priorities. Nation-level data allows regulators to track progress against their specific targets.

The Four UK Nations and Their Regulators

England

Regulated by the Environment Agency. England accounts for approximately 84% of the UK population and typically the largest share of most businesses’ packaging distribution. The Environment Agency leads enforcement for most obligated producers.

Scotland

Regulated by SEPA. Scotland represents approximately 8% of the UK population. Scotland has introduced separate policies around deposit return schemes and has distinct recycling targets. If you sell into Scotland, you must account for this in your nation data.

Wales

Regulated by NRW (Natural Resources Wales). Wales accounts for approximately 5% of the UK population. Wales has been a leader in recycling policy, with some of the highest recycling rates in the UK. Some packaging regulations may differ slightly from England.

Northern Ireland

Regulated by NIEA (Northern Ireland Environment Agency). Northern Ireland represents approximately 3% of the UK population. Cross-border trade with the Republic of Ireland creates additional complexity for some businesses.

How to Estimate Your Nation Data Split

Most businesses do not track every delivery to a specific UK nation. Instead, DEFRA accepts reasonable estimates based on available data. Here are three approaches, from most to least accurate:

Method 1: Sales Data Analysis (Most Accurate)

If your order management or e-commerce system records delivery postcodes, you can calculate your actual nation split. UK postcodes map to nations as follows:

England: Postcodes starting with most letter combinations (e.g., B, CB, CM, CO, etc.)
Scotland: AB, DD, DG, EH, FK, G, HS, IV, KA, KW, KY, ML, PA, PH, TD, ZE
Wales: CF, LD, LL, NP, SA, SY (some SY postcodes are in England)
Northern Ireland: BT

This method gives the most accurate split and is the one DEFRA prefers. If you sell direct to consumers online, your order data almost certainly contains this information.

Method 2: Revenue-Based Estimation

If you sell through wholesale channels and know which retailers you supply, estimate the proportion of sales going to stores in each nation. Major retailer chains can often provide a breakdown of store locations by nation.

Method 3: Population Proportional (Fallback)

If you have no better data, you can use the UK population split as a proxy:

Nation	Population Share
England	84%
Scotland	8%
Wales	5%
Northern Ireland	3%

This is the least accurate method and should only be used as a last resort. DEFRA may query submissions that rely solely on population proportional splits if you sell through channels where better data is available.

Methods for Calculating Nation Distribution

For Direct-to-Consumer (DTC) Businesses

Extract delivery postcode data from your e-commerce platform or order management system. Most platforms (Shopify, WooCommerce, Magento) allow you to export order data including postcodes. Map postcodes to nations using the prefix rules above.

Example calculation:

Total orders: 50,000

England deliveries: 42,500 (85%)
Scotland deliveries: 3,500 (7%)
Wales deliveries: 2,500 (5%)
Northern Ireland deliveries: 1,500 (3%)

Apply these percentages to your total packaging weight for each material type.

For Wholesale and B2B Businesses

If you supply retailers or distributors, estimate based on where your customers’ stores or warehouses are located. A regional retailer operating only in the Midlands would be 100% England. A national supermarket chain would distribute across all four nations.

For Importers

If you import goods into the UK, the nation data relates to where those goods are eventually sold or distributed within the UK — not where they enter the country. A container of goods landing at Felixstowe but distributed to retailers across the UK must be split across all four nations.

Common Nation Data Mistakes

Using the Same Split for All Materials

Your nation distribution may differ between product lines. If you sell wine primarily to Scottish hotels and cardboard packaging to English retailers, those two product lines will have different nation splits. Use product or channel-specific data where available.

Ignoring Northern Ireland

Some businesses report zero for Northern Ireland because they believe they do not sell there. If your products are available through national retail chains or online, some will inevitably reach Northern Ireland. Even a small percentage should be reported rather than zero.

Not Updating Splits Over Time

Your nation distribution may change as your business grows or as you enter new retail channels. Review your nation data at least annually and update your estimates to reflect current trading patterns.

Rounding Errors

Your nation percentages must sum to 100% for each packaging line. A common error is rounding each nation independently, resulting in a total of 99% or 101%. Adjust your rounding to ensure the total is exactly 100%.

Simplifying Nation Data with Our Platform

Nation data reporting is one of the most tedious aspects of EPR compliance. Our platform simplifies it:

Set your nation split once — enter your estimated distribution by nation, and we apply it automatically to all packaging entries
Override per product line — if different products have different distributions, you can set specific splits
Auto-calculation — the platform calculates the tonnage per nation based on your total weights and distribution percentages
DEFRA-ready exports — your RPD report includes the correct nation data columns formatted exactly as DEFRA expects
