WGA vs OBR vs National Accounts: What’s the Difference?

20th June 2026

The UK publishes several major financial reports, and it’s easy to confuse them.
Here’s a clear comparison of the three most important ones.

1. Whole of Government Accounts (WGA)
What it is:
A commercial‑style set of accounts covering the entire public sector.

What it shows:

Assets

Liabilities

Long‑term obligations

Consolidated spending

Strength:
Most complete picture of the state’s finances.

Weakness:
Published very late and currently has a disclaimed audit opinion.

2. Office for Budget Responsibility (OBR) Fiscal Forecasts
What it is:
Independent forecasts of the UK’s public finances.

What it shows:

Future tax revenues

Future spending

Debt and deficit projections

Economic assumptions (growth, inflation, interest rates)

Strength:
Forward‑looking and essential for budget planning.

Weakness:
Not an audited account — it’s a forecast, not a statement of fact.

3. National Accounts (ONS Public Sector Finances)
What it is:
The official statistical measure of government finances, used internationally.

What it shows:

Deficit

Debt

Borrowing

GDP‑aligned measures

Strength:
Timely, internationally comparable, used for fiscal rules.

Weakness:
Does not include long‑term liabilities like pensions.

How They Fit Together
Think of them like this:

National Accounts = the monthly snapshot

OBR Forecasts = the future projection

WGA = the long‑term X‑ray

Together, they give a full picture — but each has blind spots.
