Most small and medium-sized businesses in the UK are making high-stakes decisions — hiring, repricing services, expanding into new regions — on instinct and anecdote. That is understandable. Commissioning bespoke market research is expensive, and the idea of trawling through government datasets feels like something reserved for economists with too much time on their hands. But ONS data for business decisions in the UK is far more accessible than its reputation suggests, and the founders and managers who have learnt to use it are quietly gaining a genuine edge.
The Office for National Statistics publishes an enormous volume of free, credible data covering wage growth, sector output, regional employment, inflation by category, and much more. The challenge is not access; it is knowing which datasets are actually useful and how to apply them to real commercial questions. This walkthrough covers exactly that.
Why ONS Data Is Worth Your Attention
Before getting into specific datasets, it is worth being clear about what ONS data actually is. The ONS is the UK’s national statistics authority. Its data feeds into government policy, the Bank of England’s decisions, and major corporate strategy. When a large enterprise benchmarks its hiring budget against national wage trends, this is largely where that benchmarking starts.
For a business with no dedicated research function, using ONS data means accessing the same primary source that professional analysts use — at no cost. That is not a trivial point. A mid-market consultancy might charge thousands for a sector briefing that draws heavily on ONS publications. You can get to the same underlying numbers yourself, with a little guidance on where to look.
Wage Growth Data: Setting Salaries That Are Competitive and Sustainable
One of the most directly useful ONS datasets for hiring decisions is the Annual Survey of Hours and Earnings, commonly known as ASHE. It breaks down median and mean wages by industry sector, occupation, region, and employment type. If you are hiring a marketing manager in Manchester or a software developer in Bristol, ASHE gives you a solid benchmark rather than relying on salary survey sites that may not reflect local conditions accurately.
The key figures to focus on are the median gross weekly earnings by occupation code and region. If your current pay offer sits significantly below the median for your sector, you will lose candidates to competitors even if your culture and benefits are strong. Equally, if the data shows that wage growth in your sector has outpaced general inflation — which in several professional services categories it has over the past two years — you can pre-empt future retention problems by adjusting pay structures now rather than reactively.
You can access ASHE data directly on the ONS earnings and working hours pages, where the datasets are available in Excel format and updated annually.
Sector Output Data: Reading the Direction of Your Market
The ONS publishes GDP output figures broken down by industry sector, using the UK Standard Industrial Classification system. The monthly GDP by output approach data shows, in practical terms, whether your sector’s output is growing, contracting, or flattening. This matters for pricing and investment timing.
If you operate in professional and business services, for instance, and the data shows that sector output has grown for five consecutive quarters, that is a reasonable signal that clients are spending. Raising prices or launching a higher-tier service offering into a growing market carries less risk than doing the same during a period of contraction. Conversely, if output in your sector is declining, that is useful intelligence when deciding whether to push forward with a new hire or hold the position open for another quarter.
The same data can be used comparatively. If your sector is shrinking whilst adjacent sectors are growing, that might prompt you to consider whether your service offering could be repositioned to serve those adjacent markets. That is strategic thinking that would cost a considerable sum from a management consultancy, and the underlying data is free.
Regional Employment Figures: Informing Expansion With Actual Evidence
Expanding into a new region — opening a second office, hiring a regional sales lead, targeting a new city — is a significant commitment. The ONS’s regional labour market statistics provide employment rates, unemployment rates, and economic inactivity figures broken down to the local authority level. Combined with the Subregional Productivity publication, which covers output per worker by area, you can build a meaningful picture of which regions have a strong working-age population, competitive labour costs, and growing local economies.
For example, a professional services firm considering whether to establish a presence in Leeds versus Sheffield could use ONS regional data to compare employment rates, sector composition, and wage levels in both areas. That is not a comprehensive location assessment, but it provides a data-backed starting point that significantly narrows down the decision.
Regional population projections, also published by the ONS, are useful if your expansion is consumer-facing. Understanding which cities are projected to see strong population growth over the next decade is relevant if you are thinking about where to invest marketing spend or open a new client-facing operation.
Inflation and Price Data: Getting Your Pricing Strategy Right
Beyond the headline Consumer Prices Index figure, the ONS publishes detailed CPI component data broken down by category. This is more useful for business pricing than most people realise. If your cost base is heavily weighted towards energy, transport, or specific categories of professional services, you can track how inflation in those specific components is moving rather than relying on the headline figure, which averages across a wide basket.
Producers Price Index data, also from the ONS, tracks the prices manufacturers pay for inputs and the prices they charge for outputs. For any business with a physical product element or supply chain, this data shows cost pressures upstream before they fully feed through to your own costs, giving you lead time to adjust contracts, renegotiate supplier terms, or build in price increase clauses.
How to Access and Work With ONS Datasets Practically
The ONS website has improved considerably in terms of usability. The main search function is functional, and the data pages now include clearer signposting to the relevant Excel files. Most datasets are published in tabular format that can be opened directly in Excel or imported into Google Sheets. You do not need specialist software.
A practical approach for a business without a research team is to identify three or four datasets that are directly relevant to your current business priorities — typically ASHE for hiring, sector output for market direction, and regional labour market statistics if expansion is on the agenda. Download the latest release, pick out the two or three most relevant figures, and add a quarterly review to your calendar. You are not trying to become a statistician; you are building a habit of grounding key decisions in evidence rather than assumption.
It is also worth bookmarking the ONS’s Business Insights and Conditions Survey, which tracks real-time business conditions across sectors and is updated frequently. It acts as a useful pulse-check between the larger annual publications.
A Few Caveats Worth Knowing
ONS datasets describe aggregates and averages. They are excellent for context and directional signals, but they do not replace direct customer research, competitor intelligence, or sector-specific knowledge. A region might have strong employment figures at the national level whilst your specific niche within it is overserved. Use ONS data as a layer of evidence, not as the sole basis for a decision.
Datasets also have publication lags. ASHE, for instance, reflects the previous tax year’s earnings. For fast-moving markets, supplement ONS data with real-time signals from job posting volumes, industry body reports, or your own customer conversations. The combination of macro data and ground-level intelligence is considerably more powerful than either source alone.
ONS data for business decisions in the UK is one of the most underused free resources available to founders and managers. The businesses that treat it seriously are, quietly, making better calls on headcount, pricing, and growth strategy. That is worth a few hours of your time to explore.
Frequently Asked Questions
What ONS datasets are most useful for small business decisions in the UK?
The Annual Survey of Hours and Earnings (ASHE) is excellent for salary benchmarking, whilst GDP by output broken down by sector helps with market direction. Regional labour market statistics are particularly valuable if you are considering geographic expansion or hiring in a new area.
Is ONS data free to access and use for commercial purposes?
Yes. All ONS publications are free to access on ons.gov.uk and are released under the Open Government Licence, which permits commercial use. You do not need to register or pay for access to any of the core economic datasets.
How often is ONS economic data updated?
It varies by dataset. Monthly GDP estimates are published roughly six weeks after the reference month, whilst ASHE is published annually, typically in the autumn covering the previous tax year. The Business Insights and Conditions Survey is updated more frequently and is useful for near-real-time signals.
How do I find wage data by region and sector on the ONS website?
Search for ‘ASHE’ on ons.gov.uk to find the Annual Survey of Hours and Earnings. The data is broken down by occupation code, industry sector, region, and employment type. The Excel files contain separate tabs for different geographies, including regional and local authority breakdowns.
