OBR forecasts reveal the pressure of higher energy prices, weak household income growth and the rising cost of government debt.
The latest forecasts from the Office for Budget Responsibility (OBR) paint a mixed picture of the British economy. Growth has proved more resilient than expected this year, but the outlook remains uncertain and the cost of dealing with international shocks is eating into the Government's financial flexibility.
For households and businesses, the message is less reassuring than the headline growth figures might suggest. The economy is expanding, but that does not necessarily mean people will feel better off.
Growth today, slower progress tomorrow
The OBR has raised its forecast for UK economic growth in 2026 to 1.2%, up from 1.1% in its March forecast. That is a modest improvement, and the UK has recorded joint-fastest growth among the G7 major economies during the first half of the year.
However, the forecast for 2027 is less encouraging. Growth is expected to slow to just 1.0% before recovering to 1.6% in 2028 and 1.8% in 2029. Growth is then forecast at 1.7% in 2030 and 1.6% in 2031.
These are projections rather than promises. They depend on assumptions about energy prices, productivity, employment, interest rates and the international economy.
The figures suggest Britain is unlikely to enjoy a dramatic economic recovery in the near future. Even if the forecasts prove accurate, growth of around 1% or 2% a year will not quickly resolve the pressures facing public services, household budgets and businesses.
The international energy shock comes at a price
The conflict in the Middle East has complicated the Chancellor's task. Higher oil and gas prices increase costs for households and businesses while adding to inflationary pressures across the economy.
The consequences extend well beyond filling a car or heating a home. Transport, food production, manufacturing, distribution and many service businesses depend directly or indirectly on energy.
For the Government, the shock creates a double problem. It must consider assistance for households and businesses while paying more to service the national debt.
The Budget documents say the OBR expects the Government to pay an average of £14 billion a year more in debt interest than anticipated in the spring. That is money which cannot also be spent on hospitals, schools, housing, defence or transport.
The Chancellor has therefore chosen to use some of the financial room built up in the previous forecast to absorb the additional costs rather than immediately impose broad-based tax increases.
That may be a reasonable response to an unexpected crisis. But it leaves less protection against whatever comes next.
How much room is left in the Treasury's finances?
One of the most important figures in the Budget is the Government's fiscal headroom.
This is the margin by which the Government expects to meet its self-imposed fiscal rules. It is not a spare pot of cash sitting in a bank account. It is a forecast-based cushion which can disappear if economic conditions deteriorate.
The Government's headroom against its day-to-day budget rule is now forecast at £15 billion in 2029-30, rising to £22 billion in 2030-31. The equivalent figure in the spring forecast was £23.6 billion for the earlier target year.
That reduction illustrates how quickly an apparently manageable financial position can change when borrowing costs rise.
The Government expects borrowing to fall over the forecast period, reaching 1.8% of GDP by 2031-32. It also forecasts that debt will be lower at the end of the period than at the beginning.
But the forecasts depend on the economy performing broadly as expected. A renewed rise in energy prices, weaker growth, disappointing tax receipts or higher interest rates could make the arithmetic more difficult.
The Chancellor has retained a financial buffer, but it is thinner than before. That limits the scope for further large-scale assistance if another emergency arrives.
Household incomes remain under pressure
Economic growth does not automatically translate into higher living standards for everyone.
The OBR forecasts real household disposable income per person falling by 0.8% in 2026, followed by growth of just 0.1% in 2027. It expects more substantial annual increases in subsequent years, although these remain forecasts rather than guaranteed outcomes.
That is an important distinction. Household disposable income measures what people have available after taxes and benefits, adjusted for inflation. It helps explain why the public can feel worse off even when the economy is technically growing.
Families have already had to absorb years of higher living costs. Mortgage payments, rent, food, insurance, energy and transport can leave little room for discretionary spending.
When households become uncertain about their finances, they may postpone replacing a car, eating out, visiting the pub or making other purchases. Individually, those decisions may be sensible. Collectively, they can weaken demand for businesses that depend on consumer spending.
There is a potential vicious circle: households become cautious, businesses see weaker demand, investment and recruitment suffer, and economic growth slows further.
Jobs and productivity are part of the problem
The OBR expects unemployment to rise from 5.0% in 2026 to 5.1% in 2027 before falling in subsequent years.
That is not a forecast of a dramatic jobs collapse, but it indicates that the labour market may remain difficult, particularly for younger people and those trying to enter employment.
Productivity is equally important. Britain needs to produce more economic value from the hours people work if it is to achieve sustained improvements in wages and living standards.
The forecast anticipates a gradual improvement in productivity growth over the coming years. Yet this remains an area of uncertainty. Artificial intelligence and other new technologies could help businesses become more productive, but the benefits will depend on how widely and effectively they are adopted.
Investment is encouraging, but companies will be reluctant to commit money if they cannot see sufficient demand or if borrowing costs remain high.
What does this mean for Scotland and Caithness?
National forecasts rarely capture the full differences between regions.
For Caithness and the wider Highlands, the important questions concern employment, investment, transport, energy costs and the strength of local demand.
Businesses operating in remote areas can face additional transport and distribution costs. Households without access to the gas grid may depend on heating oil or other fuels whose prices do not necessarily move in line with domestic electricity tariffs.
Higher costs can also affect contractors, small retailers, hospitality businesses and public-service suppliers. If councils and other public bodies face tighter budgets, local businesses may find that contracts are harder to win or that pressure to contain costs increases.
There are opportunities too. Energy projects, infrastructure investment, engineering, technology and the development of new industries could provide employment and strengthen the local economy.
But national growth forecasts will mean little to communities that do not attract investment or secure lasting jobs. The challenge is to turn economic activity into opportunities that remain in the area rather than relying on temporary construction work alone.
Forecasts are not facts about the future
The OBR provides an independent assessment of the Government's economic and fiscal plans. Its forecasts are valuable because they expose the assumptions on which political promises depend.
However, a five-year forecast is not a precise prediction of what will happen. Changes in international events, energy prices, interest rates, wages, employment and productivity can alter the outcome considerably.
The figures should therefore be read as a guide to the risks and likely direction of travel, not as a set of guaranteed results.
The central message is that Britain has avoided a more immediate economic setback, but the underlying challenges remain. Growth is modest, household income is under pressure and the cost of government borrowing has risen.
The Government has chosen to use some of its financial cushion to soften the effects of the latest crisis. That may help in the short term, but it leaves a difficult question for the years ahead.
If another shock arrives before growth strengthens and the public finances improve, where will the money come from?
That is the question behind the forecasts, and one which neither a Budget speech nor a set of economic projections can answer with certainty.
