. The performance exceeded expectations given the challenging global backdrop of rising energy costs and geopolitical tensions.

Computer Programming and AI-Related Activities Drive Services Sector

The services sector emerged as the primary engine of third quarter growth, expanding 0.9% as AI-related activities and cloud computing demand surged across Britain's economy2

2

. Computer programming, consultancy and related activities grew an impressive 4.4%, helping lift the broader information and communication sector by 2.1%2

2

. The Office for National Statistics noted that computer programming and consultancy had been "the largest driver of GDP growth across 2026, with evidence that many of the businesses reporting the largest increases in turnover are involved in activities related to artificial intelligence and cloud computing"2

2

. Ruth Gregory, deputy chief UK economist at Capital Economics, observed that "growth was unusually concentrated in AI-related sectors"1

Manufacturing Sector Benefits from AI Hardware Demand

Manufacturing output grew 0.9% in the three months to September, led by a substantial 4.6% rise in production of computer, electronic and optical products2

2

. Sarah Coles, head of personal finance at AJ Bell, directly linked this manufacturing strength to AI demand, stating "it's another area where growth is underpinned by demand for AI"2

2

. While production output overall edged up just 0.1% and construction fell 0.7%, the AI-driven segments demonstrated remarkable resilience2

2

. Coles added that AI's gradual adoption already appears to be helping businesses in administrative and support services throughout the UK economy2

Bank of England Raises Growth Forecasts on AI-Driven Business Investment

The Bank of England last week lifted its growth forecasts for the UK economy to 1.6% for 2026 and 1.3% for 2027, up from 1.1% for both years projected in July2

2

. The central bank specifically cited strength in business investment linked to AI-related demand as a key factor behind the upgraded projections1

1

. These revised growth forecasts came as the Bank raised its benchmark interest rate by a quarter percentage point to 4%, marking the first increase since August 20232

2

. Gregory noted that "the latest monthly data suggests the economy is entering into Q4 with more momentum than we expected"1

Energy Pressures and Inflation Risks Loom Despite Strong Performance

Despite the positive UK economic growth figures, significant headwinds remain. UK inflation reached 3.5% in September, driven partly by higher household energy bills and motor fuel prices stemming from the US-Iran war2

2

. The Bank of England expects inflation to peak at 4.9% in the second quarter of next year in its central forecast1

1

. In a worst-case scenario where oil prices soar beyond $100 a barrel, the bank warned UK inflation could hit 6.2% in the third quarter of next year1

1

. Millions of Britons face rising energy bills from the start of 2027, even with Labour government assistance announced in last month's budget1

1

. Kit Rees, investment strategist at Quilter, cautioned that "the economy continues to show resilience but there are fears it will lose momentum just as energy-driven inflation is keeping pressure on interest rates"1

1

. Higher employment costs, rising energy prices and pressure on household budgets are likely to weigh on economic growth into 20272
