How the Iran War Will Affect UK Mortgages, Energy Bills and Jobs

How the Iran War Will Affect UK Mortgages, Energy Bills and Jobs

The Bank of England has set out in unusual detail how the conflict in the Middle East is expected to ripple through UK household finances in 2026. Although the central bank held interest rates steady at its most recent meeting, its rate-setting committee's published report signals that higher mortgage costs, rising energy bills and a weakening jobs market are all likely outcomes — with the scale depending heavily on how the war develops.

This post draws on the Bank of England's published analysis, as reported by BBC News on 1 May 2026, to explain what UK households should realistically expect.

What's happening

The Bank of England's Monetary Policy Committee kept the base rate on hold but made clear that rate rises could follow later in 2026. The committee assessed a range of scenarios tied to the severity and duration of the Iran war.

In the scenario the Bank governor placed most weight on — where energy prices fall slowly — one or two rate rises are considered likely. In the most adverse scenario, where oil stays above $120 a barrel for the rest of the year and inflation climbs above 6% in early 2027, as many as six rate rises could occur, potentially pushing the base rate to 5.5%.

At the same time, the Bank confirmed that domestic energy bills will rise this summer. For a household using a typical amount of gas and electricity, the current annual bill stands at £1,641 under the Ofgem price cap. The Bank expects this to rise to close to £1,900 in July 2026 and remain at that level through the rest of the year.

The Ofgem price cap is the maximum unit rate that energy suppliers in England, Scotland and Wales can charge households. In plain terms, it sets the ceiling on what most people on standard variable tariffs pay for gas and electricity each quarter.

Why it matters

Energy prices do not just affect energy bills. When oil and gas costs rise, the price of food, transport and manufactured goods tends to follow. The Bank expects food price inflation to reach 4.6% by September 2026 and potentially go higher after that.

Higher inflation, in turn, puts pressure on the Bank to raise interest rates — which increases the cost of borrowing on mortgages, credit cards and loans, while also improving returns on savings accounts.

The Bank also warned that households may respond to economic uncertainty by saving more and spending less. If consumer demand weakens, businesses are more likely to reduce hiring or cut jobs, particularly if they are already facing higher energy costs themselves. UK unemployment has been rising steadily over the past year, and the Bank cautioned it could rise further.

Who is affected

Mortgage holders are among the most directly exposed. More than seven million UK homeowners — 87% of all mortgage holders — are on fixed-rate deals. A fixed-rate mortgage locks in an interest rate until the deal expires, typically after two or five years. When that deal ends and a new one is chosen, the new rate reflects current market conditions.

The Bank estimates that average monthly payments for those moving on to a new deal over the next three years will rise by approximately £80. Around 53% of mortgage holders are expected to see payments increase. However, about 25% of those who fixed at higher rates in recent years may actually see payments fall, even with recent rate increases factored in.

Households on standard variable energy tariffs will see bills rise from July. Those on prepayment meters can reduce exposure during warmer months by using less energy, but the Bank notes that if prices remain high in winter, these households will face larger cost increases.

Households on fixed energy tariffs — currently around 40% of UK homes, a higher proportion than the roughly 25% who had fixed tariffs when prices surged after Russia's invasion of Ukraine in 2022 — are protected until their contracts end.

Lower-income households face the greatest overall pressure. Food and energy are essentials that take up a larger share of lower incomes. The Bank noted that, compared with 2022, a greater proportion of lower-income households now have less than two weeks of income saved, leaving less of a financial buffer.

What to do next

• Check when your fixed-rate mortgage deal expires. If it ends in the next 12 months, it is worth understanding what rates are currently available so you are not caught off guard.
• Find out whether you are on a fixed or variable energy tariff. If you are on a standard variable tariff, you will be subject to the Ofgem price cap changes from July. If you are on a fixed tariff, check when it expires.
• Consider your energy usage ahead of winter. The Bank specifically noted that households on prepayment meters can reduce consumption during summer months to manage costs before winter, when bills are typically higher.
• Review your savings buffer. The Bank's analysis highlights that lower-income households with limited savings are least able to absorb rising costs. Even a small emergency fund reduces reliance on borrowing.
• Compare energy tariffs before your current deal ends. If your fixed energy contract is due to expire, comparing available tariffs before it does can help you avoid automatically rolling on to a higher variable rate. You can use Taupia to compare household energy tariffs and check whether switching could reduce your bill.

The Bank of England's projections carry significant uncertainty — the outcome depends on how the conflict develops, how long energy prices stay elevated, and how quickly the wider economy adjusts. The figures cited here reflect the Bank's central and adverse scenarios as of early May 2026, not guaranteed outcomes.
