What contractors as UK homeowners need to know to shelter from the Middle East conflict.
At the precise moment that contractors looking to buy a property or move off a mortgage rate were daring to feel optimistic, the US-Israel war with Iran sent shockwaves through UK financial markets.
And those reverberations for such homeowners and homebuyers continue today.
Here, exclusively for ContractorUK, I will explain what’s happened to UK mortgage rates since the Iran war started, why it matters for mortgages, and what steps we recommend homeowners take over the next six months, writes John Yerou, founder of specialist mortgage broker Freelancer Financials.
Key takeaways
- A repricing of mortgage deals is underway due to the Iran war, partly explaining why one in five recent mortgage deals is no longer available.
- The March 2nd closure of the Strait of Hormuz signals higher inflation, and less likelihood that UK interest rates will be cut on April 30th 2026.
- The continued closure of the Strait of Hormuz is part of a ‘worst-case’ scenario (outlined by Oxford Economics/ING) in which mortgage rates hit 6%.
- Average mortgage rates for a 2-year fixed rate product are already up to 5.56%, compared with 3.51% before the war started on Feb 28th.
- Contractors coming off a mortgage in a few months must act now, use a ‘lock-in’ service, and consult a whole-of-market broker with ‘live’ knowledge.
When did the Iran war start?
The US-Israeli military action against Iran began on February 28th 2026.
So, following six Bank of England rate cuts since August 2024, and a tentative recovery in UK house prices, the US-Israel military action against Iran has reversed months of progress in as little as four weeks.
Swap rates – the key mechanism through which global events translate into your mortgage costs – surged from their lowest level since mid-2022 in the week before the war in the Gulf, to multi-month highs within days of the first strikes.
As a result, lenders have repriced upwards across the board, and as of today (Day 31 of the conflict), 20% of mortgage products have been withdrawn from the market.
How the Iran war has already hit UK mortgage rates – and why
The strategic Strait of Hormuz, announced by Iran as closed on March 2nd 2026, handles 20% of global oil supplies.
Its closure triggered the largest energy supply disruption in recorded history, resulting in two key blows for British homeowners — Brent crude surging past $100 per barrel, and QatarEnergy declaring ‘force majeure’ after Iranian drone strikes on its gas facilities.
What does the closure of the Strait of Hormuz mean for the UK economy?
For the UK, which is a major energy importer, that closure and its two key consequences translate, directly, into:
- Higher inflation
- A less likely Bank of England interest rate cut
- Rising swap rates, and
- More expensive mortgages.
How is the Iran war affecting the gilt market?
Meanwhile, the gilt market has reacted with equal force to the closure of the Strait of Hormuz.
(Editor’s Note: Media reports based on US claims suggest Iran has agreed to let 20 ships through the Strait of Hormuz, but generally, Iran has reportedly denied talks with the US).
Did UK mortgage lenders have a choice about repricing rates?
The 10-year gilt yield has now hit 5.00%. That represents its highest since the 2008 financial crisis.
And two-year gilt yields rose over 40 basis points in a single week — and since swap rates track gilts closely, mortgage lenders had little choice but to reprice.
How the US-Iran war has pushed up mortgage rates
| Type of mortgage product | Pre-war (27 Feb) | Now (30 March 2026) |
|---|---|---|
| Avg 2-yr fixed rate | 4.82% | 5.56% |
| Avg 5-yr fixed rate | 4.95% | 5.54% |
| Lowest rate on market | 3.51% | 4.55% |
| 10-yr gilt yield | ~4.30% | 4.93% |

How are UK mortgage lenders responding to the Iran war?
Around one in five residential mortgage products has been withdrawn from the UK mortgage market since the conflict in the Gulf began.
HSBC, Nationwide, Coventry, Principality, Skipton, and TSB (a 50-basis-point blanket hike!), plus other lenders, have all repriced. And in some cases, repricing has happened more than once.
When was the UK mortgage market last volatile?
Over at Moneyfacts, Adam French described it as some of the most turbulent conditions on the mortgage market since the 2022 mini-Budget.
Positively, it’s been noted that the housing market was in comparatively robust shape going in, with a record product count before the crisis.
The Bank of England (BoE) held UK interest rates at 3.75% on March 19th 2026 — and that was a meeting which markets had expected to deliver a cut to the rate a few weeks earlier.
Amid the Iran war, what’s the six-month outlook for UK mortgage rates?
Everything, including the six-month outlook for UK mortgage rates, hinges on two variables:
- how long the conflict continues, and
- whether the Strait of Hormuz reopens.
Oxford Economics and ING have set out three broad scenarios (best-case, base-case, worst-case), which we recommend contractors with mortgage concerns keep at the front of their minds.
What are the predictions of the Iran war’s economic impact?
- Best case: Oil returns to $70–75 by May. BoE cuts interest rates in Q2/Q3 2026. Average 2-year fixed-rate mortgage retreats toward 4.5–4.75%.
- Base case: Oil stays $85–100 through Q2. BoE holds all year. Mortgage rates stabilise around 5.0–5.5%. Limited mortgage product choice persists.
- Worst case: Strait of Hormuz remains blocked, with structural damage to Qatari LNG (liquefied natural gas) taking months to repair (following missiles that caused “extensive damage” on March 19th). Oil stays above $100 per barrel. The BoE potentially raises rates. Two-year fixed rate mortgages push towards 6%.
How long might energy prices take to normalise?
Crucially, even a ceasefire may not quickly resolve energy prices.
Damage to production infrastructure — particularly Qatari LNG (which is used globally for cooking, heating homes and generating electricity) — means supply restoration could take months, regardless of political developments.
The UK’s NIESR (National Institute of Economic and Social Research) has warned that sustained high energy prices could force the Bank to raise rates above 4%.
And keep in mind, NIESR’s warning was on March 4th, when the volatility was only just starting.
What if my mortgage is ending soon, as the Iran war continues?
We believe it’s prudent to now issue some urgent advice.
If you’re a contractor whose mortgage is ending in the next three to six months, we’d strongly advise you to act now.
Why? Well:
A number of lenders let you lock in a new rate up to six months before your deal ends, without early repayment charges. If mortgage rates fall before completion, you can often switch to the lower rate. Waiting carries real risk in the current environment.
Who are the three key users of a ‘lock-in’ mortgage rate service?
The users of something that many contractors who we support with mortgages have told us that they find very helpful — our rate monitoring service — tend to be in three situations:
- On a tracker or variable rate: Model the impact of a potential 0.25–0.5% base rate rise on your monthly payments now (if you haven’t used them before, our free calculators are here)
- Need to remortgage: Two-year fixes offer optionality if rates fall, whereas five-year fixed mortgages give certainty but lock in higher costs for longer.
- First-time buyer: Buyer demand for UK residential properties has softened, particularly in London and the South East, which may afford you some helpful negotiating room on price.
What role are lenders playing in the mortgage market?
It’s true that lenders have been withdrawing mortgage deals and raising rates because of the March 2nd closure of the Strait of Hormuz. But it’s also true that home loans have been disappearing because lenders are struggling with volume. And lenders themselves are now trying to slow the market down.
So far, since the Iran war began, lenders have been pricing home loans based on what they perceive the risk to be (informed by the cost of future funds).
Where are UK interest rates heading in Q2 2026?
For many of us, ‘future costs’ depend on the BoE’s next interest rate meeting on April 30th 2026. My feeling, at this stage, is that the Bank of England will do everything possible to hold the base rate at 3.75%.
If Iran and the US reach an agreement before April 30th, then the BoE Monetary Policy Committee (MPC) will likely vote to leave the base rate where it is currently. If the Iran war is still underway by then, the bank might have no choice but to raise interest rates by 0.25%.
The takeaway
In the fast-changing situation of the US-Iran war, UK mortgage-holders, including contractors, should seek advice from an independent, whole-of-market broker like Freelancer Financials. Contractors should not take on the added risk of ‘going direct’ to a lender at an already incredibly risky time.
The mortgage rates and product landscapes are shifting daily, and the best deal for your loan-to-value and unique contractor circumstances requires ‘live’ market knowledge.
