Stamp duty uncertainty is keeping the UK mortgage market in a holding pattern — should contractors wait?

What happened to stamp duty in April 2026

The temporary stamp duty relief that had been in place for first-time buyers and standard purchasers ended in April 2026. For first-time buyers, the nil-rate threshold returned to £300,000 (from the temporary £425,000), and for standard purchasers, the nil-rate band reverted to £125,000 (from £250,000). The effect on transaction costs was immediate and significant. A contractor buying a £291,000 property as a non-first-time buyer now faces a stamp duty liability of approximately £4,550 — a cost that did not exist for buyers who completed before April 2025.

Parliamentary discussions about further Stamp Duty Land Tax reform have continued since the reversion, with various proposals in circulation — but no confirmed date, structure, or scope for any changes. The market has been left in a position where buyers know the current rates are higher than they were, sense that reform might be coming, but have no confirmed timeline to plan around. This is the classic condition for market paralysis: the expected change is significant enough to be worth waiting for, but uncertain enough that waiting is itself a risk.

The cost of waiting for stamp duty reform

The paralysis logic looks like this: if reform reduces stamp duty on a £291,000 purchase by £4,550, waiting could save £4,550. That logic only holds if property prices do not rise in the interim. At 3.8% annual growth — the current Land Registry figure — a £291,000 property will cost £302,000 in 12 months. The price increase of £11,000 dwarfs the potential stamp duty saving of £4,550. The buyer who waited for reform has paid £6,450 more than they would have paid by acting now, even after accounting for the full saving if reform comes.

That calculation gets worse if reform does not come in 12 months. There is no confirmed timeline. The property market will not pause while parliament deliberates. Buyers who time their decision around an uncertain political event rather than current market conditions are, in effect, making a speculative bet on government policy against a known trend of rising prices.

The contractor-specific dimension

Contractors are already predisposed to hesitation in the mortgage market — not through lack of ability to borrow, but through prior experience of rejection by high-street lenders who do not understand contract income. The combination of a mortgage approval uncertainty (will I be accepted on my day rate?) and a stamp duty uncertainty (should I wait for reform?) creates a compounding effect where neither obstacle alone would be decisive, but both together produce inaction.

The mortgage approval question has a definitive answer available right now. A specialist broker can assess a contractor's specific income, identify the lenders who will accept it, and confirm exactly what they can borrow and at what rate — before any application is made. That eliminates one of the two uncertainties completely. What remains is the stamp duty question — and as the numbers above show, the case for acting now is strong regardless of what happens to SDLT.

Acting on what you control

The stamp duty rate is set by the government and cannot be controlled. The mortgage rate environment, lender criteria, and property prices are also largely outside any individual buyer's control. What a contractor can control is their own preparation: whether they have a specialist broker who understands their income, whether they have an agreement in principle from the right lender, and whether they are positioned to act when the right property appears. Getting that preparation right takes days. Waiting for political certainty that may never arrive takes indefinitely longer.
