The rate movements in detail

West Brom Building Society has made the larger of the two moves. Its 95% LTV 2-year fixed rate fell 26 basis points to 5.58% (no product fee). The 90% LTV equivalent fell 22 basis points to 5.08% (with a £999 fee). These are meaningful cuts that place West Brom competitively in the higher-LTV market where first-time buyers and those with smaller deposits are most active.

TSB's cuts are more modest but still directionally significant: residential 2-year fixed deals at 60% and 90% LTV were trimmed by up to 15 basis points. These cuts signal continued downward pressure on fixed pricing, consistent with the broader market trend of lenders adjusting rates as swap rate conditions allow. The direction of travel remains downward, even if the pace is gradual.

Why rate cuts don't solve the contractor income problem

TSB and West Brom cutting rates is genuinely good news for borrowers — in principle. But both lenders, like the majority of high-street institutions, assess income based on payslips and employment contracts. A contractor running a limited company and billing £500/day will typically be assessed on their most recent accounts: a salary of £26,000 and dividends bringing declared income to perhaps £52,000.

At TSB or West Brom's 4.5x income cap, that £52,000 assessment produces a maximum mortgage offer of £234,000. The correct calculation — day rate × 5 × 46 weeks = £115,000 annualised income — produces a mortgage capacity of £517,500 at the same multiple. The gap of £283,000 is not a product of the rate cut. It is a product of the income assessment methodology. And a 26 basis point rate cut does nothing to close it.

What the rate cutting trend signals for the market

Multiple lenders cutting rates in May 2026, even modestly, signals that the worst of the rate spike is likely past. Swap rates have been volatile but the direction of travel is downward. For contractors planning to lock in a fixed rate, this is relevant: acting now means accessing improving rates while they continue to gradually fall, with specialist lenders offering the correct income assessment alongside competitive pricing.

The risk of waiting indefinitely is that rates stabilise or move back up — which could happen quickly if gilt yields spike again on political or geopolitical news. The BoE's rate pause signal for June and July provides some near-term stability, but the market can reprice faster than the MPC cycle.

The specialist lender advantage for contractors

Specialist contractor lenders work differently from TSB and West Brom. They assess income using the annualised day rate — not salary and dividends. They understand that a contractor on £500/day is a high-quality borrower, not an unusual risk. And they price accordingly. Day Rate Finance works exclusively with lenders who use the correct methodology, ensuring that the borrowing capacity unlocked by your day rate is not left on the table because you applied to the wrong institution.

When mainstream lenders cut rates, the specialist lenders that Day Rate Finance works with also typically respond to the same swap rate environment. The benefit of the improving rate trend is available to contractors — it just needs to be accessed through the right channel.
