Barclays has eased its buy-to-let affordability rules, a move that could let some landlords borrow up to £20,000 more as financing conditions stay tight ahead of the Renters’ Rights Act.
The lender said it has introduced a dynamic stress rate for buy-to-let cases, calculated as a fixed margin above the rate on the chosen product rather than relying on a more rigid standard test. Barclays said the change should reflect a borrower’s actual deal more closely while keeping lending responsible.
For landlords, the timing matters. Mortgage pricing has been volatile since late March, and that has already reduced product choice across the market. In that context, lenders that can improve affordability without cutting headline rates may have a better chance of winning remortgage and purchase business from landlords still willing to expand.
How the Barclays change affects landlord borrowing
According to Barclays, a single buy-to-let borrower earning £40,000 and buying a £250,000 property with expected annual rent of £12,150 could borrow up to £20,000 more under the new approach.
That will not transform every deal, but it could make the difference on marginal cases where rental cover has been the sticking point. It also gives brokers and landlords another sign that lenders are starting to compete on policy again, not just on rate cards.
Landlord Knowledge has already covered Paragon’s push to support landlords with higher mortgage limits and the recent squeeze on landlord mortgage choice. Barclays’ latest move adds another layer to that trend, but it also shows where competition is heading: lenders are trying to improve borrowing power without taking the risk of headline rate cuts that may need to be reversed quickly.
Why lenders are shifting from rates to affordability
For landlords, policy tweaks can matter as much as a small change in rate. A cheaper mortgage is useful only if the deal passes underwriting. In a market where swap rates have been moving around and product withdrawals have been frequent, easing affordability tests can be a more durable way for lenders to keep business flowing.
The practical point is that this kind of change tends to favour experienced borrowers with cleaner cases and decent rental cover, rather than landlords already stretched by higher debt costs. It may help more landlords refinance or move, but it does not remove the wider pressure from higher funding costs and tighter margins.
This follows Landlord Knowledge’s recent report on mortgage deals vanishing in just eight days, which showed how quickly lender appetite can change when wholesale markets turn. Barclays’ update points the other way, suggesting some lenders still want to back landlord borrowing where the numbers work.
Landlords wanting to test the new rules will still need to watch product pricing, fees and rental stress assumptions carefully. A more generous affordability model can open the door, but it does not guarantee that the overall deal is competitive once costs are added up. Barclays has set out the broad change on its buy-to-let mortgage pages.
What this means for landlords
- If you’re remortgaging: Recheck cases that previously failed on rental cover or affordability, especially if the shortfall was modest.
- If you’re buying: Extra borrowing room may help on smaller deals, but fees and stress tests still need close comparison across lenders.
- Watch for: More lenders using criteria changes, not just headline rate cuts, to compete for landlord business this spring.
- Bottom line: Barclays has improved the maths for some landlords, but the wider borrowing backdrop is still fragile.
Editor’s view
Barclays is making a sensible move. In the current market, landlords need workable underwriting more than flashy pricing. The warning is that a bit more borrowing power does not fix weak yields or expensive deals, so this is helpful rather than game-changing.
