Most commentary on the new Decent Homes Standard has focused on what landlords must do, but fewer people have asked what it will cost, and fewer still have asked what happens to those who have not planned the financing in advance. That question is, in my view, where the real problems arise.
The government published its policy statement on 28 January. For the private rented sector, it is a landmark moment. The first time a single quality benchmark has been applied equally to social and private rental homes. The enforcement date is 2035, and that number has a "sedative" quality, encouraging landlords to read the headline, nod, and park it. The problem is that the conditions shaping how affordable and accessible improvement finance will be in 2033 or 2034 are being set now, not then.
The detail carries financing implications that the broad-brush coverage has largely missed, so it is worth being specific about what the standard requires.
Five criteria sit at the heart of it, and the financing implications differ across each one.
The first is the most familiar. Homes must be free from category one hazards under the Housing Health and Safety Rating System, the most serious structural, electrical and fire risks that put occupants in genuine danger. This has always been a legal obligation, but the standard strengthens the enforcement machinery around it considerably.
The second is more nuanced. A new condition-based test replaces the old age-based rules that determined when a kitchen or bathroom needed replacing. Both now become "key components," assessed on their actual condition rather than how long they have been there. A well-maintained kitchen fitted twenty years ago passes, however a poorly maintained one fitted recently might not. For landlords who have invested consistently in their stock, this rewards them, but for those who have deferred maintenance, the reckoning is now baked into regulation rather than left to their discretion.
Third, core services must be present and safe, with a specific new requirement for child-resistant window restrictors wherever falls are a risk.
Fourth, and most financially significant, homes must meet stronger standards of thermal comfort and energy efficiency, which I will address below.
Fifth, damp and mould are now a standalone requirement, sitting alongside Awaab's Law and the Renters' Rights Act 2025 as part of a coordinated push rather than a set of parallel initiatives.
The energy efficiency requirements are where the picture becomes genuinely complex and where I think the gap between perception and reality is widest. The standard mandates whole-home programmable heating as a baseline and works alongside the Minimum Energy Efficiency Standards regime, whose specific private rented sector requirements will arrive in separate regulations.
What has received almost no attention is that the EPC methodology itself is changing this year. The existing framework has weighted carbon emissions and running costs heavily, but the new one shifts emphasis towards insulation quality, heating system efficiency and smart technology.
Properties currently rated EPC C under the old system may not reach that threshold under the new one, and a landlord who believes their portfolio is energy-efficient because their current certificates say so may be operating on information that is about to become out of date.
This matters for financing in a direct way. Lenders are not waiting until 2035 to factor energy performance into their risk assessments. Green mortgage products offering preferential rates for higher-rated properties already exist and are growing, while lenders are increasingly attentive to the long-term value of stock that does not meet evolving standards.
A landlord who arrives at a remortgage in two or three years with a property needing significant energy efficiency works may find their options narrower and their rates higher than expected.
The case for early action goes beyond spreading the cost of works. It is about accessing improvement finance before a wave of landlords chase the same contractors and products in the years approaching 2035. Anyone who remembers the scramble for insulation during the energy crisis will recognise the pattern.
A practical starting point is an audit of your current portfolio against the five criteria, with particular attention to damp, mould and window safety as the most immediately enforceable. Any energy efficiency assessment should account for the new EPC methodology, not the old one. The question to ask is not whether your properties meet today's standard, but whether they will meet the one that applies when your next mortgage review arrives.
The landlords who manage this period well will be those who treat the standard as a portfolio planning exercise, with a financing dimension that is at least as important as the compliance one.
