Getting Ready for the New Decent Homes Standard

An end-to-end, data-led approach to understanding risk and modelling the impact of the New Decent Homes Standard across your portfolio

The New Decent Homes Standard represents one of the most significant shifts facing social housing providers in a generation. Expectations are rising — not just around the quality of homes, but around how confidently landlords can evidence what they know about their stock, understand the risks they are managing, and demonstrate the financial impact of meeting the new standard across their entire portfolio.

This is no longer about isolated surveys or high-level compliance statements. Providers are now expected to show a clear line of sight from individual homes to portfolio-wide risk and investment decisions.

That requires an end-to-end, data-led approach — and that is where ARK Consultancy can help.

Why housing stock data now needs to be different

Under the old Decent Homes Standard, stock condition data was largely used as an asset management tool. If a property passed basic tests for condition and thermal comfort, the detail often mattered less.

The new Decent Homes Standard changes that fundamentally.

It shifts expectations from periodic compliance checks to ongoing, evidenced assurance. Providers are now expected not just to hold data, but to demonstrate an accurate, up-to-date understanding of the condition and risks within their homes.

Several key changes drive this shift:

• Decency is now explicitly linked to resident safety and health.
  Damp and mould is a standalone failure under the new standard, with an expectation of early intervention and prevention. This means data must capture risk indicators — ventilation, heating performance, building characteristics — not just visible defects.
• Energy efficiency has moved from aspiration to requirement.
  Minimum Energy Efficiency Standards introduce clear compliance deadlines. Providers need data that shows which homes will fail in the future, what work is required, and when investment must be made.
• The definition of “reasonable repair” has expanded.
  Kitchens, bathrooms, ventilation systems, lifts and fire safety systems now directly affect decency. Survey data that only records age or replacement cycles is no longer enough — actual condition and functionality matter.
• Regulation is now proactive and data-led.
  Providers are expected to understand patterns and hotspots across their portfolio, not just respond when issues are raised. That requires consistent data standards, audit trails and confidence in coverage.
• Boards and executives need evidence, not reassurance.
  Questions are becoming sharper: How many homes fail today? Which are at risk? What is the cost of compliance — and the cost of delay? These can only be answered with data aligned to the new standard.

In short, providers now need stock data that is aligned to the new Decent Homes criteria, captures risk as well as condition, and supports portfolio-wide decision-making.

One joined-up solution — from housing data collection to portfolio decisions

ARK supports social housing providers at every stage of preparing for the new Decent Homes Standard. We help organisations collect robust property data, understand what it tells them about risk, and model the financial implications of compliance — all the way through to strategic, data-led portfolio decisions.

Rather than treating these as separate exercises, ARK provides a single, coherent approach that allows providers to see the full picture.

Step one: collecting the right property data

Readiness starts with knowing your homes properly. Many providers still face challenges with incomplete survey coverage, inconsistent approaches over time, or asset data spread across multiple systems.

ARK helps providers establish strong foundations by:

• Designing rolling stock condition survey programmes that are statistically robust and practical to deliver.
• Developing survey templates and data standards aligned to the new Decent Homes requirements — including damp and mould risk, key building components and energy performance.
• Delivering surveys in formats that integrate with existing systems, including handheld data capture where required.
• Targeting inspections using repairs data and known risk profiles, such as archetypes associated with higher damp, mould or HHSRS risk.
• Cleaning, consolidating and validating existing asset data to improve confidence and reduce reliance on assumptions.

The result is property data that can be trusted — and used.

Step two: understanding portfolio-wide risk

Once the data is in place, providers need to understand what it means. The new Decent Homes Standard requires landlords to identify where homes fail — or are at risk of failing — and to prioritise action based on risk to residents and the organisation.

ARK helps providers:

• Identify homes that currently fail or are likely to fail the new standard.
• Understand patterns of risk across the portfolio, not just individual properties.
• Highlight issues linked to damp and mould, disrepair, safety systems and building types.
• Produce clear, evidence-based reporting that supports regulatory assurance and board scrutiny.

This gives leadership teams confidence when answering difficult questions: Where are our biggest risks? Which homes should we prioritise? What happens if we delay?

Step three: modelling the financial impact of the new standard

Meeting the new Decent Homes Standard will require sustained investment over time. One of the biggest challenges for providers is understanding the true cost, timing and trade-offs involved.

ARK brings data and risk insight together to:

• Model the portfolio-wide cost of meeting the new Decent Homes Standard.
• Forecast future investment requirements using real stock condition data.
• Test different scenarios to understand affordability, delivery options and risk.
• Support the development of long-term investment strategies and shorter-term, deliverable programmes.
• Present clear, evidence-based options to boards and executives.

This ensures financial planning is transparent, defensible and aligned to regulatory expectations.

Bringing it all together: data-led portfolio decisions with ASAP

ARK’s Strategic Asset Performance (ASAP) model is the point where data, risk and finance come together.

ASAP combines stock condition data, risk insight, financial performance and contextual factors to show how homes are performing at a portfolio level. Clear, accessible outputs — including traffic-light ratings — allow boards and executives to understand the implications of different investment choices and make confident, evidence-based decisions.

In a world of tighter budgets and higher scrutiny, ASAP helps ensure investment is targeted where homes have a sustainable future.

Why an end-to-end approach matters

Providers that treat data collection, risk management and financial planning as separate exercises often struggle to demonstrate control and confidence. Those best placed to be ready for the impact of the New Decent Homes Standard will be able to show a clear, evidence-backed link between property condition, risk and investment decisions.

ARK’s end-to-end approach — from data collection, through risk and financial modelling, to strategic portfolio decisions using ASAP — helps providers do exactly that.

Getting ready for the new Decent Homes Standard isn’t about last-minute compliance. It’s about understanding your homes, managing risk proactively, and making confident, data-led decisions about the future of your portfolio and the investment requirements.

If that’s on your agenda, ARK Consultancy can help.
