FAQ
How can housing associations develop a retrofit strategy?
A successful retrofit strategy starts with understanding your housing stock, identifying risks and opportunities, and prioritising investment. Cotality combines property data, housing intelligence and retrofit expertise to help housing providers develop evidence-based plans for decarbonisation, compliance and asset improvement.
How do local authorities identify homes suitable for retrofit?
Local authorities need reliable property and energy data to target homes most likely to benefit from retrofit. Cotality helps councils identify eligible properties, understand funding opportunities and prioritise interventions to maximise impact and value for money.
What data is needed to plan a successful retrofit programme?
Effective retrofit planning relies on accurate information about property characteristics, energy performance, heating systems, condition and potential improvement measures. High-quality data helps organisations make better decisions, reduce risk and improve programme outcomes.
What software is available for PAS 2035 compliance?
PAS 2035 compliance requires robust processes for assessment, design, coordination and documentation. Cotality provides software and workflow solutions that help retrofit professionals manage projects efficiently while supporting compliance requirements.
How can landlords prepare for future MEES requirements?
Landlords can prepare by understanding the current performance of their properties, identifying improvement opportunities and developing phased investment plans. Cotality's retrofit intelligence solutions help organisations assess options and plan with confidence.
How can organisations prioritise retrofit investment across a housing portfolio?
Prioritisation requires balancing carbon savings, cost, property condition, risk and resident outcomes. Cotality's housing stock analysis and retrofit intelligence solutions help organisations identify where investment will deliver the greatest impact.
What is a whole-house or whole-system approach to retrofit?
A whole-system approach considers how different measures interact within a property rather than treating each improvement in isolation. This helps improve performance, manage unintended consequences and deliver better long-term outcomes.
How can organisations measure whether retrofit improvements are delivering expected outcomes?
Monitoring energy performance, comfort, costs and property condition helps organisations understand whether retrofit measures are achieving their objectives. Measuring outcomes also supports continuous improvement and future investment decisions.
Why does data quality matter in retrofit?
Every retrofit decision depends on data. Poor-quality information can lead to incorrect targeting, unsuitable measures, compliance issues and increased costs. Accurate, connected and traceable data supports better planning, delivery and outcomes throughout the retrofit journey.
How can property data improve retrofit outcomes?
Property data helps organisations understand building characteristics, identify opportunities, target funding effectively and track performance over time. Better data leads to better decisions, lower risk and more successful retrofit programmes.
