Get expert PAS 2035 guidance for compliant, high-quality retrofit projects across the UK. Compliant Retrofits provides practical PAS 2035 advice, technical support and consultancy to help homeowners, landlords, contractors and housing providers meet current retrofit standards with confidence.
What Is PAS 2035 and Why Does Your UK Retrofit Project Need It?
PAS 2035 is the recognised UK framework for managing energy-efficiency improvements in existing homes and buildings. It sets out a structured process for assessing, designing, installing, monitoring and evaluating retrofit measures so that projects are safe, effective and suitable for the property.
With professional PAS 2035 guidance, homeowners, landlords, installers, housing providers and local authorities can reduce compliance risks and improve the quality of retrofit work. Compliant Retrofits provides practical PAS 2035 advice, support and consultancy for projects across the UK.
Why PAS 2035 matters
Supports access to funded retrofit schemes — PAS 2035 compliance is commonly required for ECO4 and other publicly funded energy-efficiency programmes
Reduces the risk of poor-quality installations — the framework introduces clear oversight, accountability and quality controls throughout the project
Improves energy-performance outcomes — measures are assessed and designed as part of a whole-house approach rather than installed in isolation
Protects the building and its occupants — helps identify risks such as condensation, damp, inadequate ventilation and unintended heat loss
Creates a clear compliance pathway — responsibilities are defined from the initial assessment and design stage through to installation, handover and monitoring

Frequently Asked Questions
Do I need PAS 2035 guidance for ECO4-funded retrofit work?
PAS 2035 compliance is generally required for retrofit measures delivered through ECO4. Professional PAS 2035 support helps ensure the project follows the correct assessment, design, coordination and documentation process.
How long does PAS 2035 compliance take?
Timelines depend on the property, project complexity and number of retrofit measures involved. A straightforward insulation project may take several weeks, while projects combining insulation, heating, ventilation or renewable technologies can take longer.
How much does PAS 2035 consultancy cost?
The cost depends on the property size, risk pathway, required assessments and scope of work. Contact Compliant Retrofits for a tailored quotation and information about potential funding support.
What is the difference between PAS 2035 and PAS 2030?
PAS 2035 covers the overall retrofit process — assessment, design, coordination, installation oversight and evaluation. PAS 2030 focuses on the requirements installers must meet when fitting energy-efficiency measures.
Can a homeowner act as their own Retrofit Coordinator?
A Retrofit Coordinator must hold the relevant recognised qualifications and demonstrate the required competence. Most homeowners therefore need professional PAS 2035 advice and coordination support.
Does Compliant Retrofits provide UK-wide PAS 2035 support?
Yes. Compliant Retrofits provides PAS 2035 guidance, advice, support and consultancy for homeowners, landlords, contractors, housing providers and local authorities across the UK.
