Retrofit assessment

Retrofit assessor for better whole-house decisions

Understand the property before planning insulation, heating and other energy-efficiency improvements.

Whole-property view

Look beyond a single measure and understand how the building, condition, occupancy and improvement options interact.

Evidence-led decisions

Use property information to support more considered improvement planning rather than choosing measures from a generic list.

Complement an EPC

An EPC provides a standardised energy rating; a retrofit assessment can add broader context when a property is being upgraded.

What is a retrofit assessment?

A retrofit assessment is a more detailed look at a dwelling for the purpose of planning energy improvements. It considers the building as a whole rather than focusing only on the headline EPC score. The exact scope depends on the project, standard and scheme involved.

When is it useful?

It can be valuable when a homeowner, landlord or project team is considering several interacting measures—such as insulation, ventilation and heating changes—or when the property has constraints that make a generic improvement list unsuitable.

EPC versus retrofit assessment

An Energy Performance Certificate is a standardised certificate with an A–G rating. A retrofit assessment is used to build a deeper picture for improvement planning. The two can complement each other, but they are not interchangeable.

Why a whole-house approach matters

Energy upgrades can affect moisture, ventilation, comfort and heating demand. That is why major projects should consider how proposed measures work together. This is especially important in older or traditional buildings where inappropriate changes can create unintended consequences.

What information may be considered?

Depending on the project, assessment work can consider construction, condition, ventilation, existing services, occupancy context and potential measures. The output should support the next stage of design or coordination rather than simply produce a marketing score.

Request a retrofit assessment

Send the property address, type, the improvements you are considering and any project or funding requirements that apply. That information helps determine the correct scope before an appointment is arranged.

Frequently asked questions

Common questions

What is a retrofit assessment?

It is a property assessment used to build a fuller picture for planning energy-efficiency improvements.

Is a retrofit assessment the same as an EPC?

No. An EPC provides a standardised energy rating; a retrofit assessment can provide broader property context for improvement planning.

When should I consider a retrofit assessment?

It is especially useful when you are planning several interacting measures or dealing with a complex or older property.

Does retrofit only mean insulation?

No. A whole-house approach can consider fabric, ventilation, heating, hot water, controls and other relevant measures together.

What should I send for a quote?

Provide the property address, type, planned improvements and any project or funding requirements that may affect the assessment scope.
