What is a Retrofit Assessment?

Every home that requires an energy retrofit must first be assessed by a Retrofit Assessor who has been trained and qualified in accordance with PAS 2035 and who is certified by a Retrofit Assessor Scheme. The Retrofit Assessment is completed on-site and is an in-depth assessment of the property, based on 3 key components…

An Energy Report

A Condition Report

An Occupancy Assessment

These are needed to understand what measures are required to improve the energy efficiency of the home and will be used by a Retrofit Coordinator who will advise on the design, installation and timeframe for the recommendations outlined in your assessment.

Our eco-apt Retrofit Assessor is part of the Elmhurst Energy’s Accreditation Scheme, TRUSTMARK registered and fully insured. The retrofit assessment can take 2-3 hours with the completed report being produced within 3-4 working days following the appointment.

What are some of the most common types of retrofit?

Some of the most common measures identified in a retrofit assessment are:

Upgrading the insulation - This can include internal and external wall insulation as well as loft insulation. The big benefit is that this can help keep a home warmer in the winter and cooler in the summer whilst helping to reduce energy bills.

Upgrading the heating system - A more efficient heating system can help to reduce energy usage and bills whilst making a home more comfortable to live in. This type of retrofit is often done in conjunction with upgrading the insulation for maximum energy efficiency.

Adding solar panels - As well as having the potential to increase the value of a home, solar panels are a great way to reduce a property's carbon footprint and make it more energy-efficient.

Installing new windows - This type of retrofit can make a big difference to the energy efficiency of a home, helping to reduce noise pollution whilst improve the overall appearance of the property.

Installing new doors - Another type of retrofit that can help to improve the energy efficiency and appearance of a home.

What is PAS 2035?

PAS 2035 is the standards framework for the end-to-end delivery of domestic retrofit work that came into force following the 2015 government commissioned ‘Each Home Counts’ review. It provides a whole building approach to the retrofit process, centred around the home’s occupancy, environment and the householder’s improvement objectives when determining what suitable energy efficiency and renewable energy measures to install.

PAS 2035 requires that every home requiring an energy retrofit must first be assessed by a retrofit assessor who’ll provide detailed information about the home to a retrofit coordinator. The government have made clear that any funding they give for energy efficiency measures will need to go through the PAS 2035 process.

PAS 2035 does not apply to like-for-like replacement, maintenance or repair of any system already installed in a home that does not improve the energy efficiency, ventilation or carbon dioxide emissions of the property.

The 3 components of a Retrofit Assessment

A Retrofit Assessment consists of three key reports that create an overview of the whole property, its current usage and potential.

Energy Report - This report looks at the construction and overall dimensions of the property, including all windows and door openings. It will include an assessment of the property’s ventilation, heating, hot water and lighting systems and their controls, and look at any energy efficiency measures already installed or proposed. It will also establish the thermal transmittances (U values) of the building fabrics and the suitability of the property for improvements. It’s important to note that the Energy Report is NOT an Energy Performance Certificate (EPC).

Condition Report - This survey (not a full structural survey) looks at the overall condition of the property including all internal rooms and loft space. It is used to identify any signs of defects that could potentially affect any future energy efficiency improvements. Where defects are found (such as penetrative damp), these should be rectified before any further improvements can be made. Where it’s identified that the home has built pre-1919, an additional Significant Survey Checklist would be completed.

Occupancy Assessment - The key purpose of this assessment is to model how energy is used in the home. For this, the retrofit assessor will discuss a wide range of topics with the householder such as occupancy, water usage, heating, appliances and cooking, as well as meter readings and energy bills over the previous year to identify any usage patterns.

Upon completion, you will be presented a comprehensive report that will include the Energy Report, Occupancy Evaluation and Condition Report, helping you make an informed decision on the potential steps you can take to make your home more energy efficient.

Frequently asked questions

A retrofit assessment plays a critical role in improving the energy efficiency and sustainability of a property, giving homeowners valuable insight into the specific measures they can take. Retrofit assessments can also help with accessing funding opportunities like ECO4 (Energy Company Obligation) and GBIS (Great British Insulation Scheme). Other benefits include:

Identifying poor energy performance - An assessment can help pinpoint areas in your home where energy is being wasted. This can include poorly insulated walls and openings, outdated heating systems, or inefficient lighting, as well as structural integrity issues such as damp and mould. By identifying these areas, homeowners can take targeted actions to address them effectively.

Energy-saving recommendations tailored for your home - Recommendations could include upgrading the insulation or heating system and controls, or installing renewable energy solutions such as Solar PV or an Air Source Heat Pump. With energy prices expected to remain high, investing in retrofit measures could help future-proof your property and lead to significant long-term savings.

Critical data for the retrofit designers - Data and insights gathered in a retrofit assessment is used by retrofit coordinators and designers to determine what energy efficiency measures are feasible and should be installed. Without this, the overall retrofit plan would lack accuracy and risk non-compliance with PAS 2035.

Provide cost-benefit analysis - A retrofit assessment will provide a cost-benefit analysis of the proposed energy saving measures, helping homeowners better understand the financial implications of retrofitting and the potential savings to energy bills.

Reducing Carbon Footprint - Implementing the recommendations in a retrofit assessment such as upgrading the heating system or installing more energy efficient appliances can help homeowners significantly decrease their carbon emissions.

Compliance with PAS 2035 - Retrofit assessments are a key part of compliance with PAS 2035, the mandated government standard for domestic retrofit projects.

Regulatory Compliance - Installing measures identified in a retrofit assessment can help ensure your property meets energy regulations and standards such as the minimum EPC rating of E for rental properties, therefore avoiding potential penalties.

Once you have instructed us to conduct the retrofit assessment, we’ll go through a set of questions in a phone call regarding your property and your project. The scope of each retrofit assessment varies depending upon the risk path designated by the retrofit coordinator, the type of property and the number of improvement measures involved.

Prior to us attending your property to conduct the retrofit assessment, you’ll need to gather the below information and relevant documentation for the assessor on the day:

Approximate age of your property

Last 12 months of gas and electricity bills

Number and age of any extensions with supporting documentation such as Building Regulations Completion Certificates

Sign off documents for any rooms in the roof

All warranties, certificates and any installation paperwork for any cavity wall and loft insulation, boiler, hot water cylinder, extractor fans, air source heat pump, solar panels and any battery storage.

The retrofit assessment will complete the following 3 key reports at your property:

Energy Report - The assessor will record the construction and overall dimensions of the property, including all windows and door openings. They’ll assess the property’s ventilation, heating, hot water and lighting systems and their controls, and look at any energy efficiency measures already installed or proposed. The information collected from all rooms including the roof and loft space is recorded in detail on a floorplan.

Condition Report - The assessor will check for any signs of deterioration or structural damage that may require attention, as well as potential hazards such as electrical problems or fire risks . They’ll assess the condition of the walls, floors, windows and doors as well as the roof to determine their effectiveness in preventing heat loss or heat gain. All issues such as cracks, damp, mould and leaking gutters are noted, photographed and recorded in the report.

Occupancy Assessment - The assessor will discuss with you all the things that impact your energy use, such as number of occupants, heating, appliances and cooking, as well as water usage. They’ll look at your meter readings and energy bills over the previous year to identify any usage patterns. The more information they can collect, the more accurate your assessment will be.

Once all the data has been collected, we return to our office to complete the calculations, reconcile energy bills and upload evidence before we can produce the final report. We lodge the final report on the Data Warehouse and provide a copy to the Retrofit Coordinator that’s PAS 2035 compliant.
