RETROFIT & DECARBONISATION
Future–Proofing Homes
with Energy–Efficient
Retrofit Solutions
At AEG Construction, we deliver fabric-first retrofit and decarbonisation solutions that transform inefficient properties into comfortable, low-carbon, energy-efficient homes. Reduce heat loss, lower bills, improve EPC ratings, and support the UK’s journey toward net-zero.
Reduce heat loss
Lower carbon emissions and improve overall performance.
Improve EPC rating
Boost comfort, value, and long-term savings.
PAS 2035 aligned
Whole-house planning with quality and compliance in mind.
OVERVIEW
What Is Retrofit and Decarbonisation?
Retrofit is the process of upgrading existing buildings to improve energy performance.
Decarbonisation reduces reliance on fossil fuels by improving insulation, upgrading heating systems, and integrating renewable technologies.
Rather than a single upgrade, retrofit is a whole-house approach — ensuring each measure works together to deliver long-term efficiency, comfort, and performance.
FABRIC-FIRST STRATEGY
Our Retrofit Approach
We prioritise reducing heat loss first, then integrate low-carbon systems — so upgrades work together and deliver measurable outcomes.
Initial Property Assessment
We assess insulation, heating systems, ventilation, and overall energy performance.
Energy Efficiency Improvements
Heat loss is reduced through upgrades to walls, roofs, floors, windows, and airtightness.
Low-Carbon Heating Integration
Where suitable, we introduce air source heat pumps and renewable technologies.
Grant & Compliance Management
We support ECO4 eligibility checks, funding applications, and PAS 2035 aligned compliance.
Installation & Quality Assurance
Delivered by certified installers, backed by guarantees and quality checks.
WHAT WE DO
Our Retrofit Services Include
Whole-house retrofit assessments (EPR and energy performance surveys)
Bespoke retrofit design strategies tailored to property type, age, and condition
Planning for low-carbon measures including insulation upgrades, solar PV, and air source heat pumps
Detailed retrofit roadmaps supporting phased, budget-aware improvements

ECO4 • COMPLIANCE
Energy Efficiency as a Priority
The UK government has identified energy efficiency as a key priority under ECO4 and its wider UK’s net-zero strategy.
This includes:
Homes that undergo deeper retrofit improvements often achieve greater savings — especially when paired with heat pumps and renewables. For homeowners, wider energy efficiency improvements and the PAS 2035 retrofit framework also support a more structured long-term approach.

Frequently Asked Questions (FAQs)
What is the difference between retrofit and renovation?
Renovation focuses on appearance or repairs, while retrofit improves energy efficiency and carbon performance, often involving insulation, heating upgrades, and renewables.
Can retrofit work be done in stages?
Yes. Retrofit can be phased, but we always design it as a whole-house plan to ensure each upgrade works efficiently with future improvements.
Is retrofit disruptive to my home?
Some measures involve minor disruption, but many upgrades, such as external insulation or heating replacements can be completed with minimal inconvenience.
Can retrofit really reduce my energy bills?
Absolutely. A well-planned retrofit can significantly reduce heat loss, meaning your heating system works less and your energy bills drop.
Do I have to pay upfront for ECO4-funded retrofit work?
In many cases, no. If you qualify, ECO4 funding can cover part or all of the cost. We handle the application process for you.
