What is a Whole House Retrofit?
A whole house retrofit is all about looking at your property as one integrated system, rather than doing upgrades in isolation, it examines how insulation, heating, ventilation, sealing, and the building fabric work together. When you treat a home this way, instead of simply adding new pieces here and there, you can make a real difference to comfort, energy bills and long-term performance.
At Efficiency Smart we simplify the process. We’re independent and not tied to installers, meaning our advice is honest, practical and tailored to your home and budget. Whether your goal is to reduce energy bills, cut carbon emissions or boost your EPC rating, starting with a whole house retrofit gives you a strategic, well-informed way forward.
Why a Whole House Retrofit Matters
A retrofit done in a considered way can transform how a property feels and functions. Rather than simply adding a more efficient boiler or replacing windows, you can:
Improve comfort and reduce drafts by addressing insulation, air-leakage and ventilation together.
Cut energy costs and carbon emissions by taking a fabric-first approach rather than relying on single upgrades.
Avoid wasted spend by planning upgrades in the right order – so you don’t invest in heating improvements only to find insulation or ventilation issues limit their effectiveness.
Future-proof your property for upcoming energy regulations by ensuring the whole building performance is raised, not just one element.
With many years of combined experience and accredited under standards like PAS 2035, we provide retrofit assessments and advice that is data-driven but easy to understand. Our focus is always on solutions that work for you – not just chasing grant schemes or installations.

Then we build a plan with practical, affordable improvements that make sense in sequence.
