In contrast, marine-grade stainless steel offers exceptional
resistance to corrosion, even in harsh environments.
Combine that with proper glazing specification, such as selfcleaning, solar-control glass, and a building gains not just
durability but enhanced comfort and sustainability.
Because in the end, whether you’re insulating a post-war
terrace or restoring a Georgian farmhouse, the same truth
applies: cutting corners always costs more.
And for heritage buildings, those costs are not just financial,
they are cultural, architectural, and irreversible.
That’s the irony of cost-cutting: by stripping away quality
materials, you often increase a building’s whole-life carbon
footprint, maintenance requirements and replacement
frequency. It’s the polar opposite of what a sustainable
retrofit should achieve.

Trust, craftsmanship, and cultural change
If there’s one positive message to take from the ECO4
revelations, it’s that scale without standards doesn’t work.
Ambitious sustainability goals are meaningless unless
the delivery mechanisms are grounded in competence,
craftsmanship, and trust.
For heritage and conservation buildings, those values are
already embedded in best practice. Conservation officers,
architects, and specialist manufacturers understand that
longevity and authenticity go hand in hand. But for this
ethos to survive, clients and contractors need to resist the
temptation to “do it cheaper”.
Retrofit must evolve from being seen as a commodity to
being understood as a craft, one that values durability, design
integrity, and technical excellence.
At Stella Rooflight, we’ve built our business around
that principle. Every rooflight we make is individually
manufactured to order, using 316L stainless-steel frames,
hardwood liners, and glazing options selected for the
building’s specific needs. That approach isn’t about luxury;
it’s about doing things correctly. In conservation work,
correctness is sustainability, because it ensures the building,
and its components, last for generations.
A call for quality over quantity
The failures of ECO4 and the Great British Insulation
Scheme should be more than a cautionary tale, they should
be a turning point.
Retrofit, whether for energy efficiency or conservation, is not
a numbers game. It’s a stewardship responsibility. If we are
serious about decarbonising Britain’s building stock, we must
stop treating retrofit as a race to the bottom.
Architects and specifiers have enormous influence here.
Every time a specification retains the correct heritage
material rather than an imitation, it sends a signal that
quality matters. Every time a practice chooses a trusted local
specialist rather than the cheapest national installer, it helps
rebuild the culture of competence our sector so urgently
needs.
