Sustainable Wedding Alliance 2025 Impact Report
of couples are now considering sustainable elements in their wedding plans.*
Up 11 percentage points in a single year. The demand is real, it’s growing, and couples are getting better at telling the difference between businesses that mean it and businesses that just say it.
In an industry where anyone can claim to be sustainable, proof is the differentiator. Not pledges. Not good intentions. Independently verified, documented, communicable proof.
Welcome to our 2025 impact report. Here’s what five years of building that proof looks like.
I became a sustainable wedding supplier in 2019 but had only just scratched the surface until I became a Sustainable Wedding Alliance member in December 2021. The SWA has completely changed my business.

Member Stories
Thirty–one businesses now carry our accreditation. This is the one that proved it could be done.
Hayne House was our first ever accredited venue. The framework was brand new. So was the question hanging over it: would this actually work?
In 2020, they pledged to cut their Scope 1 and 2 emissions in half by 2025. They got there two years early in 2023, achieved through solar power, greener energy suppliers, and a sustained push to bring the whole team and their contractors along with them.
The ripple spread fast. Waste down 56%, with everything left over diverted from landfill. A Conscious Menu, with carbon footprints disclosed on dishes so couples can see exactly what they’re choosing. A donation to the Kent Wildlife Trust for every couple who booked in 2023. Carbon Literacy Training opened up not just to their own team, but to wedding professionals across the industry.
Hayne House Events Venue won the Net Zero Leaders Award. This is a true testament to the dedication of our entire team.
– Fleur Record Smith, CEO, Hayne House
Our first accredited venue showed what our framework is capable of. Every business since has been building on that.
Hayne House proved the framework works at venue scale. Crockwell takes it somewhere most businesses never reach.
Most businesses are working towards net zero. Crockwell got there and kept going. Through a 400-acre countryside stewardship programme — turning former agricultural land into wildflower meadows — the farm now draws down more carbon than it emits, making it carbon negative on a whole-site basis.
The transformation reaches further than the land. Crockwell pays every employee a living wage, significantly above the industry average for skilled work. They’re already running a 50kW solar array, with battery storage and EV charging points for guests, suppliers, and staff on the way. From Spring 2026, they started only recommending suppliers who have a public sustainability policy and carbon reduction plan of their own.
Crockwell is also helping us develop a venue code of conduct, because the way they’ve structured their supplier relationships is increasingly the model for how venues across the industry can amplify their impact. When a venue of Crockwell’s scale makes sustainability a condition of partnership, the ripple doesn’t stop at the farm gate.
Our team is actively seeking sustainable solutions to the many problems we face, and are deeply invested in the changes we wish to make.
– Amy Cox, Director, Crockwell Farm
For Crockwell, carbon negative isn’t the finish line. It’s the new baseline.
Crockwell proved sustainability works at landscape scale. These next two prove it works at any scale.
One is a small grower in the North, raising her own stems and buying in only what she can’t grow herself. The other is a bigger operation in the South, with a sizeable team, a wholesale book, and a community built around pick-your-own days and open events. Different scale, different model, same result: sustainability and growth, moving together.
Cumberland Flower Farm grows 85% of what it uses, sourcing the rest from British growers. Nothing is imported. That local-first approach saved 28 tonnes of CO₂e against imported alternatives last year, the equivalent of 31 return flights between London and New York, across 962 plastic-free, compostably-wrapped bouquets sold. None of it has slowed the business down: turnover is up 40% in 2025, and has doubled since 2022.
My business has grown significantly. I highly recommend SWA to all wedding suppliers looking to become more sustainable.
– Harriet Smithson, Cumberland Flower Farm
Featherstone Flowers made a founding decision to use only British-grown stems, cutting their carbon footprint by up to 90% against the industry average, from day one. Since then, the business has grown substantially while emissions barely moved, and their carbon intensity per employee now sits well below the UK office average. They’ve reached over 800 people through workshops, open days, and demonstrations, and recently brought sustainable, foam-free flowers into local funeral services. This was one of the first shifts of its kind in a traditionally high-impact corner of the industry.
Sustainability is not a sideline but the foundation of our business.
– Katie Stone & Jess Roberts, Directors, Featherstone Flowers
Two businesses, two scales, two ends of the country. The same proof: doing this properly is good for business.
Cumberland and Featherstone built sustainability into their values from day one. Pippley didn’t get the same head start, which is exactly why their story matters.
It wasn't that we didn't care about it; we didn't understand it well enough.
– Emma Davidson, General Manager
That’s how Pippley describes the first decade of running their Nottinghamshire events venue. Caring about the bats, birds, and bugs sharing their walled garden, but without the framework to do much about it.
What changed: Nottinghamshire’s first SWA-accredited venue, and the Judges Choice Award at the 2025 SWA Summit. Nine team members trained in Carbon Literacy. The garden turned completely chemical-free. The bar switched to UK-only spirits. Imported avocados were replaced with a homemade plant-based alternative. Even their website got an overhaul, rebuilt on 100% renewable hosting, cutting carbon emissions per page view by 91%.
The ripple reached the team, too. Hospitality has a notoriously high churn rate, but Pippley’s core team of 14 has stayed together. Mental health first aiders. Paid sick and parental leave. And in 2025, the Pippley Ramblers: a staff walking group that hiked Mam Tor together.
Mam Tor gave us togetherness, a sense of pride, and a moment to look round at each other and think: “These are my people.
– Abi Leslie, Marketing Executive
A few years ago, Pippley wouldn’t have known where to start measuring any of this. Now they’re publishing an impact report themselves.
Pippley shows what’s possible when a business starts from scratch. But what about the ones who don’t need to?

The Wellbeing Farm didn’t need anyone to tell them how to be sustainable. They became one of the first independent wedding venues in the world to achieve B Corp certification, much of it through their own determination, long before SWA was part of the picture. They joined us anyway, went through the full accreditation process, and in doing so discovered things about their own business they hadn’t measured before. Proving you’re sustainable, and keeping that proof alive year after year, is easier alongside a community built to do exactly that.
To change the way the world sees hospitality.
– The Wellbeing Farm
Five years ago, the Sustainable Wedding Alliance was one small, sustainable business with a mission. Today, it’s the reason 31 UK wedding and hospitality businesses can prove they’re sustainable, not just claim it. And the reason 158 businesses and counting are somewhere on that same path.
A flower farm in Cumbria. A walled garden in Nottinghamshire. A 400-acre farm in Northamptonshire, now giving more back to the land than it takes.
None of these businesses set out needing each other. But together, they’re proof that one small organisation, with the right framework and the right community behind it, can ripple outward into staff, into suppliers, into couples, into whole industries doing things differently.
That’s the real impact of the Sustainable Wedding Alliance. Not one sustainable business. Dozens of them. And still growing.
