Complete Guide to Sustainable Period Care Options in the UK [2026]

I'll start with a confession: my zero-waste journey hit a significant obstacle around, well, periods. For months I was separating my recycling, bringing my own bags everywhere, and feeling generally virtuous about my environmental choices—while completely ignoring the 11,000 disposable products the average menstruating person uses in their lifetime. The cognitive dissonance was spectacular.

The thing is, sustainable period care felt overwhelming. Menstrual cups seemed intimidating. Reusable pads felt like going back to the Victorian era. And period pants? I wasn't convinced they actually worked. So I kept buying plastic-wrapped pads and telling myself I'd look into alternatives "next month."

That was three years ago. Since then, I've tried pretty much every sustainable period option available in the UK—some successfully, some disastrously, and all informatively. This guide is what I wish I'd had at the start: an honest rundown of your options, what actually works, and how to find what suits your body and lifestyle.

The Environmental Reality

Before we dive into solutions, let's talk numbers. Because when I finally looked at the data, I understood why this matters.

In the UK alone, an estimated 28,114 tonnes of menstrual waste is generated annually. That's roughly the weight of 2,800 double-decker buses. Every year. And here's the uncomfortable truth: up to 90% of disposable pads are made from plastic. Those "cotton" pads? Mostly plastic with a cotton topsheet.

Single-use menstrual products are among the most frequently collected items in beach clean-ups across the UK—an average of 5 pieces every 100 metres. I found that statistic genuinely shocking when I first read it.

The environmental case for switching is clear. A woman switching from tampons to a menstrual cup would have 16 times less carbon impact, saving roughly 7kg of CO2 equivalent per year. Multiply that across a lifetime, and you're looking at significant change from a single swap.

But I'm not here to guilt anyone. Sustainable choices need to work for your actual life. So let's look at what's available.

Menstrual Cups: The Most Sustainable Option

If we're ranking purely by environmental impact, menstrual cups win decisively. A recent Life Cycle Assessment found that cup users produce 99% less waste than pad users. Not 50%, not 80%—ninety-nine percent.

A menstrual cup typically costs around £20 and lasts up to 10 years with proper care. Compare that to roughly £130 per year on disposables, and you're looking at savings of about £1,300 over a decade. The maths is compelling even before you factor in the environmental benefits.

How They Work

Menstrual cups are small, flexible cups (usually medical-grade silicone) that you fold and insert. They collect rather than absorb menstrual blood, and most can be worn for up to 12 hours—brilliant for long workdays or overnight.

Brands like Mooncup pioneered this space in the UK. &SISTERS by Mooncup now offers the Nüdie Period Cup, which continues that legacy. These British-made options have proper sizing guides and customer support, which matters when you're learning something new.

My Honest Experience

I won't pretend there wasn't a learning curve. My first attempt involved a public toilet, mild panic, and a solid five minutes of questioning my life choices. The second time was better. By the third cycle, I genuinely couldn't imagine going back.

What surprised me most was the cleanliness aspect. Because the blood is collected rather than absorbed, there's less odour. You rinse it, reinsert, and carry on. During your period, you don't need anything special—just access to water. Before and after your cycle, you boil it for a few minutes to sterilise.

The downsides? Some people find them uncomfortable initially. And there are situations where they're less practical—if you're travelling somewhere without reliable water access, for instance, or if you have certain medical conditions. They're not for everyone, and that's fine.

Reusable Pads: Familiar Format, Zero Waste

If the internal aspect of cups isn't for you, reusable pads offer a more familiar alternative. They work exactly like disposable pads—you wear them, change them, done—but instead of binning them, you wash and reuse.

What They're Made Of

Most reusable pads use layers of absorbent fabric: organic cotton, bamboo, or microfibre, with a waterproof backing. They fasten with poppers or clips and can absorb as much as a super-plus tampon.

A good quality cloth pad should last 2-4 years, depending on how often you use it and how you care for it. Compared to buying disposables every month, the economics work out brilliantly over time.

Brands Worth Knowing

DAME makes popular reusable pads that are widely available. The quality is consistently good, and they offer various sizes for different flow levels. WUKA, known primarily for period pants, also makes reusable pads worth considering.

For organic options, Natracare offers organic cotton pads that are better for the environment than conventional disposables, even if they're not fully reusable—a good stepping stone if you're not ready for the full switch.

The Practical Reality

I'll be honest: the washing aspect put me off for ages. The idea of rinsing blood from fabric felt like unnecessary effort.

Actually, it's fine. You rinse them in cold water (hot water sets stains), then throw them in with your regular laundry. Some people keep a small wet bag for used pads when they're out and about. The whole process takes perhaps thirty seconds more than throwing something in the bin.

What I didn't love about my first month using reusable pads: figuring out how many I needed. I significantly underestimated. Plan for about 6-8 pads if you want to get through a cycle without doing mid-cycle laundry.

Period Pants: The Beginner-Friendly Option

If I were recommending one sustainable period product to someone completely new to all this, I'd probably say period pants. They're the easiest transition because they feel almost exactly like normal underwear.

Period pants have built-in absorbent layers and leak-proof protection. You wear them instead of (or alongside) other products, then wash and wear again. Good ones can handle two to three tampons' worth of flow.

UK Brand Options

WUKA is a British brand that consistently tests well. They use GOTS-certified organic cotton and offer sizes from XXS to 6XL, including youth sizes. Prices range from around £9-22 per pair, which adds up initially but saves money long-term.

A well-designed period underwear should last around two years with proper care. Given that many people already replace underwear that frequently, the investment makes sense.

Who They're Best For

Period pants for teens are particularly worth mentioning. For young people just starting their periods, reusable underwear removes a lot of the stress around leaks and disposal. Several UK schools are now recommending or even providing period pants as part of their sustainability initiatives.

They're also brilliant as backup protection. Many people use period pants alongside a cup or tampon for peace of mind on heavier days. The combination of cup plus pants for overnight is genuinely game-changing—no midnight anxiety about leaking.

The Catch

Period pants require proper washing to maintain their absorbency. Cold rinse first, then machine wash at 30-40°C, and air dry when possible. The heat from tumble dryers can damage the waterproof layer over time.

And yes, they're an upfront investment. Building a rotation of 5-7 pairs for a full cycle costs £50-150. But spread that over two years of use, and the per-period cost drops dramatically compared to disposables.

Organic Disposables: The Stepping Stone

Not everyone can or wants to use reusables. Medical conditions, living situations, personal preference—there are many valid reasons to stick with disposables. But even within disposables, there are better and worse options.

Organic period care products use 100% organic cotton instead of synthetic materials. They're free from chlorine bleach, dyes, and fragrances. And crucially, brands like &SISTERS by Mooncup make products that actually biodegrade.

Mainstream "organic cotton topsheet" pads often still contain plastic super-absorbent polymers that never break down. &SISTERS' pads and tampons contain no plastic at all—they biodegrade faster than a banana, which is rather satisfying to know.

Where to Find Them

&SISTERS products are available at Asda, Boots, Ocado, and other UK retailers. Kind Organic, FLO, and Yoni are other brands making genuinely plastic-free disposables available in UK supermarkets.

These cost more than conventional disposables—roughly 20-40% more, depending on the product. But they're priced similarly to "premium" disposable brands that offer no environmental benefit at all.

Menstrual Discs: The Newer Alternative

Menstrual discs sit in a different position to cups—higher up, near the cervix—and some people find them more comfortable as a result. They've gained popularity in the UK recently, though they're still less common than cups.

The reusable versions work on the same principle as cups: collect, remove, clean, reinsert. A menstrual disc can typically be worn for up to 12 hours and lasts for years.

I tried discs after struggling initially with cups, and honestly, they worked better for my anatomy. Bodies vary, and what suits one person might not suit another. This is why having options matters.

The Cost Comparison

Let's talk money, because sustainability shouldn't require wealth.

Over a decade of menstruating:

Disposable pads/tampons: Approximately £1,300 (at £130/year)

Menstrual cup: £20-40 (replacing once or twice over ten years)

Reusable pads (rotating set): £80-120 (replacing every 3-4 years)

Period pants (rotating set): £150-250 (replacing every 2-3 years)

Organic disposables: Approximately £1,560-1,820 (20-40% more than conventional)

The upfront costs of reusables are higher, but the long-term savings are substantial. Many local councils now offer subsidised period products, including reusables, through various schemes. Worth checking what's available in your area.

Making the Switch: Practical Tips

After three years of experimenting, here's what I'd tell my past self:

Start Alongside, Not Instead

Don't throw out your disposables on day one. Use your new reusable product alongside a pad or liner while you learn how it works. This removes the fear of leaking and lets you build confidence gradually.

Try Multiple Options

I wasted months assuming cups weren't for me before discovering that different brands fit differently. The Mooncup works brilliantly for some people; others prefer softer cups or discs. If one product doesn't work, try another before dismissing the whole category.

Be Patient with Yourself

I know some of you are thinking this all sounds like a lot of faff. And you're not entirely wrong—there is a learning curve with any new system. But honestly, after the first few cycles, it becomes automatic. The "effort" becomes negligible.

Consider Your Flow

Heavier flows might benefit from cup-plus-pants combinations. Lighter days might only need period pants alone. Products for heavy bleeding exist in sustainable versions too—you don't have to sacrifice protection for principle.

The Bigger Picture

Switching to sustainable period care won't single-handedly solve climate change. I'm aware of that. But here's the thing: small changes genuinely do add up.

If every menstruating person in the UK switched from disposables to reusables, we'd eliminate roughly 22,907 tonnes of waste annually and avoid about 7,900 tonnes of CO2 equivalent. That's not nothing.

And there's something else, harder to quantify. Using sustainable products made me think differently about periods generally—less as a monthly inconvenience to hide and more as a normal bodily function worth managing thoughtfully. That shift in perspective has been unexpectedly valuable.

Finding Products

Grocefully tracks period care products across UK supermarkets, including sustainable options. You can compare prices on everything from organic tampons to period pants and find where &SISTERS by Mooncup, WUKA, DAME, and other sustainable brands are available near you.

The lovely thing about the current market is that options exist for every preference and budget. Whether you go all-in on a menstrual cup or simply switch to organic disposables, every small change helps.

And if you're still unsure? Start with one pack of reusable liners for lighter days. See how you feel. Nobody's grading your sustainability efforts—this isn't a competition. It's about finding what works for your life while doing a bit less harm along the way.

My period drawer now contains a Mooncup, three pairs of WUKA pants, and a single pack of organic liners for emergencies. Three years ago, that sentence would have baffled me. Change happens gradually, and that's absolutely fine.
