Save 15% on Water Butt Kits This August: Why Now Is the Time to Start Saving Rainwater
This summer has given gardens across the UK a pretty clear reminder of something we can easily take for granted: water is a precious resource.
After weeks of hot, dry weather, lawns have turned brown, flower beds have needed extra watering and gardeners have been watching the sky hoping for rain.
And now that the rain has started to return, there is a simple question worth asking:
What are you going to do with it?
Rather than allowing valuable rainwater to run straight off your roof and into the drains, installing a water butt gives you the opportunity to capture, store and reuse rainwater in your own garden.
And this August, there is an even better reason to get started.

If you've been thinking about installing a water butt but haven't got around to it, this could be the perfect time.
Because while this summer's weather may eventually pass, the wider challenge around water isn't going away.
The UK is facing a changing water landscape
It's easy to think of the UK as a country where water is plentiful because we are so familiar with rain.
But rainfall isn't necessarily falling where and when we need it.
The Environment Agency explains that climate change is contributing to longer, hotter summers and more intense rainfall in winter, increasing the likelihood of both drought and flooding events.
The UK's National Framework for Water Resources 2025 goes further, highlighting the combination of hotter, drier summers, changing rainfall patterns, population growth and increasing demand for water as significant pressures on future water resources.
That means the way we use water at home and in our gardens matters.
A water butt isn't going to solve the UK's water-resource challenges on its own. But collectively, using rainwater more intelligently is one small, practical step households can take to reduce their reliance on treated mains water for everyday garden watering.
And unlike mains water, rainwater is falling freely from the sky.
Why not make use of it?
Why installing a water butt now makes sense
You might think that the best time to buy a water butt is when the forecast is full of rain.
Actually, installing one before the next big rainfall is the smarter approach.
Once your water butt is connected to your downpipe, it can start collecting rain whenever it arrives.
That means the next shower, overnight downpour or autumn rainfall can go towards filling your garden water storage rather than simply disappearing into the drainage system.
And after the dry summer we've experienced, having stored water available can make a real difference when your plants need it.
A water butt gives you your own garden water supply
Rainwater collected from your roof can be used for many everyday gardening jobs, including:
- Watering flowers and borders
- Watering vegetables and fruit
- Keeping containers and hanging baskets hydrated
- Watering lawns and newly planted areas
- Supporting plants through future dry spells
- General garden maintenance
It's a wonderfully simple principle:
Save water when you have it. Use it when you need it.
Rainwater harvesting isn't just for large properties
When people hear the phrase rainwater harvesting, they sometimes imagine large underground tanks, complicated plumbing and expensive systems.
It doesn't have to be that way.
A domestic water butt is one of the simplest forms of rainwater harvesting.
Rain falls onto your roof, travels through your guttering and downpipe, and can be diverted into a storage container ready to use in your garden.
And that's where the Rainwater Terrace modular water butt system is designed to make things even more flexible.
Instead of being limited to one fixed-size container, the modular design allows you to build a system around your available space and water-storage requirements.
You can start with a smaller system and increase your storage capacity as your garden or rainwater needs grow.
Why saving rainwater matters for the environment
There is another important reason to think about rainwater collection beyond simply keeping your plants alive.
Using water wisely is becoming increasingly important.
The Environment Agency has highlighted the growing pressure on England's water resources and the need to use water more efficiently while building long-term resilience. It also identifies capturing, storing and using more water as part of the approaches needed to address future water challenges.
Using collected rainwater for appropriate garden tasks means you don't always need to turn on the tap to water your plants.
It is a small change, but it's one that can become part of a much more sustainable approach to gardening.
And there is something rather satisfying about watering your garden with water that fell from the sky, collected at your own home and was saved for exactly when you needed it.
Don't wait for the next dry spell
One of the biggest mistakes we can make is thinking about water conservation only when there is a drought.
By then, it's too late to start collecting the rain that has already fallen.
The better approach is to prepare before you need the water.
The UK Government's current water-resource planning recognises that building resilience needs to happen ahead of future pressures rather than simply reacting when a drought occurs.
A water butt is a straightforward way for households and gardeners to take action themselves.
Install it now.
Connect it to your downpipe.
Let the weather do the rest.
Then, when the next dry spell arrives, you'll already have water stored and ready to use.
🌧️ The rain is back. Make every drop count.
After such a hot and dry summer, seeing rain again might not seem particularly exciting.
But for gardeners, it is a valuable opportunity.
Every rainfall is an opportunity to refill your water storage.
So if you've been considering buying a water butt, expanding your garden's rainwater storage or starting your own rainwater harvesting system, now is a great time to do it.
