Written by Chris Briggs

Using a water butt comes with many benefits. It not only provides you with an ideal source of water for your plants, but also reduces your carbon footprint and could even save you money.

A water butt is a very simple device but an incredibly useful one. By connecting a water butt to the downpipe of your house, you can easily store the rainwater that gathers in your drainpipes and use it to water your plants amongst other things.

Features to consider when buying a water butt include –

  • Its size – Size is always going to be an important considering when buying a water butt. Some hold much more water than others, so you should think about how much you’re likely to use and choose accordingly.
  • Materials used – The majority of water butts are made from plastic, which is ideal since it’s easy to clean and copes with harsh weather well. If you prefer though, there are models that are made from other materials, including wood, stone and clay.
  • Style and colour – Your water butt will be something that’s going to be outside your house for a long time, so even if it’s not on display, you still want to be sure that you’re happy with its appearance.

We’ve rated some of the UK’s best water butts, looking at their key features as well as their pros and cons, helping you to make an informed decision.

Best Pick: Rainsaver Mini 100L Double Kit

An extremely well-made, high-capacity duel tank

Our best pick is the Rainsaver Mini 100L Double Kit. As you can tell from the product name, you get two tanks for your money, each being able to hold 100 litres of water.

You get stands for both units included as well as a rain diverter kit, which means you have everything you need to get it set up and start using it.

Despite their large capacity, these water butts have a nice, compact design and wouldn’t look out of place in your garden.

The included instructions are very easy to follow and unlike a lot of other water butts, they come pre-drilled, so you don’t need to drill your own holes to use them. One kit connects to the other very easily, meaning that when they’re set up, they’ll both fill without any extra work required.

Overall, this is an excellent product and would be ideal if you’re looking to save money on your water bill and have an ideal source of water for your plants.

A practical and affordable solution

This product is very similar in its design to the Rainsaver Mini, being a dark green colour and having a sleek design. It’s also able to hold 100 litres of water and is made from recycled plastic.

In addition to the water butt itself, you also get the stand and diverter kit included. The compact design means this would be ideal for smaller gardens, while still giving you a plentiful supply of rainwater.

The included rain diverter fits most UK standard downpipes and the instructions included are clear and easy-to-follow. This would also be suitable for use with sheds and greenhouses, providing there is guttering and a downpipe to connect it to.

Pros

Sankey 150L Beehive Water Butt

A quirky and unique garden water storage solution

If you’re looking for a water butt that’s unique looking, then the Sankey 150L Beehive Water Butt certainly fits the bill. Shaped like a beehive and with a ceramic appearance to the exterior, it would fit in well in most gardens, especially if you have a lot of stone or ceramic plant pots.

It holds 150 litres of water and is very easy to collect from, with a tap at the base of the unit.  It’s quite easy to set up, although you will need to drill your own hole at the top to connect it.

While it comes with the lid and tap, unfortunately, this model doesn’t come with a diverter kit included, so you will need to buy it separately to connect it to your downpipe and start using it. Also, the matching base has now been discontinued, although you can purchase other bases that fit well.

Overall, it would make a good choice of water butt if you’re looking for something that will fit in well in your garden and provide a good amount of water.

The Benefits of Owning a Water Butt

Owning a water butt comes with some unique benefits. These include –

Easy to fit

Water butts are very easy to set up and don’t really require any special DIY skills. You also don’t need to worry about providing power as you do with a lot of other gardening equipment. 

Suitable for most gardens

A lot of gardening equipment requires you to have a decent-sized garden. This isn’t a problem with a water butt since you’re able to use them even in smaller gardens, providing there is a downpipe to connect it to.

You can also get water butts in many different shapes and sizes, so if you’re looking for something that’s less conspicuous that won’t take up too much space, this won’t be a problem.

A convenient supply of water

The convenience of having a plentiful supply of rainwater to use in your garden is something you’ll wonder how you did without once you get used to having it there. Getting water from a water butt is incredibly easy and the fact that it’s already outdoors saves you from having to keep making trips in and out of the house.

Rainwater is ideal for plants

Another great thing about having a water butt is that it provides you with plenty of rainwater to use on your plants. Rainwater is ideal for plants since it’s free of any chemicals that are in tap water and because it’s at an ideal pH level, being slightly acidic.

Save money

If you’re on a water meter, then recycling rainwater is a great way to save money. The initial investment in a water butt is far outweighed by what you could save in the long term, especially during the summer months when you need to water your plants more often.

Eco-friendly

Using a water butt is a great way to reduce your carbon footprint. Getting water from a tap, it first needs to be treated and pumped, which requires a lot of energy. Making use of a water butt is a much more environmentally friendly way of getting water to use for your garden.

How To Fit A Water Butt

The first thing you need to do is position your water butt so it’s close enough to the downpipe of your house. The water butt shouldn’t be any further than 50cm from the downpipe. You should also screw the provided tap into the hole at the base of the unit.

Once the water butt is in position, you then need to drill a hole in the top of it using a hole saw. Some water butts come pre-drilled, so you can skip this step if that’s the case.  After you’ve drilled the hole you should attach the hose connecter to it.

You’ll now need to remove a section of your downpipe so it can be attached to your water butt. Mark a section of the downpipe that’s level with the hole you drilled in the water butt. The size of the section you need to cut will vary depending on the model, so be sure to check the instructions that came with your water butt.

After you’ve cut the section from your downpipe, you may need to cut the diverter lid, so it fits your downpipe. Then attach the connector pipe to the downpipe, making sure it’s level with the hole at the top of the water butt.

The final step is to cut the pipe so it’s the right length and then attach the water butt to the downpipe.

Once your water butt is set up, all you need to do is use the tap at the base to get water and providing it’s fitted properly, it should last you for many years.
