Material Costs, Labour Fees and Time Frame Estimates for Pond Installation


A lot of people are interested in the costs involved in a garden pond installation. This isn’t usually a very easy question to answer but in this article, we hope to provide you with a good idea through the pricing guidelines we present. At the same time, we also hope to provide you with some helpful details on the various types of ponds that are available out there and which ones would fit your home settings best. Ponds and other garden water features are quite popular across the UK with many people choosing to undertake the project, especially during the summer or spring.

Pond Depth

Before getting the pond installation project started, the first important decision you must make is to determine how deep you would want the pond to be. This is essential since this can affect how much the final price is going to be. If this is a pond intended for decoration purposes only, a 0.6-metre depth will be more than enough. If you intend to keep small decorative fishes, make sure that the depth is at least 1 metre. For Koi carps and other types of large fish, make sure that the depth is 1.5 metres. The area where the pond will be installed can also impact the final price.

Also, ponds that are shaped regularly will usually be cheaper compared to those that have a fancier ornamental appearance.

Pond Liner Materials

When it comes to materials for the pond liner, several options are available— all of which are useful as a barrier that will keep the water in once placed onto the dug up hole. You may also go for fibreglass and ready-made liners made of plastic as they are cheaper. Just note that they are generally shallow and are only available at such limited shapes and designs.

You have the choice to go for rubber liners too. These flexible liners have a variety of sizes and shapes available but they are generally more expensive. Note that no matter the type of liner you’ll choose, it’s best to place an underlay right under the liner to make sure that root penetration is prevented. The underlay is also helpful at preventing any damage caused by stones. The underlay is often supplied in rolls of 2-metre width and is designed for easy fitting. 

It just needs to be rolled out around the contours of the pond, while also ensuring that there’s about 20cm of overlap. A knife or scissors can then be used to trim any underlay excess. For flinty soil, it’s best to get as many stones removed first before rolling out the underlay. If you’re going for a rubber liner, you won’t have to worry about restrictions in terms of the pond’s shape or size as it is available in such a wide range of options.  If you want to go the extra mile, bespoke pond liners can be purchased which will be specifically made with your preferred shape, size, design, and dimension in mind.

DIY Prospects

If choosing to dig out the pond DIY, make sure first that the ground is properly levelled. If it isn’t, then steps have to be taken to get it levelled, which would include getting the lower parts built up to ensure the maintenance of the water level. This is backbreaking work though so expect that this is going to cost you not only more time but more funds too if you are to get somebody to do the job for you. Use a string to mark out how you want the pond to be shaped.

A spray could do the trick as well. Then just start digging from the perimeter going inwards. You can then add a marginal shelf where you can add plants later on. Once this is done, the part where the deep water is going to be located will then be excavated until its full depth is achieved.

An important note to remember when excavating, the sides must be gently sloping towards the inside. This Is essential so the soil will not end up collapsing. To keep water from saturating the soil, surrounding the pond, a perimeter trench is always a good idea. Make sure it is dug around the pond’s top area. A pond hose, the flexible type, can be used for this purpose as it would be easy enough to follow the pond’s shape.

Once this is done, the protective underlay follows along with the flexible liner. The gap should be filled with pebbles so there will be a physical barrier between the edge of the water and that of the soil.

Pond Installation Costs

When landscaping a garden by installing a pond, average costs can vary considerably. you do have the choice to go for a pond that would cost a couple or so hundred pounds to one as intricate as costing thousands. Deeper ponds or those that have a number of additional features will generally cost more. It does help to have a good grasp of what you really want ahead of time to prevent unnecessarily spending money on ideas that you’d, later on, scrap for another.

Also, more complex and larger ponds are expected to take longer to complete so it is important to specify with the tradesperson who will be assisting you about their daily rates and the estimates for the work involved. It’s common for tradespeople to charge £200 daily so expect that the number of days added to the completion of a more complex pond is going to have to add to the final costs. Always remember to prioritize the overall quality of work instead of speed especially if rushing things through is only going to cost issues later on.

Among the work that tradespersons can be expected to do include digging a hole, laying the underlay, landscaping the pond and adding any special features that you want to get included. Expect them to do a variety of work when completing the project. Also, there is a very good chance that they might charge you more depending on how varied and complex the work involved is.

Cost Breakdown

Installing an average-sized pond for your garden will likely cost around £3000. Landscaping is already included in the costs. About £1800 will be spent on the materials and the remaining £1200 covers for the tradesman’s fees.
