Pond cleaning cost

If you have a pond, regular cleaning is a must. Without maintenance, plant life can become overgrown and debris (made up of decomposing organic matter and fish waste) can build up. This can create a sludge, which can give off toxic gases harmful to fish and block light needed for underwater plants. It also looks and smells unpleasant.

In this guide, we’ll look at the average pond cleaning cost, so you can budget for regular pond maintenance.

The average cost of pond cleaning depends on the size and depth of your pond. Also, how long it’s been since your pond was last deep cleaned, or how well you’ve kept on top of weeding and light maintenance. The dirtier the pond, the longer it’ll take to clean.

But on average, a full service will cost around £150 per hour.

Koi pond maintenance costs

Koi carp are beautiful fish, but they can also be a little messier than other kinds of fish. This is because they’re known for rooting up the bottom of the pond, as well as producing lots of waste.

Due to this and the fact that koi ponds need to be deeper than other ponds, cleaning costs can be higher. Expect to pay nearer the top end for an annual service. This makes the average koi pond cleaning cost around £400 per clean. You may also need to have your koi pond deep cleaned more frequently.

How much does a koi pond cost to run?

The cost of running a koi pond will depend on a number of factors, including the size of your pond and the pump you have installed.

For a koi pond, you’ll need to have the pump running 24 hours a day, in order to make sure the filter system is running all the time. The average energy cost for a large koi fish pond using a P8000 pump with one 55w UV bulb is around  £200.75 per year.

If you want to calculate a budget for how much a koi pond costs to run a year, you’ll also need to include the cleaning costs. It’s recommended that you clean your koi pond twice a year – once at the beginning of summer and once in autumn to prepare it for winter. At £400 per clean, on average, that’s a total of £800 per year per year.

There may be other costs to running your koi pond, such as replacing filters, pump repairs, and fish food costs – among others. But as a start, you should budget at least £400 per year for the basic running costs of your koi pond.

What’s involved in pond maintenance?

Pond cleaning is more than just scooping out the accumulated dirt, debris and sediment. It actually involves a long list of tasks to keep your pond in great condition. These include:

  • Setting up a temporary tank and partially draining the pond
  • Carefully removing fish and other wildlife
  • Fully draining the pond
  • Power washing the pond liner
  • Removing debris from the bottom of the pond
  • Trimming plant foliage
  • Cleaning and servicing the filters, pumps and other equipment
  • Checking for leaks
  • Refilling the pond, adding appropriate treatments and testing the water
  • Rehoming the fish and other wildlife, and doing a quick health check to make sure conditions are right

How often will my pond need cleaning?

A full pond clean is recommended every 3-5 years. According to the Royal Horticultural Society, you should consider a pond overhaul every 5 years or so. This is to remove weeds and sediment, while a thorough clean is recommended every 10 years.

Can I clean my pond myself?

Of course, but remember that pond cleaning can be a time-consuming, messy and unpleasant job. There are lots of jobs that need doing, and you’ll need to be careful not to upset the ecosystem of the pond and its fish and plant life. DIY is fine for weeding and light maintenance, but it’s recommended to bring in a pond expert when it comes to deep cleaning.

How long does pond cleaning take?

DIY pond maintenance takes around 15-30 minutes for an average-sized pond, while a thorough deep clean can take up to a full day.
