Fish & Koi Cremation in the United Kingdom: what to know
If you're looking for fish cremation in the United Kingdom, start by freezing your fish in a sealed bag. That takes the time pressure off. Then ask your vet or a nearby pet crematorium whether they accept fish, what they'd return for its size and what the total will be in writing. The city pages below add local weather, prices and rules.
Fish are among the most widely kept pets in the United Kingdom, in indoor tanks and garden ponds alike. When one dies, the size of the fish decides most of the plan: a large koi suits private cremation, while a small tank fish often suits a burial, a planter or communal cremation. Below you'll find prices, local rules and every United Kingdom city we cover.
We cover 40 communities in the United Kingdom, from London, Birmingham and Leeds to smaller towns.

How we calculated this
The sum of our per-city estimates for the 40 communities in the United Kingdom on this site: each city's population ÷ national average household size × the national share of households with a fish. Households with several pets count once.

Local attitudes to cremation
With about 83.0%[1] of people cremated, cremation is firmly part of local life in the United Kingdom. Families who keep ashes at home for a parent often feel the same about a long-lived pet, and a koi that has been in the family for twenty years is no exception. If you want your fish home in a small urn beside the pond or on a shelf, you'll find plenty of people here who understand exactly why.

Paying for a fish's goodbye in the United Kingdom
Most UK owners, 67%[2], have their pet cremated, and that can include a much-loved fish. In the United Kingdom, your vet will normally have an arrangement with one crematorium, but you're free to contact another directly. For a fish, ask for their smallest-pet individual price, their communal price and whether a very small fish can have its ashes returned at all.
The UK keeps a lot of fish: 13%[3] of households have an indoor tank and 11%[4] a pond with fish. Yet 89%[5] of people who bought a pet cremation didn't compare providers at all. For a koi or a large goldfish in the United Kingdom, a quick call to an independent pet crematorium as well as your vet can save you money on exactly the same individual cremation.

Burial, scattering and release rules in the United Kingdom
Ashes from a fish are mostly bone mineral, and scattering them is rarely regulated on your own land. Tipping them into a pond that still holds fish can cloud the water, so many keepers scatter around the edge instead. Public lakes, rivers and parks are a different matter: the body that manages them can set its own rules. Here's what applies in the United Kingdom.
The UK is a nation of pond keepers: 11%[4] of households have an outdoor pond with fish. In England you need permission to put fish into rivers, lakes and many ponds connected to them, so never release unwanted fish. Following the CMA's review, it's reasonable to ask any vet or pet crematorium for a written small-pet price list, and to ask what they'd return for a fish.
A calm plan for a fish's aftercare
- Remove the fish from the pond or tank promptly, and with no delay at all if it's warm out.
- Count your stock and look for a cause: a heron, a pump failure, a hot still night or a sudden water problem.
- Fix the water first: add aeration, do a partial water change if readings are off and hold off feeding for a day.
- Freeze the fish you lost, each one in its own sealed bag if you want them cremated separately.
- Decide whether you want ashes back. When you don't, a communal cremation or a burial at a good distance from the pond is a simple, kind choice.
- Ask for a written quote with collection, the cremation itself and the container itemized.
- Mark the loss your own way: a stone at the pond's edge, a new water plant or an entry in your log.
Memorials that suit a fish
A fish's memorial doesn't have to be at home. Some families donate to a local aquarium society, a school science club or a river cleanup group in their fish's name. It's a quiet way of turning a small loss into something useful for the next generation of fish keepers in the United Kingdom.

Questions people ask
How many communities do you cover in the United Kingdom?
We currently have local fish aftercare guides for 40 communities in the United Kingdom, including London, Birmingham and Leeds. Each page covers local weather and timing, prices, rules for burial and scattering, and how to find a provider that accepts fish.
What's the cheapest respectful goodbye for a fish in the United Kingdom?
A garden or planter burial costs almost nothing and gives you a place to visit. If you'd rather not bury, ask your vet whether they include small pets in a communal cremation, usually the lowest-cost cremation available. A photo or plant memorial needs no ash at all.
How much does fish cremation cost in the United Kingdom?
A fish nearly always falls in the smallest weight band, so expect the provider's minimum price for a small pet. Communal cremation is cheaper and returns no ashes. Home collection, urns and keepsakes add to the total. Ask for an itemized written quote, and ask what they'd return for your fish's size before paying for a private cremation.
Can I bury a fish in my garden in the United Kingdom?
Usually yes, on land you own, with sensible care: wrap the fish in paper or cotton and keep well away from ponds, streams and wells. Local rules can be stricter, and landlords may object. A large planter with a new plant is a good alternative.
Is it legal to flush or release a fish in the United Kingdom?
Releasing live fish into the wild is restricted in many places because non-native fish can spread disease and harm native species. Flushing a dead fish isn't a good idea either, as not all wastewater is fully treated. Freeze the fish and choose a burial or cremation instead.
Can I scatter my koi's ashes in a lake or river in the United Kingdom?
It depends on who manages the water, and some public waters require permission. Scattering around your own pond, in the garden rather than into the water, avoids the question and keeps the memorial close. If you use a public place, choose a quiet spot and check the rules first.
