London, England
Koi, goldfish and tank fish: the London picture
If you own your home, UK guidance generally allows burying a pet in your own garden, away from water and with enough depth, but that's not an option for most renters or flat dwellers. London's mild, damp climate means a body can be kept cool for a short time at home in a cold room, wrapped in a blanket. For most families, private cremation with ashes returned is the practical choice.
Many Londoners connect their pet with one particular place, whether a sunny patch of back garden, a windowsill above a busy street, or a green space such as Hampstead Heath or a stretch of the Thames path. Scattering ashes on public land usually needs the landowner's permission, and the royal parks and many councils have their own rules. Ask first, or keep the ashes at home and plant something in a pot or garden in your pet's memory.
Prices in London vary more between providers than most people expect, and a fish almost always lands in the lowest weight band. That band has a minimum charge, because running the equipment costs much the same for a four-ounce goldfish as for a ten-pound koi. Ask for a written total that includes collection, the container and any certificate, and compare two quotes before you agree.
London is home to about 8,982,000 people, the largest of the 33 England communities we cover.
Nearby, we also have local pages for Chelsea (2 miles), Kensington (3 miles) and Richmond (8 miles), which can help if your vet or the provider you prefer is based there.

How many fish-owning households London has (estimate)
How we calculated this
8,982,000 ÷ 2.4 = 3,742,500 households; × 13% (fish) = 485,000. Multi-pet homes count once.

13% of UK households keep an indoor fish tank.
83.0%[2]
In 2024, 83.0% of deaths in England & Wales ended in cremation.
10 million[3]
About 10 million US households keep freshwater fish.
3-5% of body weight[4]
Embrace notes cremated remains typically weigh about 3-5% of the pet's original body weight.

What local funeral customs suggest for a pet fish
About 83.0%[2] of people in England are cremated, and pet cremation is correspondingly common. For fish keepers, the practical upshot is that you're unlikely to be the first person to ask a local crematory about a koi. Many will have a clear policy: fish over a certain size cremated privately with ashes returned, very small fish offered communal cremation or a symbolic return. Ask to hear that policy before you book.
That England rate is a human one, published by Federation of Burial and Cremation Authorities (FBCA) death & cremation statistics (2024). We quote it for London only as a pointer to how families here already think about cremation.
Season by season: fish losses in London
Outdoor goodbyes for a fish depend on the weather, but they don't have to happen straight away. Many families in London keep a fish frozen, or keep a larger fish's ashes indoors, until a calm, dry day for a small ceremony by the pond or in the garden. Choose a day that suits the people who loved the fish.
Fish cremation prices for London families
Following its review of vet services, the CMA wants every practice to offer a communal option and set out its prices. That matters, because only 47%[5] of UK cremation buyers recalled being told about a range of options, including communal cremation or home burial. For a fish in London, ask for all three: individual, communal and what the practice would suggest if you'd rather bury at home.
The full price table by size is on our England page, and the services page explains what each option includes.

Rules worth knowing in England
Fish aftercare touches fewer rules than a dog or horse, but a few are worth knowing. Burying on rented land needs the owner's agreement. Scattering ashes into open water can need permission from whoever manages it. And releasing live fish, or pouring out a pond, is illegal in many places because of invasive species. Here's the local picture for England.
The UK is a nation of pond keepers: 11%[7] 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.
The rules that apply across England (home burial, scattering and who oversees pet cremation) are summarized on our England page. London may add its own conditions, so check with the city or county before digging.
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 visiting heron, a pump that stopped, a sultry airless night or a water quality crash.
- Fix the water first: get more air into it, change part of the water if your test readings are wrong and skip feeding for a day.
- Freeze the fish you lost, bagging and sealing them individually if separate cremations are what you'd like.
- 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.
Small memorials for a small life in London
London pets live everywhere from Victorian terraces with narrow back gardens to high-rise flats, and many owners don't drive. Home collection is often the easiest route, especially inside the congestion zone, and most pet crematoria serving London are in the outer boroughs or beyond the M25. When you request options, give your postcode and mention parking, stairs or a lift so the collection can be planned properly.

Questions people ask
Can a provider from a neighbouring town collect from London?
Usually yes. Chelsea is about 2 miles away, Kensington is about 3 miles away and Richmond is about 8 miles away, all inside a normal collection radius. Get the mileage written into the quote so there is no surprise on the day.
Why does the London page quote a human cremation rate?
Because it is the best local signal we have. Federation of Burial and Cremation Authorities (FBCA) death & cremation statistics (2024) reports about 83.0%[2] of England residents are cremated. There is no official pet equivalent, and inventing one would be worse than quoting a real, clearly labelled number.
Where can I bury a fish if I live in an apartment in London?
A large planter on a balcony or windowsill works well for a small fish. Wrap it in paper, bury it in fresh compost and plant something on top. Don't bury pets in public parks or communal gardens without permission. If you'd rather not bury at all, communal cremation through a vet is a simple option.
How many fish households are there in London?
By our estimate, about 485,000 households in London keep fish, based on the national share of households with fish and the local population. So you're far from alone. Fish losses happen in many homes every year, and it's normal to want a proper goodbye.
What should I do with the other fish after one dies?
Remove the dead fish quickly, then test the water for ammonia, nitrite, pH and temperature. Check the filter, pump and heater. If readings are off, do a partial water change and hold off feeding for a day. Watch the others closely for a week. If more fish look unwell, a vet who sees fish can examine a freshly chilled body.
Are there other fish keepers in London I could ask for advice?
Plenty. By our estimate, London has around 485,000 fish-keeping households, which is why aquarium shops, pond societies and local online groups tend to be lively. Members can tell you which vets see fish, which crematories have handled one and what they paid. They're also good people to talk to about a loss, because they understand why a fish mattered.
