Cockatiel Care Guide UK — Cage Size, Diet, Costs and Daily Care (2026)

A cockatiel needs a cage at least 96 cm high, wide and deep, six or more hours of safe flight a day, a pellet-based diet and a vet who sees birds, and it can live 15 years or more. This cockatiel care guide for UK homes turns that into a plan you can follow, with real sizes in centimetres, costs in pounds and the rules that apply where you live.

If you have read conflicting advice, you are not alone. Seed-only diets and small "starter" cages are still sold everywhere, so many owners only learn the better way later. The good news is that the RSPCA, the Royal Veterinary College (RVC) and GOV.UK publish clear guidance, and everything below is checked against it.

Is a cockatiel right for your home?

Cockatiels are small, gentle members of the cockatoo family from inland Australia. An adult measures about 30 cm from head to tail tip and weighs roughly 80–100 g. The RVC puts a typical captive lifespan at 10–15 years, and the MSD Veterinary Manual notes some reach 20.

That long life is the first thing to plan for. A cockatiel bought today could still need you in 2040, through house moves, new jobs and holidays. Ask yourself who would care for them if you could not.

They are flock birds that call, whistle and need company every day. They also shed a fine feather dust that settles on furniture, so expect a little extra cleaning. Our cockatiel species overview gives a shorter summary to share with your household.

Before you commit, look up exotic vets near you and phone one or two. Ask whether they see cockatiels and what happens out of hours. Finding that answer now is far easier than in an emergency.

Cockatiel cage size UK: how big is big enough?

The RSPCA's bird housing guidance sizes cages by wingspan. If your bird spends most of its time in the cage, its height, width and depth should all be at least twice its wingspan. Defra's licensing guidance gives a cockatiel's flying wingspan as 48 cm, so that means at least 96 cm in every direction.

If your cockatiel is out of the cage for most of the day, the RSPCA minimum drops to one and a half times the wingspan: 72 cm each way. Bigger is always better, and the RVC suggests using the cage mainly at night or when nobody is home.

Choose bars spaced no more than 1.3 cm apart, so your bird cannot push its head or a wing through. Look for a zinc-free cage, because the RVC reports that zinc poisoning from cages and toy fixings is increasingly common.

Swap the plastic or dowel perches that come with most cages for natural wooden branches of different thicknesses. The RVC says they prevent most of the foot injuries it sees and keep nails worn down. Skip sandpaper perch covers, which simply rub the feet sore.

Place the cage with its back against a solid wall, away from radiators, fires, draughts and direct sun. Never put it in the kitchen.

Food and water bowls belong where droppings will not fall into them, at perch height. Wash them every day in hot, soapy water and dry them well, as the MSD Veterinary Manual advises. A screw-fixed stainless steel bowl is easy to lift out and hard for a clever beak to tip over.

One cockatiel or two?

In the wild, cockatiels live in large flocks. The RVC recommends pairing a cockatiel with another of its own species for lifelong company, and the RSPCA lists cockatiels among birds that can live together in social groups.

A pair still needs your time, but they keep each other company while you are at work. Some hand-reared birds bond strongly with people, so ask the breeder or rescue about your bird's history first.

Never put a new bird straight in with an existing one. The Association of Avian Veterinarians advises a vet check and keeping a newcomer separate for at least six weeks, with no shared bowls or perches. Introduce them gradually afterwards, in a cage big enough for both birds to move away from each other.

If one bird is chased away from food or perches, separate them and ask your vet or an experienced keeper for help. A second bird is not a cure for calling or feather plucking, so book a vet check if behaviour changes suddenly.

What do cockatiels eat? A UK feeding plan

Seed mixes are the traditional cockatiel food, but on their own they are unbalanced. The MSD Veterinary Manual explains that seeds lack vitamin A, key proteins and calcium, which can lead to obesity, liver disease and breathing problems.

The RVC's cockatiel care sheet recommends that a good-quality complete pellet makes up 60–80% of the diet. The rest should be vegetables, a little sprouted seed, and good seed kept for treats and training. The RSPCA's feeding guidance agrees on pellets as the base and says small parrots like cockatiels still need some seed each day, up to a tenth of the diet.

Good vegetables include peas, broccoli, kale, spinach, carrot and sweet potato. Small amounts of washed fruit such as de-seeded apple, grapes, pomegranate or blueberries are fine too. Remove fresh food before it starts to spoil.

Fresh water should always be available, plus a shallow saucer for bathing, changed daily. Cockatiels do not need grit: parrots remove seed husks before swallowing. Do not add vitamins to the drinking water either, because it can put birds off drinking.

Vets do not all agree on the exact split. The Association of Avian Veterinarians warns that some small parrots, cockatiels included, can develop kidney problems on a pellet-only diet, so let your avian vet set the balance for your bird.

Switching from seed to pellets safely

Many cockatiels do not recognise pellets as food at first, so a switch takes patience. The RSPCA says it can take several weeks or even months, and that your avian vet should check your bird is healthy before you start.

The RVC describes a four-week method that works well for stubborn birds:

• Put pellets in the usual food bowl, and a small daily seed ration in a second bowl somewhere new.
• Week 1: one heaped teaspoon of seed a day. Week 2: a rounded teaspoon. Week 3: a level teaspoon. Week 4: half a teaspoon.
• From week 5, seed becomes a treat or training reward only.
• Never mix seed and pellets in one bowl, or your bird will simply pick out the seed.

Cockatiels feed on the ground in the wild. Scattering pellets on a sheet of white paper or a mirror on the cage floor first thing in the morning often gets them interested.

Weigh your bird every morning before food during the switch, on scales that show single grams (see our pick in the weighing section). Droppings may change colour, but the amount should not drop. Never starve your bird into eating pellets. If they lose weight or stop eating, give the old food back at once and call your vet.

Daily flight and a bird-safe room

The RSPCA says cockatiels need at least six hours outside the cage every day, with space to fly freely and safely. Flight is how they exercise, so a large cage on its own is not enough.

Before you open the cage door, run through a quick room check:

• Close windows and outside doors, and switch off ceiling and desk fans.
• Cover or mark large windows and mirrors until your bird learns the room.
• Keep cats and dogs out, however friendly they seem.
• Remove open water, hot drinks, trailing cables and small objects that could be chewed.
• Stay with your bird for the whole session.

If you think your bird has breathed in fumes, move them into fresh air and call a vet immediately. Our emergency guide helps you find out-of-hours contacts. Do not wait for breathing problems to appear.

Cleaning the cage without harming your bird

Change the cage-floor paper daily. It is the easiest way to check your bird's droppings, and it stops dust building up. That matters for you as well: UKHSA advises against letting droppings and feathers accumulate, because dried droppings can spread psittacosis, an infection people can catch from birds.

Cleaning and disinfecting are two different jobs. First remove the dirt with hot soapy water. Then, if you disinfect, use a product made for the purpose at its labelled dilution, on surfaces that are already clean. Move your bird to another room while you work, and let everything dry before it goes back.

F10 Disinfectant Ready to Use comes pre-diluted at 1:250, so there is no mixing. Never spray near your bird, never mix it with other cleaners, and if your vet suspects an infection, ask them for a specific cleaning plan.

Use biocides safely. Always read the label and product information before use.

Light, sleep and temperature in a British home

Indoor birds miss out on natural ultraviolet light, because window glass blocks it. The RSPCA advises a flicker-free bird lamp giving 12% UVA and 2.4% UVB, fitted above the cage so it shines down, as the RVC recommends. Leave part of the cage shaded so your bird can choose, and replace the tube when the maker says.

Sleep matters as much as light. Most pet birds do best with 10–12 hours of quiet darkness a night, according to the Association of Avian Veterinarians. Long days can trigger hormonal behaviour and repeated egg laying, which the MSD Veterinary Manual says is especially common in cockatiels.

Many cockatiel owners describe "night frights": sudden panics in the dark that can injure a wing. A dim night light and a quiet room away from car headlights often help, and any bleeding needs a vet.

You do not need a special temperature for a healthy cockatiel. The MSD Veterinary Manual says birds usually do well at temperatures comfortable for people. In a British winter, the bigger risks are draughts and sudden changes, so keep the cage away from radiators and doors, and have a plan for a heating failure.

Foraging and enrichment: let your cockatiel work for food

Wild cockatiels spend much of the day searching for seeds on the ground. Foraging means letting your bird do the same at home, which keeps them busy and less likely to over-eat or pluck.

The Association of Avian Veterinarians' foraging guide suggests starting simply. Place a favourite piece of food on a sheet of paper. Once your bird takes it confidently, fold the paper over it, then wrap it loosely. If they struggle, make a small hole to show them the way.

Cockatiels are natural ground foragers, so a tray of artificial grass with a few seeds scattered through it works well. Natural seed heads also give them something to strip and search. Count them as part of the daily seed allowance, not as extra food.

Weigh your cockatiel every week

Birds hide illness well, and weight loss is often the first sign. The RSPCA recommends weighing your parrot every week on digital kitchen scales, at the same time of day, and writing it down.

The Association of Avian Veterinarians says a change of about 10% either way needs a vet visit. For a typical 90 g cockatiel, that is only 9 g, which is why scales that read single grams matter.

Most birds will not sit still on a flat scale. Stand a small wooden perch on it, press the tare button so the perch weighs zero, then let your bird step up. Build this into a calm routine with a treat, and stop if it causes distress.

Signs your cockatiel needs a vet

Learn what normal looks like for your bird: their usual voice, appetite, droppings and favourite perches. A noticeable change deserves attention, even if it seems small.

While you arrange help, keep your bird warm (around 27–29°C), quiet and in a dimly lit carrier. The MSD Veterinary Manual's list of illness signs is a useful reference to keep on your phone.

A few problems are especially common in cockatiels:

• Chronic egg laying and egg binding. The RVC names cockatiels as one of the species most prone to laying egg after egg, which drains a hen's calcium. A hen that strains, sits on the floor or bobs her tail may be egg-bound, and that is an emergency.
• Respiratory disease. Sneezing, nasal discharge and swollen eyes can follow a seed-heavy diet low in vitamin A, among other causes.
• Zinc and lead poisoning. Old cages, galvanised wire and some toy fixings are common sources.
• Psittacosis. Cockatiels can carry this bacterial infection without looking ill. In people, UKHSA guidance describes flu-like symptoms 1–4 weeks after exposure. If you feel unwell, tell your GP that you keep birds.

If something is wrong out of hours, use our 24/7 emergency vet finder and phone ahead so the clinic can prepare.

Finding an avian vet and getting there safely

Not every practice is comfortable with birds, so choose one before you need it. Our guide to finding an avian vet in the UK lists the questions to ask. Then search our vet directory and phone your shortlist to confirm they treat cockatiels.

The RVC recommends a health check every year, because problems are easier to treat when found early. A new bird should be checked before it joins your household. At a typical visit, the vet weighs your bird and examines them from beak to toe.

For the journey, the RSPCA suggests a plastic carrier, or a wire one partly covered with a pale towel, with a perch fixed near the floor. Keep your bird warm and in near-darkness, warm the car first in cold weather and drive smoothly. Practise short sessions in the carrier at home, so the first trip is not the vet visit.

UK rules: registration and where your bird comes from

Owning a cockatiel is legal in every part of the UK, and cockatiels are not listed under CITES. Registration with the government depends on where you live and how you house your bird:

• England and Wales: you must register within one month unless your cockatiel is fully housed indoors with no access to the open air. Taking your bird outdoors at any time, even for exercise, means you must register. Vet visits do not count. See the GOV.UK registration guidance for England and Wales.
• Scotland: the Scottish Kept Bird Register is free. Cockatiels are exempt if kept indoors with no outdoor access, or in a fully enclosed outdoor structure.
• Northern Ireland: DAERA exempts pet birds kept in the owner's home. Ask DAERA if you plan an outdoor aviary.

If you also keep chickens or other birds that are not exempt, you will need to register. Bird flu measures change through the year, so check the latest bird flu situation before taking your bird to shows or gatherings. Our UK bird ownership guide covers the wider rules.

Whatever the paperwork, the Animal Welfare Act 2006 (and its equivalents in Scotland and Northern Ireland) makes you legally responsible for meeting your bird's needs. Buy from a reputable breeder or rescue, and keep any paperwork you are given.

How much does a cockatiel cost in the UK?

Prices vary by region and seller, so treat these as a starting point. We checked every figure below in October 2026 against named UK sources: rescue fee pages, private adverts, retailer listings, published vet price lists and an insurer's own price page.

The cage is where budgets go wrong. Many products sold as "cockatiel cages" are far smaller than the RSPCA minimum of 72 cm each way (96 cm if your bird is caged most of the day), so check the measurements rather than the label. Large parrot cages that do meet it often have bars too wide for a cockatiel, and cheap garden aviaries tend to use galvanised mesh, which the RVC advises against. A walk-in indoor flight cage is usually the safest fit.

The start-up figure does not include perches, toys, a carrier or scales. The yearly figure covers routine costs only. If your bird becomes ill, investigations at a specialist referral centre can cost £650–£950, according to the RVC's published prices, which is why the RVC recommends insurance.

Vet fees differ a lot between practices. Since 2026, the Competition and Markets Authority requires UK vets to publish standard price lists, so ask your chosen practice for theirs before you need it.

Your cockatiel arrival checklist

Before you bring a cockatiel home, make sure you can tick every line:

• Vet: an avian vet chosen, their number and out-of-hours number saved, and a first check booked.
• Cage: at least 96 cm in every direction (or 72 cm if your bird will be out most of the day), set up away from the kitchen.
• Room: a bird-safe flight room and a routine for six or more hours out of the cage.
• Food: the bird's current food, plus pellets and vegetables ready for a gradual switch.
• Equipment: natural perches, steel bowls, a gram scale, a carrier and a UV bird lamp.
• Company: a plan for a second cockatiel, or for plenty of daily time together.
• Paperwork: registration checked for your nation and housing, and a holiday carer lined up.

Use our cockatiel species overview to walk your family through the plan.
