Best Bird Cages UK: Spacious, Secure Homes Compared

How we chose these bird cages: lengths, bar gaps, trays, perches and feeders come from the makers’ published specifications and live UK retail listings, checked October 2026. We have not tested the products ourselves. A cage is a night roost and a short-stay room, not a life sentence. The RSPCA is blunt that birds need at least six hours of safe free flight every day, so buy length you can keep uncluttered and plan the room, not only the box.

How Large Should a Bird Cage Be?

Measure the bird’s flying wingspan, then use the RSPCA cage sizes: at least twice that span in height, width and depth if the bird spends most of the day inside, or one and a half times if it is out for most of the day. A cockatiel wingspan is often more than twice the body length, so a pretty 40 cm cube fails even as a night box. Horizontal length matters more than a tall, thin tower, because birds fly across, not up a ladder. The Vision Home for Birds Tall is 74.9 x 38.1 x 91.9 cm; the Ferplast Sonia XL is 99.5 x 53 x 108 cm inside a 97.5 x 51 x 101 cm living space; the Yaheetech Wide Flight Cage is 77.5 x 46.5 x 46 cm of sideways room. Colony budgies, cockatiels and lovebirds may share if you add 5 or 10 percent per extra bird after the first two, by weight. Large non-colony parrots must not share one cage; give each its own room and see the parrot cages page for heavier bar stock. Budgie keepers who want species-specific bar gaps should also read budgie cages. If you can build or buy a garden flight, step up to the bird aviaries page rather than stacking ever taller indoor towers.

What Bar Spacing and Perches Does a Cage Need?

Bar spacing has to be smaller than the bird’s head and large enough that a toe does not wedge. Ferplast quotes 10 mm on the Rekord 2, 9.8 mm on Sonia XL, and 18.5 mm on Sonia XL’s net pitch in one listing line, so read the figure that matches the species: 10 mm-class gaps suit canaries, finches and budgies; a cockatiel needs a wider, stronger grid. Savic Noah at 80 x 50 x 70 cm is sold for cockatiels. PawHut’s 46.5 x 35.5 x 92 cm cage uses 0.9 cm spacing. Prevue’s flight kit lists 66 x 35.6 x 57.2 cm with a 1.3 cm class gap. Fit natural wood of mixed diameters so feet do not sit on one dowel all night, and place perches so droppings do not land in bowls. Terracotta perches on the Vision cages are shaped to vary the grip. Leave an empty flight lane down the long side; a swing belongs on the bird swings page and should not block that lane. Cover the back and top of the cage with a cloth so the bird feels a wall behind it, and keep the box off radiators and out of draughts. Indoor-only birds still need UVA and UVB lamps made for birds, with shade, because window glass blocks those rays.

How Do You Clean an Indoor Cage?

Pick a design you will actually empty. Vision cages drop the wire top off a deep base, so you carry the base to a bin instead of fighting a jammed drawer. Ferplast Rekord 2, Sonia XL and Giulietta use removable trays or drawers plus Brava feeders you rotate and fill from outside. Yaheetech and PawHut models use slide-out trays and a grate. Line the tray with paper you can lift daily, wash the grate weekly, and scrub bowls outside the cage. A bird cage cover helps the bird roost, but wash it as often as the tray so dust and mites do not sit in the fabric. Do not mist-clean timber on the Giulietta with solvent; wipe FSC pine with a damp cloth only. Change perches when they glaze. If you keep a water bottle, check the ball valve every day because a blocked bottle is an empty bottle.

How Should You Set Up a New Cage?

Build the room around the cage before the bird arrives, then keep the first week quiet.

1. Assemble the cage away from cookers, ceiling fans and open windows, with the back against a solid wall.
2. Fit mixed-thickness perches at different heights, and leave a clear flight strip along the longest side.
3. Fill bowls from outside where the design allows, and place water where droppings cannot fall in.
4. Let the bird enter from a carrier on its own time; do not chase it into a far corner.
5. Offer the first free-flight session in a closed, mirror-screened room only after the bird eats and perches calmly.
6. Wash the tray that evening and keep a cover for night, washed as often as the paper liner.
