Frogs can't be bought. The way to get more in the garden is to create the right conditions, and here's how.
What does it look like?
Britain has two native frogs, two toads, and three newt species. The common frog and common toad are the ones most likely to turn up in a garden anywhere in Britain; smooth and palmate newts are also widely distributed. A garden pond may occasionally attract the great crested newt, a scarce, legally protected species.
How to encourage it
A pond is the standard way to bring frogs in: they need somewhere for tadpoles to develop, with at least one side sloping gradually up to dry land so young amphibians can get out (a ramp covered in chicken wire works in a steep-sided pond). Log piles, hedge bottoms, compost heaps and the space under stones or paving slabs all give adult frogs somewhere damp to shelter once they're out of the water. Letting grass grow long along one edge of the pond gives cover for young frogs leaving it. A bog garden, a permanently damp area separate from the pond itself, adds another kind of wet habitat frogs use.
Winter is a separate problem from summer shelter: frogs need somewhere to hibernate that won't freeze or flood, and a log pile or compost heap doesn't always do that job well. A purpose-built hibernaculum, or a simple toad abode tucked into a shady, undisturbed corner, gives them a dedicated overwintering spot rather than leaving them to find one in the open.
Slug pellets, even organic ones, have been shown to harm garden wildlife generally, frogs included by extension, given how much time they spend around the damp ground and vegetation slug pellets are scattered on.

Myths about frogs

“You need to dig a garden pond before frogs will ever show up in your garden.”
A pond is what frogs need to breed in, not what they need to simply turn up. Froglife's own FAQ on attracting amphibians is explicit that a garden without a pond, or without room for one, can still benefit them and still see them using it, so long as there's water nearby for breeding. The Wildlife Trusts describe the same pattern the other way round: once frogs have a pond to breed in, they spend most of their time out of the water, foraging through log piles, long grass and compost heaps.
Our read The confusion is understandable because breeding absolutely does require standing water. But a damp, sheltered garden next to someone else's pond, a ditch or even a boggy patch can host visiting frogs without a pond of its own.
What to do: If a pond isn't possible, build the terrestrial habitat anyway: log piles, long grass, a compost heap and damp shady corners. A pond remains the single best addition for breeding, but its absence doesn't rule frogs out entirely.

- RHS, Garden amphibiansAmphibians need still water such as a pond to mate and lay eggs, but also rely on log piles, hedge bottoms and long grass once out of the water.
“Scooping up frogspawn and moving it to a different pond is a harmless way to help frogs spread to new spots.”
New ponds should be left to be colonised naturally rather than stocked by transferring spawn or tadpoles from elsewhere, because moving spawn between ponds raises the risk of spreading infection and disease, ranavirus among them, along with invasive weeds that can hitch a ride in the water.
What to do: Leave frogspawn where it is. A new pond, especially one with a shallow, planted margin, will usually be found and colonised by frogs on its own within a season or two without any transfers needed.

“Frogs spend winter hibernating buried at the bottom of the garden pond”
Most frogs and toads overwinter on land, not underwater. Froglife, the UK's amphibian and reptile conservation charity, states that frogs and toads normally overwinter in places like compost heaps, amongst dead wood, or under decking, sheds or other objects — it's only some frogs (and occasionally newts) that choose to spend winter at the bottom of a pond, and even then they stay near the oxygen-rich surface layer rather than burying deep into mud.
What to do: Leave sheltered, undisturbed spots on land (log piles, compost heaps, leaf litter, gaps under sheds) as well as a pond — don't assume the pond alone is where your frogs are spending the winter.

“Frogs and toads live mainly on slugs, so a pond alone will sort out a slug problem in the veg patch.”
Slugs are genuinely on the menu, but no institutional source describes them as the main item. RHS describes amphibians generally as feeding on "a wide range of small invertebrates" without singling out slugs. The Wildlife Trusts' profile of the common frog does call it a pond visitor that feasts on slugs and snails, and describes the common toad the same way, while Froglife's garden advice lists slugs alongside insects as a general food source. None of the three quantifies how much of the diet slugs actually make up.
Our read The gap between "slugs are eaten" and "slugs are the main course" matters for expectations. A garden with frogs is likely to see some slug predation, but nothing sourced here supports treating a pond as a standalone slug-control measure.
What to do: Treat frogs and toads as one part of a wider predator community, alongside ground beetles, birds and hedgehogs, rather than a single fix. Avoid slug pellets, which harm the same wildlife that would otherwise help.

Frequently asked questions
Can I buy frogs?
Not usefully: frogs released into a garden with nothing to hold them there simply leave. Creating the right habitat and food source is what actually keeps a population around; see "How to encourage it" above.
How do I know if frogs are actually helping?
Watch the pest population, not the predator count: fewer flea beetle over a few weeks is the real sign, not how many frogs you can spot on a given day.
