Do reptiles need UVB lighting in the UK?

Diurnal species such as bearded dragons need UVB for vitamin D3 and calcium metabolism. Replace tubes per manufacturer guidance — output declines before they stop glowing.

Why is my bearded dragon not eating?

Causes include incorrect temperatures, brumation, stress, impaction or illness. Check basking spot with a digital thermometer and contact an exotic vet if appetite does not return.

Do I need a specialist vet for reptiles?

Yes. Find a vet experienced in exotics before you need one. Incorrect husbandry is the leading cause of reptile illness in the UK.

Reptile Care in the UK — Bearded Dragons, Geckos & Snakes

Published 1 June 2026Last updated 25 June 20261 min read

Quick answer

UK pet reptiles need a precise thermogradient, appropriate UVB for diurnal species, correct humidity, and species-specific diet. Register with an exotic vet and never use heat rocks — they cause serious burns.

Heating and lighting

Provide a basking zone and cooler end so your reptile can thermoregulate. Measure with digital thermometers at both ends — dial gauges on tank walls are unreliable.

Bearded dragons — basking ~38–42°C, UVB tube across the vivarium
Leopard geckos — belly heat, hides on warm and cool sides
Corn snakes — appropriate ambient temperature; no UVB required for nocturnal species

Diet by species

Bearded dragons: insects and leafy greens (proportion changes with age). Leopard geckos: live insects gut-loaded with calcium. Snakes: defrosted prey of appropriate size — never live feeding in the UK home environment.

Warning signs

Weight loss, retained shed, diarrhoea, mouth rot, sunken eyes, or open-mouth breathing need a vet check. Metabolic bone disease from poor UVB/calcium is preventable with correct setup.
