Crested Gecko Care Guide UK — Complete Setup, Diet & Costs (2026)

The crested gecko is one of the best beginner reptiles for UK keepers. Originally from New Caledonia, these small arboreal lizards thrive at room temperature, eat a convenient powdered diet, and require relatively modest enclosure setups. If you are considering your first reptile or looking for a low-maintenance exotic pet, the crested gecko (Correlophus ciliatus) deserves serious consideration.

This comprehensive UK care guide covers everything from enclosure setup and heating costs to diet, handling, health, and where to find specialist vets. All advice follows RSPCA and Royal Veterinary College guidelines, with UK-specific costs and supplier information throughout.

Why Crested Geckos Are Ideal for UK Keepers

Crested geckos (Correlophus ciliatus) were thought extinct until rediscovered in New Caledonia in 1994. Since then, they have become one of the UK's most popular pet reptiles — and with good reason.

Key advantages for UK owners:

• Room temperature friendly: They thrive at 22-26°C, which many UK homes maintain naturally for much of the year. This means significantly lower heating costs than species like bearded dragons.
• No live food required: Crested geckos can live entirely on a powdered complete diet mixed with water. This is a major selling point for keepers who are squeamish about handling live insects.
• Compact enclosure: A vertical vivarium takes up less floor space than a horizontal setup.
• Long lifespan: 15-20 years with proper care, giving you a genuine long-term companion.
• Beginner-friendly: Rated as a beginner species by the RSPCA and most UK reptile specialists.

However, crested geckos are not zero-maintenance. They need consistent humidity (60-80%), a properly set up vivarium, and regular misting. They are also nocturnal/crepuscular, so you will see most activity in the evening and at night.

Enclosure Setup and Size Requirements

Crested geckos are arboreal — they climb rather than walk. This means they need a tall vivarium, not a long one. This is the most important distinction from terrestrial reptiles like leopard geckos.

Minimum enclosure sizes:

• Juvenile (under 6 months): 30×30×45cm — smaller spaces help them find food easily
• Sub-adult (6-12 months): 45×45×60cm
• Adult (12+ months): 60×45×90cm (recommended) or 45×45×60cm (absolute minimum)

Glass vs mesh vivariums:

Glass terrariums with front-opening doors (such as Exo Terra or ReptiZoo) are the best choice for UK keepers because they retain humidity far better than mesh enclosures. The UK's naturally drier indoor air (especially with central heating) makes humidity control a challenge with screen-top enclosures.

Essential decor and furnishings:

• Climbing branches — cork bark, bamboo poles, or manzanita branches
• Live or artificial plants — pothos, bromeliads, and ficus provide cover and boost humidity
• Feeding ledge — mounted high in the enclosure where geckos naturally feed
• Hides — at least two: one high, one low
• Substrate — coconut fibre (coir), bioactive soil mix, or paper towels for juveniles

A bioactive setup using live plants, springtails, and isopods creates a self-cleaning ecosystem that many UK keepers find reduces long-term maintenance.

Temperature and Heating in the UK Climate

One of the biggest advantages of crested geckos for UK keepers is their modest temperature requirements.

Target temperatures:

• Daytime warm end: 24-26°C
• Daytime cool end: 20-22°C
• Night drop: 18-21°C

Critical: Temperatures above 29°C are dangerous and can be lethal. During UK heatwaves (increasingly common), you may need to actively cool the vivarium rather than heat it. Move the enclosure away from direct sunlight and use a small fan to circulate air.

Heating in winter:

From October to March, most UK homes with central heating will keep rooms above 18°C. If your house drops below this at night, consider:

• A low-wattage ceramic heat emitter (25-50W) connected to a thermostat — never use a heat source without a thermostat
• A heat mat on the side of the vivarium (not underneath for arboreal species)

Always monitor temperatures with a digital thermometer/hygrometer placed at both the warm and cool ends of the vivarium. Dial thermometers are inaccurate — invest in digital.

Humidity and Misting

Humidity is the single most important environmental factor for crested gecko health. Getting this wrong is the most common cause of health issues in UK-kept cresties.

Target humidity:

• Daytime: 50-60% (allow some drying out)
• Evening/night: 70-80% (after misting)
• Never below 40% for extended periods

How to maintain humidity in UK homes:

1. Hand misting with a pressure spray bottle — mist heavily in the evening and lightly in the morning. Your gecko will drink water droplets from leaves and glass.
2. Automatic misting systems — worthwhile if you travel or find manual misting difficult.
3. Live plants — pothos, ferns, and bromeliads naturally increase ambient humidity.
4. Substrate choice — coconut coir retains moisture well without going mouldy.
5. Partial glass top — if using a screen-top enclosure, cover 50-75% with glass or cling film to trap moisture.

UK winter challenge: Central heating dries indoor air significantly. You may need to mist 2-3 times daily from November to March. A room humidifier near (not in) the vivarium can help stabilise ambient humidity.

Lighting and UVB

Crested geckos are crepuscular (active at dawn and dusk) and were historically kept without UVB lighting. However, modern guidance from the Royal Veterinary College and the RSPCA now recommends low-level UVB for improved calcium metabolism and overall welfare.

Recommended lighting setup:

• UVB tube: 2-5% shade-dwelling T8 or compact UVB (e.g., Arcadia ShadeDweller or Zoo Med 5.0 Mini Compact)
• Photoperiod: 12 hours on, 12 hours off (use a timer)
• Placement: Ensure the gecko can choose to be within 15-20cm of the UVB source or retreat away from it

LED ambient lighting can supplement the UVB to create a natural day-night cycle, which benefits your gecko's circadian rhythm. Avoid strong, bright lighting — crested geckos prefer dim conditions.

Diet and Feeding Schedule

Diet is where crested geckos truly shine as beginner pets. Unlike most reptiles, they can thrive on a complete powdered diet mixed with water — no live insects required.

Complete powdered diets (recommended brands):

• Pangea Crested Gecko Diet — widely considered the best. Multiple flavours available.
• Repashy Crested Gecko MRP — another excellent option with strong UK availability.

Mix the powder with water to a thick smoothie consistency and offer in an elevated feeding dish (ledge-mounted). Replace uneaten food every 24-48 hours.

Live food (optional but beneficial):

Offering appropriately sized crickets or dubia roaches 1-2 times per week provides enrichment and extra protein. Always dust live insects with:

• Calcium powder (without D3) at every feeding
• Calcium with D3 once per week if no UVB is provided
• Multivitamin powder once per fortnight

🛒 Shop Calcium+D3 Supplement on Amazon UK

Feeding schedule:

• Juveniles (under 12 months): Powdered diet every day; insects 2-3 times per week
• Adults (12+ months): Powdered diet every other day; insects 1-2 times per week

Fresh water should always be available in a shallow dish, though most crested geckos prefer to drink water droplets from misting.

Handling and Temperament

Crested geckos are generally docile and tolerate handling well, making them suitable for older children and adults. However, there are important considerations.

Handling tips:

• Wait 2 weeks after bringing your gecko home before attempting to handle it — let it settle.
• Start with 5-minute sessions, building up to 10-15 minutes over a few weeks.
• Handle in the evening when your gecko is naturally more alert.
• Use a hand-walking technique — let the gecko walk from hand to hand rather than gripping it.
• Never grab the tail — crested geckos can drop their tails (autotomy) and they do not regrow. A tailless gecko is healthy but it is a permanent change.

Temperament notes:

Juveniles are typically jumpier and more flighty than adults. Adult crested geckos (18+ months) are usually calm and enjoy climbing on their keeper. Every gecko has a different personality — some love being held, others prefer to be left alone.

Health and Common Issues

With proper care, crested geckos are robust animals. However, UK keepers should watch for these common health issues:

1. Stuck shed (dysecdysis)

The most common problem, usually caused by low humidity. Signs include retained skin on toes, tail tip, or around the eyes. Prevention: maintain 60-80% humidity and provide a humid hide.

2. Metabolic bone disease (MBD)

Caused by insufficient calcium or vitamin D3. Signs include wobbly walking, soft jaw, and kinked tail. Prevention: calcium supplementation and low-level UVB lighting. See our comprehensive MBD prevention guide.

3. Dehydration

Especially common in UK winter when central heating dries the air. Signs include sunken eyes, wrinkled skin, and lethargy. Prevention: regular misting and a water dish.

4. Tail loss

While not a disease, tail loss from stress, rough handling, or being grabbed is permanent. Tailless crested geckos ("frog-butts") are perfectly healthy and can live a full life.

5. Respiratory infections

Caused by consistently poor ventilation with high humidity (stagnant, damp air). Signs include wheezing, mucus around the mouth, and open-mouth breathing. This requires immediate veterinary attention.

When to see a vet:

Any signs of lethargy, loss of appetite lasting more than 2 weeks, difficulty shedding, breathing issues, or visible injuries warrant a visit to an exotic vet. Register with an RCVS-verified exotic vet before you need one — emergencies happen.

Legal Status in the UK

Crested geckos are fully legal to keep in the UK with no licence or permit required.

• Dangerous Wild Animals Act 1976: Crested geckos are NOT listed. No DWA licence needed.
• CITES: Captive-bred crested geckos have no CITES restrictions for domestic ownership.
• Local councils: No local authority restrictions apply to crested geckos.
• Renting: Check your tenancy agreement — some landlords restrict pets, including reptiles.

For a full overview of UK exotic pet legislation, see our UK exotic pet legal guide. If you are interested in species that DO require a licence, read our DWA licence guide.

Under the Animal Welfare Act 2006, you have a legal duty to meet your crested gecko's five welfare needs: a suitable environment, a suitable diet, the ability to exhibit normal behaviour, being housed with or apart from other animals as appropriate, and protection from pain, suffering, injury, and disease.

Where to Buy Crested Geckos in the UK

Recommended sources:

• Specialist reptile breeders — the best option for healthy, well-socialised animals with known genetics. Look for breeders who provide a feeding record, hatch date, and photos of the parents.
• UK reptile expos — events like Kempton Park Reptile Expo and Doncaster Reptile Show have hundreds of breeders under one roof.
• Reptile rescue centres — consider adopting. Many crested geckos are surrendered by owners who underestimated the 15-20 year commitment.
• Reptile shops — buy from shops that keep their animals in proper conditions and can demonstrate health and feeding records.

What to look for in a healthy gecko:

• Alert, bright eyes
• Clean vent (no stuck faecal matter)
• Full, plump tail (though tailless geckos are healthy too)
• Active and responsive when gently touched
• No visible stuck shed
• Straight spine and limbs (no kinks suggesting MBD)

Red flags to avoid:

• Lethargy, sunken eyes, visible ribs
• Mucus around nostrils or mouth
• Keeper unable to tell you what diet the gecko eats
• Multiple sick-looking animals in the same enclosure

Always have a vet visit arranged within the first 2 weeks of ownership. Find an RCVS-verified exotic vet in your area.
