The Common Problems With Camper Vans

Dec 27, 2025

Dreaming of van life until the rain starts dripping inside? Short answer: the most common problems with camper vans are mechanical issues, limited space, and damp—especially in the UK. From clever storage fixes to reliable Campervan Conversion Kits, keep reading to avoid costly mistakes and enjoy the journey.

Habitation and Living Area Faults

Issues inside the living area are some of the most frequent problems faced by camper van owners. They can also be among the most expensive if left unchecked.

Damp and Water Ingress: The Most Costly UK Issue

The British climate makes damp and condensation a major concern.
Poor sealing, leaking roofs, or inadequate ventilation often lead to water ingress.

Over time, this can cause mould, unpleasant smells, and structural damage.
Proper insulation and good airflow are essential to reduce these risks.

Leisure Battery Failure and Electrical Gremlins

Electrical issues are common, particularly with leisure batteries.
Battery failure, loose connections, or inconsistent charging can affect lighting and appliances.

These problems are more likely if regular checks are missed.
Cold weather and long periods of storage can also accelerate battery wear.

Gas Appliance Malfunctions (Fridge, Hob, and Heating)

Gas-powered appliances can develop faults over time.
Fridges, hobs, and heaters may become inefficient or unreliable without proper servicing.

Poor maintenance can also introduce safety risks.
Routine inspections help ensure appliances operate safely and efficiently.

Mechanical and Base Vehicle Reliability Issues

Beyond the living space, the base vehicle itself can present reliability concerns.
These issues often depend on age, mileage, and overall weight.

Tyre Blowouts and Weight-Related Suspension Wear

Camper vans often run close to their maximum weight limits.
This increases stress on tyres and suspension components.

Uneven loading can accelerate wear and raise the risk of blowouts.
Regular tyre checks and correct weight distribution are essential.

Engine Overheating and DPF Issues in Modern Diesel Vans

Modern diesel vans can suffer from overheating or DPF issues.
This is especially common on short journeys where engines do not reach optimal temperatures.

Over time, this can reduce performance and increase repair costs.
Longer drives help keep systems working as intended.

Gearbox and Clutch Wear on Older Conversions

Older conversions often experience gearbox and clutch wear.
The added weight of the conversion places extra strain on drivetrain components.

This wear tends to develop gradually.
Early warning signs should not be ignored.

Seasonal and Storage Problems for UK Camper Owners

Seasonal changes introduce a different set of challenges.
These are particularly relevant during long periods of storage.

Winterisation Risks: Frozen Pipes and Cracked Pumps

Cold temperatures can cause serious damage to water systems.
Pipes, pumps, and tanks are all vulnerable during freezing conditions.

The Importance of “Draining Down” Before the First Frost

Failing to drain water systems before winter can lead to cracked pipes and pumps.
This damage is often expensive and avoidable.

Draining down removes water that could freeze and expand.
It is one of the most important winter preparation steps.

Condensation and Mould Growth During Winter Storage

Poor ventilation during winter storage encourages condensation.
This can lead to mould growth on walls, upholstery, and soft furnishings.

Left untreated, it may cause long-term damage.
Regular airflow helps reduce moisture build-up.

Pests and Rodent Damage to Internal Wiring

Stored camper vans can attract rodents seeking warmth.
Mice can chew wiring, insulation, and interior materials.

This type of damage is often discovered too late.
Preventative measures are key.

Tips for Keeping Mice Out of Your Conversion Over Winter

Sealing entry points helps reduce access.
Removing food sources is equally important.

Deterrents and regular checks also lower the risk.
A little preparation can prevent costly repairs.

Practical Solutions and Preventative Maintenance

Routine maintenance is the most effective way to reduce camper van problems.
It also extends the lifespan of both the vehicle and the conversion.

The Essential Annual Habitation Check

An annual habitation check identifies issues early.
This includes damp, gas safety, and electrical systems.

Catching problems early prevents more serious damage.
It also improves safety and reliability.

Why an AWS-Approved Service is Vital for Warranty and Safety

AWS-approved services follow recognised industry standards.
This protects warranties and ensures work is completed correctly.

It also provides peace of mind for owners.
Safety should never be compromised.

Professional Gas and Electric Safety Certification

Certified gas and electrical inspections are essential.
They confirm appliances are operating safely.

These checks are particularly important in older vans.
They also support insurance and resale value.

DIY Maintenance Checklist: Seals, Fluids, and Tyres

Simple routine checks make a big difference.
Inspect seals, fluid levels, and tyre condition regularly.

Ventilation should also be monitored.
These small steps help prevent many common camper van problems.
