Motorhome Generator Fitting

Heading off-grid in your motorhome, campervan or caravan gives you the freedom to travel without limits – but it also means you need a dependable power supply. At Motorhome Workshop, we specialise in fitting high-quality onboard generators that deliver the comfort and convenience of 240v mains power wherever you park. 

Whether you want to run high-demand appliances or simply enjoy peace of mind on long journeys, a professionally installed generator for motorhomes is a smart and cost-effective solution.

Why Choose an Onboard Motorhome Generator?

Modern travellers rely on a wide range of electrical appliances, from microwaves and kettles to laptops, air conditioning, and hairdryers. A motorhome generator provides a stable, continuous power source capable of handling these higher loads – something that solar panels or leisure batteries alone may not always achieve.

An onboard system also means:

  • Independence from campsite hook-ups
  • Consistent 240v output, even in remote locations
  • Cleaner, quieter operation with many of today’s efficient models
  • Automatic or remote start options for complete convenience

Our generators are specifically designed for mobile environments, offering compact sizes, reliable performance and enhanced fuel efficiency. Whether you’re fitting a generator to a motorhome, upgrading a campervan generator or equipping a caravan for the first time, our team ensures the installation meets the highest safety and functional standards.

Our Range of Motorhome, Campervan & Caravan Generators

We supply and install a wide selection of premium generator systems suitable for motorhomes, campervans and caravans. Each type has its own benefits, and our specialists can guide you towards the model that best fits your travel style and vehicle layout.

LPG Generators

An LPG generator is a popular choice for many motorhome owners thanks to its clean burn, lower running costs and reduced emissions. If you already use an onboard LPG tank for cooking or heating, integrating an LPG generator is simple and efficient. These units also tend to be quieter, making them ideal for extended off-grid stays.

Petrol Generators

Petrol generators remain a reliable and versatile option. They offer excellent power output and are easy to refuel when travelling. If you want strong performance without the need for a diesel system, a petrol generator for campervans or caravans provides a dependable mid-range solution.

Diesel Generators

For vehicles already running on diesel, choosing a diesel motorhome generator ensures maximum efficiency. These systems are robust, long-lasting and ideal for powering energy-hungry appliances. Touring in colder climates or taking long trips? Diesel generators are known for their reliability in challenging conditions.

We have a motorhome generator for sale for almost every requirement, and our technicians are always happy to discuss suitability, noise levels, fuel consumption and installation options.
