THE UK'S NO. 1 FOR GENERATORS
The Honda EM5500S generator is a powerful and dependable solution for both domestic and light commercial use, delivering a maximum output of 5500W with smooth, stable performance. Built for endurance, reliability, and ease of operation, this generator runs on standard unleaded petrol and features a durable OHV 4-stroke engine known for its legendary Honda dependability. Designed to keep your tools, appliances, and sensitive electronics running safely and efficiently, the EM5500S is ideal for use on job sites, in workshops, at outdoor events, or as a reliable backup power source at home.
With an extended run time of up to 6.5 hours at rated load, the Honda EM5500S is engineered for long-lasting power on a single tank of fuel. Its fuel-efficient engine and generous tank size allow for uninterrupted operation, reducing the need for constant refuelling. The generator also features a Digital Automatic Voltage Regulator (AVR), which delivers consistent voltage regardless of load changes. This level of power stability is essential when operating sensitive devices, such as laptops, diagnostic tools, or lighting systems, ensuring a flicker-free and safe power supply every time.
The EM5500S is designed with convenience in mind. Its durable, powder-coated steel frame offers excellent protection and easy lifting points, while the included wheel kit makes transporting the generator between locations simple and efficient. With multiple output sockets offering both 115V and 230V, you can run a variety of commercial equipment, site tools, or domestic appliances with ease. Whether you're powering 110V tools on a construction site or keeping household essentials running during an outage, the EM5500S adapts to your needs.
For added safety, the generator is equipped with circuit breaker outlets to protect your equipment from short circuits or overloads, and Honda’s Oil Alert® system shuts down the engine automatically if the oil drops below a safe level, preventing costly damage and maintaining long-term engine health. The oil capacity of the unit is 1.1 litres, supporting the engine’s ability to run efficiently over long sessions. Despite its power, the EM5500S remains relatively quiet in operation thanks to Honda’s reduced-noise design, which includes a high-quality muffler and sound-dampening components, making it more pleasant to use for extended periods.
The EM5500S combines Honda’s premium engineering and rugged construction with modern features that enhance safety, performance, and ease of use. Whether you're working in a professional environment or preparing for unexpected power outages at home, this generator offers consistent, high-output performance in a portable and user-friendly package. Backed by a 5-year domestic warranty and a 1-year commercial warranty, the Honda EM5500S stands as a reliable investment in quality, longevity, and peace of mind.
Built for industrial resilience, this generator is housed in a heavy-duty tubular steel frame with anti-vibration mounts and an optional wheel/transport kit. Safety features include oil-alert shutdown, idle control to reduce fuel use at light loads, and thermal overload protection.
Fitted sockets include:
These ensure compatibility with a broad range of equipment used across UK sites and field operations .
This generator is ideally suited for heavy-duty applications such as construction, engineering, event power, agricultural machinery, and home/business standby use. It delivers professional-grade output where clean, reliable electricity is required off-grid or under uncertain power supply conditions.
As per Honda's recommendation we will remove the new generator from the box and start & test, this gives you the confidence that you should not experience any problems when receiving your order. We can also personally deliver your product (mainland England and Wales). Please see options at checkout.
The Honda EM5500S is covered by a 5‑year warranty for domestic use (one year for commercial/professional use*), backed by Honda’s UK authorised dealer network and straightforward access to genuine Honda parts and accessories.
Honda's products are built better to last longer. That's why we can offer you a rock-solid warranty for domestic and professional use on our core range products, covering both parts and labour. The warranty also maintains the same value throughout the warranty period - meaning the last day of cover is exactly the same as the first.
*Subject to domestic/professional use and following the service schedule
The EM5500S can run most medium-to-heavy-duty electrical appliances and tools, including cement mixers, compressors, lighting rigs, welders, fridges, and sensitive electronic equipment. Its 5,000 W rated output makes it ideal for use on construction sites, at outdoor events, or as backup power for homes and businesses.
The EM5500S comes with the following UK socket configuration:
– 1 × 110 V / 16 A
– 1 × 110 V / 32 A

Honda Motor Company Limited is a Japanese public multinational corporation primarily known as a manufacturer of cars, motorcycles and power equipment. Honda is also the world's largest manufacturer of internal combustion engines measured by volume, producing more than 14 million internal combustion engines each year. The company has assembly plants around the globe.
It was back in September 1978 when Honda launched their very first lawn mower in Europe. At that time, standard 2-stroke technology dominated the market, providing noisy, dirty engines that were difficult to maintain. So Honda fitted their lawn mowers with ground-breaking 4-stroke engines; setting new standards of performance, reliability and safety, but they didn’t stop with the engines.
Honda's aim has always been to constantly improve in all areas of design, so they built in hard-wearing durability and long-lasting performance at every stage of the process, from cast iron cylinder sleeves and ball bearings to support the crankshaft, to aerodynamic cutter decks with nylon grass bags for improved airflow and more efficient collection.
For years, Honda have built all their lawn, garden and power equipment around clean 4-stroke engine technology. That’s because they’re committed to making their products as user-friendly, fuel-efficient and reliable as they can, without compromising performance.
Today, Honda have harnessed their design and technology expertise to create a versatile repertoire of lawn, garden and power products from lawn mowers and brush cutters through generators and water pumps to tillers and snow throwers. Their patented Roto-stop feature is their latest benchmark in design, providing complete safety and peace of mind by allowing users to stop their lawn mower blades turning without switching the engine off.
In short, Honda products are quite simply the crème de la crème of garden machinery and power equipment.
