A 10kVA generator is one of the most popular sizes for both residential and commercial backup power. Compact yet powerful, these sets are widely used to protect homes, offices, retail units, workshops, farms, and construction sites from power outages. For many customers, a 10kVA generator provides the perfect balance between affordability, efficiency, and performance.
Most 10kVA generators are diesel-powered, which makes them reliable and cost-effective for longer running times. Soundproof (canopied) models like the SDMO Diesel 10000E Silence are available for quieter operation, ideal for urban or residential environments, while open-frame sets are often chosen for industrial or site use.
A 10kVA standby generator can support a wide range of applications – from keeping essential household appliances and central heating systems running, to powering tills, lighting, refrigeration, and IT equipment in small businesses. Many customers also choose to fit an Automatic Transfer Switch (ATS), allowing the generator to switch on automatically when mains power fails.
At Generator Warehouse, we not only supply competitively priced 10kVA generators, but we also offer professional installation, nationwide delivery, and expert after-sales support. Our experienced team can help you size your generator correctly, advise on fuel options, and ensure you have the right setup to keep your home or business protected.

What can a 10 kVA generator power?
It powers small sites, shops, offices, homes and outdoor events, running lighting, power tools, tills, refrigeration and heating, delivering about 8 kW of continuous power for that duty.
How long can a 10 kVA generator run on a full tank?
The runtime of a 10 kVA generator depends on factors like fuel tank size, load, and fuel type. Typically, a 10 kVA diesel generator with a full tank can run for about 8 to 12 hours at 75% load. However, this can vary based on specific models and conditions. Regular maintenance, such as checking fuel levels and ensuring filters are clean, can help maintain optimal runtime.
Can a 10 kVA generator power an entire home?
A 10 kVA generator can power most small to medium-sized homes, especially if the home’s electrical load is carefully managed. It can support essential circuits, including lighting, heating, air conditioning, and appliances like refrigerators and water heaters. However, for larger homes with more demanding appliances, it’s crucial to calculate the total load to avoid overloading the generator.
How much does a 10 kVA generator cost?
New sets this size typically run about £3,000 to £8,000 ex VAT, depending on engine brand, canopy and options such as a transfer switch. Most are built to order, so enquire for a firm quote.
Do I need professional installation for my 10kVA generator?
Yes. While some smaller portable units can be plug-and-play, most 10kVA standby generators require professional installation. This includes electrical connection, positioning, and in some cases, the addition of an Automatic Transfer Switch (ATS) to switch power automatically during an outage. Generator Warehouse can arrange installation services nationwide.
Can Generator Warehouse help me choose the right 10kVA generator?
Absolutely. Our team has years of experience supplying generators for homes, businesses, and industry. We’ll assess your power requirements and recommend the best option for your budget and application.
What fuel type is best for a 10kVA generator?
Diesel is the most common choice for standby use due to fuel efficiency and longevity. Petrol and LPG options are available for certain applications, but diesel remains the most cost-effective for long-term use.
How noisy is a 10kVA generator?
Noise levels vary depending on whether you choose an open set or a sound-attenuated canopy. Most modern enclosed 10kVA generators run at around 65–70 dB(A) at 7m, making them suitable for residential and commercial settings.
What after-sales support do you provide?
Generator Warehouse offers full after-sales support, including servicing, spare parts, and technical advice. We also provide ongoing maintenance packages to keep your generator reliable year after year.
How many kW is a 10 kVA generator?
About 8 kW at prime rating. Multiply the kVA by a 0.8 power factor, so 10 becomes roughly 8 kW, with about 9 kW available on standby.
How many amps does a 10 kVA generator give?
Around 14 amps per phase on a 400V three phase supply. These sizes come in single or three phase, so check which your site needs. As a single phase 230V unit the current is higher, about 43 amps. Always size against your real load and starting currents.
How much fuel does a 10 kVA generator use per hour?
Roughly 1 to 2 litres an hour depending on load, and less at part load. Sizing to your true demand keeps fuel down.
