    The Benefits of our Diesel Generators

    Our range of diesel generators includes convenient portable options that are an ideal choice for everything from domestic back-up power sources to use on busy workshops and building sites.

    Diesel generators are more economical and efficient than petrol options and ultimately can be cheaper to run. They are often more hardwearing and require less maintenance, and such aspects make them a better option for business and trade users who intend to run them for extended periods.

    There are also different capacities and specifications available. For example, we have silent diesel generators for sale among our selection – units that can provide top performance with minimal sound. If you aren’t sure which model would be right for you, why not check out our generator selection guide to point you in the right direction.

    What are diesel generators used for?

    Small diesel generators for domestic use can supply power in the event of an electrical failure, while industrial models are commonly found on construction sites. In those settings, they can be used to provide lighting to help work continue around the clock, run air conditioning units or power other heavy-duty equipment. Silent generators offer a quieter option on sites where noise pollution needs to be kept to a minimum.

    Why SGS are the go-to for diesel generators in the UK

    All our diesel generators come with a 60-day returns policy and if you order before 4pm there’s next working day delivery in the UK.

    Our diesel generators also come with different warranty options that are detailed on each product page, while our tens of thousands of glowing reviews on Trustpilot show just how much our customers value what we do for them.
