Our turnkey generator installations are convenient and designed exclusively for your site, load requirements, and local conditions. We follow a set process to ensure professionalism and reliability:
Survey & Load Assessment: When our technicians assess your site, we'll evaluate any constraints and look at capacity requirements. This involves performing a full load assessment by analysing your equipment, starting currents, and output.
Generator Specification: Once we establish your load profile, we'll advise a suitable kVA/kW rating based on your current and future needs.
Access Planning: Many Portsmouth sites have restricted access, making it harder to find a suitable placement for your generator. We plan the installation process, factoring in all logistics. This includes planning delivery routes, getting crane access, and understanding lifting requirements.
ATS/MTS Integration: Transfer switches are vital components of your generator, ensuring a seamless transition from mains power to your backup supply. Whether you choose an ATS or MTS, we'll install and configure it for seamless transitions.
Fuel Storage: The most significant issues in storing diesel fuel are maintaining compliance and avoiding degradation. We'll suggest suitable fuel storage tanks and provide testing services if you suspect contamination.
Installation & Commissioning: Once your generator is installed, we'll commission it. This involves verifying that the transfer switch works correctly and running it under load.
Documentation & Final Steps: You'll receive instructions, compliance documents, and commissioning records.
Maintenance Plans: Generators are complex machines that require specialist maintenance. Our customers can access convenient servicing and maintenance packages for durability and reliability.
Generators are an excellent option for homes and businesses in Portsmouth. However, it's not a standard inland site, which means we have to consider multiple factors when installing your genset. These include:
Coastal Exposure: High levels of salt in the air increase the risks of corrosion. We'll assess your site and advise suitable coatings, fixings, and enclosures to ensure operational stability and durability.
Noise Reduction: Portsmouth is a dense residential, commercial, and industrial area. Noise control is usually essential to avoid disruptions and remain compliant. We factor in noise when positioning your generator.
Access Limitations: Controlled zoning on Portsea Island, limited space, and narrow roads all present difficulties. However, we're highly experienced in navigating access restrictions.
Marine & Dockside Locations: If your commercial or industrial site is near a dock, we'll need to plan careful cable routing, earthing, and distribution planning.
Diesel generators can last for decades, but they require regular service and maintenance. Because these machines are complex, many people choose a professional service. With a team of fully qualified engineers, we can swiftly diagnose issues and provide proactive generator repairs.
Our cost-effective generator maintenance services ensure:
Reliable power solutions during power outages
Detailed compliance documentation for insurance and audits
Reduced repair costs
Long-term peace of mind
Coolant, fluid levels, and engine oil checks.
Full filter inspections and replacements when needed.

You can also add load bank testing where necessary.
Our main priority is to keep homes and businesses running and ensure reliable power access. We respond quickly to any issues, and are highly experienced in addressing:
Battery Failures: Standby generators often remain in standby for long periods. Over time, this can increase the risks of battery degradation.
Fuel Quality Issues: Fuel quality issues happen when fuel is unused for long periods or isn't stored correctly.
Corrosion: Portsmouth has high levels of salt in the air, which can increase the risks of corrosion.
Airflow and Cooling Problems: If your generator has restricted airflow or isn't appropriately sited, it can experience airflow and cooling issues.

Yes, we do. While manual changeover systems can be convenient and more affordable, we generally offer automatic transfer switches because they sense when you lose access to your primary electricity supply and remotely activate the generator.
It depends on your location and how you use the generator. Annual services are the standard, but coastal exposure or prior faults with your genset may warrant twice-yearly or more frequent inspections.
Standard checks include battery condition, filters, fluids, control panel and alarm checks, test runs, and fuel analysis. Load assessments are an optional extra.
