Additional Information

Thorough Equipment Testing for Reliability

Keeping a site powered requires reliable equipment that won’t fail when it’s needed most. That’s why Thermaright tests all generators before delivery, making sure each unit arrives in full working order. Whether it’s for an event, a construction project, or emergency power backup, properly tested equipment means fewer interruptions and a safe, smooth-running service.

Our testing process includes:

Load testing – Ensuring the generator delivers the expected power output under demand.
Fuel efficiency checks – Making sure the unit provides a steady running time without excess consumption.
Electrical safety inspections – Verifying that the generator operates within industry control standards.
Operational testing – Checking all systems, including start-up, oil levels, and operating temperature.

With rigorous inspections before hire, you can be confident that your temporary power solution is dependable from the moment it arrives.

Choosing the Right Generator Size for Your Project

Selecting the correct generator size is key to keeping your site powered efficiently. Thermaright offers a range of generators, from small portable units to high-capacity diesel generators for larger projects.

Common options include;

10kVA Generators – Ideal for tools, lighting, and small business backup applications.
50kVA to 100kVA Generators – A solid choice for mid-sized projects, including construction sites and industrial locations.
1000kVA and Above – Suitable for city infrastructure, manufacturing plants, and major commercial applications.

If you’re unsure what size you require, our team can assess your power requirements and provide expert advice.

Cost-Effective Generator Hire vs Buying

Purchasing a generator outright may not always be the best choice, especially for businesses that only need temporary power. Hiring a generator through Thermaright is a cost-effective solution, eliminating the need for large upfront investments.

Here’s why generator hire makes financial sense:

No Maintenance Costs – We handle all servicing, ensuring the equipment stays in top condition.
Flexible Upgrades – If your power requirements change, you can easily switch to a larger or smaller generator.
No Storage Hassle – Once your project is finished, simply return the unit—no need for long-term storage.

For businesses in North London, our generator hire service gives you access to high-performance diesel generators at a fraction of the price of buying.
