3kVA Site Transformer Hire London | 240V to 110V Heater Transformer (16A)

What a 3kVA heater transformer is used for

A 3kVA site transformer converts standard 230 to 240V mains power down to 110V, allowing you to run 110V site equipment. It is commonly hired as an add-on when using 110V heaters, air movers, dehumidifiers or site tools in locations that only have standard mains sockets. At Hireload, our 3kVA Site Transformer Hire service is selected to support safe, practical and reliable 110V power conversion for a wide range of temporary site applications.

Typical applications

• 110V fan heaters and temporary heating setups
• 110V drying equipment used on refurb and restoration work
• 110V site tools where 110V is required
• Site cabins and temporary buildings with 110V distribution

Choosing the right transformer

Important notes

• Load matters: do not exceed the transformer rating. If you are unsure, tell us the heater wattage and we will confirm suitability.
• Site setup: use correct 110V connectors and manage cables safely to reduce trip hazards. Hireload can also help you choose the right transformer class for your equipment so your temporary power setup is both safe and suitable for the intended load.
• Return condition: return reasonably clean. Heavy residue may incur a cleaning fee.

Frequently asked questions

What is a site transformer used for?
A site transformer steps down 240V mains power to 110V, which is the mandatory safe voltage for power tools on UK construction sites. You plug the transformer into a standard 240V socket and connect your 110V tools, lights, and equipment to the 110V outlets.

What is the difference between this and the continuous rated version?
This is a standard intermittent rated 3kVA transformer, suitable for typical site tool use where loads cycle on and off during normal work. The continuous rated version is designed for equipment that runs non-stop, such as lighting rigs, heaters, or dehumidifiers.

How many 110V outlets does it have?
The transformer has multiple 110V 16A outlets so you can run several tools and lights from a single unit. Check the combined wattage of everything connected and ensure it stays within the 3kVA rating.

Can I use it at home?
You can use it in a domestic property if you need to run 110V tools from a 240V mains supply. Plug it into a standard 13A socket. This is common for DIY projects where trade-grade 110V tools are being used.

Do I need one if my tools are 240V?
No. A transformer is only needed for 110V tools. If all your equipment runs on 240V, you can plug directly into mains sockets. However, 110V is the safety standard on construction sites and most professional contractors use 110V tools.
