Lynn....... if like me you also carry a gas hob kettle, then consider one of these (others are available)
Make sure one of the rings is rated at 1000watts which makes it a low power appliance.
They have the advantage of being more versatile than a kettle
If you are paying for an EHU why use gas?

I also use a domestic kettle if the site supply allows.
Most club and large sites have a 3000watt supply and a domestic kettle will be fine as long as you make sure other heavy use appliances are turned off.
When a supply trips off, the kettle often gets the blame, when infact the kettle would be OK if the total electrical usage did not exceed the supply.
