When you say it has burnt the worktop which has lost some colour, has it gone pale the same as a hot cup can leave a ring mark on tables ect. If this is the case there is a way of getting it out assuming this is a laminated worktop.
The heat from the pan has not actualy burnt the worktop, what has happened is the glue under the laminate has melted and come through the laminate which gives a cloudy look to the colour.
If this is the case you can remove it using Methylated Spirits. It takes some courage to try but it does work. Clear the area to be treated take a cloth and soak it in the meth's ring it out so it is damp and wipe it across the affected area, light one end and let it burn across the area, this will produce a very gentle flame for a very short time, when it burns out leave for a few seconds and you will see a small improvement. Repeat severaral times until mark goes and colour returns.
Prior to trying this make sure you have plenty of ventilation and have your fire extinguisher handy just in case.
If you are worried about doing this, do what i did and get an old bit of laminated wood put a hot cup of bioling water on it so it makes a ring and have a practice first.
I know i am going to get lots of comments about how mad i am but
I have done this several time now for friends and family and it has always worked.
Bite the bullet and have a go.
