I have a 3 bed house that gets very hot in summer and it's been
suggested an "earth pipe" may be a solution.

How much cooling effet can one expect from an "earth pipe"?

What diameter pipe is suitable? How long does the pipe run need to be?
How deep does it need to be buried?

Are there any websites with further info I can go look at?

Try this:

Also look at this thread:

Google Earth pipe and earth tube on groups and web.

In Germany they spiral a 8-12" pipe around a house foundations.  Easy to do
when building. Pretty common there.

 Humidity can lead to condensation and mold in these pipes.  You need
to be careful.  Mold can kill.

May as well bury hundreds of feet of plastic pipe underground and fill this
loop with water.  Use this to run though a water to air duct mounted heat
exchanger.  Will be easier to bury the small bore plastic pipe rather than
large 8 to 12 inch plastic soil pipes.
