Because if you do you might want to write a letter to your MP (or take a trip to Barton Moss).
"Ministers admit they are looking at overhauling trespass laws to make it easier for energy companies to explore for shale gas"
.....
"Under current law, companies need permission from all the landowners beneath whose land they drill. Case law shows they would otherwise be committing trespass. If a landowner refused permission, the company would have to take them to court, which would decide whether to award drilling rights and how much compensation should be paid."
In order to allow companies to drill horizontal laterals of up to 2 miles long from a single fracking well head the government is seeking to change the law. So if you are within a potential shale producing area then this maybe of interest to you.

Only one well has been fracked using high volume slick water fracking in the UK - see www.frackfreebalcombe.co.uk/page61.php - That was in 2011 at Preese Hall in Lancashire, It caused an earthquake which resulted in minor damage to property.
The map from the Department of Energy and Climate Change here shows the blue areas which are potential shale development areas:

Gas may or may not get cheaper (probably not) but your home certainly will.
