I have recently completed a rather nice website for an energy grant firm based in Bingley.
If you need a new boiler you will have to satisfy some criteria but you may be entitled to a FREE grant.
Criteria often include:
-not in council accommodation
-boiler over 10 years old
-receiving low-income benefits of some sort e.g. child tax
To see if you qualify go to the website and call them.
Hope it works out!
