Register details with them and you can provide custards with a free boiler providing they meet the affordable warmth criteria. They give you 1500 minus whatever boiler and controls you buy. They deal with the grant side of things.
The remainder is for pipe and sundries and your fee is what's left.
That's my understanding anyway.
It will help the little guys stay afloat and its in the interest of the manufacturers to do this also as The 'firms' rinsing the eco schemes will favour a particular cheap shiddy boiler like the eaga/isar combination
So manufacturers if they want to jeep selling boilers need to make sure the independents keep going and can provide a choice. Undertaking the grant thing in an installer behalf is one such way and imo if all manufacturers follow suit it will be the 'thrown at the wall by monkeys, firms that will suffer
