nPower use Vaillant but other installers have access to the 5yr warranty deal; we have offered it for the last 3 yrs.
From my experience you can expect a better standard of installation from BG than nPower, who have only been installing boilers for a short while.
If you get a skilled independent round, rather than one of the nationals, you will be treated to an engineer rather than a salesman.
I expect most customers would rather be guided by an engineering led solution for their requirements rather than sales patter from a fast track training course.
The independents are usually cheaper and have to rely on their installation rather than sales skill.
