Green Deal for a Vaillant boiler?

Hello all

Reposting this here as was advised it's more appropriate than the in my home thread.

We've recently moved into a new house that we're slowly renovating. Amongst other things, we want to replace the current water tank and old boiler with a combination boiler (so that we can one day use the cupboard that currently houses the water tank as an ensuite shower cubicle).

We're hoping that we might get £1500 towards this through the Green Deal (£1000 towards the boiler and recoflue, + £500 because we moved in within last twelve months). We're looking at Vaillant boilers, and they also offer £100 cash back if you go ahead (which would cover the cost of the assessment facilitated through them).

I'm fairly confident the assessor would recommend a new boiler as ours is so old, but I'm wondering if they would allow us to a) switch to a combination boiler and b) choose a bigger capacity boiler than the house currently needs (because we might add another bathroom in a few years time)? ie. does anyone know if the Green Deal will only cover new boilers that are equivalent in type and capacity to the ones they replace, or is there flexibility?

Also it would be really interesting to hear any experiences of the Vaillant Green Deal offering (I'm assuming they're just putting me in touch with another company for the assessment rather than doing it themselves).

Thanks very much!
