That is a good point. We certainly do not anticipate that assessors would be able to go door to door, give an assessment and then have people sign up there and then. There will be a cooling-off period. We considered in Committee whether an assessor could also be a representative of a commercial organisation or company. We came to the view that that could be possible, but that there would have to be a clear distinction between the roles they performed. An assessor would have to make their assessment on a uniform format and to the same standard right across the industry, so that it could be taken to other providers of green deal services. We would encourage all consumers to get a competitive quote before committing. If consumers wish to go with the first person who knocks on their door or the first person whom they invite in to make an assessment, it is obviously their right to do so. However, we are building in apparatus to ensure that that is not encouraged.
