Payback quotes based on 50% export

[HotSpot]

Hi

I believe the 'approved' method for quoting payback amount and time is using a deemed export of 50% and the other 50% as electrical savings. I'm now considering doing quotes maintaining the deemed 50% export figure for income but an actual export (or electrical savings) of (say) 25% when I know that the consumer actually uses more or less than 50% of the power.

My query is whether modifying the actual electrical savings takes the payback quote outside REAL compliance? In other words, does the official SAP quote have to be based on 50% export AND 50% savings? Hope that makes sense.

The REAL Consumer Code says:

Proposals to consumers must only include estimates of savings, periods of recovery ('payback') or other measures of financial effectiveness based on the consumer's actual energy use. Any assumptions that have been made (for example, of energy prices, interest rates or inflation) must be set out and clearly explained. These estimates should not mislead the consumer in such a way as to affect their economic behaviour.

The EST calculator uses a figure of 25% as assumed in-house consumption.

And British gas solar Pv calcs use 15.44p as basic electricity cost.
