I would imagine that you'll also have to sign the declaration that you have indeed installed the spec you have given to the Assessor with the usual responsibilites that go along with such declarations..
So - if my house which was built in the 80's is fully insulated (cavity wall etc.) plus I have underfloor insualtion but no receipts or pics of when it was installed.
Since you do not do an intrusive assessment - and I cannot prove it was installed therefore I get a worse BER rating??
The whole thing is not very good.
How could one be an expert after 5 days of a course?
I spent weeks working with u-values, many years ago, and there is a bit in it.
Ok they use software.
The real joke is no one checks on the work of the builder.
I have encountered houses which were passed by engineers for loans, and had no insulation in the attic. There should be at least 12 inches there i think.
However the idea is good
It is way too expensive for a ber cert at present, 300 seems to be the price they charge, my feeling would be it should cost no more than 100.
Sorry ber guys, a 5 day course just is not good enough.
as regards the electrical controls is the heating system ,no one checks to see if they are even wired up.
Forgive me but you've lost me here, I thought that was exactly what the BER was for?It is NOT a specific measurement of energy usage in a specific dwelling...

Why cant buildings be rated by experiment - as in :
- Heat inside of building to 20C ( for example ) above ambient ( dont want to do this in summer ! )
- Turn off heat source
- Measure amount of time that it takes for temperature to fall by 10C ( for example ) above ambient
With this information a thermal time constant for the building can be computed
with a simple data logger it would be possible to monitor many rooms individually and so establish locations of 'warm' and 'cold' rooms
