when did epcs come into force for rental properties?
1 october 2008
epcs were introduced in england and wales on 1 august 2007 as part of home information packs (hips) for domestic properties with four or more bedrooms. over time this requirement was extended to smaller properties. when the requirement for hips was removed in may 2010, the requirement for epcs continued. the scheme for hips was extended to encompass three bedroom homes from 10 september 2007. rental properties, which have a certificate valid for 10 years, required on a new tenancy commencing on or after 1 october 2008. they are a result of european union directive 2002/91/ec relating to the energy performance of buildings, as transposed into british law by the housing act 2004 and the energy performance of buildings (certificates and inspections) (england and wales) regulations 2007 (s.i. 2007/991).

contrary to these empirical results, there has been a multitude of studies where epcs or epfs have been found in seabirds. perhaps the most surprising epfs have been found in the procellariiformess because all members of this order only lay one egg per year and some do not even breed every year. waved albatross show high rates (up to 25% of offspring are extra-pair young) of both epcs and epfs and behavioral observations have shown that many of the epcs are forced by the extra-pair male. studies of wandering albatross have shown over 10% of chicks are extra-pair young; an extremely surprising result since adult wandering albatrosses only breed once every other year when successful. similar results were seen in black-browed ("thalassarche melanophris") and grey-headed albatrosses ("t. chrysostoma") nesting on south georgia island. epfs have also been shown in antarctic petrels. perhaps the most unexpected result was when epcs and epfs were documented in two burrow-nestings procellariids, namely the short-tailed shearwater ("puffinus tenuirostris") and cory's shearwater ("calonectris diomedea borealis"). in the short-tailed shearwater, epfs occur because the female would have to leave her burrow to solicit an epc. in the cory's shearwater population from vila islet, santa maria island, azores, strong competition for nestign cavities/burrows may explain the occurrence of epcs and epfs, with small males facing higher risks of cuckoldry than large ones
