Here are the criteria for inclusion off the CAMRA website:
"Criteria for Inclusion
The focus is entirely on interiors and what is authentically old. The pub should retain a reasonable amount of genuinely historic internal fabric and/or sufficient of the layout for the historic plan-form to be appreciated and understood. The emphasis is on pre-1939 interiors, although post-war examples might occasionally be considered if they have particular merit / quality fittings. The interior should be little altered in the past 40 years.
Applying the Criteria
When considering a pub for inclusion in a Regional Inventory of Historic Pubs Interiors / Real Heritage Pub guide there are two aspects to look at: -
a) Historic plan. Is it largely intact? ** A two room pub that previously had 3 rooms could pass this part of the criteria.
b) Specific features. The greater the amount of original features – like the bar counter, bar-back, wall-tiles, screens, original toilets and so on – the better. If all that survives is a couple of fixed benches and a bit of match-board wall panelling in a largely opened up pub, then inclusion cannot be justified since they are very commonplace items found in large numbers. But add in a largely intact servery and only a slightly opened-up plan and it probably can be. A specific interesting feature or two might justify inclusion, but would have to be of real significance for inclusion of an otherwise wrecked interior."
I would have thought local branches would have sniffed out any interiors worthy of inclusion, but perhaps that is a bit naiive?
