Reasonable BER rating?

OneOfThem Stumbled

What would be considered a good BER for older properties (90-110 years), as a rule of thumb?

Supposing full renovation which have emphasised insulation and energy saving features, what could consumers expect from a property?

great question. if it was me: id try to work out the min best reno, but your tryin to get there already - actual comfort & thermal comfort along with the energy saving should rule the decisions. and the age of the house needs to be related to the specifics. give us more info please, and try not to waffle:)

For a house over a hundred years old,

With drylined internal insulated walls throughout
Cold attic that has been well insulated
Insulation between floors
Independent zoned gas heating
Condensing Gas boiler
Predominantly double glazed windows and doors (>80%)
Draught proofed doors.

No additional mod cons such as solar panels, etc.

I would say C3 or C2 for rule of thumb answer . Look here for a more detailed response.

Yup, C2/C3 sounds about right, but if you really need to know, get a BER done. Your spec doesn't give enough information on U values achieved etc.

If getting a BER, it will show lower energy usage if you've kept all details proving that the work was done (details from Architect, Engineer, receipts for work done etc).

The spec you've give sounds almost up to the level of the Appendix C house in TGD L 2005. That would've been in or around a C1:

unless your on the cusp of tipping from one rating level into another, no it wouldnt be worth doing.

draught excluders are standard for most elements bar single glazed windows.
These dont penalise, they help
