Image one is a possible site of some sort of Impact damage?
Image two is more interesting? in that if you copy, paste then Zoom in as far as I can see the Soldier course has at some time in the past has dropped, the different colour of the mortar directly above the Soldier Course is the give away? that and the very small difference between the bottom line of Soldier course brick and the bed joint on the main wall which is not in-line?
I may be wrong[not an un-common occurrence?] but the second to fifth Soldier in from the left has it appears dropped a tiny amount since the re-pointing as described above?
As well noted above, Valuation Surveyors are only interested in one thing, that is to protect their Professional Indemnity Insurances, the result is at times very, very, VERY conservative advice and Information.
Yes at some time in the future, a lintel MAY? have to be retro-fitted? BUT? as noted above the insertion of Helibar will assist greatly assist in slowing / stopping movement above the Soldier Course.
Big problem with Helibar is that the insertion of this form of repair is very visible because of the different mortar Colour, the only way around mortar colour differentiation [which will not be seen by some valuation Surveyor who then SCREAMS "Subsidence" ] to further protect his Professional Indemnity Insurance, it is worthy of consideration to re-point an area of the brickwork to mask the insertion of the Helibar repair?
As an aside there is nothing at all whatsoever in the two images above that give any cause for concern, and the [with respect] limited damage seen has not been occasioned by Subsidence.
