Many thanks for your reply. Here are my representations for both fines.

The alleged contravention did not occur because:
As I approached the area in question I was unaware of there being any restrictions in place. Turning left onto Nightingale Grove from Springbank Road the road layout is as such that there is a blue warning sign for heavy goods to the left roadside and the blue warning sign for a prohibitive area behind this is not in clear view as there is overgrown foliage covering the sign. The placement of the heavy goods blue sign also makes it difficult to clearly see the blue warning sign for the restrictive area in time to avoid any contravention.
The only other warning presents itself on Ardmere Road when it is too late to reverse or amend the route, hence unwittingly entering the prohibited route. There is also a large overgrown tree which obscures the signage to the right on Ardmere Road when travelling along Nightingale Road towards Ardmere Road.
Photos are submitted in evidence of foliage covering the blue sign on Nightingale Grove, and the overgrown tree obscuring view into Ardmere whilst travelling along Nightingale Grove.
This signage is inadequate, and in light of the above please cancel the PCN.

The alleged contravention did not occur because:
As I approached the area in question I was unaware of there being any restrictions in place. Turning left onto Fernbrook Crescent from Fernbrook Road the road layout is such that there is a blue prohibitive warning sign to the left roadside that is not in clear view as there is overgrown foliage covering the sign from view turning into Fernbrook Crescent . Due to sign’s proximity of the Fernbrook Road left turn onto Fernbrook Crescent there is then insufficient time to note the blue warning sign once turned onto Fernbrook Crescent.
Turning then right onto Leahurst Road from Fernbrook Crescent leads immediately onto the prohibited route sign on Leahurst Road when it is therefore too late to reverse or amend the route, hence unwittingly entering the prohibited route. There is no other prohibitive route warning clearly visable.
Photos are submitted in evidence of foliage covering the blue sign from view turning left into Fernbrook Crescent from Fernbrook Road.
