The consumer unit is in a kitchen base cupboard, I live in a semi and it’s on the internal/attached side of the house. All concrete floors, so the only way out is behind the cupboards, to the kitchen wall, one hole to drill, then clip to the exterior wall around to the charge point. I think from the consumer unit to the wall is about 3 metres, then to go around the house to charge point is maybe 13 or 14 metres in total run.
As to me not being a qualified electrician, the surveyor who visited was qualified, he said that the only extra work needed was the digging of a small trench and installation of the charging post.
We then decided not to go that way and just have a standard wall charger with a longer cable ( which we paid for, just under £100 I think).
It was only at this point that a second invoice came saying they needed to dig another trench near the back door…..we explained that they didn’t…….they agreed but then decided that passing the cable behind the base cupboards was a ” complex cable route” involving £160 of extra work.
The route from the consumer unit to the exterior wall has always been the same, it has only become a costly extra item after we declined the first two quotes.
The first two invoices itemised every step off the job, digging of trenches, removing of spoil, making good etc……not a single mention of the “complex route from consumer unit”.
