Is the loft vented?

The loft is habitable space and ventilated accordingly.

Are the eves vents left intact?

Above the insulation, from front to rear, there is soffit ventilation, 3
ridge vents supported by cross ventilation at the apex and then ventilation
at the rear of the dormer to the soffit. There is at least 5cm to the
ventilation channels. In addition, the sarking is breathable membrane.
