Great initiative

The best thing about going through the steps is that it confirms that a lot of what you have done is on the right track, makes you prioritise the small things you have been putting off, and gives you a roadmap and motivation for greater improvements.

Fantastic to get validation for our sustainability efforts

We are pleased to be part of this movement to recognise holiday rental properties that are trying their best to be more sustainable and think about their business and the impact it has on the planet. Thank you Sustonica.

Great idea needs some refinement

Great idea to rate green business practice but the bar was set quite low on the requirements in the test. The assessment process was ok. Some of the criteria did not relate well to the UK standards.
