Our commitment
Sustainable Growth Partnership is committed to delivering a high standard of service. If something falls short of your expectations, we want to know so we can put it right and learn from the experience.
Informal resolution
Before making a formal complaint, we encourage you to contact us directly. Many concerns can be resolved quickly through a conversation. Please email hello@sustainablegrowthpartnership.com or speak to the person you have been working with.
Formal complaints process
Stage 1: Initial review
If informal resolution is not possible, you can submit a formal complaint in writing to hello@sustainablegrowthpartnership.com. We will acknowledge your complaint within 3 working days and aim to provide a full response within 10 working days. If we need more time due to the complexity of the issue, we will let you know.
Stage 2: Escalation
If you are not satisfied with the outcome of Stage 1, you can request an escalation. A senior partner will review the complaint, the investigation and the response. We aim to provide a Stage 2 response within 15 working days.
Stage 3: Final review
If you remain dissatisfied after Stage 2, the matter will be reviewed by Paul McColgan, Founder and Managing Partner, who will make a final decision on the appropriate resolution.
