Ecology

Habitats Regulations Assessment 

A Habitats Regulations Assessment (HRA) establishes whether a project is likely to have a significant effect on protected features of a recognised European protected site. These sites are protected by the Conservation of Habitats and Species Regulations 2017 (the Habitats Regulations).

A HRA is most often required in the context of planning applications, local plans, or other authorisations near or upstream of protected sites.

When do I need a habitats regulations assessment?

There is a legal requirement to conduct a HRA when a development poses a risk of degradation to the species or habitats within a European designated site. 

Special Areas of Conservation (SAC) 

Special Protection Areas (SPA) 

Ramsar sites – Although not designated under the Habitats Regulations, Ramsar sites are afforded the same level of protection in policy. 

What is the purpose of a HRA?

Site Protection

Protect European designated sites by assessing and mitigating potential impacts.  

Compliance

Ensure legal obligations are met.

HRA Process

The habitats regulations assessment (HRA) process follows a clear and structured approach: 

1 | Screening

This determines whether the project will have a significant effect on the site, either alone or in combination with other projects. 

2 | Appropriate Assessment

If significant effects are likely, an Appropriate Assessment is undertaken. This assesses the potential impacts in detail, outlines mitigation measures, and applies an integrity test to determine whether adverse effects on site integrity can be ruled out.

3 | Derogation (if required)

If adverse effects cannot be ruled out, a project may still go ahead under a legal process called derogation. This is only possible if all three of the following tests are met:

No Alternative Routes

There are no 'less damaging' alternatives that exist to achieve the project’s aims. 

Imperative Reason

Imperative reasons of overriding public interest (IROPI) justify proceeding.

Compensatory Compliance

Compensatory measures are in place to maintain the coherence of the UK’s protected site network. 

Possible Outcomes

Following an HRA, there are several potential outcomes:

No significant effects

no further action is required, and the project may proceed.

Mitigation required

Where significant effects are identified, we provide recommendations for avoidance and/or mitigation.

Project Refusal

If no feasible mitigation or alternatives exist and the site’s integrity would be compromised, the project may be refused.
