Your responsibilities as a public body when carrying out or approving works on or near sites of special scientific interest (SSSIs).
You must take reasonable steps to conserve and enhance the special features of sites of special scientific interest (SSSIs) when:
- carrying out your statutory duties
- giving others permission for works, such as reviewing planning applications
This could be SSSI land that:
- you own or manage
- could be damaged or affected by off-site works - for example if you’re from the Environment Agency and you plan to carry out flood defence work nearby
- could be damaged or affected by planned works by another party that you’ve been asked to approve - including work outside the boundaries of a SSSI
Responsible public bodies include:
- government departments and their agencies
- local authorities, including planning authorities
- ‘statutory undertakers’ such as water and electricity companies
The notification periods in this guidance take precedence over any other statutory review periods for consulting on proposals and issuing consents.
You must consider the potential impact on SSSI land and any special habitats and species of activities and works:
- you plan to carry out as a public body
- proposed by others that you may consent to
To help you assess the impact, you can:
- use the Designated sites system to find out which habitats and species are special features of a site, and which activities are likely to damage them
- use the ‘Magic’ map to view all designations, impact risk zones, waterways and other land features
- read specific guidance on responsibilities for protecting wild birds and their habitats - for example where bird species may be a special feature of an SSSI and could be affected by work on other land where they feed or nest
Natural England consults public bodies in writing about new SSSIs and changes to existing ones, sharing information about the sites. You can use this information to make an assessment of the potential impact of your activities and others’ plans.
When planning your work and approving that of others, you must:
- prefer methods that cause as little damage as is reasonably practicable
- make sure the site can be restored to its former condition, where practicable, if works do cause damage
You could be fined £20,000 in a magistrate’s court or get an unlimited fine in the Crown Court if you:
- do not give Natural England notice of your intention to carry out or approve an activity likely to damage a SSSI
- act before you get Natural England’s response
Public body works
You must ask for advice and approval (known as ‘assent’) from Natural England before carrying out works in line with your statutory duties that are likely to damage the condition or special features of a SSSI. This includes planned works on land outside the boundaries of a SSSI that are likely to damage it. For example, you may need to maintain a road close to a SSSI where the planned works could disrupt a species that’s a special feature. e
You do not need Natural England’s assent for works that you’ve decided are unlikely to damage a SSSI. You could be prosecuted and fined if you damage a SSSI. Contact Natural England if you’re unsure.
- discuss planned works with Natural England
- complete the form to give notice and get assent and email it to email@example.com
Natural England may contact you if it needs:
- more details about your request
- to clarify any issues about your request
You must not carry out works until you get a reply from Natural England.
You can pay for Natural England to do a quick check of your notice to make sure it contains the information required for it to make a decision.
Decisions on assent applications
Natural England will usually reply to you within 28 working days of the date on your notice, to give or refuse their assent. If you do not get a written response within 28 working days, you should take this as a refusal of assent. You can pay for fast-track advice if you need its decision quicker than 28 working days (subject to availability).
Natural England may give you advice on the impact of the proposal and give their assent with conditions. For example, it might say that the work should be carried out at a certain time of year to limit damage to the land. You may also need to apply for a licence if the work will have an impact on a protected species.
If you decide to go ahead without assent
You can still carry out works if:
- Natural England refuses to give its assent
- you believe the conditions attached to an assent are unacceptable
You must give Natural England written notice at least 28 working days before the start of the works if you intend to go ahead without assent. You must show that you’ve:
- taken into account any advice Natural England gave you
- considered alternatives that could reduce the impact on the SSSI, such as using lighter vehicles to carry materials
- weighed the balance between conflicting interests, including the special interest of the SSSI
Natural England may refer a case to the Secretary of State for Environment, Food and Rural Affairs if it still has serious concerns about the potential damage to a SSSI. This can lead to a judicial review of the public body’s decision to go ahead with the works.
You could be prosecuted and made to restore the features of a SSSI if you:
- fail to notify Natural England of the works
- do not take account of Natural England’s advice
- cause more damage than necessary
In an emergency, utility companies and other bodies may need to enter SSSI land or carry out essential works nearby. It may not be possible to ask for Natural England’s assent or give Natural England the 28 working days’ notice that’s normally required before beginning work. In this situation, you should:
- tell Natural England about the work you’re carrying out as soon as possible and preferably within 24 hours of entering a SSSI or nearby land by contacting firstname.lastname@example.org
- make sure the emergency work causes as little damage to the special features as possible
You cannot regard works that have included planning in advance as emergency works.
You must check if you need Natural England’s permission if you own or occupy SSSI land as a public body and plan to carry out only non-statutory works, such as agricultural or recreational activities.
Read the guidance for owners and occupiers of SSSI land to find out when you need Natural England’s consent and how to ask for it in this situation.
Approving works by others
Other public bodies, such as planning authorities, national park authorities, the Forestry Commission and Historic England, are also responsible for permitting others to carry out works that are likely to damage or affect SSSIs. However, they must ask for Natural England’s advice before giving any permission.
Find out more about how to review planning applications.
You’re responsible for making decisions on proposals and asking for Natural England’s advice where a plan or project is likely to damage an SSSI unless:
- another competent authority has already assessed a proposal, in which case you can choose to accept their decision
- you believe it would be more appropriate for another competent authority to assess the proposal
Ask for Natural England’s advice
If you want to give permission for planned works you should first discuss this with Natural England.
Advice and conditions
Natural England will usually reply to you within 28 working days of receiving your written notice to advise you whether to give permission or not. You can assume Natural England has no comments to make if you do not hear back within 28 working days.
Natural England may give you advice on the likely impact of the proposal and recommend that you give your permission only with conditions. For example, Natural England might say that it would be best to carry out the work using particular materials. You or the developer may also need to apply for a licence if the work will have an impact on a protected species.
If Natural England advises consent refusal
You can still approve works if:
- Natural England recommends you do not give permission
- you believe the conditions Natural England suggested you attach to a permission are unacceptable
However, if you intend to do so you must again give Natural England notice.
Write to or email Natural England at least 21 working days before the start of the works, including a copy of the permission you propose to give.
As with works carried out by public bodies, you must explain how:
- you’ve taken Natural England’s advice into account
- considered alternatives
- assessed differing interests in order to reach your decision
Natural England may refer a case to the Secretary of State for Environment, Food and Rural Affairs if it still has serious concerns about the potential damage to an SSSI. The Secretary of State may decide to stop you giving permission until your decision to approve the work has been reviewed at a public inquiry, or Natural England may ask for a judicial review of the decision.
When assent or consent is frequently needed
Natural England may work with public bodies to:
- give their assent or consent in advance for general and recurring operations that the body will carry out or consent to
- agree ‘memoranda of understanding’ with public bodies who have large landholdings and frequently require consents, in order to speed the process in future and better protect a site’s special features
Sites of international significance
If you want to carry out or approve work on or near an SSSI that’s also a protected European or Ramsar site, such as a Special Area of Conservation or Special Protection Area, you’ll need to carry out a habitats regulations assessment (HRA).
You must include a copy of the HRA with your notice for assent or to give consent if it shows there’s a likely significant effect of the activity on the protected site.
You should still contact Natural England for advice.
Get advice from Natural England
Get free or charged advice before submitting your proposal to carry out or approve works on or near SSSIs. This will reduce delays to the assent or consent process.
You can get free advice from Natural England:
- to check whether your proposal will significantly affect a protected site or species
- on what you should include with your proposal
- about routine and repeated activities on the protected site, including routine agricultural activities
- about activities mainly aimed at achieving favourable condition (that is habitats and features which are in a healthy state and being conserved by appropriate management)
In all cases you’ll get an initial free consultation from Natural England.
Pay for advice
You can pay for extra advice from Natural England if what you want to do is more complicated. Natural England can:
- help you review your survey results
- advise on your mitigation strategies to reduce damage to the environment
- help if you need advice quickly (in fewer than 28 working days)
- help if you need complex advice to meet a defined deadline
Contact Natural England as soon as possible if you need its advice quickly. It’ll be most useful before you submit your consent application.
How much you might pay depends on:
- the amount of advice you require from Natural England and how complex your proposal is
- whether or not a Natural England adviser needs to visit your site
- how quickly you need our advice
If you want advice to avoid damage to protected sites or species, you’ll pay £110 per hour.
