CIL process and forms to submit

Additional CIL forms which have not been submitted with your original planning application should be emailed to

We have created a CIL Process Flowchart to help you go through the CIL process and submit the right forms at the right time. 

It is important that you follow this process, as otherwise surcharges may apply. All exemptions must be applied for prior to commencement. Continuous lawful use evidence must be submitted within 28 days of your liability notice.

The step by step guide to the process tells you which form to submit when. The forms you may need are:


Step 1: Planning application

The CIL process begins when a planning application is submitted, you need to submit 'Form 1: additional information' with your planning application.

The additional information form asks for details of new floorspace to be created by the development, and details of any floorspace to be demolished, which can be offset against the new floorspace calculation. It is in your interest to provide this information, especially where there are existing buildings in use on your site, in order to ensure that the CIL calculations can be completed correctly.

If the application is CIL liable, 'Form 2: assumption of liability' will be required at the same time. 

In some cases, proposals liable for CIL can be commenced with Permitted Development. When this is the case it will be your responsibility to inform the us using 'Form 5: Notice of Chargeable Development' before commencement begins.

Step 2: Liability

It is important that you inform us about who will be responsible for paying the CIL if permission is granted. 'Form 2 assumption of liability' needs to be submitted before validation of your planning application. 

If at any time during the process, you wish to withdraw or transfer liability of the charge for example, if you sell the site then you need to complete and submit either 'Form 3 withdrawal of assumption of liability' or 'Form 4 transfer of assumed liability'.

Once planning permission has been granted, we will issue a Liability Notice to all relevant parties (as well as the landowner, if the two are different). If any changes occur after the Liability Notice is issued, we will issue a revised notice that will supersede the previous one.

Step 3: Exemptions

The Regulations provide for exemption from CIL in the following circumstances:

  • Social housing developments
  • Charitable developments provided by a charity for charitable purposes
  • Self-build developments
  • Self-build residential extensions
  • Self-build residential annexes

Whilst the Regulations also permit local authorities to provide discretionary charitable relief, exceptional circumstances relief and discretionary social housing relief, Cotswold District Council is currently not proposing to make such relief available. We are committed to keeping this decision under review.

You will need to submit the relevant form (CIL forms 7 to 10) for the type of exemption you need. 

Warning Relief is not automatically available; it must be applied for before the start of development.

The completed form must be submitted to the Council before commencement of development in order to obtain relief. We can not process request for relief retrospectively after commencement. Note that the regulations allow for an exception on this rule when submitting a section 73 application for a permission for which you already received relief. Please use 12 or 13 to request the relief to also be applied to your section 73 application.

Please note to check compliance with the conditions of your relief, we may share personal information with our Revenues team.

If any relief is granted, where relevant, we will be issue a revised Liability Notice to reflect any changes as a result of the relief. This will supersede any previous notice we have sent.

Step 4: Commencement and payment

The regulations require the submission of 'Form 6 Commencement Notice' by the liable party before the starting development.

It is vital that a Commencement Notice is submitted before development starts. The CIL Regulations provide that where a Commencement Notice has not been received before commencement, those liable will no longer be able to benefit from the Instalment Policy.

In addition we may issue a surcharge of 20% of the chargeable amount or £2,500, whichever is the lower amount. For developments benefiting from relief where a commencement notice is required, a surcharge of 20% of the notional chargeable amount (so the amount before the relief is applied) or £2,500 whichever is the lower amount.

Once we have received a Commencement Notice, we will issue a Demand Notice. This notice will detail who is liable, for how much, any reliefs or surcharges payable, and will also specify the dates on which the payments are due. In line with the regulations Part 8 Section 70 and our Instalment policy, whichever is relevant.

Warning If you have not submitted a valid Commencement Notice before development starts we will determine a commencement date and payment will be due in full on that date.

If you are applying for (part) retrospective planning permission, the development will be deemed to have commenced on the day permission is granted. You will not be able to submit a Commencement Notice as the development has already commenced and surcharges will be applied accordingly.

For developments where extension relief has been granted or where the liable amount is £0 before any relief is applied, no commencement notice is required.

Step 5: Completion

If you have applied for a self-build exemption, within six months of completion of self-build housing the liable person must submit 'Form 7 self build exemption notice part 2'.

You will also need to provide the following: 

  • proof of completion (building control compliance or completion certificate)
  • proof of ownership (title and deeds)
  • proof of occupation of the dwelling (Council tax certificate), and two further proofs of evidence (utility bill, electoral roll, bank statement).   

You must also include one of the following:

  • an approved claim for a VAT refund for DIY housebuilders
  • a self-build warranty
  • an approved self-build mortgage

Failure to submit the appropriate form and evidence within six months of completion of the development will result in the withdrawal of the exemption and payment in full of the liable amount.

Step 6: Disqualifying events

If something occurs that disqualifies you from your exemption, you need to notify the Council within 14 days of the day the disqualifying event occurred, otherwise surcharges will apply.

Disqualifying events are things like letting out a residential annex that had received annex relief within the clawback period of 3 years, selling your property which had received self-build relief within 3 years of completion.

Please see CIL regulations 42C, 48, 53, 54D, and 57 for all disqualifying events or if you're unsure, email
