Assumption of liability for the levy
Assuming liability on the levy's Form 2 fixes who the council will pursue for the Community Infrastructure Levy. It has to be done before work starts, and before any relief claim, or liability falls back on the landowners.
If your site is in an area with a Community Infrastructure Levy charging schedule, somebody has to tell the council they will pay it. That step is the assumption of liability, made on the levy's Form 2, and it has to be submitted to the collecting authority before development starts. Miss it and liability falls back on whoever owns the land, a surcharge applies, and any relief you were counting on becomes harder to secure. For a self-builder the sequencing matters more than the form itself, because the self-build exemption only works if assumption of liability comes first.
What assuming liability means
Assuming liability is a formal statement that you accept responsibility for paying the levy on a chargeable development. It is made under regulation 31 of the Community Infrastructure Levy Regulations 2010, using the assumption of liability notice that most people know as Form 2.
The levy itself was created by Part 11 of the Planning Act 2008 and only bites where the charging authority has adopted a charging schedule. So the first question is not who assumes liability but whether there is a charge at all. Check the authority's published charging schedule and its rates by use and zone before you worry about the paperwork.
Assumption does not calculate the sum. The council does that in the liability notice it issues after permission is granted. Assumption simply fixes who the council will pursue.
Who can assume it and when
Any person may assume liability, and more than one person can assume it jointly. In practice it is the applicant, the landowner, the main contractor or a special purpose company, and the choice has real consequences because the council will chase the assuming party rather than the land.
The timing rule is the one that catches people. Liability must be assumed before the day development starts. Not before the first payment falls due, and not in the same envelope as the notice telling the council that work is beginning.
For anyone claiming relief, the order is fixed:
- Permission is granted and the council issues a liability notice setting out the chargeable amount.
- You submit the assumption of liability notice (Form 2).
- You claim the exemption or relief you are entitled to, and wait for the council to confirm it in writing.
- You submit the commencement notice (Form 6) before any material operation on site.
- Work starts.
Get the exemption claim in before step 4 and before anything happens on site. A digger that arrives before the paperwork is a problem that cannot be fixed retrospectively. The self-build exemption from the levy is the clearest example, because it runs through all five steps and then adds a further evidence stage after completion.
Consequences of nobody assuming liability
Where no one has assumed liability by the time development starts, the regulations make the owners of the relevant land liable by default, apportioned between material interests. That is rarely what anyone intended, and it is a particular problem on a plot bought from a landowner who retains an interest or where the land is in joint names.
Two further consequences follow. A surcharge applies for failing to assume liability, set at £50 per person in the regulations as originally made. And relief that depended on the claimant having assumed liability becomes unavailable, because the claim is made by the person who assumed it.
| What is missed | Consequence in the regulations |
|---|---|
| Assumption of liability before the start | Default liability on the landowners, plus a £50 surcharge per person |
| Commencement notice before a material operation | A surcharge based on a percentage of the chargeable amount, subject to a cap |
| Payment by the due date | Late payment surcharges stepped at 30 days, six months and twelve months, plus interest above the Bank of England base rate |
Those figures sit in the regulations as amended, and the levy regulations have been amended repeatedly since 2010, so check the current consolidated version rather than a figure quoted on a forum.
Transferring and withdrawing liability
Assumed liability can be transferred to another person, which is the mechanism used when a plot is sold part-built or when a developer takes over from a landowner. The transfer is made on the levy's transfer form and has to be notified to the collecting authority. It is normally available up to the point where the final payment falls due, but the detail sits in the regulations, so read them before you rely on it.
Withdrawal is narrower. A person who has assumed liability may withdraw it, but only before development starts, and withdrawal pushes liability back to the default position unless someone else assumes it. On a site where the build is already under way, withdrawal is not the answer. A transfer is.
One honest uncertainty worth flagging: collecting authorities differ in how quickly they acknowledge these notices, and an unacknowledged form is not evidence of anything. Chase a written acknowledgement and keep it.
Relationship with the commencement notice
The assumption of liability notice and the commencement notice do different jobs, and submitting one does not satisfy the other. Assumption says who pays. The commencement notice says when the clock starts, because the payment schedule and any instalment policy run from the date stated in it.
Before 2019, failing to serve a commencement notice could cancel a self-build exemption outright, which produced some harsh outcomes on small sites. The 2019 amendments changed the consequence to a surcharge. The position has moved more than once, so read the current regulations rather than older commentary, and serve the notice anyway.
What counts as starting work is the same material operations test that runs through planning conditions, so it is worth understanding what amounts to development and when works begin before you book the groundworks.
Records to keep
Keep a single file for the levy from the day permission is granted. It should hold the liability notice, your Form 2 and the council's acknowledgement, the relief claim and the written decision on it, the commencement notice with the date you served it and proof of service, the demand notice, and receipts for every payment.
Add the completion evidence for any relief that requires it. For a self-build claim that means the documents the regulations list within the period they specify after the dwelling is finished, which commonly includes a completion certificate, proof of occupation as a sole or main residence, and the warranty or approved inspector documentation.
If the site changes hands, hand the file over with the title pack. The next owner inherits the consequences of a missed notice.
Common sequencing errors
The recurring mistakes are small and expensive. Starting groundworks before serving the commencement notice. Claiming an exemption without having assumed liability first. Assuming liability in the name of a company that is then dissolved. Treating an extension or annexe as automatically outside the levy when the exemption has to be claimed. Letting a contractor order a site strip while the relief decision is still pending.
And one more: assuming the levy does not apply because nobody mentioned it. The liability notice arrives after permission, sometimes weeks after, and it is addressed to the applicant rather than to the person doing the building.
A liability notice with the wrong floor area or the wrong relief applied can be queried, and the council can issue a revised notice. Raise it in writing as soon as you spot it rather than waiting for the demand.
If you are putting an application pack together for a new dwelling, you can see which reports the site is likely to need and draft the supporting statements before your own review.

Frequently asked questions
When must Form 2 be submitted?
Liability must be assumed before the day development starts. There is no fixed lead time in the regulations, but leaving it to the same week as the groundworks is risky because any relief claim has to come after the assumption and be decided before work begins. Submit it as soon as the liability notice arrives.
What happens if nobody assumes liability?
Liability defaults to the owners of the relevant land, apportioned between their material interests, and a surcharge applies for the failure to assume. Relief that depends on the claimant having assumed liability also becomes unavailable. On jointly owned land or a plot where the seller retains an interest, that outcome is rarely what anyone intended.
Can assumed liability be transferred to a buyer?
Yes. A person who has assumed liability can transfer it to another person using the levy transfer form, notified to the collecting authority. This is the usual route when a part-built plot is sold or a developer takes over from a landowner. Withdrawal is different and is only available before development starts.
Does assuming liability tell me how much I owe?
No. The collecting authority calculates the chargeable amount in the liability notice it issues after permission is granted, using its adopted charging schedule, the indexation in the regulations and any deductions for existing floorspace. Assumption only records who the authority will pursue for payment.
Is a residential extension always outside the levy?
No. Extensions and annexes can qualify for relief, but the relief has to be claimed and granted before work starts rather than applying automatically. Check your charging authority's schedule, submit the assumption of liability notice, then claim. Treating the works as outside the levy without a written decision is one of the more common and costly errors.
