Levy surcharges and the cost of a missed notice
Missing a levy notice costs a fixed surcharge, interest, and often the right to pay by instalments. Here is each surcharge, the appeal route and the checklist that prevents it.
The Community Infrastructure Levy punishes paperwork failures with money, and the amounts are set in the regulations rather than left to the council. Failing to assume liability attracts a fixed surcharge. Starting work without serving a commencement notice attracts a surcharge of 20 per cent of the chargeable amount, capped, and can cost you the right to pay by instalments at the same time. On a modest self-build that combination turns an administrative slip into a five-figure demand due immediately.
None of it is discretionary. A collecting authority applying a surcharge is applying a regulation, and sympathy is not a ground of appeal.
The notices the regulations require and when
Four documents drive the sequence, and three of them are yours to serve.
The collecting authority issues a liability notice once permission is granted, setting out the chargeable amount and who it believes is liable. You then assume liability using the national form, before development starts. You serve a commencement notice before development starts, stating the intended date. The authority then issues a demand notice setting out what is payable and when.
Two points about timing catch people out. The liability notice can arrive weeks after the decision notice, and the obligation to assume liability and serve a commencement notice does not wait for it. And the regulations attach the consequences to the start of development, not to the start of construction, so a material operation on site begins the clock whether or not anyone intended it to.
Where the project is an extension that may fall under the levy threshold at all, settle that question before worrying about notices, because the analysis in when an extension crosses the levy threshold determines whether you are in the regime.
Surcharges for failing to assume liability
If nobody has assumed liability when development starts, the regulations allow the collecting authority to impose a surcharge of £50 for each person liable to pay.
In isolation it is a small sum. Its real cost is what it signals. Where liability has not been assumed, the authority recovers the levy from the landowners of the material interests in the land, which brings in parties who may not have expected to be involved, and it can apportion liability between them with a further surcharge of £500 in respect of each material interest where apportionment is required.
On a plot bought with a permission already granted, this is the scenario to avoid. Assume liability in your own name as soon as you have the permission reference, even if the start date is a year away, because assumption can be withdrawn or transferred later and the surcharge cannot be undone.
Surcharges for starting without a notice
This is the expensive one. Where development starts and the collecting authority has not received a commencement notice, the regulations allow a surcharge of 20 per cent of the chargeable amount or £2,500, whichever is the lower.
Three features make it worse than it looks.
The cap is low enough that the surcharge is often the smaller part of the damage. The authority may also determine a deemed start date, which fixes when payment becomes due and can mean the levy is already overdue when the demand notice arrives. And the instalment policy may fall away, which is dealt with below.
A disqualifying event in relation to an exemption or relief carries its own surcharge, again at 20 per cent of the chargeable amount or £2,500, whichever is the lower. Failing to respond to an information notice from the authority carries a further surcharge on a similar basis with a lower cap.
| Breach | Surcharge in the regulations |
|---|---|
| Failure to assume liability | £50 for each person liable |
| Apportionment of liability required | £500 for each material interest |
| Start without a commencement notice | 20 per cent of the chargeable amount or £2,500, the lower |
| Disqualifying event for an exemption or relief | 20 per cent of the chargeable amount or £2,500, the lower |
| Failure to comply with an information notice | A percentage of the chargeable amount subject to a lower cap |
The regulations have been amended a number of times since 2010, so take the current figures from the consolidated text rather than from a council leaflet of uncertain vintage.
Interest and late payment surcharges
Late payment attracts both a surcharge and interest, and they run separately.
The late payment surcharge is a percentage of the overdue amount, applied in stages: a first surcharge once the payment is 30 days overdue, subject to a minimum sum, and further surcharges at six months and at twelve months. Each one is calculated on the amount still outstanding at that point, so partial payment reduces the later surcharges.
Interest runs at a rate tied to the Bank of England base rate, set in the regulations at a margin above it, calculated on a daily basis on the outstanding amount. On a levy bill of any size, interest over a year is a real number, and it is not negotiable.
Unlike planning application fees, which are revised and indexed on a published national schedule each April, levy rates and the sums in a liability notice are indexed by the mechanism in the regulations against the charging schedule in force. The two systems are often confused, and how planning fees are indexed each April is a separate process with separate dates.
Losing the right to pay by instalments
Most charging authorities adopt an instalment policy, and for a self-builder or a small developer it is often the difference between a manageable cost and a funding problem. A typical policy allows payment in two or three tranches over a period after the start of development.
The policy applies only where the procedural requirements have been met. Where development starts without a commencement notice having been received, the instalment policy does not apply and the whole chargeable amount becomes payable, usually within a short period of the deemed start date. Missing an instalment can have the same effect, with the outstanding balance becoming payable in full.
That is the mechanism that converts a forgotten form into a cash crisis. The surcharge is capped. The acceleration is not.
Check the authority's published instalment policy before you set the build programme, note the trigger dates, and diarise each payment against the start date you stated in the commencement notice rather than against the date work actually began.
Review and appeal against a surcharge
There are routes, and they are short.
A surcharge can be appealed to an appointed person, in practice at the Valuation Office Agency, within a short window from the date the surcharge is imposed. The grounds are narrow: that the claimed breach did not occur, that the collecting authority failed to serve a liability notice in respect of the development, or that the surcharge has been calculated incorrectly.
Separate routes deal with separate decisions. The chargeable amount itself is challenged first by requesting a review from the collecting authority within the period set in the regulations after the liability notice, then by appeal to the Valuation Office Agency. A deemed start date can be appealed on the ground that the authority got the date wrong. Relief and exemption decisions have their own routes.
Two practical points. The time limits run from the notice, not from when you opened the post, so date-stamp everything the authority sends. And an appeal does not suspend the liability, so engage with the authority about payment at the same time as appealing.
Where the authority will not move and the sums are large, the enforcement powers are worth knowing about rather than discovering: a levy stop notice preventing further development, recovery through the courts, and a charge on the land that shows up on any sale.
A checklist that prevents the problem
Pin this to the site file at the point permission is granted.
- Record the permission reference and the date, and diarise a check for the liability notice four weeks later.
- Submit the assumption of liability form in the correct name, and keep the acknowledgement.
- Claim any exemption or relief and wait for the written decision before anything happens on site.
- Read the authority's instalment policy and note the trigger dates.
- Serve the commencement notice, by a method that proves delivery, before any material operation, and keep the receipt.
- Tell your groundworker, in writing, not to start before a stated date, and confirm it on the day.
- Diarise each payment date and each exemption deadline, including the three-year clawback end date where a self-build exemption applies.
The sixth item prevents more surcharges than the other six combined. A contractor who turns up a week early to make use of dry weather has started the development, and the regulations do not care that the notice was in the post.
Budget the levy alongside the other costs that land on a small site, including the water and drainage connection charges, and keep the levy file separate from the planning file.

Frequently asked questions
What is the surcharge for not assuming liability?
The regulations allow the collecting authority to impose a surcharge of £50 for each person liable to pay. The larger consequence is that the authority recovers from the landowners of the material interests instead, and can apportion liability between them with a further surcharge of £500 for each material interest where apportionment is needed.
What happens if I start work without serving a commencement notice?
The authority can impose a surcharge of 20 per cent of the chargeable amount or £2,500, whichever is lower, determine a deemed start date that fixes when payment falls due, and disapply its instalment policy so the whole amount becomes payable. The acceleration usually costs more than the capped surcharge.
Does late payment attract interest as well as a surcharge?
Yes, and they run separately. Late payment surcharges apply in stages once payment is overdue, calculated on the amount still outstanding at each stage. Interest runs daily at a rate set in the regulations as a margin above the Bank of England base rate. Partial payment reduces the later surcharges.
Can I appeal a levy surcharge?
Yes, to an appointed person at the Valuation Office Agency, within a short window from the date the surcharge is imposed. The grounds are narrow: that the breach did not occur, that the authority failed to serve a liability notice for the development, or that the surcharge was calculated incorrectly. An appeal does not suspend liability.
How do I keep the right to pay by instalments?
Meet the procedural requirements and pay each instalment on time. Where development starts without the authority having received a commencement notice, the instalment policy does not apply and the full chargeable amount becomes payable. Missing one instalment can make the outstanding balance payable in full.
What is the most common cause of a levy surcharge?
A contractor starting early. A groundworker who arrives a week ahead of programme to use dry weather has started the development, and the regulations take no account of a notice that was in the post. Tell the contractor in writing not to start before a stated date and confirm it on the day.
