Appealing a Community Infrastructure Levy surcharge

A surcharge imposed under the Community Infrastructure Levy Regulations 2010 is appealed to the Planning Inspectorate, not to the council that issued it, and you have 28 days from the day the surcharge was imposed to get the appeal in. Miss that window and the surcharge stands even where your complaint about it is sound. A CIL surcharge appeal is a narrow documentary process about two things: whether the breach the authority relies on actually happened, and whether the authority served the notices the regulations require it to serve. Almost everything that decides it is paperwork you either have or you do not.

Who decides a levy surcharge appeal

The 2010 Regulations split levy appeals between two bodies, and sending the wrong form to the wrong place is the most common way to lose the deadline. The Valuation Office Agency handles the money questions. The Planning Inspectorate, acting through an appointed person, handles the conduct questions.

A regulation 113 appeal against the chargeable amount also has a step before it. You must first ask the collecting authority for a review under regulation 113, and only then can the matter go to the Valuation Office Agency. Surcharge appeals under regulation 117 have no equivalent internal review stage, which is why the 28 days are so tight.

The 28 day clock and how it is counted

The period for a regulation 117 appeal runs from the date on which the surcharge was imposed, not the date you opened the envelope and not the date you first knew the demand notice was wrong. For a regulation 118 deemed commencement date appeal, the 28 days run from the day the demand notice was issued. Both are counted in calendar days, weekends and bank holidays included.

Councils rarely extend anything here because they have no power to. And the appointed person cannot cure a late appeal by treating it as something else. If a surcharge letter lands while the person who handles the site is on leave, the sensible response is to lodge a protective appeal on the ground you can state today and file the supporting evidence afterwards.

Grounds that succeed and grounds that do not

Regulation 117 gives three grounds, and an appeal has to fit one of them. The first is that the claimed breach did not occur. The second is that the collecting authority did not serve a liability notice for the chargeable development the surcharge relates to. The third is that the authority did not follow the procedure the regulations set for imposing the surcharge.

What does not work is any argument that the surcharge is harsh, that the amount is out of proportion to the development, or that the applicant did not understand the regime. Appointed persons have no discretion to reduce a surcharge that was properly imposed. Nor can they revisit the charging schedule rate, which was tested at the charging schedule examination and is fixed for everyone in the charging area.

The three surcharges that generate most appeals sit in regulations 80 to 85. Failure to assume liability attracts a fixed sum for each owner. Failure to submit a commencement notice before development starts attracts 20 per cent of the chargeable amount or £2,500, whichever is the lower. Late payment attracts a percentage of the outstanding amount, applied in stages as the debt ages, with a floor figure. Read the current consolidated text before you quote a figure, because the amounts and the automatic consequences have both been amended since 2010.

Paying while the appeal is undetermined

Lodging an appeal does not suspend the demand notice. The levy remains payable on the dates the notice sets, late payment surcharges keep accruing on anything properly due, and a collecting authority can move to recovery while the appointed person is still reading your grounds.

The practical course is to pay the part of the demand that is not in dispute and appeal only the surcharge. That protects you from a second surcharge stacking on top of the first while the appeal runs. If the appeal is allowed, the collecting authority recalculates and refunds. If it is dismissed, you have not added a late-payment penalty to a bill you were always going to owe.

Proving what was served and when

Most regulation 117 appeals turn on service. The collecting authority has to serve a liability notice as soon as practicable after planning permission first permits development, and a demand notice after commencement. If no liability notice was served, ground two is made out and the surcharge falls away regardless of what else happened.

Your side of the record matters just as much. A commencement notice must reach the collecting authority before the day development starts, and the burden of showing it arrived sits with you. Keep proof of posting or recorded delivery, keep the email with its timestamp and any read receipt, and keep a dated note of the call if you telephoned the CIL officer. A scanned copy of a form with no evidence of transmission is not proof of service, and appointed persons have said so. Photographs of the site on the date works began, invoices from the groundworks contractor and the building control initial notice all help to fix the real commencement date.

It is worth distinguishing this exercise from a planning appeal against a refusal, where the argument is about planning merits rather than documents. If you are weighing both at once, reading the reasons for refusal carefully before deciding to appeal is a separate piece of work with its own timetable.

Challenging a deemed commencement date

Where a collecting authority thinks development started without a commencement notice, it determines a deemed commencement date itself and calculates the levy and any surcharge from that date. Regulation 118 lets you appeal on the ground that the authority got that date wrong.

This is the appeal where site evidence earns its keep. What counts as commencement is the carrying out of a material operation as defined in section 56(4) of the Town and Country Planning Act 1990, which includes digging foundation trenches, laying out a road and demolition in some circumstances. Site clearance, fencing, topsoil stripping and investigative trial pits are often argued not to be material operations, and the answer depends on the facts rather than on a rule of thumb.

An illustrative example. A collecting authority takes the date of an aerial photograph showing a levelled site as the deemed commencement date. The developer produces a contaminated land investigation report dated three weeks later, a contractor appointment dated after that, and the building control initial notice later still. The levelling was ground investigation, not a material operation. On that evidence the deemed date is arguably wrong by a month, which changes both the payment date and whether a late-payment surcharge could be imposed at all.

Decisions of appointed persons are published, and they are useful for seeing how this line has been drawn. They are indicative rather than binding, in the same way that appeal decisions used as evidence in an application carry weight without settling anything.

Where the regulations give no right of appeal

Three situations catch people out. Losing the right to pay by instalments after a missed commencement notice is a consequence of the instalment policy, not a surcharge, so there is nothing to appeal. A disqualifying event that removes self-build or annexe relief within the clawback period ends the exemption by operation of the regulations. And a refusal of discretionary relief, such as exceptional circumstances relief, is a decision of the charging authority rather than an appealable determination.

In those cases the only routes left are a request that the authority exercise discretion in how it recovers, or judicial review of the decision-making process, which is expensive and rarely proportionate for a domestic-scale liability.

The wider levy picture is also moving. The Levelling-up and Regeneration Act 2023 contains powers for an Infrastructure Levy to replace CIL in England, but as at September 2026 those powers have not been brought into force and the 2010 Regulations continue to apply. Do not plan an appeal around a regime that is not yet in force.

Getting the paperwork right at application stage prevents most of this. A clear Planning Statement that sets out the floorspace being created and the floorspace being demolished gives the collecting authority the figures it needs, which is where a surprise chargeable amount usually starts.
