Worked example: self-build exemption paperwork for the levy
An illustrative run through the Community Infrastructure Levy self-build exemption forms, in the order the regulations require, with the surcharges that follow a missed step.
The self-build exemption from the Community Infrastructure Levy is lost more often by paperwork than by ineligibility. The claim has to be granted before any work starts, a Commencement Notice has to arrive before the first spade goes in, and supporting evidence has to be filed within six months of completion. Get the self build exemption Community Infrastructure Levy sequence in the wrong order and the full charge becomes payable, with a surcharge on top, and there is no discretion to put it right afterwards.
What follows is an illustrative worked example for a single plot in a charging authority area, with the forms named as the Community Infrastructure Levy Regulations 2010 and the standard national forms use them.
The sequence of levy forms and their order
Five documents do the work. The order is not a matter of preference.
| Stage | Form | When |
|---|---|---|
| Take on the liability to pay | Assumption of Liability (Form 1) | After permission, before starting |
| Claim the exemption | Self Build Exemption Claim Part 1 (Form 7 Part 1) | After permission, before starting |
| Tell the council you are starting | Commencement Notice (Form 6) | After the exemption is granted, before starting |
| Prove you qualify | Self Build Exemption Claim Part 2 (Form 7 Part 2) | Within six months of completion |
| Only where the dwelling is permitted development | Notice of Chargeable Development (Form 5) | Before starting |
The last row catches people converting under Class Q or Class MA. A dwelling created by permitted development is still chargeable development, and the levy process begins with a notice of chargeable development rather than with a planning permission. The self-build exemption is still available.
Assumption of liability before starting work
Assumption of liability is the step that identifies who pays if the exemption falls away. It is not optional for a self-builder, because the exemption is granted to the person who has assumed liability.
Submit it as soon as the permission is issued, in the name of the person who will own and occupy the dwelling. Where a couple are building together, both can assume liability jointly. Where a limited company owns the plot, stop and take advice: the exemption is for an individual building a dwelling to occupy as their sole or main residence, and a company structure will not qualify.
A failure to assume liability before work begins attracts a surcharge of £50 for each owner under the 2010 Regulations. Of the mistakes available here, that one is the least painful.
Claiming the self-build exemption
The claim itself is Part 1 of the self-build exemption form. It goes in after the planning permission has been granted and before any work on site, and the council has to grant it in writing. Nothing happens automatically.
Two points decide eligibility. The dwelling must be built by, or commissioned by, the person who will occupy it, so a contractor build is fine as long as the self-builder commissions it directly. And it must be occupied as that person's sole or main residence for three years from the date of the building control compliance certificate.
The exemption covers the levy only. Any section 106 obligations attached to the permission survive it untouched, as do the costs of discharging conditions before you start, which is where the materials schedule and other pre-start conditions need to be programmed alongside the levy paperwork.
Check the floorspace figures on the claim against the gross internal area on your drawings. Charging authorities calculate the chargeable amount from gross internal area, measured the way the levy regulations define it, and a mismatch between the form and the schedule of accommodation is the most common reason a council comes back with questions and the exemption sits ungranted while you want to start.
The notice that must be served before work starts
The Commencement Notice is the step that undoes the most self-builders. It must be submitted to the collecting authority before development begins, and the exemption is only secured if it is in place.
Two practical rules. Send it after the exemption has been granted, not before, and allow at least a working day between sending it and any activity on site. Second, understand what counts as beginning development: it is the material operations defined in section 56 of the Town and Country Planning Act 1990, which includes digging foundation trenches, laying out a new access and demolition in many cases. Site clearance, a secure hoarding and a site cabin are usually safe. Breaking ground is not.
Failure to submit a Commencement Notice attracts a surcharge of 20 per cent of the chargeable amount or £2,500, whichever is lower, and for self-build it can mean the exemption is treated as never having applied. On a four-bedroom house in a high-rate charging area, that is a five-figure error made by a single omitted email.
Evidence required within the compliance period
Within six months of completion, Part 2 of the self-build exemption form has to be submitted with evidence. Completion for this purpose means the date of the building control compliance certificate, so ask your approved inspector or building control body for it promptly.
The evidence falls into three groups:
- Proof the dwelling exists and is finished, which is the compliance certificate itself.
- Proof of title and of occupation as a sole or main residence, usually a combination of title register, council tax bill, utility accounts and electoral roll entry.
- Proof that the build was a genuine self-build, which the regulations satisfy through an approved claim under the VAT refund scheme for do-it-yourself housebuilders, a specified self-build warranty, or an approved self-build mortgage.
That third group is worth planning for at the start. If you are not reclaiming VAT and not borrowing on a self-build product, you need the warranty in place, and warranties are much harder to arrange retrospectively. Decide which of the three routes you are relying on before you order the foundations.
Consequences of missing a step
The regulations are unforgiving by design, and councils have very little room to help even where they would like to.
Start work before the exemption is granted and the exemption is lost. Start work without a Commencement Notice and the exemption is lost, with a surcharge. Miss the six-month window for Part 2 and the exemption is withdrawn and the full amount becomes payable. Sell or let the dwelling within three years of the compliance certificate and a disqualifying event occurs, which triggers the charge and a further surcharge.
Appeals exist but they are narrow. There is a right of appeal against the imposition of a surcharge and against the calculation of the chargeable amount, not against the loss of an exemption caused by late paperwork. Judicial review is the only remaining route, and it does not reward an applicant who simply forgot.
A worked timeline for a single plot
Illustrative example. A self-builder with planning permission for a single detached house on an infill plot in a charging authority area, working to a nine-month build.
Week 0, permission issued. Week 1, Assumption of Liability and self-build exemption claim Part 1 submitted together, with floor areas cross-checked against the submitted drawings. Weeks 2 to 6, the council acknowledges and grants the exemption in writing; in parallel, pre-start conditions are discharged and the warranty provider is appointed. Week 7, Commencement Notice submitted, with a diary note of the date and a saved copy of the acknowledgement. Week 8, groundworks begin.
Month 9, building control issues the compliance certificate. Within the following six months, Part 2 goes in with the certificate, the title register, a council tax bill in the self-builder's name and the warranty documentation. The three-year clawback period runs from the compliance certificate date, so a sale in month 30 after completion would trigger the full charge.
Keep one folder with every form, every acknowledgement and the dates they were sent. Councils change officers, and the only reliable record of a Commencement Notice served three years ago is the one you kept.
Rates, surcharge figures and form numbering are set nationally by the levy regulations, while the charge per square metre comes from each authority's own charging schedule, so check the current schedule for the area before you budget. A Planning Statement for the application itself should also set out the self-build intention, because it goes to the planning merits as well as to the levy position.

Frequently asked questions
Can I claim the self-build exemption after work has started?
No. The claim must be submitted and granted in writing before development begins, and a Commencement Notice must also be in place. Once material operations as defined in section 56 of the Town and Country Planning Act 1990 have happened, the exemption is no longer available and the full charge becomes payable.
What counts as beginning development for levy purposes?
The material operations in section 56 of the 1990 Act, which include digging foundation trenches, laying out a new access and, in many cases, demolition. Site clearance, erecting a hoarding and bringing in a site cabin are usually outside that definition, but breaking ground is not. If in doubt, serve the notice first.
What evidence does Part 2 of the self-build claim need?
The building control compliance certificate, proof of title and of occupation as a sole or main residence, and one of three self-build proofs: an approved claim under the do-it-yourself housebuilders VAT refund scheme, a specified self-build warranty, or an approved self-build mortgage. It must all arrive within six months of completion.
How long must I live in the house to keep the exemption?
Three years from the date of the building control compliance certificate. Selling or letting the dwelling within that period is a disqualifying event, which makes the full levy amount payable and attracts a further surcharge. Occupation has to be as your sole or main residence, not as a second home.
Does the exemption also remove section 106 obligations?
No. The self-build exemption applies to the Community Infrastructure Levy only. Any planning obligation under section 106 attached to the permission remains enforceable, as do the costs of discharging conditions before you start. Budget for both separately from the levy position.
