Grampian conditions or planning obligations: which to use
Securing off-site works turns on one question: is there a reasonable prospect of the event happening within the life of the permission? The answer decides the mechanism.
A Grampian condition prevents development from starting, or from being occupied, until something happens that the applicant does not wholly control, usually works on land in someone else's ownership. A section 106 obligation is a deed, entered into by someone with an interest in the land, that binds the land and can require payment, transfer or the performance of works. When you are securing an off-site junction improvement, a footway link or an access through third party land, the choice between them turns on one question: is there a reasonable prospect of the thing actually happening within the life of the permission?
Get that question wrong and either the council refuses the condition as unenforceable, or the applicant signs an agreement it did not need and pays legal fees it could have avoided.
What a Grampian condition does
A Grampian condition is worded negatively. It does not require the applicant to do anything. It prevents a stated stage of the development from happening until a stated event has occurred.
Two forms are standard. The pre-commencement form stops development starting until off-site works have been approved or completed. The pre-occupation form lets construction proceed and stops occupation until the works are in place, which is usually the better option because it reduces the risk to the developer's programme while still securing the outcome.
The name comes from a case about land the applicant did not own, and that is still the situation where these conditions are most useful. The condition works because it does not purport to compel a third party. It simply says the development cannot proceed past a point until the third party matter is resolved.
The tests a condition must meet
National policy sets six tests, and a condition has to satisfy all of them. It must be necessary, relevant to planning, relevant to the development permitted, enforceable, precise, and reasonable in all other respects.
Enforceability and precision defeat most badly drafted Grampian conditions. A condition requiring "satisfactory arrangements for access" does not say what would satisfy it or who decides. A condition requiring completion of a named scheme, shown on a numbered drawing, before first occupation, is precise and enforceable, because a planning officer can stand on the site and see whether it has been done.
Reasonableness is where the prospects question enters. National guidance is clear that a condition requiring works on land outside the applicant's control should not be imposed where there is no reasonable prospect of the action being performed within the time limit of the permission. That is a lower bar than certainty, and the case law has been generous, but it is a real test.
Where an obligation is the only route
Several things cannot be done by condition at all, and an obligation is the only mechanism.
- A financial contribution. A condition cannot require the payment of money.
- Affordable housing delivery, including tenure, transfer to a provider and occupancy restrictions, which is why an Affordable Housing Statement is nearly always paired with a deed.
- Ongoing management and maintenance obligations extending beyond completion, such as open space management or a travel plan monitoring regime.
- Restrictions that bind successors in title in a way a condition cannot practically police, such as local lettings or occupancy criteria.
- Anything requiring a positive covenant from a third party landowner, because a condition cannot create an obligation on someone who is not the applicant.
Obligations also have to satisfy statutory tests: necessary to make the development acceptable in planning terms, directly related to the development, and fairly and reasonably related in scale and kind. Those tests are statutory rather than policy, which means a contribution that fails them is unlawful rather than merely unwise.
Reasonable prospects and third party land
This is the decision point. Work through it in order.
- Who owns the land the works sit on? If it is adopted highway, the route is normally a highway agreement, and a condition requiring the agreement to be entered into is common.
- Has the third party indicated willingness? A letter of comfort, a heads of terms, or an existing option is powerful evidence of prospects.
- Is there a statutory mechanism that does not depend on goodwill? Highway works under a section 278 agreement, or utility diversions under statutory powers, have a route even where the landowner is not enthusiastic.
- What is the timescale against the life of the permission? Works requiring a traffic regulation order, a stopping up order or a compulsory purchase are slow, and the standard three year implementation period may not accommodate them.
Where prospects are poor, the honest answers are to redesign so the off-site works are not needed, to seek a longer implementation period, or to secure the third party's agreement before the application is determined. A condition imposed on a hope is a refusal deferred. The mechanics of the highway agreements themselves are compared in section 278 works and section 38 adoption compared.
Enforcement differences
The two mechanisms are enforced differently, and the difference matters when things go wrong.
| Aspect | Grampian condition | Section 106 obligation |
|---|---|---|
| Enforced by | Breach of condition notice or enforcement notice | Injunction, or the authority carrying out works and recovering costs |
| Binds | The permission, and so anyone implementing it | The land, and successors in title |
| Money | Cannot require payment | Can require payment, with interest and indexation |
| Changing it | Application under section 73, with a right of appeal | Deed of variation, or an application to modify after five years |
| Public record | On the planning register with the decision | On the register, with the deed usually published |
The section 73 route is the practical advantage of a condition. If circumstances change, the applicant can apply to vary the condition and appeal a refusal. Varying an obligation needs the authority's agreement, or an application to modify or discharge it that is only available once the obligation has been in place for five years.
Cost and timing differences
A condition costs nothing to impose and nothing to discharge beyond the standard fee on a discharge application. An obligation costs both sides in legal fees, and the authority will normally require its own costs to be paid by the applicant.
Timing is the bigger difference. A deed has to be completed before the permission is issued, so a slow drafting process delays the decision itself. Councils routinely hold a resolution to grant for months while an agreement is negotiated, and on a small scheme the delay can exceed the value of what the obligation secures.
That asymmetry is the practical argument for conditions wherever they are available. Where the outcome can be secured negatively, it usually should be.
Choosing between them at drafting stage
Ask four questions and the answer generally follows.
Is money involved? If so, it is an obligation, whatever else is true.
Does the requirement continue after the development is complete? Management, monitoring and occupancy restrictions all point to an obligation.
Can the outcome be expressed as a precise event that must occur before a defined stage of the development? If yes, draft a Grampian condition, name the drawing, name the stage.
Is there a reasonable prospect of the event occurring within the life of the permission? If not, neither instrument saves the scheme and the design needs to change.
Draft the condition yourself and offer it to the officer rather than waiting for their version. Applicants who submit suggested conditions with their application, keyed to drawing numbers, get better conditions than those who receive the authority's standard set. Where the package also involves contributions, set out the heads of terms early so that the deed drafting runs in parallel with determination rather than after it, and keep the Viability Assessment consistent with what is being offered.
This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
What is a Grampian condition?
A negatively worded planning condition that prevents a stated stage of development from happening until a specified event occurs, typically works on land the applicant does not control. It does not compel the third party. It simply stops the development proceeding past that point, which is why it works where a positive requirement could not.
When can a council refuse to impose a Grampian condition?
Where there is no reasonable prospect of the required action being performed within the life of the permission, or where the condition would fail one of the six national tests. Conditions requiring satisfactory arrangements without saying what would satisfy them usually fail on precision and enforceability rather than on prospects.
Why can a condition not require a financial contribution?
Because a condition regulates the use of land, and the power to impose one does not extend to requiring payment. Contributions have to be secured through a planning obligation under section 106, which is a deed binding the land, or through the community infrastructure levy where a charging schedule applies to the development.
Is it easier to change a condition or an obligation?
A condition. An applicant can apply under section 73 to vary it and appeal a refusal. Varying an obligation requires the authority's agreement through a deed of variation, or an application to modify or discharge it, which is generally only available once the obligation has been in place for five years.
Which route is faster?
A condition, by a considerable margin. A deed must be completed before the permission is issued, so councils commonly hold a resolution to grant while the agreement is negotiated, sometimes for months. Where an outcome can be secured negatively by a precise condition, that route usually avoids both the legal cost and the delay.
