Grampian conditions where land is outside your control

A Grampian condition planning solution is a negatively worded condition that stops development going ahead until something has been done on land the applicant does not control. No development until the access has been built. No occupation until the off-site sewer has been laid. It exists because a planning obligation needs the landowner's signature and a condition does not, so where the third party will not sign, the condition is the only mechanism left.

The name comes from a Scottish case about an access road, and the device has been standard practice in England ever since. The limit on it is not legal validity but deliverability: a permission subject to a condition you cannot satisfy is a permission you cannot implement.

What a Grampian condition does

It converts an off-site requirement into a precondition of the permission. The authority grants consent, and the consent cannot be acted on until the stated works exist.

The mechanics are important. The condition does not oblige you to carry out the works, and it does not oblige the third party to let you. It simply withholds the ability to develop until the works are in place. If they never happen, the permission sits unused and lapses.

That asymmetry is why these conditions are acceptable to authorities. The authority is not purporting to control land outside the application site, which it has no power to do. It is attaching a condition to what it is granting.

Courts have held that such a condition is not unlawful merely because there appear to be no prospects of it being fulfilled. The guidance on the use of planning conditions takes a more practical line: a condition requiring works on land not controlled by the applicant should only be used where there are at least reasonable prospects of the action being performed within the lifetime of the permission.

The reasonable prospects test

In practice that test is applied at the point of decision, and it has two consequences.

First, the absence of reasonable prospects is a material consideration in deciding whether to grant at all. An authority faced with a scheme that depends on a ransom strip whose owner has refused in writing may refuse permission rather than grant a permission that cannot be implemented, and an inspector may take the same view on appeal.

Second, you can improve the prospects and should say so. Evidence of a heads of terms with the third party, a signed option, a draft agreement, a payment in escrow, or correspondence showing a willingness to deal all move the assessment. So does evidence that the works could be delivered by a statutory route if negotiation fails, such as a utility undertaker's own powers to lay apparatus.

Silence is read as a problem. If the application says nothing about how the off-site works will be secured, the officer assumes they have not been thought about.

Where a condition is preferred to an obligation

The choice between a condition and a planning obligation is mostly about who has to sign.

So a condition wins where the third party is unwilling, uncontactable or simply numerous. An obligation wins where money has to change hands, where ongoing management is needed, or where the authority wants a covenant running with the land. The split between those mechanisms and highway agreements is set out in section 278, section 38 and section 106: which secures what.

One drafting trap. A condition requiring the applicant to enter into an agreement is not a safe condition, because performance depends on another party's consent. The guidance treats conditions requiring an applicant to enter into a planning obligation as unlikely to be enforceable. Specify the physical outcome instead.

Highway and drainage works as typical subjects

Four categories account for most Grampian conditions.

Highway works on the public highway: a new access, a widened bellmouth, a footway link, a bus stop upgrade, a right-turn lane. The highway is land in the highway authority's control, and the works are usually delivered under a highway agreement, so the condition requires the works and the agreement delivers them.

Visibility splays across adjoining private land, where a hedge or verge outside your ownership has to be cut back and kept clear in perpetuity.

Off-site drainage: a connection to a sewer in a neighbouring field, an outfall into a watercourse with a third party's bank, or a capacity upgrade the undertaker has to carry out.

Utility diversions and connections, where the apparatus is the undertaker's and the route crosses third party land.

In each case the condition should describe the works, not the process. "No dwelling shall be occupied until the footway shown on drawing 1234 Revision B has been constructed and made available for public use" is discharged by inspecting a footway. "No dwelling shall be occupied until a section 278 agreement has been completed" is discharged by a document the authority itself has to sign, which no one would call a workable condition.

Drafting that can be discharged

Six features of a condition you can actually satisfy:

1. A clear trigger. "No development shall take place until" is the strictest, "prior to first occupation" is softer, and "prior to occupation of the twentieth dwelling" lets you build and sell while the off-site works proceed. Negotiate for the latest defensible trigger.
2. A defined physical outcome, tied to a drawing with a revision number.
3. A stated standard, by reference to the highway authority's specification or a named technical document.
4. A named approving body, and whether approval is in writing.
5. No requirement for a third party's agreement as the thing to be achieved.
6. An exception for works outside your control once you have done everything reasonable, where the authority will accept one.

That last point is worth asking for. A condition requiring visibility to be provided and thereafter maintained over land you do not own is impossible to comply with in perpetuity. A condition requiring it to be provided before occupation, and maintained so far as the land within the applicant's control allows, is compliable.

Risk when the third party will not cooperate

The permission becomes an asset you cannot use. There is no appeal against a refusal to discharge a condition on grounds that the third party is being difficult, and no mechanism to compel a private landowner to sell a strip of land for an access.

Your realistic options, in order of cost:

Renegotiate, accepting that a ransom strip will be valued on a share of the development value uplift rather than on agricultural value. A proportion of the uplift is the conventional starting point in that negotiation, derived from a long-standing valuation case, and it is a convention rather than a rule.

Apply under section 73 to vary the condition, offering an alternative that stays within your control. Where obligations are also in play, check first whether section 106 obligations carry over to a section 73 permission.

Redesign so the works fall inside the site, which normally costs developable area and sometimes units.

Ask the authority to use its own powers, which is a long shot. Authorities can acquire land compulsorily to facilitate development, and they very rarely will for a private scheme.

Alternatives if the condition is refused

Where the authority will not accept a Grampian condition and refuses permission instead, the appeal case is about prospects. Bring the correspondence, the option agreement, the undertaker's confirmation that it can deliver the connection, and any comparable permissions in the area granted on the same basis.

Phasing is the other answer. A scheme that delivers the first phase without the off-site works, with a condition capping occupation until they are in place, gives the authority its protection and you your cashflow. That sort of trade is also what sits behind review mechanisms and deferred contributions, and the viability reasoning behind it is the subject of the Viability Assessment. Where an existing obligation has become the obstacle, discharging a section 106 obligation that no longer serves may be the quicker route than fighting the condition.
