Two Keys, One Door: Planning Consent and the Restrictive Covenant Trap in 2026

A homeowner receives a favourable decision notice, instructs a builder, and then discovers that the land itself carries a private restriction against the very development just approved. The sequence is common enough to justify a standing warning in any property transaction: planning permission and private property rights are separate systems, and one does not cure the other. The council may have decided that a scheme is acceptable in planning terms. It has not decided that the owner has the right to carry it out.

The consent is only half the permission

Planning permission regulates the development and use of land under the public planning regime. A restrictive covenant is a private law obligation, usually created in a transfer or conveyance, which limits what an owner may do with the land for the benefit of another parcel or another party. The local planning authority has no power to waive it, vary it or declare it unenforceable. A grant of planning permission is therefore not a defence to a breach, and it does not persuade a court that the covenant should be ignored.

The practical consequence is that a project can be fully consented and still be unbuildable without the agreement of whoever benefits from the covenant. Enforcement may take the form of an injunction to stop works, a claim for damages, or both. For a buyer, the risk is not merely legal cost; it is a site that cannot be used as intended after money has been committed.

Where covenants hide in a 2026 transaction

Restrictive covenants are most often found in the charges register of a registered title, but the register entry may be brief and may refer to a transfer containing the full wording. A buyer's solicitor should read the underlying deed, not merely the register summary. Older unregistered titles, estate transfers, management schemes and development plots can produce layers of restrictions, some of which have long since been forgotten by the parties who imposed them.

Due diligence should include the official copy of title, the transfer or conveyance in which the covenant was created, replies to standard enquiries, and any management company or estate documentation. Planning history is useful context but is not a substitute. A property may have had planning permission for an extension in the past without the covenant point having been tested, or the works may have proceeded in breach without complaint.

The restrictions that catch residential projects

The wording matters more than the label. Common examples include covenants not to erect more than one dwelling on the land, not to use any building except as a private dwellinghouse, not to carry on a trade or business, not to alter the front elevation, not to erect fences above a certain height, and not to build forward of an established building line. Some restrict outbuildings, annexes, separate kitchens or additional windows overlooking neighbouring land.

These can defeat schemes that planning would readily approve. A rear extension may conflict with a restriction on building lines. A family annexe may conflict with a single-dwelling restriction. A home office or holiday let may conflict with a business-use covenant. Permitted development rights are irrelevant to the private covenant question, as are listed building consent and conservation area consents. Each consent regime addresses a different legal concern.

Planning silence is not private permission

It is sometimes assumed that if the council does not object, or if no enforcement action follows, the covenant has lost its force. That is not the correct analysis. The beneficiary of a covenant may be a neighbour, a former landowner, a management company or an estate trustee, and their interests are not represented by the planning authority. Delay, acquiescence or informal tolerance may become relevant in a particular dispute, but they do not automatically extinguish the restriction.

For developers, the point is particularly acute where a site is assembled from several titles. One parcel may be free of restrictions while an access strip or garden plot is not. A consent that relies on the restricted land for access, parking, drainage or amenity can be vulnerable even if the main building plot is clear.

The routes to resolution

The first route is negotiation. The person or body entitled to the benefit of the covenant may agree to release it or vary its terms by deed. A payment may be required, and the release should be documented properly and, where appropriate, registered. This is often the cleanest outcome where the beneficiary is identifiable and willing to engage.

Statutory modification or discharge

Where agreement cannot be reached, an application can be made to the Upper Tribunal (Lands Chamber) under section 84 of the Law of Property Act 1925 for the modification or discharge of a restrictive covenant. The statutory grounds are narrow and fact-specific. They include cases where the covenant is obsolete, where it impedes the reasonable use of the land without securing practical benefit to the beneficiary, and certain other limited circumstances. The tribunal will consider evidence about the history of the restriction, the character of the neighbourhood and the effect on those entitled to enforce it. This is not a quick or inexpensive route, and it should be assessed before exchange rather than after a builder has been instructed.

Indemnity insurance and its limits

Restrictive covenant indemnity insurance is often mentioned as a solution. It can be useful where the beneficiary is unknown or untraceable, where there has been no breach and no approach to the beneficiary, and where the policy is put in place before the restricted works begin. It generally covers the cost of defending a claim and any damages or diminution in value, subject to the policy terms.

It does not remove the covenant. It does not guarantee that an injunction will be refused. It will not normally be available where the breach is already known, where the insurer considers the risk to be pre-existing, or where the buyer has opened negotiations for a release. A buyer should not treat an indemnity policy as a substitute for a release if the beneficiary can be found and a modification application is realistic.

A due diligence sequence for buyers and developers

Before exchange, obtain the official copy of title and read the charges register in full. Ask for the underlying transfer or conveyance and any estate or management documentation. Check whether the intended scheme, including access and services, depends on land affected by a restriction. Ask the seller what they know about past releases, breaches or complaints. Take specialist advice on the wording before committing to a planning application, not after consent is granted. If insurance is proposed, arrange it before exchange and before any breach, and ensure the policy is not undermined by prior knowledge or negotiations.

For anyone already owning a restricted property, the same discipline applies in reverse: retrieve the deeds, identify the beneficiary, and decide whether negotiation, statutory modification or a redesign is the realistic path. Planning consent may open the door to development, but the covenant is a second lock. In 2026, the prudent approach is to check both keys before turning either.
