Can I Sell My Off-Plan Property Before Completion UK?

How to sell or assign an off-plan property before completion, including developer consent, contract restrictions and tax considerations

If you have purchased an off-plan property in the UK and want to sell it before the development is completed, you may have options. However, you cannot automatically sell the property in the same way as someone selling a completed home.

If you have exchanged contracts but have not yet completed, you may instead need to transfer your contractual rights to another buyer through an assignment or use another pre-completion structure. HMRC specifically recognises pre-completion transactions where the original purchaser enters into an arrangement allowing another person to acquire the subject matter of the original contract.

Can You Sell an Off-Plan Property Before Completion?

Potentially, yes.

The first thing to establish is what your original purchase contract says about assignment or transferring your contractual position.

Your contract may:

  • Allow assignment without the developer's consent

  • Require written consent from the developer

  • Allow assignment only within a particular period

  • Charge an administration or assignment fee

  • Restrict assignment altogether

  • Require the proposed buyer to meet certain conditions

  • Keep you liable for certain obligations even after the transfer

This is why you should have the original contract reviewed before advertising the property or agreeing terms with another buyer.

What If You Have Already Exchanged Contracts?

This is particularly important.

In England and Wales, an accepted offer is generally not legally binding until contracts are exchanged. Once contracts have been exchanged, the purchase becomes legally binding.

Therefore, if you have exchanged contracts on an off-plan apartment, you normally cannot simply tell the developer that you no longer want the property.

Instead, you may need to find a legally permitted way to transfer your contractual position.

For example, an assignment could allow another purchaser to step into your contractual position, subject to the terms of the original agreement and any required developer consent.

How Does an Off-Plan Assignment Work?

A typical transaction may look like this:

You originally agree to buy an apartment for £300,000.

Before completion, you find another buyer willing to take over the purchase.

The developer's contract permits assignment subject to consent.

Your solicitor reviews the proposed transaction and prepares or reviews the appropriate legal documentation.

The developer approves the new buyer.

The contractual rights are transferred according to the agreed structure.

The new buyer ultimately completes the purchase in accordance with the relevant contracts.

The exact legal structure can vary, so the transaction should be handled by a solicitor experienced in property assignments and new-build transactions.

Does the Developer Have to Let You Sell?

No.

Your ability to assign the purchase contract depends on the terms you agreed with the developer.

Some developers permit assignments under specified conditions, while others restrict them. There may also be contractual deadlines or administrative charges.

Before approaching a buyer, check:

  • The assignment clause

  • Whether developer consent is required

  • The assignment deadline

  • Any administration fee

  • Whether the developer can reject the proposed buyer

  • Whether your deposit can be transferred

  • Whether you remain liable for any part of the original contract

  • Whether the developer has imposed restrictions on marketing or resale

Do not assume that an estate agent advertising the property means the assignment itself is legally permitted.

Can You Make a Profit From Selling Before Completion?

Potentially.

For example, you might have agreed to buy an off-plan apartment for £300,000. If demand increases and another buyer is prepared to pay more for your contractual position, you could potentially receive an assignment premium.

However, the amount you actually make is not simply the difference between the property's original price and its current market value.

You may have to account for:

  • Developer assignment fees

  • Solicitor fees

  • Agent fees

  • Tax

  • Mortgage or finance costs

  • Your original deposit

  • Other transaction costs

The contract and tax treatment should therefore be reviewed before you calculate your expected profit.

What About SDLT?

Stamp Duty Land Tax can become relevant to an assignment or other pre-completion transaction in England.

HMRC has specific rules for pre-completion transactions, including assignments and subsales. The tax treatment depends on the precise structure and circumstances.

There can also be SDLT consequences where a transaction is substantially performed before formal completion.

This means you should not agree an assignment premium without first understanding the potential tax consequences.

A solicitor or specialist property tax adviser can calculate the relevant position based on your transaction.

What If the Developer Refuses the Assignment?

If your contract requires the developer's consent and consent is refused, you should not simply proceed as though the transfer has been completed.

Depending on the contract and circumstances, your solicitor may investigate alternatives such as:

  • Negotiating consent with the developer

  • A variation to the original contract

  • A novation

  • A subsale structure

  • Completing the original purchase and selling afterwards

  • Negotiating another contractual solution

The appropriate option depends on the wording of the original contract and the developer's position.

Can You Sell the Property After Completion Instead?

Yes, but that is legally different.

Once you have completed the purchase, you own the property and can generally sell it subject to the normal legal, mortgage, lease and title requirements.

Before completion, however, you may only have contractual rights rather than ownership of the completed property.

That distinction is particularly important when dealing with off-plan apartments.

What Should You Do Before Trying to Sell?

Before marketing an off-plan property before completion, ask your solicitor to review the purchase contract.

You should establish:

  1. Whether assignment is permitted.

  2. Whether developer consent is required.

  3. Whether an assignment fee applies.

  4. Whether there is a deadline for assignment.

  5. Whether the developer can reject the proposed buyer.

  6. What happens to your original deposit.

  7. Whether you remain liable after assignment.

  8. What SDLT or other tax consequences could arise.

  9. What legal documents are required.

  10. Whether the proposed transaction is actually an assignment, subsale, novation or another structure.

This can prevent you from finding a buyer and agreeing a price before discovering that the original contract does not allow the transaction.

How Fraser Bond Can Help

Fraser Bond can support investors and property owners with the commercial side of off-plan property transactions, including property investment analysis, development consultancy and transaction coordination.

Where an assignment, contract transfer or other legal mechanism is involved, the legal documentation should be handled by a suitably qualified UK property solicitor or conveyancer. Fraser Bond can work alongside professional advisers to support the wider property transaction.

Final Check Before Selling an Off-Plan Property

Selling an off-plan property before completion can be possible, but it is not automatically the same as selling a completed property.

The key question is what your original purchase contract allows.

If assignment is permitted, you may be able to transfer your contractual position to another buyer. If it is restricted, you may need developer consent or an alternative legal structure.

Before accepting money, signing an agreement with another buyer or marketing the property as available for assignment, have the original contract reviewed by a qualified property solicitor. This is particularly important where a substantial assignment premium, developer fee, mortgage or SDLT liability is involved.
