London New-Build Payment Structures: What Gulf Investors Need to Know
Featured Question
Do London off-plan properties offer instalment payment plans like Dubai?
Not in the way Gulf investors typically expect. London concentrates the bulk of the purchase price at two key points — exchange and completion — rather than spreading payments across the build period and beyond. The remaining balance, which is the large majority of the price, is paid in full at completion, whether in cash or via a mortgage.
One phrase that comes up again and again from Gulf and Arab investors enquiring about London is "instalment plan apartments." It's entirely understandable — if your first experience of property investment was in Dubai, where flexible payment schedules stretching across the build period and even beyond handover are standard, that's the mental model you carry into the next market. The trouble is that England and Wales operate under a fundamentally different legal and commercial framework, and misreading it can create serious cash-flow problems.
This article makes no attempt to pitch one market over the other. What it does do is explain, honestly and in plain terms, how money actually moves when you buy a new-build property in London — what resembles an instalment plan, what is categorically different, and what you need to have sorted before you put pen to paper.

How the payment structure for an off-plan London new-build actually works
The purchase of a new-build property in England and Wales follows five sequential stages, each carrying specific financial and legal obligations.
- Stage 1 — Reservation: Once your offer is accepted, you pay a reservation fee. This takes the unit off the market and gives you an exclusive window to complete the legal groundwork. The fee varies considerably depending on the developer and the unit price, and it may be non-refundable if you pull out — read the reservation agreement carefully before signing anything.
- Stage 2 — Pre-Exchange Legal Work: Your solicitor receives the draft contract and supporting documents and begins due diligence. This stage typically runs for 14 to 28 days from receipt of the draft contract. Critically, you are not legally committed at this point — you can still walk away, though you may forfeit the reservation fee.
- Stage 3 — Exchange of Contracts: This is the binding moment. Both parties sign, the contract becomes legally enforceable, and the exchange deposit — typically around 10% of the purchase price, less the reservation fee already paid — is transferred. Pay close attention to how this deposit is held: some developers hold it as agent, which allows them to use those funds, and new-build structural warranties do not provide absolute protection in the event of developer insolvency. Your solicitor should advise on the specific arrangements in the contract.
- Stage 4 — Stage Payments: On longer build programmes, a developer may request additional payments during construction, typically at six-month or twelve-month intervals, with the schedule set out in the reservation agreement. Not every scheme requires these — they vary by developer and project.
- Stage 5 — Completion: The remaining balance is paid in full, along with Stamp Duty Land Tax (SDLT) and all legal fees, and you receive the keys. Buyers are generally notified two to four weeks before the completion date that the build is ready. Make sure your contract includes a Longstop Date — the legally defined latest acceptable date for completion — which protects your rights if the project overruns.
A simple mental map: Reservation → Legal work (14–28 days) → Exchange + deposit (~10%) → Possible stage payments → Completion + full remaining balance.
Is the London exchange deposit the same as an instalment plan?
No — and that distinction matters enormously for any investor coming from a Dubai background.
In London, the two large financial events are exchange and completion. Between them there may be stage payments, but these are a fixed, pre-agreed schedule written into your contract — not an open-ended arrangement. More importantly, the large majority of the purchase price falls due in a single payment at completion, whether you are paying cash or using a mortgage. There is no option to settle gradually after you receive the keys.
A practical point that catches many buyers off guard: on large schemes, a long period can pass between exchange and completion. During that window, you generally cannot obtain a binding mortgage offer, because lenders do not issue offers valid over such extended periods. This adds a layer of financial risk that needs to be managed carefully with a specialist mortgage broker — ideally well before you reach the exchange stage.
What does Dubai offer by comparison? An honest assessment
The differences between these two markets are real and significant, not merely a matter of detail. Glossing over them does investors no favours.
- Dubai construction-phase payment plans: Payments are typically split across the build period and handover, with the specific proportions and timelines varying by developer and project, all set out in the Sale and Purchase Agreement (SPA).
- Dubai post-handover payment plans: These exist and are increasingly common, with some developers allowing a portion of the price to be paid in instalments after the unit is received. They are not universal, however, and terms vary considerably from one scheme to the next.
- Dubai off-plan bank financing: Generally restricted to the handover stage for off-plan properties, which makes developer payment plans the primary mechanism for spreading cost during the build period.
- London — the honest bottom line: Extended post-completion instalment arrangements are not a feature of the London market in any standard sense. The price is paid in full at completion, and that fundamental structure is unlikely to change regardless of how a purchase is planned. Early cash-flow planning or mortgage preparation is not optional — it is an essential part of any purchase strategy.
- What protections apply: Each market has its own contractual protections and its own risks. Ask your solicitor to explain exactly what applies to the specific scheme you are considering before you reserve.
Optivest Note — two common mistakes: Investors moving from Dubai to London often make two mistakes. First, they sign the reservation agreement before their financing or liquidity position is even broadly confirmed, which puts them under uncomfortable pressure when exchange arrives. Second, they assume that "off-plan in London" means payment can be deferred until after handover — an expectation the British market simply does not support in normal circumstances. The fix is straightforward: speak to a mortgage broker before you reserve, not after.
Stamp Duty and completion costs: what you need to budget for
At completion, you are not just paying the remaining purchase price. Several additional costs need to be in your plan from day one.
- Stamp Duty Land Tax (SDLT): Non-UK residents pay a 2% surcharge on top of the standard SDLT rates. A further 5% surcharge applies to the purchase of an additional or investment property — this rate has been in effect since 31 October 2024. For a detailed worked calculation, Optivest's dedicated SDLT guide for overseas and investor purchasers covers the full rate structure.
- Solicitor's fees: These vary with the value and complexity of the transaction. Always ask for a written fee estimate before instructing.
- Land Registry fees: Payable to HM Land Registry on registration of title; the amount scales with the property value.
- Mortgage-related costs: If you are financing the purchase, budget for valuation fees and any lender arrangement fees — these differ by product and lender.
Managing liquidity and currency conversion: details that deserve serious attention
For Gulf investors transacting in dirhams, riyals or dinars, currency movement between exchange and completion is its own risk layer — separate from anything to do with the property market itself.
The exchange deposit is paid at one sterling rate; the completion balance may be paid at a materially different rate, depending on how currency markets have moved in the intervening months or years. A payment that represented a certain sum in your home currency at exchange may cost significantly more — or less — by the time completion arrives. Some investors lock in a rate with a specialist currency provider at or around exchange (this is not something Optivest provides); others prefer to hold sterling from an early stage. Either way, the decision needs to be made deliberately, not improvised when a completion notice arrives.
- Calculate your total sterling requirement upfront: Purchase price + SDLT + legal fees + financing costs = the real number you need to have available.
- Do not assume a last-minute transfer will be straightforward: Particularly if completion falls during a period of economic or currency volatility.
- Treat each stage payment as a separate currency event: Every interim payment has its own timing and its own exchange rate exposure — plan for each one individually.
A pre-reservation checklist for Gulf investors
Before you sign a reservation agreement on a London new-build, work through this list.
- Have you spoken to an FCA-authorised mortgage broker to understand how much finance you can access and on what terms — before committing to anything?
- Have you read the reservation agreement in full, including the conditions under which the fee is and is not refundable?
- Have you appointed a UK property solicitor who is experienced with non-resident purchasers and is entirely independent from the developer's legal team?
- Have you asked to see the full stage payment schedule (if applicable), the anticipated completion date, and the Longstop Date?
- Do you understand exactly how your exchange deposit will be held after contracts are exchanged, and what protections apply?
- Have you budgeted for SDLT and all completion costs on top of the purchase price — not as an afterthought?
- Have you thought through your currency conversion strategy for each payment date?
Frequently asked questions
Are there post-handover payment plans in London like in Dubai?
Generally, no. The UK market does not routinely offer extended payment plans that continue after a property is handed over — that is a feature associated primarily with certain Dubai developers. The outstanding balance is due in full at completion, paid either in cash or via a mortgage. Rare exceptions may exist in specific schemes or through bespoke arrangements, but they are not a standard feature of the market and should not be assumed as part of any planning.
When exactly do I need my mortgage or full funds to be in place?
Your financing needs to be clearly arranged before completion. The specific complication with off-plan purchases is that completion may be a long period after exchange — and lenders generally do not issue binding mortgage offers valid for such extended periods. For this reason, the practical approach is to work with a mortgage broker before exchange to establish your borrowing capacity in principle, then revisit and formalise the offer as you approach completion. Do not leave this until the completion notice arrives.
What happens if the project is delayed past the expected completion date?
Standard UK off-plan contracts include a Longstop Date — a defined latest date by which completion must occur. If the developer fails to complete by that date, the buyer typically has the right to rescind the contract and recover deposits paid. The precise mechanics of this right, and how it is structured in your specific contract, is something your solicitor must review and confirm before exchange. Construction delays are a reality in any market; London is not immune.
Does the payment structure differ if I'm buying in cash rather than with a mortgage?
The early stages — reservation, exchange deposit, any stage payments — are identical whether you are a cash buyer or using finance. The difference emerges at completion: a cash buyer transfers the balance directly through their solicitor, while a mortgage buyer's lender releases funds to the solicitor and the transaction settles on the same day. In planning terms, a cash buyer has greater flexibility but is committing a larger pool of liquid capital to a single asset — a trade-off worth considering carefully.
Can a non-resident Gulf national get a mortgage in London?
Yes, non-resident buyers can access UK mortgage finance, but the conditions differ from those available to UK residents. Fewer lenders operate in this segment, loan-to-value ratios tend to be more conservative, and income verification requirements are typically more stringent. Working with a mortgage broker who has direct experience with international buyer profiles — which is part of what Optivest does as an FCA-authorised broker — saves considerable time and avoids approaches to lenders unlikely to consider the application.
Is Stamp Duty included in the exchange deposit?
No. SDLT is a separate cost paid at completion and forms no part of the exchange deposit. Non-resident buyers face the 2% non-resident surcharge on top of standard rates, and the additional property surcharge of 5% has applied since 31 October 2024. On higher-value London properties, these combined surcharges represent a material sum that must be planned for well in advance, not discovered at completion.
