A step-by-step guide - How to buy property in London from Thailand

London continues to attract property investors from across the world, including buyers based in Thailand. The capital city’s transparent framework and strong rental market make it a popular choice amongst discerning landlords.

For Thai investors, the UK property buying process can differ from what they are familiar with locally. Knowing how each stage within this process works can make the experience far more straightforward. In this guide, we explain how to buy London property from Thailand and what to expect during this process.

Step 1: Arranging finance

Before beginning the property search, it is important to understand your financial position. Ask yourself how much capital you intend to allocate to the property purchase and if you’ll be opting for any mortgage. Questions you can ask yourself:

How much money can I borrow?

How much cash capital will I be able to deploy?

What is my preferred loan-to-value ratio?

If you plan to opt for a mortgage, it is best to speak with a lender. Lenders can usually indicate how much they would be willing to lend before you select a property.

Step 2: Set a budget

The purchase price is one component of a London property transaction. Overseas buyers also need to account for additional costs related to the acquisition. This includes Stamp Duty Land Tax (including non-resident surcharge), legal fees and local authority searches, survey and valuation fees, mortgage arrangement and broker fees (if applicable), financing costs and ongoing service charges for leasehold properties.

Also, ensure you consider currency planning between THB and GBP.

Step 3: Narrow down requirements

London is a large city made up of 32 boroughs, each with its own property market features, price ranges and tenant profiles. Narrowing your search to specific areas early on helps focus the search. The features typically evaluated are

Area and transport connectivity.

Number of bedrooms and bathrooms.

Concierge and on-site lifestyle amenities.

Parking availability.

New build vs period property.

Rental suitability, if the purchase is investment-focused.

For instance, a two-bedroom apartment with two bathrooms typically appeals to a wider tenant pool in central London.

Step 4: Search and view properties

Once you define the criteria, you can begin shortlisting the properties. As a Thai buyer, you have the option to view properties in person when visiting London, conduct virtual viewings - our team will arrange that on WhatsApp or Zoom, as per your availability and also share detailed photography and reporting of the property options.

Step 5: Submitting an offer

When you find a suitable property, the next step is to submit an offer to the seller. Your property advisor will recommend an appropriate offer based on the current market conditions and recent sales within the area.

In England, an offer does not immediately create a legally binding contract. The property is only considered ‘sold subject to contract’ while the legal work begins.

Step 6: Instruct your solicitor

Once your offer is accepted, you will need to formally instruct a UK solicitor. In England, the solicitor plays a central role in safeguarding your interests as a buyer. They review the legal title, assess the lease, order local authority searches and raise any necessary enquiries with the seller’s legal team. They also help confirm what is included in the sale, for instance, fixtures, fittings and appliances. If you are buying property in London from Thailand, you will also need to complete identity checks and provide documentation confirming the source of funds.

Step 7: Offer acceptance and Memorandum of Sale

Once the basic terms are agreed, the seller’s agent issues a Memorandum of Sale. This document is essentially a written summary of the agreed-upon terms. It also includes the prices, the parties involved, the solicitors acting on each side and the proposed timeline. Although this document is not legally binding, it clarifies that the property is marked sold subject to contract at this point.

Step 8: Conveyancing

Conveyancing refers to the legal checks conducted on the property before the purchase is finalised. The buyer’s solicitor, during this stage, carefully examines the legal documentation, reviews the title and highlights any restrictions or obligations linked to ownership. For leasehold deals, the lease agreement and service charge arrangements are also reviewed.

Step 9: Valuation and survey

For mortgage purchases, the lender will appoint a valuer and a formal mortgage offer will be used. Buyers also have the option to commission an independent survey to assess the structural condition of a completed property.

Step 10: Exchange of contracts

Buyers must transfer 10% deposit to the seller’s account when exchanging contracts; both parties will agree upon a completion date and become contractually committed. In the event of withdrawal after this stage, financial penalties may apply.

Step 11: Snagging

For off-plan or a newly completed property, a pre-completion inspection is carried out. A snag list helps identify problems like cosmetic defects, installation issues, incomplete work, etc. Once the issues are submitted, developers are required to rectify the issues recorded before or shortly after completion.

Step 12: Completion

At this stage, remaining funds are transferred to the seller.

Legal ownership is formally transferred to you, as the buyer.

Keys are released.

Congratulations! You are now the registered owner of a property in London.

Step 13: Stamp Duty Land Tax

Stamp Duty Land Tax must be calculated and filed shortly after completion. As a non-UK resident, a surcharge will apply to your tax. The rates for the same vary based on property value and ownership structure. Accurate SDLT forecasting needs to be conducted during budget planning.

Step 14: Warranties for new-build purchases

New homes typically include a 10-year structural warranty, a developer defect liability period and appliance warranties. Understanding warranty coverage is important for long-term asset protection.

Step 15: Handover and key collection

At handover, you are required to review the snagging items, record utility meter readings and confirm certificates for Gas Safety and EPCs. Once all is clear, the keys are formally handed over to your appointed solicitor.

Step 16: Lettings and management (next steps)

For Thai investors not residing in London, professional management ensures reliable tenant sourcing, rent collection and transfers, maintenance coordination, tax compliance and service charge and ground rent payments.

What are the key differences between Thailand and the UK property buying processes?

If you are assessing buying a property in London from Thailand, some structural differences are important to consider:

Transactions in the UK become legally binding only at the exchange of contracts.

Solicitors play a central role in due diligence.

Buyers are required to pay Stamp Duty Land Tax on completion of the purchase.

Freehold and leasehold property ownership structures differ from Thai condominium law.
