Buying a new home in London can feel exciting and overwhelming at the same time! Did you know that the majority of buyers are unaware of the step-by-step process from developer release to completion? For foreign buyers and first-time homeowners, navigating the London property market requires careful planning and expert advice.

At Capital Homes, we guide buyers through each stage of the new homes sales process, ensuring you understand the timing, costs, and key considerations. From the moment a developer releases a property to the final completion, every step is crucial to securing your dream home in London. In this article, we break down the process and highlight why working with a trusted estate agent makes all the difference.

1. Developer Release: First Access to New Homes

The journey begins with a developer release, where properties in a new development are made available for sale. Developers often release homes in phases, giving buyers early access to the best units. At this stage, buyers can view floor plans, pricing, and optional upgrades.

Early access is particularly important in high-demand areas like Hyde Park, Canary Wharf, and Nine Elms. Properties in central London sell quickly, so understanding release dates and developer terms is key for securing your preferred home.

2. Reservation and Deposit

Once you identify a property, the next step is to reserve it. This typically involves paying a reservation fee, which secures the property while legal contracts are prepared.

During this stage, buyers should review the developer’s specifications carefully, including floor plans, finishes, and optional features. Capital Homes advises clients on how to navigate these choices, ensuring the home matches your lifestyle and investment goals.

3. Contract Exchange and Legal Checks

After reservation, the buyer’s solicitor will review the contract and carry out legal checks. These include:

  • Verifying the title and land ownership
  • Reviewing warranties and guarantees
  • Checking planning permissions and compliance

Contracts are exchanged once all checks are complete, and a deposit (often 10% of the purchase price) is paid. This step legally binds the buyer to the property and protects both parties.

4. Construction and Progress Updates

While the property is being built, developers provide regular progress updates. Buyers can monitor construction milestones, expected completion dates, and any changes to the schedule.

Modern new builds often include smart-home technology, energy-efficient features, and high-quality finishes. Capital Homes keeps clients informed during this stage, ensuring transparency and peace of mind.

5. Completion and Handover

The final step is completion, where the remaining balance is paid and the property officially becomes yours. Buyers receive the keys, move in, and begin enjoying their new home.

Completion is also the point where warranties and guarantees come into effect, protecting buyers from structural issues or defects. Capital Homes coordinates with developers, solicitors, and mortgage advisors to make this process seamless for clients.

What is included in a new build warranty?

Do I need a mortgage before reserving a new build?
While it is advisable to have mortgage approval in principle, many buyers reserve their property first and finalise financing before exchange. Capital Homes works with trusted mortgage advisors to ensure you are fully prepared.

Are there any additional costs to consider?
Yes. Buyers should budget for legal fees, stamp duty, and potential optional upgrades offered by the developer. Capital Homes helps you understand all costs upfront, avoiding surprises.
