Buying in London: What You Need to Know

Article summary: London’s property market is one of the most complex in the world. From leasehold arrangements and building safety requirements to stamp duty thresholds and long chains, buyers face a unique set of challenges that can catch even experienced movers off guard. Understanding the legal landscape before you start can save you significant time, money and stress. 

London’s property market moves fast. High prices, complex leasehold arrangements and fierce competition mean there’s plenty that can catch buyers off guard. 

Knowing what to expect before you start can save you time, stress and money. 

Here are some key conveyancing tips for London buyers and sellers. 

1. Understand Leasehold and Share of Freehold Complexities 

Much of London’s housing is leasehold. You own the property for a set number of years, but the land is owned by a freeholder, with service charges and ground rent usually payable. 

Lease length matters. Short leases, typically under 80 to 90 years, can significantly increase the cost of extending and may affect your ability to secure a mortgage. Following the Leasehold and Freehold Reform Act 2024, extending a lease has become more streamlined, but the premiums involved remain a major financial consideration. 

Share of freehold arrangements are also common, giving you joint ownership of the building alongside other flat owners. This provides more control over building management but comes with its own rights and obligations. 

Be aware that managing agents can be slow to provide management packs, which can materially slow a transaction. This is covered in more detail in the delays section below. 

2. Understand Building Safety Act and EWS1 Requirements 

If you are buying a flat in London, building safety is now a central part of the conveyancing process. Under the Building Safety Act 2022, lenders are particularly sensitive to cladding and fire safety issues. 

You may need to provide an EWS1 form confirming the external wall system meets safety standards. Where remediation is needed, your conveyancer should clarify who is responsible for costs before you complete. 

3. Factor in Management and Local Authority Timelines 

Delays in London transactions often come from third parties rather than the council. One of the most consistent bottlenecks is the receipt of LPE1 forms and management information from landlords and managing agents, often a more significant cause of delay than local authority searches. 

Proactive communication between your estate agent, mortgage broker and conveyancer from the outset can make a real difference to how smoothly things progress. 

4. Be Aware of Conservation Areas and Listed Buildings 

Many London neighbourhoods, particularly historic districts like Kensington & Chelsea, Westminster and Hackney, fall under conservation regulations. If you are buying a listed building, even internal alterations can require specific consent. A lack of historic consents for past works can create complications on resale and with mortgage lenders. Your conveyancer should carry out thorough checks before you proceed. 

5. Prepare for High Property Values and Stamp Duty Land Tax 

London prices often push transactions into higher SDLT bands. SDLT works in tiers, so you pay different rates on each portion of the price. 

For example, on a property costing £1 million, you’d pay: 

• 0% on the first £125,000 

• 2% on the next £125,000 

• 5% on the portion from £250,001 to £925,000 

• 10% on the remaining £75,000 

Additional property purchases carry a 5% surcharge. As of April 2026, the 2% non-UK resident surcharge continues to apply, which combined with the additional property surcharge can result in 7% above standard rates for overseas investors. 

First-time buyer relief has important limits in London. The nil-rate threshold is £300,000 and relief only applies to properties up to £500,000. Buy at £550,000 and you lose the relief entirely, paying standard rates on the full amount. SDLT also becomes more complex for main residence replacements, company purchases and mixed-use properties. Early, tailored advice is essential. 

6. Plan for Complex Property Chains 

London transactions frequently involve long chains. Delays can stem from mortgage approvals, third-party responses or seller-side issues. Proactive communication between your estate agent, mortgage broker and solicitor is often the single biggest factor in whether a chain holds together.
