First-Time Home Buyer Guide for London: Everything You Need to Know Before You Buy

London's property market operates differently from the rest of England. Prices are higher, competition moves faster, and the legal structures around flats, particularly leasehold ownership, add layers of complexity that first-time buyers elsewhere rarely encounter. Getting a clear picture of what you are walking into before you start viewing properties will save you time, money, and a great deal of stress.

What Prices Actually Look Like Right Now

As of September 2026, the average property price across Greater London sits at roughly £530,000, though that figure masks enormous variation by borough and property type. In inner east London boroughs such as Hackney, prices have moved considerably over the past two years. For a detailed picture of how values have shifted, the article on house price changes in Hackney between 2024 and September 2026 gives borough-level data worth reading before you set your budget.

Further out, outer east and south-east London boroughs offer more accessible entry points. In areas such as Walthamstow, a three-bedroom terraced house was asking between £550,000 and £650,000 in September 2026, depending on condition and proximity to the Victoria line. Woolwich and Catford sit at lower price points still, with one and two-bedroom flats often available below £350,000. These are not the cheapest properties in England, but they are the most realistic starting points for many first-time buyers in the capital.

Freehold vs Leasehold: The Distinction That Changes Everything

The majority of flats in London are sold leasehold, meaning you buy the right to occupy the property for a fixed term, often 99 or 125 years, but you do not own the building or the land beneath it. Freehold ownership, where you own the property and the land outright, is more common with houses. For a first-time buyer, this distinction matters enormously because leasehold properties come with annual service charges, ground rent obligations, and the risk of a lease that has shortened to a point where it becomes difficult to mortgage or resell.

Always check the remaining lease length before making an offer on a flat. Most mortgage lenders require at least 70 to 85 years remaining at the end of the mortgage term, so a lease with 85 years left on it today may already be too short for a 25-year mortgage. Service charges on London flats can range from a few hundred pounds per year in smaller mansion blocks to several thousand pounds annually in purpose-built developments with concierge services and lifts. The article on service charges and ground rent on leasehold flats in Canary Wharf gives a concrete example of what these costs look like in practice, and the principles apply across the city.

2. Getting Your Finances in Order Before You Search

Sorting your finances before you start viewing properties is not optional in London. Sellers and their agents will not take an offer seriously unless you can demonstrate that your mortgage is already arranged in principle. In a market where well-priced properties in sought-after postcodes can receive multiple offers within days of listing, arriving unprepared costs you properties.

How Much Deposit Do You Actually Need in London

The minimum deposit for most residential mortgages in the UK is five percent of the purchase price, but in London that figure takes on a different weight. On a £400,000 flat, five percent means £20,000 upfront, and that is before legal fees, survey costs, and stamp duty. A ten percent deposit of £40,000 opens up better mortgage rates and gives you a meaningful buffer against any valuation shortfall, where the lender values the property below the agreed purchase price and you must cover the difference.

Beyond the deposit, budget for the following purchasing costs as a first-time buyer in London in 2026: solicitor or conveyancer fees typically run between £1,500 and £3,000 including disbursements; a HomeBuyer Report survey costs approximately £500 to £900 depending on property size; a full structural survey for older or unusual properties runs £800 to £1,500; and mortgage arrangement and broker fees vary but budget at least £500 to £1,000. These costs are paid before or at completion and cannot be added to your mortgage.

The government's Help to Buy equity loan scheme closed to new applicants in 2023, but several alternatives exist for first-time buyers in London in 2026. The Mortgage Guarantee Scheme and shared ownership routes through housing associations remain active options. Forbes Advisor UK has a thorough breakdown of Help to Buy alternatives for first-time buyers in London that is worth reading before you decide which route suits your situation.

Mortgage in Principle: Why You Need One Before Viewing Homes

A mortgage in principle, sometimes called an agreement in principle or decision in principle, is a written statement from a lender confirming it would, in principle, lend you a specific amount based on your income, outgoings, and a soft credit check. It is not a formal mortgage offer, but it signals to estate agents and sellers that you are a credible buyer. Most agents in London will ask to see one before they book you a viewing on a property that has received strong interest.

Use a whole-of-market mortgage broker rather than going directly to your bank. A broker searches across dozens of lenders and can access rates not available on the high street. They will also flag any issues with your credit file or income documentation before you find a property you want, giving you time to resolve them. In London, where the difference between a two percent and a two-and-a-half percent mortgage rate on a £400,000 loan amounts to roughly £100 per month, a broker's fee pays for itself quickly.

3. Stamp Duty Land Tax Relief for First-Time Buyers

Stamp Duty Land Tax is one of the largest upfront costs in any London property purchase, but first-time buyers receive meaningful relief that reduces the bill significantly on properties up to £500,000. Understanding exactly how the relief works, and where it cuts off, is essential before you set your maximum budget.

How the First-Time Buyer Relief Works in September 2026

As of September 2026, first-time buyers in England pay no stamp duty on the first £425,000 of a property's purchase price, and five percent on the portion between £425,001 and £625,000. If the property costs more than £625,000, the standard stamp duty rates apply and you lose the first-time buyer relief entirely. This threshold is particularly relevant in London, where a large number of properties sit in the £450,000 to £625,000 range.

To illustrate: on a £500,000 purchase, a first-time buyer pays five percent on the £75,000 above the £425,000 threshold, which equals £3,750. A non-first-time buyer on the same property would pay £12,500 under the standard rates. That is a saving of £8,750, which is meaningful against the other costs of buying in London. For a worked example at the £650,000 price point, the dedicated article on stamp duty on a £650,000 property for a first-time buyer in London in 2026 walks through the calculation in full.

What Counts as a First-Time Buyer Under HMRC Rules

HMRC defines a first-time buyer as someone who has never previously owned a residential property anywhere in the world, including properties inherited or received as a gift. If you are buying jointly, both buyers must meet this definition for the relief to apply. Someone who previously owned a property abroad, or who inherited a share of a property even without living in it, may not qualify. Your solicitor will ask you to confirm your status as part of the SDLT return, so be accurate: a false claim is a criminal offence.

4. Searching for a Property and Making an Offer

The search phase is where most first-time buyers in London spend the most time and feel the most uncertainty. Properties in popular east and south-east London postcodes can go under offer within a week of listing, sometimes faster. Knowing how to search efficiently and how to structure an offer that sellers take seriously shortens this phase considerably.

How to Structure a Competitive Offer in London

A competitive offer in London is not just about the number. Sellers weigh your position, your chain status, and your readiness to proceed alongside the price. As a first-time buyer you have one significant advantage: you have no property to sell, which means no chain below you and no risk of your purchase collapsing because your buyer pulled out. Lead with this when you make your offer.

Before offering, research comparable sales in the same street or block using the Land Registry's sold prices data, which is publicly available and updated regularly. If a flat in the same building sold for £310,000 six months ago and the current asking price is £340,000, you have a concrete basis for negotiation. Ask the estate agent how long the property has been listed, whether there have been any previous offers, and what the seller's preferred timeline for completion is. Matching your offer to their preferred completion date can be as persuasive as a higher number.

Commute matters enormously in London and should be a core part of your search criteria, not an afterthought. A flat in Leyton, for example, sits on the Central line and offers a journey to Liverpool Street of under 15 minutes. The article on the commute from Leyton to the City of London by tube is a useful reference if you are weighing east London options against your workplace location.

Surveys and What They Reveal About Older London Stock

London's housing stock is old. A large proportion of the terraced houses and Victorian mansion block conversions that make up the entry-level market were built between 1880 and 1940, and many have not been significantly updated since. A mortgage valuation, which the lender carries out for its own purposes, is not a survey. It tells you what the lender thinks the property is worth; it does not tell you what condition it is in.

Commission at minimum a HomeBuyer Report (RICS Level 2) on any property you are buying. For Victorian terraces, ex-local authority houses, or any property showing signs of damp, cracking, or roof issues, upgrade to a full structural survey (RICS Level 3). The additional cost of £300 to £600 is insignificant compared to discovering after completion that the roof needs replacing at a cost of £8,000 to £15,000. Survey findings also give you a legitimate basis to renegotiate the price or ask the seller to carry out remedial work before exchange.

5. From Offer Accepted to Completion: The Legal Process

Once your offer is accepted, the legal process begins. In England, an accepted offer is not legally binding: either party can withdraw at any point before exchange of contracts without penalty. This period, known as the conveyancing process, is where first-time buyers often feel most out of their depth.

What Conveyancing Involves and How Long It Takes

Conveyancing is the legal transfer of property ownership from seller to buyer. Your solicitor or licensed conveyancer will carry out searches on the property, review the title deeds, raise enquiries with the seller's solicitor, check the lease if applicable, and prepare the contract. Once all parties are satisfied, contracts are exchanged and a completion date is set. On the completion date, funds transfer and you receive the keys.

In London, the average time from offer accepted to completion currently runs between 12 and 20 weeks, though leasehold purchases, properties in chains, or cases involving complex title issues can take longer. The full breakdown of what happens at each stage and where delays typically occur is covered in the article on the conveyancing process timeline in London from offer to completion, which is essential reading before you appoint a solicitor.

Choose your solicitor before your offer is accepted so you can instruct them immediately. Ask for a fixed-fee quote that includes all disbursements: search fees, Land Registry fees, and bank transfer charges. Avoid the cheapest option available; a slow or inexperienced conveyancer in a London transaction can cost you the property if the seller loses patience and accepts another offer.

Common Delays and How to Avoid Them

The most common causes of delay in London conveyancing are: slow local authority searches, which can take four to eight weeks in some boroughs; missing or defective title documents on older properties; unresolved lease issues such as ground rent arrears or missing building insurance certificates; and mortgage offer delays caused by lender backlogs. You can mitigate most of these by instructing your solicitor to order searches immediately after your offer is accepted, chasing your mortgage lender for a formal offer within two weeks of application, and responding to your solicitor's enquiries within 24 to 48 hours rather than letting them sit.

New-build properties in London, such as those currently being developed in the Woolwich and Royal Arsenal area, operate on a slightly different timeline because the developer's solicitors often have the legal pack ready before the property is complete. However, new builds carry their own risks around completion delays and snagging. The article on new residential developments in Woolwich and the Royal Arsenal in 2026 gives useful context if you are considering that route.
