Conveyancing fees are one of the most commonly underestimated costs in a London property transaction. Most buyers focus on deposit, stamp duty, and mortgage costs — and then receive a conveyancing bill that is significantly higher than they expected. This is particularly true in London, where higher property values, a high proportion of leasehold properties, and greater legal complexity push conveyancing costs well above the national average.
The average cost of conveyancing in London is £1,060 for sellers and £3,074 for buyers in 2026, according to CompareMyMove data. London buyers pay 76% more than the national average — and for leasehold properties, which represent the majority of flat transactions in the capital, the costs are higher still. Understanding what drives this gap, what the bill includes, and how to keep costs under control is essential preparation for any London property transaction.
What Conveyancing Fees Cover
Your conveyancing bill has two distinct components. Understanding both prevents the most common budgeting mistake — quoting for legal fees alone and then being surprised by disbursements at completion.
Legal fees are the solicitor or licensed conveyancer’s charge for their time, expertise, and professional responsibility for the transaction. This covers:
- Reviewing the contract and title documentation
- Raising and responding to enquiries with the other party’s solicitor
- Reporting to you on the property’s legal position
- Exchanging contracts and managing completion
- Registering the title at the Land Registry after completion
Legal fees for a standard London freehold purchase typically run £800 to £1,500 plus VAT. For leasehold purchases — which cover the majority of London flats — add approximately £300 to £500 for the additional legal work involved in reviewing the lease, service charge accounts, and management pack.
Disbursements are third-party charges that your solicitor pays on your behalf and passes through to you. These are not the solicitor’s profit — they are fixed costs imposed by third parties including the Land Registry, local authorities, and search providers. The main disbursements for a buyer are:
- Local authority search: £100 to £300 depending on the London borough. Reveals planning history, road proposals, compulsory purchase orders, and other local matters affecting the property.
- Water and drainage search: £30 to £50. Confirms drainage connections and whether any public sewer crosses the property.
- Environmental search: £30 to £50. Identifies flood risk, contaminated land, and ground stability issues.
- Land Registry fee: £20 to £500 depending on the purchase price. Charged by HM Land Registry to register the new ownership.
- Stamp Duty Land Tax: not technically a disbursement but collected and filed by your solicitor at completion.
- Electronic bank transfer fee: £20 to £45 per transfer for secure transmission of completion funds.
- Anti-money laundering and ID checks: £20 to £50. Legally required verification of all parties.
Total disbursements for a London buyer typically run £400 to £700 for a standard freehold transaction, rising to £600 to £900 for a leasehold property.
What London Buyers and Sellers Actually Pay
Based on the latest 2026 data:
Buyers in London:
The average conveyancing cost for a London buyer is £3,074 (CompareMyMove, 2026). This is 76% above the UK national average of £1,624. For context:
- South London buying: average £1,500 to £2,500
- Central London buying (Zone 1 and 2): typically £2,500 to £4,500 given higher property values
- Leasehold flat: add £300 to £800 for lease review, management pack, and additional requisitions
A buyer purchasing a £600,000 leasehold flat in Zone 2 should budget approximately £3,000 to £4,000 in total conveyancing costs before stamp duty.
Sellers in London:
The average conveyancing cost for a London seller is £1,060 (CompareMyMove, 2026). Selling involves less legal work than buying — there are no searches to commission and no mortgage to set up — which is why sellers pay substantially less.
For leasehold sellers, the cost rises because you must obtain a leasehold seller’s pack from the freeholder or managing agent — this typically costs £300 to £800 and is recharged to you by your solicitor as a disbursement.
South London selling: average £1,600 to £2,400.
Buying and selling simultaneously:
Buyers and sellers in the same transaction often use the same solicitor to handle both sides. This does not produce a full saving on each bill, but most solicitors offer a combined instruction discount. The total average for buying and selling in 2026 is £2,434 (Reallymoving Conveyancing Costs Index Q1 2025) nationally, but in London the combined cost typically runs £3,500 to £5,500 depending on property values and leasehold complexity.
The London Premium: Why Conveyancing Costs More Here
London conveyancing costs more than the national average for three structural reasons.
Higher property values. Most conveyancers charge fees on a percentage-of-value or value-banded basis. A solicitor charging 0.1% of the purchase price on a £600,000 London flat bills £600 in legal fees before any add-ons. The same percentage on a £250,000 regional property produces £250. The value premium compounds through the bill.
High proportion of leasehold properties. Approximately 67% of all dwellings in London are flats. The vast majority of London flats are leasehold. Leasehold conveyancing involves significantly more legal work — reviewing the lease (which can be hundreds of pages), requesting and reviewing a management information pack from the freeholder, checking service charge accounts and outstanding liabilities, and flagging lease-specific issues including short leases, restrictive covenants, and unusual ground rent clauses.
Greater transaction complexity. London transactions are statistically more likely to involve chains, new-build special conditions, shared ownership, help to buy redemption, international buyers requiring additional due diligence, and properties with complex title history. Each additional complication adds billable legal time.

Freehold vs Leasehold: The Cost Difference
The Property Solvers 2026 survey of 100 conveyancing firms across England and Wales found:
- Average freehold purchase: £1,389.87 including VAT
- Average leasehold purchase: £1,743.48 including VAT
- Average freehold sale: £1,316.52 including VAT
- Average leasehold sale: £1,628.58 including VAT
These are national averages. London figures are consistently above these. The leasehold premium — approximately £300 to £400 over freehold — reflects the additional legal work involved in every leasehold transaction.
For buyers of leasehold properties in London, the additional due diligence around the lease is not just a cost — it is a protection. A solicitor who reviews the lease carefully and flags a doubling ground rent clause, an onerous service charge provision, or a short lease that would require extension before mortgage lending is available is protecting you from a purchase that could cost significantly more to exit than to enter.
What Drives the Variation in Conveyancing Quotes
Getting three to four conveyancing quotes for any London transaction is strongly recommended. The range between the cheapest and most expensive quotes for the same transaction can be £800 to £1,500 — a meaningful saving that requires one afternoon of comparison.
The main factors that drive variation between quotes:
Property value. Most conveyancers price on a tiered value basis. London properties are almost universally in the higher value tiers.
Freehold vs leasehold. Leasehold properties attract a surcharge on every quote — confirm this is included or excluded when comparing.
Whether you are buying, selling, or both. Combined instruction quotes are almost always better value than two separate instructions.
New build vs existing property. New build conveyancing involves additional work — developer contracts, title guarantee review, and build completion stages — and is typically priced higher than resale.
Mortgage vs cash purchase. Mortgage purchases involve additional correspondence with the lender and must comply with the lender’s specific legal requirements — cash purchases are simpler and typically cheaper.
Fixed fee vs hourly rate. Most residential conveyancers now offer fixed fees for standard transactions — this is preferable because it eliminates the risk of fee escalation if the transaction becomes complicated.

How to Keep Conveyancing Costs Under Control in London
Compare quotes from multiple firms. Use comparison platforms including CompareMyMove, Reallymoving, and the Law Society Find a Solicitor tool to get three to four quotes for your specific transaction type and property.
Check what is and is not included. Some quotes are inclusive of all disbursements; others quote legal fees only and list disbursements separately. Compare total cost to total cost — not legal fees to legal fees.
Use one firm for both sides if buying and selling. Combined instructions produce a discount and simplify communication during what is often the most stressful period of a property transaction.
Avoid low-cost online-only conveyancers for complex transactions. For a straightforward freehold purchase, an online conveyancer can save £300 to £600 without meaningful risk. For a London leasehold with a short lease, a complex chain, or an international buyer, a specialist London conveyancer with direct contact capability is worth the premium.
Start the process early. Delays in conveyancing generate additional work, additional correspondence, and sometimes additional fees. Instructing your solicitor at offer stage — before a surveyor is instructed — and providing all ID and financial documentation immediately reduces the risk of delay-related cost escalation.

Conclusion
The average conveyancing cost for a London buyer is £3,074 and for a London seller is £1,060 in 2026 — significantly above national averages of £1,624 and £1,023 respectively. Higher property values, the prevalence of leasehold properties, and greater transaction complexity all drive the London premium. For buyers, total budgeted conveyancing costs should be £2,500 to £4,500 for most Zone 1 and 2 leasehold transactions. For sellers, £1,000 to £2,000 is a realistic budget across most London transactions. Comparing three to four quotes, checking exactly what each includes, and instructing a conveyancer experienced in London leasehold transactions are the three most cost-effective actions available before any transaction begins.
Frequently Asked Questions
How can I reduce conveyancing fees for a London property transaction?
Compare at least three to four quotes using platforms like CompareMyMove or Reallymoving. Use one firm for both buying and selling if applicable. Check whether quotes include disbursements or list them separately. For straightforward freehold purchases, an online conveyancer can save £300 to £600. For leasehold transactions, prioritise a specialist London conveyancer with leasehold experience over the cheapest quote available.
Why is London conveyancing more expensive than the rest of the UK?
Three structural reasons: higher property values push fees up on value-banded pricing; a high proportion of leasehold properties in London require significantly more legal work; and London transactions are statistically more likely to involve chains, international buyers, new-build conditions, and complex title histories that all generate additional billable work.
How much do conveyancing fees cost for a seller in London?
The average conveyancing cost for a London seller is £1,060 in 2026. Sellers pay substantially less than buyers because they do not commission searches, register title, or arrange mortgage documentation. Leasehold sellers pay more — add £300 to £800 for the leasehold seller’s pack from the freeholder or managing agent.
