Selling a Leasehold Flat: Process and Extra Costs

Leasehold flats make up the vast majority of flat sales in England and Wales. According to the Ministry of Housing, Communities & Local Government, there are approximately 4.98 million leasehold dwellings in England alone, and most of these are flats. If you are selling one, you will encounter a process that is broadly similar to selling a freehold house but with several additional steps that can add weeks to your timeline and hundreds of pounds to your costs.

This guide covers the entire process of selling a leasehold flat from a seller's perspective. It explains what makes leasehold sales different, what extra documents you need, how much you should expect to pay, and how to avoid the delays that cause leasehold transactions to drag on far longer than they should.

What makes selling a leasehold flat different?

When you sell a freehold property, you are selling the land and the building outright. When you sell a leasehold flat, you are selling a time-limited interest in the property — the right to live in it for the remaining term of your lease, subject to the terms set out in that lease. The freeholder retains ownership of the building and the land.

This distinction has practical consequences for the sale process:

• Additional paperwork. You need the TA7 Leasehold Information Form in addition to the standard TA6 and TA10 forms. The TA7 covers the lease terms, ground rent, service charges, building insurance, and the management structure.
• Management pack required. You must order a leasehold management pack from your freeholder or managing agent. This is the single biggest source of delay in most leasehold sales.
• Lease length scrutiny. The buyer's mortgage lender will check the remaining term of your lease. If it is below 80 years, you may face difficulties selling at full market value.
• Ground rent and service charge checks. The buyer's solicitor and lender will examine your ground rent provisions (especially any escalation clauses) and your service charge history.
• Third-party involvement. Your freeholder and managing agent play an active role in the transaction, and their responsiveness directly affects how quickly your sale progresses.

The leasehold sale process: step by step

Here is what the process looks like from the point you decide to sell through to completion. Steps marked with an asterisk (*) are specific to leasehold sales.

1. Instruct a solicitor or conveyancer. Choose a solicitor or conveyancer with leasehold experience. Leasehold transactions involve additional enquiries and documents that not all firms handle routinely.
2. Order the leasehold management pack.* Contact your managing agent or freeholder and request the LPE1 pack. Pay the fee promptly — the agent will not start preparing the pack until payment is received. This typically takes two to four weeks to arrive.
3. Obtain your EPC. If your Energy Performance Certificate has expired or you do not have one, arrange a new one before you market the property.
4. Complete the TA6, TA7, and TA10 forms.* Your solicitor will send you the forms to complete. The TA7 draws heavily on the management pack and your lease document. See our detailed guide on the TA7 Leasehold Information Form.
5. Market the property and accept an offer. List your flat through your estate agent. Once you accept an offer, provide your buyer's details to your solicitor.
6. Your solicitor sends the draft contract pack. This includes the contract, title documents, TA6, TA7, TA10, the management pack (LPE1), and any supporting documents. The faster this pack is sent, the faster the buyer's solicitor can begin their work.
7. The buyer's solicitor raises enquiries. Leasehold sales generate more enquiries than freehold ones. Expect questions about ground rent review mechanisms, service charge reasonableness, planned major works, building safety, and the lease length.
8. Enquiries are resolved and the mortgage offer is issued. Once the buyer's solicitor is satisfied and the mortgage lender has approved the property, the parties can move towards exchange.
9. Exchange of contracts. Both parties are legally committed. The buyer pays the deposit (typically 10%).
10. Completion. Funds transfer, service charges and ground rent are apportioned, the notice of assignment is served on the freeholder, and you hand over the keys.

How long does a leasehold sale take?

Leasehold sales consistently take longer than freehold ones. Based on industry data and HM Land Registry processing times, here is how the two compare:

The single biggest factor in this difference is the leasehold management pack. If you order it before listing and have it ready when you accept an offer, you can eliminate most of the additional delay. For a detailed breakdown of the overall conveyancing timeline, see our guide on how long conveyancing takes.

Extra costs of selling a leasehold flat

Leasehold sellers face several costs that freehold sellers do not. Here is what you should budget for on top of your standard conveyancing costs:

In total, leasehold-specific charges can add £300 to £900 to the cost of selling, on top of your standard solicitor fees, estate agent commission, and other disbursements. For a full picture of what a leasehold management pack costs and why prices vary, see our dedicated guide on leasehold management pack costs.

The management pack: your biggest bottleneck

The leasehold management pack is the most important document in a leasehold sale and the most common cause of delay. It is prepared by your managing agent or freeholder and is based on the LPE1 (Leasehold Property Enquiries) form published by the Law Society. The pack typically includes:

• The completed LPE1 form with answers about service charges, ground rent, insurance, reserve funds, major works, and disputes
• The last three years' service charge accounts and the current year's budget
• The buildings insurance schedule showing the insurer, policy number, sum insured, and whether terrorism cover is included
• Details of any Section 20 notices for planned major works
• Confirmation of any outstanding arrears on the seller's account
• Fire risk assessments, EWS1 forms, and other compliance certificates where applicable

The standard turnaround for a management pack is two to four weeks from the date you order and pay. If you wait until after accepting an offer to order it, this wait sits directly on the critical path of your conveyancing timeline — nothing else can progress until the pack arrives and your solicitor can complete the TA7.

The most effective step any leasehold seller can take is to order the management pack before listing the property. If the pack is sitting ready when you accept an offer, your solicitor can send the draft contract pack to the buyer's solicitor within days rather than weeks. This is exactly the approach Pine is designed to support — getting your legal documents prepared upfront so the transaction can move quickly from the moment a buyer is found.

Lease length: the issue that can make or break your sale

The remaining term of your lease is one of the most significant factors in any leasehold sale. It affects your property's market value, the buyer's ability to secure a mortgage, and how quickly you can sell. LEASE (the Leasehold Advisory Service) advises leaseholders to think carefully about their lease length well before putting their property on the market.

How lease length affects mortgage availability

Most UK mortgage lenders follow guidance set out in the UK Finance Lenders' Handbook, which stipulates minimum remaining lease terms. While each lender sets its own criteria, the general position is:

• Over 80 years remaining: Most lenders will lend without lease-related conditions.
• 70 to 80 years: Many mainstream lenders decline or impose restrictive conditions. Your buyer pool shrinks considerably.
• Under 70 years: Very few lenders will lend. The property is effectively restricted to cash buyers or specialist lenders, reducing demand and price significantly.

The 80-year cliff edge

There is a critical threshold at 80 years. Under the Leasehold Reform, Housing and Urban Development Act 1993, qualifying leaseholders have the right to extend their lease by 90 years at a peppercorn ground rent. The premium (the price you pay the freeholder for the extension) is calculated based on the remaining term, the ground rent, and the property's value.

Once the lease drops below 80 years, the calculation includes marriage value — the increase in the property's value that results from the extension. This marriage value is split 50/50 between the leaseholder and the freeholder, which can add tens of thousands of pounds to the cost of extending. For a flat worth £300,000 with 75 years remaining, the premium might be £15,000 to £25,000. With 90 years remaining, the same extension might cost only £5,000 to £8,000.

The Leasehold and Freehold Reform Act 2024 includes provisions to abolish marriage value, which would make lease extensions significantly cheaper for those with short leases. However, as of February 2026, this provision has not yet come into force. Sellers with short leases should check the latest position with LEASE or their solicitor before making decisions about extending.

Ground rent: what buyers and lenders look for

Ground rent is one of the most scrutinised aspects of any leasehold sale. The buyer's mortgage lender will check the ground rent provisions in your lease before approving the loan, and problematic ground rent clauses can derail a sale.

Key points to be aware of as a seller:

• Fixed ground rent that stays the same for the lease term is the simplest arrangement and causes no issues with lenders.
• RPI-linked ground rent that increases in line with the Retail Prices Index at set intervals is generally acceptable to lenders, provided the increases are capped at a reasonable level.
• Doubling clauses are the most problematic. If your ground rent doubles at fixed intervals (for example, every 10 or 25 years), many lenders will refuse to lend on the property. The UK Finance Lenders' Handbook generally considers ground rent onerous if it exceeds 0.1% of the property's value or if the review mechanism could take it above that level within the first 20 years.
• Peppercorn ground rent (effectively zero) is common in share of freehold arrangements and causes no issues.

The Leasehold Reform (Ground Rent) Act 2022 capped ground rent at a peppercorn for most new long residential leases granted on or after 30 June 2022. If your lease was granted before that date, your existing ground rent terms continue unchanged. You must disclose the current ground rent, the review mechanism, and any escalation clauses clearly on the TA7 form.

Service charges and building insurance

The buyer's solicitor will examine your service charge history closely. They want to know how much the charges are, what they cover, whether there are any arrears on your account, and whether any major works are planned or in progress. All of this information comes from the management pack.

Common issues that generate additional enquiries include:

• Significant increases in service charges over the last three years, which the buyer may want explained
• Planned Section 20 major works (such as roof repairs, lift replacement, or cladding remediation) where costs have not yet been finalised
• Low reserve fund balances that suggest a large supplementary charge may be coming
• Missing or outdated buildings insuranceschedules — the buyer's lender requires confirmation that the building is adequately insured at full rebuild value

Being transparent about these matters upfront, rather than waiting for the buyer's solicitor to ask, saves time and builds trust. Make sure the management pack is comprehensive and your TA7 answers are consistent with it.

Building safety and the EWS1 form

Since the Grenfell Tower fire in 2017, building safety has become a major focus in leasehold flat sales, particularly for buildings over 11 metres (approximately four storeys) tall. The Building Safety Act 2022 introduced new obligations for building owners, and mortgage lenders now require evidence of building safety compliance before approving loans on affected buildings.

As a seller, you should be aware of:

• EWS1 (External Wall System) forms. These are fire safety assessments for the external walls of the building. If your building is over 18 metres tall or has cladding, the buyer's lender may require an EWS1 form with a satisfactory rating. Obtaining an EWS1 is the responsibility of the building owner (freeholder), not individual leaseholders, but delays in obtaining one can stall your sale.
• Building safety certificates. The managing agent should be able to provide fire risk assessments and other safety documentation through the management pack. If these are missing or outdated, the buyer's lender may refuse to proceed.
• Remediation costs. If the building requires cladding or other safety remediation work, the question of who pays — and how much leaseholders will be asked to contribute — is critical. The Building Safety Act 2022 introduced protections for leaseholders in qualifying buildings, limiting their liability for historical safety defects.

How to speed up a leasehold flat sale

The delays in leasehold sales are well known, but most of them are avoidable if you prepare properly. Here are the most effective steps:

1. Order the management pack before you list. This is the single most impactful thing you can do. If the pack is ready when you accept an offer, you eliminate the two-to-four-week wait that is the main cause of leasehold delays.
2. Complete the TA7 form early. Once you have the management pack and your lease document, fill in the TA7 straight away. Do not wait for your solicitor to chase you.
3. Check your lease length. If it is approaching 80 years, consider starting the lease extension process before you sell. While this adds time upfront, it can make your property significantly easier and faster to sell.
4. Clear any arrears. Check with your managing agent that your ground rent and service charge accounts are up to date. Arrears will be flagged by the buyer's solicitor and can cause delays or even put the sale at risk.
5. Provide comprehensive information. The more thorough your TA7 answers and the more supporting documents you provide upfront, the fewer additional enquiries the buyer's solicitor will raise. Each round of enquiries can add one to two weeks to the timeline.
6. Choose a solicitor with leasehold experience. Not all conveyancers handle leasehold sales regularly. A solicitor who understands the specific requirements will manage the process more efficiently. See our guide on how long conveyancing takes for more on keeping the timeline tight.

Share of freehold: a special case

If you own a share of freehold flat, you hold both a lease and a share in the freehold company that owns the building. This is increasingly common in smaller blocks (typically two to six flats) where the leaseholders have collectively purchased the freehold.

Selling a share of freehold flat is legally a leasehold sale — the buyer is purchasing your lease — so you still need the TA7 form and should provide a management pack or equivalent information. However, there are some differences:

• The ground rent is usually a peppercorn (zero), which eliminates one common source of buyer concern.
• The management pack may be simpler and cheaper to produce because the freehold company (which you partly own) prepares it rather than a professional managing agent.
• As a director of the freehold company, you may need to transfer your share in the company to the buyer, which requires a separate stock transfer form and possibly Companies House filings.
• Extending the lease is simpler and cheaper because the freehold company can grant the extension informally, without the statutory process.

The Leasehold and Freehold Reform Act 2024: what sellers need to know

The Leasehold and Freehold Reform Act 2024 received Royal Assent on 24 May 2024 and represents the most significant change to leasehold law in decades. While many of its provisions are not yet in force (awaiting secondary legislation), sellers should be aware of the key changes on the horizon:

• Abolition of marriage value. When brought into force, this will make lease extensions cheaper for leaseholders with fewer than 80 years remaining. The 50/50 split of marriage value between leaseholder and freeholder will be removed.
• Potential fee caps. The Act gives the government the power to cap the fees freeholders and managing agents charge during property sales, which could reduce the cost of the management pack, deed of covenant, and notice of assignment.
• Extended lease terms. The Act proposes that leaseholders will be able to extend their lease to 990 years (up from the current 90-year statutory extension for flats), making the extended lease more attractive to buyers.
• Transparency requirements. New requirements for freeholders and managing agents to provide information to leaseholders could make the management pack process faster and more standardised.

As of February 2026, sellers should not assume these changes are in effect. Check with your solicitor or with LEASE for the latest position on which provisions have been commenced.

Seller's checklist for a leasehold flat sale

Use this checklist to make sure you have covered all the leasehold-specific steps alongside the standard selling process:

1. Instruct a solicitor with leasehold conveyancing experience
2. Locate your lease document (or order a copy from HM Land Registry for £7)
