Conveyancing Timeline: How Long Does It Take and Why?

You've had your offer accepted. You're excited. Then someone mentions that completion could be 12 to 16 weeks away — and you wonder what on earth takes so long.

Conveyancing is the legal process of transferring ownership of a property from seller to buyer. In England and Wales, it is notoriously slow by international standards. The average transaction takes 10–14 weeks, but chains, leasehold complications and mortgage delays regularly push that to 20 weeks or more. Understanding each stage helps you manage expectations, spot when things are going wrong, and take steps to keep your purchase on track.

The Overall Timeline at a Glance

Most transactions follow the same sequence, even if the duration of each stage varies significantly:

1. Offer accepted → instruct solicitors (Day 1)
2. Solicitor due diligence and searches (Weeks 1–6)
3. Mortgage offer issued (Weeks 3–8)
4. Enquiries raised and resolved (Weeks 4–10)
5. Exchange of contracts (Weeks 8–16)
6. Completion (typically 1–4 weeks after exchange)

For a chain-free, freehold purchase with a straightforward mortgage, 8–10 weeks is achievable. For leasehold flats, large chains or complex titles, budget for 16–20 weeks.

Stage-by-Stage Breakdown

Stage 1: Instructing Your Solicitor (Days 1–7)

Once your offer is accepted, instruct a solicitor or licensed conveyancer immediately. Do not wait for the memorandum of sale (the estate agent's written confirmation) — call on the day your offer is accepted and get the anti-money-laundering ID checks started.

The seller's solicitor will send a draft contract pack to your solicitor. This pack includes:

• The draft contract
• Official copies of the title register and title plan from HM Land Registry
• Property information forms (TA6 and TA10)
• Leasehold information (TA7) if applicable

Common delay here: The seller hasn't yet instructed their own solicitor, or the title pack takes weeks to compile because the seller can't locate old planning consents, building regulations certificates or guarantees.

Stage 2: Searches (Weeks 1–5)

Your solicitor will order a bundle of searches on your behalf. These are enquiries sent to third-party authorities to reveal matters that would not appear on the title register.

Local authority search — checks planning history, enforcement notices, road adoption, tree preservation orders, and whether the property is in a conservation area or flood risk zone. Currently takes 2–6 weeks depending on the local authority. Some councils (notably in London) are notoriously slow; others return results within a few days.

Drainage and water search — confirms the property is connected to the public sewer and water main, and whether a public sewer runs through the property (which would restrict building). Typically 2–5 days (automated from Thames Water, Severn Trent, etc.).

Environmental search — checks for contaminated land, landfill sites, flooding, radon gas risk, and subsidence. Typically 1–3 days (automated database).

Chancel repair search — checks whether the property falls within a historic parish boundary that could give the local church a claim against the owner for repair costs. Most solicitors now recommend indemnity insurance (£20–£40 one-off) rather than the formal search.

Optional searches your solicitor may recommend include a flood risk search, a coal mining search (if in a former mining area), a tin or clay mining search (Cornwall/Devon), or a HS2 infrastructure search.

Common delay here: Local authority searches. If your local council is running behind, nothing can be done to speed it up. Some solicitors will order personal searches (carried out by a private firm at the council's offices) which are faster but not accepted by all mortgage lenders.

Stage 3: Mortgage Offer (Weeks 3–8)

If you are using a mortgage, your lender will instruct a surveyor to carry out a mortgage valuation. This is the lender's own assessment — not a survey for your benefit. Once the valuation is satisfactory, the lender issues a formal mortgage offer. Your solicitor receives a copy and reviews the conditions.

Common delays here:

• The valuation comes back below the purchase price (a down-valuation), requiring renegotiation or a new lender
• The lender requests additional documentation (payslips, bank statements, evidence of deposit source)
• Interest rate changes prompt you to switch products or lenders mid-process, restarting the clock

Stage 4: Enquiries (Weeks 4–10)

Once your solicitor has the contract pack, searches and mortgage offer, they will raise enquiries — written questions to the seller's solicitor about anything unclear or potentially problematic. Common enquiries cover:

• Planning consent and building regulations completion certificates for extensions or alterations
• Evidence of guarantees (damp-proof course, timber treatment, double glazing FENSA certificates)
• Boundaries and disputes with neighbours
• Shared rights of way or maintenance obligations
• Ground rent review clauses (leasehold)
• Service charge accounts and forthcoming major works (leasehold)

The seller must answer every enquiry before contracts can be exchanged. If the seller is slow to respond, or if their answers prompt further enquiries, this stage can drag on for weeks.

Common delays here: Sellers who ignore their solicitor's requests; missing planning consents that require retrospective regularisation or indemnity insurance; leasehold sellers waiting for the freeholder's management information pack (which can take 4–6 weeks and cost £300–£600 to obtain).

Stage 5: Exchange of Contracts (Weeks 8–16)

Exchange is the legal point of no return. Both parties sign identical contracts, your solicitor releases your deposit (usually 10% of the purchase price) to the seller's solicitor, and a completion date is agreed. From exchange, neither party can pull out without serious financial consequence.

Before exchange, your solicitor will:

• Report to you on the title and enquiries
• Confirm the mortgage offer conditions are satisfied
• Obtain your signed contract and transfer deed
• Arrange buildings insurance to start on exchange (critical — you are legally committed)

Common delays here: Any party in a chain who isn't ready. Every link must exchange simultaneously, so one slow buyer or seller can hold up an entire chain of four or five transactions.

Stage 6: Completion (1–4 Weeks After Exchange)

Completion is when ownership legally transfers. Your solicitor sends the balance of the purchase price to the seller's solicitor by electronic bank transfer. Once received, the estate agent releases the keys.

Your solicitor will then pay Stamp Duty Land Tax (SDLT) to HMRC and register the new title at HM Land Registry (currently running 2–6 weeks for registered properties, longer for first registrations).

Summary Table: Stages, Timescales and Delay Causes

Common Reasons Conveyancing Takes Longer Than Expected

Chain collapses — If any party in a chain withdraws (due to a failed survey, cold feet, or mortgage problems), the entire chain may collapse. Around 30% of sales agreed in England and Wales fall through before completion.

Leasehold complications — Leasehold properties require additional documents: the management information pack (including service charge accounts, buildings insurance, ground rent demands and details of any major works planned or in progress). Freeholders are not legally required to respond quickly, and many solicitors note management companies taking 4–8 weeks to respond.

Slow sellers or solicitors — Some sellers leave enquiry responses for weeks. Some solicitors are simply under-resourced or unresponsive. A proactive solicitor chasing regularly makes a measurable difference.

Mortgage valuation issues — A down-valuation requires you to either renegotiate the price, increase your deposit, or find a new lender — all of which take time.

Title defects — Missing planning consents, unregistered rights of way, or disputed boundaries can take weeks to resolve through indemnity insurance or corrective applications to HM Land Registry.

How to Speed Up Your Conveyancing

Instruct your solicitor before offer acceptance. Get quotes, check reviews, and have your solicitor chosen before you start making offers. The moment your offer is accepted, instruct immediately.

Get a mortgage in principle before you offer. A decision in principle (DIP) means your lender has already done basic credit and affordability checks. Once your full application goes in, the process is faster.

Respond quickly to your solicitor. Every time your solicitor sends you documents to sign or questions to answer, treat it as urgent. Delays on your end slow everything down.

Use a proactive solicitor. The difference between a conveyancer who chases daily and one who waits for calls is often 4–6 weeks. Ask specifically: "How often will you chase other parties? Do you have a dedicated case handler?" Check reviews on Google or the Law Society's Find a Solicitor tool.

Agree a completion date at offer stage. If you and the seller agree a target completion date when the offer is made, all parties in the chain have a target to work towards.

Consider a no-sale, no-fee conveyancer. These firms charge nothing if the transaction falls through, which removes the financial disincentive to withdraw early and can make chains more stable.

For leasehold purchases: Ask the seller to order the management information pack the moment the sale is agreed. This pack is the single biggest cause of leasehold delays.

Scotland and Northern Ireland: Different Rules

This guide covers England and Wales. Scotland uses a distinct legal system where offers are made through solicitors and acceptance creates a binding contract immediately (the 'missives' process). Transactions in Scotland are generally faster — often 4–8 weeks. Northern Ireland uses a similar system to England and Wales but with some procedural differences.

What to Do If Your Transaction Is Stalling

1. Ask your solicitor for a written status update — Where exactly are we? What is outstanding? Who is causing the delay?
2. Contact the estate agent — They have a financial incentive to complete and can often chase the other side effectively.
3. Set a deadline — If you are not in a chain, you can set a fixed exchange deadline and make clear you will withdraw if it isn't met. This concentrates minds.
4. Escalate within the firm — If your solicitor is the problem, ask to speak to a partner or supervisor.

Key Takeaways

• The average conveyancing transaction takes 10–14 weeks; chains and leasehold add 4–8 weeks
• Searches, enquiries, and mortgage valuation run in parallel — the slowest determines the overall pace
• Instructing a solicitor immediately and responding quickly to requests are the two things within your control
• Leasehold purchases require the management information pack — push for this to be ordered on day one
• A proactive, responsive solicitor is worth paying slightly more for
