CQS Accreditation Explained: Does Your Solicitor Need It?

If you are selling a property in England or Wales, you may have come across the term "CQS accredited" when searching for a conveyancing solicitor. Some firms display it prominently on their websites. Some lenders insist on it. But what does it actually mean, and should it matter to you as a seller?

This guide explains what CQS accreditation is, who runs it, what firms must demonstrate to get it, and — most importantly for sellers — whether your solicitor needs it to handle your sale.

What is the Conveyancing Quality Scheme?

The Conveyancing Quality Scheme (CQS) is an accreditation programme run by the Law Society of England and Wales. It was launched in 2011 to provide a recognised quality standard for residential conveyancing practices. The scheme is voluntary — no solicitor firm is required to hold it — but it has become a de facto requirement for many firms that want to appear on mortgage lender panels.

CQS accreditation tells you that a firm has been independently assessed against a set of standards covering:

• Case management procedures — how the firm tracks and progresses conveyancing transactions
• Client care — how the firm communicates with clients and handles complaints
• Staff training and supervision — ongoing professional development for conveyancing staff
• Regulatory compliance — adherence to SRA rules,anti-money laundering obligations, and professional indemnity insurance requirements
• File management and record keeping — proper documentation of all transactions

The Law Society describes CQS as providing "a recognised quality standard for residential conveyancing practices" and a "kitemark" that mortgage lenders can rely on when deciding which firms to include on their panels. For a broader look at what your solicitor does during a sale, see our guide on what your solicitor actually does when you sell.

What firms must demonstrate to get CQS

Obtaining CQS accreditation is not a rubber-stamp exercise. The Law Society requires applicant firms to demonstrate compliance across several areas. Here is what the assessment covers:

The Law Society publishes a detailed CQS core practice management standards document that sets out the full requirements. Firms must submit evidence of compliance and may be subject to desk-based or on-site assessments.

The annual audit process

CQS accreditation is not a one-off achievement. The Law Society requires accredited firms to undergo an annual renewal process. This includes:

• Submitting updated self-assessment documentation confirming continued compliance with the CQS standards
• Providing evidence that staff training has been kept up to date
• Confirming that professional indemnity insurance and AML procedures remain in place
• Declaring any regulatory issues, complaints, or claims since the last renewal

The Law Society can also conduct random audits of accredited firms at any time. If a firm fails to meet the required standards during a renewal or audit, its CQS accreditation can be suspended or revoked. This acts as a strong incentive for firms to maintain their standards throughout the year, not just at renewal time.

From a seller's perspective, the annual audit means that a firm's CQS status is a reasonably current indicator of their compliance — though it is worth noting that audits assess systems and procedures, not the quality of individual case handling.

Why mortgage lenders require CQS

This is where CQS becomes directly relevant to property transactions. Most major UK mortgage lenders maintain an approved panel of solicitor firms authorised to act on their behalf in mortgage transactions. When a buyer takes out a mortgage, the lender needs a solicitor to handle the legal work on their behalf (checking the title, registering the mortgage charge, etc.). Lenders use CQS accreditation as a shortcut to assess whether a firm meets their minimum standards.

For sellers, this matters because the buyer's solicitor often needs to be on the lender's panel. If the buyer's solicitor does not hold CQS accreditation, the lender may refuse to instruct them, causing delays while the buyer finds a different solicitor or the lender arranges a separate panel firm.

For your own side of the transaction — acting purely as the seller — CQS accreditation is not strictly required. Your solicitor does not handle the buyer's mortgage work. However, if you are simultaneously buying another property with a mortgage, your solicitor will need to be on your lender's panel, and that usually means holding CQS accreditation.

Which lenders require CQS accreditation?

The table below shows the CQS requirements of major UK mortgage lenders. Note that lender panel requirements change periodically, so it is always worth confirming directly with the relevant lender.

Source: Based on publicly available lender panel requirements and the Law Society's CQS information page. Individual lender requirements may change. Always confirm with the specific lender before instructing.

As you can see, CQS has become a near-universal requirement among the biggest lenders. If you are also instructing a solicitor to handle a linked purchase with a mortgage, choosing a CQS-accredited firm avoids the risk of being told mid-transaction that your firm is not on the lender's panel.

How to check if a firm has CQS accreditation

Checking is straightforward and free. There are three ways to verify CQS status:

1. Law Society's Find a Solicitor tool. Visit the Law Society's online directory and search for the firm by name or location. The listing will show whether the firm holds CQS accreditation alongside other accreditations.
2. Ask the firm directly. CQS-accredited practices are usually happy to confirm their status. Many display the CQS logo on their website, letterhead, and marketing materials.
3. Check your mortgage lender's panel. If you are buying with a mortgage, your lender can confirm whether a specific firm is on their approved panel.

If you are comparing conveyancing quotes, checking CQS status should be part of your due diligence, especially if your transaction involves a mortgage on either side.

What happens if your solicitor does not have CQS

If your solicitor does not hold CQS accreditation, the consequences depend on the type of work they are doing:

If you are only selling (no linked mortgage work): There is no problem. Your solicitor does not need CQS accreditation to handle a straightforward sale. They only need to be properly regulated — either by the Solicitors Regulation Authority (SRA) or the Council for Licensed Conveyancers (CLC). For more on the differences between these regulators, see our guide on solicitor vs conveyancer.

If your solicitor is also handling a purchase with a mortgage: This is where it can become a problem. If your lender requires CQS accreditation and your firm does not have it, the lender will not allow that firm to act on their behalf. You would then face one of two options:

• Instruct a separate panel firm to handle the lender's work. This means paying two sets of solicitor fees and coordinating between two firms — adding cost and complexity.
• Switch solicitors entirely to a CQS-accredited firm. This can cause significant delays if you are already mid-transaction, as the new firm needs to take over the file, carry out fresh AML checks, and get up to speed on your case.

The simplest way to avoid this problem is to check CQS status and lender panel membership before you instruct. It takes two minutes and can save weeks of disruption later.

CQS vs CLC regulation: what is the difference?

This is a common source of confusion. CQS and CLC regulation are different things entirely, but they serve overlapping purposes in the eyes of mortgage lenders.

The key point for sellers is that both CQS-accredited solicitors and CLC-regulated conveyancers are competent to handle residential property transactions. The CLC requires its regulated firms to meet their own set of standards for client care, training, and compliance — so a CLC-regulated conveyancer is not "less regulated" than a CQS-accredited solicitor. They are simply regulated under a different framework. For a detailed comparison, see our guide on solicitor vs conveyancer.

Does CQS guarantee quality?

This is an important question, and the honest answer is: not exactly.

CQS accreditation confirms that a firm has systems and procedures in place that meet the Law Society's standards. It means the firm has invested in training, has proper case management processes, and has passed an assessment. That is a meaningful baseline, and it is better than no independent quality check at all.

However, CQS does not assess:

• How quickly individual solicitors respond to emails or phone calls
• The caseload each solicitor is carrying (a common cause of delays)
• Whether the firm provides proactive updates or waits for you to chase
• The quality of advice given on complex issues specific to your property
• Client satisfaction rates or outcomes

Think of CQS as a minimum quality threshold rather than a guarantee of excellent service. A CQS-accredited firm with 200 active cases and overstretched staff may deliver a worse experience than a smaller, non-CQS firm with a manageable workload and a strong reputation.

When choosing a solicitor, CQS status should be one factor among several. Also consider the firm's online reviews, their communication approach, their quoted fees, and whether they offer a no sale no fee guarantee. Our guide on how to compare conveyancing quotes covers what else to look for beyond accreditation.

Choosing a solicitor: where CQS fits in

For sellers, the decision about CQS comes down to your specific circumstances. Here is a practical framework:

CQS is important if:

• You are selling and buying simultaneously, and your purchase involves a mortgage
• You want the reassurance that your firm has been independently assessed against a recognised standard
• Your buyer's lender is asking questions about your solicitor's credentials (rare, but it happens in some situations)

CQS is less important if:

• You are selling only, with no linked purchase
• You are using a CLC-regulated conveyancer (who will have their own regulatory standards)
• You have a strong personal recommendation for a non-CQS firm with an excellent track record

Regardless of CQS status, always verify that your solicitor or conveyancer is properly regulated. You can check the SRA register for solicitors or the CLC register for licensed conveyancers. This is a non-negotiable check that applies to every firm, CQS or not. For a full rundown on how to find and instruct a solicitor for selling, see our dedicated guide.

How Pine helps you get sale-ready

Whichever solicitor you choose — CQS-accredited or not — the biggest factor in a smooth sale is preparation. Most conveyancing delays happen because sellers have not completed their property information forms, gathered certificates, or thought about potential title issues before a buyer comes along.

Pine helps you do this groundwork before you instruct a solicitor. You can complete your TA6 and TA10 forms with plain-English guidance, gather supporting documents, and order property searches at near-trade prices. When you are ready to instruct, you hand your solicitor a ready-made pack — saving weeks of back-and-forth. For a detailed look at what this process involves and what it costs, see our conveyancing costs breakdown.
