Remortgaging — the process of switching from one mortgage to another, typically to secure a better interest rate, release equity, or consolidate debt — is the highest-volume sector of residential conveyancing. UK Finance data shows that approximately 700,000 remortgage transactions are completed in England and Wales each year in normal market conditions, with volumes rising significantly when interest rates change and fixed-rate deals expire. For conveyancing firms that run remortgage panels, this is bread-and-butter work; run efficiently, it generates strong margin; run poorly, it generates complaints, professional indemnity claims, and lender panel exclusions.

This guide covers the remortgage conveyancing process from instruction to completion, the critical differences between remortgages and purchase transactions, the lender panel management obligations that govern practice, and the operational considerations for firms running high-volume remortgage departments.

What Is Remortgage Conveyancing?

In a remortgage, the borrower does not change the property they own — they change the mortgage secured on it. From a conveyancing perspective, the key legal steps are:

Redeeming (paying off) the existing mortgage and removing the existing charge from the title register
Registering the new mortgage as a new charge on the title register

Because there is no buyer and no seller — merely a borrower and a new lender — the transaction is significantly simpler than a purchase. There is no transfer of title, no exchange of contracts, and no chain. The solicitor almost always acts for both the borrower and the new lender simultaneously, under the terms of the UK Finance Mortgage Lenders’ Handbook.

When Is Conveyancing Not Required for a Remortgage?

Where a borrower is switching to a new product with the same lender (a product transfer), no conveyancing is required because the charge on the register does not change. Product transfers have become increasingly common as lenders compete to retain customers approaching the end of their fixed-rate period. Where a borrower is switching to a new lender — even if the amount borrowed stays the same — conveyancing is required.

Stage One: Instruction and Onboarding

AML and Identity Verification

Remortgage solicitors must comply fully with the Money Laundering Regulations 2017 and the SRA’s AML Practice Note. This means verifying the identity and address of all borrowers, establishing the purpose of the remortgage, and — where equity is being released — understanding the source of any additional funds if the new mortgage is larger than the existing one.

The AML risk profile for a remortgage is generally lower than for a purchase because there is no third party paying the purchase price, but it is not zero. Mortgage fraud — where a borrower overstates their equity or misrepresents the property’s value — is a risk the solicitor’s checks help to mitigate.

Digital onboarding (using an IDSP for identity verification) is particularly well-suited to remortgages, where the client may already be familiar with digital processes and there is no time pressure from an exchange date.

The Mortgage Offer

The starting point for remortgage conveyancing is the mortgage offer received from the new lender. The solicitor should check:

That the names and address on the offer match the title register and the client’s identity documents
That the mortgage amount and term match what the client expects
Any conditions attached to the offer (minimum lease term, works conditions, search conditions)
The expiry date of the offer

Where the mortgage offer has conditions — for example, a requirement that there be a minimum of 70 years remaining on the lease, or that specific damp repairs be carried out — the solicitor must ensure these conditions are discharged before completion.

Stage Two: Title Investigation

Official Copies of the Register

The solicitor obtains official copies of the borrower’s title register and title plan from HMLR. For remortgages, the title investigation is narrower than for a purchase because the lender is taking a charge on an existing registered title — there is no “who owns this?” question. The investigation focuses on:

Confirming the borrower’s title: The borrower must be the registered proprietor (or one of them). Where the title is held jointly (for example, by two spouses), both must be parties to the new mortgage.

Existing charges: The official copies will reveal all existing registered charges. The solicitor must ensure that the new lender’s charge will be in the priority position required by the mortgage offer — typically first legal charge. If there is a second charge (for example, a home equity loan), the lender’s handbook instructions must be followed regarding whether the second charge can remain.

Restrictions on the register: Any restriction in the proprietorship register that requires consent to a dealing must be complied with. A common restriction requires the consent of a management company or a charging party. The solicitor must obtain that consent before completion.

Lease terms (for leasehold remortgages): The solicitor must check that the lease complies with the lender’s requirements under the Mortgage Lenders’ Handbook — minimum unexpired term, acceptable ground rent provisions, adequate insurance, and no onerous terms.

Searches

Search requirements for remortgages vary by lender. The UK Finance Mortgage Lenders’ Handbook Part 2 (the lender-specific section) specifies for each lender whether:

Full searches are required
Search insurance is acceptable in lieu of searches
The solicitor’s own search insurance is acceptable
No searches are required (very rare)

Most lenders accept search insurance for remortgages, which means that instead of ordering a full local authority, drainage, and environmental search (which takes time and costs the client money), the solicitor obtains a search insurance policy from an approved insurer. This is faster and cheaper, and is appropriate because the borrower has been living in the property and would typically know about any significant local authority issues.

Where the lender requires full searches, the same searches as for a purchase are ordered.

Stage Three: The Mortgage Deed

Executing the Mortgage Deed

The mortgage deed (also known as the legal charge) is the document by which the borrower charges their property to the lender as security for the loan. It must be executed as a deed — which for an individual requires signature in the presence of an independent witness.

For remortgages, the mortgage deed is almost always provided by the lender in a standardised form that incorporates the lender’s standard mortgage conditions by reference. The solicitor should send the deed to the borrower with a clear covering letter explaining:

What the deed is and what it means
That they are granting the lender security over their home
The consequences of defaulting on the mortgage
Any significant conditions or clauses the borrower should note

The solicitor must not simply send the deed without explanation and invite the client to sign it — this is a failure to adequately advise and is a common source of complaints.

Digital Mortgage Deeds

Since HMLR launched its Digital Mortgage Service, an increasing number of remortgages are completed using a digital mortgage deed — executed electronically using a qualified electronic signature, without a paper deed. The digital mortgage deed is transmitted directly from the lender’s platform to HMLR via the Business Gateway, bypassing the traditional paper process.

Not all lenders have adopted digital mortgage deeds; many still issue paper deeds. Solicitors should check the lender’s instructions on how the mortgage deed is to be executed and returned.

Stage Four: The Redemption Statement

Before completion, the solicitor must obtain a mortgage redemption statement from the existing lender — the precise amount required to pay off the existing mortgage on the proposed completion date. This amount will include:

The outstanding capital balance
Accrued interest to the completion date
Any early repayment charge (ERC)
Any administration fee charged by the lender for providing the redemption statement

Early repayment charges can be significant — for a borrower on a fixed-rate mortgage who is remortgaging before the end of the fixed-rate term, ERCs of 1% to 5% of the outstanding balance are common. The solicitor should confirm with the client that they are aware of the ERC and have factored it into the financial decision to remortgage. If the ERC will be deducted from the net proceeds, the completion statement must reflect this.

Stage Five: The Completion Statement

The completion statement for a remortgage sets out:

The amount required from the new lender
The existing mortgage redemption amount
The solicitor’s fees
Disbursements (search insurance, HMLR fees, CHAPS fees, AML check fees)
Any other sums payable (for example, outstanding ground rent or service charge arrears if the property is leasehold)
The net amount payable to the borrower (or from the borrower, if they are topping up the mortgage)

The completion statement must be approved by the borrower before completion. Where the borrower is releasing equity and will receive net funds, clear advice about how those funds will be remitted and the tax implications (if any) of the equity release should be provided.

Stage Six: Completion and Registration

Completion

On completion day, the new lender releases the mortgage advance to the solicitor’s client account. The solicitor then:

Pays the redemption amount to the existing lender by CHAPS
Remits any net proceeds to the borrower (if equity is being released)
Pays their own fees and disbursements from the funds

Timing is important: the CHAPS payment to the existing lender must arrive in time for the existing lender to effect the discharge on the same day, or the existing charge will remain on the register overnight. Most major lenders effect the discharge electronically (via e-DS1) the same day, but the solicitor should confirm this.

Post-Completion: Registration

The solicitor must register the new charge at HMLR within the OS1 priority period (30 business days from the official search). The application consists of:

The DS1 or e-DS1 (discharge of the existing mortgage)
The new mortgage deed or digital mortgage application

Where the existing lender uses e-DS1, the discharge is effected automatically by the lender notifying HMLR directly, and the solicitor’s application only needs to include the new charge application. Where the existing lender uses a paper DS1, the solicitor must receive the signed DS1 from the existing lender (usually within a few weeks of redemption) and submit it with the charge registration application.

Post-completion delays are most common when the DS1 is delayed by the outgoing lender. Solicitors should chase the DS1 proactively if it has not been received within four weeks of redemption.

Running a High-Volume Remortgage Department

Lender Panel Management

To act on remortgages for mortgage lender clients, a firm must be a member of the relevant lender’s conveyancing panel. Most lenders operate their own panels (or use Lender Exchange, a shared panel management platform operated by LMS). Panel membership involves:

Periodic due diligence checks on the firm’s SRA compliance, professional indemnity insurance, and cyber security
Adherence to the lender’s specific panel terms and the relevant section of the Mortgage Lenders’ Handbook
Reporting certain matters (title defects, suspected fraud, conflicts of interest) to the lender

Lender panel exclusions — being removed from a lender’s panel — are serious commercial events. They typically result from reporting failures, fraud involvement (even unwitting), or significant client complaints.

Process Efficiency

Remortgage conveyancing is inherently suitable for process-driven, high-volume delivery. The steps are predictable, the documents are standardised, and the main variables are lender-specific requirements. Firms that run successful remortgage departments invest in:

Automated document generation (mortgage reports, completion statements)
Digital client onboarding
Integration with lender platforms for mortgage offer receipt and DS1/e-DS1 management
Systematic diary management for offer expiry dates, priority period deadlines, and DS1 receipt

Obiter assists remortgage teams by processing incoming mortgage offers, automatically populating the matter record, drafting the report to borrower, and tracking every key deadline — enabling one fee earner to handle significantly more matters without the risk of something falling through the cracks.
