Remortgage vs Product Transfer — Which Is Better in 2026?

Two Paths at Mortgage Renewal

Every two, three, or five years, most UK mortgage holders face the same decision: do you stay with your current lender on a new deal (product transfer) or take your business to a new lender (remortgage)?

The right answer depends on rates, your changed financial circumstances, and the costs involved. Use our [remortgage savings calculator](/remortgage-calculator) to model the financial difference between your best available options.

What Is a Product Transfer?

A product transfer (sometimes called a rate switch or internal remortgage) means you agree a new mortgage rate with your **existing lender** while keeping all other loan terms (balance, term, remaining conditions) unchanged.

The process is:

1. You approach your lender (directly or through a broker) to see their current product transfer rates

2. You select a deal — typically a two, three, or five-year fix

3. The new rate is applied from the start date with minimal paperwork

4. No solicitor, no new valuation, no new affordability assessment in most cases

Product transfers can often be arranged entirely online in under an hour.

What Is a Remortgage?

A remortgage means moving your mortgage to a **different lender**. The new lender pays off the old mortgage and you begin paying the new lender on their terms.

The process involves:

1. Application with the new lender

2. New affordability and credit assessment

3. Valuation (sometimes a desk or drive-by valuation rather than a full survey)

4. Legal work — conveyancers are required; many lenders offer a free legal service for straightforward remortgages

5. Completion, with the new lender redeeming the old mortgage

Full remortgage typically takes four to eight weeks from application to completion.

Comparing the Costs

Product Transfer

• **No legal fees** — no conveyancer required
• **No valuation fee** — lender already holds the property details
• **Arrangement fee** — may apply on the new product (typically £0–£999)
• **Broker fee** — if using a broker; some brokers charge for product transfer advice, some do not
• **Total typical cost:** £0–£999

Remortgage

• **Legal fees** — typically free if you use the lender's appointed solicitors; £300–£500 if using your own
• **Valuation fee** — typically free on remortgage; occasionally a small charge
• **Arrangement fee** — as with product transfer, varies by product
• **Broker fee** — many whole-of-market brokers charge a fee (£0–£500 typically)
• **Total typical cost:** £0–£1,500

The cost difference is real, and the rate difference must be large enough to justify switching costs. A rate 0.1–0.2% lower at a new lender saves roughly £200–£400/year on a £200,000 mortgage — barely enough to cover switching costs in year one. A 0.5% difference saves approximately £1,000/year — switching pays back in under 18 months.

When Product Transfer Wins

**Rates are broadly comparable.** If the best product transfer rate from your existing lender is within 0.2% of the best remortgage rate in the market, staying is almost always better once costs are factored in.

**Speed matters.** If you are time-pressed, a product transfer can be completed in days rather than weeks. This is relevant if you are close to deal expiry and have not made arrangements in time.

**Your circumstances have not changed.** If your income, property value, and borrowing needs are unchanged, there is no particular advantage to the full assessment required by a new lender.

**Avoiding credit searches.** A full remortgage involves a hard credit search from the new lender. A product transfer with your existing lender typically does not.

When Remortgage Wins

**Significantly better rate elsewhere.** A rate difference of 0.4%+ in favour of a new lender usually justifies the switch after costs, particularly on larger balances.

**Your LTV has improved substantially.** If your property has risen in value significantly and/or you have made overpayments, your LTV may now qualify you for a materially better rate tier that your existing lender's product transfer does not reflect as generously.

**You want to borrow more.** If you need to release equity for home improvements or other purposes, remortgaging often provides more flexibility and a broader range of options than a product transfer.

**Better terms available elsewhere.** Overpayment allowances, offset features, portable products — these vary by lender, and a new lender may offer a product that suits your circumstances better.

The Broker's Role in the Decision

A whole-of-market broker can obtain both your existing lender's product transfer rates and the best available remortgage rates simultaneously. This is the cleanest way to make the comparison: the broker presents a like-for-like comparison of the best two or three options, including all fees, and advises on the best total cost of borrowing.

Many brokers are paid by the lender (procuration fee) and charge borrowers nothing for straightforward remortgage or product transfer advice. Others charge a flat fee. Either way, the comparison they provide typically identifies saving potential that justifies the engagement.
