Transferee Lenders May Retain and Vary an Inherited Mortgage SVR; CCA Unfair-Relationship Remedies Cannot Reach Regulated Mortgages via “Related Agreements”

1. Introduction

Breeze & Ors v TSB Bank PLC [2026] EWCA Civ 32 is a Court of Appeal decision concerning so-called “mortgage prisoners” whose residential mortgages originated with Northern Rock plc and were later transferred (in 2016) to TSB, which administered them under the “Whistletree” brand.

The appeal arose from the determination of two preliminary issues by Thompsell J (then Deputy High Court Judge) in [2024] EWHC 2427 (Ch), both decided for TSB. The Claimants (392 borrowers) appealed.

Key parties

  • Claimants: 392 individual residential borrowers (“Whistletree Borrowers”), including some with “Together” packages (mortgage + linked unsecured loan).
  • Defendant: TSB Bank PLC (transferee lender/administrator of the mortgage portfolio).

Core issues

  1. Issue 1 (Contract): Whether TSB breached the express mortgage terms by charging interest using the “Whistletree SVR” (inherited from Northern Rock) rather than applying TSB’s “TSB SVMR” (a different TSB standard variable rate).
  2. Issue 3 (Statute): Whether CCA 1974, s 140A(5) bars a court from making an order under s 140B that affects (or is quantified by reference to) a regulated mortgage contract, even if the unfair-relationship claim is framed by treating an unsecured credit agreement as the “credit agreement” and the regulated mortgage as a “related agreement”.

2. Summary of the Judgment

The Court of Appeal dismissed the appeal on both issues:

  1. Issue 1: On the proper interpretation of Northern Rock’s General Conditions, TSB was entitled (as transferee) to continue to operate the inherited “Standard Variable Mortgage Base Rate” and to vary it under the contractual variation mechanism (Condition 7). TSB was permitted, but not required, to switch to one of its own standard variable rates under Condition 19.1.
  2. Issue 3: s 140A(5) is a categorical restriction: no order under s 140B may be made “in connection with” a regulated mortgage contract (an exempt agreement for these purposes). Borrowers cannot obtain repayment or variation relief relating to a regulated mortgage by “routing” the claim through an associated unsecured loan as the “credit agreement”.

3. Analysis

3.1 Precedents Cited

A. Contractual interpretation framework

The Court adopted the now-standard contextual approach, with primacy to the language used, as summarised in Lamesa Investments Ltd v Cynergy Bank Ltd [2020] EWCA Civ 821 at [18], drawing on:

  • Arnold v. Britton [2015] UKSC 36, [2015] AC 1619: emphasis on text; background is limited to what was known/assumed at contracting; courts do not rewrite bad bargains.
  • Rainy Sky SA v. Kookmin Bank [2011] UKSC 50 [2011] 1 WLR 2900: where two meanings are available, prefer the one consistent with business common sense (as at contract date).
  • Wood v. Capita Insurance Services Limited [2017] UKSC 24: balancing text and context; quality of drafting may affect the weight placed on textual analysis.

B. Standard form contracts

TSB invoked the standard form caution articulated by Lord Millett (dissenting) in AIB Group (UK) Plc v Martin [2001] UKHL 63, [2002] 1 WLR 94: standard wording should generally bear a stable meaning across usages, with limited scope for case-specific background. The Court regarded this principle as of limited relevance here because the Claimants’ case was itself based on standardised wording rather than bespoke background.

C. Contra proferentem and consumer-favourable construction

The Claimants relied on statements supportive of leaning towards consumers where standard terms are used:

  • Re Drake Insurance plc [2001] Lloyd's Rep IR 643 (Neuberger J) on the (limited but sometimes material) force of contra proferentem, especially in insurance contexts.
  • Foxtons v Bicknell [2008] EWCA Civ 419, [2008] 2 EGLR 23 (Lord Neuberger) suggesting a tilt in favour of consumers when construing an expert’s standard terms in domestic settings.

The Court accepted these were arguable statements of the law but emphasised scepticism about the rule’s decisiveness:

  • K/S Victoria Street v House of Fraser Stores Management Ltd [2011] EWCA Civ 904, [2012] Ch 497 at [68] (contra proferentem rarely decisive in commercial contract interpretation).
  • Triple Point Technology Inc v PTT Public Co Ltd [2021] UKSC 29, [2021] AC 1148 at [111] (Lord Leggatt expressing scepticism about the “independent authority” of contra proferentem).

The Claimants also invoked regulation 7(2) of the Unfair Terms in Consumer Contracts Regulations 1999 (consumer-favourable interpretation where a written term is in doubt). The Court held that these aids did not advance the Claimants’ case because there was no relevant “doubt” about the meaning.

D. Statutory interpretation approach

For Issue 3 the Court cited modern purposive-contextual interpretation authority:

  • R (Project for the Registration of Children as British Citizens) v Secretary of State for the Home Department [2022] UKSC 3, [2023] AC 255
  • News Corp UK & Ireland Ltd v Commissioners for His Majesty's Revenue and Customs [2023] UKSC 7, [2024] AC 89
  • R (N3) v Secretary of State for the Home Department [2025] UKSC 6, [2025] 2 WLR 386
  • Darwall v Dartmoor National Park Authority [2025] UKSC 20, [2025] AC 1292

E. Unfair relationships: breadth and remedial discretion

The Court treated Smith v Royal Bank of Scotland [2023] UKSC 34, [2024] AC 955 as the leading guidance on ss 140A–140C: the “unfair relationship” test is broad and holistic, and the s 140B menu is wide once jurisdiction is engaged. It also cited Plevin v Paragon Personal Finance Ltd [2014] UKSC 61, [2014] 1 WLR 4222 (Lord Sumption) describing s 140A as “extremely broad”. The significance here, however, was that even broad remedial discretion is subject to any express statutory limitation—namely s 140A(5).

F. Meaning of “in connection with”

To frame the breadth of the connecting phrase, the Court referred to:

  • Campbell v Conoco (UK) Ltd [2002] EWCA Civ 704, [2003] 1 All ER (Comm) 35 (Rix LJ: “in connection with” is among the widest connective phrases).
  • Lessees and Management Company of Herons Court v Heronslea Ltd [2019] EWCA Civ 1423, [2019] 1 WLR 5849 (Hamblen LJ: such words take colour from statutory context).

3.2 Legal Reasoning

Issue 1: Transfer, “we”, and two mechanisms for rate-setting

The contractual architecture mattered:

  • The Offers incorporated Northern Rock’s “Mortgage Offer General Conditions”. “We/us/our” was defined to include Northern Rock and any transferee entitled to Northern Rock’s rights.
  • “Standard Variable Mortgage Base Rate” was a defined concept: the base rate decided “from time to time” by “we” for calculating interest on the mortgages governed by the General Conditions.
  • Condition 7 was the operative variation clause: the lender could reduce the base rate at any time (7.1) and increase it if specified reasons applied (7.2).
  • Condition 19.1 permitted transfer “including the right to set the Interest Rate”, and additionally provided that the transferee may set interest by reference to the transferee’s “own (or one of its own) standard variable mortgage base rates”.

The Court’s core reasoning was sequential:

  1. Pre-transfer meaning: the “Standard Variable Mortgage Base Rate” is a concrete numerical rate used for the portfolio subject to the General Conditions, and it is variable via Condition 7. Nothing in Condition 7 makes that variability dependent on any later adoption of another lender’s house rate.
  2. Effect of transfer: once transferred, the transferee becomes “we” for contractual purposes, and therefore inherits the contractual power to vary the Standard Variable Mortgage Base Rate under Condition 7.
  3. Two distinct mechanisms: (a) continuing with (and varying) the inherited Standard Variable Mortgage Base Rate under Condition 7; and (b) optionally switching (under Condition 19.1) to one of the transferee’s own standard variable mortgage base rates, which then becomes the contractual “Standard Variable Mortgage Base Rate” for the transferred loans and is thereafter varied under Condition 7.

On this structure, the Claimants’ “mandatory switch” theory failed: the contractual text made switching permissive, not obligatory. The Court also noted a practical incoherence in the Claimants’ approach: if the transferee could not vary the inherited rate unless it first adopted its own SVR, the inherited “variable” rate would become effectively fixed unless and until a switch occurred—an outcome unsupported by the language and commercially implausible.

The Court rejected the Claimants’ subsidiary points (“standard” must mean portfolio-wide across the transferee; “prevailing” in Special Condition 10; “herd protection” expectations; contra proferentem; UTCCR reg 7(2)), largely because they could not displace the clear contractual mechanics and, in some instances, were inconsistent with concessions the Claimants made (notably that TSB could have continued charging the inherited numerical rate).

Issue 3: s 140A(5) as a categorical jurisdictional bar, not an evadable “gateway”

The Court treated the statutory scheme as follows:

  • s 140A(1) creates jurisdiction to make a s 140B order “in connection with a credit agreement” if the court finds an unfair relationship.
  • s 140A(5) then removes that jurisdictional power where the credit agreement is an exempt agreement by virtue of RAO art 60C(2)— i.e. including regulated mortgage contracts.
  • The same phrase (“an order under section 140B … in connection with a credit agreement”) appears in ss 140A(1), 140A(5) and 140B(1) and should bear a consistent meaning across them.

The Claimants’ proposed workaround was to treat the unsecured “Together Loan” as the “credit agreement” and the regulated mortgage as a “related agreement”, then seek repayment relief measured by, or directly affecting, sums paid under the mortgage. The Court characterised this as attempting to obtain “by the back door” what Parliament barred “by the front door”.

Construing “in connection with” broadly (but contextually), the Court held that an order requiring repayment of sums paid under a regulated mortgage is an order “in connection with” that regulated mortgage—hence barred by s 140A(5). The bar is not avoided because the unfairness assessment may consider related agreements: consideration of a regulated mortgage as a related agreement does not entail that the court may grant remedies that operate upon (or are quantified by reference to payments under) the regulated mortgage.

The Court considered legislative history (transition from extortionate credit bargains to unfair relationships, the 2004 introduction of FSMA mortgage regulation, and later consolidation into the RAO) but concluded the decisive point was the wording and policy of the current regime: regulated mortgage contracts sit within a separate regulatory framework (FSMA/MCOB), and s 140A(5) expresses a categorical exclusion from the unfair-relationship remedial power.

3.3 Impact

A. Mortgage transfers and SVR administration

The decision materially strengthens transferee lenders’ ability to administer acquired mortgage books on an “inherited SVR” basis, including varying that inherited rate pursuant to the original contract’s variation clause, without being compelled to align transferred borrowers with the transferee’s other SVR cohorts. It underlines that (absent different drafting) transfer clauses may confer:

  • a continuation model (transferee steps into the transferor’s shoes and uses the existing contractual SVR mechanism); and
  • an optional harmonisation model (transferee may adopt one of its own SVRs).

B. Unfair-relationship litigation strategy for “Together” and similar structures

For borrowers with linked unsecured lending, the judgment significantly restricts the remedial reach of CCA unfair-relationship claims where a regulated mortgage is involved. Even if the unsecured loan is the “credit agreement” and the mortgage is a “related agreement”, relief cannot be fashioned so as to require repayment of mortgage payments or alter the mortgage terms, because that would be “in connection with” a regulated mortgage contract and therefore barred by s 140A(5).

C. Regulatory boundary clarity (CCA vs FSMA/MCOB)

The judgment reinforces a hard boundary: where Parliament has placed regulated mortgage contracts under FSMA/MCOB, courts should not permit the CCA unfair-relationship regime to be used to obtain mortgage-specific remedies through drafting characterisations or remedial framing.

4. Complex Concepts Simplified

  • SVR (Standard Variable Rate): a lender’s variable interest rate that can change over time (often influenced by the Bank of England base rate).
  • Contractual “Standard Variable Mortgage Base Rate” (as defined here): the particular base rate the contract uses for the mortgage book governed by the General Conditions; it is not automatically the same as any other rate the lender offers elsewhere.
  • Transfer/assignment of mortgages: the original lender can transfer its rights (including rate-setting rights) to another entity; the transferee then becomes the contractual “we”.
  • Contra proferentem: if a contract term is genuinely ambiguous, it may be interpreted against the party who drafted/relies on it. The Court stressed it is not a substitute for careful reading and does not apply where the meaning is clear.
  • UTCCR 1999 reg 7(2) (consumer-favourable interpretation): if a written term is in doubt, the interpretation most favourable to the consumer prevails. The Court held there was no relevant doubt on Issue 1.
  • CCA “unfair relationship” (ss 140A–140C): a broad judicial power to give relief where the relationship arising out of a credit agreement is unfair. But it is limited by statutory carve-outs, including s 140A(5).
  • Regulated mortgage contract (FSMA): a mortgage regulated under FSMA and subject to FCA rules (including MCOB). Under s 140A(5), courts cannot make CCA unfair-relationship orders “in connection with” such mortgages.
  • “Related agreement”: an agreement linked to the main credit agreement (e.g., a linked mortgage to an unsecured loan). The court may consider it when assessing unfairness, but (per this case) cannot grant barred remedies that operate on a regulated mortgage.

5. Conclusion

Breeze & Ors v TSB Bank PLC [2026] EWCA Civ 32 establishes two practically important propositions:

  1. Transferred mortgage SVRs: where standard conditions provide (i) a general power to vary the contractual base rate and (ii) a permissive option for a transferee to adopt one of its own SVRs, the transferee is not obliged to switch borrowers onto its own SVR and may continue and vary the inherited contractual SVR under the original variation clause.
  2. CCA s 140A(5) carve-out: courts cannot use the CCA unfair-relationship remedies to grant relief affecting regulated mortgage contracts, even indirectly through an associated unsecured credit agreement and “related agreement” analysis; remedial creativity cannot circumvent the statutory exclusion.

The judgment therefore consolidates contractual orthodoxy in the interpretation of rate-setting terms in transferred mortgage books, and it draws a firm remedial boundary between the CCA unfair-relationship regime and FSMA/MCOB-regulated mortgages.
