NatWest amended 14 sections of its UK Finance Lenders’ Handbook Part 2 requirements on 22 October 2026. Among the changes is a revision within section 6.6.3a concerning tenancy agreements.
The supplied amendment replaces a requirement concerning tenancy duration and a repossession break clause with wording focused on legal validity and the effect of the tenancy on the Bank’s security.
For conveyancers, the practical question is no longer answered simply by checking the agreement’s stated length and locating a break clause. The revised wording requires consideration of the tenancy’s legal effect in the relevant jurisdiction.
What has changed?
Section 6.6.3a is headed:
Does the lender require counterpart/certified copy tenancy agreement to be sent to you?
Within that answer, the previous wording stated:
The tenancy is no more than 3 years in duration and includes a break clause allowing the lender to end the tenancy agreement early, in the event of repossession.
The replacement wording states:
The tenancy agreement must be legally valid in the relevant jurisdiction and must not materially prejudice the Bank’s ability to enforce its security, obtain possession where permitted by law, or dispose of the property following repossession.
This article examines that supplied passage. The complete current answer, related Handbook provisions, mortgage offer and case-specific instructions must also be checked.
A different test for the conveyancing file
The previous passage specified two contractual features: a maximum duration and a break clause addressing repossession.
The replacement asks whether the tenancy is legally valid and whether it materially prejudices the Bank’s ability to:
- Enforce its security.
- Obtain possession where the law permits.
- Dispose of the property following repossession.
That wording calls for an assessment of the arrangement and its legal consequences. Finding a clause labelled “mortgagee protection” or “break clause” does not, by itself, establish that the instruction is satisfied.
Equally, the deletion of the quoted three-year restriction should not be presented as unrestricted approval of tenancies of any length or type. Other requirements may apply elsewhere in NatWest’s instructions or in the mortgage offer.
Why the relevant jurisdiction matters
The new wording expressly refers to legal validity in the relevant jurisdiction. A tenancy precedent or checklist suitable for one jurisdiction should not be assumed to work elsewhere.
In England, the Renters’ Rights Act reforms introduced a new assured periodic tenancy regime from 1 May 2026, affecting most existing private assured shorthold tenancies and new assured lettings within its scope.
The government’s Renters’ Rights Act overview for landlords explains the changes. Transitional arrangements, exclusions and the circumstances of the particular tenancy still need consideration.
This provides relevant legal context for reviewing tenancy instructions. It does not establish NatWest’s reason for making the amendment.
Conveyancers should avoid applying an old fixed-term checklist without considering the tenancy’s current legal status. The position in Wales, Scotland or Northern Ireland must be assessed under the law applicable there.
A contractual clause cannot replace the statutory possession process
The phrase “where permitted by law” is important. A tenancy provision cannot, simply by its wording, give the Bank rights that override applicable statutory protections or procedural requirements.
The review should consider the legal framework governing possession and enforcement, together with the particular agreement and circumstances.
The government’s guidance on grounds for possession in England includes information about mortgage-lender possession. The availability of a ground and its requirements should be assessed rather than assumed.
Where the effect of a tenancy is uncertain, obtain appropriate specialist advice or lender clarification as required. A statement that an agreement is “standard” is not a substitute for that assessment.
What should conveyancers check?
A practical review should establish:
- The applicable jurisdiction and tenancy regime: identify the law governing the arrangement and any relevant transitional position.
- The current documents: obtain the agreement and relevant variations, renewals or other documents affecting the tenancy.
- The actual arrangement: check whether the documents accurately reflect the occupation and terms disclosed.
- The effect on the security: consider whether the tenancy materially prejudices the Bank’s enforcement, lawful possession or disposal rights.
- The remaining instructions: read the complete NatWest answer alongside related provisions and the mortgage offer.
- Outstanding questions: identify any further enquiries, advice or referral needed before proceeding.
This is a suggested review structure, not an exhaustive statement of NatWest’s requirements.
Record the reasoning behind the conclusion
A file note saying “tenancy checked” gives another reviewer limited information about how the revised instruction was addressed.
A useful record identifies the documents considered, the applicable legal regime, any relevant issues, the enquiries made and the conclusion reached.
Where NatWest has been asked to consider a point, retain the report, supporting information and actual response. Our article on why a lender portal acknowledgement is not approval explains the distinction between receipt and a decision.
Does the change alter the requirement to send the tenancy agreement?
The supplied amendment concerns a passage within an answer whose heading asks whether a counterpart or certified copy must be sent to the lender.
That passage alone does not establish the complete document-submission requirement. Conveyancers should read the whole current answer before deciding what must be sent, retained or referred.
It would therefore be unsafe to infer from this extract either that every agreement must now be sent to NatWest or that submission is never required.
One amendment within a wider NatWest update
The tenancy wording forms part of an update affecting 14 Part 2 sections. Reviewing this passage should not replace checking the other amendments relevant to the matter.
For firms, the next steps are to update tenancy-review prompts, brief affected staff and identify live matters requiring reconsideration. The response should reflect the complete revised instructions and the circumstances of each transaction.
LENDERmonitor notifications provide a route for firms to enquire about monitoring changes to lenders’ mortgage instructions. Identifying an amendment should be followed by assessing its effect on the firm’s work.
Reviewing an earlier NatWest transaction? Check the earlier wording
This amendment illustrates why today’s Handbook cannot be used as a substitute for the instructions that applied to an earlier transaction.
Where a dispute concerns the acceptability of a tenancy, or what the conveyancer should have checked or reported, the dated instruction is an important part of the evidence.
The Lexsure National Westminster Bank archive provides access to historical lender-specific requirements. Our guide to investigating NatWest’s historical mortgage requirements explains why the relevant date matters.
The historical wording should be considered alongside the mortgage offer, tenancy documents, lender correspondence, conveyancing file and law applying at the time. An instruction’s existence, amendment or deletion does not, by itself, establish whether earlier advice was adequate.
