What Santander requires on buy-to-let conveyancing
On buy-to-let conveyancing a firm is acting for the borrower and for Santander at once, and the two sets of instructions do not always ask for the same things.

Why Santander takes an interest in buy-to-let conveyancing
Conveyancing on a property bought to be let rather than occupied. Lender requirements differ from residential lending, and Part 2 of the Handbook sets out what each lender expects on tenancies, licensing and permitted occupiers.
This page describes buy-to-let conveyancing as a process. It deliberately stops short of reproducing any lender's own answer, because Part 2 is amended without notice and a stale copy on a page someone acts on is worse than no copy at all.
Most of what goes wrong on buy-to-let conveyancing is not the drafting. It is an assumption about what Santander would accept that turned out to be an assumption about what the last lender accepted, and it surfaces late enough to move a completion date.
What has to be in place
The tenancy that came with the house
Buying tenanted is a different transaction from buying vacant. The agreement, the protected deposit, any arrears and any notice already served all transfer with the property, and a lender that would fund the same house empty may decline it occupied.
The licence nobody checked
Where a selective or additional licensing scheme covers the address, letting without the licence is an offence and can cost the landlord a rent repayment order. Lenders increasingly require the licence rather than the intention to apply for one.
The lease that says no
A leasehold flat may forbid subletting outright, permit it only with the landlord's written consent, or allow it subject to a fee and a notice. That restriction sits in the lease and binds the owner whatever the mortgage says.
The relative moving in
Letting to family is the most common way a buy-to-let borrower breaches their conditions without realising, because it feels like a private arrangement rather than a tenancy. Some lenders offer a regulated product for exactly this and most simply prohibit it.
How often Santander moves the answers above
Some lenders revise their requirements most years and some leave them alone for a decade. These figures place Santander between those.
Counted from the Lexsure Part 2 change record. Santander has changed its Part 2 in 10 of the 10 years to 2026, most recently in 2026. Counted from the Lexsure Part 2 change record. A lender that revises Part 2 often is not a worse lender than one that leaves it alone: what the figure describes is how far you can rely on what applied last time.
How Santander sets its own conveyancing requirements
A conveyancer on a Santander mortgage is acting for two clients at once, and the lender's half of the instructions is a published document: the UK Finance Mortgage Lenders' Handbook. It is the reason your solicitor asks for things that seem to have nothing to do with you.
Part 1
The industry-wide half
- Written once and applied to every lender in the scheme, which is why a conveyancer can act on a first matter for a lender they have never dealt with.
- It sets the investigation a firm has to carry out and the terms of the certificate of title it signs at the end of it.
- Amendments are consulted on and published, so a firm can see one coming.
Part 1 is the reason panel work is comparable between lenders at all.
Part 2
Where Santander answers for itself
- Every question Part 1 leaves to the lender is answered here, in Santander's own words: indemnity policies, new-build warranties, occupiers, retentions and the rest.
- It can be amended at any time and without notice, which is the whole reason a firm checks it per matter rather than per year.
- It is also where two lenders on the same transaction can want different things.
Nothing on this site reproduces a Part 2 answer. Read the current version before acting on any description of one.
Because Part 2 can be amended without notice, the useful question is how often a given lender amends it. Here is the answer for Santander.
Part 2 changes have been recorded for Santander in every year since 2009. A run that reaches the present is the case for reading the current version rather than working from the last matter, and it is the reason this site monitors Part 2 instead of reprinting it.
Counting the amendments rather than the years: Santander has made 730 changes to Part 2 sections since 2017, 41 of them in 2026. One amendment can touch several sections, so this counts section changes rather than distinct sections, and revisions that moved nothing but the document’s own date are left out.
Counted from the Lexsure Part 2 change record supplied on 3 August 2026, which holds the years a lender’s Part 2 was amended rather than what any amendment said. 2026 is a part year, because the extract was taken partway through it. A lender that revises Part 2 often is not a worse lender than one that leaves it alone: what these figures describe is how far a conveyancer can rely on what applied last time, which is why the current version is the one to check.
This site says which Part 2 question holds a lender-specific answer rather than reprinting the answer. A stale copy of a requirement, on a page someone acts on, is worse than no copy.
The points to put to Santander directly
Part 2 of the Handbook carries each lender's own requirements and its overrides of Part 1, and it is amended without notice. These are the points where the answer is Santander's rather than general practice:
- Whether the property may be let at all under the lease, and on what conditions
- The tenancy agreement the lender expects, and its minimum and maximum term
- Whether an inherited tenant is acceptable and what has to be produced
- Whether a licence must be granted, applied for, or neither, before funds are released
We do not reproduce Part 2 here. It is lender-specific, it changes without notice, and a stale copy of it on a page a conveyancer relies on is worse than no copy at all. LM04 tracks those changes.
