Buy-to-let conveyancing on a Principality Building Society mortgage
On buy-to-let conveyancing a firm is acting for the borrower and for Principality Building Society at once, and the two sets of instructions do not always ask for the same things.

Buy-to-let conveyancing, in plain terms
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.
Most of the delay on buy-to-let conveyancing comes from establishing what the lender wants before anyone starts drafting. Getting that answer early is usually worth more than any amount of chasing later.
Worth keeping in view throughout: on a mortgaged matter the firm answers to the borrower and to Principality Building Society at the same time. Most of the friction in buy-to-let conveyancing comes from those two sets of instructions asking for slightly different things.
What has to be in place
Tenancies
The lender will have requirements about the form of tenancy, its length, and who may occupy. Existing tenancies on a purchase have to be reported and checked against those requirements.
Licensing
Selective and additional licensing schemes are set by individual local authorities. Whether one applies is a local question and needs checking for the specific property.
Leasehold restrictions
A lease may prohibit or restrict letting. That restriction binds regardless of the mortgage product.
Occupation by the borrower
Buy-to-let terms generally exclude occupation by the borrower or their family. Where that is contemplated, it needs to be raised before completion, not after.
How often Principality Building Society moves the answers above
Some lenders revise their requirements most years and some leave them alone for a decade. These figures place Principality Building Society between those.
Counted from the Lexsure Part 2 change record. Principality Building Society has changed its Part 2 in 8 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.
Why a Principality Building Society panel solicitor asks for what it asks for
Much of what a solicitor asks for on a Principality Building Society matter is asked on the lender's behalf rather than on yours. The document that decides which questions those are is the UK Finance Mortgage Lenders' Handbook, and it is public.
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 Principality Building Society answers for itself
- Every question Part 1 leaves to the lender is answered here, in Principality Building Society'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.
Monitoring Part 2 for changes is what this site is for, so the monitoring record itself belongs on the page. This is Principality Building Society's.
Counting the amendments rather than the years: Principality Building Society has made 120 changes to Part 2 sections since 2017, 2 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 Principality Building Society directly
Everything above is general practice. The points below are the ones Principality Building Society decides for itself, and it publishes those decisions in Part 2 rather than applying them privately:
- The permitted tenancy types and any minimum or maximum term
- Whether the lender accepts an existing tenancy and on what evidence
- Any restriction on letting to a related party
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.
