Historical mortgage lender requirements: missing building regulations

Not by itself. The general instruction expressly contemplates the situation. It requires all reasonable steps, by appropriate searches and enquiries, to ensure the property has the benefit of any necessary planning consents and building regulation approval for its construction and any subsequent change, and that there is no evidence of a breach. It then provides that where there is evidence of a breach but, in the conveyancer’s professional judgment, there is no reasonable prospect of enforcement action, and following reasonable enquiries the title is good and marketable and an unqualified certificate of title can be given, the lender will not insist on indemnity insurance and the conveyancer may proceed. So the questions are whether that judgment was properly available on the facts, what enquiries were made, and what the lender’s own answer required to be reported. The dated record establishes the last of those.

It addresses one risk, not the underlying position. An indemnity policy typically responds to the consequences of enforcement action in respect of unauthorised work. It does not obtain approval, and it does not establish that the work was properly done. Several published lender answers make that distinction expressly, requiring formal confirmation that the property is structurally sound and still suitable security, and stating that an indemnity policy will not replace the requirement for that check. Others permit insurance where subsequent changes were made 10 or more years ago and no consents are in place, provided the valuation report does not highlight major concerns or negative commentary. Whether a particular policy met a particular lender’s published requirements on a particular date is a question the dated record can be checked against.

It does in several published answers, though not in the same way in each. Enforcement powers in respect of unauthorised work are subject to statutory time limits and conditions, so exposure depends on what was done, when, and under which regime; that is a legal question on the facts rather than one the archive answers. What the archive shows is how lenders responded to it. One group of answers permits indemnity insurance where subsequent changes were made 10 or more years ago and no consents are in place, subject to the valuation not raising concerns, and requires the conveyancer’s recommendations where a breach is still within any applicable enforcement period. Those are examples from particular dated answers rather than a panel-wide rule.

No. The fact that a mortgage proceeded does not, by itself, establish that the lender’s requirements were met or that every relevant matter was reported. The dated instructions need to be compared with the searches and enquiries, the valuation, any lender approval and what was actually done. On this topic that comparison matters more than most, because the general instruction turns on a judgment the conveyancer had to make and, where an unqualified certificate of title could not be given, on a report to the lender.

A contact-point answer is common, and it is not the same as having no requirement. In the most recent scan, of the 136 profiles carrying the reporting question under the number used for counting, 21 answers contained specified wording about building regulations, indemnity insurance, retrospective consent or completion certificates. That is a wording search rather than a review of every answer, so it does not establish that the remaining answers contain no substantive requirement expressed differently. Where an answer gives only a contact point, the general obligations still applied, including the conveyancer’s judgment on the prospect of enforcement action and the duty to report where an unqualified certificate of title could not be given. You receive the complete Part 2 record either way. Part 2 is the lender-specific component of the instruction framework: a transaction investigation must also consider the general Part 1 instructions applicable at the time, the mortgage offer and its conditions, and any case-specific correspondence. Where no express topic wording is identified, that should not be treated as establishing that the lender accepted the circumstance without restriction.

The answers have been amended throughout. Lexsure’s England & Wales records contain 199 recorded amendments to the reporting answer between 2009 and 2026, of which 30 are provisionally classified as having changed the practical requirement and the remainder as non-substantive. Because that answer carries other content in some profiles, those figures are not counts of building regulations policy changes alone. The provisional classification suggests that most recorded amendments changed contact or routing details rather than the requirement itself. Such amendments could change the applicable requirement; their effect on a particular transaction depends on the instructions and timing relevant to that transaction. Either way, a lender’s current published policy is not evidence of what it required on an earlier transaction date.
