Specialist property valuations

What should you check when valuing a flat with cladding concerns?

Cladding concerns can raise separate questions about the building, funding and a lender's assessment. A sale price or online estimate cannot answer them all. Identify the actual documents and professional requirements before deciding how much confidence to place in the price.

This is an estimate from comparable sales, not a RICS or mortgage valuation, and not a survey.

Four separate building questions

Find out what is known about this building

Ask which concern is being described and which document supports it. A general statement about a development or a photograph of an exterior is not a property-specific assessment of safety or saleability.

Government guidance for Help to Buy homes explains that certain cladding circumstances can require specialist valuation work. That is guidance for the relevant scheme, not a universal instruction for every flat or mortgage application.

Keep the property, building and scheme clearly identified. Ask the seller or managing agent for the relevant current records and pass material questions to your advisers.

Give each document the right job

Building assessments, work proposals, funding information and lender requirements can answer different questions. Our suggestion is to make a list showing what each document establishes, its date and what it leaves unresolved.

An assessment should not be treated as a payment commitment, and a statement about funding should not be treated as proof that all work has been completed. Ask the relevant professional to explain the actual position.

Four separate building questions

What is the assessment?; What work is proposed?; What funding is documented?; What does the lender require?. Read the evidence together before making a property-specific judgement.

If the flat's broader leasehold price is your concern, assessing a leasehold flat's asking price covers other evidence. Do not let a generic leasehold comparison replace a building-specific investigation.

Ask the lender about its own process

Mortgage and remortgage valuations explains the lender's purpose. Supply the actual information requested. Do not assume another buyer's experience with a different lender establishes the answer for your application.

If an assessment comes back below the agreed price, what a mortgage down valuation means addresses the separate next decision. A funding question is not solved simply by obtaining a higher estimate elsewhere.

Keep costs and uncertainty visible

Ask your conveyancer and the relevant building parties about documents concerning liabilities, protections and proposed work. Rules and schemes can differ by geography and circumstance. This article does not determine whether you qualify for a particular protection.

Before assessing a premium or discount, identify what is known. An unresolved liability cannot be transformed into a reliable allowance by selecting a convenient percentage.

Track each building-safety question

CheckWhat to establish
Document ownerIdentify who holds the relevant building information.
Assessment statusCheck whether the available report addresses the lender question.
Works positionAsk what has been decided and what remains uncertain.
Cost responsibilityUse legal advice to establish the position for the particular flat.

A document from another building is not evidence about this one. Nor does the existence of a report settle every question about works, funding or lending. Keep a list of unresolved matters and the person responsible for answering each. Price research can continue, but a transaction decision should recognise the consequences of information which is still missing.

When a new document arrives, check whether it answers the original question or creates a different one. Record its author and scope. A building-wide document and a flat-specific legal or funding question may require different advisers; do not merge their conclusions into a single statement that the flat is ready to sell.

Checklist: Identify building and flat; Record dates and authors; Separate findings from funding; Ask about unresolved liabilities; Confirm the lender’s process
Build a document register

Identify building and flat; Record dates and authors; Separate findings from funding; Ask about unresolved liabilities; Confirm the lender’s process. Record the supporting document and any unanswered question.

Review the comparable evidence carefully

A sale in another block may differ materially in its documents and building circumstances. Even a sale in the same building may involve different timing or evidence. Ask why it is relevant and what assumptions support the comparison.

The useful question is not whether flats with cladding concerns have one market price. It is whether the specific transaction evidence and professional information support a decision about this flat.

Ask for clarification before treating an unexplained valuation as an answer to the building issue. A precise number does not establish that the relevant risk has been investigated.

Use PMD only for the appropriate research task

PMD can help organise available comparable and market evidence for eligible homes. It does not certify building safety, funding protection or lender acceptance. Confirm scope and read the methodology limits.

For a purchase, use the report alongside the appropriate legal, building and lending evidence. If those questions remain open, address them before relying on the price.
