What Flat Owners and Buyers Need to Know
Following the Grenfell Tower tragedy in 2017, fire safety in multi storey residential buildings has been under intense scrutiny across the UK.
In Scotland, this has led to two key assessment frameworks that buyers and owners should understand:
- The EWS1 (External Wall System Fire Review)
- The Single Building Assessment (SBA)
Both are designed to evaluate fire risk – particularly in buildings with cladding or complex external wall systems – and both can affect mortgage lending, insurance and resale.
At Neilsons, we regularly advise buyers and sellers on how these requirements impact transactions.
Here’s what you need to know.
What is an EWS1 Form?
An EWS1 form is a specialist fire safety certificate that assesses a building’s external wall system, including cladding, insulation and fire stopping measures.
It is completed by a suitably qualified fire engineer or chartered building Surveyor following an inspection of the building.
The purpose of the EWS1 is to confirm whether combustible materials are present and whether remedial works are required. The result helps mortgage lenders and insurers decide whether a property is acceptable security.
Although originally associated with high rise buildings, in practice some lenders request an EWS1 for lower rise flats as well, depending on construction type.
Key points:
- The EWS1 applies to the whole building, not individual flats
- It is usually valid for five years
- It is commissioned by building owners or factors, not individual sellers
- Without a satisfactory EWS1, many lenders will not proceed
What is the Single Building Assessment (SBA)?
Scotland is moving toward a Single Building Assessment approach, supported by the Scottish Government.
Unlike the EWS1 – which focuses mainly on external walls – the SBA is designed to be a more comprehensive fire safety review of an entire building.
It can include:
- External wall construction
- Internal fire protection (doors, alarms, smoke ventilation)
- Escape routes
- Compartmentation
The SBA is intended to provide one consistent, standardised assessment per building and to help identify any remediation required.
Over time, the SBA is expected to replace reliance on EWS1 forms in Scotland – although currently EWS1 remains widely used by lenders.
Which applies right now?
At present:
- EWS1 forms are still commonly requested by mortgage lenders and insurers
- SBAs are being rolled out progressively across Scotland
- Conveyancing practice continues to evolve as SBA coverage increases
In short: EWS1 remains the practical requirement for many transactions today, but SBAs represent the future framework.
Will remediation costs affect owners?
Possibly.
If an EWS1 or SBA identifies safety defects, remedial works may be required. Responsibility for these costs is still developing legally and politically and may depend on:
- The age of the building
- Warranty coverage
- Developer involvement
- Government funding schemes
- Title conditions
Flat owners and buyers should be aware that future assessments could lead to cost implications, even where an EWS1 is currently satisfactory.
This is particularly relevant for newer build flats.
What does this mean for buyers?
If you’re purchasing a flat:
- Your lender may require an EWS1
- Your solicitor must check whether any SBA has been carried out or is pending
- You should understand whether remediation is anticipated
- Future lending policy may change
A satisfactory EWS1 today does not guarantee that further assessment won’t be required later under the SBA framework.
This is why experienced local conveyancing advice matters.
Our Advice
Cladding and fire safety assessments are one of the most complex parts of modern Scottish conveyancing.
At Neilsons, we:
- Review EWS1 documentation carefully
- Check for pending or completed SBAs
- Explain lender requirements clearly
- Advise on future risk before you commit
- Highlight any potential financial exposure
Whether you’re buying or selling, we make sure you understand exactly where you stand.
In Summary
- EWS1 forms remain widely used by lenders in Scotland
- Single Building Assessments are being introduced as the long-term solution
- Remedial works may carry future cost implications
- Buyers should never assume a flat is unaffected without proper checks
If you’re unsure how cladding assessments affect your property or purchase, speak to your Solicitor early in the process.
