Not all rental properties are built the same—and insurers know it.
Listed buildings, thatched roofs, flat roofs, non-standard construction, steel or timber frames, older terrace conversions, mixed-use buildings, and architecturally unusual properties all sit outside the “standard” underwriting box.

These properties often require specialist placement and deeper technical knowledge to insure correctly. Without the right broker support, landlords can face higher premiums, unexpected exclusions, limited insurer appetite, or even outright refusal of cover.

As we approach 2026, insurers are sharpening their focus on construction risk, fire resilience, and rebuild accuracy. This means landlords with non-standard or complex properties need to be more proactive than ever in how they present and protect these assets.

On Day 15 of our 20-day series, we explore the challenges of specialist risks and how NetRent, together with Clear Insurance Management, helps landlords secure the best cover, pricing and long-term stability for unique properties.

Why Non-Standard Construction Requires Expert Handling

Specialist properties present insurers with higher uncertainty, often due to:

• unusual construction methods

• increased fire or water damage risk

• heritage protection rules

• expensive or hard-to-source materials

• more complex repair processes

• specialist contractors required

• longer rebuild times

• building regulation constraints

These factors directly influence:

• premiums

• excesses

• insurer appetite

• indemnity periods

• claims handling

• portfolio attractiveness

In 2026, insurers are expected to apply even greater scrutiny to non-standard risks, making expert representation essential.

Common Types of Specialist Properties Landlords Need Help Insuring

1. Listed Buildings (Grade I, II, II)*

Challenges include:

• strict regulation on materials and methods

• specialist craftsmen needed

• extended rebuild times

• heritage officer involvement

• high variation in reinstatement cost

These properties require insurer partners with specific listed-building expertise.

2. Thatched Roof Properties

Often considered high-risk due to:

• fire exposure

• expensive materials

• rapid damage spread

• need for specialist repair teams

Insurers offering these risks often impose conditions around chimneys, electrics and fire safety.

3. Flat Roofs

Flat roofs are a major cause of water ingress claims.

Insurers may require:

• regular condition reports

• improved drainage

• maintenance records

• high-quality materials

Some will restrict cover depending on percentage area.

4. Non-Standard Construction

Including:

• timber frames

• steel frames

• wattle and daub

• concrete panels

• stone or cob

• prefabricated systems

Each requires tailored risk assessment and bespoke insurer selection.

5. Older Properties & Complex Conversions

Victorian, Georgian or Edwardian homes—especially when converted into flats or HMOs—often present:

• outdated wiring or plumbing

• structural variations

• higher escape-of-water exposure

• more complex claims histories

These properties require deeper underwriting understanding.

Why Specialist Risks Will Receive Increased Scrutiny in 2026

Insurers are signalling major focus areas for next year:

• construction fire resistance

• water ingress patterns

• building age & material resilience

• accurate rebuild valuations

• professional contractor use

• compliance with modern building standards

• drainage and roof condition documentation

Non-standard buildings naturally attract more detailed assessment.

Landlords with unique properties must therefore demonstrate:

• strong maintenance

• compliance documentation

• accurate rebuild data

• professional oversight

• proactive risk improvement

This is where NetRent and Clear add meaningful value.

The Risks of Inadequate Cover for Specialist Properties

Poorly placed specialist policies lead to:

• exclusions landlords didn’t realise applied

• reduced claims settlements

• significant gaps in rebuild sums

• costly reinstatement overruns

• disputes with contractors

• limited insurer choice at renewal

• higher premiums in future years

Correct specialist placement is not simply beneficial—it is essential for financial protection.

2026 Outlook: Why Now Is the Time to Prepare

Landlords with non-standard or complex properties should engage early to:

• document construction details

• obtain updated rebuild values

• correct occupancy declarations

• prepare compliance documentation

• implement risk improvements

• secure early underwriter engagement

These steps significantly improve insurer appetite during the 2026 renewal season.

The landlords who prepare now will secure:

• broader cover

• stronger negotiating power

• better premiums

• fewer restrictions

• more reliable long-term insurance relationships
