The STL Insurance Market in H2 2026: Fewer Insurers, Harder Terms, and What to Look For at Renewal

The specialist short-term let insurance market appears — in our own client caseload — to have contracted through 2025 and 2026. This is a commentary from what we see across renewals we handle, not a formal market survey. It flags what to look for when renewing to avoid ending up under-insured or with cover that quietly excludes the exposure that matters most.

In short: This is commentary from what we see in our practice, not a market survey. Based on the cases and renewals our clients have brought us, the insurance market for short-term let operators has hardened: specialist appetite has narrowed, premiums have moved up, and exclusions have widened in ways operators should not discover for the first time at claim stage. Operators renewing this year should read the policy schedule carefully, not just the summary.

The insurance market for short-term let operators is a market STL Solutions does not itself operate in - we are planning and legal consultants, not brokers. What we do see, though, are the downstream consequences when a client's cover turns out to be inadequate. Those consequences have become more common in the caseload we have handled through 2026.

What we are seeing at renewal

Three shifts are worth naming, based on the renewals our clients have brought us:

1. A narrower specialist market. Client experience suggests that fewer specialist STL underwriters are quoting than a year or two ago. That has pushed volume onto the remaining specialists and onto standard household insurers offering an STL endorsement, which is not the same thing. 2. Higher premiums. Renewals we have seen through H2 2026 have often come back materially above the equivalent 2024 premium. Uplifts of 20-40% are not unusual on the schedules our clients have shared with us. Larger uplifts have appeared on multi-unit portfolios and on properties in areas the underwriter identifies as high enforcement risk. 3. Wider exclusions. The most consequential change is not the premium but the small print. Exclusions we have seen appearing on schedules include: cover being void where the property does not hold a current STL licence (Scotland) or is not registered (Wales and, in due course, England); loss of rent cover excluded where the loss arises from local authority enforcement action; and public liability excluding claims arising from any use the underwriter deems unlawful.

Why this matters

Two of those exclusions bite hardest.

Where cover is void without a current licence or registration, an operator who is mid-application - a common situation given the delays many councils are running - can find themselves technically without cover on a live property. That is a serious position to be in and one that operators cannot always mitigate quickly.

Where the loss of rent cover excludes losses arising from enforcement action, an operator served with an Enforcement Notice who has to cease operating is left carrying the cost of the forced closure alone. That was the exact exposure a number of Scottish operators discovered they had in 2025 when Edinburgh's enforcement programme accelerated.

What to look for at renewal

We are not brokers and we do not recommend specific products. What we do suggest is that operators, at renewal, put five direct questions to their broker or insurer:

1. Is the cover void if the licence or registration lapses, is refused, or is pending? 2. Does the loss of rent cover respond to a forced closure arising from planning enforcement action? 3. Does the public liability cover respond to claims arising from a use the insurer subsequently deems unlawful? 4. Is any exclusion applied on the basis of the property being in a designated control area, Article 4 area, or similar? 5. Where a Certificate of Lawfulness is held, is the underwriter prepared to note that on the policy schedule?

Answers to those questions will tell an operator whether the cover they are paying for is the cover they think they are paying for.

The planning connection

Where a Certificate of Lawfulness is held for the use, the answers to several of the questions above become materially easier. A Certificate is durable, is not lost on lapse of a licence, and represents an authoritative finding that the use is lawful - which cuts through most of the "unlawful use" exclusions insurers now write.

This is not the only reason to hold a Certificate. It is, however, one of the less-discussed reasons and one that becomes more relevant as the insurance market hardens.

Making Tax Digital for Income Tax Hits Holiday-Let Owners from April 2026: The Compliance Overlap That Should Concern You

From April 2026, individual landlords with property income above the MTD threshold - including former FHL operators - are required to keep digital records and report quarterly to HMRC. On top of the abolition of the FHL regime this is the second material compliance imposition in two tax years, and the overlap of HMRC visibility with planning enforcement visibility should concern operators whose planning status is not clean.
