Clear guidance on non-standard home insurance in the UK, including what it covers, who needs it, common pitfalls like underinsurance, costs, and smart steps to secure suitable protection.
A clear guide to cover for unusual UK homes
Non-standard home insurance protects properties that fall outside the typical insurer profile. In Great Britain this often includes listed buildings, homes with thatched or timber-framed construction, properties with a significant flat roof area, houses in flood or subsidence zones, or high-value homes with ornate features and higher rebuild costs. Standard policies may refuse these risks or apply exclusions that leave dangerous gaps in protection. A specialist policy recognises the true nature of the property and funds the repairs it genuinely needs.
Many owners only discover their home is classed as non-standard when a quote is declined or a claim is queried. Others learn during a mortgage application, where lenders want proof that suitable cover is available and affordable. Specialist insurers assess the construction, location, previous claims, and any periods the home is unoccupied. Where mainstream markets say no, these providers can build tailored solutions, including cover for legal repair requirements on listed buildings.
A rising share of UK brokers report more enquiries for complex properties, while a meaningful portion of quotes are declined by standard insurers without signposting to specialists. At the same time, underinsurance is a growing issue across the UK, with many homes insured for less than their true rebuild cost. That gap can severely reduce a claim payment. This guide sets out what non-standard home insurance includes, where it is limited, and how to buy with confidence. It is designed to help you ask the right questions and avoid unpleasant surprises at claim time.
Insurance should meet the real cost of rebuilding your home - not an optimistic estimate.
What is included - and what is not
Specialist home insurance for non-standard properties typically covers buildings, and optionally contents, against insured events such as fire, escape of water, storm, flood, theft and liability claims. It is tailored to the property’s features. For example, a listed cottage may include cover for heritage-compliant materials and specialist trades. A house with historic subsidence might include subsidence cover with a higher excess and strict maintenance conditions. Second homes or properties left empty for extended periods may include unoccupied cover that continues protection beyond the 30-day limit many standard policies apply.
Exclusions still apply. Wear and tear, poor maintenance, and gradual deterioration are not usually insured. Flood or subsidence may be excluded or restricted if the risk is severe or undeclared. Unoccupancy often carries conditions such as regular inspections, water systems being drained in winter, and security standards for doors and windows. High-value items may require separate specification and agreed limits. As with any policy, misrepresentation or non-disclosure can invalidate cover.
A typical claim follows a clear path. You contact the insurer or claims handler as soon as safe to do so, provide details and evidence, and allow access for inspection. For listed or unusual constructions, the insurer may appoint specialists to scope compliant repairs. Settlement may be by cash or managed repair. Excesses apply and can differ by peril - for example, higher for subsidence or flood. Being transparent about the property and its use improves the likelihood of a smooth claim.
Who benefits most from this cover
This insurance suits UK homeowners whose properties sit outside standard criteria - including thatched or timber-framed homes, listed buildings, properties with significant flat roofs, homes in higher flood or subsidence risk areas, second homes, and high-value houses with bespoke finishes. Owners with a poor claims history or long unoccupied periods can also benefit from specialist terms designed for their circumstances.
If your home is of standard construction, in a low-risk area, and continuously occupied, a mainstream policy may be sufficient and more economical. However, if you are unsure whether your home is non-standard, seek confirmation before buying. The right classification prevents declined claims and helps satisfy mortgage lender requirements.
Choosing the right level of protection
-
Core buildings only
- Covers the structure - walls, roof, fixtures and permanent features - against insured perils. Suitable where contents are minimal or insured elsewhere. May include heritage-compliant repairs and higher sums insured for complex rebuilds.
-
Buildings plus contents
- Adds cover for your belongings against theft, fire, flood and similar events. Ideal for main residences or well-furnished second homes. Check single-item limits and specify high-value items to avoid shortfall.
-
Enhanced comprehensive
- Includes higher buildings sums insured, accidental damage to buildings and contents, alternative accommodation at realistic local rates, and extended garden or outbuildings cover. Often chosen for high-value or architect-designed homes.
-
Optional add-ons
- Accidental damage - useful for families and busy homes.
- Personal possessions away from home - covers items while travelling in the UK and abroad.
- Home emergency - rapid response for issues like boiler breakdowns or plumbing leaks.
- Legal expenses - support for property disputes or liability defence.
- Unoccupied property extensions - tailored periods beyond 30 days with inspection requirements.
- Valuables and fine art - specified items with professional valuations and specialist repair or replacement terms.
-
Higher excess options
- Voluntary excess can reduce premiums, but ensure affordability if you need to claim. Peril-specific excesses often apply for subsidence and flood - plan for these in your emergency fund.
Match your sum insured to a professional rebuild estimate - not the market value.
Cost and what drives it
Typical ranges vary by risk profile. Expect higher premiums where rebuilds are complex, risks are elevated, or unoccupancy is extended. The table shows common trends - not guaranteed prices.
| Factor | Typical impact on price | Notes and UK considerations |
|---|---|---|
| Construction type | Medium to high | Thatched and timber-framed often cost more due to fire risk and specialist trades. |
| Listed status | High | Heritage-compliant materials and methods increase rebuild cost and time. |
| Flood or subsidence risk | High | Higher excesses, stricter maintenance terms, and pricing reflecting local data. |
| Rebuild sum insured | High | Underinsurance reduces claims. Accurate valuations protect outcomes. |
| Unoccupancy | Medium to high | Cover can continue beyond 30 days with inspections and security conditions. |
| Contents value and valuables | Medium | High single items require specification and proof of value. |
| Claims history | Medium | Multiple or recent claims increase premiums and excesses. |
| Security and maintenance | Low to medium | Approved alarms, locks, and roof or drainage upkeep can help pricing. |
| Example annual ranges | Smaller non-standard homes | Traditional or high-spec homes |
|---|---|---|
| Indicative premium band | £300 - £900 | £1,000 - £2,500+ |
Can you apply - and what insurers may ask for
Most UK homeowners can apply, including freeholders, leaseholders responsible for the building, and buyers needing cover for mortgage purposes. Insurers normally ask about construction type, roof materials, the percentage of flat roof, age of the property, any heritage status, past or current subsidence or flooding, security features, occupancy pattern, and recent claims. You may be asked for surveys, structural engineer reports, or flood history, especially where risks are known. For high-value contents or fine art, expect valuations and photographs. Common reasons for decline include undisclosed structural movement, misrepresented unoccupancy, severe ongoing disrepair, or rebuild sums that cannot be validated. Being candid and providing documents early helps the insurer price fairly and keeps claims valid.
From quote to claim - simple steps
- Gather details on construction, roof type, flat roof percentage, and listed status.
- Obtain a professional rebuild estimate or use a reputable calculator tool.
- Request quotes from specialist insurers or brokers experienced in complex risks.
- Compare cover limits, exclusions, and excesses - not just the premium.
- Disclose unoccupancy, claims, and prior subsidence or flood events in full.
- Choose add-ons that match your use, valuables, and risk tolerance.
- Keep documents, valuations, and inspection logs ready for potential claims.
- Report incidents promptly and follow the insurer’s guidance on repairs.
Weighing it up - strengths and trade-offs

| Higher buildings sums insured to reflect true rebuild costs | Some risks may be excluded or sub-limited in severe areas |
| Experienced claims handlers for complex homes | More documentation needed - surveys, valuations, photos |
| May satisfy lender requirements for difficult properties | Limited insurer choice compared to standard market |
Key checks before you commit
Before buying, read the policy schedule and wording carefully. Confirm the buildings sum insured reflects a current rebuild estimate, including professional fees and debris removal. Check peril-specific excesses for subsidence and flood, and verify any inspection or security conditions during unoccupied periods. Look closely at exclusions for gradual damage, wear and tear, and maintenance. Review single-item limits for valuables and list items that exceed them. Ask how alternative accommodation is calculated for your local area. Finally, consider renewal pricing and how future claims could affect your premium and excess.

Frequently asked questions
Q: What counts as a non-standard home? A: Any property that sits outside typical insurer criteria - for example, listed buildings, thatched or timber-framed homes, significant flat roofs, high flood or subsidence risk, or extended unoccupancy. Insurers assess each case individually.
Q: Why are premiums higher for some traditional homes? A: Specialist materials and trades increase rebuild costs, and fire or water damage can be complex to remedy. Pricing reflects these higher risks and the need to use heritage-approved methods where required.
Q: Can I get cover if my home is often empty? A: Yes, many specialist policies include unoccupied options beyond 30 days. You may need regular inspections, winter draining of systems, and enhanced security to keep cover valid during empty periods.
Q: How do I avoid underinsurance? A: Base your buildings sum insured on a professional rebuild estimate, not market value. Update it for inflation and any renovations. Review contents limits and specify high-value items with current valuations.
Q: Will a previous subsidence claim stop me getting insurance? A: Not necessarily. Some insurers will consider properties with historic or remediated subsidence, often with higher excesses and maintenance conditions. Full disclosure and documents from engineers help the assessment.
Q: Do I need a broker? A: You can approach specialists directly, but an experienced broker can place complex risks efficiently and compare options. This is helpful where mainstream insurers decline or apply restrictive terms.
What to do next
Take stock of your property’s construction, risks, and how you use the home. Gather valuations and any reports. Compare quotes from specialist providers, focusing on sums insured, conditions, and excesses as much as price. Move at your own pace and choose cover that matches real-world repair costs.
