The Link Between Your Front Door and Your Insurance
Most homeowners understand that locks matter to insurers. Fewer appreciate that the door itself — its material, construction and independently verified security rating — can meaningfully influence insurance terms, premiums and the outcome of a claim. In an era of rising premiums and increasingly sophisticated burglary methods, the home insurance door security ratings recognised by UK insurers deserve closer attention.
This guide explains how insurers assess door security, which certifications carry weight, and how upgrading to a properly rated entrance door can improve your cover and potentially reduce your premium.
How Insurers Assess Door Security
Insurance underwriters evaluate property security as part of their risk calculation. The front door is a primary consideration because it remains the most common point of forced entry in UK residential burglaries. According to the Office for National Statistics, over 70 per cent of domestic break-ins involve entry through a door.
Insurers typically assess door security across several criteria:
- Lock type and rating — minimum five-lever mortice deadlock to BS 3621, or a multi-point locking system to equivalent standard
- Door material and construction — solid timber, composite and steel are viewed more favourably than hollow-core or uPVC
- Independent certification — doors tested and certified to recognised security standards carry the most weight
- Overall doorset performance — modern insurers increasingly consider the door, frame and hardware as an integrated system rather than assessing components in isolation
The shift towards doorset-level assessment is significant. A high-security lock fitted to a weak door and frame offers limited real-world protection — and sophisticated insurers understand this.
Which Security Ratings Do Insurers Recognise?
Not all security standards carry equal weight with UK insurers. The following certifications are the most widely recognised and the most likely to influence your terms.
PAS 24: The Baseline Standard
PAS 24 is the minimum security standard for entrance doors in new-build properties under Approved Document Q of the Building Regulations. It tests the complete doorset — door leaf, frame, hardware and locking mechanism — against a defined series of physical attack methods including bodily force, lever attacks and lock manipulation.
Most mainstream insurers accept PAS 24 as evidence of adequate door security. For standard residential policies, a PAS 24-certified doorset typically satisfies the insurer's requirements without further discussion.
SR Ratings: Beyond the Minimum
The Loss Prevention Certification Board (LPCB) issues Security Ratings under the LPS 1175 standard. These ratings represent a more rigorous and granular assessment than PAS 24, testing doors against progressively more determined and better-equipped attackers.
- SR1 — resists casual or opportunistic attack with basic tools
- SR2 — resists determined attack with a wider range of tools over a longer period
- SR3 — resists sustained, determined attack with professional tools and methods
An SR3-rated steel entrance door represents a level of physical security that exceeds the vast majority of residential requirements. It is the rating most commonly specified for high-value properties, listed buildings containing significant contents, and homes in areas with elevated burglary risk. Our security specification details the full testing methodology and performance criteria.
Secured by Design
Secured by Design is the official UK police security initiative. Products carrying the Secured by Design accreditation have been independently assessed and approved by the police service as meeting specific crime prevention standards. For insurers, Secured by Design certification is a strong, easily verifiable signal of genuine security performance.
Many insurers specifically reference Secured by Design in their policy documentation. Some offer explicit premium discounts for properties fitted with Secured by Design-accredited products. Others use it as a factor in their overall risk assessment. Either way, it is the single most widely recognised security mark in the UK residential insurance market.

Potential Premium Reductions
The relationship between door security and insurance premiums is real but rarely straightforward. Insurers do not typically publish a schedule of discounts by security rating. Instead, security improvements feed into the overall risk profile alongside factors such as location, property value, claims history and alarm systems.
That said, several patterns are consistent across the market:
- Upgrading from a non-certified door to PAS 24 can satisfy minimum security requirements that were previously unmet, potentially removing a loading or excess applied to the policy
- Secured by Design accreditation is the certification most likely to trigger an explicit discount, with reductions of 5-15 per cent reported by policyholders
- High-value home policies (typically properties insured for over one million pounds) often include specific security requirements — meeting or exceeding these can unlock preferred terms
- Bundled improvements — a new security-rated door combined with an alarm system and CCTV — create a cumulative effect on the risk profile that is greater than any single upgrade
The most effective approach is to inform your insurer or broker of the upgrade before installation and ask specifically what impact it will have on your terms. Obtain written confirmation of any premium adjustment.
What Documentation to Provide Your Insurer
When notifying your insurer of a door upgrade, comprehensive documentation strengthens your position both for premium negotiation and in the event of a future claim.
Prepare the following:
- Certificate of conformity — issued by the manufacturer confirming the doorset meets PAS 24, LPS 1175 or other relevant standards
- LPCB or equivalent certificate — if the door carries an SR rating, the LPCB certificate is the definitive proof
- Secured by Design licence number — if applicable, this allows the insurer to verify accreditation directly with the scheme
- Installation certificate — confirmation that the door was installed by the manufacturer or an approved installer in accordance with the tested specification
- Product specification sheet — detailing the door construction, locking mechanism, cylinder type and any additional security features
Retain copies of all documentation permanently. In the event of a claim, the ability to demonstrate that your door met or exceeded the insurer's requirements at the time of the incident is invaluable.
High-Value Home Insurance Requirements
Properties insured for contents above approximately two hundred and fifty thousand pounds, or buildings above two million pounds, typically fall into the high-value or high-net-worth insurance category. These policies are underwritten differently from standard home insurance, with more detailed security assessments and more specific requirements.
High-value home insurers routinely require:
- Security survey — a physical inspection of the property by an approved surveyor, who will assess all entry points including the front door
- Minimum lock and door standards — often specifying multi-point locking to PAS 24 or higher as a condition of cover
- Alarm and monitoring systems — typically NSI Gold or SSAIB-approved, professionally monitored
- CCTV coverage — increasingly standard for properties above certain value thresholds
An SR3-rated, Secured by Design-accredited steel entrance door satisfies and exceeds the door security requirements of virtually every high-value home insurer in the UK market. For properties across London, Buckinghamshire and Hertfordshire, where property values consistently place homes in this category, specifying the right door from the outset avoids the cost and disruption of retrospective upgrades demanded by a surveyor.
Making a Claim After a Break-In
The true test of your door's insurance value comes if the worst happens. In the aftermath of a burglary, the claims process includes an assessment of the property's security at the time of the incident. Insurers may reduce or reject a claim if the security measures in place did not meet the policy's stated requirements.
Key considerations:
- Policy conditions — if your policy specifies minimum lock or door standards and these were not met at the time of the incident, the insurer may have grounds to reduce the payout
- Evidence of forced entry — a security-rated door that has been physically breached provides clear evidence that the entry was forced, supporting your claim. An unrated door that shows no damage may raise questions about whether it was locked
- Police report — always obtain a crime reference number. The police report will note the method of entry and the condition of doors and windows
- Replacement specification — most insurers will fund replacement on a like-for-like basis. If your breached door was SR3-rated, the replacement should be specified to the same standard
A properly certified door protects your claim as effectively as it protects your home. The documentation trail from purchase through installation creates an evidence chain that supports your position throughout the claims process.
How Door Upgrades Affect Existing Cover
Upgrading your front door mid-policy is a material change to the risk profile and should be reported to your insurer. Failure to notify can, in theory, create a gap in cover — though in practice, a security improvement is unlikely to be viewed negatively.
The notification process is straightforward:
1. Contact your insurer or broker and describe the upgrade 2. Provide the documentation listed above 3. Ask whether the upgrade changes your premium, excess or policy terms 4. Obtain written confirmation of any changes 5. Update your home inventory and insurance schedule accordingly
Some insurers will adjust the premium mid-term. Others will note the improvement and apply any discount at renewal. A small number may require a re-survey for high-value properties. In every case, the act of notification protects you.
The Broader Security Equation
A front door does not exist in isolation. Insurers assess the overall security picture, and the most favourable terms come from a comprehensive approach:
- Rear and side doors — often the weakest entry points. Upgrading the front door while leaving a vulnerable back door undermines both security and insurance positioning
- Windows — ground floor and accessible upper floor windows should meet PAS 24 as a minimum
- Alarm systems — a monitored alarm system is the single most impactful security measure for insurance purposes after the door itself
- External security — lighting, CCTV, gating and landscaping that eliminates hiding spots all contribute to the risk profile
The front door is the starting point, not the finish line. But as the most visible and most frequently targeted entry point, it sets the standard for everything else.
Steel Doors and Insurance: The Summary
Steel entrance doors occupy a unique position in the insurance conversation. The material is inherently stronger than timber, composite or aluminium. When engineered into a complete doorset and tested to SR3 under LPS 1175, the result is a product that exceeds every residential security requirement any UK insurer currently imposes.
Combined with Secured by Design accreditation and ISO 9001 quality management certification, a bespoke steel entrance door provides documentation and performance that satisfies even the most demanding high-value home insurer. Explore our collection to see the range of designs available at this security level.
The investment in a security-rated door pays returns in three ways: genuine physical protection, favourable insurance terms, and a robust position in the event of a claim. Few home improvements deliver value across all three dimensions simultaneously.
Frequently Asked Questions
Will a new front door definitely reduce my insurance premium?
A door upgrade can reduce your premium, but the extent depends on your insurer, policy type and overall security profile. Secured by Design accreditation is the certification most consistently linked to premium reductions. Contact your insurer before installation to confirm what impact the upgrade will have on your specific policy.
What is the minimum door security standard for UK home insurance?
Most standard home insurance policies require a five-lever mortice deadlock to BS 3621 or a multi-point locking system of equivalent security. PAS 24 certification for the complete doorset satisfies this requirement and is the minimum standard mandated by Building Regulations for new-build properties.
Do insurers recognise the SR3 security rating?
Yes. The SR3 rating under LPS 1175 is issued by the Loss Prevention Certification Board, which is widely recognised across the UK insurance industry. SR3 significantly exceeds the security requirements of standard and most high-value home insurance policies. It is the rating specified for properties requiring the highest level of residential door security.
What happens if my door is broken into and it was not security rated?
If your policy specifies minimum security standards and your door did not meet them at the time of the break-in, your insurer may reduce the claim payout or, in some cases, decline the claim. Even without specific policy conditions, a non-certified door makes the claims process more complex and potentially less favourable.
Should I inform my insurer when I upgrade my front door?
Yes. Any material change to your property's security should be reported to your insurer. A door upgrade is a positive change that may reduce your premium or improve your terms. Failure to notify could theoretically create an issue if you need to make a claim, even though the improvement itself strengthens your position.
Is Secured by Design the same as PAS 24?
No. PAS 24 is a British Standards Institution published document that sets the minimum security performance standard for doorsets. Secured by Design is a police-backed accreditation scheme that requires products to meet PAS 24 (or higher standards such as LPS 1175) plus additional requirements. Secured by Design is the broader, more recognised certification in the insurance market.
