A missing gas safety certificate doesn’t automatically mean you need another inspection. If you’re unsure how to get a replacement gas safety certificate, first try to recover the existing Gas Safety Record (CP12) from the engineer or business that carried out the check, or from your letting agent if they arranged it.
It’s understandable to worry that a missing record could affect your landlord responsibilities or a tenancy. The original issuer may be able to provide a copy if they can locate the record. If it can’t be found, or its status is unclear, a new gas safety check may be needed to establish the appliances’ current condition and create a new record.
This guide explains whom to contact first and what information to provide, when you may be able to get a copy, and when to arrange a new inspection with a Gas Safe registered engineer. You’ll also learn what to check and how to store the record, so you can keep property paperwork organised and provide the right document to tenants.
Key Takeaways
- Before arranging another check, search property files, emails, landlord portals and letting-agent records for the existing Gas Safety Record.
- To understand how to get a replacement gas safety certificate, identify who completed the original inspection and request a copy of that record.
- Use the inspection date and record details to establish whether the earlier check can be traced and whether a fresh inspection may be needed.
- When you find the record, check the property address, inspection date, appliances and recorded outcome, then store it with the property’s maintenance records.
- If you need a new inspection in London, Everything Heating Ltd provides Gas Safety Certificates (CP12).
Lost gas safety certificate? First establish whether you need a copy or a new check
A missing gas safety document doesn’t automatically mean the property needs another inspection. First establish whether the inspection took place and whether its record can be found. A copy reproduces an existing record. It can’t confirm the appliances’ condition today or change the date of an earlier check.
For landlords, it’s important not to treat a document you can’t find as proof that required checks are current. Check the inspection date and the record itself. If you can’t establish that the required check took place, or the record’s status is unclear, arrange a new check with a Gas Safe registered engineer. The Gas Safe Register is the UK’s official registration scheme for gas engineers.
What counts as a replacement gas safety certificate?
“CP12” is the term commonly used for a landlord gas safety record. It describes the record produced after a gas safety check, rather than a separate type of inspection. A replacement copy, or duplicate, is another copy of a record for an inspection that has already happened. The engineer or business that issued it may be able to provide one if they can locate the original record.
To help identify the right document, note the property address, approximate inspection date and issuing engineer or business. These details can distinguish one record from another, especially if you manage several properties or arranged checks through a letting agent.
When might a new gas safety check be the right next step?
If the issuer can’t locate the earlier record, you may not be able to confirm what was checked or when. A new inspection can establish the appliances’ current condition and produce a new gas safety record. This is different from recovering a copy, so don’t assume that a missing certificate alone proves a new check is required. First try to trace the inspection. If you can’t verify it, consider arranging a fresh check.
A duplicate doesn’t renew an expired check or change the inspection date. For example, if a copy shows that the inspection took place several months ago, it still records that earlier inspection. It doesn’t become a record of a more recent check.
If you’re working out how to get a replacement gas safety certificate, start with the records you have and confirm the inspection date and issuer. Then decide whether you’re requesting a copy of a traceable inspection or need a new check because the earlier one can’t be established.
How to get a replacement gas safety certificate: follow these steps
Work through these steps before booking another inspection. They’ll help you establish whether you can request a copy of an existing gas safety record or need a new check.
- 1. Search the property’s records. Check email inboxes, landlord portals, letting-agent files, invoices and maintenance records. Search by the property address and terms such as “CP12” or “gas safety record”.
- 2. Identify who carried out the inspection. Look for the engineer’s or business’s name on an invoice, booking confirmation or previous record. If a letting agent arranged the visit, ask them for the issuer’s details.
- 3. Request a copy from the issuer. The original engineer or business is the most direct source for an existing record. They can provide a copy if they’re able to locate it in their records.
- 4. Check the document when it arrives. Confirm that it relates to the right property, then review its inspection date, appliance details and recorded findings. A copy records the original inspection; it doesn’t update it.
What information should you provide when requesting a copy?
Give the issuer the full property address and the name used when the inspection was booked. Add the approximate inspection date and an invoice or booking reference, if you have one. These details can help identify the correct record. Ask for a copy showing the property details, inspection date and recorded findings, then compare these with your own records.
What if you cannot find the original engineer or company?
Look through old invoices, emails, property-management records and landlord communications for the issuer’s details. Your letting agent may also have paperwork from the booking. If you can’t identify the issuer or the record can’t be located, you may need a fresh check to establish the property’s current gas safety status. For guidance on landlord duties, see the HSE’s Landlords' legal responsibilities.
That’s the practical distinction behind how to get a replacement gas safety certificate: trace the issuer and request a copy if the original record can be found, but don’t treat an unlocated record as proof that a check is current. If you’re in London and need a fresh inspection, Everything Heating Ltd provides Gas Safety Certificates (CP12).
Replacement copy or fresh inspection: how to decide what your property needs
Choose your next step based on what you can verify, not simply on whether the paper copy is missing. A duplicate confirms what an earlier inspection recorded. A new inspection provides a current check and record.
| What you know | Practical next step |
|---|---|
| The inspection is traceable and the check is still relevant | Request the record from its issuer, then check the address, inspection date and findings. |
| You can’t establish whether the inspection took place or the issuer can’t find the record | Consider arranging a new inspection to create a clear record of the property’s current condition. |
| The check is due, or you’re unsure of its status | Verify the date and status using the record or reliable property-maintenance information. If you can’t establish that the check is current, arrange a new check. |
Does a replacement certificate make an old inspection current?
No. A replacement is a copy of the original gas safety record. It doesn’t involve a new inspection, change the date or update the findings. Check the inspection date and recorded outcome on the document, rather than relying on memory or the date you received the copy.
In England, landlords must arrange a gas safety check every 12 months. HSE guidance also says tenants must receive a copy of the record within 28 days of the check, and new tenants must receive it before moving in. The HSE guidance for landlords sets out these duties. Rules can differ across UK nations, so check the guidance that applies to the property. This is general information, not legal advice.
What should tenants do if they cannot find the record?
Ask the landlord or managing agent in writing for the current gas safety record. Keep the request factual: include the property address and ask for a copy of the record for the latest check. Save your message and any reply with your tenancy documents. If the landlord can’t provide the record, ask whether the original issuer can supply a copy or whether a new inspection is being arranged.
For landlords, deciding how to get a replacement gas safety certificate comes down to whether the existing inspection can be verified and its status is clear. Request a copy when the inspection can be traced. If the record is unavailable or you can’t establish that the check is current, a new inspection may provide a clearer basis for your property records and tenant communication.
How to check and store a gas safety record once you have it
Once you’ve received the gas safety record, check it before filing it away. A clear, accurate copy makes it easier to manage property maintenance and share the right information with tenants. It also gives you useful details to refer to if you need to contact the issuing business later.
Which details should you check on the certificate?
Compare the record with the property and inspection you expected. Check that it includes:
- Property address: Make sure it identifies the correct home or rental property.
- Inspection date: Note when the check took place. A copy doesn’t change this date.
- Appliance information: Check that the listed gas appliances match those covered by the inspection.
- Recorded outcome: Read the findings and any notes or actions recorded by the engineer.
If an address, appliance detail or finding looks wrong or unclear, contact the issuing engineer or business to discuss the record. Keep a note of who you spoke to and any correction or explanation they provide. For more background on the checks themselves, read a guide to what a CP12 inspection covers.
How should landlords organise gas safety documents?
Store the record with the property’s other maintenance and compliance paperwork. Keep a digital copy in a secure, organised folder, or file a paper copy where it’s easy to find. If you use both, make sure they match.
Use a file name that identifies the property and inspection date, such as Flat 2, High Street, gas safety record, 14 May 2026. Add the issuing engineer or business to your maintenance log, along with any invoice or booking reference. These details can make it easier to trace the record if you need another copy.
For landlords in England, HSE guidance says tenants must receive a copy of the gas safety record within 28 days of the check, and new tenants must receive one before moving in. Follow the rules that apply to your property and keep the record with its maintenance history. See the HSE guidance for landlords for current requirements.
Good organisation also helps if you later need to understand how to get a replacement gas safety certificate: you’ll have the address, inspection date and issuer details to hand. If you need a new CP12 inspection in London, arrange a Gas Safety Certificate with Everything Heating Ltd.
Need a new gas safety certificate in London? Arrange the next step
Your next step depends on what you can establish. If the original inspection is traceable, request a copy from the engineer or business that issued it, then check the record’s date and details. If the record can’t be found, or you can’t tell whether the check is current, consider arranging a new inspection. A duplicate reproduces an earlier record; it doesn’t replace a fresh check.
When arranging a new CP12 inspection makes sense
A new CP12 inspection may be the practical route if the original record can’t be located or the property needs a current check. A Gas Safe registered engineer carries out the inspection and records the checks completed and the findings. This gives you a clear document for the property’s records and for sharing with tenants where required.
Arranging an inspection is one part of managing landlord responsibilities. You’ll still need to keep the record organised and meet any separate duties that apply to your property and tenancy. Check current official guidance for the rules relevant to your location.

Frequently Asked Questions
Can I get a replacement gas safety certificate if I have lost the original?
Yes. Start by contacting the engineer or business that carried out the inspection and request a copy of its record. Provide the property address, approximate inspection date and any booking details you have. The issuer may be able to locate it in their records. If they can't, don't assume a duplicate is available. Consider arranging a new inspection and check the landlord requirements that apply to your property.
Who can provide a copy of a gas safety certificate?
The engineer or business that completed the original inspection is the most direct source for its record. Your landlord or managing agent may also have a copy in the property files. Provide details that help identify the inspection, such as the address and approximate date. If you can't trace the issuer or they can't find the document, consider whether a new gas safety check is needed to establish the property's current status.
Do I need a new gas safety check if my certificate is missing?
Not automatically. First try to recover the original inspection record and check its date and details. A duplicate documents the earlier inspection; it doesn't create a new record or change the inspection date. If you can't find a reliable record, or establish that a check is due, arranging a fresh inspection may be the clearest next step. Keep the new record with the property's maintenance documents.
Does a replacement gas safety certificate change its expiry date?
No. A copy of an existing gas safety record doesn't change when the inspection took place or make that inspection more recent. Check the inspection date and recorded findings on the document. Then use current official guidance to confirm the requirements that apply to your property and circumstances. Landlords shouldn't rely on receiving a replacement copy as proof that their gas safety duties have been met.
Can a tenant ask their landlord for a gas safety certificate?
Yes. A tenant can ask the landlord or managing agent for the relevant gas safety record. Make the request in writing, include the property address and keep a copy of your message and any response. Applicable duties and deadlines depend on the property's location and circumstances, so check current official guidance, particularly for properties outside England. A missing document alone doesn't confirm whether an inspection took place.
What information do I need to request a replacement CP12?
Provide the full property address, the name used when booking the inspection and an approximate inspection date. An invoice, email, service record or booking reference may help the issuer find the right document. Ask for a copy showing the property and inspection details, then check these when it arrives. If you can't identify the original issuer, look through property and maintenance records before deciding whether to arrange a new check.
Can Everything Heating Ltd provide a gas safety certificate in London?
Yes. Everything Heating Ltd is a Gas Safe registered business serving London and provides Gas Safety Certificates (CP12). If you need a new inspection because the earlier record can't be located or a check is due, arrange a Gas Safety Certificate in London. A new inspection is different from obtaining a duplicate of a record created by another engineer, and doesn't retrieve that earlier record.
