Showing 46 of 46
Food hygiene certificate (Level 1, 2 or 3)
No legal expiry
A UK food hygiene certificate has no legal expiry date, and food handlers do not legally need a formal certificate. The law requires training or supervision suited to each person’s work. Councils such as East Devon recommend refresher training at least once every three years.
Emergency lighting testing (BS 5266 guidance)
Monthly, plus a yearly full test
Emergency lighting has no legal expiry, but it must be kept in efficient working order. Government fire safety guidance, which refers to BS 5266, suggests a short monthly function test of every light and a yearly test for its full rated duration, carried out by a competent person.
Employers’ liability insurance certificate
As long as the policy
An employers’ liability certificate is valid for the policy period shown on it, commonly 12 months. Most employers in Great Britain must hold at least £5 million of cover from their first employee, display the current certificate where staff can read it, and renew before the end date.
Fire alarm servicing (BS 5839-1 guidance)
Every 6 months (guidance)
No law sets a fire alarm service date, but the system must be kept in efficient working order. Government fire safety guidance, which points to BS 5839-1, says to test the alarm weekly and have a competent person test and maintain it every six months.
Fire extinguisher servicing (BS 5306-3 guidance)
Every 12 months (guidance)
No law sets a fire extinguisher service date, but extinguishers must be kept in efficient working order. Government fire safety guidance says to check them monthly and have a competent person maintain them every year, and points to BS 5306-3 for maintenance.
Fire risk assessment (FRA)
No fixed expiry
A fire risk assessment has no legal expiry date in England. The responsible person must review it regularly, and whenever it may no longer be valid or the premises change significantly. A yearly review is common practice, not law. Since October 2023 it must be recorded in full.
First Aid at Work (FAW) and Emergency First Aid at Work (EFAW) certificate
3 years
HSE guidance says FAW, EFAW and other workplace first-aid certificates are valid for three years from the date the course was completed. After the expiry date the person is no longer considered competent to act as a workplace first-aider until they requalify.
Forklift (lift truck) training certificate
No legal expiry
There is no such thing as a forklift licence in the UK, and training certificates have no legal expiry. Employers must keep operators competent. HSE says you may choose automatic refresher training or a retest after a set period, for example 3 to 5 years, while still monitoring performance.
Legionella risk assessment
No fixed expiry
A legionella risk assessment has no expiry date. HSE says the law does not require an annual or two-yearly review, only a periodic one and a fresh look when anything changes. Landlords must assess the risk, but a legionella test or certificate is not required.
LOLER thorough examination of lifting equipment
6 or 12 months
LOLER 1998 requires a thorough examination at least every 6 months for equipment that lifts people and for lifting accessories, and at least every 12 months for other lifting equipment, unless a written examination scheme sets different intervals. A “LOLER certificate” is the report from that examination.
Permit to work
For the stated period only
A permit to work is a written authorisation for a specific high-risk job, such as hot work, entry into vessels or work needing isolation. It is valid only for the time written on it, is amended or cancelled if the work changes, and is closed out when finished.
Portable appliance testing (PAT)
No fixed legal interval
No law sets a PAT testing interval, and HSE says annual testing is not a legal requirement. The frequency depends on the equipment and where it is used. For kettles and other earthed kit in low-risk workplaces, HSE suggests a combined test every 1 to 2 years.
PUWER inspection of work equipment
At suitable intervals
PUWER regulation 6 sets no fixed period. Equipment whose safety depends on installation must be inspected after installation, and equipment exposed to conditions that can cause dangerous deterioration must be inspected at suitable intervals set by risk, with every result recorded until the next inspection.
Goods vehicle operator licence (O licence)
Continuation every 5 years
A goods vehicle operator licence does not have a simple expiry date, but you must pay a continuation fee every five years to keep it active. GOV.UK lists the continuation fee as £401.
ISO 9001 certificate (accredited management system certification)
3 years
An accredited ISO 9001 certificate is issued for a three-year cycle. Surveillance audits run at least once a calendar year, the first within 12 months of the certification decision, and the recertification audit and decision must be completed before the certificate expires.
NMC registration and revalidation
Every 3 years
Nurses, midwives and nursing associates must revalidate with the NMC every three years and pay the annual fee every year. The revalidation application is due on the first day of the month in which registration expires. Miss it and registration lapses, so you cannot practise.
Security Industry Authority (SIA) licence
3 years
SIA licences last three years, except the vehicle immobiliser licence (Northern Ireland only), which lasts one year. They do not renew automatically. You can apply up to four months before expiry, and any time left is added to the new licence. Working without a required licence is a criminal offence.
Electrical Installation Condition Report (EICR)
Up to 5 years
In England, a rented home's electrics must be inspected and tested at least every 5 years, so an EICR lasts up to 5 years. If the report sets an earlier date, that date applies instead. Tenants must get a copy within 28 days.
Energy Performance Certificate (EPC)
10 years
An Energy Performance Certificate is valid for 10 years. You need a valid one whenever you sell or let a property, and must commission it before marketing starts. If it expires during a tenancy, you need a new one before you next sell or let.
HMO licence (house in multiple occupation)
Up to 5 years
An HMO licence lasts for the period the council sets, up to a maximum of 5 years. It cannot be transferred and it ends if the holder dies. Apply to renew before it runs out: a valid application protects you while the council decides.
Landlord gas safety record (gas safety certificate, CP12)
12 months
A landlord gas safety record, often called a CP12, lasts 12 months. Each gas appliance and flue a landlord provides must be checked by a Gas Safe registered engineer at least every 12 months. A check done in the 2 months before the deadline keeps the original due date.
Smoke and carbon monoxide alarms in rented homes
On day one of each tenancy
Smoke and carbon monoxide alarms have no legal expiry date. In England, landlords must check they work on the day each new tenancy begins, and repair or replace any alarm reported faulty. Fire services advise testing smoke alarms monthly and replacing them every 10 years.
Digital tachograph driver card
5 years
A digital tachograph driver card expires five years after issue. Apply to renew at least 15 working days before the expiry date. A driver whose card has expired cannot drive a vehicle that is in scope of the drivers’ hours rules until the new card arrives.
Driver Certificate of Professional Competence (Driver CPC)
5 years
Driver CPC lasts five years. To keep driving a lorry, bus or coach professionally, you must complete 35 hours of periodic training before the deadline shown on your Driver CPC card. Driving professionally without it can mean a fine of up to £1,000.
DVLA driving licence check for employers
No legal interval
There is no fixed legal frequency. The employer checks online with the driver’s DVLA check code and the last 8 characters of their licence number; the code must be used within 21 days and works once. Many employers re-check at least annually, more often for higher-risk drivers.
Construction Skills Certification Scheme (CSCS) card
Usually 5 years
Most CSCS cards, including the Blue and Gold Skilled Worker, Manager and Supervisory cards, are valid for five years. The Labourer card lasts two years on first issue. Some cards last six months to three years and cannot be renewed. You can renew from six months before expiry.
CPCS card (Construction Plant Competence Scheme)
5 years (blue card)
A blue CPCS Competent Operator card is issued for five years. You can apply to renew from three months before expiry, with the CPCS CPD renewal, an HS&E test passed within two years and evidence of operating experience. Red Trained Operator cards are extended, not renewed.
Disclosure and Barring Service (DBS) check
No official expiry
A DBS certificate has no official expiry date. It is accurate only on the day it was issued, and the employer decides when a new check is needed. Many NHS organisations re-check every three years, or use the DBS Update Service for continuous status checks.
IPAF PAL card (Powered Access Licence) for MEWP operators
5 years
An IPAF PAL card is valid for five years. Renewal must be done before the expiry date, and from 1 January 2026 operators need at least 60 logbook entries over the five years to sit the renewal test. Miss either and you retake the full operator course.
NPORS operator card (CSCS-branded Trained and Competent Operator)
2 years (red) or 5 years (blue)
An NPORS CSCS-branded Trained Operator (red) card is valid for two years and can be extended once by 12 months if you are registered for an NVQ. The Competent Operator (blue) card, issued once the qualification is achieved, is valid for five years.
PASMA certificate and card (mobile access towers)
Usually 5 years
A PASMA certificate is valid until the expiry date printed on it, and PASMA describes five years as the usual period. To renew, you attend a course with a PASMA approved training centre, including a written and practical test, before the expiry date.
Right to work check and follow-up checks
When permission ends
A correct check on someone with a continuous right to work, such as a British or Irish citizen or a settled person, never needs repeating. For time-limited permission, do a follow-up check on or before the date it ends, or within six months where the check gives a six-month excuse.
SMSTS and SSSTS certificates (CITB Site Safety Plus)
5 years
CITB says SMSTS and SSSTS certification is valid for five years. To stay certified, site managers take the two-day SMSTS-R refresher and supervisors the one-day SSSTS-R refresher before the expiry date, or retake the full course.
Food handler card (food handler certificate)
Usually 2 to 3 years
It depends on the state. A California food handler card is valid for three years and is due within 30 days of hire. Texas certificates last two years unless the card shows another date. A first Washington food worker card lasts two years.
ServSafe Food Protection Manager Certification
5 years
The National Restaurant Association recognizes the ServSafe Food Protection Manager Certification for five years. ServSafe Food Handler, Alcohol and Allergens certificates are recognized for three years. State, local and employer requirements can differ, so check with your health department.
Boiler inspection and certificate of operation
Every 1 to 2 years, by state
Boiler inspection rules are set by each state. In the states we checked, high-pressure (power) boilers are inspected every 12 months. Low-pressure heating boilers are usually inspected every 12 or 24 months. A state or insurance company inspector does the inspection, and you post the certificate near the boiler.
CPR and Basic Life Support (BLS) certification
2 years
CPR and BLS certifications from the American Heart Association and the American Red Cross are valid for two years. AHA cards show a recommended renewal date two years after issue, through the end of that month. Employers and state rules can require more frequent training.
Fire extinguisher inspection, maintenance and hydrostatic testing
Monthly, plus yearly service
OSHA requires employers to visually inspect portable fire extinguishers monthly and give each one an annual maintenance check, with the date recorded. Stored-pressure dry chemical units also need emptying and maintenance every 6 years. Shells need hydrostatic testing every 5 or 12 years, depending on type.
Forklift (powered industrial truck) operator certification
3 years
Under OSHA’s powered industrial truck standard, each forklift operator’s performance must be evaluated at least once every three years. Refresher training is also required sooner after an accident or near miss, unsafe operation, a failed evaluation, a new truck type or changed workplace conditions.
OSHA Outreach 10-hour and 30-hour course completion card
No federal expiry
OSHA 10-hour and 30-hour course completion cards do not expire under the federal program, which is voluntary. Some states, cities and employers set their own rules. Nevada cards for entertainment and convention work expire after 5 years, and New York City site safety cards last 5 years.
Certificate of good standing (certificate of status or existence)
As recent as the requester needs
A certificate of good standing shows your entity’s status on the day the state issues it. Whoever asks for it decides how recent it must be. Florida requires one dated within 90 days to register a foreign company, and New York accepts one dated within one year.
Certificate of insurance (COI)
Until the policy expires
A certificate of insurance has no validity period of its own. It is a snapshot of the policies listed, and each line shows a policy effective and expiration date. Once a listed policy expires, renews or is canceled, ask for a new certificate. Many business policies run for 12 months.
Form W-9 (Request for Taxpayer Identification Number and Certification)
No expiration date
A Form W-9 has no expiration date. Get the current IRS form at irs.gov/forms-pubs/about-form-w-9 and collect it before you first pay a vendor. Request a new one when the vendor’s name, TIN or tax status changes, or after an IRS incorrect-TIN notice.
State annual report (LLC and corporation annual or biennial report)
Every 1 or 2 years, by a state deadline
It depends on the state. Florida annual reports are due between January 1 and May 1. Georgia’s are due by April 1, Delaware corporations’ by March 1, and Texas reports by May 15. New York corporations and LLCs, and California LLCs, file every two years.
DOT medical examiner’s certificate (DOT medical card)
Up to 24 months
A DOT medical examiner’s certificate is valid for up to 24 months. The examiner can certify you for less, for example to monitor high blood pressure, and some conditions need yearly exams. The exam must be done by an examiner on FMCSA’s National Registry.
Registered nurse (RN) license renewal
Usually every 2 years
Each state board of nursing sets its own RN license renewal cycle. California, Texas and Florida generally use two-year cycles, while New York registration renews every three years. New York and Texas say you cannot practice as a nurse while your license or registration is expired.
