LPG supplier emergency route, evacuation and safe follow-up
Leave danger first—then call the LPG supplier from a safe place
If there is fire, an uncontrolled release, immediate danger or any doubt, evacuate and call 999, saying that LPG cylinders or a tank are present. For a suspected LPG escape without fire, HSE directs you to the LPG supplier—not Upkeepone's routine enquiry line.
The direct decision route
Use the incident, fuel and supplier—not a generic gas-service number
A smell, hissing, visible frost at a leak point, damaged pipe or detector warning can indicate danger. Do not stay to prove the source. Choose the safest route below from a place away from the suspected release.
Evacuate and call 999
Tell the operator that LPG cylinders or a bulk tank are present, give the exact location and keep people away. Do not approach a vessel involved in fire or attempt firefighting that puts anyone at risk.
Call the LPG supplier
Use the emergency number displayed on the tank, cylinder, delivery paperwork or supply agreement. Follow the supplier's instructions. Do not use Upkeepone's routine line to report the live incident.
Go outside and get medical advice
CO has no smell. Stop using a suspect appliance only if this can be done safely, go into fresh air, use NHS 111 for possible symptoms and call 999 for severe symptoms or a life-threatening emergency.
Do not call or search websites beside a suspected release. Move to a safe place first. If delay, uncertainty or conditions are making the situation more dangerous, call 999.
Avoid ignition and exposure
Do not turn a leak investigation into a fire, explosion or cold-burn injury
Do not operate switches or equipment
Do not switch lights, extraction, appliances, security systems or electrical equipment on or off in the affected area. Do not smoke, vape, strike a match, use a flame, start an engine or make a phone call beside the leak.
Do not enter to check where vapour collected
LPG vapour is heavier than air and can gather in basements, cellars, pits, drains and low points. Keep out, prevent others entering and tell the supplier or fire service about these spaces.
Do not touch a frosted leak or saturated clothing
Escaping liquid LPG can cause severe cold burns. Stay clear, avoid contact and tell emergency responders about any exposure. Do not handle a damaged connection or frozen component to see whether it is loose.
Do not approach an unfamiliar tank or cylinder bank
Only isolate an accessible user control where the emergency plan or supplier instructions assign that action, the control is known and it is safe to approach. Never force, adjust, dismantle or repeatedly reset equipment.
LPG and natural gas use different escape routes
The National Gas Emergency Service is not a substitute for the LPG supplier
Identify the fuel without delaying safety action
HSE's workplace guidance separates the contacts: a suspected natural-gas leak uses the National Gas Emergency Service on 0800 111 999, while a suspected LPG leak goes to the LPG supplier. An LPG property may have cylinders, a cylinder bank or a bulk tank rather than a mains-gas meter.
Use the branding and emergency number on the LPG tank or cylinders, the delivery account, landlord information or site emergency plan. Liquid Gas UK also provides a supplier search, but a directory search must not delay evacuation or a 999 call.
If the fuel cannot be identified and there is immediate danger, fire, an uncontrolled release or uncertainty that makes staying unsafe, leave and call 999. Tell the operator exactly what you can see and that the fuel is uncertain.
Apply the emergency plan to the real setting
A home, cylinder cage, catering unit and bulk-tank site do not have the same safe approach
Get occupants outside and use the supplier route
Account for children, older people, tenants, visitors and anyone needing assistance. Do not re-enter for belongings or to operate a valve. Landlords and managers should make the supplier number and safe evacuation arrangements available before an incident.
Small spaces can fill quickly
Stop use and get everyone into fresh air. Follow the installed cylinder or tank instructions and the site or marina plan. Do not assume a habitation certificate, detector or recently passed inspection makes a current smell or alarm safe.
Protect staff, customers and neighbouring traders
Stop trading, isolate the public from the unit and tell the organiser or site controller. Cylinders, manifolds, pigtails and cooking appliances can place the source outside or inside the unit; do not move equipment to keep trading.
Use trained roles and the written plan
Raise the site alarm, control access and vehicles, account for people and call the supplier. Tell responders about tanks, cylinders, underground or low spaces, process plant and any known isolation. Leave fire near a tank to the fire service unless the plan and conditions make another action demonstrably safe.
Call from a safe location
Give the supplier or 999 enough information to find and control the incident
Exact address and access
Give the postcode, site name, entrance, gate or unit number, landmarks and a safe rendezvous point. Explain if roads, yards or access routes may bring responders towards the release.
Tank, cylinders, pipework or appliance
Describe what you can observe from safety: smell, sound, frost, damage, detector, fire, vehicle impact or failed equipment. State propane, butane or unknown, and the supplier if known.
People exposed or unaccounted for
Report injuries, breathing problems, cold burns, suspected CO symptoms, vulnerable occupants and anyone who may remain inside. Follow the call handler's medical and evacuation instructions.
Isolation and changing conditions
Say whether a known valve was closed by an authorised person, whether the release continues, and whether wind, fire, noise or vessel condition is changing. Do not approach again to obtain an answer.
Carbon monoxide is a different hazard
An LPG smell and a CO alarm need separate information and medical decisions
CO has no smell, colour or taste
Possible symptoms include headache, dizziness, nausea, weakness, tiredness, confusion, chest or muscle pain and shortness of breath. Symptoms may improve outside and return in the affected building. Do not dismiss an alarm because no LPG odour is present.
NHS guidance says to stop using the suspected appliance if possible, go outside and obtain medical advice before returning. Contact NHS 111 if you think you may have symptoms. Call 999 or go to A&E for severe warning signs such as difficulty breathing, sudden confusion, loss of consciousness, weakness or chest or muscle pain.
The appliance and installation still need the appropriate competent investigation before use resumes. A supplier attendance, medical assessment, gas-safety check, appliance service and CO-source investigation are different scopes; confirm what was and was not completed.
A stopped smell is not clearance to restart
Keep the supply off until the leak and restoration route are resolved
HSE says not to turn a gas supply back on until a leak has been dealt with by a competent person. The supplier may control its tank, cylinders, emergency equipment or upstream supply while customer-owned pipework and appliances require a separate competent contractor.
Ask what was isolated, what was tested, what fault was found, what temporary or permanent repair was made, whether affected sections were tightness tested and purged, whether regulator and safety devices were checked, which appliances were commissioned and what remains unsafe or outside scope.
Do not relight every appliance as a test. Do not assume a supplier visit produces a landlord record, catering certificate, commercial inspection or whole-installation approval.
Non-emergency follow-up only
Send the incident record after the supplier or emergency service controls the danger
Upkeepone is not an emergency-response service. Once the immediate risk is controlled, the details below help distinguish leak investigation, pipework repair, appliance work, tightness testing, commissioning and certification before a normal appointment is considered.
Choose the next scope deliberately
Emergency control, diagnosis, repair, testing and certification are not interchangeable
Locate the affected component or section
The competent person may need controlled isolation, safe detection methods, pressure information and access. A reported smell does not identify whether the source is supplier equipment, service pipework, installation pipework, a connection or an appliance.
Define ownership and the remedial item
Supplier-owned equipment can need the supplier. Customer pipework, regulators, appliances or installations may need an LPG-qualified trade matched to the setting. Parts replacement alone does not prove the system is ready for use.
Record the safe restoration basis
Tightness testing, purging, operating-pressure checks, safety-device checks and appliance commissioning use installation-specific procedures. Ask for the section, standard, result, limitations and restoration status in writing.
Request the correct document separately
A landlord record, static-caravan check, mobile-catering certificate, commercial inspection or service record has its own scope. An emergency attendance or isolated leak repair does not automatically create every document.
Continue after immediate danger is controlled
Choose the closest non-emergency LPG route
Current official routes

NHS: carbon-monoxide poisoningSymptoms, leaving the affected building, NHS 111 and the warning signs that require 999 or A&E.
Prepare before another incident
Display the supplier number and train people to leave, report and prevent restart
Homes, landlords, park operators and businesses should keep the current LPG supplier and emergency number with the installation information. Workplaces need a site-specific emergency plan covering alarm, evacuation, assembly, access control, trained isolation roles, 999 and supplier calls, information for responders and authority to keep equipment out of use.
Review the plan when the supplier, tank, cylinder bank, pipework, appliances, occupancy, trading layout, vehicle route or responsible people change. A number stored only on one person's phone is not a resilient emergency arrangement.
Check current feedback before sending the follow-up scope
Only after the LPG supplier or emergency service has controlled the immediate risk, read Upkeepone's live Google results in their original context. Then send the postcode, fuel and supplier, cylinders or tank, affected area, supplier attendance or incident reference, isolation state, known damage, previous records, appliances, access limits and the exact inspection, repair, test or paperwork required.

Non-emergency follow-up
Contact Upkeepone only after the immediate LPG risk is controlled
Upkeepone can review a normal follow-up enquiry and check whether the requested investigation, repair, testing, commissioning or certificate scope can be routed to an appropriate LPG trade. An enquiry does not confirm emergency attendance, availability, diagnosis, price, supplier responsibility or permission to restore use.
If LPG is currently escaping, there is fire, immediate danger or doubt, use the LPG supplier or 999 route above—not these routine enquiry contacts.
