Homeowners, buyers, landlords and conveyancing enquiries
Match the gas evidence to the sale, occupancy and actual request
An owner-occupied sale, a buyer-requested specialist inspection and a tenanted property do not create the same gas-safety route. Send the postcode, occupancy, fuel, appliances, documents already held and the exact question raised by the buyer, surveyor, lender or conveyancer.
The direct answer
The sale itself is only one part of the decision
Start with the seller's paperwork list
Current GOV.UK guidance identifies the EPC as required sale paperwork and lists previous gas checks as supporting evidence a seller may already hold. Ask the conveyancer what is required for this transaction.
Define the specialist inspection
Record who requested it, the wording used, every appliance and flue, who pays, access arrangements and who receives the report. Do not substitute an unrelated service invoice.
Keep landlord duties running
The existing dutyholder must continue to meet the applicable rented-property gas duties while the tenancy and responsibility remain. The transaction team should document the handover.
State the occupancy history
Send the last landlord record, tenancy end date, appliance changes, known defects and future use. A previous record does not describe later alterations or guarantee current condition.
Do not merge unlike documents
Five records answer five different questions
| Document or visit | What it is for | Who should clarify it | What it does not automatically include |
|---|---|---|---|
| Energy Performance Certificate | Reports the property's energy efficiency and is required for most home sales under the relevant sale rules. | Accredited assessor, estate agent or conveyancer. | A gas safety inspection, boiler service or repair. |
| Gas safety check or report | Records findings from the gas-safety scope agreed for the property and appliances. | Gas Safe registered engineer with the correct categories. | A guaranteed pass, repair, service or future-condition warranty. |
| Boiler or appliance service | Maintenance undertaken to the manufacturer's requirements for the specified appliance. | Competent Gas Safe registered engineer. | A whole-property gas report or every buyer enquiry. |
| Landlord gas safety record | Records the annual check required for relevant landlord-provided appliances and flues. | Current landlord or responsible agent and qualified engineer. | Universal proof for every owner-occupied sale or later property change. |
| Installation and compliance documents | Evidence about particular installation work, commissioning or building-regulation notification. | Installer, scheme provider, local authority or conveyancer as applicable. | Current safety findings for all gas appliances and flues. |
Prepare before requesting attendance
Gather the facts once and give each professional what they need
Address, tenure and occupancy
Provide the complete postcode, England, Wales, Scotland or Northern Ireland, freehold or leasehold status, owner-occupied, vacant or tenanted use and any communal plant.
Use the exact wording
Forward the buyer, surveyor, lender or conveyancer question. State whether they want existing paperwork, a gas safety inspection, appliance service, repair or another output.
List the fuel and equipment
Identify natural gas or LPG, every boiler, fire, cooker, hob, heater and relevant flue, their locations and any shared, inaccessible or decommissioned equipment.
Send dates and readable copies
Include recent records, service reports, repair invoices, installation documents and known defect notices. Do not rename one document to fit another request.
Plan the appointment around the sale
State who has keys, whether the property is occupied, notice requirements, alarm or concierge arrangements, parking and every area the engineer must reach.
Use the real transaction date
Give the requested response date and the planned exchange or completion stage, but allow time for findings, repairs or return attendance without promising an instant outcome.
Keep the sale moving with evidence
Use the right action at each stage
Build the property document file
Check the EPC, title and installation paperwork and gather genuine gas records already held. Ask the estate agent or conveyancer what is missing.
Answer the question actually raised
Do not order a generic certificate before reading the buyer's or solicitor's wording. Clarify whether existing evidence is enough or specialist attendance is requested.
Agree the defined gas scope
Confirm the appliances, flues, fuel, access, requested report, recipient and separate service or repair requirements in the quotation.
Keep the report and follow-up together
Give the relevant findings to the transaction professional. If work follows, retain quotations, authorisation, invoices and updated evidence without hiding the original result.
Selling a tenanted property
A change of owner does not erase the current landlord history
For relevant rented property in Great Britain, the landlord must arrange the annual gas safety check for landlord-provided appliances and flues, retain the record and provide the latest record to tenants within the applicable timescale. The seller remains responsible while the duty applies to them.
The sale team should identify the tenancy, current dutyholder, last check date, next due point, open defect or repair work, record supplied to the tenant and the date on which responsibility changes. Northern Ireland uses a separate regulatory framework, so the property location must be declared.
Findings are not a sales promise
Separate inspection, service, defects and remedial work
A gas record can contain an unsafe or unsatisfactory finding
Do not advertise a guaranteed certificate, guaranteed pass or fixed repair outcome before the engineer has inspected the actual installation. The report should reflect the evidence found on the day.
If equipment is unsafe, it must not be used and the engineer's safety advice must be followed. Fault diagnosis, parts, repairs, replacement and return attendance can require a separate quotation and authorisation.
A seller should keep the original report with the later repair or service evidence so the buyer and conveyancer can see the sequence rather than an incomplete final document.
Choose the correct trade
The engineer's registration must match the property and work
Domestic appliances and flues
List every appliance rather than booking from the boiler alone. The engineer must hold the applicable domestic natural-gas categories for the work.
Fuel and installation type matter
Declare cylinders, bulk tank, caravan, park home or off-grid arrangement. LPG competence and the property or appliance category must be checked before attendance.
Do not hide commercial equipment
Identify shops, catering appliances, communal plant, workshops or business areas so domestic and commercial scopes are not confused.
Route diagnosis separately
Send fault codes, warning labels, photos, recent work and disconnected appliances. A home-sale inspection is not automatic authorisation for repair or installation work.
Request a complete quotation
Price the property, scope and output — not the word "certificate"
A reliable quotation depends on the postcode, occupancy, fuel, appliance and flue count, access, requested output and any separate service or repair work. A single headline price cannot describe every sale enquiry.
Ask the written quotation to state what will be inspected, the document provided, VAT and travel treatment, cancellation terms, exclusions and how findings or follow-up work will be handled.
Postcode-qualified coverage

Regular work covers London, Essex and Kent. Hertfordshire, Surrey, Buckinghamshire, Berkshire and Sussex can be considered when the right trade is available. Other areas are considered by request after the postcode, property use, fuel, appliances, access and competence have been checked.
