LANDLORD GAS SAFETY · HARPENDEN
Give the annual check a clear starting point
For a landlord gas safety check in Harpenden, start with the previous record, appliance details and the due date. TNG Services can discuss the visit and any separately requested boiler maintenance, with existing faults identified before work begins.
01 · PREPARE
Confirm the appliances
Share the property address, appliance list, previous record and access arrangements.
02 · CHECK
Complete the safety checks
The relevant appliances and flues are assessed by an appropriately qualified Gas Safe registered engineer.
03 · FOLLOW UP
Act on the findings
Keep the record, provide the tenant’s copy and arrange any necessary remedial work.
Showing the single result
The previous record provides useful context
Check the appliance entries and any observations on the earlier record. If work was recommended, gather the follow-up documents rather than assuming a later visit addressed every item.
An engineer assessing the property needs to understand known concerns and relevant changes. Share the records available, including information about replacements or remedial work since the last check.
Three different requests, clearly identified
Why the wider installation matters
These examples come from gas leak investigation and boiler service visits. They illustrate defects found during TNG’s work; they are not presented as completed landlord CP12 inspections.
STEVENAGE · AT RISK INSTALLATION
Flue and pipework defects
An inspection found incorrect flue fall, inadequate support and securing, and an unsleeved gas pipe wall entry. The installation was classified At Risk; the article documents the findings rather than completed repairs.

BOREHAMWOOD · BOILER SERVICE
Satisfactory combustion was not the whole picture
The boiler operated with satisfactory combustion readings, but the visit identified a flue defect and gas-pressure concerns. Separate cylinder and visual electrical observations were also recorded.

What if I cannot find the previous record?
Say so when enquiring and provide the appliance details and any available paperwork. Do not invent a previous check date.
What should I send with the enquiry?
Send the property postcode in Harpenden, the gas appliance list, previous record and due date if known. Explain access arrangements and any existing faults or notices. Avoid unnecessary tenant personal information.
Does a record guarantee that no faults were found?
No. The record contains the completed check results. Read the findings and arrange any required remedial action; an unsafe appliance must not be used.
Keep the dates and follow-up records together
Landlord checks are required annually. Existing tenants need a copy of the record within 28 days; new tenants need it before moving in. Retain records for at least two years, with additional retention conditions when using early-check flexibility.
