BUSHEY · GAS LEAK INVESTIGATION
Two leaks in existing pipework

LANDLORD GAS SAFETY · MILL HILL
Separate safety records from wider property checks
For a Mill Hill rental, TNG Services can discuss the landlord gas safety check and record you need. If you also want electrical inspection, cylinder maintenance or boiler servicing, list those requests so the appropriate scopes can be agreed.
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
Additional systems need their own scope
A gas safety record does not replace an Electrical Installation Condition Report. Unvented cylinder maintenance is also a separate request, even when a boiler and cylinder operate as part of the same hot water system.
Explain which services you need before booking. Visual observations during one visit should not be mistaken for a completed inspection or test of another system.
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.

Does a CP12 include an EICR?
No. They are separate scopes. Request any electrical inspection explicitly and confirm what is being arranged.
What should I send with the enquiry?
Send the property postcode in Mill Hill, 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.
