What a CP12 actually covers

A gas safety record is an appliance-by-appliance check, not a single tick box. Every gas appliance the landlord owns in the property is inspected, along with the pipework feeding it and the flue taking combustion products away. If a property has a boiler, a gas hob and a gas fire, all three appear on the certificate.

  • Gas tightness test on the installation pipework
  • Operating pressure and burner performance at each appliance
  • Flue flow and spillage testing
  • Ventilation checked against the appliance requirements
  • Visible condition of pipework and appliance safety devices

What the regulations require of you

Regulations put the obligation on the landlord, and enforcement follows the landlord rather than the engineer or the agent. Holding a current record, issuing it to tenants and being able to produce the last two years of records is the practical test of compliance.

  • Annual cycle, dated from the check rather than the tenancy
  • Tenant copy issued in writing, digital is acceptable
  • Two years of records retained and produceable on request
  • Duty stays with the landlord even where an agent books the visit

Failures, warning notices and next steps

Where a defect is found the appliance is categorised by severity, the tenant is told what it means in plain terms and a warning notice is left. Turning the appliance off is done with permission, and the property is never left without an explanation of what has happened and what fixes it.

  • Defect classified and explained on the day
  • Warning notice left with the tenant and copied to you
  • Appliance made safe with permission
  • Quote for the remedial work provided in writing

Getting access without a fight

Access is the part that costs landlords money, not the check itself. Giving proper written notice, offering a time window rather than a single moment, and letting tenants pick from two or three slots removes most refusals before they happen.

  • Notes kept of every access attempt
  • Tenant told what the engineer needs to reach
  • Cupboards and meter boxes cleared in advance
  • Repeat visits agreed rather than assumed

Records, copies and evidence

The evidence that matters is the certificate, proof the tenant received it, and the records for the previous two years. Keep those three and most disputes about compliance end quickly.

  • Certificates filed by address, not by date received
  • Expiry dates in a shared calendar with a reminder
  • Proof of issue to the tenant kept with the record
  • Warning notices and remedial invoices stored alongside

Bolton FAQs — landlord gas safety certificate

How often does a landlord gas safety check need doing?+

Every twelve months, on every gas appliance and flue the landlord owns. The clock runs from the date of the check rather than the start of the tenancy.

What if the tenant will not let us in?+

Give written notice with a choice of dates, keep a record of every attempt and offer a time window rather than a fixed minute. Most refusals are really diary problems. We are happy to work around evenings and key safes.

How long does a visit take?+

A single boiler is usually straightforward. Add a gas fire or a hob and the visit grows, because each appliance is tested and written up separately.

Can you do several properties in one booking?+

Yes. Send the addresses and expiry dates and we will plan them in geographic order and return the certificates as one batch.

Do you certify gas fires and hobs as well as boilers?+

Yes, every landlord-owned gas appliance in the property is tested and appears on the record with its own result.

Do you cover the whole of Bolton?+

Yes, every BL1 street in and around Bolton, including the properties out toward A58 and A6. Bolton Council area landlords and agents are booked on the same terms.
