What Is a Gas Safety Certificate?

A Gas Safety Certificate, officially known as a CP12, is a legal document confirming that all gas appliances, fittings, and flues in a property have been inspected and are safe to use.

Under the Gas Safety (Installation and Use) Regulations 1998, all landlords in England are legally required to have a gas safety check carried out by a Gas Safe registered engineer every 12 months. Failure to comply can result in fines of up to £6,000 and, in serious cases, a custodial sentence.

At DRMB Plumbing & Heating, our Gas Safe registered engineers carry out thorough, professional gas safety inspections quickly and efficiently, issuing your CP12 certificate after the check. Landlords managing multiple rental properties should also see our dedicated landlord gas safety service for multi-property discounts and annual reminders. Bromley-specific page: CP12 Bromley from £90 (CP12 + boiler service combined £160).

If your gas safety check reveals a boiler fault or an appliance that needs replacing, we can help with that too. We offer fast boiler repairs, new boiler installations, dedicated boiler installation Bromley and boiler installation Beckenham pages, and an annual boiler service in Bromley from £90.

Simple from start to finish

What happens on a gas safety check

Four steps, in plain English. The checks themselves are listed below.

  1. Step 1: Book the check

    Tell us the address, how many gas appliances and when the tenant can give access. Day and price confirmed first.

  2. Step 2: We visit

    A Gas Safe registered engineer attends at the agreed time. Allow 45 to 60 minutes for two appliances.

  3. Step 3: We test

    Tightness test on the pipework, gas pressure, flue and ventilation checks, and every appliance inspected and tested.

  4. Step 4: Certificate emailed

    Signed by the engineer and emailed to you after the check. Valid for 12 months, and we remind you when it is due.

Your Legal Obligations as a Landlord

Don't risk fines, invalidated insurance, or prosecution. Stay compliant.

Annual Requirement

By law, every landlord must have a Gas Safety Record (CP12) renewed annually for every rental property with gas appliances.

Fines Up to £6,000

Non-compliance with Gas Safety Regulations can result in unlimited fines and up to 6 months imprisonment. Don't take the risk.

Give Tenants a Copy

You must provide tenants with a copy of the CP12 certificate within 28 days of the check, or before they move in for new tenants.

Keep Records for 2 Years

Landlords must retain gas safety records for a minimum of 2 years. We issue digital copies so you always have a record on file.

What Landlords Say About Us

★★★★★
"I highly recommend Michael and his team. When my boiler broke while I was travelling and had tenants in, he was there to put a new one in and recommended a reasonably priced one. Each year he reminds me when it is time for a service and when things have gone wrong he is at the door quickly and with a friendly but professional manner."
