Landlord Gas Safety Certificate (CP12)
Annual gas safety checks and certificates for landlords and letting agents, as required by law.

What it is
A Landlord Gas Safety Record, often called a CP12, confirms that the gas appliances, fittings and flues in a rented property have been checked by a Gas Safe registered engineer.
When you need it
Landlords must arrange a gas safety check every 12 months. A copy of the record must be given to existing tenants within 28 days of the check and to new tenants before they move in, and records must be kept for at least two years.
How we do it
We arrange a time that suits you and your tenants, check every gas appliance, fitting and flue in the property, and issue the safety record. If anything needs attention, we explain what is required and can carry out the work.
Gas Appliance Installation
Safe installation of gas cookers, hobs and fires, connected and tested by a Gas Safe registered engineer.

What it is
We connect and install gas appliances such as cookers, hobs and gas fires, and can install or reroute gas supply pipework where needed.
When you need it
Whenever you buy a new gas appliance, replace an old one or want to move one to a new position. By law, any work on gas appliances must be carried out by a Gas Safe registered engineer.
How we do it
We check the gas supply and ventilation, install the appliance in line with the manufacturer's instructions, test for gas tightness and safe operation, and show you how everything works.
Boiler Servicing & Repair
Annual boiler servicing, breakdown repairs and maintenance to keep your heating and hot water running.

What it is
A boiler service is a thorough safety and performance check of your boiler. Our repair service finds and fixes the fault when your boiler stops working, leaks, loses pressure or starts making unusual noises.
When you need it
Most manufacturers recommend a service every 12 months, and it is often a condition of the boiler's warranty. Call us straight away if you have no heating or hot water, the pressure keeps dropping or the boiler is showing a fault code.
How we do it
During a service we inspect the boiler and flue, check the gas pressure and combustion, clean key parts where needed and confirm that everything is working safely. For a repair, we diagnose the fault, explain what needs doing before we start, and then fix it.
