On a landlord gas safety check, the working pressure at the boiler we had fitted eight months earlier was only 14 mbar. Cadent had moved the gas meter to the front of the property, so the pipe to the boiler had gone from under 3 metres to over 12. We re-ran the supply in 28mm pipe, re-piped the gas hob, which had been connected on a hose, and tightness tested the installation. The working pressure at the boiler is now 19.5 mbar.
We attended a rented property in Sutton Coldfield for its landlord gas safety check. We had fitted the boiler eight months earlier, when the gas meter was less than 3 metres from it. Since then, Cadent had done work in the road and moved the meter to the front of the property, and the pipe run to the boiler was now over 12 metres. The working pressure at the boiler was only 14 mbar. We also found the gas hob connected on a hose, which we recorded as At Risk. We re-ran the gas supply in 28mm pipe, re-piped the hob, and carried out a tightness test to make sure there were no leaks. The working pressure at the boiler is now 19.5 mbar.

Smell gas now? Do not use this form or wait for a reply. Call the National Gas Emergency Service free on 0800 111 999 (24 hours). If you are using a mobile, make the call from outside. Open doors and windows, do not switch electrics on or off, do not smoke or use naked flames, and turn the gas off at the meter if it is safe to do so, unless the meter is in a cellar or basement. Once the supply has been made safe, we can trace and repair the fault.

We attended a rented property in Sutton Coldfield for its landlord gas safety check. We had fitted the boiler eight months earlier, when the gas meter was less than 3 metres from it.
Since then, Cadent had done work in the road and moved the gas meter to the front of the property. The pipe run from the meter to the boiler was now over 12 metres, and the working pressure at the boiler was only 14 mbar. We also found the gas hob connected on a hose, which we recorded as At Risk.

A meter move can change the pipe run the boiler depends on, even when nothing inside the house has been touched. An annual gas safety check is when a problem like this gets found. Our gas safety certificate page explains what the check covers.
A landlord gas safety certificate is £90 for the boiler and cooker, and each extra appliance is £15. Pipework like this is quoted on site and agreed before we start. Details are on our price list.
Gas loses pressure as it travels along a pipe, and it loses more in a longer or narrower pipe. Here the pipe from the meter to the boiler went from under 3 metres to over 12, so the old pipe was no longer big enough and the working pressure at the boiler fell to 14 mbar. A new 28mm supply brought it back to 19.5 mbar.
Flexible cooker hoses are made for freestanding cookers, which need to be pulled out from the wall. A built-in hob should be connected with fixed pipework. We recorded the hose connection as At Risk and re-piped the hob.
It means the installation is not an immediate danger to life or property, but it has the potential to become one. The engineer explains the risk, recommends turning the appliance off until the fault is put right and, with your permission, does so. Either way you are left a written warning notice that lists the fault and what is needed to fix it.
A test with a gauge connected at the meter that checks the gas installation holds its pressure, so there are no leaks. We carried one out after the new pipework went in.

Rust at the back of the heat exchanger and a carbon monoxide reading on the analyser, in a house with a young family. We capped the boiler off, told the tenant and landlord, and replaced the cracked flue collector and gaskets with the landlord's permission.

Read the case studyA smell of gas in the upstairs bathroom and a 20 mbar drop on Cadent's test. We traced the leak to old steel pipe, capped it off, tested and recommissioned, so the boiler was back on the same day. The hob now needs a new supply.
