When we attended the Ferroli Tempra 30 system boiler, we could smell gas in the airing cupboard. The gas valve was passing and leaking at its gasket, so we made it safe, quoted for a replacement and showed the customer how to use the immersion heater for hot water. Two days later we fitted a Worcester Greenstar 8000 Life 30kW system boiler, with a filter and a chemical flush.
When we attended a Ferroli Tempra 30 system boiler in Solihull on Tuesday 3 November, we could smell gas in the airing cupboard. The boiler's gas valve was passing and leaking at its gasket. We classified the boiler Immediately Dangerous: the gas was isolated, the boiler disconnected, and a warning notice and label left. We quoted for a replacement the same day and showed the customer how to use their immersion heater, so they still had hot water. On Thursday 5 November we fitted a Worcester Greenstar 8000 Life 30kW system boiler, with a filter on the heating system and a chemical flush, registered for a 10-year manufacturer guarantee.

When we attended the customer's Ferroli Tempra 30 system boiler in Solihull on Tuesday 3 November, we could smell gas in the airing cupboard. We found the boiler's gas valve passing and leaking at its gasket.
We classified the boiler Immediately Dangerous: the gas was isolated and the boiler disconnected, and we left a warning notice and a label on the boiler, which you can see in the first photo. The customer has a hot water cylinder with an immersion heater, so we showed them how to use it and they still had hot water. We quoted for a replacement the same day.
The customer accepted, and on Thursday 5 November we took out the old Ferroli and fitted a Worcester Greenstar 8000 Life 30kW system boiler in the same cupboard. We fitted a filter on the heating system, chemically flushed the system, and registered the boiler for a 10-year manufacturer guarantee. The customer was very happy that we could fit it in so soon. Our boiler installation page explains how a replacement runs.
System boiler replacements like this one have no list price: they are priced in writing after a free survey, and everything is agreed before we start. Combi swaps are from £1,999 fitted. Details are on our price list.
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. Then call the National Gas Emergency Service free on 0800 111 999, from outside if you are using a mobile. They will come out and make the property safe. If they find a leak on the pipework after the meter, you then need a Gas Safe registered engineer to find and fix it.
It means the appliance is a danger to life or property as it is. With your permission, the engineer disconnects it from the gas supply and labels it, and you are left a written warning notice that lists the fault. It must not be used again until the fault is put right.
If you have a hot water cylinder with an immersion heater, yes. This customer had one, and we showed them how to use it until the new boiler was fitted.

The old boiler had been condemned and switched off. We fitted a new Worcester Greenstar 18Ri ErP, a magnetic filter and a chemical flush, and registered it for a 10-year guarantee.
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.
Read the case studyThe right-hand manifold inside a Worcester Greenstar 28i Junior was leaking. We diagnosed it, tracked the part down locally, fetched it and fitted it the same day. Customer extremely happy.
