CO2, or carbon dioxide, is a silent killer and as most people are more interested in carbon monoxide, it can often go undetected until it’s to late. The air we breathe has around 21% CO2 in it naturally and this suits us fine, however as the percentage rises and we inhale it, this noxious gas takes the place of oxygen in the blood stream and quickly poisons the body. High levels of CO2 can cause organ failure, brain damage and even death in some cases.

CO2 Dangers in the Home
Carbon dioxide is an odourless, colourless gas and is typically produced by gas boilers in the home. In a properly functioning system, the CO2 gas is released into the atmosphere outside the home through the boiler’s flue and there isn’t a problem. Should the flue become blocked or damaged though, the CO2 emissions can seep into the rooms around the boiler and cause poisoning. Even worse is when the CO2 is converted into carbon monoxide because of the lack of ventilation and this gas seeps into the house. CO2 poisoning can occur within minutes in extreme cases and once the victim falls unconscious then it is unlikely they will survive unless found by someone else.

Avoiding the Dangers of CO2
There are a number of ways to avoid a CO2 poisoning tragedy and most are easy to do and relatively inexpensive. So for example:

• You should arrange to have an annual boiler service performed by a Corgi registered gas engineer. These services check your boiler for excessive CO2 production and also check that the flue is fully operational and clear of any blockages or leakages. Should a problem be found then it can easily be fixed at the time of the service.
• Your home should have adequate ventilation which means that built-in vents shouldn’t be blocked in any way – from the inside or the outside. During the warmer months you can have windows and doors open to increase the ventilation if you think that there may be a CO2 problem.
• You can also buy a CO2 alarm which will alert you to the presence of high CO2 levels before they can do any damage. These alarms are inexpensive at around £20 and can be placed at various places around the home if you want, although one should be placed close to the boiler and flue for obvious reasons.

New boilers and flue systems very rarely cause problems however older boilers can and it is worth spending a few extra pounds each year to safeguard the people in your home. CO2 poisoning is quick and the gas is undetectable by the senses so paying out for an alarm to do the detecting is surely a small price to pay in anyone’s book – I know it certainly is in mine.

Plumbing is an industry and as we all know there are good guys and bad guys trying to get your attention and your money. Unfortunately, as I see it, things aren’t that simple as there are at least two boxes that have to be ticked for a plumber to be classed as good. Firstly he has to have the skills and secondly he has to have some scruples.

Plumbers who are highly skilled and have all the relevant qualifications can still be classed as bad plumbers in my book if they have dodgy scruples. So for example, your chosen plumber might turn up on time, diagnose the problem in a minute, fix the problem within an hour but then charge you an extortionate fee for his troubles. To me that still makes him a bad plumber and one I wouldn’t recommend to my friends or family. On the other hand there are the plumbers that charge reasonable rates but take an eternity to do the work because they’re not sure exactly what they’re doing. Again this doesn’t say ‘good plumber’ to me.

So what does a plumber need in order to be classed as ‘good’?

A quote that is reasonable and not too dissimilar from others – one of the golden rules when hiring any tradesperson is to get at least three quotes before agreeing to anything. A good plumber will give a quote that is similar in price to any others that you have – it may be a bit more expensive if they are a well established company but in general it shouldn’t be anything silly. They should also be able to guarantee that there are no hidden costs that aren’t on the quote, such as taking away old parts or waiting time while they order anything they need.

Word of mouth recommendations – any plumber that comes with personal recommendations is automatically classed as good. After all, you wouldn’t recommend a tradesman to your friends if he did a rubbish job, charged you the earth and left your house looking like a bomb site. Similarly you wouldn’t recommend him if he had awful manners, left the job half finished or ran off with all your valuables. Word of mouth is a good place to start when looking for a good, reliable plumber but if no one can come up with a name then you have the two factors above to fall back on.

If you look through any copy of the Yellow Pages or the Thompson Local you’ll find that plumbers are listed in their hundreds. Unfortunately not all of them can be classed as top quality – or even good quality in some cases – so how do you know a good plumber when you see one? 

Are they fully trained and licensed?
Any good plumber will be registered with the Institute of Plumbing. This means they either need to have passed a whole heap of qualifications, including their NVQs and such or they need to have 20+ years experience in the trade. Without these factors they wont get on the register. Some older plumbers may have the qualifications and the experience but in general this is rare. Regardless of which type of plumber you choose though, they should be able to provide evidence of their current registration with the official institution. Saying that, the Institute of Plumbing has recently launched a website that gives a full list of registered plumbers which makes finding one a much easier task for everyone.

Are they reliable enough to use?
It doesn’t matter whether you employ an individual or a company to do your plumbing work, they need to be reliable. One of the best ways to judge this is to make an initial appointment for a quote and see if they’re on time and looking the part. If they’re late or just don’t turn up then they aren’t the ones to go with and you need to look around for someone else. Choosing a reliable plumber comes easiest when they are recommended by a friend or relative that has used their services in the past. Ask around and see if anyone you know can recommend a plumber before trying the Yellow Pages.

Are they trustworthy?
For obvious reasons nobody wants to let someone into their home that can’t be trusted and especially not a burly plumber with rather menacing looking tools. But there are other ways that a plumber can be untrustworthy so you need to ask a few simple questions before hiring them for the job. For example, you should ask if they have an established premises for their business as this makes them less likely to do a runner with your money, ask if they have insurance that covers your property while they work on it, ask if they can give you the names of former customers so you can check on customer satisfaction and above all ask if their work is fully guaranteed. A good plumber who knows the trade will be able to answer yes to all of these questions. Then, once you’ve found a good plumber you want to make sure he stays in the industry so any time you can recommend his services, do it.

2009 will undoubtedly see a number of changes and advancements in the world of gas engineering however one of the most significant changes will be the name behind the UK’s gas registration scheme. The name CORGI is by far one of the biggest household names to date and when you mention it to someone they invariably know exactly what trade you’re talking about. So why would CORGI want to transfer the entire gas scheme to Capita – a name that very few ordinary members of the public will have heard of?

CORGI currently has two divisions to its business – the gas registration scheme and CORGI Services Limited. This lesser known part of the business offers a range of products and services to CORGI registered companies which help them to work more efficiently and it is this part of the business which is being developed. As such the gas registration scheme is being handed over to Capita and will have a brand new name which is being announced in January of 2009.

Not surprisingly over 80% of gas engineering companies say they retain more work because of their association with the CORGI brand name and that they want to continue to be associated with the name if possible. As a consequence CORGI have put together a quality and competency scheme which will launch in the next few months. Any company that is registered on the Capita gas registration scheme can also be part of the new CORGI quality scheme but if this is the case then why bother with the change at all.

It is estimated that over 90% of UK consumers have heard of the CORGI name; they know what it stands for and they know it means quality, qualifications and people that can be trusted. Until I heard of this new scheme, I’d have looked at an engineer with a very puzzled expression if they had told me they were Capita registered and I’m pretty sure the majority of other consumers will feel the same. Some marketing experts maintain that it takes several years and millions of pounds in advertising to successfully change a brand name and one as big as CORGI will undoubtedly be hard to change.

The transfer takes place in April 2009 and so until then the CORGI registration still stands. After that date though all qualified gas engineers will be Capita registered so this is the new phrase to look out for. Capita will be the new governing body and all registered engineers will have to pass the same rigorous exams as they did before in order to get their tickets. They will be just as qualified and just as dependable as ever – they’ll just have a new registration name to remember.
