The question most electricians are asking in this day and age is which CPS (Competent Person Scheme) to join - there seems to be quite a choice out there. Does it matter which one we choose? We could go with the well known few or alternatively try one of the other scheme operators. What are we getting for our money?

Well let's be clear about one thing - they are all equal! Each scheme has to be approved by the Department for Communuties and Local Government (DCLG) and all have to meet the same criteria. No scheme can therefore be discriminated against and one scheme should not be a preference over another in any contractual specification. To do so would be against the law.

So in reality it doesn't matter which scheme you choose, it's down to personal choice. Some are better than others if you want to move into the renewables sector. Most are upfront and explain their charges clearly. Some will even give you stickers for your vehicle; others don't - you have to pay for them! Some offer a workmanship guarantee as part of your membership, with others you have to purchase this separately.

So in my humble opinion, shop around and go for the scheme that offers your company the best service for you. Every scheme has to assess you to ensure you are working to a competent level; that is the important factor in all this, not which sticker you put on your van.

In 2013, the Government made important changes to Part P of the Building Regulations. These are the regulations that ensure that all fixed electrical installations in domestic dwellings are suitably designed, installed, inspected and tested to provide reasonable protection against becoming a source or fire or a cause of injury to persons.

These changes to the Part P of the Building Regulations consisted of two principel modifications, the first of which reduces the range of electrical installation work that needs to be notified. Previously, electrical work undertaken in kitchens (such as adding a new socket) or gardens (installing security lights) were among the work you'd need to be Part P qualified to perform without having to notify an inspector. However now these tasks will no longer be notifiable unless a new circuit is required.

There are three main areas where electrical work will still be notifiable due to Part P of the Building Regulations, and these are:

• Any work involving the installation of a new circuit
• The replacement of any consumer unit
• Any addition or alteration to existing circuits in a special location

It may be an apocryphal tale, but in the days of the Empire it is said that many passengers embarking for the tropics were persuaded to buy small packages labelled "Insect Destroyer", and further labelled with the instructions "do not open until required". When the packages were finally opened, it was discovered that they contained only two small blocks of wood and the instructions "Place the insect on one block and strike sharply with the other".

In these days of Consumer Protection and Trading Standards it might be hoped that this type of con is very much a thing of the past, but according to a report from the Electrical Safety Council, it is still very much with us. The latest manifestation is a range of "plug-in energy savers", normally sold over the internet pr at car boot sales.

These devices claim to save money on electricity bills by doing some kind of "conditioning" to the supply which makes appliances run more efficiently. This is nonsense. The Electrical Safety Council tested four different models, all of which actually increased power consumption rather than reducing it.

More worryingly, all the devices tested failed to meet basic product standards. In all cases the pin dimensions were not correct. This means that the device would be a loose fit in the socket-outlet, which would cause arcing and overheating. All the devices tested were also of poor internal construction, making them a fire hazard. Several of them were CE marked, but the poor quality of construction would suggest that these marks were almost certainly forgeries. 

There have been reports that these devices are also being sold over the phone. Many elderly people have been targeted by telephone sales calls purporting to originate with one of more of the energy suppliers. Often the caller has the persons' name and address, and on some occasions even part of their credit card number. These calls are bogus and originate overseas, many from a holding company in the USA.

If you should be offered one of these devices, Action Fraud (www.actionfraud.police.uk) would like to know. You can also contact them on 0300 123 2040.

This is a question posed by many a householder, however of the reality is that it might not need to be changed. If the fuse board is damaged and there's a chance that people could touch "live" parts (risking an electric shock), then it does need to be changed.

The old fuse board will not meet the requirements of the BS7671 Wiring Regulations 17th Edition Ammendment 1 (2011). The fact that the installation does not meet the requirements doesn't mean it is illegal or indeed unsafe, however the new requirements are intended to make the installation "more" safe by reducing the chances of getting an electric shock.

In order for your domestic installation to meet the requirements of the "Regs" it must also meet the new RCD (Residual Current Device) requirements. RCDs cannot be fitted in older style fuse boards so if your installation needs to be brought up to date and made safer a new consumer unit will be needed.

There are numerous areas where RCDs are required, which should be rated at 30mA. These include;

• Any cable buried in a wall or partition at a depth of less than 50mm from the surface requires protecting by an RCD unless it is protected by earthed metalwork such as conduit or trunking.
• Any cable passing through a wall or partition that contains metal parts other than screws or nails.
• Any cable that is installed outside the 'cable safe zones' needs protecting with both earthed metalwork and an RCD.
• Every socket outlet rated 20A or less that is used by "ordinary persons" (i.e. home owners) intended for general use, require RCD protection.
• Mobile equipment used outdoors rated up to 32A.
• All circuits supplying power to a room that contains a bath or shower are required to be RCD protected.

Thinking of going self-employed? Need to join a Competent Person scheme? Well if you don't have the current entry requirements (an electrical installation qualification, 17th Edition Wiring Regulation qualification plus anything else your chosen scheme requires of you), you may well encounter problems if you haven't applied for membership by 6th April 2013.

As of this date entry requirements to a Competent Person scheme are changing. You will need a level 3 NVQ that includes installing electrical installations, Inspection and Testing of electrical installations and Ensuring Compliance of Electrical Installations with building regulations.

Sounds easy? A number of awarding bodies have produced relevant qualifications, but the problem will be the time it will take people to achieve the required level of competence and produce a portfolio as the proof that all the elements have been covered. I would suggest that you will be looking at 18+ months to put the portfolio together!

The knock-on effect of this will be that no one will be eligible to join a Competent Person scheme for some time, causing a void in so-called competent persons. Home owners may find it difficult to find existing electricians that are prepared to take on small jobs - such as installing extra sockets (these are the kind of jobs newly qualified persons use to gain experience), as the current competent electricians will be looking for bigger contracts.

Does this mean home owners will be more tempted to "have a go" themselves? Causing mistakes to be made that could result in dangerous situations occurring? Possibly!
