Temperatures could soar to dangerously high levels in some homes insulated under the government's flagship Green Deal scheme, experts have warned. Energy-saving measures designed to save on winter fuel bills and protect the environment could pose a risk to health during summer heatwaves, they add. Homes in densely populated urban areas such as London are most at risk. The government says it is aware of the problem and is taking steps to prevent overheating in Green Deal properties.

Heat can build up during the day and has nowhere to escape at night leading to poor air quality and a greater risk of heat stress for the occupants which, in extreme cases, can kill. It is vital that homes in the UK are better insulated to help meet carbon emission targets and save on winter fuel bills. But the risk of overheating had been overlooked in the "big rush to insulate and make homes airtight", particularly as more extreme weather events, including heatwaves, are being predicted for the UK by meteorologists.

"Overheating is like the little boy at the back of the class waving his hand. It is forgotten about because the other challenges are so big," he told the BBC News website. Very effective measures are being taken to protect against winter temperatures but by doing that they increase the risk of overheating during summer.

Research by Leicester De Montfort University, suggests top floor flats in 1960s tower blocks, and modern detached houses were most at risk, particularly if they were south facing. Heat was likely to have the biggest impact on elderly or infirm people who remained at home all day, the research suggests. The elderly are going to suffer. Suffering means they are going to die from overheating.

Under the Green Deal, householders take out loans to finance improvements such as double-glazing, loft insulation or more efficient boilers. The idea is that the energy savings they make should more than compensate for the repayments. In total it said there had been 38,259 Green Deal assessments, where customers are given initial advice about what energy improvements they might be eligible for. Of those, 241 households have confirmed they would like to proceed with work.

According to research by a group of leading engineering and climate change experts, published last year, "Green Deal measures could create new problems in the future, with inappropriately insulated properties experiencing poor indoor air quality and significant summer overheating. It said the increased likelihood of summer heatwaves could lead to rise in heat-related deaths from 2,000 to 5,000 per year by 2080 "if action was not taken".

The Department for Energy and Climate Change says it has now issued fresh guidance to Green Deal suppliers to help reduce potential risk from installing energy efficiency measures.

He said there were simple measures anyone could take - whether living in a well-insulated home or not - to keep heat levels down, such as keeping windows closed during the day to trap cool air and opening them at night. Fitting shutters to windows and painting exterior walls white - both common sights in Mediterranean countries - would also help, but were unlikely to be widely adopted in the UK due to the relative rarity of heatwaves.

It’s happened to us all at some time or other, the job we have been putting off because it’s a little bit too big or we’re not sure how to do it. We bite the bullet and decide to get a tradesman in to do the work for us. Which tradesman? Where do we go to find out if the voice at the end of the phone is in fact a ‘quality’ tradesman and not John Wayne with a screwdriver?

You could go to www.trustmark.org.uk

TrustMark is a government endorsed scheme that regularly checks that the registered tradesmen are providing their customers with the quality service and workmanship members of the public expect and deserve (quite rightly). Trustmark registered firms have to;

  1. A firm's technical skills have been independently checked through regular on-site inspections, as well as checks on their trading record and financial status;
  2. Firms have signed up to a code of practice that includes insurance, good health and safety practices and customer care;
  3. The approved scheme operator has checked and will continue to monitor the firm's quality of work, trading practices and customer satisfaction;
  4. Firms are able to offer an Insurance Backed Warranty;
  5. Deposit Protection Insurance is available for consumers in the event a firm should cease trading;
  6. Firms will be able to tell you about any building regulations you must comply with and may also be able to provide appropriate certificates;
  7. If you have a problem or disagreement with the firm, there will be a clear and user-friendly complaints procedure to help resolve the issue;
  8. The scheme is fully supported by Government, the building industry and consumer protection groups.
  9. All of these checks will give you - Peace of Mind.

When employing a tradesman TrustMark recommends you take the following advice;

  • Be specific and set out a detailed, clear brief when requesting at least three quotes.
  • Ask friends and family for a recommendation and check the TrustMark website to ensure that the tradesman is registered for the particular trades you require
  • Use a firm that advertises using a landline phone number and be very wary of those only willing to give you a mobile number
  • Seek references, speak to previous customers and if a reasonable sized job, visit previous jobs
  • Don't just go with the cheapest, consider your ability to communicate with the firm and the quality of their work
  • Only pay for work that has been done and not by advance payments
  • If materials need to be bought in advance by the tradesman, it is reasonable that the customer is asked to pay a fair percentage of these costs as the job progresses
  • Always use a written contract as it offers you protection if anything does go wrong
  • Agree in writing any changes to the agreed contract value and ensure these are agreed in writing before the work is done.

If you use a TrustMark tradesman your work should be carried out to a high quality and if things go wrong (God forbid) you, through the scheme, have a means of recourse. That has to give you Peace of mind.

Summer holidays on the Costas are with us once again. Lots of families are jetting off to spend a week or two in the sunshine. All looking to have fun and this will probably mean consuming large quantities of alcohol.

But we have become so reliant on our electrical and electronic gizmos; we all need an adapter to charge them up whilst we are in foreign lands. Our UK standard plugs will not fit into the sockets that we find in our ‘little paradise’.

Off we go to the local supermarket to purchase an adapter – but they are not cheap, so plan B comes into action. Off we go to the ‘cheap’ shop (you know the ones – everything’s a pound!). But is that cheap product safe? Probably not!

The above item is the subject of a “Product Recall” as it has been identified as being UNSAFE.

“The product poses a risk of electric shock because the user comes into contact with live parts when inserting the plug into the socket. The product does not comply with the relevant national standard BS1363.”

What a wonderful holiday – a couple of days in the sun followed by a couple of days in hospital receiving treatment for electric shock and/or electric burns; if you lucky. If you’re not you might be flying home baggage class in a wooden box!

You can’t put a price on safety; remember it might by your child that gets the shock of their lives!

Research by the Electrician Technician Registration has found that "a lack of recognised standards for industry competence" is restricting both electricians' ability and their eventual career progression.

The study looked at how electricians' perceived their professional and discovered many were confused about what constitutes "competence" and which industry bodies could be called upon for careers guidance. Participants in the research also claimed that the vast amount of electrical qualifications available to them made it difficult to decide which routes of study to take in order to gain professional recognition. They also agreed that without a visible benefit of pursuing such qualifications, they feel no reason to aspire toward them.

In an attempt to address these concerns, the Technical Advisory Panel and Steering group (TAPS) - a collaboration of bodies including the IET, the Engineering Council, Electrical Contractors' Association and the Joint Industry Board, will now act on these key issues highlighted in the research;

  • Developing careers pathways to enable professional recognition for electricians to progress to engineering technician.
  • Adopting a 'one body' consistent approach to providing advice on a national scale with an electrician technician membership package.
  • Mapping the engineering technician professional standards to the established industry competence card schemes, NVQs and apprenticeship frameworks.
  • Promoting the benefits of gaining engineering technician recognition to support career progression.

common electrical problems

Some electrical problems are more common than others, and not everyone requires an intensive electrician course or professional qualification to deal with the issue at hand. With this in mind, here's a short list of five of the most common household electrical problems, and how they can be fixed with ease.

1. No power from an electrical socket

This common household electrical problem could be due to a number of things, some of which you will be able to fix yourself without the aid of a professional electrician. Usually, it's down to a tripped circuit breaker, or perhaps the fuse has gone.

Alternatively, it could be because of a loose wire somewhere. It's easy to check whether the circuit breaker has tripped or the fuse has blown, but if its neither of these you may need the aid of a power tester/voltage meter. If the test results in low or no power, it probably means the wiring is loose somewhere and requires further inspection.

2. Flickering lights

Again, this household electrical problem could be due to any number of reasons. Flickering lights or those that do not turn on/off when commanded are usually due to a larger problem, as is a buzzing sound you'll hear when the lights are on. The simple answer is that you might be using the wrong wattage light bulb, but it could also be a case of a bad connection. Whatever it is, in most cases this can be fixed by simply changing the bulb.

3. Half the house lights have gone off

We've probably all been here at some point. Usually, this household electrical problem can be fixed by locating your house's fuse box and flipping the switch (be sure all the light switches are off in the affected area though!). However once again it could be a short fuse or loose wiring somewhere. You might be able to locate this with your voltage tester/power meter but it's recommended that you call an electrician if needed.

4. Strange smell coming from switch/socket

When the circuit connection of an electrical device is damaged, the electricity jumps to complete the circuit. Not only creating this smell but also potentially resulting in a fire as the electricity zaps anything along the way. Electrical device arcing also indicates a serious damage to both the socket and electrical device. You'll need to unplug the appliance immediately and seek the help of a professional.

5. Hot switches

This usually occurs in dimming switches when they are running bulbs that are equal to or less than 600 Watts. When this happens, achieve the wattage required to run the dimmer properly by adding the right amount of bulbs. However, if it's the wall socket that's hot, you need to use a voltage meter to look for a high decrease or increase in voltage.

Hopefully, this post has helped you in being able to identify some of the common electrical problems you might find at home, and what you can do to fix them. However it is important to know your limitations, and NEVER attempt something that should be performed by a professional electrician.

Until the recent changes to Part P came into force (in England only), if you carried out an electrical task in your home your only option was to notify the work to the local building control office. Building control would then get a qualified electrician to come and test your work and issue the relevant certification.

The changes in Part P now make provision for the home owner to engage a registered third-party certifier to certify that the works meet the requirements of the building regulations and BS7671 2008 (2011).

A word of warning; the third-party certification scheme has not yet started, and is not expected to be in place until later this year.

The 2013 edition of Approved Document P, which applies to England only, makes provision for notifiable electrical installation work to be certified as compliant with the Building Regulations by a ‘registered third-party certifier’. However, those interested should note that, such a service can be provided only by a ‘registered third-party certifier’, who is ‘a competent person registered with a Part P third-party certification scheme’.

Competent persons registered with schemes that authorise them to self-certify that their own work complies with the Building Regulations are not automatically entitled to certify compliance of electrical work undertaken by others. Following development by the Department for Communities and Local Government (DCLG), the arrangements for third-party certification schemes are expected to be put in place later this year.

Registration with third-party certification schemes is expected to be available to named individuals from trading companies who meet particular assessment criteria intended to ensure that those individuals are competent to inspect, test and report on the condition of electrical installation work carried out by others.

The DCLG is not expecting competent persons registered with existing Part P schemes to use third-party certification in place of self-certification. The third-party certification option is intended for DIYers and other unregistered installers who currently notify their work to local authorities.

Within industry I feel there is a very bad trend at the moment, many firms are trying to save money in the wrong ways. The main concern I have is with the plumbing and gas industry and their blatant disregard for Electrical safety. There any many companies that put pressure on their installers to wire the heating systems.

News flash - they are not qualified and indeed nowhere near competent to do so, unless they have received adequate training. It might save money in the short term but imagine the lawsuit when someone’s house is on fire or someone dies from an earth fault because of inadequate Earthing.

As an Electrician I’m fed up of being approached by these companies asking if I could sign off their work. Quite frankly a majority of the time their work is like that of a child and nowhere near the standards required for me or any other sane Electrician to put their name to. I have worked for many heating firms over the years and the only way to ensure safety and quality of work is to have a competent Electrician to do the wiring, in my experience one Electrician can easily wire three to five heating systems a day.

This is where I get the title “each to their own”. I am not expected to connect up a gas pipe and I would never attempt it! But Heating installers are encouraged to do Electrical work and in my eyes its madness unless they have received adequate training.

Not all electrical work requires a trained professional. Minor tasks such as replacing a light switch can be performed without having to notify your Local Authority Building Control Department, however they still must be done to current Building and Electrical regulation standard.

While there are a wide variety of different types of light switch you might find in the home (including pull-cord switches, narrow architrave switches and rotary dimmers), here is a guide to the most basic of them – the one-way and two-way switch. The difference between them is that two-way switches are used where there is more than one switch connected to the same light (e.g. at the top and bottom of the stairs).

 

Safety first

Before you start ANY sort of electrical work make sure the power is switched off at the main consumer unit OR switch off the relevant circuit breaker and lock it if you can. Then make sure that the circuit is indeed dead using a voltage tester/meter. Also take note that since 2006 the core colours inside electrical cables have changed. In the new two-core-and-earth cable, the live or phase core is insulated in a brown sheath rather than red. The neutral core is now blue as opposed to black.

 

What you will need:

  • Voltage tester/meter
  • Side cutters Screwdrivers
  • Green/yellow earth sleeving
  • Suitable replacement plateswitch (1 or 2-way)
  • Screws
  • Brown PVC electrical tape or sleeving
 

For one-way switches:

Step 1: Isolate the circuit and then confirm that the power is off using your voltage tester. Unscrew the switch faceplate and pull it forward, revealing the connections behind. These terminals will usually be marked something like L1, L2 and COM.

Step 2: Draw a diagram so that you remember which colour and number of wires were attached to each terminal. Then release the terminal screws and pull the cores from them. If the earth core is properly insulated in green/yellow sleeving and connected to the mounting box, leave this attached.

Step 3: Connect these cores to the correct terminals of the new switch, using your diagram as a reference. Tighten the screws and check they are clamping the cable cores firmly by gently tugging the wires.

Step 4: If there isn’t one already, fit a length of brown sleeving over the blue core to indicate that it is a switched live.

Step 5: If it’s not already fitted, put some green/yellow sleeving over the bare earth core of the incoming cable and connect it to the earthing terminal of the mounting box. If you’re using a metal switch, be sure to earth the switch faceplate as well.

Step 6: Double check that each connection is secure, then push the cable back into the mounting box and fit the faceplate.

 

For two-way switches:

While this is similar to a one-way switch there will normally be three cores to the cables – coloured brown (formally red), black (yellow) and grey (blue). Again these terminals will be labelled something like L1-3 and COM.

Step 1: Isolate the circuit and make sure the power is off with your voltage tester.

Step 2: Remove the faceplate from the existing switch and disconnect the cable cores.

Step 3: Note which colour goes to which terminal (write it down if you think you’ll forget!) and then transfer them to the corresponding terminals on the new switch.

 

While this is simply a brief guide to some of the electrical work you can do yourself around the home, more technical electrical work will require you to have a Part P qualification if you wish to carry it out yourself. If you are interested in learning about more work you can do or achieving Part P qualification then the best way is to learn from one of Access Training’s comprehensive electrical training courses. Offering professional qualifications to both aspiring and existing electricians as well as DIY courses, there truly is something for everyone regardless of age, gender, background or experience.

Although Part P Building regulations require a qualification to undertake extensive electrical work in your own home, minor tasks such as replacing damaged sockets or light switches can be done without having to notify your Local Building Authority Control Department. In this post we'll take you through a few simple steps to replace a plug socket or alternatively change a single one into a double.

 

Safety first

Before you start ANY sort of electrical work make sure the power is switched off at the main consumer unit or switch of the relevant circuit breaker and lock it if you can. Then make sure that the circuit is indeed dead using a socket tester. Make sure to also have protective gloves and safety goggles on you at all times.

Also take note that since 2006 the core colours inside electrical cables have changed. In new two-core-and-earth cables, the live/phase core is insulated in a brown sheath as opposed to a red one and the neutral core is now blue rather than black. If you are connecting old and new cables together, take extra care to make sure that the cores are attached by their corresponding colours.

 

What you will need:

  • Socket tester & socket template
  • Screwdriver
  • Pipe and cable detector
  • Drill
  • Socket faceplate or new double socket
  • Wall plugs and screws
  • Mounting box
  • Green/Yellow pvc sleeving

 

To change a damaged socket:

Step 1: Confirm you have switched off the main power using your socket tester. Once sure unscrew the socket faceplate and pull it away from the wall. Keep the screws just in case the new ones don't fit.

Step 2: Loosen the terminal screws and release the cable cores. Should the insulation be heat damaged, cut back the cores and strip the ends. If the earth core is bare, cover it with the green/yellow sleeving.

Step 3: Connect the brown (or red) core(s) to the live terminal of the faceplate, the blue (black) ones to the neutral terminal and the earth core to the earth terminal. Tighten the screws fully and fit the new faceplate. When you have turned the power back on, use the socket tester again to check it is wired correctly
 

To change a single flush socket to a double:

Increasing the number of sockets in a room isn't as difficult as it might sound if you follow these simple steps...
 
Step 1: Isolate the circuit and then use the socket tester to make sure that it is dead. Unscrew the faceplate and disconnect the cables from the single socket mounting box.

Step 2: Knock out the middle section in the double box and pass the cables through. Mark where the screw holes are on the wall using a pencil, remove the box and drill.

Step 3: Screw the new box in place and connect the cables to the terminals. Fit the new faceplate and then test using the socket tester again once power has been restored.
 
Hopefully after reading this you'll feel confident enough to do these tasks yourself without having to pay for a professional electrician! However if you're interested in learning more about what electrical tasks you can perform at home with the right training, or alternatively hoping to gain qualifications to become an electrician - look no further than Access Training's range of bespoke electrical courses. From Part P to PAT Testing and wiring regulations to DIY, we offer something for everyone regardless of age, background or experience.
