Maintenance Services Electrical - News & Information
By June this year smart meters had been installed in 12.5 million households, so there’s still a long way to go.
New smart meter specification
The new smart metering equipment technical specification 2 (SMETS 2), comes into force this month.
The government wants energy companies to replace all old-style gas and electricity meters in 36 million households and small businesses with new smart meters by the end of 2020
Smart meters will become part of a nationwide digital network to help manage energy demand. They will transmit data to utility suppliers via a national network. There will be no need for meter readings and they will be transferrable between energy suppliers.
However, many of the earlier smart meters aren’t compatible with the network, meaning they won’t work if customers change suppliers.
The energy regulator, Ofgem, is allowing 12 suppliers to continue installing the old-style smart meters to help with the smooth introduction of the new standard.
Dangerous flexible cord discovered
Flexible cords and cables, either with plugs or in permanent wiring, are invaluable in domestic and commercial installations.
However, unsafe flexible cord has been found on sale in the UK, and a new alert has been issued.
The rogue cords are marked ‘Made in Turkey’ and ‘Ermaks’ and the Approved Cables Initiative (ACI) is warning that they should not be used. Samples can be sent to the ACI (minimum 5m length) for testing and checking by a qualified electrician is advised.
They were discovered following a recent ‘Counterfeit Flexible Cords’ campaign. The ACI believes that the manufacturers reduced production costs by using copper clad aluminium (CCA) as the conductor. CCA isn’t as tough as copper and will break more easily. Testing showed CCA conductor’s resistance was higher than required by British and European standards, creating a significant fire risk.
White light is good for car parks, giving good visibility and reassurance. It will also help with CCTV images.
Car park lighting
Darker mornings and evenings remind us that the year is winding down and that it’s time to make sure car park lighting is working properly.
Depending on how busy the car park is likely to be, the lighting levels could be as high as 20 lux. You’ll also want to be sure that there aren’t any dark spots due to lamp failures.
Modern LED lights can be very effectively controlled to minimise glare and to target exactly the right areas so that people can see and be seen.
If there are peak times, for example when everyone arrives for work and leaves again, you might want to consider dimming controls. This will provide energy savings and avoid annoying your neighbours with over-lighting when it isn’t needed.

One in four of us own a smart home device
According to the government’s new Smart Homes Report almost a quarter of us (23%) now own one or more smart home devices (and that doesn’t include smart meters).
Smart speakers remain most popular (one in ten people have these), with the Amazon Echo speaker being more than three times more popular than its nearest rival.
Once you own one device, you are much more likely to buy more, including smart thermostats (6%), lighting (5%), health tracking devices and security equipment (3%).
While the majority of non-owners are aware of smart devices, the government’s report highlights that they are concerned about security and data privacy. Many others just don’t see how they would benefit.
Smart meters are different. Many are free in most cases, and 18% of us currently have one to measure our gas and electricity consumption and to send automatic readings to utility providers.
In theory this should give us more control over our energy use and save money too. However there have been some concerns about their accuracy.
The government says it wants every home to have one by 2020, although you can opt out.
Can you imagine how many old lights it would take to fill the Royal Albert Hall ten times over?
It’s around 300 million – and that’s how many Recolight has funded for recycling since the Waste Electrical and Electronic Equipment (WEEE) regulations were introduced in 2007.
Recolight is the UK’s leading scheme for recycling old fluorescent and LED lamps and luminaires.
It has a dedicated open collection network for consumer and business lighting waste across the UK. With 3000 collection points for old fluorescent and LED lamps, it has helped to increase the UK’s lamp recycling rate from 39.5% in 2012 to 48.5% in 2017.
BSI Kitemark for commercial lighting
A new scheme to improve the safety and quality of commercial lighting products has been launched by British Standards Institute (BSI) and the Lighting Industries Association (LIA).
The scheme is also intended to reduce the risks of product recalls and returns by improving product standards.
The new BSI Kitemark for Commercial Lighting was developed because of concerns across the UK lighting industry about the growing number of low-quality products.
Because the Kitemark is recognised and trusted it adds weight to the seriousness of this issue.
The scheme will give a coordinated approach to third party certification. It will confirm compliance with safety requirements and support manufacturer’s performance testing claims, helping to improve confidence in the quality of products.
A webinar giving further details of the scheme is available on the LIA website.
Information is also available on the BSI website.
Each year around 12,500 house fires, 750 serious injuries and 10 deaths are caused by unsafe electrics in the home – some being the result of DIY projects that have gone wrong.
The ‘Ban the Bravado’ campaign aims to raise awareness of the risks of amateur electrical work and encourages people to use only qualified and registered professionals.
Don’t risk DIY electrical work in your home – give us a call.
Brave or Bravado?
Every Bank Holiday home owners across the country start new do-it-yourself projects.
With the August break approaching, the National Inspection Council for Electrical Installation Contracting (NICEIC) and the electrical safety body, ELECSA, say they are ‘encouraging Britain’s blokes to ditch the DIY and go pro.’
Some gardening or home decoration could save you money but some people – and, it has to be said, mostly men – also undertake electrical DIY. The results can be dangerous.
Research by the NICEIC and ELECSA shows that almost two thirds (61%) of the UK’s men would happily have a go at DIY without any experience. Of these, 38% say they would attempt electrical work, compared with just 8% of UK women.
Combine this with the fact that 61% of men admit their DIY skills are average or below and warning bells should be ringing.
The electrical world is full of letters and terms – here we explain some of them.
If the term you’re looking for isn’t here, please get in touch and we will be happy to tell you about it and add a simple explanation to our list.
AC - an abbreviation for alternating current. Electricity is all about electrons travelling through a conductor (like copper). When electrons alternately move in different directions it is an alternating current. AC current us used for homes and businesses.
DC – an abbreviation for direct current where the electrons are all moving in the same direction. DC current is used to charge batteries, for electronic systems, some industrial processes and high voltage power transmission.
Amp – the unit for measuring electrical current.
BS7671 – the UK national safety standard for electrical installations, also known as the wiring regulations.
Circuit – electricity needs to flow continuously, without any breaks, and this is called a circuit.
Consumer unit – used to control electricity. The unit will often include a main switch, fuses, circuit breakers or residual current devices (RCDs).
Current – the more electrons travelling through the conductor, the more power they deliver. Large electrical currents are dangerous.
Earth – the earth wire will direct the electricity straight into the ground rather than passing through you. Earth wires are usually marked with yellow and green striped plastic covers.
Fuse – a key part at the beginning of an electrical circuit to prevent too much electricity from passing through wiring. Often a circuit breaker will cut power when something is overloaded to prevent the cable and equipment overheating and becoming a fire hazard.
Insulation – a coating, usually plastic, around conducting materials.
IP rating – categorisation of safe lighting. For example, high IP ratings are for bathrooms or outside and lower IP ratings are for indoor lighting.
Joule – the unit for measuring electrical energy.
Live – a wire carrying electricity, commonly coated in brown plastic (note - older systems might include live wires covered with red plastic). You can receive an electrical shock from live wires.
Neutral – a neutral wire completes an electrical circuit and allows electrons to flow. Neutral wires are usually covered in blue plastic (note - older systems might use a black plastic covering).
Part P – a section of the Building Regulations for England and Wales about electrical installations in domestic properties.
Transformer – used to change voltage, to dim lighting for example.
Voltage – the unit for measuring the force of electricity moving through wires. High voltage locations are often marked as dangerous.
Watt – a unit to measure electrical power.
