All you need to know about smart meters


Over recent years you may have heard about the role out of smart meters across the UK, which make it easier to manage your energy use and bring an end to estimated billing. A smart meter tracks your energy use, and sends it over a secure mobile network to your supplier, meaning the end of submitting meter readings manually. How secure are they, and what if you want to change supplier? And The really big question, what about accessibility? Read on to find out more.

Getting a smart meter

A smart meter is free to have installed, and is done by a qualified person who works for a third-party organisation on behalf of your supplier. The time for installation typically takes 1 to 2 hours, in which time your existing meters will be removed and replaced with smart meters. If you have a supply for both gas and electric, 2 smart meters will be included.

How do they work?

The smart meter comes with an in-home display, known as an ‘IHD’, which is a small battery operated device which can be carried around your home, and placed in to a supplied charger to recharge the battery. The display allows users to track energy usage, such as what is using most energy at a particular time, as well as allowing users to set budgets if on a pay-as-you-go tariff. The smart meter is responsible for uploading your data to your supplier. The smart meter works on a secure mobile network, and will not need a separate mobile connection. Its secure because only your energy usage is transferred to your supplier, nothing else which identifies you. Any software updates are done remotely over the secure network. Your smart meter may not work if there is no mobile signal at your property though, and may cause problems when attempts to upload data due to signal failure.

How accessible is it

Smart meters are being rolled out starting from June 2019, after a trial period to ensure that the IHD is accessible. Once available, it is possible to ask for the accessible smart meter as required, which again will be installed for free. The smart meter will have tactile buttons, voice output, and contrast options as required.

General Limitations

At the time of writing this blog, I asked some of my colleagues here at DAC on their views of smart meters. One colleague told me that the IHD would be difficult to sea, and they were waiting to sea what features the smart meter had. Another colleague informed me that the mobile signal was not good enough to send a signal to the energy provider, so it was not possible to have one installed. My own personal experience is that a smart meter could not be installed at the property where I live, due to the location of the meters, and the structural design making it difficult to remove and include new meters. In conclusion, it really does depend on a number of factors weather or not a smart meter will be installed, and of course accessibility is a primary concern, however its not the only obstacle.

Digital Accessibility Centre (DAC) supports international day of persons with disabilities

What is it?

International day for persons with disabilities (IDPD), was first observed on the 3rd of December 1992, and has been an annual event since then. The event promotes the rights and wellbeing of disabled persons throughout the world, and focuses on an equal place in society for all. Each year a different theme is adopted, and following on from last year’s theme of ‘transformation towards a sustainable and resilient future for all’, this year’s event is focused on ‘empowering persons with disabilities for the inclusive, equitable and sustainable development envisaged in the 2030 Agenda for Sustainable Development.’ The 2030 agenda is aimed at providing ultimately a full and equal part in society for persons with a disability, by working within the 3 areas of human rights, piece and development, and security. Taken from the United Nations page about international day of persons with disabilities (external link).

To support IDPD, DAC have produced a video of one of our staff members, who talks about how his loss of vision affects him both on a professional and personal level. Physical disabilities though are not the only consideration, its worth remembering that there are many hidden disabilities which are miss understood, or not acknowledged. Persons who experience mental illness, or other life changing events are often not understood to have a disability, and can encounter different experiences depending on how they feel from day-to-day. It is not uncommon for people to have days where they feel worse than others, which again can cause difficulties when seeking support or going about their daily lives.

DAC employs members of staff which cover both physical and hidden disabilities, and we will be releasing another video over the next few days to give a view from another staff member with a hidden disability.

Introducing FlickType, an accessible third-party keyboard for VoiceOver users on iOS


There are many ways which iOS can be customised to improve text input, from handwriting mode, braille mode and the various typing options when using the iOS default keyboard. As smart phone use has increased among blind and low-vision users, the approach to text input has long been a debate, with various options for typing. While it is possible to use a third-party keyboard, sometimes a quicker way of typing has often been the wish of many iOS users.

What is FlickType and how does it work?

Earlier this year, FlickType hit the iOS app store, with amazing results. FlickType enables blind and low-vision users to type quickly using its third-party keyboard, by tapping where they think the letters are on the screen. The app uses a powerful algorithm to interpret the tap of each letter, and brings up a list of suggestions based on what was entered. The user can then flick down with 1 finger to move through the list of words, and flick to the right to select a word, before typing the next one. Readers will be forgiven for thinking it sounds confusing, however having used FlickType myself for 6 months, I can confidently say that I can type just as fast as my sighted peers. One of our analysts said this about FlickType. "I love this ap as I can add words that FlickType does not recognise to the dictionary. For example, my name is Tehani which, the algorithm itself won't recognise. Adding this to the dictionary means that I can sign off all my emails without needing to cycle through all the suggestions that aren't relevant".

What can you do with FlickType?

You can do everything that can be done with the standard iOS keyboard with FlickType, including editing, and inserting your favourite emojis. It is also possible to include any custom shortcuts you may have used with the iOS keyboard, such as the abbreviation ‘OMW’ for on my way. It is possible to export text you have typed if just using the standard app, to iOS notes, mail and so on. However, if using the keyboard option, you can use the keyboard in your chosen app also.

JAWS verses NVDA


One of our new analysts Tehani, gives us her view on screen reader preferences, and why she prefers one over another.

Today screen reader users are spoilt for choice when it comes to choosing the right software to meet their needs. In the past, Jaws (Job Access with Speech) had the monopoly. There was supernova, but that didn’t fully meet my needs as a screen reader user. Jaws remained the preferred choice, and will always have a following due to it being one of the original screen readers blind people were trained to use. These days however, voice over and NVDA (None Visual Desktop Access) are starting to be a real alternative, and freedom scientific have to work hard to keep their customers happy.

Recently, NVDA has been receiving many positive plaudits for their work. I was a loyal Jaws user throughout my time in college and university until my husband and I had to consider getting a screen reader for our laptop at home. At college, Jaws was already on the computers, and at university, my disabled student allowance paid for a copy of the same software. We ended up deciding to try NVDA as there was no way that we could afford to spend £800 on Jaws, especially as we would need to spend more on upgrading in the future. In terms of mobile use, I had always used talx on Nokea, so when voice over became available on IOS I switched to that. No more paying for a device, then even more for a screen reader. Learning to use a touch screen took a lot of time but now I wouldn’t go back.

In my opinion, learning to use NVDA was the best thing we could have done, as I personally find it more responsive and intuitive than Jaws. For example, I find it much easier to access all elements from within one list rather than needing to remember several different short cuts. I can still use Jaws, and do so for my job, but honestly, I believe that in future web aim screen reader surveys, NVDA will certainly catch up, if not overtake freedom’s efforts. Saying this, due to its popularity, Jaws will always remain one of the screen readers of choice, especially for students going to university or college.

It is clear from my discussions with colleagues about screen reading technology that opinions are still mixed. When I set about writing this article I had a discussion with my colleagues to find out their views on the various screen reading software available. Starting the discussion, I thought that NVDA would be preferred overall, but I was surprised to discover that support for Jaws was still strong despite the cost and its complexities. I do believe though, that if Jaws is to continue to be a viable option to screen reader users, the cost will have to come down dramatically in order to compete with free options such as NVDA and voice over.

A brief explanation of the EU Accessibility Directive


From September 2018, all public sector websites will need to conform to the new European accessibility directive. The directive has some exemptions, and provides additional time for some organisations to update their content and policies which I will detail below. So what is it, how does it affect you? Who is it aimed at? And what about Brexit? All these questions are answered in this post.

What is it?

The directive exists to ensure that all public sector organisations websites and apps are accessible, using existing accessibility standards. It aims to unify the standards throughout all EU member states, and requires that all members have a process in place for testing, and ensuring an on-going commitment to accessibility moving forward.

When does the EU directive take affect and what should I do?

All member states need to comply with the directive from September 2018. As the UK is still part of the EU by this date, it also means that UK public sector organisations should adopt the new directive. Using existing guidelines which form part of the Web Content Accessibility Guidelines (WCAG), members should ensure that as much content as possible is accessible to all users of desktop and mobile devices, including website and app content respectively. Point 19 of the EU directive indicates this to include textual and none textual information, including downloadable forms and documents, identification and payment processes. Taken from section 19 of the directive: ‘EU Accessibility Directive ST_9389_2016_REV_1_EN’.

What if I add content which is inaccessible?

If content becomes inaccessible, or poses a significant barrier to accessibility resulting from an update and is available for the general public to view, suitable alternatives should be provided to resolve any potential access issue as part of reasonable adjustments. All websites should have an accessibility statement detailing how their offerings can be accessed on desktop and mobile devices, and should list any limitations, such as items which are out of the control of the organisation.


A list of exemptions are included within the directive, to take in to account a variety of scenarios based on other factors which effect public sector organisations. An exemption in this instance means that at the moment, an organisation will not be required to comply, or an organisation will have more time to implement a solution based on their activity online. Point 22 of the directive does indicate that items which may currently be exempt, are subject to change if it is deemed possible to implement accessibility at a later date. In the same way as WCAG, all content should follow the same 4 principles which are:

    1. Perceivable, meaning that content should be displayed in a way that is easily navigated by all users on multiple devices.
      Operable, meaning that all content should be able to be displayed and interacted with by multiple users on a wide range of devices.
      Understandable, meaning that the content and user interface should be presented in a way which is easy to understand and use.
      Robust, meaning that all content and controls will work with a wide range of software including assistive technology.

  • What are the list of exemptions?

    There are several factors which mean that specific organisations may be exempt, however this depends on the operation of the organisation at the time of the legislation being adopted. The following are deemed as excempt as long as certain criteria are met. 1. Office documents, such as spreadsheets and PDFs, published before 23 September 2018; 2. Pre-recorded live video posted before 23 September 2020; 3. Live video (for example, a live press conference); 4. Online maps and mapping services, as long as there is an accessible version providing essential information for navigational purposes; 5. Third-party content which the public sector body has no control over; 6. Reproductions of items in heritage collections which are too fragile or expensive to digitise; 7. The contents of extranets and intranets published before 23 September 2019; 8. The content of web sites and apps which are considered archival, meaning they are not needed for active administrative purposes and are no longer updated or edited; 9. The web sites of schools, kindergartens, and nurseries, except for content pertaining to administrative functions. Taken from The Web Dev Law blog on the EU Accessibility Directive (external link).
