Are Smart Meters Good Value?

Over time the cost of the Smart Meter roll-out have been going up, and the benefits have varied.

In September 2019 the Department for Business, Energy & Industrial Strategy (BEIS) said that the latest costs were £13.480bn, with benefits of £19.457bn, giving a net benefit of £5.977bn.

In 2016 the Department for Business, Energy & Industrial Strategy (BEIS) said that the latest costs were £11.0bn, with benefits of £16.7bn, giving a net benefit of £5.7bn.

In 2014 the UK Public Accounts Committee (PAC) said that the costs were £10.9bn, with benefits of £17.1bn, giving a net benefit of £6.2bn.

In 2011 the National Audit Office (NAO) said that the costs were £11.3bn, with benefits of £18.6bn, giving a net benefit of £7.3bn.

The Latest View of Costs

The latest view of costs (September 2019) £13,480M breaks down as follows:

Smart Metering Costs 2019

Cost Item	Value	%

Suppliers will recover this cost from customers over a number of years. The maximum added to bills was £11 in 2018. After that year the benefits gradually increase and by 2034 the average bill is reduced by £36.

The Latest View of Benefits

The latest view of benefits (September 2019) £19,457M breaks down as follows:

Benefit Area	Value	%
Customer Benefits	£7,623M	39%
Supplier Benefits	£8,071M	41%
Demand Shifting Benefits	£1,363M	7%
Network Benefits	£374M	2%
Carbon and Air Quality Benefits	£2,026M	10%

What are these benefits and how will they be realised?
The most relevant item to customers is the Customer Benefits through energy savings. These savings come from customers reducing their demand because they can see on their IHD the amount of energy that they and their appliances use.

Here is an explanation for each benefit figure:

Benefit	Explanation
Customer Benefits	With near real-time information on energy use and costs, customers are expected to make energy savings through enhanced energy efficiency behaviour.
Supplier Benefits	Suppliers can make a range of operational cost savings : They remove the need for site visits to collect meter readings and are expected to reduce suppliers’ call centre traffic, with fewer queries about estimated bills. Smart meters are expected to make the customer switching process cheaper and simpler, thanks to accurate billing and more streamlined interaction between involved parties through on demand meter readings at the point of switching. Suppliers should see improved theft detection and debt management. Customers will also be able to avoid proactively the accumulation of debt, through access to and consideration of accurate, near real-time energy information.
Network Benefits	Network operators will be able to improve electricity outage management and resolve any network failures more efficiently once a critical mass of smart meters has been rolled out; and they will be able to realise further savings from more targeted and informed investment decisions.
Demand Shifting Benefits	By enabling time of use (TOU) tariffs which tend to shift a proportion of electricity generation to cheaper off-peak times, smart meters are also expected to generate savings both in terms of distribution as well as generation capacity investment.
Carbon and Air Quality benefits	This reduction in energy use also brings with it a reduction of carbon emissions and an improved air quality.

Trading off the costs and benefits together there is a net benefit of £6bn resulting in lower energy bills for customers. Residential customers will have seen their average dual-fuel bill reduce by £36 in 2034.

A survey published in November 2016 by ECTA Training found that 44% of customers say that their energy bills have reduced after having a smart meter installed. (Updated: 2019-12-22)

Questions & Answers

How much will it cost me to run my In Home Display?

Your In Home Display (IHD) uses a very small amount of electricity. A typical IHD left on all year will cost less than £1 to run. (Updated: 2016-07-18)

Why are smart meters controversial?

Whilst earlier conversations about smart meters focused on safety (which you can read more about in Campaigns Against), more recent criticisms have sprung from how the government and suppliers are handling the roll-out. From cost to customer communication, the plan to get a smart meter into every home by 2024 has been a bumpy ride so far. In early 2014, EDF Energy, ScottishPower and npower called for a review of the roll-out, stating the cost to customers would be £1.8 billion. This, they said, was due to the "ambitious" deadline of every household in four years and the cost of the In Home Displays. The cost is ultimately paid by customers through measures on their energy bills. Instead, suppliers proposed, customers could link up their smart meter to their smartphone or tablet to save cost. In 2013, independent research commissioned by uSwitch found that 55% of us were "in the dark" about smart meters. That meant households did not understand what smart meters did and how they could benefit them. However, later studies of those with actual smart meters in their homes enjoyed more accurate billing and were more satisfied with their providers. (Updated: 2019-12-22)

Will a smart meter save me money?

A smart meter itself won't save you money, but the In Home Display (IHD) your smart meter comes with can offer much insight into how to lower your bills. Your IHD lets you see how much energy you are using at different times of the day, week, month or year, which should help you cut your energy usage and your bills by highlighting ways you can be more energy efficient.
The Centre for Sustainable Energy has advice on Smart Meters and other ways to save money on energy.
Also over time the technology will lead to the creation of innovative new tariffs and personalised plans individually tailored to fit your lifestyle and energy consumption. (Updated: 2019-10-21)

What is the cost of the meters?

Traditional meters (sometimes called dumb or legacy) meters lasted for about 40 years and cost about £7 for an electricity meter and £17 for a gas meter. Prepayment meters were more expensive for both electricity and gas, costing £43 and £95 respectively.
Electricity Smart Meters cost about £36 and gas meters about £53. The life is not yet certain but expected to be from 10 to 15 years. (Updated: 2019-12-22)

What are the benefits of having a smart meter?

There are a number of benefits if you have smart meters:

More accurate bills
Smart meters mean the end of estimated bills, and the end of overpaying (or underpaying) for your energy
No one has to come to your home to read your meter; you do not have to submit meter readings yourself
Better oversight and management of your energy use with a real-time data display in your home potentially saving you money.

What is the cost of the In Home Display (previously known as an SMD or HEM)?

In Home Displays (previously known as Smart Meter Displays or Home Energy Monitors) are provided free to customers and cost suppliers about £15. Some suppliers are expected to offer enhanced Displays at a cost to the customer.
Suppliers have an obligation to replace a broken IHD in the first year after installation. (Updated: 2019-12-22)

How much will a smart meter cost me?

Your supplier will install your smart meter for free under the national upgrade programme that begun in 2015. All households currently pay for the cost of their meters and required maintenance as part of their energy bills, this will be the same with smart meters. The overall cost is estimated to be £13 billion, however the estimated savings are expected to be £19 billion. So even after the investment of installing smart meters for everyone, there should be a national saving of £6 billion by 2034. (Updated: 2019-12-22)

How much is this all costing?

The total cost is estimated to be £13 billion, however the estimated savings are expected to be £19 billion. So even after the investment of installing smart meters for everyone, there should be a national saving of £6 billion by 2034. See this government document for more details Smart Meter Rollout Cost-Benefit Analysis. (Updated: 2019-12-22)

How much can I save on energy costs every year?

The average household can expect to see savings improve from an additional cost of £11 in 2018 to annual savings of £36 by 2034. (Updated: 2019-12-22)
