The cost of waiting: Why putting off smart sockets could cost you more than installing them
Your buildings could be wasting electricity right now. And while you're waiting for the next budget, the next approval or the next convenient opportunity, you're still paying for it.
Consider a smart socket deployment costing £1,500 and delivering £300 in monthly electricity savings. It would pay for itself in 5 months. Delay that investment by 6 months and you could miss £1,800 in savings — £300 more than the original deployment cost.
Whilst these figures are illustrative, not guaranteed outcomes, they highlight something that's often missing from energy efficiency business cases: the cost of doing nothing.
For sustainability, energy and estates managers planning their 2027 priorities, that cost merits prioritisation.
Plug-load waste: the energy cost hiding in plain sight
Most organisations have some visibility of their building's overall electricity consumption. What they don't necessarily know is how much of it comes from equipment left running unnecessarily.
Monitors, printers, bottle fridges, hot water taps, kitchen appliances and other plug-in appliances can continue consuming electricity long after a building has emptied.
Some equipment needs continuous power. Other devices could be switched off outside operating hours without affecting building operations.
The difficulty is identifying which is which.
Building-level energy monitoring doesn't always provide the detail needed to pinpoint waste at individual sockets. As a result, facilities teams can be managing major building systems effectively while unnecessary plug-load consumption continues unnoticed.
Smart sockets address this gap by combining appliance-level monitoring with automated control.
measurable.energy helps organisations identify wasted energy and automatically switch off suitable appliances when they're not needed.
This reduces reliance on employees remembering to turn devices off and gives energy and facilities teams greater control over this overlooked area of electricity use.
For organisations managing large buildings or multiple sites, the opportunity extends well beyond a handful of individual appliances.
Why the cost of waiting belongs in your business case
When assessing an energy efficiency investment, the conversation usually starts with three questions:
- What will it cost?
- How much will it save?
- How quickly will it pay back?
There's a fourth question worth asking.
What will it cost us if we wait?
Consider the earlier illustrative example:
After 12 months, deploying immediately would produce £2,100 in cumulative net savings. Delaying deployment by six months would produce just £300.
That's a £1,800 financial difference, despite both organisations making the same investment.
The calculation (based on measurable.energy's bank of appliance data) assumes savings begin immediately after deployment, remain constant and incur no ongoing or financing costs. Actual returns depend on site conditions, equipment usage and implementation requirements.
Nevertheless, it demonstrates why waiting should be treated as a financial decision rather than the default option.
When the potential cost of delaying exceeds the upfront investment, waiting deserves closer scrutiny.
For large estates, small inefficiencies can become expensive

The financial impact of plug-load waste varies between buildings, but the underlying problem is common across commercial estates.
Offices and education buildings
Monitors, printers, kitchen equipment and other devices can remain powered during evenings, weekends and holidays. Where those devices don't require continuous power, automated switching offers an opportunity to reduce unnecessary consumption without adding to facilities teams' workloads. (St Peter's School generated 40% in energy savings.)
Hotels and leisure facilities
Operating hours and occupancy patterns can vary considerably. Understanding which equipment needs to remain powered, and when, can help identify avoidable electricity consumption without compromising essential services. Beer fridges alone can waste as much as £1,100 a year in energy when left on, for example.
Retail estates
A modest saving at one store may appear insignificant. Across dozens of stores, however, recurring inefficiencies add up to a more substantial financial opportunity. Delaying improvements allows that wasted consumption to continue across the portfolio.
Construction sites
Temporary offices and accommodation present a different challenge: the opportunity to save energy has a deadline.
If a construction project has three months remaining, savings not captured during that period cannot be recovered once the site closes. Yet smart sockets installed in temporary accommodation can deliver payback in just 3 months.
The carbon cost matters too
For sustainability teams, reducing wasted energy directly lowers carbon emissions, contributing towards carbon reduction objectives.
This matters particularly as another reporting year draws to a close.
A project implemented in 2027 cannot retrospectively reduce electricity consumed during 2026. There is still time this calendar year to achieve carbon reductions by cutting wasted energy use.
And while future energy efficiency projects demonstrate intent, sustainability teams increasingly need to drive more immediate impact to demonstrate what has actually changed.
Smart sockets provide a faster opportunity to connect operational action with measurable energy reductions — in months rather than years.
There are benefits for each:
- Sustainability teams: Evidence of electricity reductions that can support emissions reporting.
- Energy managers: Greater visibility of plug-load consumption and opportunities to reduce unnecessary demand.
- Estates and facilities teams: Automated control of suitable equipment without relying on manual switching.
The value lies in being able to measure the opportunity, implement appropriate controls and demonstrate the results.
Don't wait for the next budget cycle to establish the numbers
Budget constraints, operational priorities and procurement requirements are legitimate reasons to scrutinise an investment.
But there's a difference between deciding a project doesn't justify the expenditure and delaying it because the potential return hasn't been established.
If the financial case is uncertain, the next step should be to gather better evidence.
A 28-day 'try-before-you-buy' trial with measurable.energy gives organisations an opportunity to measure plug-load consumption and identify where real savings can be made in their own environment.
These findings can help build a site-specific business case covering expected savings, deployment costs, payback and the implications of further delay.
That information gives sustainability leads and energy managers evidence to support carbon reduction plans and provides Finance with a clearer business case for investment.
Before you defer until 2027, calculate what waiting could cost
There will always be competing priorities for capital and management time. Not every energy efficiency project will warrant immediate investment.
But if unnecessary plug-load consumption is costing your organisation money, delaying action has consequences too.
The sensible approach is to evaluate both sides of the decision: what implementation will cost and what potential savings could be lost by waiting.
Before you move smart sockets into next year's budget, establish what another three or six months of unnecessary electricity consumption could cost your organisation.
