Energy is one of the biggest costs you can actually control in a commercial building. The bill lands every month, the rate moves in ways you can’t predict, and the pressure to cut both cost and carbon keeps rising; minimum energy efficiency standards for non-domestic buildings are already in place and set to tighten.
Non-domestic rented properties in England and Wales must currently meet a minimum EPC E rating. From 2031, buildings over 1,000 square metres will need to reach EPC B, where cost effective.
Most businesses answer this one job at a time: an LED upgrade this year, solar maybe next year, EV charging when a few drivers go electric. A commercial building energy upgrade planned as one programme almost always beats that approach, on cost and on disruption.
If you’d rather scope the whole thing at once, you can request a commercial energy upgrade quote and start from a single site visit.
Why a Combined Upgrade Beats 3 Separate Projects
Run LED, solar and EV charging as three separate projects and you pay for the same groundwork three times. Three site surveys, three sets of design fees, three separate decisions about your electrical supply, often made without reference to each other.
You also disrupt the building three times, which for a live site means three rounds of access, coordination and downtime.
Plan them as one programme and that overhead collapses. A single survey looks at the whole building. One electrical design accounts for all three loads from the start, so nothing has to be ripped out and redone when the next phase arrives.
You deal with one contractor and one point of contact, rather than briefing three, chasing three and reconciling three. The works can still be phased over time but the difference is that they’re designed together.
For a facilities or estates lead running a live site, fewer mobilisations and one accountable team is the practical win, before any of the energy savings are counted.
The 3 Pillars, and Why Order Matters
The order you tackle the three measures changes the economics. Cut demand first, then generate, then use what you generate. That’s why LED comes first; it shrinks the load that everything after it is sized against.
LED Lighting: The Fastest Payback
Lighting is the logical first move and usually the easiest to justify. It needs no roof space or grid capacity, and it cuts your building’s baseline electricity demand from day one.
Switching old fittings for commercial LED lighting and adding presence sensors and zoning, so lights run only where and when they’re needed, is among the most cost-effective energy efficiency upgrades available to a commercial building.
It also sets up what follows. Every kilowatt you take off the lighting load is a kilowatt your solar array no longer has to cover, which makes the solar that comes next smaller, cheaper and a better fit to your actual demand.
Solar PV and Battery Storage
With the load reduced, solar makes more sense. A smaller array now covers a higher share of your demand, which improves self-consumption and shortens payback, because the cheapest unit of solar is the one you use on site rather than export.
Commercial solar panel installations turn your roof into generation through the working day, when most commercial demand sits.
Battery storage is the natural partner. It holds the surplus your panels make at midday and releases it later, so less of your generation is wasted and less of your demand comes from the grid. If you’re weighing whether to add storage, our guide on how battery storage works with solar covers the trade-offs.
Sized against a reduced load, the generation step does more for less.
EV Charging, Built on the Same Supply
EV charging belongs in the same plan, not bolted on two years later.
The reason is electrical capacity. Commercial EV charger installation draws significant power, and adding chargers without checking the spare capacity in your supply is how businesses trigger an expensive upgrade or a long wait for the network operator.
Designed in from the start, the chargers share a supply that’s already been assessed for all three loads.
There’s an energy case too. Combining solar and EV charging means daytime generation, and stored surplus, can feed the chargers instead of buying that power from the grid. That’s where workplace and fleet charging starts to pay back rather than sit on the books as a cost.
How the 3 Work Together
This is the part that gets lost when the measures are bought separately.
LED cuts your demand, so a smaller solar array covers more of what’s left. The battery stores the solar you don’t use immediately. That stored and surplus energy then powers your EV charging, so the cheapest electricity on site goes into the vehicles before any grid power does. Each step makes the next one work harder.
The electrical design is what ties it together. One distribution strategy and one conversation with your network operator can cover the lighting, the generation, the storage and the charging, instead of revisiting your supply three times and paying for upgrades you could have planned around.
For larger organisations with ESOS obligations, a programme like this also produces the energy audit evidence and carbon data you need in one place, rather than assembling it from three separate contractors.
How to Sequence and Fund the Programme
A sensible running order over 12 to 24 months works for most buildings.
Do the electrical design once, up front, so every later phase drops into a supply and board layout that already expects it. Start with LED; the savings begin immediately and help fund what follows. Bring in solar and battery storage next, sized against the now-lower demand. Add EV charging onto the supply that was designed for it.
A phased approach spreads the capital, keeps disruption low and means each stage is informed by the one before.
On funding, the routes are much the same as for any major plant: buy outright and keep the full return, spread the cost with asset finance while still owning the kit, use an operating lease, or take a Power Purchase Agreement for the solar with no upfront cost. Each has a different effect on cash flow, ownership and the tax position, so it’s a conversation to have with your accountant and your installer together rather than a default.
The funding can be decided phase by phase without breaking the overall design.
How MD Govier Delivers a Full Energy Upgrade
Doing this as one programme only works if one team can actually deliver all of it.
MD Govier installs LED, solar, battery storage and EV charging, which means the survey, the electrical design and the phased delivery sit with a single accountable contractor. We visit the site and assess it before quoting, so the design is built around how your building actually runs.
The work is carried out by NICEIC-accredited engineers and planned around your operations, including phased or out-of-hours stages where a live site needs it. You get one point of contact across the whole programme.
Our work reducing electricity costs in commercial buildings shows the combined approach on a real site, with the savings to back it.
Start Planning Your Building’s Energy Upgrade
You don’t need to decide on all three measures today. You need one assessment of the building that looks at the whole picture and a plan that sequences the work to suit your site and your budget.
That’s a single conversation. Request a commercial energy upgrade quote and we’ll arrange a site visit.
