Start with a repeatable week, not the nearest pin
An electric car can fit a life without home charging when you have practical access to compatible chargers and enough time to use them. Write down your normal week: commuting, shopping, parking and longer trips. Identify where charging can fit into time you already spend parked. A nearby map marker does not establish public access, operating hours, available bays or a connector your car can use. Visit the location and read the operator’s conditions before depending on it. Keep an alternative that does not rely on the same car park or opening hours.
Estimate how much energy you need to buy
Use weekly distance and realistic battery-side consumption rather than the advertised full-charge range. For an illustrative 250 km week at 18 kWh/100 km, the car uses 45 kWh from its battery. At an assumed 10% loss between billed energy and battery energy, that becomes 50 billed kWh. A hypothetical £0.60/kWh tariff costs £30 for that week, before any other fees. Those are calculation inputs, not a UK market average or a claim about a particular car. If your energy figure already includes charging losses at the meter, do not add them again.
Match charging time to the place you park
For a simplified AC example, adding 30 kWh to the battery with 7.4 kW drawn and an assumed 90% delivery efficiency takes about 4.5 hours: 30 ÷ (7.4 × 0.9). Use the lower supported power of the car and charger, with the correct electrical supply; a higher number on the station does not force the car to accept it. DC charging is not a constant-power calculation because power changes through the session. Use a realistic charging window and check the vehicle’s documented curve or a relevant charging-time estimate. Add time for getting there, connecting and any queue. A weekly plan that only works with every bay empty is fragile.
Compare membership with the energy you will actually buy
A discounted price can still cost more after the monthly fee. Divide the subscription fee by the price discount to find the eligible billed energy needed to break even. With invented prices of £8/month, £0.60/kWh PAYG and £0.45/kWh membership, break-even is about 53.3 eligible kWh each month. Charging at other networks does not help recover that fee unless those sessions qualify. Check roaming, minimum terms and cancellation conditions. A twelve-month average can hide quiet months when you pay the fee but hardly charge.
Treat workplace and shared-building access as conditional
Record who can use the charger, whether you can reserve a bay, its working hours and what happens if your employment or parking arrangement changes. Confirm building permissions and billing with the responsible operator; a socket or charger in a shared garage is not automatically yours to use. For rented property or communal parking, ask for the access and payment rules in writing. Workplace charging can be a useful part of the plan, but a second option matters if the site is closed or the charger is occupied.
Stress-test a week with higher demand
Repeat the plan with the consumption you expect in cold weather or on faster roads. Keep a realistic arrival reserve and avoid assuming every stop begins at zero charge or ends at full. Price a second public location and count any parking, idle or session fees separately. If the resulting weekly cost or time is uncomfortable, that is useful information before a purchase. This worksheet compares access and cost assumptions; it does not certify a location, predict live availability or tell you which vehicle to buy.
Your no-home-charging decision sheet
Fill this out using the sites you can actually use. The example is a planning pattern, not a location recommendation.
| Check | Evidence to collect | Fallback question |
|---|---|---|
| Regular stop | Compatible connector, access hours, price and parking rules | Where do I go if all bays are occupied? |
| Weekly energy | Distance × battery-side consumption, with a consistent loss boundary | Does a colder or busier week still fit? |
| Time available | Vehicle charging limit and usable parking time | Can I finish before the car park closes? |
| Monthly bill | Billed kWh, subscription and non-energy charges | What happens in a low-use month? |
| Access changes | Workplace or shared-parking eligibility | Can the plan survive losing this location? |
Turn the worksheet into a budget
In the tariff comparison calculator, set the home share to zero, enter your actual public price and add any membership you are considering. Compare the recurring cost with your monthly budget. Keep parking and time-based charges beside the result because the calculator does not include them. Then use the charging-time tool to check whether the sessions fit your routine.
Before you rely on the answer
- Have I checked at least one usable alternative in person?
- Is the vehicle compatible with the charging equipment I plan to use?
- Does the plan still work when energy use or waiting time increases?
