New Build Homes and EV Chargers: What You Get and What to Upgrade (2026)

What the Law Requires

Since June 2022, Part S of the Building Regulations in England requires every new home with an associated parking space to include an EV charger. The minimum specification is:

• 7 kW minimum power output
• Smart charging capable (as defined by the Electric Vehicles (Smart Charge Points) Regulations 2021)
• Universal socket (untethered Type 2) or tethered cable with a Type 2 connector

For larger residential developments with more than 10 parking spaces, at least one space must have a charger and 20% of remaining spaces must have cable routes (ducting and wiring ready for future charger installation).

There's a cost exemption: if the charger installation would cost more than £3,600 per charge point, the developer can install cable routes instead of a full charger. In practice, this exemption rarely applies to standard new build houses.

Important: These rules apply to England only. Scotland has similar (but not identical) requirements under the Building (Scotland) Amendment Regulations 2021. Wales and Northern Ireland do not currently mandate EV chargers in new builds — though cable routes may still be installed by forward-thinking developers.

What Developers Actually Install

Here's where expectation meets reality. The regulation says "7 kW smart charger" — but that's a minimum specification, not a quality guarantee. In practice, most volume housebuilders install the cheapest compliant charger they can source in bulk. Common choices include:

• Rolec WallPod or Rolec EVO — basic 7 kW untethered units
• Pod Point Solo — functional but feature-limited
• Project EV Pro — budget-friendly compliant unit
• BG SyncEV — basic smart charger meeting minimum spec

These chargers are perfectly safe and legally compliant. They will charge your EV at 7 kW. But they typically lack the features that make the best chargers genuinely useful:

The biggest practical issue with most developer-installed chargers is the lack of a tethered cable. An untethered charger means you need to carry your own Type 2 cable, connect it to the charger, and then connect it to your car every time you charge. A tethered charger has the cable permanently attached — you just grab it and plug in, like filling up with petrol. For daily home use, tethered is significantly more convenient.

Should You Keep or Upgrade?

Keep Your Developer Charger If:

• You don't have an EV yet — the charger is there, it works, and there's no point upgrading until you know what features you actually want.
• You're on a standard electricity tariff — without a smart tariff, the smart features of a premium charger don't save you any money. The developer charger will charge at the same speed as any other 7 kW unit.
• Budget is tight — the charger charges your car. That's its job, and it does it. Everything else is a nice-to-have.

Upgrade Your Charger If:

• You're on (or switching to) a smart EV tariff — the Ohme Home Pro connecting directly to Octopus Intelligent Go to find the cheapest charging slots can save £400–600 per year. That pays for the upgrade within months. See our smart tariff charger guide.
• You have or are planning solar panels — developer chargers can't divert surplus solar energy. The Zappi GLO or Wallbox Pulsar Max can charge your car from free solar energy. See our solar charger guide.
• You want a tethered cable — this alone is reason enough for many people. The convenience of grab-and-plug vs. unpacking a cable every time is significant for daily use.
• The developer charger has limited warranty — if you're already out of warranty and want longer protection, upgrading to a 4–5 year warranty charger gives peace of mind.

What Does a Charger Upgrade Cost?

This is the good news. Since your new build already has the cable run from the consumer unit to the charger location, a charger swap is much simpler (and cheaper) than a fresh installation:

You're saving £300–700 compared to a fresh installation because the expensive infrastructure work is already done. Some chargers are near-direct replacements and can be swapped in under an hour.

Our Top Upgrade Picks for New Build Owners

Ohme Home Pro (£535) — Best Overall Upgrade

The Ohme is the upgrade that makes the most financial sense. Its direct integration with Octopus, OVO, and British Gas tariffs means it automatically finds the cheapest charging slots — something no developer-installed charger can do. If you switch to Octopus Intelligent Go at the same time, the tariff savings alone pay for the charger within 6–12 months. Available tethered with a 5m cable.

Tesla Wall Connector (£425) — Best Value Upgrade

The cheapest branded upgrade with a premium 7.3m tethered cable and 4-year warranty. No smart tariff integration, but seamless Tesla app control. Ideal for Tesla owners on a fixed off-peak tariff who want the simplest possible charging experience.

Zappi GLO (£599) — Best for Solar Homes

If your new build came with solar panels (increasingly common in 2026), the Zappi GLO is the charger that unlocks free daytime charging from your roof. Its CT clamp measures solar generation and diverts surplus energy to your car automatically. See our full solar charging guide.

What About the Wiring?

One advantage of new builds is that the wiring is fresh, correctly sized, and properly installed. When you upgrade the charger, the existing wiring should be fully compatible with any replacement 7 kW unit. Your installer will:

1. Isolate and disconnect the existing charger
2. Mount the new charger in the same location (or nearby if you prefer)
3. Connect to the existing wiring — the cable run and consumer unit circuit should need minimal or no modification
4. Test and commission the new charger, issue electrical certificates

The whole process typically takes 1–2 hours for a straightforward swap.

What to Check When You Move In

If you've just picked up the keys to a new build, here's your EV charger checklist:

1. Identify the charger model — check the brand and model on the unit and look up its specifications
2. Download the charger's app — register and connect to make sure the smart features work
3. Test a charge — plug in your EV and confirm it charges at the expected rate
4. Check the installation certificate — your developer should provide a BS 7671 electrical installation certificate for the charger circuit
5. Note the warranty period — register the warranty with the manufacturer (developers often don't do this for you)
6. Consider your tariff — even if you keep the charger, switching to an EV tariff will save you hundreds per year. See our tariff comparison guide.
