Part S compliant EV charging infrastructure designed in from the outset. Grid connections, feeder pillars, passive ducting, and smart charging for developments of all scales.
Every residential EV charging project follows a clear sequence. Here is exactly what happens at each stage.
Part S of the Building Regulations sets a baseline: every new dwelling with associated parking must have either a passive cable route (25-32mm conduit with draw wire) or an active 7kW charge point. In practice, local planning authorities frequently go further. Many councils now require an active 7kW charger at every parking space as a planning condition, and some require 22kW capability for larger spaces. USP reviews the specific planning consent and Part S requirements for your scheme before design commences, so the infrastructure meets both the regulatory minimum and any planning obligations.
A single 7kW charger roughly doubles the peak electrical demand of a new-build dwelling. For a 100-plot scheme with one charger per home, the theoretical unmanaged peak demand is 700kW on top of the base domestic load. In practice, DNO diversity modelling and smart charging demand-side response reduce the real coincident peak, but the load assessment must account for EV from the outset to size the grid connection correctly. USP prepares a full diversity-adjusted load model before submitting any application to the DNO or IDNO, ensuring the connection is sized for the actual EV-inclusive demand rather than the base domestic load alone.
For houses with individual parking spaces, the simplest approach is a dedicated 7kW circuit to each plot, either as a direct charger installation or as a fused spur ready for the future charger. For apartment schemes, individual circuits back to each flat meter are impractical. The standard solution is a feeder pillar in the car park supplying dedicated charging bays with sub-metering so residents are billed for their own consumption. For developments where immediate EV installation is not required but future demand is anticipated, passive ducting (25-32mm conduit with draw wire installed during civils) allows chargers to be added at minimal cost later without breaking ground again.
Smart charging allows the charge rate to be reduced automatically when overall demand is high, significantly reducing coincident peak and the required grid connection capacity. Any EV charger above 3.68kW on a single-phase supply, or above 11kW on a three-phase supply, requires DNO notification under Engineering Recommendation G99 or G100. For larger schemes with multiple chargers, a formal application rather than simple notification may be required. USP manages the full DNO notification and application process, ensures all chargers are G99/G100 compliant, and designs the smart charging system to work within the agreed Maximum Import Capacity.

I contacted USP and within minutes had a chat with Justin who described exactly how the job would be done and provided a comprehensive quote including labour and materials and was able to start the work in just 7 days. Justin and his team were brilliant and did an amazing job. I can highly recommend USP.
Jack and Joel were absolutely amazing this morning and really put themselves out to dig a hole without having to dig another hole in my drive. More work for them but one happy customer.
From the initial quote through to work completion, Justin and his work partner were a mix of professional, knowledgeable, good-humoured, and clear in all explained (I felt an instant ease to agree to the work). The work itself was excellent and they left the place immaculate!
George and Jack come out today to move a gas meter. It wasn't a straightforward job, but they both took time to talk me through what they were doing and what the next steps are. Very friendly and polite and thought about the needs of our family.
Jack and George are great.
Bang on time, completed the work perfectly, no issues. Left the meter really neatly finished. Jack and Joel were very courteous and did a great job.
George and Jack turned up and did a first class job, very friendly and professional. Great job lads.
Jack and Joel were brilliant. Very polite, worked to my highest expectations. Left the area as clean and tidy, as was possible. And explained every step of the process to me, answering any questions I had.
Fantastic work from Jack and Johl.
