EV Charger & Solar Panel Installation in the Chilterns
Chiltern Energy Group installs EV chargers, solar panels, battery storage and air source heat pumps for homeowners across the Chilterns. Every installation starts with a free in-person site survey at your property.
Our NAPIT-qualified engineers cover Amersham, Chesham, Beaconsfield, Great Missenden, High Wycombe, and surrounding Chilterns villages.
Mon–Sat 08:00–19:00. Site surveys within 10 working days.

How does having a home EV charger change your daily routine?
A 7kW home charger charges your car overnight, every night. No queuing, no adaptor cables, no expensive rapid charger costs. We install NAPIT-certified EV chargers across the Chilterns from £899. Eligible properties pay from £549 after the OZEV grant — we handle the paperwork.
- NAPIT-certified installation: Part P compliant
- OZEV grant processing included
- In-person survey before any work is agreed
- From £899 installed (from £549 with grant)

How can solar panels reduce your electricity bills?
A well-designed solar system cuts most Chilterns household electricity bills by 40 to 60 percent. We design every system for your specific roof orientation, your actual usage, and your budget. From £4,995 installed (4kWp system). No hard sell, no generic online quotes.
- Smart Export Guarantee eligible installation
- In-person roof survey and honest yield estimates
- Battery-ready inverter options available
- From £4,995 installed (4kWp system)

How does home battery storage save you money?
Charge your battery on cheap overnight tariffs and use it during peak hours. If you already have solar, a battery means the electricity you generate at noon is available when you need it at 7pm. We size the right battery for your actual usage at a real in-person survey. From £3,495 installed.
- Compatible with most existing solar inverters
- Charge on Octopus Go and similar overnight tariffs
- Typical savings: £300 to £600 per year
- From £3,495 installed (5 to 7kWh system)

Why choose an air source heat pump over a gas boiler?
An air source heat pump delivers 3 to 4 units of heat for every unit of electricity consumed. For eligible properties, the Boiler Upgrade Scheme covers £7,500 off the installation cost. We check suitability honestly at the survey and tell you upfront if it is not right for your property. From £10,495 installed.
- Boiler Upgrade Scheme grant: £7,500 off
- Honest suitability assessment at every survey
- BUS grant of £7,500 handled by us
- From £10,495 installed (from £2,995 with BUS grant)

What makes us different from the national installers?
National companies make you upload photos, measure your own cable runs, and assess your own fuseboard. When something goes wrong post-install, you wait weeks. We work differently.
We come to you
Our engineer visits your property before any work is agreed. Real survey, real quote, fixed price on the day.
NAPIT-qualified, not a call centre
When you call 01494 977298, you speak to us, not a booking agent. Our engineer carries out the survey and the installation.
Fixed prices, no surprises
What we quote is what you pay. If anything changes (such as a consumer unit needing work), we tell you before we start, not after.
6-month post-install support
If anything is not right after installation, call us. We come back within days. Being local is the whole point.
What do you need to know about electric cars before buying?
An independent guide from Which? covering what owning an EV really costs, how home charging works, and what to think about before you buy.

“The engineer visited on Tuesday, assessed the whole job, and gave me a fixed price. No surprises. Installation was done Thursday, took about 3 hours. The charger works perfectly and the OZEV grant paperwork was handled for us. Would recommend.”
“We had quotes from two other companies who both sent forms to fill in online. Chiltern Energy Group came out within a week, assessed our roof properly, and gave us realistic generation numbers. The install was smooth and they explained everything clearly.”
“Martin was upfront about pricing from the first call. The in-person survey made a real difference. They spotted that our fuseboard needed a small upgrade, which other quotes had missed. Price was still fair and the installation was clean and professional.”
