A trusted partnership

Giulio did a great job on our electrical work. Listened to what I wanted, including changes to what I’d originally asked for, and was happy to do exactly as asked. Polite, professional, punctual, reliable and trustworthy. Very neat and tidy. Reasonable pricing. Would definitely engage again.

Wren Energy recently upgraded our system from a 5 kVA Victron MultiPlus to a 15 kVA Quattro and replaced the Pylontech batteries with 128 kWh Fogstar. Giulio understood our complex requirements, communicated well and worked with real attention to detail. The whole process from initial consultation to final commissioning ran smoothly. Highly recommended.

Complex bespoke project for a 3 phase house using 40 solar panels on 3 flat rooves. 2 large storage batteries providing more than enough electricity for all needs and much excess being sold back to the grid. Great consideration given to the aesthetics(panels & any wiring barely visible). Very controllable system using high quality Victron MPPT & inverters etc. Full data visible & adjustable on mobile phone & iPad. Delighted with the system.

We were told our old back boxes wouldn't fit new switches. Wren sorted it easily, wired the appliance, and thoroughly tested the circuits to ensure complete safety. Great service!

Wren walked us through the exact plan before starting the board swap. Solid, honest work from their in-house team without any contractor headaches or upselling.

Your house should work for you

You've already paid for your home; you shouldn't overpay to run it.

We consult with you to ensure that every feature improves your living standards without regrets for the next three decades.

Don't buy it if it isn't worth it. And if it is not worth it, we will be the first to tell you to keep your money.

1. Safety

2. Value

3. Comfort

4. Aesthetics

How we deliver

You get direct expertise and absolute ownership of the execution. Upgrading your home should not be a gamble.

End-to-end accountability

The engineer who surveys your home is the one who delivers the project. There is no disconnect between initial promise and final commissioning, meaning you never have to wonder who is in charge of the project.

Seamless coordination

Whilst we adhere to high engineering standards, your preferences matter. We map out with you cable routing and equipment location, and work with other trades to ensure a flawless, integrated finish.

Certification and aftercare

We hold our own NAPIT, MCS, and HIES accreditations and do not need third party sign-offs. You receive a handover file, an insurance-backed guarantee, and a direct line to whom built your system - not a call centre.
