Givenergy panels and battery had been offline for a couple of months after various changes by Givenergy to their app etc. Ron did a fantastic job of sorting it out - got things up and running almost immediately, followed by some fine tuning to get things fully configured. What a legend - great service, great comms, great result.

Our 3 year old GivEnergy batteries froze. They were showing 0% on the app, but they were fully charged. Some how Ron took over our inverter and remotely cured the problem. We live in King’s Lynn, he is in Leeds I believe. Very grateful.

Absolutely fantastic experience, after months of being fobbed off with rubbish from the installer Ronald fixed my issues in a few hours, his attention to detail and his tenacity was amazing, not only did he go above and beyond but did not ask for payment i had to ask him how to pay. If you need a solar fix this company is brilliant

I received a prompt response and excellent technical support for the remote diagnosis (Oxfordshire) and resolution of my GivEnergy EMS configuration. My GivEnergy issue involved a single inverter and battery that had a loss of calibration, a critical low voltage drop. It needed a recovery and re-calibration, and was supported via email into yesterday evening being resolved within 24 hours. Ron demonstrated a very high level of knowledge and experience in the intricacies of a GivEnergy EMS configuration, even surpassing the understanding of GivEnergy itself when it was still operational. I have already recommended their services to a neighbour as I’d be happy to use their services again based on the fair pricing and the quality of their support.

What an absolute star. Ron went well beyond what i would have hoped for. His attention to detail was incredible, even making good the work of others.

Fantastic support. We have a Givenergy system where one of our batteries was not working. Ronald successfully helped us get it back up. His perseverance was amazing….and it shows what REAL customer service means. Can’t thank you enough Ron!

Takeover pricing

Baseline audit + handover
from £995

One-off onboarding fee. Includes on-site audit, documentation recovery, monitoring transfer, written baseline report. (GivEnergy: the current owner transfers the account in the app.)

Larger / medium system
from £995

For 50–150 kW commercial systems where the audit needs a full day on-site and more involved documentation work.

Ongoing care
No-fix-no-fee

After handover, fault response uses the standard rate-card — free remote triage, from £395 on-site callout. No locked-in retainer.

When you need a system takeover
Previous installer gone bust

The most common takeover scenario. Monitoring locked, no warranty contact, orphaned documentation. We handle the full recovery: documentation rebuild, monitoring access transfer (not GivEnergy), and a clean technical baseline.

Switching maintenance provider

Current O&M arrangement is too expensive, too slow, or too commercially conflicted. We can baseline the system while your current contract is still active — no gap in coverage during the transition.

Building acquisition / new lease

You've just bought or leased a commercial property with existing solar. You need to know what condition it's in, who looks after it, and what the maintenance commitments are. The takeover handover gives you a clear technical and contractual reset.

No existing arrangement

System was installed and then forgotten about — common with FIT-era commercial installs where the installer never offered ongoing maintenance. We build the maintenance regime from scratch.

Insurance / compliance requirement

Your insurer or facilities-management contract now requires named technical oversight on the solar installation. The takeover engagement gives you a documented commercial relationship with an independent provider — no manufacturer or installer conflicts.

Multi-site portfolio

Property management company with solar across multiple sites and inconsistent maintenance histories. We onboard the whole portfolio with a single baseline-audit cycle and consistent technical records across all sites.

How the takeover works — 6 steps

1
Free scoping call

You tell us where the system is, approximate size, brand if known, and why you're looking for a takeover. 15 minutes by phone or video. We confirm whether we can take it on and what the baseline-audit fee will be.

2
Written quote

Fixed-price baseline audit + handover scope, in writing. Larger systems get a bespoke scoping document. You commit before we schedule the on-site work.

3
On-site baseline audit

Full inspection: inverters, panels, cabling, isolators, battery storage where present, monitoring hardware, DNO connection. Components identified, wiring verified, faults catalogued. Half a day for small systems, a full day for larger.

4
Documentation recovery

We chase whatever paperwork we can: original commissioning certificates, MCS/RECC records, DNO connection agreements, FIT or SEG paperwork, warranty status. Where records are gone, we reconstruct from on-site evidence.

5
Monitoring handover

Portal access transferred to STS, alerting reconfigured to come to us, historical performance data exported and stored. If the original installer locked the portal, we work with the manufacturer to re-establish access. (GivEnergy: the current owner transfers the account in the app.)

6
Baseline report + ongoing care

Written baseline report covers system condition, all faults found, remediation quote (if any), and the documentation file. Then the system is under our care — ongoing fault response uses the standard no-fix-no-fee rate-card. No retainer.

FAQ

System takeover — frequently asked questions

A system takeover begins with a baseline audit — a full on-site inspection of your commercial solar system to assess current condition, identify faults, verify monitoring status, and recover or reconstruct documentation. We then remediate any immediate issues, configure monitoring under our care, and establish a documented baseline to measure future performance against. The baseline-audit fee is from £995; remedial work is quoted separately.
Yes. This is the single most common reason commercial clients contact us for a takeover. When the original installer is no longer trading, documentation is often missing, monitoring may have lapsed, and warranty claims become more difficult to pursue. We assess the system independently, recover what documentation we can, and establish a new technical baseline. We are not tied to any installer network — we take over any commercial solar system regardless of who installed it.
That depends on your existing contract terms. Review your current agreement for notice periods, termination clauses, and any handover obligations. We can conduct the baseline audit while your existing contract is still active — so there is no gap in coverage — and coordinate the transition to minimise disruption.
Missing documentation is common, particularly for older installations or where the original installer is no longer trading. Our engineers assess the system on site, identify all components, verify wiring configurations, check DNO connection agreements, and reconstruct a working system record. This baseline documentation becomes the technical reference for everything that follows.
The baseline audit is typically completed in a single site visit (half-day for small systems, full day for medium-to-large). Monitoring setup, documentation recovery, and any immediate fault remediation may take one to two weeks depending on system complexity and the availability of existing records. Once the baseline is established, the system is under our care immediately.
Yes. The baseline audit identifies all existing faults and underperformance. We provide a clear remediation plan with fixed pricing for any repair work needed before the system is fully under our care. You know exactly what condition the system is in and what it will cost to bring it up to standard. There is no obligation to carry out remediation through us — you can use the audit report independently if you prefer.
No-fix-no-fee remote diagnostic for any fault; same emergency-callout rates as the consumer side; written reports after every visit. We hold the documentation and monitoring access so when something happens, we already know the system. No locked-in retainer or surprise fees — same transparent rate-card as everything else on this site.
Baseline audit + documentation handover: from £995 one-off. Larger or multi-site systems quoted bespoke after a free scoping call. Any remedial work uncovered during the audit is quoted separately in writing — no surprise invoices. Ongoing fault response uses the same rate-card as the consumer site (free no-fix-no-fee remote, from £395 on-site callout).
