GivEnergy Repairs & Support in Bristol

Bristol has 33 conservation areas by the council's own count, and 34 entries on the national planning register. That gap matters less than where the boundary actually falls, because the boundaries are drawn street by street. Bedminster's conservation area, for example, was defined on street layout and built fabric extant before the 1880 Ordnance Survey map, and the appraisal states that post-1880s streets are not included. So two houses on adjoining Bedminster streets can sit on opposite sides of the line. We check the address, not the district name.

The practical answer for most Bristol roofs is reassuring. Roof-mounted solar on a house in a conservation area is permitted development under the GPDO 2015, Schedule 2, Part 14, Class A, provided the equipment protrudes no more than 0.2 metres beyond the roof slope and sits no higher than the highest part of the roof, chimneys excluded. Only a wall fronting a highway is excluded by conservation-area status; there is no restriction on a roof slope facing the road. Bristol City Council says the same on its own solar planning page.

Bristol has 16 Article 4 Directions on the register. Nine remove only the C3 to C4 HMO change-of-use right, and the remaining seven remove boundary, enclosure and alteration rights, including front garden walls, fences, gates and hardstandings in Cotham and Redland, means of enclosure at Henleaze, Grove Wood and Blackberry Hill, external alterations to named properties in Clifton Village, and alterations and boundary treatments at Henbury and Sherrin Way. None of the 16 removes solar permitted development rights. Further HMO Article 4s take effect on 1 January 2027 in parts of Brislington, Frome Vale, Purdown, Southmead and Horfield, St George and Westbury Park, again change-of-use only.

Three address-level checks change the answer:

• Flat roof in a conservation area. Since December 2023 a flat-roof array on article 2(3) land, which includes conservation areas, needs a prior-approval application to the council on appearance before work begins. Bristol's own solar page does not mention this.
• Listed building. Class A excludes it. Grade II and II* listed residential property in the Clifton Conservation Area is the exception: a Local Listed Building Consent Order made on 2 July 2025, for a term running 2025 to 2030, grants the listed building consent, with conditions including no panels on a roof slope facing a highway and written council approval of position, size, fixing, colour, finish and any roof strengthening before works start.
• Over the city boundary. Bath, in Bath and North East Somerset, is a World Heritage Site in its entirety, so the wall-fronting-a-highway bar applies across the city. North Somerset, a separate authority, carries 38 Article 4 Directions, three of which restrict roofing or roof lighting, at Clevedon, Nailsea and Weston-super-Mare. All three pre-date 1995 and the register entries are summaries of scanned originals, so the original wording decides whether an array is caught.

Diagnostics and repairs on existing kit rarely touch any of this. It becomes relevant when a fault forces panels off the roof or an array to be relocated, and it is cheaper to know before the scaffold is priced than after.

GivEnergy Ltd entered administration on 9 April 2026. For a Bristol owner with a Gen 1, Gen 2, Gen 3 or All in One installed, the practical effect is narrow but permanent: the manufacturer warranty is no longer honoured. There is no longer a factory RMA route, no free replacement inverter, and no manufacturer engineer to escalate to. If your installer has also closed, there is nobody left in the original chain.

What did not change is the hardware. A GivEnergy inverter and battery run on firmware held locally on the unit. They keep charging, discharging and exporting on the settings already written to them. A system that was working on 8 April was still working on 10 April, and systems installed years before administration are still cycling now. The failure mode to plan for is not a sudden shutdown; it is that when something does go wrong, the old support path is closed.

So who supports it now? In practice, three groups:

• Independent engineers who can read the fault, work with the local interface and the physical hardware, and repair or replace at component and unit level. That is what we do.
• Your original installer, if they are still trading. Worth a call first, particularly if any workmanship guarantee they gave you was their own rather than the manufacturer’s.
• Nobody, for anything that depended on GivEnergy Ltd’s own authorisation, such as a warranty claim. That is the honest answer, and it is why settings and firmware on the unit in front of you now matter more than they did.

One Bristol-specific point. If your system runs an export limitation scheme agreed with National Grid Electricity Distribution (NGED), formerly Western Power Distribution, those settings are locked. NGED states they cannot be altered by the customer and may only be changed with the written agreement of the DNO. Administration does not lift that. Any reconfiguration touching your export limit still goes through NGED.

Our remote diagnostic is free. If we fix the fault remotely, it is £125. No fix, no fee.

Every job starts the same way: a symptom, not a diagnosis. Most of the GivEnergy faults we are asked about in Bristol fall into a handful of families, and most of them are identifiable before anyone climbs a ladder.

• Battery not charging or not discharging. Usually a charge/discharge schedule that has silently reverted, an AC charge slot left enabled from an old tariff, or a state-of-charge floor set higher than the owner realises. Occasionally it is a genuine cell or BMS fault.
• Portal or app showing offline. The inverter is normally running fine; the dongle has lost the router. Common causes are a broadband change, a new router pushing a different Wi-Fi channel or band, or a dongle that has dropped its stored credentials. While the data link is down, the system usually keeps running, so check the inverter's own screen. If the dongle won't rejoin your WiFi, we can set it up on site, from £195.
• BMS comms faults between inverter and battery (BMS Comm Fail). Seen as a battery that vanishes from the portal, reports zero capacity, or refuses to come out of standby. Address settings on stacked packs and the data lead itself are the usual suspects.
• Red status light or a persistent alarm code. Grid voltage and frequency excursions, insulation resistance, and over-temperature all present the same way on the front panel. The code and the event log tell us which, and whether it is the inverter or the supply.
• EPS not working in a power cut. A backup circuit that was never commissioned properly, an EPS setting disabled after a firmware update, or a changeover that has never been tested since the day it went in.
• Firmware. We don't advise running updates from the GivEnergy portal or app. Where an update fixes a problem you actually have, we do it manually, on a callout or by talking you or your electrician through it remotely. How we update GivEnergy firmware →
• CT clamp faults. Reversed orientation, the wrong cable clamped, or a clamp that has worked loose in the meter cupboard. The signature is import and export readings that look backwards, or a battery that charges from the grid when it should be soaking up solar.

Remote first: most of the above is solved without a site visit. Where a visit is needed, we have an engineer covering the Bristol area, subject to availability. Tell us the symptom and what the app shows, and we will start there. The same arrangement covers the south east from a separate engineer, so if you have landed here from the wrong side of the country, see GivEnergy support in Kent.

Remote first. Most GivEnergy faults we take on in Bristol are resolved without anyone going up a ladder: firmware mismatches between inverter and battery, portal account problems, a CT clamp reading in the wrong direction, charge and discharge schedules that were never rebuilt after an update, and packs that have drifted out of balance and need a controlled recalibration. We pull the readings, work the fault through with you, and tell you plainly what we find.

The remote diagnostic is free. If the fault is fixed remotely, the charge is £125. If it is not, you pay nothing. No fix, no fee. That is the whole of our remote pricing, with no call-out fee bolted on to it.

Some work cannot be done down a wire. We attend site for:

• failed grid relays and internal relay faults that need the inverter opened
• comms faults between inverter, battery and Gateway, including damaged cable runs
• BMS boards, pack faults and module replacement inside a stack
• DC isolators, at the inverter and on the roof, which are a routine water-ingress point on older installs
• WiFi setup, when the dongle won't rejoin your WiFi, from £195

On-site availability, stated honestly: cover for the Bristol area depends on an engineer being free at the time. There is no permanently staffed Bristol depot and no guaranteed same-day attendance. We tell you at the point of booking whether a visit can be covered and when, rather than holding a slot and moving it later.

Two local points to settle before a visit. Scaffolding that stands on the footway or the carriageway needs a Bristol City Council licence under section 169 of the Highways Act 1980, and the council normally accepts applications only from scaffolding companies, at least three working days before the scaffold goes up. Clifton, Hotwells, Cotham, Redland and Georgian Bedminster terraces sit on the back edge of the footway, so settle where a scaffold would stand before you book one. Second, if an export limit has to change as part of a repair, the customer limitation scheme settings may only be altered with the written agreement of National Grid Electricity Distribution, formerly Western Power Distribution.

Configuration is the work most often mistaken for a fault. A battery that never fills overnight, empties by teatime, or quietly imports from the grid to charge itself is usually running a schedule written for a tariff or an occupancy pattern that no longer applies. That is a settings problem, not a hardware problem, and it is the kind of work done down a wire. The remote diagnostic is free. If we fix it remotely, the charge is £125. No fix, no fee.

Common configuration jobs:

• Charge schedules and tariff optimisation. Rebuilding charge and discharge windows around a time-of-use import tariff, so the battery fills in the cheap hours and still holds enough capacity for the evening peak rather than dumping it at midday.
• CT clamp direction. A clamp fitted the wrong way round, or on the wrong side of the meter tails, makes the inverter read import as export. The symptom owners notice is a battery charging hard from the grid on a sunny afternoon, or an app that shows the house exporting at the moment it is actually drawing from the grid.
• EPS enable. Backup power only appears in an outage if a dedicated EPS circuit and changeover arrangement were wired in when the system went in. Where they were not, no setting will bring it to life, and we will tell you that rather than sell you a visit.
• Local control and the WiFi dongle. Signal is the usual culprit. Bristol City Council's own Cotham and Redland appraisal records that Pennant and Brandon Hill stone predominate there, and an inverter in a garage or utility room behind walls of it will often fail to hold a link to a router two floors up. Moving the dongle, adding a mesh point or going wired resolves more of these than a replacement dongle does. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting. If the signal doesn't reach, a WiFi extender is an extra £75, and we carry them with us.

Since GivEnergy Ltd entered administration on 9 April 2026, the manufacturer warranty is no longer honoured. The hardware keeps running on its local firmware, and the settings remain yours to change. One does not: if the system was connected under a customer export limitation scheme, National Grid Electricity Distribution, formerly Western Power Distribution and the network operator for Bristol, states that those settings cannot be altered by the customer and may only be changed with the operator's written agreement. We reconfigure around that limit, and we do not quietly move it.

Bristol's roofs pull in three directions. Roughly three in ten of the city's dwellings pre-date 1919 on the Valuation Office Agency's count, and in Cotham, Redland and Clifton that share rises above eight in ten. Clifton and Hotwells add Georgian and Victorian terraces where the council's own conservation area appraisal records "natural slate; clay double-Roman tile, brick chimney stacks with clay pots", and where some roofs are the traditional butterfly form screened by a front parapet. The post-war estates at Withywood, Lawrence Weston and Highridge, where six or seven dwellings in ten date from 1945 to 1964, are a different animal again. What fails on each is different, and it is almost never the panel.

The recurring faults we see on GivEnergy-equipped systems in older Bristol housing are mechanical rather than electronic:

• Mid and end clamps backed off or over-tightened. Under-torqued clamps let a panel creep down the rail and load the next one; over-torqued ones dimple the frame and start a slow crack in the laminate.
• Rail brackets landed on a slate rather than into the rafter. On a Victorian slate roof that shows up as a hairline lift and, later, a damp patch on a bedroom ceiling.
• MC4 connectors mated across brands, or crimped in the rain. A high-resistance joint runs hot, drops string voltage and reads at the inverter as an underperforming array rather than a connector fault.
• DC cable resting on a slate edge or dragged through a valley gutter. On a butterfly roof the valley and its outlets are where leaks start after any roof work, and abraded insulation there is a fault we trace regularly on Clifton terraces.

Access is the other half of the story. Terraces in Clifton, Cotham, Redland and Georgian Bedminster sit on the back edge of the footway, so a scaffold usually needs a highway licence from Bristol City Council under Section 169 of the Highways Act 1980. The council normally accepts applications only from the scaffolding company, at least three working days ahead, and its fee from 1 April 2026 is £90 for up to a month and £214 for up to three. That is why we diagnose remotely first. The remote diagnostic is free, most GivEnergy faults are settled over the wire, and £125 applies only if we fix it that way. No fix, no fee. We put steel up only when the fault is genuinely on the roof.

Bristol's distribution network operator is National Grid Electricity Distribution, or NGED, which runs the South West licence area (formerly Western Power Distribution, rebranded on 21 September 2022). The South West area runs from Bristol and Bath down the peninsula to Land's End, serving around 1.4 million customers. NGED is the body your installer notified, or applied to, when the inverter and battery were connected, and it is the body you or an engineer deals with when anything about the export side of the system changes.

Two routes exist. EREC G98 covers generation up to 16 A per phase, the equivalent of 3.68 kW on a single-phase supply, and works as connect-then-notify: the installer notifies NGED within 28 days of commissioning. Anything above that threshold falls under EREC G99, which is apply-before-connect. The point that is often missed: battery storage follows the G99 route, even where the panels alone would have been G98. NGED's own guidance states that an application for storage should follow the G99 generation application process.

Where the installer has folded, the practical problem is paperwork rather than hardware. Before we touch a system we ask what you can find:

• Any G98 notification or G99 application reference, and NGED's response letter or offer.
• Your MPAN, from an electricity bill.
• The inverter and battery model and serial numbers, plus the commissioning date.
• Any export limitation paperwork. NGED runs a Customer Limitation Scheme as two forms, an application before installation and a commissioning form within 28 days after.

If none of it survives, that is not a dead end. The notification or application was made to NGED, so NGED is where to start: general enquiries are on 0800 096 3080, Monday to Friday, 8am to 5pm.

One warning worth stating plainly. Where an export limit has been set under NGED's Customer Limitation Scheme, those settings are locked: NGED states they cannot be altered by the customer and may only be changed with the written agreement of the DNO. If a reconfiguration would move your export limit, that is a conversation with NGED first, not a setting to change in the app.

An installer going under does not switch your system off. The panels keep generating, the inverter runs on the firmware already loaded on it, and the battery holds whatever charge and discharge schedule was last saved to it. Your grid connection is unaffected as well: the G98 notification or G99 application made when the system went in was made to your network operator, National Grid Electricity Distribution, formerly Western Power Distribution, so that record sits with them rather than with the installer. GivEnergy Ltd entered administration on 9 April 2026, so the manufacturer warranty is no longer honoured either, yet the hardware carries on regardless. What you have actually lost is the workmanship warranty and the person who held your commissioning settings.

We will be straight about local failures. We have found no publicly evidenced collapse of a Bristol-headquartered solar installer, so we are not going to name one. The nearest documented South West case is Green Energy Together Limited, company number 09750103, which fitted solar and battery storage for householders under the council-backed Solar Together Devon scheme. Companies House records a creditors' voluntary liquidation commencing 6 July 2023 and a compulsory winding up commencing 20 December 2023. Devon rather than Bristol, but the position owners were left in is exactly the one we pick up.

Before you contact anyone, gather what you can find:

• Inverter and battery model and serial numbers, photographed from the labels.
• The electrical installation certificate and any commissioning paperwork.
• Your MCS certificate, if the original installer issued one, since an export tariff supplier may ask for it.
• The DNO reference for the original G98 or G99 notification, plus any export limitation paperwork.
• Monitoring app login details and the email address the account was opened with.
• Recent generation and export figures, or a screenshot of the event log.

Then book the remote diagnostic. It is free. Most GivEnergy faults on an orphaned system come down to settings, and we reach those without a van on your street. If we fix it remotely, the charge is £125. No fix, no fee. Where the work needs hands on the roof or at the consumer unit, on-site cover for the Bristol area depends on an engineer being available, so we will tell you when we can realistically attend rather than promise a slot we cannot hold. One caution: export limitation settings are locked and may only be changed with the DNO's written agreement, so we will not raise a limit quietly to make a fault disappear.

The monitoring account is separate from the repair. We do not handle GivEnergy account transfers, because the owner can do them in the app. If your installer has gone or cannot help, another installer can request access at givenergy.cloud/temporary-access. The account owner approves the request, and that installer can then help as the original could. Monitoring transfer guide →

We work on the GivEnergy range in Bristol and the surrounding BS postcodes, from the first-generation hybrids through to the three-phase units. Most of what follows is diagnosed remotely before anyone gets in a van.

• Gen 1, Gen 2 and Gen 3 hybrid inverters — no-charge and no-discharge faults, BMS communication loss, insulation-resistance trips, and firmware version mismatches between inverter and battery pack that show as charge or discharge errors.
• AC-coupled inverters retrofitted alongside an existing PV string inverter, where CT clamp placement and orientation are the usual cause of a system that charges from the grid when it should be taking solar.
• All-in-One units, including cases where the unit's Modbus interface is tied up at start-up and monitoring then reads flat or all-zero on a system that is in fact running.
• GivBat and the wider battery range, stacked and single-module, covering pack imbalance, cells dropping out of the string, and capacity that has quietly fallen away.
• EV charger faults: failed charge starts, solar-matching that never engages, and units that have lost their link to the inverter.
• Gateway and back-up circuits, where a unit fails to island cleanly during a cut, or the protected circuits stay dead when they should carry.
• EMS installations coordinating multiple inverters on one site.
• Three-phase systems, including phase-allocation problems that show as odd import readings on one leg.

GivEnergy Ltd entered administration on 9 April 2026, so the manufacturer warranty is no longer honoured. The hardware itself keeps running on the firmware already loaded, and it stays repairable. That is the work: fault-finding, repair, component replacement and reconfiguration on kit that no longer has a manufacturer behind it.

One point on export settings. Bristol sits in the National Grid Electricity Distribution (formerly Western Power Distribution) area, and if your system runs a Customer Limitation Scheme, NGED is clear that the settings cannot be altered by the customer and may only be changed with the written agreement of the DNO. We will tell you when a change you want falls into that category rather than quietly making it.

The remote diagnostic is free. £125 applies only if we fix the fault remotely: no fix, no fee. On-site cover for the Bristol area depends on an engineer being available, so a visit is arranged around that and reserved for work that cannot be done down a wire.
