Inverter Replacement in Bradford

Bradford Council's conservation guidance names the local carboniferous sandstone of Bradford and Airedale, and the gritstone of Wharfedale, as the predominant building materials in the district's conservation areas, whatever the age of the building. Swapping an inverter here is still an electrical job, but on a solid-walled house the cable route, the roof access and the position the new unit can safely occupy are set by the fabric rather than by the box. We run Bradford out of Leeds, about 25 minutes away, with nothing added for travel.

Tell us the inverter brand and model, or photograph the data label. Add the fault symptoms and your BD postcode. If the walls are solid stone, the roof is stone slate, or the property sits in one of the district's conservation areas, say so: it shapes the survey and the mounting position, not the price.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

I had a red status light on my GivEnergy battery pack and Ron at Solar Tech Support was a great help resolving the problem. He was able to do a remote diagnosis of the invertor BMS firmware and hardware and gave very quick practical and professional support. Thanks Rob

Bradford context

In Bradford, the building material decides half the job

Bradford grew where its raw materials were. The British Geological Survey's account of the Bradford map sheet records that coal seams, along with fireclays, ironstone and building stone, were the resources which controlled the location and subsequent growth of the urban area.

Roofs followed the same logic, then stopped. Sandstone slate began replacing thatch from the late 16th century and was used almost universally in the district until the railways arrived in the mid-19th century and cheaper Welsh and Westmorland slate could be brought in.

Elland Flags

Named by the BGS as the main source of the local sandstone used for walling, paving and cladding

33%

Of the district's 209,867 households are terraced; 36.7% semi-detached, 14.7% detached, 11.6% flats (Census 2021, TS044)

Two roofs

Stone slates persisted in some areas into the early 20th century, so imported slate and stone slate both survive here

That chronology is worth knowing before anyone books a scaffold. The two coverings come off and go back in different ways, and only one of them is native.

The walls matter more. In our experience solid stone with no cavity is the normal case in Bradford's older stock, and where you cannot casually chase or core through masonry, the wall decides where a replacement inverter can go.

Cable routes and roof-space entries planned around the masonry, not driven through it
A cellar, an understairs cupboard or the roof space usually beats an outside elevation
Footprint and ventilation clearance measured on site, never assumed from the old unit
Where the covering has to be disturbed, the method is specified before the quote is sent

None of that makes the job harder to price. It makes it impossible to price honestly without looking first.

Bradford brands

Inverters we replace most often in Bradford

Which brand is on the wall was decided by whoever was selling in the feed-in-tariff years. Where the replacement can go is decided by the building.

Bradford Council's 2013 housing market assessment profiled a City Central sub-area covering Bowling and Barkerend, Bradford Moor, City, Heaton, Manningham, Toller and Tong.

On the Valuation Office Agency 2011 figures it used, that sub-area ran 50% terraced and 22% flats against 38% and 15% for the district, with high levels of pre-1919 stock. Each brand below meets that stock differently.

Fronius / SMA

The quality end of the scheme-era fleet, and the units most likely to arrive with nobody behind them.

Mark Group is long gone, and in our experience plenty of the local firms from the same boom have stopped trading too, which leaves a lot of the Bradford systems we get called to with nobody left to ring.

The consequence here is dimensional. A current unit rarely shares the old one's footprint or its ventilation clearance, and on solid stone the fixings are not free to move. Mark Group system? Start here →

Solis / Growatt

The volume string brands of the same years, and the ones we are called out to most. Our working expectation on a feed-in-tariff array of this vintage is a modest single-string replacement matched to the panels already up there, not one of the larger inverters that come as standard on newer installs.

The consequence is sizing. We check the string, the DC voltage window and the cable already in the building, and put the result in writing before anyone orders a bigger box than the array can feed.

GivEnergy

In our experience this is the retrofit battery brand we meet most often across the district, bolted onto feed-in-tariff arrays. A good share of what looks like dead hardware is firmware, a CT clamp on the wrong conductor, or a comms fault, so we prove it before anyone buys a box.

The consequence is cable geometry. A hybrid wants a clamp at the incoming meter and a lead back to the inverter, and with no void to hide that run in, the meter position tends to pick the inverter position. A cellar usually solves it.

One catch if that cellar is unheated: lithium cells are not meant to take charge below freezing, so before we condemn a battery that stops accepting charge on the coldest mornings we check whether it is the cell temperature talking. Genuine failures go in at one fixed supplied-and-installed price. GivEnergy in Yorkshire →

SolarEdge / everything else

The optimiser systems we get called to sit on the awkward roofs: the ones that lose a corner to an adjoining roofline or a stack, where a plain string inverter was never going to hold up through the afternoon.

The consequence is access. A failed inverter is an indoor job and the panel-level hardware stays put. A failed optimiser is not, because reaching one means lifting the covering, and on a stone-slate roof that is a roofing operation rather than something to improvise from a ladder.

So we settle which it is remotely, before quoting. Sunsynk, Huawei, Enphase, Fox ESS and SolaX go the same way. Full service details →

Pricing

Inverter replacement pricing in Bradford

String inverter
From £995

Single-phase, 2–6 kW, all-in. The usual route for the district's feed-in-tariff fleet, matched to the array already up there rather than upsized for the sake of it.

Hybrid inverter
From £1,495

Replace a dead string unit with a battery-ready hybrid. Which network route the storage addition takes is confirmed before the price is fixed, not after. GivEnergy replacements come at one fixed supplied-and-installed price.

Three-phase / large
From £1,295

Anything from 8 kW up, and any three-phase unit, priced per system once the supply and the existing array have been checked. Full pricing details →

Each figure is inclusive: supply, decommission, install, commissioning, the Northern Powergrid submission and the written report.

Stone construction does not change the number. It changes the survey, because the cable route and the mounting position get settled before the van is loaded rather than worked out on the doorstep.

Conservation area or stone roof?

A roof with rules of its own

Bradford Council lists 60 conservation areas across the district. Four cover the city centre alone (City Centre, Cathedral Precinct, Goitside and Little Germany) and five carry the Manningham name (Apsley Crescent, Eldon Place, North Park Road, Southfield Square and St Paul's).

The rest reach out through Great Horton, Little Horton Green and Little Horton Lane, Heaton Estate, Clayton, Thornton, Queensbury, Idle and The Green, Eccleshill and Tong, with Saltaire and Wrose over towards Bingley and Shipley.

On an inverter job the designation is rarely the hard part. The covering is, and the council's repairs guidance is specific enough about it that the method belongs in a written quote rather than in a conversation on the day.

Stone slates re-fixed with oak, treated softwood or copper pegs, or copper nails, with stainless or galvanised nails in the structure
Slates never turned over: the council warns the underside is not the weathered face and can deteriorate rapidly once exposed
Sheathing checked for rot and projecting nails, replaced in solid timber of the same depth, never plywood or pressure-treated board
Diminishing courses kept on Welsh, Westmorland and Burlington slate, so the roof still reads right afterwards
Roof works planned — from £1,495

If the covering is coming off, the array comes off and goes back with it. That is also the sensible moment to deal with a tired inverter rather than scaffolding twice.

Which network operator gets the application

Bradford, Keighley and Cleckheaton all sit in the Northern Powergrid (Yorkshire) licence area, the same operator as Leeds, Halifax and Huddersfield. That is verified against the published DNO licence-area boundary dataset, last updated 6 May 2025, where the polygon covering these towns is labelled NPG (Yorkshire Electric).

The licensed operator is Northern Powergrid (Yorkshire) plc, MPAN distributor ID 23, which is the 23 we would expect at the front of the supply number on a Bradford bill.

The BD postcodes do not all follow suit. Northern Powergrid's postal-district layer, last updated 9 January 2024, lists 26 BD districts: BD1 to BD23, plus the non-geographic large-user codes BD97, BD98 and BD99.

Of the 27 districts in the BD area the only absentee is BD24. Settle, Giggleswick and Horton in Ribblesdale, along with the western edge of BD23 around Malham, fall inside the Electricity North West licence area, branded SP Electricity North West since August 2025.

A notification at that end of the BD area therefore goes to a different operator, on a different portal, than one in Bradford.

That layer also selects any district merely overlapping the boundary, so it shows overlap rather than proving the operator for every part of every district listed. We check the individual address against the Energy Networks Association operator lookup before anything is filed.

One thing not to read too much into

Northern Powergrid publishes red, amber and green heat maps giving what it describes as a high-level indication of how much capability its network has to take on new connections, substation by substation across its extra high voltage and high voltage network.

It also states that they give a general illustration of generation availability constraints only, cannot be relied upon to assess the terms of connection for specific premises, and that a full design study will be required before any connection offer can be made.

So the colour over your area is not an answer about your house.

FAQ

Inverter replacement in Bradford — common questions

The all-in figure for a single-phase string replacement here starts from £995, covering the new unit, safe removal of the old one, the install, commissioning, the network notification and a written report. A battery-ready hybrid starts from £1,495, three-phase and larger units from £1,295. We run Bradford out of our Leeds base, about 25 minutes away and inside standard coverage, so nothing is added for travel. If you are not certain the inverter is the failed part, the free remote diagnostic establishes that first, at no cost.
Very probably not, which is why we ask for the address before describing the job. Bradford Council's May 2023 ward profiles, built on Census 2021 data, record Bradford Moor with the highest percentage of terraced properties of the district's 30 wards, City with the highest percentage of flats, Eccleshill the highest percentage of semi-detached homes, Wharfedale the highest percentage of detached, and Baildon the lowest percentage of terraced. City ward, which takes in the University of Bradford and Bradford College, holds 8,215 households: 37.8% terraced, 35.7% flats, 2.7% detached. Roof access, loft depth and the choice of a ventilated position for the inverter all move with that mix, so a district average is a poor guide to any one street.
Bradford is served by Northern Powergrid (Yorkshire) plc, an active company registered in England and Wales under number 04112320 and named Yorkshire Electricity Distribution plc until 2011. Every BD-postcode substation site in Northern Powergrid published asset data sits under its Yorkshire area rather than its North East one, so that is where a Bradford application goes. Which route it takes is a capacity question rather than a consequence of the old unit having failed. ENA Engineering Recommendation G98 covers micro-generators with an aggregate registered capacity up to and including 16 A per phase, which is 3.68 kW single-phase and 11.04 kW on three phase; above that the EREC G99 process applies. Where one connection point holds more than one inverter inside that limit, G98 treats the installation as a single micro-generating plant, so a second inverter added beside an existing array counts alongside the first. The current issue is EREC G98 Issue 2, April 2026, and that threshold is unchanged from earlier issues.
For a micro-generator it is Northern Powergrid G98 Form B, which the installer completes and returns once the plant has been commissioned. It asks for the property MPAN or MPANs, the micro-generator manufacturer and its manufacturer reference number (which should be registered on the ENA Type Test Register), the date of installation, the registered capacity in kW broken down per phase, the location of the lockable isolation switch, and a signed installer declaration that the plant conforms to the requirements of EREC G98. The same form applies across the whole of Northern Powergrid licence area, Bradford BD postcodes included. We file it as part of the job and put a copy in your report.
All of the city and the wider metropolitan district, on the same pricing and lead times as anywhere else in standard coverage. Keighley, Bingley, Shipley, Saltaire, Baildon, Ilkley, Silsden, Steeton and Haworth in the north of the district; Queensbury, Thornton, Clayton, Idle, Eccleshill, Wrose and Tong around the edge of the city; Manningham, Heaton, Great Horton, Little Horton, Bradford Moor and Bowling and Barkerend inside it. The free remote diagnostic usually runs the same day you get in touch, and the swap itself is a half-day visit.
Replacing an inverter is not the part of a solar installation that rule was written for. Under the Town and Country Planning (General Permitted Development) (England) Order 2015, Schedule 2, Part 14, Class A, solar equipment on a dwellinghouse or block of flats is not permitted development where the land is in a conservation area or a World Heritage Site and the equipment goes on a wall which fronts a highway. Roof-mounted equipment is not caught by that paragraph. Our reading is that an inverter sited inside the building is not caught by it either, though we would confirm that with the council before relying on it. Other Class A limits still apply, and permitted development is ruled out separately on scheduled monuments and on buildings within the curtilage of a listed building. It is national law rather than a Bradford rule. The case worth checking properly is the one where the existing unit sits on an outside elevation, which we settle at survey.
