Solar panel removal and reinstallation in the UK is best budgeted as three main costs plus parts and waste, not one line on a roofer’s quote: access (scaffolding), panel handling (taking the array and rails off and refitting them), and electrical recommissioning (safe isolation, reconnection, testing and a certificate). For a typical 8 to 16 panel domestic array lifted so a roof can be repaired or replaced, the whole job usually lands in the high hundreds to low four figures, with scaffolding and labour the biggest movers. The exact number depends on your access, the size of the array and who owns the electrical work.
The reason most quotes go wrong is not the roofing. It is that a re-roof with panels on it needs a roofer and a competent solar electrician, and the two trades own different parts of the job. This guide sets out who does what, the safe order of work, and the paperwork that decides whether your export payments and warranties survive the lift.
How much does solar panel removal and reinstallation cost in the UK?
Plan for three main costs plus parts and waste. The figures in the table below are planning ranges to sanity-check quotes, not fixed prices, so get written quotes on your own property before you rely on them. Scaffolding and labour are the biggest movers, and access more than array size is what pushes a job to the top of the range.
What sits behind those ranges is your own property. The array size, roof height, whether the panels come back onto new mounting, and how much of the roof is being redone all move the figure, so two houses with the same panel count can price very differently.
| Cost bucket | What it covers | What moves the price | Rough planning figure |
|---|---|---|---|
| Access (scaffolding) | A guarded working platform for both trades, up and down once or held for the whole job | Number of elevations, roof height and shape, ground access, hire period | £500 to £1,200, more for complex or multi-elevation access |
| Panel handling | Removing panels and rails, storing them safely, refitting after the roof work | Number of panels, array layout, whether old fixings and flashings are reused or renewed | £300 to £900, a day or two of skilled labour |
| Electrical recommissioning | Safe isolation, disconnection, reconnection, testing and a certificate | Whether the same installer returns, system age, condition of cabling and connectors | £150 to £400 |
| Parts and waste | New roof anchors, flashings, seals, cable ties, and disposal of old material | Condition of the original mounting, roof covering type, how much is replaced | £100 to £300 |
As a worked example, a 12 panel array on a two-storey semi with straightforward access might see scaffolding around £600 to £900, panel handling around £400 to £800, recommissioning around £200 to £350, and parts and waste around £150, for a rough total in the region of £1,350 to £2,200. Complex access, a full re-roof, or renewed mounting pushes it higher. Treat this as a figure to test quotes against, not a quote for your own roof.
Timing feeds straight into the cost, because scaffold hire is charged by the period. Expect the panels off in a day, the roof work over several days depending on the job, then a day to refit, reconnect and test. Scaffolding is usually on hire for one to two weeks, so a job that drags between trades costs more than one that is coordinated tightly.
Some firms quote per panel for the handling rather than as a day rate. Either way, ask for access, panel handling and electrical recommissioning as separate lines, with parts and waste itemised, so you can compare one quote against another on the same scope.
One point that catches people out: refitting rarely reuses every original fixing. Roof anchors, flashings and seals are often renewed when the covering is disturbed, and old panel connectors are sometimes remade. That is good practice, not padding, but it belongs in the quote rather than appearing as an extra on the final invoice.
Who does what: the roofer and the solar electrician
This is the part broad price guides skip, and it is the part that decides whether the job goes smoothly. The roof covering is the roofer’s work. The array and everything electrical is the installer’s or a competent electrician’s work. Neither trade should be doing the other’s part.
| Task | Roofer | Solar installer / competent electrician |
|---|---|---|
| Safe isolation of the array (DC and AC) | No | Yes |
| Disconnecting and labelling cables | No | Yes |
| Lifting panels and removing rails | Sometimes, with the installer | Yes |
| Removing and refitting roof covering, battens, felt | Yes | No |
| New flashings and weatherproofing around mounts | Yes | With the installer on the mount detail |
| Refitting rails and panels | No | Yes |
| Reconnection, testing, recommissioning, certificate | No | Yes |
The interface between the panel mounts and the roof covering is the one place both trades touch. That is where water gets in months later if nobody was clearly responsible for the flashing detail. Before work starts, get a plain answer to one question: who is responsible for weatherproofing each roof anchor when the panels go back on? If the answer is vague, the job is not ready to book.
Someone has to hold the programme across the two trades. The tidiest arrangement is one contractor who project-manages the job and subcontracts the other trade, so a single party owns the timeline and the roof-to-mount detail. If you hire the roofer and the solar installer separately, agree in writing who coordinates the sequence and who is on site on the days the panels come off and go back.
Where possible, use the original installer to take the array off and put it back. They know the mounting system, they can keep the workmanship warranty intact, and the electrical recommissioning stays with the people who commissioned it first. If they are unavailable, any competent solar installer or electrician can do it, but the handover of documentation matters more, which is the next section.
The safe order of work for a re-roof with panels on it
The sequence protects the panels, the roof and the people on it. Getting the order wrong is how panels get scratched, connectors get stressed, or a roof sits open longer than it should. A workable order looks like this:
- Scaffold and edge protection go up first, sized for both trades and for handling full-size panels safely. Working at height on a sloping roof needs proper access under the Work at Height Regulations, not a ladder.
- The installer safely isolates the array, disconnects it, and labels the strings and cables so it goes back the same way.
- Panels come off and are stored flat and protected, out of the wind and off the ground. Rails and roof anchors come off after.
- The roofer completes the covering, including the areas that were under the array.
- New roof anchors and flashings go in, then the rails, then the panels, with the mounting-to-roof detail weatherproofed as agreed.
- The installer reconnects, tests, recommissions and issues the electrical certificate. Only then is the scaffold struck.
Coordinate the two trades so the roof is not left open around the panel line, and so the scaffold is held until the electrical recommissioning is signed off. A scaffold taken down before the final test means paying to put it back if anything needs correcting. If a long re-roof means the panels are down for weeks rather than days, agree where they are stored, keep them dry and supported off the ground, and check the product warranty does not exclude a spell in storage.
Document the system before anyone unbolts a panel
Documentation is the cheapest insurance on the whole job, and it is the part homeowners are best placed to insist on. A panel that comes back cracked, or a warranty claim refused because nobody can prove the array’s condition before the work, costs far more than the ten minutes of photographs it takes to prevent.
Before removal, record:
- Serial numbers of every panel and the inverter, photographed on the roof and against a written list, so the same hardware demonstrably goes back.
- Condition photographs of each panel front and back, the mounting, the cabling and the roof penetrations, dated.
- The original paperwork: the MCS certificate, the electrical installation certificate, the DNO connection confirmation, and your product and workmanship warranties.
- Generation baseline: a recent record of what the system produces, so you can confirm it performs the same after refit.
Check the warranty wording before you let a third party touch the array. Some installer workmanship warranties and insurance-backed guarantees are tied to the original installer handling the system. A removal by someone else can affect that cover even when the work is done well. If your original installer is available, that risk mostly disappears.
Does removal and refit affect your MCS certificate, FIT or SEG payments?
First, know which export scheme you are on, because the rules differ. Systems commissioned before April 2019 are usually on the Feed-in Tariff (FIT). Systems commissioned since then export under the Smart Export Guarantee (SEG). Both rest on the MCS certificate issued when the system was first commissioned, so the certificate and the original paperwork matter either way.
If you are on FIT, Ofgem’s rules recognise this exact situation. Temporarily removing an accredited installation, for example during roof repairs, does not in itself affect its compliance, and you may repair or replace generating equipment provided the installation stays the same technology, does not exceed its capacity, and is not decommissioned or relocated. The word that matters is decommissioned: if all the generating equipment is taken off and not put back, Ofgem treats the installation as decommissioned and FIT payments end. A genuine like-for-like lift and refit is fine. Permanent removal or a capacity change is not, so tell your FIT licensee if anything about the system changes.
If you are on SEG, eligibility requires that your installation and installer are MCS certified, or certified under an equivalent scheme, and your supplier may ask to see the certificate. A straight like-for-like refit keeps you inside that.
A like-for-like lift is not, by itself, a new installation that replaces the original MCS certificate, so keep the original certificate safe rather than assuming a refit reissues it. If the work changes the system, more panels, a different inverter, a higher capacity, that is an alteration, and MCS directs you to your original certified installer to amend the certificate. If that installer has stopped trading you are not stuck, because only the MCS Helpdesk can then reach your certificate, so contact MCS directly to arrange the amendment. An unrecorded change is what puts export payments at risk, not the act of lifting the panels.
Do you need to re-do G98 or G99 with your DNO?
Refitting the same system at the same rating does not change your existing connection agreement with the Distribution Network Operator, so a straightforward remove-and-refit does not need a fresh application. Your original G98 notification or G99 approval still describes the installation on the roof.
The connection agreement is about capacity, not about whether the panels were briefly on the ground. What triggers new DNO paperwork is a change in the exportable capacity: adding panels, a larger inverter, or crossing the boundary that pushes you from a G98 notification into a G99 application. Permanently decommissioning the system, or changing the inverter rating or export limit, is a different case again and does need DNO notification. If the refit is genuinely like-for-like, there is nothing new to tell the DNO. If it is an upgrade in disguise, handle the network application before the system goes live again.
The electrical reconnection itself is a different matter. Disconnecting and reconnecting the system is work that must meet BS 7671 and be tested, certified and recommissioned by a competent person. Treat the electrical certificate as a required output of the job, in the same way the original installation needed one. That certificate, not a verbal “it’s fine”, is what proves the array was put back safely.
Is removing and refitting your panels still 0% VAT?
Do not assume so. The 0% VAT rate that runs until 31 March 2027, in Great Britain since 2022 and Northern Ireland since 1 May 2023, is written for the installation of energy-saving materials, and HMRC’s guidance covers installing panels rather than repairs, maintenance or lifting an existing array during roof work. Whether a remove-and-refit of your own panels qualifies for the zero rate is not spelled out, so get the VAT treatment confirmed in writing on the quote rather than expecting it to be zero by default.
This matters most when solar work is bundled with roofing. Roof repair and re-roofing are normal building work, not energy-saving materials, so the roofing part of the invoice is standard-rated VAT regardless of what happens with the panels. If a contractor quotes the whole job at 0%, ask them to show which lines they are treating as zero-rated and why. After 31 March 2027 the installation relief steps back to 5%, so the timing of any planned work is worth checking against that date too.
None of this is tax advice for your specific job. It is a flag that the glib “solar is 0% VAT” line does not automatically apply to removal, refit or the roofing around it. Ask the contractor, and if the sums are large, confirm with HMRC.
The questions to ask before you book the work
Take these to every quote. They sort a coordinated job from a cheap price that turns into a leak and a warranty argument.
- Are access, panel handling and electrical recommissioning priced as separate lines?
- Who does the safe isolation, reconnection, testing and the electrical certificate, and are they competent to BS 7671?
- Who is responsible for weatherproofing each roof anchor when the panels go back on?
- Will you photograph and list the panel and inverter serial numbers before removal, and share that record?
- Does this refit keep the system like-for-like, or does it change capacity, and if so who handles the MCS amendment and DNO application?
- Does my workmanship warranty or insurance-backed guarantee survive this work, given who is doing it?
- Which parts of the invoice are you treating as 0% VAT, and which as standard-rated?
If a quote answers these cleanly and itemises the three cost buckets, you can compare it honestly against the next one. If it cannot, the low number is hiding work that will surface later. Start with the original installer, get the roof and array photographed before anyone climbs up, and keep the scaffold until the recommissioning certificate is in your hand.
