If you’re wondering how much it actually costs to take your solar panels off your roof, whether to bring them with you when you move house, or what’s involved when the roofers need them out of the way for a re-tile, you’re in the right place. The cost depends on what you’re doing and why, and the answer in 2026 is that for one of these scenarios it’s a known, sensible expense, and for another it’s almost always a bad idea even though most articles will sell it to you as a great move.

Key points
For people who don’t have time to read the whole thing
- Removing and reinstalling on the same roof costs £1,000-£2,900 for a typical 4kW system, mostly driven by scaffolding and labour. Often unavoidable for re-roofing or major roof repairs.
- Full relocation to a different property costs £2,000-£5,000+ for the kit movements alone, before you account for the new property’s specifics, electrical work, or any roof modifications needed.
- If you’re on the original Feed-in Tariff scheme, moving the panels disqualifies you forever. Ofgem rules treat removed and reinstalled panels as second-hand, ineligible for FiT. For a 2011 install that can mean losing £25,000+ over the remaining contract.
- A new 4kW system in 2026 costs £5,500-£7,500 fully installed with a brand-new MCS certificate, full warranties and SEG eligibility. That’s often less than relocation once you count the FiT loss.
- Microcracks are the silent killer. Removing, transporting and refitting modules introduces stress that can knock 5-15% off long-term output, even when there’s no visible damage.
- For most house movers, the right move is to leave the panels behind. They add real value to the property, the FiT (if applicable) transfers to the new owner, and you start fresh at the new address.
01The two scenarios people mean by “relocate”
Before any cost makes sense, we need to separate two situations that sound similar but have very different answers. When someone asks about relocating panels, they almost always mean one of these.
Temporary removal at the same property
Re-roofing, repointing, loft conversion, or repairs that need the roof clear. Panels come down, work happens, panels go back up on the same fixings (or new ones if the roof structure changed).
£1,000-£2,900 All-in for typical 4kW systemFull relocation to a new property
You’re moving house and want to take the panels with you. Far more expensive and far less likely to make economic sense. Almost always loses you any FiT entitlement, and modern panels may outperform the ones you’re moving.
£2,000-£5,000+ Plus FiT loss, plus riskThe economics differ because Scenario A is essentially a known cost of being a homeowner, and the panels go back where they were designed to be. Scenario B introduces compounding hidden costs (FiT, warranty, fit issues, roof differences) on top of the headline labour bill. Most of the rest of this guide focuses on getting the maths right for whichever situation you’re in.
- Decommissioning
- The formal process of safely electrically isolating and removing a solar PV system, including the paperwork sent to your DNO and FiT supplier.
- DNO / G98
- Distribution Network Operator. They were notified of your original install under the G98 (or G99) regulations. A relocation requires a fresh notification at the new address.
- Recommissioning
- The technical sign-off after reinstallation: testing isolation, polarity, earth bonding, and registering the system as live. Required for SEG eligibility.
- Microcracks
- Hairline fractures in the silicon cells that develop from physical stress. Often invisible but cumulatively reduce output. Removal-transport-refit is a high-stress sequence.
- WEEE
- Waste Electrical and Electronic Equipment regulations. Solar panels disposed of (rather than reused) must be recycled through approved channels. Affects costs if you’re not relocating but disposing.
02The real cost breakdown for 2026
The all-in figure depends on which scenario you’re in, panel count, roof access, and whether you’re mid-refurbishment with scaffolding already up. Here’s how the numbers stack at the line-item level for a typical 4kW system (10-12 panels).
| Stage | What it covers | Approx. cost |
|---|---|---|
| Electrical disconnection | Qualified electrician isolates DC and AC sides, certifies decommissioning | £100-£200 |
| Scaffolding | Required for any roof work above single-storey height. Hire period typically 1-2 weeks | £200-£600 |
| Panel removal | Crew on roof unclipping panels, safely lowering each (each weighs 18-22kg) | £200-£600 |
| Mounting system removal | Brackets, rails, roof penetrations sealed and tiles re-bedded | £100-£300 |
| Roof tile replacement/repair | Brokens or cracked tiles around old fixings. Variable. | £100-£300 |
| Subtotal: removal only | £500-£1,500 | |
| Storage during works | Often free for short turnarounds, more for longer projects | £0-£200 |
| Reinstallation labour | Refit panels onto same or new mounting, recable, terminate | £400-£1,000 |
| Recommissioning & certification | System tests, MCS certificate update, DNO renotification | £100-£200 |
| Total: remove + reinstall (Scenario A) | £1,000-£2,900 | |
| Transport to new property | Van hire, careful packing, insurance during transit | £150-£400 |
| New roof survey | Structural assessment of new roof, layout design | £150-£350 |
| New mounting system | Old rails rarely fit a different roof properly. Fresh kit usually needed | £300-£600 |
| Fresh DNO notification & SEG registration | G98 paperwork, fresh smart meter export setup | £0 (but time) |
| Total: relocation to a new property (Scenario B) | £2,000-£5,000+ | |
Two things to flag from these numbers. First, the numbers compound; if your roof is steep, on a tall house, or you have a battery to move alongside the panels, expect to be at the upper end of every range simultaneously. Second, the cost of buying a brand-new 4kW system for £5,500-£7,500 starts to look genuinely competitive, especially since you also get fresh manufacturer warranties and full MCS sign-off. Our breakdown of how much solar panels actually cost covers the new-install side in detail.
03The hidden costs that destroy the maths
The line items above are the ones a quote will show you. The hidden costs are where most people end up regretting a relocation, and they’re rarely flagged upfront by the company doing the work. Three matter most.
Hidden cost 1: lost Feed-in Tariff payments
If your system was installed before April 2019 and you’re on the FiT scheme, this is almost certainly the most expensive item on the list. Ofgem’s rules are unambiguous: removed and reinstalled panels are treated as second-hand and lose all FiT eligibility, permanently. The FiT scheme closed to new applicants in 2019, so there’s no way to re-register the relocated system, even if the panels are physically the same.
This is the biggest single number most homeowners miss
A 4kWp system commissioned in 2011 receives roughly £1,500-£1,800 a year in FiT payments at current 2025/26 rates. With around 16 years left on the original 25-year contract, that’s £24,000-£28,000 of guaranteed, index-linked income, gone the moment the panels come off the roof. No relocation cost calculation works without this number on the page.
The exception is for genuinely large, commercial-scale systems above 50kWp, which can be relocated and retain FiT under specific 2019 modifications. For residential rooftop systems (4-10kWp typical), there is no exception. The official position is set out in Ofgem’s FiT generator guidance.
If you sell the property instead, the FiT transfers to the new owner with a Change of Ownership Form and your new buyer inherits the income stream. The panels effectively become a saleable, income-producing asset attached to the property, which is one good reason buyers typically value solar-equipped homes higher (more on that in our piece on how solar panels affect home value).
Hidden cost 2: warranty void or refusal
Most panel manufacturer warranties are written around a single original installation by a certified installer. Removing the panels and reinstalling them elsewhere typically voids the product performance warranty, and almost always voids the workmanship warranty (which was tied to the original installer’s MCS certificate). Some manufacturers explicitly exclude “relocated” systems in their small print.
The practical impact is that if a panel fails three years after relocation, you have no warranty to claim against. You’re a private buyer of second-hand kit, with private-buyer rights only. Our guide to solar panel warranty claims covers what those warranties typically include, and what relocation removes.
Hidden cost 3: microcracks and performance loss
This is the technical one. Solar panels are surprisingly fragile under bending stress, and the sequence of unclipping, lowering on a rope or hoist, transporting in a van, then refitting to (often) different mounting kit introduces multiple high-risk handling moments. Most of the resulting damage is invisible: hairline cracks in the silicon cells that don’t show on the surface but accumulate to reduce output over time.
You won’t see this on a generation graph the day after the install. You’ll see it five years later, as your annual total drifts noticeably below what an equivalent unrelocated system in the same area is producing. For a deeper look at the underlying physics, our explainer on solar panel microcracks goes into the IEC test standards and what genuine damage looks like.
04When relocation actually makes sense
Despite the warnings, there are scenarios where the numbers genuinely work. Here’s when relocation is a sensible move rather than a sentimental one.
Worth doing
- Re-roofing or major roof works at your current property (Scenario A always)
- System is post-2019 (no FiT to lose) and less than 5 years old
- You’re moving locally and the same installer can handle both ends
- You have a battery or premium kit (Tesla Powerwall, Enphase microinverters) worth £3,000+ in current market value
- The new property has equally good or better orientation and pitch
- You’re moving from a property you’ve not been in long, where panels haven’t yet paid back
Not worth doing
- You’re on FiT and the loss exceeds the new-install cost (almost always for pre-2014 systems)
- Panels are 8+ years old. The economics tilt heavily towards new modern panels
- The new property has worse orientation, pitch, or significantly more shading
- The original installer is no longer trading (very common with older systems)
- You’re moving cross-country and would need a different installer at each end
- You’re hoping panels alone justify the move (the value is in the panels-with-house combo)
The “8+ years old” point is worth pulling apart. A 2017-vintage 4kWp system was probably 250W-275W per panel. A 2026 panel is typically 400W-440W. For roughly the same labour and roof space, a new install delivers 50-70% more energy. Add in the better warranties, microinverter or optimiser options, and the SEG eligibility, and the case for keeping old panels gets steadily weaker.
05Better alternatives if the maths doesn’t work
If the costs above have left you wondering whether to bother, you’re in good company. Here are the alternatives that most solar industry professionals will quietly suggest when no one’s selling.
| Alternative | Best for | Approx. value |
|---|---|---|
| Sell with the house | Most house movers, especially with FiT | +£3,000-£8,000 to property value typically |
| Install fresh at the new property | Anyone moving who wants solar both before and after the move | £5,500-£7,500 for new 4kW system, with full warranty and SEG |
| Sell second-hand to a self-installer | Off-grid hobbyists, narrowboaters, garden builds | £40-£80 per panel typical, often less than relocation cost |
| Donate to community project | Older systems with FiT lost anyway | Tax-deductible if a registered charity |
| Recycle through WEEE-approved route | Damaged or end-of-life panels | Free at most participating sites |
“Sell with the house” deserves a mention in its own right because it’s both the easiest option and almost always the most financially sensible. Solar panels are classified as fixtures in property law, included by default in a sale unless explicitly excluded. The new owners pick up your FiT contract via a Change of Ownership Form and continue the income stream. You walk away from the install completely. If you’re going down this road, our guide on buying a house with solar panels is also worth sharing with your buyer so they know what they’re getting.
For homeowners with second-hand panels they want to dispose of rather than relocate, the secondary market is real but priced low. Used 250W-350W panels typically sell for £40-£80 on online marketplaces, depending on age, brand and condition. Buyers tend to be off-grid enthusiasts and self-builders rather than people putting panels on residential roofs. Our piece on used solar panels covers the second-hand market more fully.
06The right order to do things if you’re proceeding
If you’ve worked the numbers and relocation is the right call, the order in which you tackle each step matters. Skipping ahead causes regret. Here’s the sequence reputable installers will follow.
The relocation sequence
Two practical tips that aren’t on the diagram. First, photograph every panel’s serial number before removal and check them again after reinstall. It sounds paranoid but a few cases each year involve panels going “missing” between sites. Second, get an output baseline before removal (your inverter will have last month’s totals) so you can compare against the first three months at the new property and catch any major performance drop early.
Single installer, both ends
The best price-and-quality outcome almost always comes from using one installer for both the removal and the reinstallation, ideally the same crew. They have skin in the game on the panels arriving in good condition, they handle the paperwork end-to-end, and they typically discount the combined job versus two separate firms. Always insist on MCS certification at both ends. The MCS register is searchable by postcode.
Most house movers should leave the panels behind
If you’re moving house and considering taking your panels with you, the advice from most of the industry is: don’t. The relocation costs alone (£2,000-£5,000+) often approach or exceed what a brand-new 4kW system costs in 2026. Add in lost FiT payments for older systems, voided warranties, and microcrack risk, and the case becomes very hard to justify. Selling the property with the panels in place transfers the income stream to the new owner and reflects in the sale price.
If you’re doing roof work and need the panels off temporarily, this is just a known cost of being a homeowner. Budget £1,000-£2,900 for a typical system, use the same MCS-certified installer for both ends of the job, and don’t try to split it across multiple firms. Get the panels back on the same fixings if you can, and check the first three months of generation against your pre-removal baseline.
If you’re going ahead with a full relocation despite the maths, do it with eyes open: confirm the FiT loss in writing before any panel comes off the roof, photograph every serial number, and use one installer for both ends. The economics rarely work, but where they do, doing the steps in the right order is the difference between a smooth project and an expensive lesson.
