Solar Panel Removal and Refitting: What It Costs and How It Works

Most solar panels are designed to outlast one roof. A typical pitched roof lasts 40–60 years; solar panels are typically warrantied for 25 years and often generate well beyond that. If your roof was 20 or 30 years old when the panels went on, the maths quickly becomes obvious: at some point, the panels will need to come off so the roof can be replaced.

This is one of the most common things existing solar owners have to deal with, and the process is straightforward — but it does add cost and coordination to any roofing project.

When Would You Need This?

The most common reasons solar panels need to be removed and refitted:

Re-roofing — the single most common reason. If your roof covering (tiles, slates, or felt) needs replacing, the panels have to come off first. There is no way around this.

Chimney repair or removal — significant chimney work often requires scaffolding and access that conflicts with panels on that roof section.

Structural roof repairs — if roof timbers or rafters need attention, panels and their mounting rails must be removed to access the structure.

Leak investigation — where a suspected leak is under or near the panel array, removal may be needed to identify and fix the source. Note: leaks near solar panels are sometimes caused by poor original installation (inadequate sealing around fixing points) rather than the roof itself.

Moving house — panels are fixtures, so they typically stay with the property. Removing them before sale is unusual and generally not worthwhile, but it does happen.

The Process Step by Step

1. Electrical disconnection

Before a single panel is touched, the system must be safely isolated. This means disconnecting the DC cables (which run from the panels) and isolating the inverter from the AC supply. This must be done by a qualified electrician — ideally one with solar or PV experience.

DC cables from solar panels are live whenever there is daylight. Unlike your mains electricity, there is no switch that makes them dead — the current is generated continuously by the panels. Attempting to disconnect panels without proper training and equipment is extremely dangerous.

2. Scaffold erection

Unless scaffold is already going up for the roofing work (which it usually is), you will need safe working access to the roof. Most solar removal jobs are done within the scaffold already planned for the roofing project — confirm this with your roofer and solar installer so they are coordinating on timings.

3. Panel removal

Panels are unclipped or unbolted from their mounting rails and carefully lowered from the roof. Mounting rails and their fixings may also be removed depending on whether the roof needs full re-felting and batten replacement (which it usually does in a full re-roof). Junction boxes and DC cable runs are disconnected and capped.

4. Storage during works

Panels are typically stored on-site — either in your garage, shed, or garden — during the roofing work. They should be kept flat or at a shallow angle, not stacked without padding between them. If they cannot be stored on-site, your installer may offer off-site storage, which adds cost.

5. Refitting

Once the new roof is complete, the installer returns to refit the mounting rails (using new fixings into the new battens), reposition the panels, and reconnect all wiring. The system is then re-commissioned — tested and checked to confirm it is generating correctly.

6. Re-commissioning

After refitting, the system should be tested to confirm output is in line with expectations. Any monitoring system (such as an app-based portal) should also be checked. If your system is registered under the Smart Export Guarantee (SEG), you do not typically need to re-register after a like-for-like removal and refit, but it is worth checking with your energy supplier.

What It Costs

Costs vary by installer, location, and system size. These are typical figures for a standard UK domestic system as of early 2026:

For a typical 10-panel system (3–4 kW), expect the total removal and refit cost to fall in the range of £1,500–2,500, on top of whatever the roofing work itself costs. Larger systems or complex roof configurations will be at the higher end.

Insurance Considerations

If the removal is needed because of storm damage — tiles dislodged in a storm that have damaged the roof beneath the panels, for example — the cost of removing and refitting the panels as part of the repair may be covered by your buildings insurance policy.

Check your policy wording for "solar panels" and "accidental damage" or "storm damage" clauses. Some policies explicitly cover solar removal and refitting as part of a storm repair claim; others treat the panels separately. If in doubt, call your insurer before agreeing to any work — and get a written quote from your solar installer that separates the solar costs from the roofing costs, as the insurer will want this.

Finding an Installer for Removal and Refitting

Your first port of call should be the company that originally installed your panels, if they are still trading. They will have records of your system, know the mounting hardware used, and their work on removal and refitting falls within the scope of their original installation warranty.

If your original installer is no longer trading, or if you have moved into a property with existing solar, use the MCS installer search at mcscertified.com to find a local MCS-certified PV installer. Confirm they have experience with removal and refitting projects — most do, but it is worth asking.

Avoid using a general roofer to remove and refit panels. The electrical work requires a qualified electrician, and the remounting must be done correctly to maintain weatherproofing and avoid voiding panel warranties.
