Remapping

Van Remap & Insurance: What You Must Declare (and Why)

21 May 2026

Yes - a remap counts as a modification, so you need to tell your insurer. It's hardly the glamorous part of getting a tune, but skipping it can invalidate your policy, which means a claim getting waved away at the worst possible moment. The good news: declaring it is a two-minute job, often makes little or no difference to the premium on a mild economy or driveability tune, and we hand you a written note spelling out exactly what was done - so there's no he-said-she-said later.

Why you must declare it

A remap changes your ECU calibration - that's a modification, and insurers expect to be told about modifications. The risk is non-disclosure: if an undeclared mod comes to light at claim time, the insurer may reduce or refuse the payout, or void the policy entirely. For a working van that's a business-critical risk, and it's simply not worth taking to save a phone call.

Declaring a mild tune up front is almost always cheaper than a refused claim later. The premium difference (if any) on an economy or driveability tune is small; the cost of a voided policy after a write-off is not.


What to tell your insurer

  • That the ECU has been remapped (the engine calibration has changed).
  • The type - economy, driveability or fleet - and that emissions equipment is unchanged (no deletes).
  • The provider, and that you hold written documentation of the work.

Our insurance handover note spells all of this out - keep it with your policy documents so it's to hand if you ever need it.

Does it raise the premium?

It varies by insurer and by tune. A mild, emissions-intact economy or driveability tune is a modest change and often has limited premium impact; aggressive power tuning is viewed differently. Either way, declaring honestly is always cheaper than the alternative. And because our tunes keep your van road-legal (here's why that matters), there's nothing awkward to explain.

The rule

Always declare it. A two-minute call protects a policy worth tens of thousands - and our written note means you can prove exactly what was done.
