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.
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.
