01
Does a remap affect insurance?
It can. An ECU remap changes the vehicle's engine-management software from its standard calibration. Insurers may consider that a modification, including when the change is software-only and there are no visible parts fitted.
Whether it affects your policy or premium depends on the insurer, the vehicle, the remap and your policy terms. An insurer may accept the change, adjust the premium or terms, or decide it cannot offer cover. Another insurer may assess the same vehicle differently.
The important point is not to guess what your insurer will decide. Tell them about the remap and get their response before the work is carried out wherever possible.
02
Why insurers ask about an ECU remap
An ECU manages how an engine operates. A professional calibration can alter how the vehicle responds to throttle input and delivers power and torque. Insurers may want to know about changes that affect a vehicle's specification or performance so they can assess the risk under their own rules.
Some insurers specifically ask about engine tuning or electronic modifications. Others may use broader wording about changes from the manufacturer's standard specification. Read the question carefully and answer it fully. If you are unsure whether a particular question includes an ECU remap, ask the insurer or broker directly.
A remap does not become irrelevant because it is less visible than a hardware change. If your policy asks about modifications, do not assume a software change can be left out.
03
What can happen if you do not disclose a remap?
Problem: The remap is not declared, or the insurer is given incomplete information.
Consequence: If the insurer later finds out, it may affect your cover or a claim. Depending on the circumstances, the questions asked, and the policy terms, the insurer could cancel or void the policy, change its terms, or refuse or reduce a claim.
Solution: Tell the insurer about the modification accurately and keep a record of its response. If you have already had a remap, contact your insurer promptly rather than waiting for renewal.
The outcome is determined by the insurer and the specific policy; it cannot be guaranteed in advance. If the insurer will not cover the vehicle, discuss suitable alternatives with a broker or a provider of modified-vehicle insurance. Do not rely on the assumption that an undeclared remap will not matter.
04
What to tell your insurer before tuning
Give the insurer enough information to identify the change and assess it. Explain that you are considering an ECU or engine remap and describe the intended calibration as accurately as you can. If the insurer asks for details such as the vehicle's revised output or the type of remap, provide the information available and ask Kent Eco Tuning for clarification if needed.
Ask the insurer to confirm:
- Whether it will cover the vehicle with the proposed remap. - Whether the premium, excess or policy terms will change. - Whether it requires written evidence or any further details. - Whether the change needs to be recorded on your policy documents.
Where possible, contact the insurer before booking the work. Ask for confirmation in writing, such as an email or an updated schedule, and keep it with your policy documents. A phone conversation can be a useful first step, but written confirmation gives you a clear record of what was discussed.
If the vehicle has already been remapped, or you bought it with a remap already installed, tell the insurer even if you did not arrange the work yourself. Explain what you know and ask what information it needs. If you do not know the calibration details, say so rather than guessing.
05
Will a remap increase your insurance premium?
Not necessarily. A premium may increase, stay the same or be affected in another way. Some insurers may decline to cover a modified vehicle, while others may be willing to insure it on different terms.
There is no single premium outcome that applies to every driver. Insurers assess vehicles and modifications according to their own underwriting criteria, so a quote from one provider does not predict what another will decide.
Do not choose a remap on the assumption that insurance will remain unchanged. Contact your insurer first, describe the proposed work and compare options if necessary. That is more reliable than finding out after the remap has been completed.
06
Does insurance disclosure affect cars, vans and business vehicles?
The same careful approach applies to cars and vans. If a working van is remapped, tell the insurer that provides its cover. Tradespeople and fleet operators should also check who is responsible for reporting modifications and make sure the information is passed to the relevant insurer or broker.
For business vehicles, explain how the vehicle is used as well as what work is planned. The insurer may need to assess the vehicle in the context of its policy and use. Do not assume a private-car policy and a business-vehicle policy treat modifications in the same way.

Remap & Insurance FAQs
09
Do I have to tell my insurer about a remap?
You should tell your insurer and answer its questions about modifications truthfully. Ask it directly if the policy wording is unclear, and keep a record of its response.
10
Should I tell my insurer before or after the remap?
Contact the insurer before the work wherever possible. If the vehicle is already remapped, or you discover a remap after buying it, contact the insurer promptly and ask what it needs to update your cover.
11
Can a remap void my insurance?
A remap does not automatically void every policy. However, failing to disclose a modification when required could lead to serious consequences, potentially including cancellation or invalidation of cover, or an impact on a claim. The outcome depends on the circumstances and the policy.
12
Will every insurer charge more for a remap?
No. The insurer may increase the premium, leave it unchanged, change other terms or decline cover. Only the insurer can confirm how it will treat your vehicle.
13
Can Kent Eco Tuning tell me what my insurer will charge?
No. Kent Eco Tuning can explain the work planned and provide relevant vehicle or calibration details, but it cannot set your premium or confirm your policy cover. Those decisions belong to your insurer or broker.
