Specialist Insurance UK 2026 — Phone, Gadget, Motorbike, Wedding and MoreInsurance Excess Explained — Compulsory vs Voluntary and How to Save
What is insurance excess, what's the difference between compulsory and voluntary excess, and how to choose the right level to save money on premiums.
Every insurance policy has an excess — the amount you pay before your insurer covers the rest. Understanding how excess works helps you make smarter decisions about your cover and potentially save hundreds on premiums.
How Excess Works
| Element | Detail |
|---|
| Compulsory excess | Set by the insurer — you can’t change it |
| Voluntary excess | Extra amount you choose to pay on top |
| Total excess | Compulsory + voluntary combined |
| When you pay | At the point of making a claim |
Example
| Scenario | Amount |
|---|
| Claim amount | £2,000 |
| Compulsory excess | £150 |
| Voluntary excess | £250 |
| Total excess you pay | £400 |
| Insurer pays | £1,600 |
Excess by Insurance Type
| Insurance type | Typical compulsory excess | Common voluntary excess options |
|---|
| Car insurance | £100 – £350 | £0 – £1,000 |
| Home insurance (buildings) | £100 – £250 | £0 – £500 |
| Home insurance (contents) | £50 – £150 | £0 – £500 |
| Travel insurance | £50 – £100 | £0 – £250 |
| Pet insurance | £50 – £150 | £0 – £250 |
| Private medical insurance | £0 – £500 | £0 – £5,000 |
Why Insurers Set Higher Compulsory Excess
| Reason | Example |
|---|
| Young drivers | Car insurance compulsory excess of £300–£500 for under-25s |
| Flood-risk areas | Buildings insurance excess of £500–£2,500 for flood claims |
| Certain breeds | Pet insurance excess increases with unusual/risky breeds |
| Subsidence | Buildings policies often have £1,000 subsidence excess |
| Pre-existing conditions | Health insurance may set higher excess for specific conditions |
How Voluntary Excess Affects Your Premium
Car insurance example:
| Voluntary excess | Typical annual premium | Saving vs £0 excess |
|---|
| £0 | £600 | — |
| £100 | £560 | £40 |
| £250 | £510 | £90 |
| £500 | £470 | £130 |
| £1,000 | £440 | £160 |
The savings diminish at higher levels — going from £0 to £250 saves more per pound of excess than going from £500 to £1,000.
Home insurance example:
| Voluntary excess | Typical annual premium | Saving vs £0 excess |
|---|
| £0 | £250 | — |
| £100 | £230 | £20 |
| £250 | £210 | £40 |
| £500 | £190 | £60 |
Choosing the Right Excess Level
The Decision Framework
| Question | If yes… | If no… |
|---|
| Could you afford to pay £500 unexpected? | Consider £250–£500 voluntary excess | Keep excess low (£0–£100) |
| Do you claim rarely (once every 5+ years)? | Higher excess makes sense | Lower excess is safer |
| Is the premium saving significant? | Worth increasing | Not worth the risk |
| Can you keep an emergency fund for excess? | Higher excess + emergency fund works | Keep excess affordable |
Golden Rules
| Rule | Why |
|---|
| Never set excess higher than you can afford | You’ll pay it when you’re already in a difficult situation |
| Calculate the break-even point | If raising excess saves £100/year but adds £250 to your excess, it takes 2.5 claim-free years to benefit |
| Consider your claim history | If you claim frequently, low excess is better |
| Keep emergency savings | Having the excess amount in easy-access savings gives peace of mind |
Excess Protection Insurance
| Feature | Detail |
|---|
| What it is | A separate policy that refunds your excess if you claim |
| Cost | Typically £20 – £60/year |
| Covers | Car insurance excess, sometimes home and travel too |
| Limits | Often limited to 1–2 claims per year |
| Worth it? | Only if excess is high AND you’re likely to claim |
Is It Worth It?
| Scenario | Worth it? |
|---|
| High excess (£500+) and accident-prone area | Possibly |
| Low excess (£100–£250) | Probably not — the protection costs nearly as much as the excess |
| Young driver with £500 compulsory excess | Can be worthwhile |
| Careful driver with no claims | Usually no |
Common Excess Mistakes
| Mistake | Why it’s a problem |
|---|
| Setting excess too high to save on premium | Can’t afford to claim when you need to |
| Forgetting about compulsory excess | Your total is compulsory + voluntary |
| Not knowing your excess amount | Check your policy documents now |
| Making small claims near the excess value | Claim of £300 with £250 excess — you get £50 but may lose no-claims discount |
| Not claiming when you should | A £5,000 claim with £500 excess is absolutely worth claiming |
When NOT to Claim
| Situation | Excess | Claim value | Insurer pays | Worth claiming? |
|---|
| Minor damage | £250 | £300 | £50 | No — lose no-claims |
| Medium damage | £250 | £800 | £550 | Maybe — weigh NCD loss |
| Major damage | £250 | £5,000 | £4,750 | Yes |
| Total loss / theft | £250 | £15,000 | £14,750 | Yes |
Summary
| Key point | Detail |
|---|
| Compulsory excess | Set by insurer — can’t change |
| Voluntary excess | You choose — higher = lower premium |
| Total excess | Compulsory + voluntary |
| Best approach | Set as high as you can comfortably afford |
| Emergency fund | Keep your excess amount in easy-access savings |
| Excess protection | Rarely worth it unless excess is very high |
| Don’t claim for small amounts | Protect your no-claims discount |
