Subframes make up a significant amount of a car's structural integrity, being the thing that ties the suspension to the body shell. However, like any underbody component, they are subject to extremely harsh conditions, especially in the UK, with our damp, salted roads.

This article explores the costs involved with repairing a corroded subframe and what to look out for when having the work done. 

Almost all modern cars have both a front and rear subframe; these provide stiffness and strength for the suspension components to mount to the bodyshell. The front subframe typically also supports the engine, gearbox and drivetrain components. 

Car subframes are almost always made from steel, which is a strong and cheap material to use. It does, however, rust readily if not sufficiently protected.

The cost to repair a corroded subframe can range from £300 to £3,000, depending on how bad the corrosion is, and how complex the car is.

Minimal rust can often be wire-brushed and treated, which could cost as little as £300 and be done in an afternoon, but if your subframe is very rusty and needs replacing, expect to pay a much larger bill.

Factors that affect subframe repair cost include:

Cars are mainly made of steel, a metal very susceptible to corrosion in the right circumstances. Water causes the iron in the metal to turn into iron oxide, AKA rust. Thanks to our decidedly wet weather in the UK, cars here are more susceptible to rust than most. 

Another contributing factor is salt, which accelerates the corrosion process, and with tons of it being spread on UK roads every winter, poorly protected cars don't stand a chance!

If you cannot avoid driving on UK roads throughout the winter, there are some things you can do to protect your car's subframe and entire underbody from rust:

The best way to protect your car from corrosion is to avoid driving in the winter, but this is obviously not feasible for most people, the next best option is to apply a protective coating to the subframes, suspension components and underbody. 

Products such as Lanoguard and underbody sealant can help protect the metal, but be sure to apply them only when the metal is free from rust; otherwise, any existing rust will continue to spread under the coating. 

Mud and salt can also stick to the underside of your car, especially if the roads are particularly dirty. Pressure washing the suspension, wheel arches and underbody may be a bit extreme for most, but it can help to prevent corrosion in the long term.

How to check if a car's subframe is rusty

Take a look under the car at both the front and rear. The subframe should be easy to spot; look for where the suspension arms are attached to, it will be a different colour to the bodyshell.

If you’re looking at a car for sale, or simply want to check your own car, it can pay to see if the subframe is rusty, look for obvious signs of rust, large amounts of orange, or powdery rust is cause for concern.

With how expensive certain brands and types of tyres are nowadays, being able to repair a puncture can be a great money saver, should a nail or some other piece of debris find its way into the tread. 

But how much does tyre puncture repair cost, and when can it be done? 

In the UK, tyre repair typically costs between £30 and £40 per tyre.

Naturally, this figure varies by location, type of tyre to be repaired and the type of shop you go to. National chains often have online deals or coupon codes you can make use of, but local independent repair shops may be more flexible with bookings.

Most garages will follow the same rules on when a tyre can or cannot be repaired, these are generally dictated by the British standard BSAU 159 - which can be found online. 

Whilst the standard above is quoted by most garages as the defining guide on what can and cannot be repaired, each company is likely to have its own policy on this.

This company-specific policy is likely to be more cautious than the British standard, for liability reasons, so in some cases a garage will decline to repair a tyre, instead advising you to buy a new one.

No, run-flat tyres cannot be repaired, even if the damage is in the main portion of tread, and is smaller than the max permissible size. 

Run flat tyres are designed to allow the car to be driven a short distance - typically around 50 miles - after a puncture. However, this causes irreparable damage to the tyre’s sidewall, so the tyre should no longer be used.

Getting a puncture is annoying at best, and can sometimes be very expensive if the tyre can't be fixed. Here are some tips to avoid damaging your tyres:

Your car's exhaust not only reduces the sound of the engine, but also carries harmful fumes to the back of the vehicle instead of allowing them to enter the cabin. If your exhaust is damaged, you should get it fixed as soon as possible. 

But how much does an exhaust silencer cost to fix? This article will explain all. 

How much does it cost to repair an exhaust silencer?

Exhaust repair costs range from £30 for a simple repair to over £600 for a replacement part, depending on the car and type of garage.

Sometimes a patch or clamp is all that's needed, in which case a mechanic could have you back on the road in under an hour, with a bill of around £30 - £50.

In some cases, a new part is required, such as a back-box or centre silencer; these can range from £220 to over £500, including fitting.

There are a number of issues that could crop up at an MOT, particularly if the exhaust is leaking gases:

The term “exhaust” generally refers to a number of different parts that attach to one another. Whilst not all cars will have all of these parts, the following list includes most of the parts you need to know about:

When your car suddenly starts squeaking, rattling, or making any other unusual engine noises, it’s usually a sign that something’s off. The good news is that strange car noises are often early warning signs, which means a timely intervention could save you from expensive repairs.

Let’s walk through nine common car noises, what might be causing them, and what to do next.

1. Why is my car making a noise when I turn?

If you hear clicking, knocking, or a grinding noise while turning your car, it’s often linked to issues with your CV joint, power steering system, or suspension components.

What should I do about a noise when turning?

If you hear clicking, knocking, or whining when turning, avoid driving long distances until it’s inspected. Check your power steering fluid level if you can, as low fluid can cause whining sounds. Clicking or clunking often points to worn CV joints or suspension parts, so have a mechanic look at it promptly to avoid further damage.

How much does suspension repair cost in the UK?

2. Why is my car making a rattling noise?

If your car is making a rattling sound while driving (or even idling), it usually means something under the bonnet or near the exhaust system is loose or worn out.

What should I do about a rattling noise in my car?

Check under the car when it’s cool for any visibly loose heat shields or exhaust parts. If the rattle gets louder while idling or driving, book a mechanic appointment soon. Rattles can be harmless, but they can also point to failing exhaust mounts or catalytic converter issues that need attention.

How much does it cost to replace an exhaust?

Ticking noises are usually an early sign of issues with your engine’s lubrication system of valve components. You might notice the ticking more when the engine is cold, or after the car’s been sitting for a while. While some ticking noises can be harmless, others can lead to performance issues or even severe damage if left unresolved. So, what causes ticking sounds in a car?

What should I do about a ticking noise in my car?

Start by checking your engine oil level and condition. If the oil is low or dirty, top it up or change it to see if that helps. If it continues, don’t ignore it – have a professional mechanic check it out. 

50% of UK drivers delay repairs due to cost

, and many end up paying the price with bigger, more expensive problems down the line. 

4. Why is my car making a squeaking noise?

If your car makes a squeaking sound when braking, accelerating, or starting up, it’s usually down to something worn, loose, or under stress.

What should I do about a squeaking noise in my car?

Start by checking the likely causes: brake pads, the serpentine belt, and the clutch if you drive a manual. If the brake pads look thin or worn, replace them as soon as possible. 

If the squeak happens on cold starts or when you accelerate, have the serpentine belt inspected for wear or tension. And if you hear it while changing gears, get the clutch checked. A quick visit to a mechanic can confirm the issue and prevent bigger problems later.

5. Why is my car making a whistling noise?

A whistling noise while driving usually means air is escaping from part of your engine, often through a cracked hose, vacuum leak, or damaged seal. The sound can be high-pitched and may get louder when accelerating or idling. This is one of those noises that’s easy to overlook, but it could be masking a much bigger problem with your engine’s air-fuel mixture.

What should I do about a whistling noise in my car?

Check for any obvious leaks in vacuum hoses or the intake system and listen carefully when the engine is idling. If you suspect a loose or damaged hose, avoid driving long distances until a mechanic inspects it, as air leaks can affect performance and fuel economy.

If one of these car noises turns into a real issue, don’t panic about the bill. With Bumper’s interest-free 

, you can avoid a lump-sum payment and handle the cost like a pro. It’s a smarter alternative to a traditional car repair loan, with no interest and no stress. 

6. Why is my car making a knocking noise from the engine?

If you hear a knocking or thudding noise from your engine, especially when accelerating, there might be some abnormal combustion or worn internal components.

What should I do about a knocking noise from the engine?

Stop driving if the knocking is loud or persistent, as it could signal serious engine damage. Check your car’s oil level and fuel quality, then book a professional inspection as soon as possible. Engine knocks can quickly worsen if left untreated. 

7. Why is my car making a scraping noise when driving or braking?

A scraping or grinding sound (especially when slowing down or turning) usually means some friction between parts of your car. It’s a noise you should never ignore, as it’s often linked to your car’s braking systems or wheels. You might notice the noise gets worse when you press the brake pedal or drive at low speeds. 

Avoid driving until you find the cause. Check for debris around the wheels and look for signs of worn brake pads. If the noise persists or braking feels weaker, get your car to a mechanic immediately, as braking issues can be dangerous.

8. Why does my car backfire when accelerating?

during acceleration, this could be a backfire caused by fuel igniting outside the combustion chamber. While it sounds dramatic, it’s often down to a simple issue that can be easily corrected.

What should I do if my car backfires when accelerating?

Check your fuel quality and make sure your car isn’t overdue for a service. Backfiring often points to ignition or fuel system issues, so arrange a professional inspection quickly to prevent damage to your exhaust or engine.

9. Why does my car vibrate while driving?

If your car feels like it’s vibrating or buzzing at higher speeds, it’s usually a sign that something’s misaligned in the wheels, drivetrain, or suspension. These vibration noises often start small and build gradually over time. You might notice them in the steering wheel, through your seat, or even under your feet. 

What should I do if my car vibrates while driving?

Slow down and pull over if the vibration feels severe or the car is hard to control. Check your tyres for visible damage or low pressure, then book a wheel alignment or mechanical check to diagnose any worn suspension or drivetrain parts.

 option, you can split the cost of your fix into interest-free monthly payments, without the pressure of a lump-sum bill. Apply online in seconds, or directly through one of 5,000+ trusted garages and dealerships across the UK. Start now!

Some car noises are perfectly normal and nothing to worry about. These include the hum of tyres on the road, a soft whoosh from the air vents, the gentle sound of the engine idling, and the clicking of indicators. Occasional brake squeaks in wet weather or a faint fan belt sound during a cold start can also be normal. However, if noises become louder, persistent, or unusual, it may be a sign of a developing problem that needs attention.

A healthy engine should run smoothly with a consistent, steady hum. It’s normal to hear a quiet ticking as fuel injectors work, a low growl when accelerating, or a gentle whirring from belts and pulleys. These sounds indicate that components are operating as they should. Loud knocking, rattling, grinding, or high-pitched squealing, however, are not normal engine noises and are usually caused by an issue that needs a mechanic’s inspection.

9 car noises to look out for (and what to do)

Whether it’s a tiny chip from a passing lorry or a long crack creeping across your screen, you’ve probably got one question on your mind when it comes to repairing a windscreen: 

The good news is, repairing a chipped windscreen is usually fast, simple, and far cheaper than a full replacement. Here’s your handy guide to windscreen chip repair costs, what affects the price, and how to make your next visit to the garage a little more bearable with Bumper. 

How much does it cost to repair a chipped windscreen?

In the UK, repairing a chipped windscreen typically costs £40–£70. The exact amount depends on the size and position of the chip, the type of vehicle, and your garage’s rates.

Smaller chips, especially ones that haven’t spread, can often be fixed quickly and affordably. But leave it too long, and that small chip could develop into a full crack, leading to a 

How do professionals repair windshield chips? 

Most professional windscreen chip repairs take less than 30 minutes if the chip is small, shallow, and hasn’t started to spread. 

How much does a cracked windscreen repair cost?

If your chip has turned into a crack, the cost increases quite a bit. Replacing a cracked windscreen in the UK can cost between 

Why is a cracked windscreen more expensive?

Replacing a cracked windscreen costs more than a simple chip repair because modern car windscreens are far more advanced than they used to be – often integrated with high-tech features that require specialist parts and extra labour, including: 

These need to be carefully removed, replaced, and recalibrated when the windscreen is changed. The result? More time in the workshop, higher part costs, and sometimes even specialist tools or software to reset the tech. Expect replacement costs for these kinds of windscreens to reach anywhere up to £1,000.

Windscreen repairs are becoming more frequent and more expensive. 

According to insights from insurance firm Allianz

, the average windscreen claim in 2024 reached £327, up from £308 in 2022 – a £19 increase in just two years!

And it’s not just individual claim costs going up; the volume of claims is increasing too. More drivers are reporting windscreen issues and needing repairs, particularly for small chips, which rose 4% in 2023 compared to the previous year. Full windscreen replacements saw an even sharper increase, up 13% year-on-year.

One of the key drivers? These modern, new-fangled windscreens! 

Claims for heated windscreens alone increased by 21% between 2021 and 2023. The rise of Advanced Driver Assistance Systems (ADAS)-equipped vehicles is also pushing costs higher. In 2016, just 1% of windscreen claims involved ADAS recalibration. In 2023, that number jumped to 44% (that’s nearly half!). As these systems become more common, repairs require precise recalibration of sensors and cameras to make sure the road safety features work properly.

Can you repair a stone chip in a heated windscreen?

Yes, you can repair a stone chip in a heated windscreen, but it might be slightly trickier. Heated windscreens contain ultra-thin heating wires embedded between layers of glass. These wires are designed to defrost your windscreen quickly in cold weather. If a chip or crack forms near or over these elements, it can be trickier to repair without damaging the heating system. That being said, a repair is usually possible if the chip is small, hasn’t spread, and if the heating elements aren’t visibly damaged. 

Your garage may recommend replacing a heated windscreen if: 

Ford’s original heated windscreen tech – dubbed “Quickclear” in the UK – first appeared in the 1980s Granada Scorpio, using a barely visible mesh of wires to clear frost in under three minutes. It’s now a staple feature on many mainstream models, though replacing one can still cost significantly more than a standard screen.

Windscreen chips are typically caused by sudden impacts from small, hard objects that have enough force to displace the glass they hit. Here’s a more detailed breakdown: 

Harsh UK weather (e.g. hail, heavy rain, and grit spread during winter) can lead to sudden impact or gradual wear on your windscreen. Winter driving increases the risk of a chip, especially on rural or poorly maintained roads. 

One of the most common causes of windscreen chips is loose stones or grit kicked up by other vehicles’ tyres, especially lorries and vans. These stones hit windscreens at high speeds and cause immediate impact damage to the glass.

Over time, windscreen glass becomes more vulnerable to damage. Older windscreens may have developed tiny surface cracks or weakened areas due to natural wear, making them far more likely to chip when hit with even small debris.

Faulty or worn suspension components can indirectly damage your windscreen due to increased vibrations or harsh jolts when driving over potholes or speed bumps. Over time, these can weaken the windscreen structure or turn a small chip into a larger crack.

How soon should I repair my windshield chip?

You should repair a windscreen chip as soon as you spot it. Chips can spread fast, especially with temperature changes or when driving over potholes. Not sure whether the chip needs repairing or replacing entirely? Here are some signs it might be too late for a repair:

What happens if you delay a windscreen chip repair?

If you leave your windshield repair too late, you risk the damage getting worse and making it much harder to legally drive on the road:

Listers Audi Birmingham has been named the latest site to win Bumper’s Dealership of the Month following a training session, encouraging the team to be proactive in offering Bumper and maximise every opportunity. 

The Midlands site has used PayLater to empower customers to make essential repairs to their vehicles since 2018. 

To build the confidence of service advisors across the division, Listers Audi arranged an internal training session with Group Trainer, Chris Kitson. 

Focusing on how to talk about the interest-free monthly payment option with customers, the training day empowered advisors with new tools to better engage customers. 

Ed Sanders, Aftersales Manager, shared some encouraging results. 

“We've seen a noticeable uplift in recovery rates, red work sold, and parts sold per throughput – a real positive for us as a dealer,” said Sanders. 

“The training has given the relatively new team a fresh perspective, and it's been great to see their growing confidence when it comes to presenting and selling.” 

With over a 100% increase in PayLaters this month, Listers Audi Birmingham has been able to make a real impact to their local community, keeping their customers’ vehicles safe on the road. 

Tom Cox, Listers Brand Director, said, “Great results so soon after the training, well done to Ed and the whole team at Audi Birmingham for your engagement and commitment.” 

Steve Tapp, Service Manager, said, “In May, we took a proactive step to enhance the way we present Bumper’s monthly payment options to our customers. Recognising the importance of clear, transparent finance solutions, we retrained all of our staff across both Audi and Skoda.

“Previously, Bumper was often introduced only as a backup solution during objection handling. Following the training, we have now embedded Bumper into the core of our service process. The bookings team are discussing the benefits of Bumper at the time the booking is taken, in addition to the advisors presenting the option upfront at the point of the Vehicle Health Check, ensuring that customers are made fully aware of flexible monthly payment options from the very beginning. 

“This change means our customers benefit from complete clarity and choice when it comes to maintaining their vehicle, while our teams are empowered to offer a more professional, consistent, and customer-focused experience.” 

This impact has already started to show in their customer feedback, with a 4.9 out of 5 rating on Trustpilot. 

One customer said, “The Service was really good. It was a warm welcome. Dealing with Reece was great.” 

“The whole Bumper finance experience was excellent and extremely user-friendly,” said another. 

Congratulations to Ross, George, Amy, Reece, Jake, Ed, Steve, and the whole team at Listers Audi Birmingham on your win!
