Later this year passengers in the UK could be booking rides in cars with no one behind the wheel and the government is pushing ahead fast. 

In May, applications opened for operators to run self-driving taxi and bus-style services across Great Britain as part of a new pilot scheme.  

Companies including Uber and Waymo, which already completes over 500,000 autonomous rides every week across eleven US cities, have signalled their intention to bring services to UK roads this year, with London expected to be the first city to see them in action. 

Safety is at the centre of the rollout. Operators must pass strict government approval checks before any passenger sets foot in a self-driving vehicle, including assessments to ensure the technology is protected against cyber threats.  

The self-driving technology could significantly improve road safety, with human error currently contributing to 88% of collisions on UK roads. 

The bar for safety is being set deliberately high. Self-driving vehicles will need to demonstrate a higher safety standard than the average human driver before they can be approved for everyday use.  

Members of the public, road safety groups and accessibility organisations are all being invited to have their say, with a consultation open until 9 September 2026. 

Beyond safety, the government believes the technology could open up independent travel for older and disabled people who currently struggle to access transport and estimates the sector could be worth £3.7 billion annually in Britain by 2040, supporting thousands of skilled jobs in the process.

Driverless cars are almost here – are you ready? 

New analysis has revealed that potholes are responsible for up to 1.7 million MOT failures every year – a figure that will come as little surprise to anyone who regularly navigates Britain's crumbling roads. 

Using DVSA data, The Sun analysed 2.5 million MOT failure points typically associated with pothole damage across 1.74 million cars. 

Over 1.1 million suspension arms and ball joints were found to be damaged, 882,000 springs had snapped, and 450,000 shock absorbers were ruined.  

Two-thirds of all these failures were concentrated in the front wheels – the first point of contact when a car drops into a ditch.  

However, not all failures will have been caused solely by potholes. Natural wear and tear may have also played a role in the MOT failure. 

Birmingham topped the list of pothole damage hotspots, with 34,758 cars failing their MOT with faults commonly linked to road surface damage. Sheffield came second with 33,896 failures, followed by Nottingham, Glasgow and Cardiff. 

Until the roads improve, the best defence is knowing how to drive around the problem.

1.7m MOT failures are down to potholes – Here's what to do

Bumper, the automotive payments platform, today announced the launch of Myles, a GenAI assistant built into its dealership intelligence platform, AutoBI. Myles is now being rolled out to a selected group of pilot dealer customers, marking a major step forward in how car dealerships and OEMs access and act on their data.   

Myles enables leaders and teams across dealerships to request performance analysis using natural language, and to receive insights grounded in their own AutoBI data. The assistant ships with a curated set of questions covering the metrics dealer groups review most frequently. Users can also ask anything they need to understand trends and dive deeper into performance metrics and specific verticals. 

Myles’ insights can be accessed through chat or delivered in a range of formats, including written summaries, board packs, and daily audio or video briefings tailored for senior leaders on the move. Myles empowers all users within a dealership, democratising analytics and helping users make faster and smarter decisions. 

AutoBI is a real-time insights platform used by dealer groups and manufacturers across the UK and Europe. Since joining the Bumper family, AutoBI has unlocked deeper visibility and thousands of dynamic reports that help partners drive profitability, sharpen efficiency and cut operating costs.  

Myles extends that platform by enabling users to create insights on demand using the underlying data conversationally and to receive role-specific answers without building custom reports. Bumper is now inviting forward-thinking dealer groups to join its advanced pilot programme and help shape the future of AI-driven performance insight. 

Pasha Jam, Chief Technology Officer at Bumper, said: “AutoBI has already reshaped how dealer groups understand their performance, and the development of our AI tool, Myles, pushes that transformation even further. By turning complex, real-time data into clear, role-specific intelligence, we’re giving teams across the dealership the ability to make smarter decisions, faster. This is a major step forward for automotive retail, and we’re excited to work with progressive dealer groups through our pilot programme to drive a new era of AI-led operational excellence.”

The Skoda Octavia has long been considered one of the smartest buys in the family car segment, combining Volkswagen Group engineering with strong practicality and low running costs. 

But Skoda reliability depends heavily on which generation you’re looking at.

The latest Mk4 (2020–2024) model is more advanced and refined than ever, but it also introduces more complex electronics that have slightly affected its reliability reputation compared with its predecessor.

Overall, the Octavia remains a solid, dependable choice, but it is no longer the “bulletproof” class leader it once was. Find out more about the Skoda Octavia reliability and common problems in 2026 below.

Overall Skoda Octavia reliability verdict

The Skoda Octavia sits in a mixed but still above-average reliability position in the family car class.

Older models (particularly the 2013–2020 Mk3) built a strong reputation for durability and even topped reliability rankings in several surveys. 

However, the newer Mk4 generation  (2020–2024) has slipped slightly due to increased reports of:

In recent reliability surveys, the Octavia has shown a noticeable split between mechanical strength and electronic fragility. This means the engine and chassis are generally solid, but software and electronics are the weak point.

Common problems by Skoda Octavia generation

The Skoda Octavia’s reliability record varies significantly by generation, with issues ranging from ageing mechanical wear in early models to software and electronic faults in newer versions.

Let’s review the problems from newest generation to oldest.

The latest generation Skoda Octavia is the most advanced version yet, but also the most complex, and that added complexity has introduced a new set of potential weak points. 

While the core mechanical components remain strong, most reported issues are now centred around electronics, software, and transmission behaviour rather than fundamental engineering faults.

As you can see above, the most common Mk4 Octavia issues relate to infotainment faults, including frozen or slow screens, navigation errors, and system reboots. The DSG gearbox can also show low-speed hesitation and jerky shifts, especially in traffic. 

Some owners report minor electrical niggles, such as sensor warnings and battery drain. Less frequently, water pump and cooling system issues occur, potentially leading to coolant leaks and overheating if not addressed early.

Lastly, several Mk4 models have been subject to recalls, typically involving plug-in hybrid electrical components, minor assembly issues, or items such as loose engine covers. These are generally resolved under warranty.

 Very capable, but electronics reduce perceived reliability.

This generation significantly improved refinement and reliability, and is still considered one of the best used buys. 

Despite these, many owners report strong long-term durability if maintained properly. Bumper always recommends looking at the car’s service history before buying used, though.

 One of the most reliable modern used family cars.

Mk3 (2013–2020 facelift overlap context)

Often rated the strongest overall Octavia generation for reliability, covering both pre and post-facelift models (2013–2020), where the mid-life update introduced minor improvements but the core engines and platform remained largely unchanged.

Many reliability surveys placed this generation near the top of its class, with consistently strong scores driven by its proven mechanical parts, relatively simple electronics compared with newer models.

 Benchmark reliability for the nameplate.

The earliest Skoda Octavia models are generally regarded as robust and mechanically simple, with a reputation for solid Volkswagen Group engineering underneath, but at this age most examples are now more affected by wear-and-tear and age-related degradation than inherent design flaws.

Overall, while major mechanical failures are not especially common if the car has been well maintained, running costs tend to rise with age as multiple smaller components begin to fail more regularly and maintenance becomes more frequent.

 Mechanically durable, but now aged and maintenance-heavy.

Typical Skoda Octavia repair costs (UK Prices)

While most Octavia issues are not catastrophic, repair costs vary depending on drivetrain and fault type. 

Here are some approximate Skoda Octavia repair costs based on common problems in 2026.

As you can see, electronic and gearbox-related issues are the most expensive risks. You can use

Owner satisfaction summary for the Skoda Octavia

Owner satisfaction with the Skoda Octavia is generally positive, but with clear generational differences. Here’s the outlook for those on the fence.

Strengths consistently highlighted in Skoda Octavias:

Common frustrations for Skoda Octavia owners:

The Mk3 generation remains the most loved by owners due to its simplicity and durability, while the Mk4 is seen as more advanced but less “set and forget.” 

And the older models? They’re durable but clearly aging in comparison to competitors.

The Skoda Octavia remains one of the smartest family car choices on the market, but its reliability story has evolved since 2020. If you want maximum peace of mind, the Mk3 is still the safest bet. If you want the latest tech and refinement, the Mk4 delivers, but just expect a higher chance of minor electronic issues.

Skoda Octavia Reliability Guide & Common Problems (2026)

Skoda Octavia Reliability Guide

Because catalytic converters contain precious metals such as platinum, palladium and rhodium, they can cost anywhere from £400 to £2,000 or more to replace. 

Thanks to Euro emissions regulations, catalytic converters have been essentially mandatory on all petrol cars since 1993, and all diesel cars since 1997. There are two main reasons why catalytic converters would need to be replaced: deterioration and theft. We'll cover costs for both in this article.

How much does it cost to replace a catalytic converter?

Like most vehicle parts, catalytic converters vary in price depending on the age, type and model of the car. The table below shows some indicative prices. A large factor is whether you replace it with an OEM part or an aftermarket part.

Alongside the usual effect of premium brands charging more for parts and labour, there are a number of other factors that affect the price you pay for a replacement catalytic converter. 

OEM stands for original equipment manufacturer, or in other words, the parts are made or at least sold by the same company that makes the cars themselves. This generally means the parts of higher quality, but come with a larger price tag. 

Aftermarket parts, sometimes referred to as pattern parts, are made by independent manufacturers, using broadly the same designs and specifications as the original.

Depending on the brand, aftermarket parts can be either as good as, or far worse than, the OEM parts in quality, consistency and longevity. 

As catalytic converters ordinarily last a long time, it can be feasible to replace them with a second-hand part from a breaker or dismantler. This usually comes at a much lower cost, but often without any guarantee. 

Some garages will not fit secondhand parts, due to the complications that arise if the part were to fail prematurely. 

Often sold as performance upgrades for vehicles, so-called "sports cats" are often cheaper than the OEM or aftermarket OEM-equivalent, but claim to be just as effective. 

The main selling point is often that they allow less air flow restriction, enabling higher performance from the engine.

As with any car part, the long term performance will depend on the quality of the particular part, but oftentimes the consensus on sports cats is that they work on reducing emissions for a period of time, but deteriorate after a few years. 

High performance cars or those with large engines, typically burn more fuel to create more horsepower than an equivalent run of the mill car. Despite this, they still need to meet the same emissions levels. 

To accomplish this, manufacturers make the catalytic converters larger, and with more precious metals inside. This makes them more expensive to manufacture.

Hybrid cars also tend to have larger catalytic converters than purely petrol or diesel vehicles. Because a hybrid engine switches off and on rather than running continuously, the catalytic converter never stays fully up to temperature – and cats work least efficiently when cold. To compensate for these repeated cold-start emissions spikes, hybrids need a larger, more capable unit.

Do diesels have catalytic converters or DPF filters?

Diesel cars made after 2015 and sold in Europe, will have both. Almost all diesel cars have been fitted with catalytic converters since the late 1990s in order to meet emissions regulations. 

Diesel catalytic converters do not work on the same chemical principle as petrols but still serve to remove harmful pollutants, alongside DPF filters, that work to reduce harmful particles of soot. 

Catalytic converter theft and how to prevent it

Because catalytic converters are full of precious metals, their scrap value can be quite high. Depending on global markets, certain converters can be worth upwards of £800. 

This coupled with the fact many are easily accessed from under the car, makes them a target for thieves.

There are a few methods to help prevent your catalytic converter from being stolen:

What to do if your catalytic converter gets stolen

The first thing you are likely to notice when your catalytic converter has been stolen is that the car’s exhaust will be incredibly loud.

It's important to not drive the car in this state without being inspected, as the remaining exhaust could catch the road, causing further damage, not to mention the harmful fumes that are likely to enter the car.

Take photos, and make notes of when the theft is likely to have occurred. It may also be worth speaking to neighbours or close by businesses who have CCTV or doorbell cameras. 

Report the theft on the non emergency phone number, detailing all the particulars. This is likely to be necessary to claim the cost from your insurer

Ring your insurance company, and explain the situation. They will likely open a claim, and start the process of collecting information and discussing next steps with you.

Catalytic Converter Replacement Cost – UK 2026

Catalytic Converter Replacement Cost

Water pump replacement typically costs between £350 and £900 in the UK, depending on the make and model of the car and what type of garage you take it to.  

In this article, we’ll take a look at some factors that affect water pump replacement costs, when you need to get it done, and timing belt considerations. 

What affects water pump replacement costs?

Like any repair job, there are many factors that affect the cost you pay:

Parts costs vary greatly between brands. For luxury marques such as BMW and Mercedes, parts are in some cases 40-70% more expensive than others. 

Whilst there are different levels of part quality, it’s generally recommended to go for a high-quality water pump, as it is so integral to the engine's reliability.

If your car has a particularly high-tech, large or sporty engine, the chances are access will be limited, meaning the mechanic has to spend more time removing parts, and therefore higher labour costs.

On engines with timing belts, changing the water pump usually comes with the added cost of a new timing belt kit. On chain-driven engines, they are usually separate, lowering the cost.

Main dealer labour rates are usually much higher than those of independent garages; they will also want to use only dealer-sold parts. On the other hand, dealer work invoices are likely to hold more value at resale or trade-in.

An independent specialist will often give you the best combination of expertise and price, offering cost-effective ways to repair your car, without compromising on quality.

What happens if you put off repairing a water pump?

Nobody likes spending hundreds on car repairs, so it's understandable that you may want to put off replacing a water pump, but not doing so could land you with a much larger bill in the near future.

The most common reason water pumps need replacement is when they are leaking. This means the engine's coolant level is constantly dropping. Unless you are meticulous with checking and topping up your coolant (including making sure the concentration is correct), it is easy to let your car run low. 

Running an engine for even a minute or two without sufficient coolant can cause damage, ranging from blown head gaskets to warped engine blocks.

Should I replace the timing belt when doing a water pump?

It usually makes sense to fit a new timing belt kit when doing a water pump, as the extra parts cost is usually outweighed by the extra labour time incurred by doing each job separately. 

This is because on most engines with a timing belt, the water pump is driven by the timing belt. Meaning in order to replace the water pump, the engine has to be locked, the timing belt removed, and then replaced afterwards. 

With a new timing belt being around £50-£150, unless your car has had a new belt fitted very recently, it makes sense to simply replace it with a new one. 

Should I replace the water pump when doing a timing belt?

It makes sense to replace the water pump when doing a timing belt, as the two jobs share many of the same steps to replace. 

A replacement water pump generally costs between £50 and £100, so it ends up being a fraction of the total cost, for the peace of mind of a major servicing item being sorted early.

Repairing a blown head gasket can be expensive, even on a mid-level vehicle. Audis are generally considered to be more expensive to repair thanks to higher parts and labour costs.

In this article, we’ll take a look at how much you should expect to pay to repair a head gasket issue on an Audi A4, a very popular model in the UK. We’ll cover best and worst-case scenarios, as well as include some tips for what to do if you think your head gasket is failing. 

Replacing the head gasket on an Audi A4 can cost anywhere from £800 to £2,000, depending on the extent of the damage, the exact model of A4, and the type and location of the garage used. 

If your Audi is a performance model or has a complex engine, such as the 3.0 V6, the time and expertise needed to repair it are likely to be higher. Expect to pay at least £1,600 to replace both head gaskets on a V6-engined A4.

Another factor is how soon you can catch the issue. If you continue to drive with a blown head gasket, overheating is likely to occur, which can easily cause significant damage to the engine head and block.

Whilst Audis benefit from the same reputation as most German brands, quality engineering and reliability, they are generally more expensive than the average car to repair. This is thanks to both higher parts costs and higher labour rates. 

However, the A4 is a premium saloon, and competes with models such as the BMW 3 Series and Mercedes C-Class. When compared to these types of cars, repair costs are on par, with Mercedes typically being higher, and BMW around the same, especially at main dealer garages.

This depends on the age, model and condition of the car; a nearly new car that’s still worth 80% of the retail price would be economical to repair. On the other hand, a 15-year-old car that’s only worth a few thousand when repaired is probably not worth spending £1,000-£2,000 on.

Another thing to consider is how much the repair is likely to cost in total, and what other parts may also be replaced at the same time. In many cases, major work such as replacing a head gasket requires removing and refitting the timing chain, water pump and other major service items. 

Whilst this does increase the repair cost, it may well make for a slight saving over doing the jobs separately, and can make the car worth more after the work is complete. 

An engine is made up of two main components, the block and the head. The block contains the cylinders and pistons, and the head acts as a cap to the cylinders, retaining the combustion pressure. 

The head gasket is a sealing material between the head and the block. Deterioration over time, a manufacturing issue, or an overheating problem can cause leaks from the gasket. 

There are a few different ways a head gasket can blow, such as allowing coolant or oil into the combustion chambers, or blowing between two cylinders. All these failure modes will cause issues with running, overheating and more. 

Can I still drive with a bad head gasket?

No, it’s highly recommended not to continue to drive a car with a damaged head gasket. This is because any symptoms will be worse, as well as risking overheating the engine, if the coolant is being burned in the cylinders. 

An engine that has a blown gasket and has overheated will require even more work to make it good, potentially meaning a new engine head or block is needed. To reduce costs, it’s best to get a head gasket repaired as soon as possible. 

What are some symptoms of a blown head gasket?

Because the gasket is integral to the engine, retaining the combustion pressure, oil and coolant, there are numerous telltale signs of a damaged head gasket:

This spring bank holiday was the hottest on record.  While the sun may be perfect for enjoying a few mojitos on the garden there’s one thing it’s not good for – driving. 

With temperatures recorded as high as 34.8°c at Kew Gardens in London this weekend, there’s sure to be a few overheated drivers getting behind the wheel over the coming days. 

To help keep you cool on the road this summer we have a science-backed method that will cool your car down in seconds. 

Scientific hack for keeping your car cool in hot weather 

The simple yet effective method works like this. Open the passenger side window and rapidly open and shut the driver’s-side door two or three times, using bulk flow and fluid dynamics the wafting motion of the door will pull cooler air through the cabin. 

For extra cooling, open both windows on the passenger side to allow more cool air through the car.  

To avoid injury, make sure to park in an area clear of traffic and check the path isn’t being used by pedestrians. 

5 more tips for keeping your car cool in summer 

If standing in the street and fanning your door isn’t for you, here are 5 more tips to keep your car cool in hot weather. 

Blankets may seem like something you only use in winter, but you can use them in sunny weather to keep your seats cool.  

Leaving blankets on the seats while the car isn’t in use can absorb heat and keep your driving experience cooler. 

When you’re ready to start your journey, simply throw the blankets in the boot and you’re good to go. 

Consider keeping a bottle of water in the car to cool down your steering wheel, gear stick and seatbelt buckles. In the hot weather, the water will evaporate quickly, taking much of the heat with it. 

Remember to dry off the the steering wheel before setting off to ensure you can get a good grip of it. 

Leaving your windows open a crack will help to ventilate the inside of the cabin while the car is not in use, keeping it much cooler. 

Make sure to only leave the windows down less than the width of a person’s arm to deter thieves and check the weather forecast for rain. The last thing you want to come back to on a hot day is a wet car seat! 

Did you know it only takes about 60 seconds for carbon dioxide to disperse once you open the door? If you leave your car for around a minute before getting in, you’ll be sure to have a much cooler start to your journey. 

If you have leather seats, cotton seat covers can be a great way to prevent heat building up. Leather seats can take around two hours to fully cool down but the cotton alternative is much faster. Covers can be found on Amazon for as low as £14.
