Boiler prices have started rising again in 2026, and this time it’s not down to supply chain issues or inflation alone. Behind the increase is the Clean Heat Market Mechanism (CHMM), a policy that is now beginning to have a visible impact across the UK heating industry. While it’s designed to accelerate the adoption of low-carbon heating, the immediate effect is being felt in a much more direct way: higher costs for gas boilers. Across online discussions, trade forums and posts on X, a consistent theme is emerging. Homeowners are being quoted more than expected for replacements, and engineers are having to explain price increases they didn’t set themselves. Some customers are reporting quotes rising by £100–£300 compared to similar installs just a year ago. What’s driving the increase The CHMM requires boiler manufacturers to meet rising targets for heat pump sales. If they fail to meet those targets, they face financial penalties. In practice, those costs are being built into the pricing of traditional gas boilers. This means: • Manufacturers increase wholesale prices • Merchants adjust pricing accordingly • Install costs rise for the end customer It’s not labelled as a direct tax on invoices, but the effect is the same — higher upfront costs for anyone replacing a boiler. How it’s affecting homeowners: For many households, the timing isn’t ideal. Boiler replacements are rarely planned purchases. They tend to happen when a system fails, often in colder months, when the need

You turn the hot tap on — it’s warm. The boiler fires. Everything looks fine. Then you check the radiators and they’re barely heating. This is one of those faults that seems simple on the surface, but keeps catching engineers out, especially in spring. Across trade discussions and posts on X, a recurring pattern shows up every year: hot water works, heating doesn’t, often after the system has been running hard all winter. The symptoms aren’t always clear-cut. In reality, it’s rarely a complete failure. More often, hot water is only lukewarm, radiators get slightly warm but never properly heat up, or the whole system feels inconsistent rather than fully broken. That’s what makes it easy to misdiagnose. The most common causes, in order of likelihood: First, diverter valve issues. On combi boilers, the diverter valve controls whether heat goes to hot water or central heating. Most commonly, it sticks, only moves partially, or fails to switch fully between modes. The result is that the boiler continues prioritising hot water and the heating side never receives full flow. This is particularly common after winter when the valve has been switching constantly under load. Second, circulation problems. If the boiler is producing heat but it’s not moving effectively, the issue shifts from direction to flow. Common causes include a weakening or sticking pump, partially closed valves, sludge restricting flow, or air trapped in the system. Typical signs are some radiators warming while oth

A call comes in: “The radiators are cold at the top again. I bled them last week and they’re already gurgling.” It’s a familiar pattern for many gas engineers this time of year. The customer expects a quick bleed and move on, but two or three visits later the same complaint returns. Persistent air in the central heating system wastes time, frustrates homeowners, and quietly drives up energy bills through uneven heating and boiler cycling. Trade discussions and on-site reports show this issue cropping up repeatedly in older properties and systems that have seen recent work. Engineers note recurring bleeds on the same radiators, often alongside slight pressure drops or discoloured water. It’s rarely a one-off trapped pocket from initial filling. Most Common Causes Low system pressure and minor leaks top the list. When pressure falls below 1 bar, air is drawn in through any small weakness – often at radiator valves, compression joints on the suction side of the pump, or micro-leaks that don’t show visible water. Refilling via the filling loop introduces more air if not done carefully. Leaks and pressure loss frequently go hand in hand; the system loses water, pressure drops, and air replaces it. Recent system work follows closely. Installing or replacing radiators, flushing, or any break-in to the circuit inevitably introduces air. Even with careful filling, pockets remain in high points or complex pipe runs until the system has run and been bled thoroughly. Corrosion producing

A customer calls at 7am: “The boiler’s on the blink again – pressure’s dropped overnight and there’s no heating.” You’ve been there. By the time you arrive, they’ve already topped it up twice this month. No obvious puddles, no wet patches under the rads, yet the gauge keeps creeping down. This pattern shows up repeatedly on jobs across the UK, especially as systems head into another heating season. Engineers on trade discussions and in the field consistently report the same frustration: repressurising fixes it short-term, but the drop returns, eating into your day and the customer’s patience. Most Common Causes The majority of recurring low pressure cases trace back to water escaping the sealed system. Small, often hidden leaks top the list. These frequently appear at radiator valves (especially older TRVs or lockshield valves that have seen years of operation), joints in pipework buried in floors or walls, or subtle weeping from compression fittings that have worked loose over time. A drip so small it evaporates before you notice can still drop system pressure noticeably over days. Recently bled radiators is the next frequent trigger. Homeowners (or sometimes engineers under time pressure) bleed air from cold spots and forget to repressurise properly, or lose a small amount of water in the process. This one is straightforward but easy to overlook on a busy day. Less Common but Important Causes Faulty pressure relief valve (PRV) . When the PRV seats imperfectly — often after

Every now and then, you get a little nod from the industry that makes all the late nights designing, testing, tweaking and refining completely worth it. Recently, MMPlumber featured two of our tools in his YouTube video: “15 Must-Have Tools Under £25 on Amazon.” Heatlab Ultimate Radiator Key – No.4 Heatlab PlumbShark – No.3 And I just want to take a moment to say how proud that makes us. This wasn’t sponsored. This wasn’t gifted placement. This was simply one tradesman choosing tools he genuinely rates. Why This Means Something If you work in plumbing and heating, you’ll know MMPlumber. He’s built a reputation for straight-talking, practical advice and real-world tool reviews. He’s not hype-driven. He doesn’t sugar-coat things. He calls it how it is. So when someone like that picks up your product and puts it in their “must-have” list, it carries weight. It tells us something important: Tradespeople are actually using our tools. They’re finding them useful. They’re choosing them. That’s everything. The Ultimate Radiator Key – Simple, Done Properly The Ultimate Radiator Key has always been about one thing: solving a small but annoying problem properly. No slipping. No rounding. No fiddly nonsense. Just a key that works on old and new radiators and feels solid in your hand. Seeing it land at No.4 in a trusted top 15 list reinforces what we’ve believed from the beginning — if you refine the basics and focus on quality, people notice.

Why Most Spanners Aren’t Designed for Real Plumbing Work If you’ve spent any time on the tools, you’ll know this simple truth: most plumbing jobs don’t happen in wide-open, comfortable spaces. They happen under boilers. Behind kitchen units. Between pipes, walls, insulation, and awkward fittings that were never designed with access in mind. Yet most spanners on the market are still designed as general-purpose tools. They’re thick, bulky around the jaw, and fine on a bench — but frustrating in real-world installs. At Heatlab, we didn’t start by asking “how do we make another spanner?” We started by asking a better question: What actually makes plumbing jobs harder than they need to be? The Real Problem: Tight Spaces and Thick Spanner Jaws For plumbers, heating engineers, and gas engineers, one of the biggest frustrations is access. When tightening or loosening compression fittings, especially 15mm and 22mm pipework, the spanner jaw is often the limiting factor. Standard spanners are simply too thick around the head to fit comfortably in confined spaces. That’s where most plumber’s tools fall short. You can have all the leverage in the world, but if the tool doesn’t physically fit where you need it — it’s useless. Designing a Better Plumber’s Wrench (Working Backwards) The Heatlab 24mm and 32mm compression spanner set was designed by working backwards from the problem. The goal wasn’t to make a “nice looking” tool. The goal was simple: Create a plumber’s wrench that fits where

ThiefStop by Heatlab: The Alarm That Stops Thieves in Their Tracks Every tradesman knows the feeling — pulling up to the van in the morning and spotting the damage. The handle’s bent, the lock’s been drilled, or worse — the back doors are wide open. Tools gone. Jobs cancelled. Gut-wrenching. I’ve been there myself. That moment when your stomach drops because you realise everything you’ve built your livelihood on — your tools, your gear, your trade — has been taken overnight. It’s infuriating, it’s personal, and it’s expensive. That’s one of the reasons I designed ThiefStop through my company Heatlab , a brand built by British engineers who know what it’s like to work on-site, in the rain, out of the van, day after day. This isn’t another generic alarm. ThiefStop was created out of frustration — because most so-called “van alarms” on the market simply aren’t fit for purpose. Tool Theft: The Hidden Epidemic in the Trades Let’s face the facts. Tool theft in the UK is out of control: In 2023, over 44,000 tool thefts were reported — that’s one every 12 minutes . £98 million worth of tools were stolen in a single year. Over 50% of all thefts happened directly from vehicles — usually vans. The average loss per tradesperson? Around £1,700 , not counting lost jobs or income. The total estimated cost to the trade each year is £264 million once you factor in repairs and downtime. And that’s just what’s reported. Ask around any builder’s yard, electrical wholesaler, or plumbing merchants

Boiler Not Working? Here’s What to Do Before Calling a Professional Boiler Not Working? Here’s What to Do Before Calling a Professional Did you know that over 1.5 million households in the UK experience boiler issues each year? A faulty boiler can quickly turn your cozy home into an uncomfortable space, especially during the colder months. Before you call a professional, there are some simple checks and steps you can take to potentially fix the issue yourself. This guide will help you troubleshoot common boiler problems and get your heating back on track. How to Fix a Boiler That Won't Start 1. Check Your Boiler’s Power Supply Checking the power supply is often the simplest and quickest way to identify boiler issues, as many problems stem from a lack of power. Is the boiler switched on? It might sound basic, but make sure the boiler’s power switch is in the "on" position. Check your circuit breaker. If a fuse has tripped, reset it. If the breaker trips again, there may be an electrical fault. Inspect the power socket. Plug another device into the socket to confirm it’s working correctly. 2. Check the Gas Supply If your boiler isn’t firing up, the problem could be a disrupted gas supply. Inspect other gas appliances. Is your hob or gas fire working? If not, there might be an issue with your gas supply. Check for warning lights. Modern boilers often have indicators for gas supply issues. Refer to your user manual for specific error codes. If you suspect a gas leak, immediately
