“Are They Gas Safe?” An Engineer’s Guide to Choosing a Heating Professional You Can Actually Trust

---

“Are They Gas Safe?”

Let’s talk about trust. When you let someone into your home to work on a gas appliance, you are placing an enormous amount of trust in their hands. You’re trusting them with the safety of your property, your belongings, and most importantly, your family.

In my line of work, I often follow in the footsteps of others. Sometimes I see fantastic work, a real credit to the trade. Other times, I see things that make my blood run cold: dangerous installations, botched repairs, and work done by people who have no right to be touching a gas appliance. The scary part is that to the untrained eye, it can be hard to tell the difference until it’s too late.

So, how do you, as a homeowner or landlord, find an engineer you can truly trust? The answer starts and ends with three simple words: Gas Safe Register.

This isn’t just a badge or a sticker on a van. It is the only official, legal register of gas engineering businesses in the United Kingdom. If someone is not on that register, it is illegal for them to carry out gas work in your home. Full stop.

This guide will explain what Gas Safe registration really means, how to verify it, and the red flags that should send you running for the hills.

What is the Gas Safe Register?

The Gas Safe Register is the official list of businesses that are legally permitted to work on gas appliances. It replaced the old CORGI scheme back in 2009. It’s not a trade association or a recommendation service; it is a legal requirement enforced by the Health and Safety Executive (HSE).

To be on the register, an engineer must hold relevant, in-date qualifications for the specific type of gas work they want to carry out. These aren’t qualifications you get once and have for life. We have to be reassessed every five years to prove we are still competent and up-to-date with the latest regulations and safety procedures.

The Gas Safe ID Card: Your Proof of Competence

This is the most important tool you have to protect yourself. Every single registered engineer is issued with a Gas Safe ID card, and they are legally required to carry it when they are working.

Don’t be shy or feel awkward about asking to see it. Any legitimate, professional engineer will be happy and proud to show you their card. In fact, we expect you to ask. If an engineer gets funny about showing you their card, that is a massive red flag. Show them the door.

How to Read the ID Card: The card contains vital information:

1. The Photo and Name: To confirm the person at your door is who they say they are.
2. The Licence Number: A unique 7-digit number for that specific engineer.
3. The Expiry Date: To ensure the card is still valid.
4. The Security Hologram: To prove the card is genuine.
5. The Back of the Card (Most Important): This is where you see what the engineer is actually qualified to do. Gas work is not a one-size-fits-all qualification. An engineer might be qualified to work on a gas boiler, but not a gas fire or a cooker. The back of the card lists the specific appliances they are competent to work on. If they are there to service your boiler, you must see “Gas Boilers” listed.

How to Verify an Engineer – The 30-Second Check

You don’t just have to take the card at face value. You can verify any engineer in less than a minute.

• Online: Go to the Gas Safe Register website (gassaferegister.co.uk) and use their “Check an Engineer” tool. You can search by their 7-digit licence number or by their business name.
• By Phone: You can call the Gas Safe Register directly on 0800 408 5500.

This simple check gives you complete peace of mind.

The Dangers of Illegal Gas Fitters

Using an unregistered person isn’t just a bit risky; it’s potentially deadly. The work they do is not inspected, not insured, and often not safe. I’ve seen flues that are not sealed properly, leaking carbon monoxide back into a home. I’ve seen gas connections that are not tight, creating a slow but steady gas leak.

These people are not “a bit cheaper”; they are a gamble with your family’s life. Saving £50 on a boiler service is not worth it when the consequences can be a house fire, an explosion, or carbon monoxide poisoning.

Furthermore, any work they do will invalidate your home insurance and your boiler’s warranty. If something goes wrong, you are completely on your own, financially and legally.

Beyond the Card: What Does a True Professional Look Like?

Being Gas Safe registered is the legal minimum. It’s the entry ticket. But what separates a good engineer from a great one?

• They Provide a Quote: For any significant work, they will provide a clear, written quote detailing the work to be done and the costs involved.
• They Have Insurance: They will have public liability insurance to cover any accidental damage to your property.
• They Stand by Their Work: A reputable company will offer a workmanship warranty on their repairs and installations.
• They Have a Reputation: Look for them on trusted review sites like Checkatrade or Google. A long history of positive, verifiable reviews is a strong sign of a trustworthy business.
• They Communicate: They will explain what they are doing, show you any faulty parts, and answer your questions clearly.

Your home’s heating system is a major investment. The person you entrust to work on it should be a qualified, insured, and reputable professional. The Gas Safe Register is your first and most important line of defence. Use it.

The “Gas Boiler Ban”

The “Gas Boiler Ban”: An Engineer’s Unbiased Guide for Worried London Homeowners

Let’s clear the air. Over the past few years, the headlines have been dramatic: “Gas Boilers to be Banned!”, “Say Goodbye to Your Heating!”. As an engineer on the front line, I’ve had countless worried customers in London asking me if they’re going to be forced to rip out their perfectly good boiler.

The short answer is no. But the long answer is more nuanced, and it’s important to understand what’s really happening with UK heating policy, away from the confusing headlines. This isn’t about politics; it’s about giving you the practical, on-the-ground facts so you can make smart decisions for your home over the next decade.

First, Let’s Demystify the “Boiler Ban”

What the government has actually announced is a plan to phase out the installation of new gas boilers in new-build properties only, starting from 2025. This means that houses built from scratch after that date will likely be fitted with alternatives like heat pumps.

For the 25 million existing homes in the UK with gas boilers, the situation is completely different. The government’s ambition is to phase out the installation of new fossil fuel boilers sometime after 2035.

Let me say that again, because it’s the most important point: No one is coming to take your boiler away. Your existing gas boiler is not being made illegal. You can, and absolutely should, continue to service and repair it to keep it running safely and efficiently for its full natural lifespan. This policy is about what happens in over a decade’s time when your current boiler eventually needs replacing.

The Engineer’s Reality Check: What About Heat Pumps?

The government’s preferred replacement is the air source heat pump. You’ve probably seen them—they look like air conditioning units on the side of a house. In the right property, they are a brilliant piece of technology. They work a bit like a fridge in reverse, using a refrigerant cycle to absorb heat from the outside air (even when it’s cold) and transfer it into your home’s heating system.

However; and this is a big however, they are not a simple “plug-and-play” replacement for a gas boiler, especially in London.

1. The Insulation Issue: Heat pumps work best in homes that are incredibly well-insulated and airtight. They produce heat at a much lower temperature than a boiler (around 40-50°C compared to a boiler’s 60-70°C). In a draughty Victorian terrace, a lot of that gentle heat will simply escape before it has a chance to warm the room. To make a heat pump effective, you often need to invest thousands of pounds first in solid wall insulation, new double-glazing, and comprehensive draught-proofing. For many London properties, this is either financially prohibitive or restricted by planning regulations.
2. The Radiator Issue: Because the water they produce isn’t as hot, heat pumps often require much larger radiators to provide the same level of warmth to a room. This can mean replacing most of the radiators in your house, adding significant cost and disruption.
3. The Cost: While government grants are available, the upfront cost of installing a heat pump system is still significantly higher than a new gas boiler, often two to three times as much.

For a modern, well-insulated new-build, a heat pump makes perfect sense. For a 150-year-old London property, it’s a far more complex and expensive proposition.

So, What’s the Smart Choice for the Next Decade?

Given the realities of London’s housing stock and the current costs, the strategy for the next 10-15 years is clear. It’s about bridging the gap between today’s proven technology and whatever comes next.

• The Rise of “Hydrogen-Ready” Boilers: The gas industry is preparing for a potential future where the natural gas in our pipes is replaced with low-carbon hydrogen. As a result, almost all new A-rated gas boilers being installed today are “hydrogen-ready.” This means they are designed to run on the current gas supply but can be converted to run on 100% hydrogen with a simple, one-hour component swap by an engineer in the future. Installing one of these is the ultimate no-regrets move.
• Efficiency is King: For now, the most practical, reliable, and cost-effective way to heat the vast majority of London homes is with a high-efficiency A-rated gas boiler. These models are over 90% efficient, meaning less than 10p of every pound you spend on gas is wasted. Paired with a smart thermostat, they offer incredible control and low running costs.
• Maintenance is Your Best Investment: The smartest and most economical thing you can do is to keep your current boiler running as safely and efficiently as possible. An annual service is not just a “check-up”; it’s an essential tune-up that ensures you’re getting the most heat for your money and extends the life of your appliance, allowing you to make the decision to upgrade at a time that suits you, not in a panic.

Don’t let the headlines cause you anxiety. The future of home heating is a gradual transition, not an overnight switch. For the foreseeable future, gas boilers will remain the heart of most London homes. The key is to ensure yours is as efficient, safe, and reliable as it can be.

5 Ways Your Boiler Is Secretly Costing You Money (And How an Engineer Can Fix It)

Your Boiler Is Secretly Costing You Money

With energy bills being one of the biggest household expenses, we’re all looking for ways to save money. We switch off lights, turn down the thermostat, and layer up with jumpers. But often, the biggest culprit for wasted energy and high bills is humming away quietly in a cupboard: your boiler.

An inefficient or poorly maintained heating system can be secretly siphoning money out of your bank account every single day. As an engineer, I see it all the time, homes that are haemorrhaging cash simply because their boiler isn’t being allowed to do its job properly.

Here are five of the most common ways your boiler is costing you money, and the professional fixes that can make a real difference to your bills.

1. You’re Skipping Its Annual Service

Let’s start with the most important one. An un-serviced boiler is an inefficient boiler. Over a year of operation, dust can build up, injectors can become partially blocked, and key components can drift out of their optimal settings.

• The Problem: The boiler has to work harder and burn more gas to produce the same amount of heat. It’s like driving a car that hasn’t had an oil change in years, it will still run, but it’s guzzling fuel and damaging the engine.
• The Fix: An annual boiler service is the solution. A Gas Safe engineer doesn’t just check for safety; we perform a full tune-up. We clean components, check gas pressures, and use a flue gas analyser to ensure the fuel-to-air mixture is perfect. A properly serviced boiler can be up to 10% more efficient, which is a direct saving on every bill.

2. Your Radiators Are Full of Cold, Expensive Sludge

Do you have radiators that are cold at the bottom, even when the heating is on full blast? That’s not just a minor annoyance; it’s a major sign of inefficiency.

• The Problem: Over the years, the inside of your pipes and radiators corrodes, creating a thick, black, metallic sludge. This sludge settles at the bottom of your radiators, blocking the flow of hot water. Your boiler has to run for longer and at higher temperatures to try and force heat into the room, wasting huge amounts of gas in the process.
• The Fix: A Power Flush. This is a deep-clean for your entire central heating system. We connect a powerful pump and use special chemicals to break down and flush out all the years of accumulated sludge. The result? Your radiators heat up quickly and evenly, and your boiler can run at a lower, more efficient setting, saving you money.

3. You’re Using “Dumb” Controls

If you’re still using a simple dial thermostat on the wall, you’re living in the dark ages of heating control. These old analogue thermostats can be inaccurate by several degrees.

• The Problem: An inaccurate thermostat means your boiler is either firing up when it doesn’t need to or not shutting off when the room is already warm enough. You’re paying to overheat your home.
• The Fix: Upgrade to a smart thermostat (like Nest, Hive, or Tado). These modern controls are incredibly accurate and allow you to set detailed schedules from your phone. They also have clever features like “geofencing,” which automatically turns the heating down when you leave the house and back on when you’re on your way home. The Energy Saving Trust estimates that a smart thermostat can save a typical home over £100 a year.

4. Your System Is Unbalanced

Does the radiator in your living room get scorching hot while the one in the spare bedroom stays lukewarm? This is a sign of an unbalanced system.

• The Problem: Hot water, like all things, follows the path of least resistance. In an unbalanced system, most of the hot water is rushing to the nearest radiators, while the ones further away are starved of heat. To get that cold bedroom warm, you have to turn the thermostat up, overheating the rest of the house and wasting energy.
• The Fix: Radiator Balancing. This is a simple job for an engineer. We adjust the lockshield valves on each radiator to control the flow of water, ensuring every radiator in the house heats up at the same even rate. It’s a small adjustment that makes a big difference to both your comfort and your bills.

5. It’s Simply Too Old

This is the hardest one to hear, but it’s the most important. If your boiler is over 15 years old, it is costing you a fortune.

• The Problem: A boiler from that era might have a G-rated efficiency of 70% or less. A brand-new, A-rated boiler is over 90% efficient. That 20% difference is pure waste. For every £100 you spend on gas, an extra £20 is vanishing into thin air compared to a modern boiler. That can add up to hundreds of pounds a year.
• The Fix: Boiler Replacement. While the upfront cost is significant, a new boiler is an investment that pays for itself over its lifetime through lower energy bills, higher reliability, and a long manufacturer’s warranty.
