Starter Tools for a New Heating Engineer: What I’d Buy First

1. Grips

First on the list for me would be a decent set of grips.

You will use them constantly on radiator valves, pipe fittings, awkward nuts and seized parts. They are also useful when you need to hold one fitting steady while loosening another.

You do not need to go straight for the most expensive pair, but a good set makes a big difference. Cheap grips can slip, chew fittings and make a simple job feel harder than it needs to be.

If you are only buying a few tools to begin with, grips should be right near the top.

2. Adjustable spanner

Next would be a good adjustable spanner.

Heating work involves a lot of different sized fittings, so an adjustable spanner saves you carrying loads of separate spanners when you are just starting out.

You will use it on radiator valves, boiler connections, compression fittings, filling loops and general plumbing work.

A decent adjustable spanner feels better in the hand, gives you more control and is less likely to slip or damage fittings.

3. Radiator and meter cabinet keys

These are two small, inexpensive tools, so I would buy them together and keep both in the same pocket of the bag.

A radiator key is useful for bleeding radiators and dealing with cold spots. A meter cabinet key gives access to common external gas and electric meter boxes when your work requires it.

They are easy to lose, so a spare of each is worth adding later.

4. Pipe benders

If you expect to alter or install copper pipework, pipe benders earn their space quickly.

A good 15mm and 22mm set helps you produce neat bends, reduce unnecessary fittings and keep the finished job looking professional. They are bulkier than the small hand tools, but I would add them before buying lots of power tools.

If you are only servicing and fault finding at first, they may spend some time in the van. If you are doing installations or pipe alterations, you will be glad you bought them.

5. Manometer or U gauge

For gas work, a manometer or U gauge is one of the first proper gas tools I would buy.

It is used for checking gas pressure and carrying out tightness testing as part of safe gas work. It is not something to guess with or treat casually. You need to use it properly and in line with your training and current gas procedures.

If you are newly qualified, this is one of the tools that moves you from general hand tools into proper gas engineer territory.

6. Non contact voltage detector

A non contact voltage detector is a small but important tool.

Heating engineers are often around boilers, pumps, controls, programmers, wiring centres and thermostats. Even if you are not doing major electrical work, you still need to be aware of electrical safety.

A non contact voltage detector is not a replacement for proper safe isolation or correct testing, but it is a useful first check and a handy tool to have with you.

I would still add a proper voltage tester and multimeter later, but as a starter tool, a non contact voltage detector is useful, compact and inexpensive.

7. Temporary continuity bonds

Temporary continuity bonds are another item I would buy early.

When working on pipework, especially around gas or metallic services, maintaining electrical continuity can be important. These are not exciting tools, but they are part of working properly and safely.

They are small, easy to carry and show that you are thinking about safe working, not just getting the fitting apart.

8. Leak detection fluid

Leak detection fluid is a basic but important part of the kit.

It is used to check joints and fittings for leaks where appropriate. For the price, there is no reason not to have it in your bag.

It is one of those simple things you should have available rather than trying to improvise.

9. Screwdriver and bit set, plus Milwaukee Fastback

A good screwdriver and bit set will get used constantly.

Boiler casings, controls, wiring centres, thermostats, pumps, clips and general fixings all involve screws. Cheap bits can round off screws and turn a simple job into a headache, so this is one area where buying decent kit makes sense.

I would also add the Milwaukee Fastback with screwdriver here. It is not a gas specific tool, but it is one of those small everyday tools that earns its place quickly.

You can use it for opening packaging, trimming materials, cutting tape, sharpening pencils, stripping back light materials and doing quick small screw jobs without having to dig through your main tool bag.

Why it matters: a compact screwdriver set covers the proper jobs, while the Fastback is handy for all the small day to day tasks that come up on site.

10. Tool bag and PPE

Once you have started buying tools, you need something decent to carry them in.

A proper tool bag keeps everything organised and helps you arrive ready to work in a customer’s home. PPE is just as important. Gloves, safety glasses and safety footwear should not be treated as optional.

For PPE, buy correctly fitting safety glasses, gloves and safety footwear that suit the work and your employer’s requirements. Fit and comfort matter more than choosing a fashionable brand.

Being organised makes a difference. It saves time, protects your kit and gives customers confidence that you know what you are doing.
