VanlyYou have gone out on your own, you are Gas Safe registered, and the phone is ringing. Then a landlord asks your hourly rate and you freeze. Search how much should a gas engineer charge per hour in the UK and every result hands you the same shrug: somewhere between £50 and £90. None of them asks the question that actually decides whether this works, which is how much you need to charge to make a living once the van, the tax and the registration are paid for. Here is that number, and the maths to find it yourself.

What gas engineers actually charge in the UK in 2026
Start with the market, because you do need to know it, then we move past it fast.
Here is the rough shape of UK gas engineer pricing in 2026, pulled from the cost guides customers read before they ring you.
| Type of work | Typical rate 2026 |
|---|---|
| Standard domestic hourly, national average | £50 to £90 per hour |
| North of England and Wales | £45 to £70 per hour |
| London and the South East | £70 to £120 per hour |
| Day rate, install work | £250 to £450 per day |
| Boiler service, fixed price | £80 to £150 |
| Landlord gas safety record, CP12 | £60 to £120 |
| Emergency or out of hours | £90 to £150 per hour |
| Call out or minimum first hour | £70 to £130 |
Those figures line up with the public cost guides that rank for this search, the London price pages, the "how much does a gas engineer cost" guides, and the employed salary trackers. They are accurate enough as a market picture.
They are also close to useless to you as the person kneeling at the boiler. Every one of those numbers answers the customer's question, which is what will a gas engineer cost me. It does not answer your question, which is what do I need to charge so I am not quietly earning less than an employed engineer with a pension by the time the year is out. Those are not the same number. They are not even close.
Why the market rate is the wrong place to start
The going rate is a price customers pay. It is not money you keep.
Out of every hour you bill at £70, you do not bank £70. You bank what is left after income tax, National Insurance, the van, the diesel, the flue gas analyser and its calibration, the spares you carry, the public liability cover, your Gas Safe registration, the accountant, and the hours that week you worked but could not put on an invoice. By the time all that comes off, a £70 hour is worth a lot less than £70, and most people who have just gone out on their own have never sat down and worked out how much less.
How much you keep also depends on how you are set up. A sole trader and a limited company keep very different slices of the same turnover once tax is in the picture, which is the sole trader vs limited company question. Picking your hourly rate by copying the going rate is like quoting a boiler swap by guessing. You would never do that on a job. Do not do it with your own pay.
The right way round is to start from the money you want to take home, then work backwards to the rate that delivers it.
The billable hours trap
This is the one that catches almost every newly self employed gas engineer, and it is worth slowing down for.
There are about 2,080 working hours in a full time year. Most people, asked to set an hourly rate, quietly assume they will bill most of those. You will not. Not even close.
You do not bill the hours you spend quoting a full heating system. You do not bill the drive between calls, the trip to the merchants for one diverter valve, the half day waiting on a boiler delivery, the evening doing invoices, the Saturday chasing a letting agent who has gone quiet. You do not bill the 5.6 weeks of holiday and bank holidays an employee gets and you quietly skip, the week you were off with a bad back, or the days you lose to your ACS reassessment and your Gas Safe renewal.
Gas work has one extra twist that plumbing and sparky work do not, and it makes this worse. Your year is lumpy. You are flat out from October to February when every boiler in the country decides to pack in, and slower through the summer when the only calls are services and the odd landlord cert. If you set your rate off how busy you feel in January, you will underprice for the eight months that are not January.
Add it up and a solo domestic gas engineer bills somewhere between 1,100 and 1,300 hours in a year, not 2,080. Every hour in that unbilled pile still has to be paid for. It gets paid for by the hours you do bill. Which means your rate has to carry the cost of the hours it cannot.
Work out your own number in five steps
Here is the maths the cost guides skip. Use round numbers and your own figures. This is a worked example, not a promise, and your numbers will be different.
Step 1. Decide your target take home. What do you actually want in your pocket for the year, after everything. Say £40,000. Pick your own.
Step 2. Gross it up for tax and National Insurance. To take home roughly £40,000 as a sole trader you need to make somewhere around £53,000 in profit, give or take, before income tax and Class 4 NI. The exact figure depends on your structure, which is the sole trader vs limited company question again.
Step 3. Add your business overheads for the year. A fairly lean solo gas engineer setup looks something like this:
| Overhead | Rough annual cost |
|---|---|
| Van: lease or finance, fuel, insurance, servicing | £6,000 |
| Gas Safe registration | £400 |
| ACS reassessment, spread across its five year cycle | £150 |
| Flue gas analyser calibration and test equipment | £300 |
| Tools and replacement kit | £1,200 |
| Public liability and professional indemnity insurance | £550 |
| Training and CPD | £400 |
| Accountant | £900 |
| Phone, software and general admin | £700 |
| Total | about £10,600 |
The Gas Safe registration line is not optional the way a scheme membership is for a plumber. No registration, no legal gas work, so it is a fixed cost of being in business before you turn a single valve. The analyser calibration and the ACS block are the same. Build them in.
Step 4. Add it together. £53,000 of profit plus £10,600 of overheads means you need to invoice about £64,000 in the year just to land where you wanted to be.
Step 5. Divide by the hours you will actually bill. Not 2,080. Use a realistic billable figure.
| Billable hours in the year | Rate to hit £64,000 |
|---|---|
| 1,400 hours (a strong heating season carries the year) | about £46 per hour |
| 1,200 hours (steady solo year) | about £53 per hour |
| 1,000 hours (quiet summer, lots of small services) | about £64 per hour |
Look at what that table is telling you. The £50 the bloke down the road quotes only works if you bill 1,400 hours, which a solo domestic gas engineer manages only in a big year with the diary packed and the admin under control. At a realistic 1,200 billable hours, your floor is closer to £53 an hour, and that is before you have made a penny of profit above the wage you set yourself. Charge £45 an hour flat and you are not running a cheap business. You are running it at a loss and paying for the privilege out of your own evenings.
If the maths shape feels familiar, it is. The plumber working out and the electrician working out land in the same place, because the costs that catch one self employed tradesperson catch the next for the same reasons.
The employed benchmark you have to beat
Here is the sanity check that stops you underpricing.
A qualified heating and gas engineer on the nationally agreed technical grade earns around £21 to £24 an hour employed, under the JIB-PMES National Working Rule Agreement that sets pay across plumbing and mechanical engineering services. On top of that hourly rate the employed engineer gets holiday pay, sick pay, and a pension paid in by the employer, and they clock off with none of the paperwork and none of the risk.
Now run your own number through the maths above. If your rate, after the van and the tax and the unbilled hours come off, leaves you taking home less per hour than the employed engineer with a P60 and a pension, something is wrong. Going out on your own is supposed to come with a premium for the risk, the registration and the paperwork, not a pay cut you never noticed. If your figure does not clear the employed benchmark comfortably, your rate is too low. Put it up.
Hourly, day rate, or priced work
Once you know your number, you still have to decide how to charge it.
Hourly suits small jobs where nobody knows how long it will take. A boiler that keeps locking out and might be the PCB or might be the fan, a radiator that will not heat, a customer who says can you just take a look. Put a minimum first hour or a call out charge on these. The £70 to £130 first hour is not greed, it covers the drive and the slot you cannot now sell to anyone else.
Fixed price suits the repeatable stuff you have done a hundred times. A boiler service, a landlord gas safety record, a smart thermostat fit. You know how long it takes, so you can price it and beat your own clock. Just make sure the fixed price, divided by the time you are genuinely on the job rather than driving to it, still clears your hourly number. A £90 service that eats two hours with the travel is £45 an hour. Do enough of those in a row and you have talked yourself back below your floor without noticing.
Priced or quoted install work is where the money is once you are quick and accurate at quoting. Combi swaps, system upgrades, full heating installs. You quote a price, you beat your own estimate by being good and organised, and the upside is yours instead of the customer's. The bottleneck is almost never the pipework or the wiring. It is how fast you can get an accurate quote out the door while the customer is still keen.
Charging the right rate only works if you actually collect it
You can do all of this maths perfectly and still end up underpaid, because the rate on the quote is not the rate that hits your bank.
Gas work is death by small invoices. The £90 service that feels too small to stop and raise, so it waits, and a fortnight later you cannot remember who you did or what you charged. The landlord cert billed to a letting agent who takes six weeks and three chases to pay. The boiler install where the final payment sits unbilled because you were straight onto the next breakdown. Every one of those drags your real hourly rate below the careful number you just worked out. The hours you do not invoice, and the invoices you do not chase, are exactly the leak that turns a £53 an hour business into a £40 an hour one without you ever changing your price.
That is the part Vanly is built for. You speak the job into your phone from the van and the invoice goes out the same day, not the following Sunday, the way voice notes turn into invoices without you opening a laptop. The slow paying agents get chased in your own voice on a schedule instead of whenever you remember and feel brave enough. It is the same office manager described in the AI for gas engineers rundown, pointed at the two jobs that quietly decide your year: getting every invoice out, and collecting every one. You set the rate. Vanly makes sure you actually get paid it. A rate you calculated and then failed to invoice is just a number on a quote.
FAQ
What is the average gas engineer hourly rate in the UK in 2026?
The national average for standard domestic work in 2026 is roughly £50 to £90 per hour, lower at £45 to £70 across the North and Wales, and £70 to £120 in London and the South East. Emergency and out of hours work runs £90 to £150 per hour, and a call out or minimum first hour typically sits at £70 to £130. Those are the prices customers pay. They are a market reference, not the rate you should set your own pricing by, because they take no account of your costs or your unbilled hours.
What should a newly self employed gas engineer charge per hour?
Work it backwards rather than copying the going rate. Take your target take home, gross it up for tax and National Insurance, add your annual overheads including Gas Safe registration and analyser calibration, then divide by the hours you will realistically bill, which for a solo domestic engineer is closer to 1,200 than 2,080. For most that lands the floor around £53 an hour, not the £45 a mate might quote. Charging below your calculated floor means working at a loss.
How much does Gas Safe registration and ACS cost, and does it change my rate?
Gas Safe registration runs a few hundred pounds a year, and your ACS reassessment comes round every five years as a block cost of several hundred more. Neither is optional, because without them you cannot legally do gas work at all. Both belong in your overheads before you set your rate, which is exactly why a gas engineer's floor sits a little above a general plumber's. It is a fixed cost of being allowed to hold the spanner.
Is a day rate better than an hourly rate for gas work?
It depends on the work. A day rate suits predictable full days, install work and subbing for a contractor, and customers find it easier to understand. An hourly rate with a minimum first hour suits small unknown jobs and fault finding. Fixed prices suit the repeatable jobs like services and certs. Whichever you use, check it still clears your calculated hourly number once you divide by the hours you are genuinely on the job, not the hours you are away from home.
Should I charge a call out fee for a gas breakdown?
Yes, for small and emergency jobs. A call out charge or a minimum first hour of £70 to £130 covers the drive and the booking slot you can no longer sell to anyone else. Customers who balk at it are usually the ones who would have taken an hour of free diagnosis and then booked the cheapest quote anyway. Emergency and out of hours work sits higher again, often £90 to £150 per hour on top of the call out, and that premium is fair. You are the one leaving the house at ten at night to a house with no heat.
Will charging more than the going rate lose me work?
Some, and usually the work you want least. Price shoppers chasing the cheapest cert rarely become good long term customers and often turn into the agents you spend Fridays chasing. Price at a rate that pays you, be quick, tidy and reliable, and you win the landlords and homeowners who pay on time and call you back every winter. A diary full of underpriced services is a slow way to go out of business while looking busy.
The bottom line
The honest answer to how much a gas engineer should charge per hour in the UK is that there is no single number, and the cost guides ranking for it are answering the customer's question, not yours. Your number comes from your target take home, your real overheads including the registration and kit that only gas work carries, and the hours you will actually bill across a lumpy year. Work it out once, properly, and stop guessing.
Then make sure you collect every hour of it. The rate is only half the job. Getting the invoice out the day you finish, and chasing the agents who drag, is the other half, and it is the half that quietly decides what you really earned this year. Try Vanly free for 14 days. No card needed to start.
