How Much Do Fire And Security Subcontractors Earn In The UK?
If you’re an experienced fire and security engineer considering subcontract work, one of the first questions you’ll probably ask is how much you could earn.
It’s a fair question. Subcontracting can offer significantly higher daily earnings than permanent employment, but the headline rate doesn’t tell the whole story. The amount you earn depends on your experience, the systems you work with, where you’re prepared to travel and, perhaps most importantly, how consistently you’re working.
A subcontractor charging £300 a day isn’t necessarily earning more over a year than someone charging £250. Equally, a higher day rate doesn’t automatically mean you’ll be better off than you were in permanent employment.
So, what are realistic fire and security subcontractor rates in the UK, and what could those rates mean for your annual earnings?
What Are Typical Fire And Security Subcontractor Day Rates In The UK?
As a broad guide, fire and electronic security subcontractors working in the UK may see day rates ranging from approximately £180 to £350, with some specialist assignments commanding more.
Rates vary considerably depending on the role, the technical requirements, the location and the commercial arrangements.
The following figures provide an indication of potential day rates rather than a fixed industry pay scale.
These figures are broad planning estimates based on advertised contract rates and market examples in 2026. They are not guaranteed rates or a comprehensive industry survey.
A straightforward installation contract may offer less per day than a specialist commissioning assignment. However, if the installation work provides several months of consistent employment, it could ultimately prove more financially rewarding.
That distinction matters when deciding which opportunities to accept.
How Much Can A Fire And Security Subcontractor Earn In A Year?
Annual earnings depend on two things: your agreed rate and the number of days you actually work.
For example, an engineer earning £250 per day and working 220 billable days in a year would generate £55,000 in gross revenue.
Here’s how different day rates and working patterns compare:
These calculations show gross revenue before business expenses, taxes and any other deductions. They exclude VAT and assume the full daily rate is billable.
The difference between working 180 days and 220 days is considerable.
For an engineer charging £300 per day, those additional 40 working days represent another £12,000 in annual turnover without any increase in their rate.
This is why experienced subcontractors often place considerable importance on continuity of work rather than simply chasing the highest rate available.
What Affects Fire And Security Subcontractor Pay?
Experience And Technical Ability
An engineer who can independently install, service, diagnose faults and commission complex systems will generally have more opportunities to negotiate higher rates.
Clients are paying for someone who can arrive on site, understand the requirements and complete the work with minimal supervision.
The ability to resolve unexpected technical problems can be particularly valuable. If a contractor needs someone to investigate an intermittent fault on a complex fire alarm system, they’re likely to prioritise proven expertise over someone who simply offers a lower rate.
Manufacturer And System Knowledge
Experience with specific manufacturers can influence the subcontract work available to you.
For example, an engineer familiar with advanced access control platforms, enterprise CCTV systems or complex addressable fire alarm systems may qualify for assignments that aren’t suitable for a general installation engineer.
Experience with systems such as Gallagher, LenelS2, Genetec, C-CURE, Advanced or Gent can be commercially useful when clients require particular knowledge.
However, simply listing manufacturer names isn’t enough. Clients need confidence that you have the practical ability to work competently on the systems involved.
Relevant training, certifications and demonstrable project experience can strengthen your position.
Location And Willingness To Travel
Geography can affect subcontract rates, particularly where demand for experienced engineers exceeds local availability.
London and the South East may offer higher headline rates than some other regions, but travelling into London brings additional considerations.
Fuel, parking, congestion charges, accommodation and unpaid travelling time can quickly reduce the benefit of an apparently attractive rate.
A £300-per-day contract requiring a lengthy daily commute might ultimately be less appealing than £260 per day on a project close to home.
For engineers prepared to work away, it’s worth establishing whether accommodation, mileage, subsistence or travel time are paid separately.
Project Duration And Urgency
A client needing an engineer immediately for a short, technically challenging assignment may be prepared to offer a higher rate.
Longer contracts can sometimes offer slightly less per day but provide greater certainty of income.
Neither arrangement is automatically better.
A three-month contract at a sensible rate could be worth considerably more than a series of well-paid individual days with long gaps between them.
Why Your Day Rate Isn't Your Take-Home Pay
One of the biggest mistakes when comparing subcontracting with permanent employment is treating the entire day rate as personal income.
As a subcontractor, you’re operating a business, whether that’s as a sole trader or through a limited company.
Depending on your arrangements, you may need to cover:
- Vehicle purchase, leasing, maintenance and insurance.
- Fuel, parking and business travel.
- Public liability and other relevant insurance.
- Tools, test equipment and calibration.
- Training, certifications and site access requirements.
- Accountancy and business administration.
- Unpaid holidays, sickness and gaps between contracts.
- Pension contributions and other benefits previously provided by an employer.
You’ll also need to account for the appropriate taxes and National Insurance, depending on your circumstances and business structure.
Consider two engineers.
Engineer A charges £300 per day and works 180 days during the year, generating £54,000.
Engineer B charges £260 per day and works 220 days, generating £57,200.
Despite charging £40 less per day, Engineer B generates an additional £3,200 in annual revenue.
If Engineer B also works closer to home and incurs lower expenses, the difference could be greater.
These examples illustrate why the best rate isn’t always the highest rate.
How Important Is Regular Contract Work To Your Earnings?
For many successful subcontractors, maintaining a regular flow of work is the difference between an occasional good month and a financially rewarding year.
A two-week gap between projects can quickly absorb the benefit of a higher day rate.
An engineer charging £300 per day but losing 20 potential working days between contracts misses out on £6,000 in potential revenue.
This is why building reliable relationships with contractors, specialist recruitment agencies and project managers is so important.
Engineers who communicate their availability, turn up when expected, complete their documentation and deliver consistently good work are often easier to place on future assignments.
At Complete Security Recruitment, our subcontract team works with fire and electronic security businesses requiring additional engineering support for installations, service work, commissioning and specialist projects.
We understand that a subcontractor’s priority isn’t necessarily securing one highly paid assignment. It’s finding worthwhile projects and reducing unnecessary gaps between them.

Can Specialist Fire And Security Subcontractors Earn More?
Specialist skills can create opportunities to command higher day rates, particularly when there are relatively few engineers available with the required experience.
This could include complex fire alarm commissioning, enterprise access control integration, advanced CCTV systems or work on high-security sites.
However, specialist projects may also be less frequent or require additional travel.
An engineer with highly specialised knowledge might command a premium rate for a particular assignment, but that doesn’t guarantee continuous work throughout the year.
There’s a balance to consider.
Some subcontractors build successful businesses by concentrating on a particular manufacturer or type of system. Others maintain a broader skill set, enabling them to move between fire alarm, CCTV, access control and intruder alarm projects as demand changes.
Neither approach is necessarily superior. The right option depends on your skills, location, contacts and the kind of work you want to undertake.
Should You Choose Day Rates Or Fixed-Price Work?
Not all subcontract assignments are paid on a straightforward daily rate.
Some projects involve an agreed fixed price for completing a defined scope of work. Others may be paid hourly, per visit or on a schedule of rates.
Fixed-price work can be attractive when you’re experienced, efficient and confident in the project requirements.
However, it’s important to understand exactly what’s included.
If additional work, unexpected site conditions or delays affect the project, you need to know how variations will be handled.
With a daily rate, you should establish the expected hours, overtime arrangements, travelling requirements and what happens if the project is delayed or cancelled.
Whichever payment structure you accept, clarity at the beginning can prevent disputes later.
Is Fire And Security Subcontracting Better Paid Than Permanent Employment?
Subcontracting can provide greater earning potential, but it’s not a direct comparison with an employed salary.
Permanent fire and security engineers may receive a company vehicle, paid holidays, pension contributions, training, sick pay arrangements and other benefits.
A subcontractor usually needs to make their own financial provision for many of these costs.
Permanent employment also generally offers more predictable income.
Subcontracting, by comparison, may offer more flexibility, variety and opportunities to increase earnings when demand is strong.
For someone moving from employment into subcontracting, it makes sense to calculate the annual revenue needed to replace their entire employment package, not just their basic salary.
It’s also worth considering whether you have sufficient savings to manage quieter periods.
For businesses looking at the other side of the arrangement, our guide to When Should A Fire And Security Company Use Subcontractors Instead Of Recruiting Permanently? explains the commercial considerations.
How Can Fire And Security Subcontractors Improve Their Earnings?
Increasing your day rate is one option, but there are other ways to improve what you earn throughout the year.
Reducing gaps between assignments can make a substantial difference. So can maintaining your qualifications, improving your technical knowledge and being prepared to consider suitable projects outside your usual area.
It’s also worth building a reputation for reliability.
Companies value subcontractors who arrive prepared, work safely, communicate clearly and complete the necessary documentation without repeated chasing.
Those qualities might not appear on a rate sheet, but they can influence whether you’re invited back for the next project.
Just as importantly, know your costs.
Understanding what you need to earn each month, how much it costs you to work and the minimum rate that makes an assignment worthwhile will put you in a stronger position when evaluating opportunities.

Frequently Asked Questions
What Is The Average Fire And Security Subcontractor Day Rate In The UK?
There isn’t a single reliable average covering every type of fire and security subcontract work. As a broad 2026 guide, advertised rates and indicative market figures suggest approximately £180–£350 per day across different disciplines, with specialist work sometimes exceeding this range.
Can A Fire And Security Subcontractor Earn £60,000 A Year?
Yes. A subcontractor charging £300 per day across 200 billable working days would generate £60,000 in annual gross revenue. However, that isn’t the same as taking home £60,000 after expenses and tax.
Do Fire Alarm Subcontractors Earn More Than CCTV Engineers?
Not necessarily. Earnings depend more on the work involved, technical expertise, project requirements and location than on the system category alone. Experienced engineers in either discipline can command attractive rates.
Do Fire And Security Subcontractors Get Paid For Travelling?
This depends on the contract. Some clients pay mileage, accommodation, travel time or other expenses separately, while others expect these costs to be included in the agreed rate. Always clarify the arrangement before accepting an assignment.
Is There Enough Work To Become A Full-Time Fire And Security Subcontractor?
There are opportunities across installation, maintenance, commissioning and specialist electronic security projects, but availability varies by location, experience and client demand. Building relationships with reliable sources of work and keeping your availability updated can help you maintain continuity.
