How to Compare an Energy Job Offer Properly
A high day rate can look better than a salary at first glance. That does not automatically make it the better offer. The real comparison depends on how many days are paid, what the worker must fund, how tax is handled and what happens between assignments.
This is particularly important in oil and gas, offshore construction, commissioning and shutdown work, where two roles with similar headline pay can produce very different annual earnings and levels of security.
The correct comparison is total annual value after costs and risk. Start with the contract, not the headline number.
Understand What the Rate Actually Covers
A salary normally describes gross annual pay. A day rate describes payment for an agreed unit of work, but the contract determines which days qualify. Some assignments pay every day on rotation. Others pay only site days and exclude travel, training, standby, weather delays or quarantine.
Before doing any calculation, establish the basis of payment. Ask whether the quoted rate is gross or net, whether it is paid directly or through an agency or company, and whether deductions will be made before the money reaches you.
| Question | Why it changes the value |
|---|---|
| Which days are paid | Site days, travel days, training, standby and mobilisation may be treated differently. |
| Is the rotation guaranteed | A theoretical annual total is unreliable if trips can be cancelled or shortened. |
| Who pays travel and accommodation | Flights, hotels, transfers, meals and visas can remove a large part of the apparent premium. |
| What is the employment status | Status affects tax responsibilities, employment rights and access to benefits. |
| What happens between assignments | Unpaid gaps and project delays reduce annual earnings. |
Calculate Realistic Paid Days
Do not multiply a day rate by 365 unless the contract genuinely pays every calendar day. Use the rotation and paid-day rules in the contract.
For an equal-time rotation, a rough starting point is half the year. A 14 days on and 14 days off pattern produces about 182 or 183 scheduled working days across a full year. The actual number may differ because of start dates, crew-change arrangements, additional trips, sickness, training and project delays.
The basic calculation is straightforward:
Gross annual contract income = day rate x realistically paid days
For example, a rate of £500 paid for 182 days gives gross contract income of £91,000. That figure is not take-home pay and it is not directly comparable with a £91,000 salary until costs, benefits and tax treatment are considered.
Value the Salaried Benefits
A salary can include value that does not appear in the headline figure. Depending on the employer and jurisdiction, this may include paid leave, employer pension contributions, sick pay, life assurance, medical cover, bonuses, training and redundancy rights.
In the UK, most workers are legally entitled to paid annual leave, and workplace pension arrangements commonly include an employer contribution. Entitlement depends on status and circumstances, so candidates should confirm the contract rather than assume every salaried role provides the same package.
- Employer pension contribution
- Paid holiday and public holiday treatment
- Company sick pay and income protection
- Medical, life and travel insurance
- Bonus, overtime and offshore allowances
- Paid training, certification and professional membership
- Relocation, accommodation or travel support
Identify the Contractor Costs
Contractors may need to replace benefits that an employer would otherwise provide. The exact position depends on the engagement model and country, but common costs include accounting, insurance, pension saving, unpaid leave, professional fees, training and periods without work.
- Agency, umbrella or payroll fees
- Accountancy and company administration
- Professional indemnity, public liability or other insurance
- Personal pension and loss-of-income protection
- Medical, offshore and technical certification renewals
- Travel, accommodation, visas and work permits when not reimbursed
- Unpaid holidays, sickness, mobilisation delays and gaps between contracts
A sensible comparison creates an annual allowance for each relevant cost rather than treating irregular expenses as though they do not exist.
Check Tax and Employment Status
Contract labels do not decide employment status on their own. The working arrangement and local rules matter. A person may also have one status for employment law and another for tax.
UK contractors working through an intermediary may fall within the off-payroll working rules commonly called IR35. HMRC states that these rules are intended to ensure that someone who would have been an employee if engaged directly pays broadly similar Income Tax and National Insurance. The rules are assessed contract by contract.
International work adds further questions. Tax residence, payroll location, social-security contributions and permanent-establishment rules can affect the result. Candidates should obtain qualified advice for their circumstances instead of relying on another worker’s arrangement.
Put a Value on Certainty
A twelve-month contract is not always twelve months of guaranteed income. Check the notice period, termination rights, project funding, mobilisation conditions and whether the client can reduce the rotation.
A contractor may reasonably expect a higher gross return because they accept more risk. The premium needs to cover uncertainty as well as costs. If the day-rate offer only matches the annual value of the salary after optimistic assumptions, it may not be a genuine premium.
Compare the Complete Packages
| Factor | Salaried role | Day-rate role |
|---|---|---|
| Headline pay | Annual gross salary | Rate multiplied by paid days |
| Paid leave | Often included subject to contract and law | Often unpaid or built into the rate |
| Pension | Employer contribution may apply | Usually funded by the contractor |
| Training | May be employer funded | May be a personal cost |
| Downtime | Income may continue | Gaps may be unpaid |
| Travel | May be included or reimbursed | Must be confirmed for every assignment |
| Security | Usually stronger but never absolute | Depends on term, notice and project continuity |
| Tax | Normally deducted through payroll | Depends on status, structure and jurisdiction |
Use a Fair Comparison
A practical annual comparison can be built in five stages.
- Estimate realistic paid days using the written rotation and payment terms.
- Calculate gross annual contract income.
- Subtract contractor-funded costs and a realistic allowance for unpaid time.
- Add the cash value of salary benefits to the salaried offer.
- Compare the resulting values alongside security, lifestyle and career development.
The final decision is not purely financial. A day-rate contract may offer flexibility, international experience or a route into a major project. A salary may provide progression, structured training and greater predictability. Those differences should be considered openly rather than hidden behind one annual number.
Questions to Ask Before Accepting
- What days and activities are paid
- Is the rotation contractual and guaranteed
- Who pays flights, accommodation, transfers, meals, visas and medicals
- What are the notice and early-termination terms
- How are overtime, standby, training and travel days paid
- What deductions, fees or withholding taxes apply
- Which benefits and insurances are included
- What happens if the mobilisation date moves
Make the Decision from the Contract
The highest headline figure is not necessarily the strongest offer. Calculate realistic paid days, include the value of benefits, account for personal costs and understand the risk you are accepting.
If important terms are unclear, ask for them in writing before resigning, travelling or committing money to mobilisation requirements.
