What is the difference between fixed-term and temporary employment?

A temporary offer letter is used for short-term work where the employer expects the role to last for a limited period, but the exact end date may vary.

What is a zero-hours offer letter?

A zero-hours offer letter is used where there is no guaranteed minimum number of working hours and work is offered as needed.

Can I create an offer letter for a casual worker?

Yes. A casual worker offer letter should explain that work is offered on an irregular basis and should set out pay, holiday entitlement, and any expectations for accepting shifts.

Do apprentices need a different offer letter in the UK?

Yes. Apprenticeship offer letters should include the job role, training arrangements, pay, working hours, apprenticeship duration, and any relevant apprenticeship agreement details.

What should an internship offer letter say?

An internship offer letter should state whether the intern is an employee, worker, volunteer, or student placement, as this affects pay, rights, and responsibilities.

Should I use an employment offer letter for a contractor?

Usually, no. Contractors are generally engaged under a contractor agreement or consultancy agreement, not a standard employment offer letter.

Is an offer letter legally required in the UK?

UK employees and workers are normally entitled to a written statement of employment particulars. An offer letter can help set out key terms but may not replace all legal requirements.

What information should a UK job offer letter contain?

A UK offer letter should usually include the role, start date, employment type, salary or pay, working hours, location, reporting line, conditions, and any probation period.

Can an offer letter be conditional?

Yes. Common conditions include satisfactory references, right to work checks, background checks, qualifications, medical checks, or signing an employment contract.

Why does employment type matter in a job offer letter?

Employment type affects pay, working hours, holiday entitlement, notice periods, job security, benefits, and the wording needed in the offer letter.

How do I choose the right employment type for an offer letter?

Use the employment type that accurately reflects the working arrangement, expected hours, duration, and legal status of the person being hired.

UK Employment Types For Offer Letters

Created: 9 Jun 2026

Understanding UK employment types helps employers create accurate offer letters and set clear expectations for workers. This guide complements our AI Generated British Contract of Employment resources by clarifying key categories before hiring.

Description	Key Offer Letter Terms	Pre-Issue Checks	Drafting Complexity	Common Pitfalls
Permanent employee
Open-ended employment with continuing mutual obligations until terminated by notice, dismissal, resignation or agreement.	Job title, start date, salary, hours, place of work, probation, notice, holiday, benefits, conditions and governing policies.	Confirm right to work, salary approval, role details, reporting line, references, checks and any conditions of offer.	Low	Using vague conditional wording, omitting probation or notice, or promising benefits not yet approved.
Fixed-term employee
Employee engaged for a defined period, project or event, with employment ending on the agreed trigger unless renewed.	End date or event, reason for fixed term, renewal process, early termination, notice, benefits and continuity of service.	Confirm objective reason, budget period, renewal expectations and whether the role may become permanent.	Medium	Failing to include early termination rights or implying automatic renewal without approval.
A fixed-term employee has statutory protection against less favourable treatment because of fixed-term status.	Pro-rated benefits, comparable terms, access to vacancies, training and any justified exclusions.	Compare terms with permanent comparators and document objective justification for any difference.	Medium	Offering lower benefits solely because the contract is fixed-term without objective justification.
Part-time employee
Employee working fewer hours than a comparable full-time worker, usually with employee rights on a pro-rated basis.	Weekly hours, work pattern, pro-rated salary, holiday, benefits, overtime, flexibility and changes to working days.	Confirm actual working pattern, pay calculation, holiday pro-rating and comparable full-time benefits.	Medium	Stating annual full-time salary without pro-rating or giving fewer benefits without justification.
Part-time workers must not be treated less favourably than comparable full-time workers unless justified.	Equal access to pay rates, training, pension, leave, promotion and benefits, usually pro-rated where appropriate.	Check proportional treatment and record any objective justification for different terms.	Medium	Using fewer hours as a reason to deny training, pension or promotion opportunities.
Temporary employee
Employee hired for short-term cover, seasonal demand or a limited assignment, often with an expected end point.	Expected duration, assignment purpose, notice, pay, hours, holiday, extension rights and conditions for early termination.	Confirm whether engagement is direct employment, agency work or casual work and who pays wages and holiday.	Medium	Labelling the role temporary but drafting an open-ended offer with no end mechanism.
A temporary role may overlap with agency worker rules if supplied by an employment business to a hirer.	Identify employer, hirer, assignment, pay arrangements, holiday pay, supervision and any agency-specific documentation.	Check whether the worker is supplied through an agency and whether equal treatment rights may apply after 12 weeks.	High	Issuing a direct employee offer where the business is only the hirer, not the employer.
Casual worker
Ad hoc work offered as needed, usually without an obligation to provide or accept future work.	No guarantee of work, right to refuse shifts, hourly pay, holiday pay, cancellation, status and assignment-by-assignment terms.	Confirm intended status, shift allocation process, holiday pay method and whether regular work creates continuity.	High	Describing the role as casual while requiring ongoing availability or acceptance of every shift.
Casual workers may still have worker rights, including paid holiday and minimum wage protection.	Worker status, hourly rate, holiday entitlement, payment timing, deductions, rest breaks and no employment guarantee.	Confirm pay meets minimum wage and holiday entitlement is calculated using current holiday pay rules.	High	Assuming casual status removes holiday pay, minimum wage or written particulars obligations.
Zero-hours worker
Worker or employee with no guaranteed minimum hours, offered work when available.	No guaranteed hours, shift offer process, right to decline, hourly pay, holiday, notice for shifts and status.	Confirm whether the person will be a worker or employee and whether business needs truly require no guaranteed hours.	High	Including guaranteed hours, mandatory availability or inconsistent scheduling obligations that undermine zero-hours wording.
Zero-hours contracts cannot generally stop the worker working for another employer.	Avoid exclusivity restrictions and sanctions for taking other work, unless a lawful exception clearly applies.	Review restrictive covenants, availability clauses and conflict wording for prohibited exclusivity effects.	High	Adding a blanket ban on other jobs to a zero-hours offer letter.
Apprentice
Employee undertaking paid work and structured training under an approved apprenticeship arrangement.	Apprenticeship standard, training provider, duration, off-the-job training, pay rate, working hours and supervision.	Confirm eligibility, funding, training plan, minimum wage rate, apprenticeship agreement and provider documents.	High	Using an ordinary employee offer without apprenticeship training obligations or agreement details.
Certain apprenticeships require a compliant apprenticeship agreement or approved English apprenticeship agreement.	Skill, trade or occupation, apprenticeship framework or standard, training period and employment terms.	Ensure the offer aligns with the apprenticeship agreement, training plan and statutory apprenticeship requirements.	High	Failing to distinguish an apprenticeship agreement from a traditional contract of apprenticeship.
Apprentices have specific minimum wage rules depending on age and apprenticeship year.	Hourly rate, annual salary equivalent, training hours, paid study time and rate increases when eligibility changes.	Check age, apprenticeship year, working time, training time and current National Minimum Wage rate.	High	Forgetting to increase pay when the apprentice becomes entitled to a higher minimum wage rate.
Intern
Short-term work experience or trainee role legal status depends on the reality of work and obligations.	Status, duration, duties, supervision, pay or expenses, hours, learning aims and whether work is required.	Assess whether the intern is a worker entitled to minimum wage and paid holiday.	High	Calling the role unpaid work experience while requiring productive work and fixed hours.
Interns who count as workers are generally entitled to National Minimum Wage.	Pay rate, expenses, hours, voluntary status, learning objectives and whether there is an obligation to perform work.	Check whether any exemption applies, such as genuine volunteering, student placement or work shadowing.	High	Relying on the label intern to avoid minimum wage where the person is doing required work.
Permanent employee
Permanent employees must receive key written employment particulars from day one of employment.	Main terms should align with written particulars covering pay, hours, place, holiday, notice and job title.	Ensure the offer letter and employment contract do not conflict on core terms.	Low	Issuing an offer with salary, hours or location that differs from the contract particulars.
Part-time employee
Part-time employees are entitled to statutory paid holiday calculated according to their working pattern.	Holiday entitlement in days or hours, bank holiday treatment, accrual and pro-rated annual leave.	Use a holiday calculation that fits the agreed days, hours or irregular pattern.	Medium	Giving full-time bank holiday wording that disadvantages staff who do not work Mondays.
Zero-hours worker
Zero-hours workers are generally entitled to statutory holiday based on work done.	Holiday accrual, holiday pay calculation, request process and whether rolled-up holiday pay is used lawfully.	Check current holiday pay rules for irregular hours or part-year workers before drafting pay wording.	High	Stating that holiday is included in the hourly rate without lawful rolled-up holiday pay wording.
Temporary employee
Seasonal temporary employment supports peak trading periods, events or holiday cover.	Season dates, expected end date, shift pattern, overtime, holiday, uniform, training and early finish rights.	Confirm peak period dates, staffing budget, minimum age requirements and right to work evidence.	Medium	Omitting what happens if the season ends early or demand falls unexpectedly.
Intern
A student placement may be exempt from minimum wage if it is required by a UK-based course and lasts under one year.	Placement purpose, course requirement, duration, learning outcomes, supervision, expenses and no employment guarantee.	Verify course requirement, placement length and university or college documentation.	High	Assuming all students can be unpaid regardless of placement structure or duration.
Permanent employee
A permanent offer may be conditional on checks such as references, right to work, qualifications or screening.	Clear conditions, deadline for satisfaction, withdrawal rights and start date dependency.	Decide which checks are mandatory before employment starts and which can follow acceptance.	Low	Making the offer sound unconditional before required screening has been completed.
Fixed-term employee
Fixed-term employment is often used for maternity, parental leave, sickness or secondment cover.	Cover reason, anticipated end date, return-of-employee trigger, notice and possibility of extension.	Confirm whether the end is date-based, event-based or whichever occurs first.	Medium	Stating a fixed end date only when the real trigger is the absent employee returning.
Casual worker
Casual engagement suits event, hospitality or relief staffing where work is intermittent and optional.	Separate shift engagements, acceptance process, cancellation, pay after each assignment and conduct rules.	Confirm rota process, cancellation payment rules and whether repeat work creates a regular pattern.	High	Using permanent employee wording such as normal working hours and continuous employment.
Zero-hours worker
A zero-hours arrangement can still create employee status depending on control, obligations and working reality.	Status label, no guaranteed hours, acceptance rights, control, substitution if applicable and continuity wording.	Assess actual control, personal service and mutual obligations before selecting worker or employee wording.	High	Assuming zero-hours automatically means self-employed or removes employment rights.
Part-time employee
Part-time employment may involve fixed days, compressed hours or other flexible working arrangements.	Working days, start and finish times, flexibility limits, rota notice and process for changing hours.	Confirm operational cover, manager approval and whether the pattern results from a flexible working request.	Medium	Saying hours are flexible without defining who can vary them and on what notice.
Apprentice
Apprenticeship arrangements can carry higher termination risk if training rights are not properly addressed.	Termination rights, misconduct, capability, redundancy, training obligations and effect on apprenticeship completion.	Confirm the contract type and whether a standard employment termination clause is suitable.	High	Assuming an apprentice can be dismissed on the same basis as any probationary employee.

What Employment Type Should A UK Offer Letter State?

A UK offer letter should match the real working arrangement. Permanent, fixed-term, part-time and temporary employees usually need clear employee terms, while casual and zero-hours arrangements need careful wording so the letter does not accidentally promise guaranteed work. Apprentices and interns require extra checks because pay, training structure, supervision and employment status can change the legal risk.

Which Offer Letter Terms Need The Most Care?

Fixed-term offers: state the end date, renewal position and early termination rights, and avoid treating fixed-term staff less favourably without objective justification.
Part-time offers: state hours, work pattern and pro-rated pay and benefits, because part-time workers are protected from less favourable treatment.
Zero-hours and casual offers: avoid exclusivity clauses that restrict other work and avoid wording that guarantees shifts if the business does not intend to do so.
Apprentice offers: confirm the apprenticeship standard, training provider, off-the-job training and pay rules before issue.
Intern offers: check whether the intern is a worker or employee for minimum wage and holiday purposes; calling the role an internship is not decisive.

What Checks Should Be Completed Before Issuing A UK Offer Letter?

Employers should confirm right to work, salary and National Minimum Wage compliance, probation, hours, notice, holiday entitlement and any conditions such as references, qualifications, DBS checks or professional registration. Where the role has a non-standard structure, the offer letter should be adapted rather than reused from a permanent full-time template.
