Receiving a job offer is one of the most significant moments in the employment journey — for candidates and employers alike. Yet the steps between that initial offer and a signed employment contract are often misunderstood. What are your legal obligations at each stage? When must a written contract be provided? And what happens if either party changes their mind?
This guide explains the UK hiring process in full, from the moment a job offer is made to the point at which both parties have signed. It covers the rights and obligations that apply throughout, along with practical advice on what to do when things do not go to plan.
Summary in brief
- Verbal offers are legally binding: Once accepted, a verbal job offer creates a contract of employment under UK law, even without a written document.
- Written statement required by day one: Employers must provide a written statement of employment particulars from the first day of work, as required by the Employment Rights Act 1996.
- You can negotiate before signing: Terms offered verbally or in writing are not necessarily final — candidates can raise queries or negotiate before signing.
- Withdrawing carries legal risk: Backing out after accepting an offer — even verbally — may amount to breach of contract, though claims are rarely pursued if withdrawal happens promptly.
- Digital signing is fully valid: Electronic signatures are legally recognised in the UK and carry the same weight as a handwritten signature.
What Does a Job Offer Mean in the UK?
A job offer is a formal proposal from an employer to a candidate, confirming that they wish to appoint them to a specific role on stated terms. It typically sets out:
- Job title and a description of responsibilities
- Salary and any benefits package
- Proposed start date
- Location and expected working hours
Offers can be made verbally — in an interview, by phone, or by video call — or in writing, most commonly by email or letter. In legal terms, the format matters less than the clarity of the terms communicated and whether they have been accepted.
Verbal vs. Written Job Offers
Most employers follow up any verbal offer with a written one, often called an offer letter or, in some cases, a cover letter confirming the role details. This document sets out the key terms agreed and may include conditions — such as satisfactory references, a right to work check, or a DBS (Disclosure and Barring Service) clearance.
A written offer letter provides a clear record of what was agreed and significantly reduces the risk of misunderstanding for both sides. While it is not a statutory requirement in its own right, it is strongly recommended practice and forms part of a well-managed recruitment process.
Is a Verbal Job Offer Legally Binding?
Yes. Under UK contract law, a verbal job offer that has been clearly accepted by the candidate constitutes a legally binding employment contract — even if no document has been signed. According to Acas, an employment contract can be formed verbally, in writing, or even through conduct — and the absence of a written document does not invalidate it. Employers are nonetheless legally required to provide a written statement of employment particulars on or before the employee's first day of work.
This means that if an employer withdraws a verbal offer after acceptance, the candidate may have grounds for a breach of contract claim. In practice, such claims are harder to pursue without written evidence — which is a further reason for both parties to request or provide written confirmation promptly.
Steps from Job Offer to Signed Contract
Understanding the typical sequence of events gives both candidates and employers a clear framework for managing the process with confidence.
Step 1 — Responding to the Offer
On receiving an offer, the candidate has three options:
- Accept the offer in full (verbally or in writing)
- Negotiate specific terms before accepting (salary, start date, notice period)
- Decline the offer, at any point before acceptance
There is no fixed legal deadline for responding, but most employers expect a decision within a few working days. If you need more time, it is entirely reasonable to ask — and reputable employers will generally accommodate a short extension.
Step 2 — Pre-Employment Checks
Following acceptance, the employer will typically complete pre-employment checks before issuing the formal written contract. Many offers are made conditionally, subject to these checks returning satisfactory results. It is important to clarify which conditions apply and what "satisfactory" means in each case before formally accepting.
Pre-Employment Checks to Expect
References
Requests sent to previous employers to verify employment history and conduct
Right to work
Legal requirement for all UK employers; must be verified before the start date
DBS check
Required for roles working with children or vulnerable adults, including NHS positions
Qualifications
Verification of professional licences or academic credentials where the role requires them
Occupational health
May apply for roles with specific physical or medical requirements
Step 3 — Receiving and Reviewing the Written Statement
Under the Employment Rights Act 1996, as updated by the Good Work Plan reforms introduced on 6 April 2020, employers must provide a written statement of employment particulars from the first day of employment. This is a legal obligation, not optional.
Good to know
The written statement and the employment contract are often the same document. In some organisations, they are provided separately. If you receive two documents, both must be reviewed carefully before signing either.

Step 4 — Signing the Employment Contract
Once the contract has been reviewed and any queries resolved, it is signed by both employer and employee. Increasingly, this is done electronically — which is both legally valid and far more efficient, particularly for remote or multi-site employers.
Electronic signatures are recognised under the Electronic Communications Act 2000 and are consistent with the UK's retained eIDAS framework. A digitally signed employment contract carries the same legal standing as a wet ink signature, provided the identity of the signatories can be verified.
What Must a UK Employment Contract Include?
The written statement must, at minimum, cover the following from day one of employment:
Mandatory element | Details required |
|---|---|
Parties, start date & continuity | Full legal names, addresses, start date, and date continuous employment began |
Job title | Or a brief description of duties |
Rate of pay | Amount and frequency of payment |
Working hours | Days of the week and whether hours are variable |
Place of work | Address(es) where work is to be carried out |
Holiday entitlement | Total days per year, including bank holidays |
Probationary period & notice | Duration and conditions of probation; minimum notice required from both sides |
Pension arrangements | Whether a workplace pension scheme applies |
Beyond the statutory minimum, most contracts also address confidentiality obligations, intellectual property assignment, sick pay, and any restrictive covenants that apply after employment ends.

How Long Should You Wait for Your Contract?
There is no statutory deadline for sending a contract before the start date. The legal obligation is simply that the written statement must be provided by day one of employment. In practice, most employers send contracts one to two weeks before the agreed start date to allow sufficient time for review.
Important
If you begin work and have not received a written statement, your employer is still legally required to provide one from your first day. Raise the matter directly with HR or your line manager. If the issue remains unresolved, Acas offers free, impartial guidance and can help you understand your options.
Significant delays in receiving a contract — particularly where the employer cannot or will not explain the reason — may indicate administrative problems or, in some cases, that the offer terms are being revised. If you are concerned, seek independent employment advice before starting the role.
Can You Change Your Mind After Accepting an Offer?
This is one of the most frequently asked questions during the UK hiring process, and the answer depends on timing and circumstances.
Withdrawing Before Signing
If you have accepted an offer verbally but have not yet signed a written contract, you may withdraw. However, because a verbal acceptance creates a binding agreement, the employer could in principle pursue a breach of contract claim — particularly if they have incurred costs as a result, such as declining other candidates or withdrawing a vacancy.
In practice, most employers will not pursue legal action if a candidate withdraws promptly and professionally. The earlier you inform them, the less disruption is caused and the lower the likelihood of any formal dispute.
Withdrawing After Signing
Once both parties have signed the contract, it is legally binding. If you decide not to start the role, the notice obligations set out in the contract apply from the point of signing. Where the contract specifies a notice period, that figure governs. Where it does not, a reasonable period is implied.
The statutory minimum notice applies once employment has begun and service has accrued: one week for between one month and two years' service, then one additional week per complete year of service up to a maximum of 12 weeks. At the pre-start stage, only contractual or reasonable notice applies.
In some circumstances — particularly where the employer has demonstrably suffered losses as a result of your withdrawal — they may seek to recover damages. Legal advice is recommended before withdrawing from a signed contract.
Common Issues During the Hiring Process
Contract Terms That Differ from the Job Offer
It is not uncommon for the written contract to contain terms that were not discussed at the offer stage — or that differ from what was agreed verbally. Common discrepancies include:
- A salary figure that differs from the offer letter
- Additional restrictive covenants not mentioned during the process
- Longer notice periods than those initially indicated
- Variation clauses giving the employer broad discretion to change terms
Attention
Do not sign a contract that contains terms you have not agreed to, or that you do not fully understand. Request clarification in writing. If the discrepancy is significant, seek advice from Acas or an employment solicitor before proceeding.
You have the right to negotiate contract terms before signing. Most employers expect some degree of discussion, particularly at senior level or where the candidate has raised legitimate concerns.
Starting Work Without a Signed Contract
Employment occasionally begins before the contract paperwork has been finalised. In this situation, an implied contract of employment exists from the moment you start work. The terms implied will typically reflect what was agreed in the offer letter or verbally during the hiring process.
Your right to a written statement still applies from day one, regardless of whether a formal contract has been exchanged. Starting work does not waive this right. For employers, our guide on the key steps to hiring your first employee covers how to ensure documentation is in place from the outset.

Conclusion
The process from job offer to signed employment contract involves more legal substance than many people realise. A verbal offer is binding, a written statement is a legal requirement from day one, and both parties carry obligations throughout. Understanding each step — and knowing what to do if something goes wrong — puts both employers and candidates in a much stronger position.
Taking the time to review any contract carefully before signing, and to raise any discrepancies early, is the most effective way to begin an employment relationship on solid ground.

Frequently Asked Questions
Are verbal job offers legally binding in the UK?
Yes. A verbal job offer that has been clearly accepted creates a legally binding employment contract under UK law. Without written evidence, however, the terms can be difficult to enforce — which is why both parties should always request or provide written confirmation promptly.
How long does a UK employer have to provide an employment contract?
Employers must provide a written statement of employment particulars from the first day of employment, as required by the Employment Rights Act 1996. Most employers send the contract before the start date to allow adequate time for review, but the legal obligation is day one.
What should I do if my employment contract differs from my job offer?
Raise the discrepancy in writing before signing. If the issue is material — such as a different salary or unexpected restrictive covenants — seek advice from Acas (free and impartial) or an employment solicitor before proceeding. Never sign under pressure without resolving the issue.
Can I withdraw after accepting a job offer but before signing a contract?
Yes, but a verbal acceptance creates a binding agreement. Withdrawal is rarely pursued legally if done promptly — always notify the employer as soon as possible and in writing to minimise any risk.
What happens if I start work without a signed contract?
An implied contract of employment exists from the moment work begins. Your employer is still legally required to provide a written statement of particulars by day one. If they do not, you can raise the matter with them directly or contact Acas for guidance.
What are my rights if an employer withdraws a job offer after I have accepted it?
If the offer had been accepted, the employer may be in breach of contract. You may be able to claim damages, particularly if you resigned from a previous role or declined other offers in reliance on the offer. Seek advice from Acas or an employment solicitor to understand your position.
