What to do before starting a new job

The gap between accepting a job offer and walking through the door is the most underused period in any career move. Most people spend it finishing their old role, counting down the days and arriving on a Monday with a vague sense that they should have prepared more.

The ones who use the time well start faster, settle quicker and make a stronger first impression without working any harder on day one.

In this blog, we explain what to do before starting a new job in four areas: the admin to close off, the conversations worth having, the preparation that pays off and the mistakes that make a first week harder than it needs to be.

What should you do before starting a new job?

Before starting a new job, confirm the contract and start date in writing, complete any pre-employment checks promptly, hand over properly in your current role, confirm first-day logistics with your new employer, and spend a few hours on light preparation such as reviewing the job description, learning who you will work with and setting up the practical side of your week. 

The aim is to arrive with the admin done and your attention free for the job itself. None of this needs to take long. Most of it fits into a single afternoon, spread across the weeks of your notice period.

Finish the admin before your first day

Paperwork left unfinished has a habit of surfacing in week one, when you would rather be meeting people. Close it off early.

Check the contract matches the offer

Read the full contract when it arrives and compare it line by line with the offer letter. Salary, job title, start date, holiday, notice period, working pattern and any bonus or probation terms should all match what was agreed. Most differences are typing errors, and they are far easier to fix before you sign than after.

Return pre-employment documents promptly

Right-to-work documents, references, qualifications and any role-specific checks tend to arrive in a cluster shortly after acceptance. Deal with each one the day it arrives. Delays on your side slow down your own start date, and a new employer notices how quickly you respond.

Sort the practical details

Confirm your bank details, pension choices, emergency contact and anything else your new employer's onboarding paperwork asks for. If you are moving from contracting to permanent work or changing tax arrangements, check you have your P45 or equivalent from your current employer ready to pass on.

Leave your current role well

How you leave your last job follows you into the next one. Industries are smaller than they look, and the people you work with now will be references, contacts and sometimes colleagues again.

Hand over properly

Write a clear handover document covering live projects, deadlines, contacts and anything only you know. Walk whoever is picking up your work through it in person. The people who leave the best impression are the ones whose team can still find everything three months later.

Hold your standards through your notice period

Switching off mentally the moment you resign is tempting and widely noticed. Deliver your work, turn up on time and support your team through the transition. A good reference is earned in the final weeks as much as in the preceding years.

Be ready for a counter-offer

If you are good at your job, your current employer may try to keep you. Decide in advance how you will respond. A counter-offer rarely fixes the reasons you started looking, and accepting one after saying yes elsewhere damages your reputation with the employer you turned down.

Stay in touch with your new employer

Silence between acceptance and start date makes hiring managers nervous, and it leaves you guessing about your first day. A few short messages solve both.

Confirm the first-day logistics

A week before you start, send a brief email to your manager or HR contact confirming your start time, where to go, who to ask for and what to bring. Ask whether you need to set anything up in advance, such as accounts or equipment. Clear answers remove the small uncertainties that make a first morning stressful.

Ask what your first week will look like

A short question about how the first week is planned tells you what to expect and signals that you are engaged. If your manager offers to send anything to read in advance, take it. If they do not, do not push for homework. Most employers want you to arrive rested rather than briefed.

Reply to any onboarding emails the day they arrive

Introductions from new colleagues, invitations to systems and welcome messages all deserve a quick reply. It costs a minute and it means you arrive as someone the team has already heard from.

Prepare without overdoing it

A little preparation makes your first week easier. A lot of it is wasted, because you will learn more in your first three days than in three weeks of reading from outside.

Re-read the job description and your interview notes

Go back to the job description and anything you noted during the interviews about priorities, challenges and what your manager said they needed. Those are the things you will be measured on. Having them fresh in mind when you sit down for your first one-to-one puts you a step ahead.

Learn who you will be working with

Look up your manager, your immediate team and the people in the roles you will work closely with. Knowing names, job titles and roughly what each person does means your first introductions are conversations rather than memory tests.

Refresh any skills you know you will use early

If the role leans on a tool, language or system you have not touched for a while, spend an hour or two getting back up to speed. The point is not to arrive as an expert but to avoid being slowed down in week one by something you could have refreshed in an evening.

Set up the practical side of your week

Test the commute or your home working setup. Sort childcare, travel and anything else that would otherwise compete for your attention in the first few days. If you are working hybrid, find out which days are expected in the office before you start, not on the Monday.

Take a proper break if you can

If there is a gap between roles, use at least part of it to rest. Starting a new job while still recovering from the last one rarely produces a strong first month. Candidates who arrive with some energy in reserve settle faster and handle the inevitable early frustrations better.

Mistakes to avoid before starting a new job

A few habits turn a manageable transition into a stressful one. All of them are avoidable.

Going quiet

We regularly hear from hiring managers who have not heard from a new hire since the contract was signed and are quietly wondering whether they will turn up. A single check-in a week before your start date removes that doubt entirely.

Promising a start date you cannot meet

If your notice period is longer than expected or your current employer asks you to work extra time on a project, say so immediately rather than hoping it resolves itself. Employers would far rather adjust a date early than discover a problem the week before.

Trying to learn the whole job in advance

Reading every document on the company website and memorising the org chart does not make you better at the job. It makes you tired before you start. Light preparation, then learning on the inside, is the approach that works.

The weeks before a new job are a window, not a waiting room. Close off the admin, leave your current role well, keep in touch with your new employer and prepare lightly for the things you will be judged on first. Do that and you arrive with your attention on the work rather than the logistics.

The candidates who settle fastest into new roles are rarely the ones who studied hardest beforehand. They are the ones who handled the practical details early, stayed visible to their new employer and turned up rested and ready to learn.
