The week you decide to go out on your own as an independent consultant, the work itself barely changes: the wrapper around it does. You still run the same grievance investigation, the same Microsoft 365 migration, the same risk assessment you have run a hundred times. What changes is that nobody is standing behind you. You are a supplier now, and suppliers get asked things employees never get asked. Who insures this. What is your day rate. Can you send your terms. Are you inside or outside IR35. Have you completed our supplier questionnaire.
For an independent consultant, most of that admin can be done in a fortnight. The part that takes longer, and the part people skip, is deciding exactly what you sell and to whom.
What Are You Actually Selling?
“Management consultant” tells a buyer nothing. It is the business equivalent of writing “good with people” on a CV. The consultants who fill a diary in their first year are the ones who can finish this sentence in one breath: I help X sort out Y.
Compare these two. “I’m an HR consultant.” Against: “I handle TUPE transfers and grievance investigations for firms with 20 to 200 staff who have no HR director.” The second one gets remembered and repeated by the accountant who hears it at a networking breakfast. The first one gets forgotten by the time he has finished his coffee.
The same goes across the board. A health and safety consultant who names CDM duties for small building contractors. An IT consultant who does cloud migrations for legal practices. A finance consultant who does board packs and cash flow forecasting for owner managed businesses in the £1m to £10m turnover range. Narrow does not mean fewer clients. It means the right ones can recognise themselves in what you say.
Sole Trader Or Limited Company As An Independent Consultant
As an independent consultant you can trade as a sole trader from day one. Tell HMRC, keep records, file a self assessment return, done. It is cheaper and faster, and for a part time advisory practice that bills a handful of small clients, it can be the right answer for years.
The friction shows up when you start selling to bigger organisations. Procurement teams at councils, NHS trusts and large private firms often have supplier onboarding that assumes a limited company: company number, certificate of incorporation, insurance certificates, sometimes two years of accounts. Some framework agreements will not take a sole trader at all. If your target client is a 3,000 person employer, an independent consultant working through a limited company usually has an easier ride through their systems.
There is also liability. Advice can go wrong. If you sign off a redundancy process that ends at tribunal, or specify a system that loses a client three days of trading, a limited company puts a legal wall between the business and your house. That wall is not absolute, and it is no substitute for insurance, but it matters.
The trade-off is paperwork. Annual accounts, a confirmation statement, corporation tax, PAYE if you pay yourself a salary, and an accountant who will charge you for all of it. Plan on that costing four figures a year rather than three.
The Insurance An Independent Consultant Should Not Skip
Professional indemnity is the one that matters for an independent consultant. It covers claims that your advice or your work caused a financial loss. Clients know this, which is why the insurance clause in their contract usually names a figure, and £1 million and £2 million are the levels you see most often in mid sized corporate terms.
Two details that catch people out. First, most professional indemnity policies are written on a claims made basis, which means the policy that pays out is the one live on the day the claim is made, not the day you did the work. If you wind the practice up and cancel the policy, a claim arriving eighteen months later has nothing behind it. That is what run-off cover is for, and you should budget for a few years of it whenever you stop trading.
Second, get the cover in place before the contract is signed, not after. An independent consultant who signs terms promising £2 million of professional indemnity and then goes shopping for it is in breach from the first day of the engagement.
Beyond that: public liability if you set foot on client sites, which most health and safety and IT people do; employers’ liability the moment you take on anyone, including a part time admin helper; and cyber cover if you hold client data on your own machines, which almost everyone does.
Data Protection: The Bit Consultants Forget
An HR consultant handling disciplinary files holds some of the most sensitive personal data there is. A marketing consultant running a client’s mailing list holds thousands of contacts. A finance consultant has payroll records. All of that puts you in scope of UK data protection law, and most consultancies also have to pay the annual data protection fee.
The Information Commissioner’s Office has a short self assessment that tells you whether you need to register and what tier you fall into. Do it early: check the ICO self assessment and pay the fee if it applies. It is not expensive and clients increasingly ask for your registration number on the supplier form.
As an independent consultant you will also be asked to sign data processing terms. Read the bit about where you store files. If your answer is “a folder on my laptop and a personal Dropbox”, tidy that up before you promise otherwise in writing.
Your Day Rate Is Not Your Old Salary Divided By 220
This is where new consultants lose the most money, and they lose it quietly for two or three years before they notice.
Picture someone leaving a £60,000 HR manager job. Employer pension and national insurance mean that role actually cost the employer meaningfully more than the salary. Then take the year apart. There are roughly 250 working days. Take off holiday, bank holidays, a few sick days, and you are near 220. Now take off the days you spend selling, invoicing, writing proposals that go nowhere, doing your own accounts and sitting on calls that never become work. A busy independent consultant in a good year bills 130 to 160 days. In year one, 100 is more realistic.
Divide the true cost of employment by 130 rather than 220 and the number jumps. Then add your own overheads: insurance, accountant, software, professional body membership, training, travel you no longer get reimbursed for. Then add a margin, because a business that only breaks even is a job with extra paperwork.
Whatever number that gives you, do not discount it to win the first job. The client who negotiates you down £150 on day one negotiates from that number forever, and they tell their contacts what they paid.
IR35 And The Independent Consultant
If you work through your own limited company for a medium or large private sector client, or any public sector body, that client decides whether the engagement is inside or outside the off-payroll rules and must give you a status determination statement. Small clients are treated differently, and the responsibility for getting it right stays with your own company. The rules and the current definitions are set out on gov.uk’s off-payroll working guidance.
In practice, three things push an engagement towards inside: being told when and where to work, having no right to send a substitute, and looking like part of the client’s team rather than a supplier delivering a defined piece of work. A genuine independent consultant delivering a scoped project, on their own kit, with the right to bring in an associate, is in a much stronger position than one sitting in the same chair every Tuesday for two years doing whatever the head of department asks.
Some clients now blanket-assess everything as inside because it is easier for them. You can still take the work. Just price it knowing the tax treatment is different, and do not pretend to yourself it is the same money.
Contracts: Two Pages Beats A Handshake
You do not need a twenty page agreement drafted by a City firm. You need something in writing that covers scope, price, payment and exit. Get a solicitor to draft a template once, then reuse it.
- What you will deliver, and just as importantly what you will not. “Policy review” means one thing to you and six weeks of extra work to the client.
- Payment terms in days, plus your right to charge statutory interest on late commercial payments, which runs above the Bank of England base rate.
- A cap on your liability, usually at the fees paid under that engagement. Without it, a £4,000 project carries unlimited risk.
- Who owns the work. Clients generally expect to own the deliverable. You should keep your own templates, models and methods.
- Notice on both sides, so a client cannot cancel a booked month the Friday before it starts.
And read your old employment contract before you approach anyone. Non-solicitation and non-compete clauses are common in senior roles, and the first clients an independent consultant naturally thinks of are exactly the ones those clauses were written to protect.
Where The First Three Clients Come From
Almost never from advertising. In the first year, the work comes from people who already know your name.
Start with ex-colleagues who moved on. The finance director you worked with four years ago is now at another firm with a problem you can fix and no procurement obstacle in the way. Then accountants and solicitors who serve your target size of client and get asked for referrals constantly. Then associate work: bigger consultancies subcontract delivery at a lower day rate, keeping a margin, and it fills a quiet month while you build your own pipeline. It is not glamorous and you cannot build a practice on it alone, but it pays.
Set yourself a weekly number instead of a vague intention. Five conversations a week, every week, whether the diary is full or empty. The month you stop is the month that shows up in your bank balance ninety days later.
Why An Independent Consultant Gets Judged Before The Call
Here is the difference between consulting and most trades. A plumber gets judged on the job. You get judged before anyone has spoken to you. The HR director who has been given your name will look you up that evening, and by the time you get on a call she has already decided whether you are a credible senior adviser or somebody between jobs.
A LinkedIn profile does some of that. A page you own does the rest, because it is the only place you control the whole story: the sectors you work in, two or three anonymised examples of problems you have solved and what changed, your qualifications and memberships, your insurance position, and a straightforward way to book a conversation. It does not need to be big. Five pages, written like a person, beats a brochure site nobody reads. That is the thinking behind our website design for consultants, and it is why the credibility question is worth settling before you start ringing round rather than during.
What The First Year Costs An Independent Consultant
Rough shape of the outgoings, so the day rate maths has something real behind it:
- Accountant for a limited company: expect four figures a year, less for sole trader self assessment only.
- Professional indemnity: a few hundred pounds a year for a low risk advisory practice, considerably more for IT, engineering or health and safety work.
- The ICO data protection fee, at whatever tier applies to you.
- Domain name at roughly £12 to £20 a year, and a site that is built, hosted and looked after for a monthly figure you can forecast.
- Accounting software, around £15 to £30 a month.
- Professional body membership, CPD and one decent conference.
Then the invisible cost: the gap between doing the work and getting paid. Corporate clients pay on 30 days from a correctly submitted invoice, and “correctly submitted” can mean a purchase order number you were never given. Three months of personal outgoings in the bank before you start is not caution. It is the thing that stops you accepting bad work at a bad rate in month four.
So What Should You Sort First?
In order: decide the sentence that describes what you fix and who for, pick sole trader or limited company based on who you intend to sell to, get professional indemnity in place, sort the ICO registration, set a day rate from 130 billable days rather than 220, and get a contract template you can send within an hour of a client saying yes.
Everything else can wait a month. The five conversations a week cannot, and neither can the fact that people will look you up before they call. If you want to talk any of it through, drop us a line.
