How do I set a consultancy day rate?

Start from the annual income you need, add your fixed costs, and divide by the number of days you can realistically bill — typically 120 to 140 in year one, not 220. That gives the rate the business requires. Then check it against what the market pays for your discipline and seniority. If the two are far apart, the problem is usually the billable day assumption.

What utilisation rate should a consultancy plan for?

Around 55% to 70% for an established practice. First year is commonly 40% to 50%, because selling, proposal writing and admin take real time and the pipeline has not matured. Planning for 80% is how consultancies end up cash-poor in month seven.

Do I need professional indemnity insurance as a consultant?

It is rarely a legal requirement but almost always a contractual one. Most corporate clients specify a minimum level of cover in their standard terms and will not raise a purchase order without seeing the certificate, so treat it as a cost of trading rather than an optional extra.

Should I be a sole trader or a limited company?

A limited company gives liability protection and is often a condition of engagement with larger clients, but costs more to run and brings IR35 considerations. Sole trader is simpler and cheaper at lower profits. The right answer depends on your profit level, how much you draw and who your clients are, so it is worth modelling both.

How much do I need saved before going independent?

Six to nine months of household costs is the usual guidance, and the reason is negotiating position rather than survival. A consultant with three months of runway takes the first project offered at whatever rate is proposed. One with nine months can hold a rate, which compounds across every engagement that follows.

By industry

Consultancy Business Plan

A consultancy has almost no startup cost and almost no margin for error in its assumptions. The whole plan turns on two numbers — your day rate and how many days you actually bill — and optimism in either is what turns a viable practice into an expensive year.

What the plan has to prove

Consultancies rarely borrow much, so the plan is usually being written for the founder, a spouse, or an accountant asked whether this is sensible. It still has to survive the same scrutiny, and the scrutiny lands in a different place from a capital-heavy business.

A billable day count you can defend. There are around 220 working days in a UK year after holiday and bank holidays. Selling, proposal writing, admin, invoicing and marketing take a large share of them. A first-year plan assuming much more than 120 to 140 billable days is describing an outcome, not a forecast.
Where the first three clients come from. Named, not categorised. A plan that says the target market is UK SMEs has not answered the question. A plan that says two former employers have already asked about availability has. Pipeline specificity is the single most convincing thing in a consultancy plan.
Concentration risk. A practice where one client is 70% of revenue is a job with extra paperwork and no employment rights. Show how the mix broadens, and what the cash position looks like if the largest client leaves at ninety days notice.
The gap between winning work and being paid. Corporate clients pay on 45 to 60 days and some run 90. Between doing the work and receiving the money there can be a quarter of a year, and that gap has to be funded from somewhere.

Typical startup costs

Costs are low enough that the real investment is the months of income forgone while the pipeline builds. Budget for that first, and the equipment list second.

Cost	Typical range	What drives it
Professional indemnity insurance	£300 – £3,000 per year	Driven by discipline and cover level. Management consultancy sits low; anything touching financial, engineering or safety advice sits far higher, and many clients specify a minimum.
Company formation and accountancy	£600 – £2,500 per year	Incorporation, annual accounts, corporation tax return, payroll and VAT filing.
Laptop and equipment	£1,000 – £3,000	Usually the only meaningful capital purchase, and generally cheaper than the tax relief conversation it generates.
Website and brand	£500 – £8,000	A credible site matters more in consultancy than most sectors because it is frequently the only thing a referred prospect sees before the first call.
Software and subscriptions	£600 – £3,000 per year	Office suite, accounting, CRM, video conferencing and any discipline-specific tools.
Marketing and business development	£1,000 – £10,000 per year	Conferences, memberships, travel to meetings that do not convert. Consistently underestimated.
Personal drawings during ramp-up	£15,000 – £40,000	The genuine cost of starting. Six to nine months of household costs before billing reaches a steady level.

Indicative UK ranges for a solo or small consultancy. Professional indemnity cover in particular varies enormously by discipline.

The numbers that decide whether it works

These are the figures a lender turns to first, and the ones SquarePlan calculates for you as you enter your sales and costs.

Utilisation rate: Billable days as a share of available working days. Around 60% is a healthy established practice; 75% usually means nobody is selling and there will be a gap in three months. First year is commonly 40% to 50%.
Day rate: Varies hugely by discipline and seniority. Work backwards from the income you need divided by the days you can realistically bill, then check the answer against what the market pays, rather than starting from a competitor's price list.
Overhead recovery per billable day: Annual fixed costs divided by forecast billable days. This is what every day has to cover before it earns anything, and it is the figure that shows why discounting a rate by 15% can remove most of the profit.
Debtor days: Average time between invoice and payment. It has no effect on profit and a decisive effect on whether you can pay yourself, which is why the cash flow matters more than the profit and loss in a consultancy plan.

Licensing and regulation

Consultancy is largely unregulated as an activity, but the tax and contractual position around it is not, and getting the structure wrong is more expensive than anything else on this page.

IR35 and off-payroll working: Where you work through your own limited company for a medium or large private-sector client, or any public-sector body, the client determines your employment status for tax. If they assess the engagement as inside IR35, tax and National Insurance are deducted at source and your net position changes substantially. Model both cases before assuming a rate is equivalent to a salary.
Professional indemnity insurance: Not a legal requirement for most disciplines, but a contractual one for most clients. Corporate procurement commonly specifies a minimum level of cover and will not issue a purchase order without a certificate.
Choice of legal structure: Sole trader is simpler and cheaper to run; a limited company offers liability protection and is often required by larger clients as a condition of engagement. The tax difference varies with profit level and how much you draw, so it is worth modelling rather than assuming.
VAT registration: Registration is compulsory once taxable turnover passes the threshold, and consultancy day rates reach it faster than people expect. Where your clients are VAT-registered businesses, registering has little downside and the Flat Rate Scheme may be worth comparing.
Data protection: Handling client personal data means registering with the ICO and paying the annual data protection fee. Cheap, frequently forgotten, and something client due diligence questionnaires ask about directly.

The two assumptions everything rests on

A consultancy plan is short because the business is simple, and that simplicity is deceptive. There are only two variables of consequence — the rate you charge and the days you bill — and they multiply, so an error in each compounds into an error the size of a salary.

The rate is the easier of the two, because the market constrains it. Ask around, look at what recruiters quote for interim equivalents, and you will land within a reasonable band for your discipline. The billable day count is where plans go wrong, because nothing constrains optimism. It feels reasonable to assume you will work four days a week and sell on the fifth. In practice the selling does not fit into one day, projects finish and the next one starts three weeks later, and August and December are quiet whatever your pipeline looks like in June.

Start from 220 working days. Take off holiday you actually intend to take. Take off the time genuinely spent on proposals, invoicing, accounts, marketing and professional development. What remains in a first year is commonly 120 to 140 days. Build the plan on that, and treat anything above it as upside rather than as the base case.

Overhead recovery, and why discounting hurts

Fixed costs divided by billable days gives the amount each day has to earn before it contributes anything. For a practice with £14,000 of annual overheads and 130 billable days, that is roughly £108 a day.

This is worth calculating explicitly because of what it does to discounting. Drop a £700 day rate to £600 to win a piece of work and it looks like a 14% concession. Against the roughly £592 that day actually contributes after overhead recovery, it is closer to a 17% cut in what you take home — and if the discount becomes the reference price for the next proposal, it persists. Knowing the recovery figure makes that trade-off visible at the moment you are deciding, rather than at the year end.

Profit is not the problem, cash is

A consultancy can be comfortably profitable and unable to pay the founder, because corporate clients pay slowly and payroll does not. Work delivered in March, invoiced on the last day of the month against 60-day terms, is money arriving at the end of May. Meanwhile you have paid yourself, paid the accountant and paid the insurance.

The plan therefore needs a monthly cash flow, not just a profit forecast. It should show the trough, show what a single late payer does to it, and state where the cover comes from — savings, an overdraft, or an invoice finance facility arranged in advance. Consultancies that get into trouble are almost never unprofitable. They have simply run out of money while waiting to be paid.

Where SquarePlan fits

You enter your day rate, your realistic billable days by month, your fixed costs and your expected payment terms. SquarePlan builds the monthly cash flow, the break-even point and the profit and loss, with VAT and the tax position calculated underneath. Change the utilisation assumption from 60% to 45% and you see immediately what it does to the year — which is the test worth running before you resign, not after.

How this gets funded

Most consultancies are self-funded, and the thing being funded is not equipment but the months before revenue arrives.

Personal savings: The usual route. The plan should state explicitly how many months of household costs the reserve covers, because that number sets how long you can hold your rate before accepting underpriced work out of necessity.
Start Up Loan: £500 to £25,000 per person at 6% fixed over one to five years, with mentoring. Well suited to bridging the ramp-up period, and the application requires exactly the cash flow forecast you should be building anyway.
Invoice finance: Advances a percentage of an unpaid invoice for a fee. Expensive as a permanent arrangement, but relevant if you land a large client who pays on 90 days and you cannot fund the gap.
Business overdraft or credit card: A modest facility to smooth the gap between doing the work and being paid. Arrange it while you have income to show, not when you need it.
