There is no standard figure for the cost to start a business UK founders should expect. A home-based consultant may need relatively little upfront capital, while premises, stock or specialist equipment can raise the requirement significantly. For eligible founders, start up business loans can be one funding option to consider.
What Should Your Startup Budget Include?
Start by separating one-off setup costs from recurring monthly expenses. This shows what must be paid before launch and what the business will need to cover once trading begins.
For illustration, not as a benchmark, consider how two different businesses might approach their initial budget:
| Cost area | Home-based consultant | Small shop |
| Equipment and technology | £1,000 | £3,000 |
| Initial stock | £250 | £4,000 |
| Deposit or premises costs | £0 | £3,000 |
| Website and branding | £750 | £1,000 |
| Insurance and setup costs | £500 | £750 |
Actual costs vary by location, business model and supplier.
Some statutory costs are small by comparison. Online incorporation of a private limited company currently costs £100 through Companies House. This is the statutory fee only; formation agents may charge separately. If a business is required to pay the ICO data protection fee, the tier 1 fee is currently £52, although exemptions can apply.
Figures correct as of 21 September 2026.
Turn Costs Into a Funding Requirement
Once costs are listed, put them into a timeline. Mark which payments are needed before launch, which recur each month and which could be delayed.
A 12-month cash flow forecast can bring these figures together. Early sales should be realistic and conservative rather than assuming identical revenue every month. The founder also needs to consider working capital while sales build.
Which Funding Options Could Help?
Funding may come from personal investment, business revenue, grants where available or borrowing.
For eligible UK founders, a Government-backed Start Up Loan is one borrowing option. Current 2026 terms provide £500–£25,000 per founder at a fixed 7.5% AIR (annual interest rate), with repayment over one to five years. Eligible co-founders can apply separately, potentially allowing up to £100,000 across four founders. Approved loans also include 12 months of free mentoring.

Representative Example – Personal Loan for Business Use Only: £10,000 repayable over 60 months at 7.8% Representative APR. 60 months at the AIR of 7.5% p.a. for fixed monthly payments of £200.45. Total cost of credit of £2,027 and total amount payable of £12,027. Finance subject to status and 18+ only. No arrangement fees or early-repayment penalties.
A Start Up Loan is a personal loan for business purposes rather than a grant. The borrower remains responsible for repayments even if the business stops trading.
Remember Your Own Living Costs
If the business is expected to provide an income, household finances matter too.
A personal survival budget records continuing household income and regular outgoings. Income that will stop when employment ends should not be treated as continuing income. Any resulting shortfall can help establish what the business may need to provide as founder income and should connect with the cash flow forecast.

Start With the Real Funding Gap
The cost to start a business UK founders face depends on the business model, setup requirements and timing of revenue. Use actual costs where possible, label estimates clearly and separate one-off spending from ongoing commitments.
Then test the resulting funding gap against a realistic 12-month cash flow forecast. The aim is not to find the biggest amount available, but to understand what the business genuinely needs and what its expected cash flow can reasonably support.
