How it works

Cash-Flow Forecasting from Lambeth, step by step

  1. Tell us your situation

    A short message or call about what you do and what needs filing. We ask the questions that determine the right package and nothing more.

  2. Fixed fee in writing

    You receive one price for the work, confirmed by email before anything starts. It does not change if the job takes longer than we expected.

  3. Send records, review the draft

    Records come by WhatsApp or email. We prepare the draft, explain the figures in plain English and answer your questions.

  4. We file, you get the receipts

    Once you approve and the fee is settled, we submit electronically and forward the HMRC or Companies House acknowledgement the same day.

Why IGI

What you get in Lambeth

Deadline-first: the dates that matter for cash-flow forecasting are shown at the top of this page, diarised for every Lambeth client and chased before they arrive.

Online only, UK based. There is no office in Lambeth to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.

Continuity matters in cash-flow forecasting: the person who prepared last year's work for your Lambeth business prepares this year's, and remembers what was agreed.

Worth knowing

Rules that come up in this work

Crypto records and reporting

Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.

The 60-day property CGT return

The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.

Record keeping

Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.

Confirmation statements and identity verification

The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.

Allowable expenses

The expenses sole traders most often miss are home working costs, claimed by actual proportion or HMRC's flat rate, the business share of phone and internet, mileage at 45p for the first 10,000 business miles, and training that maintains existing skills. The ones most often claimed wrongly are commuting, entertaining customers and clothes that could be worn outside work.

CIS deductions

Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.

Employer National Insurance

Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.

Questions

Cash-Flow Forecasting questions from Lambeth

Why do forecasts usually go wrong?

Three reasons: they assume customers pay on the due date, they forget tax dates, and they are never updated. We model actual payment behaviour from your history, place VAT, PAYE, Corporation Tax and Self Assessment payments on their real dates, and offer the refresh retainer so the forecast stays current.

Do I need bookkeeping with you to have a forecast?

No, but the data must exist. We build forecasts from any reasonably kept accounting file plus bank data. If the bookkeeping is behind, we say so first, because a forecast built on stale records is worthless. Clients in our bookkeeping service have the data ready by default.

What is in the funding-application pack?

For £299: a 12-month forecast with monthly cash flow, profit and loss and balance sheet, an assumptions schedule, sensitivity analysis showing what happens if sales fall or costs rise by set percentages, and a narrative explaining the business and the use of funds in the terms lenders and grant bodies use. We brief you on the questions they will ask.

Will banks accept your forecasts?

Yes. Lenders see forecasts constantly and recognise one built from real data with documented assumptions. Grant bodies and investors likewise. We produce covenant calculations and any specific format a lender requires, and we are happy to speak to the lender with you about the assumptions.

What does the 12-month forecast add?

The £349 forecast extends the horizon to a year, monthly, with three scenarios: base case, a downside with slower sales or payment, and an upside, so you can see the cash effect of the things that might happen. It includes a profit and loss and balance sheet forecast alongside the cash, and is the basis for the funding pack.

What is the monthly refresh retainer?

For £99 a month we replace each month's forecast with the actual figures, roll the horizon forward, update the assumptions for what has changed and send you the refreshed forecast with a short note on the movements. A forecast that is not refreshed is out of date within weeks; the retainer keeps it live.

Do you have an office in Lambeth?

No. IGI Accounting is an online-only firm. We serve Lambeth and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for cash-flow forecasting is the same in Lambeth as anywhere else in the country, and why there is nothing to visit and nothing to print.

Is cash-flow forecasting in Lambeth really the same price as elsewhere?

Yes. The fee published on this page is what a client in Lambeth pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
