Business Advisory for Lambeth
Owner-managers in Lambeth facing a decision or a recurring problem: businesses that are busy but not profitable, owners considering a first or next hire, companies choosing between loan, invoice finance and investment, founders preparing to scale or to sell, franchisees and partnerships needing an independent view, and anyone who wants a quarterly conversation about the numbers with someone who has read them.
What is included
Everything inside the fixed fee
- A structured 90-minute session on the question you bring, with preparation from your numbers beforehand
- A written summary within three working days: what we discussed, what we recommend, what to do next
- Pricing and margin review: unit economics, price points, discounting and the gross margin you actually make
- Growth readiness review: hiring plans, funding options, systems, controls and what breaks at the next size
- Quarterly advisory retainer: a session each quarter with your management figures and a standing agenda
- Introductions to lenders, grant bodies and specialists where the question needs them
How it works
Business Advisory from Lambeth, step by step
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.
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.
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.
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
The IGI way of working, in Lambeth
No hourly rate and no surprise invoice. Lambeth clients know the fee for business advisory before they send a single document, and it stays fixed.
We work to the HMRC and Companies House calendar, not an appointment diary. Clients in Lambeth get reminders at 60, 30 and 7 days before each date that applies to business advisory.
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 business advisory: the person who prepared last year's work for your Lambeth business prepares this year's, and remembers what was agreed.
We explain business advisory in the words Lambeth business owners use, not in accountant's shorthand, and we show our working so you can check it.
Nothing is filed for Lambeth until you have reviewed and approved it. You see the draft, you ask questions, you sign off, then we submit and send you the receipt.

Worth knowing
Rules that come up in this work
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.
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Payments on account
Payments on account catch out most people in their second year of self-employment. HMRC assumes next year's tax will match this year's and collects half in January and half in July, in advance, on top of the balancing payment. If profits are dropping you can apply to reduce them, but reducing them too far attracts interest. We calculate the right figure rather than guessing.
Late filing penalties
Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
The VAT registration threshold
VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.
Questions
Business Advisory questions from Lambeth
Do you need to be my accountant for compliance?
No. Advisory is available on its own, and we work from management figures or accounts prepared by another firm. Where the session reveals a compliance issue we tell you, and where implementing the advice needs ongoing accounting we quote it separately as a fixed fee.
How do I get the most from a session?
Bring one clear question and send your figures beforehand. The best sessions are specific: should I take on this contract at this price, can I afford this hire by March, which of my three services should I stop. Broad questions get broad answers; specific ones get decisions.
Do you advise on selling a business?
We advise on preparing a business for sale: cleaning up the accounts, documenting what the buyer will ask for, understanding how value is calculated and what reduces it, and the tax position on exit including business asset disposal relief. For the transaction itself you need a corporate finance adviser or broker, and we work alongside them.
Can a session be about a partnership or shareholder disagreement?
Yes, where the question has a financial core: how profits are shared, how a partner is bought out, what a shareholding is worth, how to structure an exit. We give an independent financial view. Legal advice on the agreement itself needs a solicitor, and we tell you what to ask them.
What happens in the £149 session?
You tell us the question when you book and send your recent figures. We prepare, then spend 90 minutes by video working through it: the numbers, the options, the trade-offs. Within three working days you receive a written summary of the discussion, our recommendation and the next steps. One session often resolves the question; some lead to a review product.
What is the pricing and margin review?
For £299 we analyse your sales by product, service or customer against the true cost of delivering each, including the overheads that are usually ignored, to show where the margin is actually made and lost. The report recommends price changes, discount policy and which lines to grow or drop, with the profit effect of each quantified.
Which deadlines matter most for business advisory?
The next four dates that apply to business advisory are shown at the top of this page, calculated from today. For Lambeth clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
How do I get started from Lambeth?
Message us on WhatsApp or email with a sentence about your business and what you need. We reply in working hours with any questions and a fixed fee for business advisory. Once you confirm, we tell you exactly which records to send and the work begins. Most Lambeth clients are set up within a day.
