Selling a Cleaning Business: Due Diligence Checklist

If you are selling a cleaning business, due diligence is where a buyer checks the evidence behind the figures, contracts and day-to-day operation. Preparing early makes those checks easier and gives you time to explain gaps before they become last-minute obstacles.

This cleaning business due diligence checklist focuses on the records an established UK commercial cleaning company can organise before a sale. You do not need to send everything to every enquirer: begin with a high-level conversation, agree confidentiality arrangements and release sensitive information through a controlled process.

1. Make the financial story easy to follow

Prepare three years of annual accounts, recent management accounts and a comparison with the same period last year. Explain significant changes in turnover, margins and overheads. Reconcile the figures to supporting records rather than relying on a spreadsheet that nobody else can follow.

Keep a separate schedule of proposed profit adjustments. Identify owner employment costs that would stop, genuine exceptional expenses and any unusual income. Then allow for the cost of replacing the work you currently do. Dividends are not normally an operating expense, so they are not an operating-profit add-back.

A buyer will also want to understand profitability by contract or customer group. Revenue can grow while cash and margins weaken if additional hours, travel, supervision or materials are not reflected in pricing.

2. Build a clear customer and contract register

List each contract using a customer code initially. Include annual revenue, service scope, start and renewal dates, notice periods, pricing reviews and any known service concerns. Show the proportion of revenue represented by your largest customers and distinguish signed agreements from informal repeat work.

Keep executed contracts, variations and tender documents together. Flag assignment or change-of-control clauses for legal review; a share sale and an asset sale can raise different questions. Do not assume every customer must consent, or that every contract continues automatically.

Our guide to what happens to cleaning contracts when you sell looks at the continuity questions in more detail. For this checklist, the priority is a reliable register and access to the actual documents.

3. Show how staffing and service delivery work

Prepare an anonymised employee summary covering roles, hours, length of service, pay, holiday position and supervisory responsibilities. Explain how rotas are built, absence is covered and work is checked. Identify subcontractors separately and describe the arrangements supporting their work.

The buyer needs to see whether the team can maintain service after you leave. Record who recruits, trains staff, handles complaints and manages key accounts. If these tasks sit mainly with you, describe them openly so a realistic management plan can be costed.

Employment records and any transfer implications need specialist review appropriate to the proposed transaction. Avoid circulating names, payroll details or personnel files before there is a clear need and an agreed lawful approach to sharing them.

4. Check health, safety and quality records

Organise current risk assessments, relevant COSHH assessments, training records, accident records and insurance documents. Include site-specific requirements, equipment inspection records where applicable and evidence supporting any accreditations you claim.

Cleaning has practical risks involving chemicals, slips, manual handling and other activities. The HSE’s cleaning guidance is a useful reference when reviewing the records. The aim is to demonstrate what happens in practice, including how problems are reported and corrected.

5. Explain working capital and liabilities

Gather aged debtor and creditor reports, bank balances, borrowing schedules, finance agreements and details of tax balances. Explain overdue invoices, disputed balances and seasonal pressure on cash. Wages may need paying well before a customer settles an invoice.

List leased equipment, hire commitments and any guarantees or security arrangements for adviser review. Identify vehicles and machinery owned by the company, financed assets and anything owned personally by the seller.

Be clear about what the proposed price includes and how cash, debt and normal trading balances will be treated. Our guide to working capital when selling a cleaning business explains why a profitable company still needs cash to operate.

6. Document the systems that hold the business together

Create a practical outline of the software used for scheduling, time recording, payroll, invoicing and quality monitoring. Record who owns each account, how access is managed and whether the company can continue using the systems after completion.

Explain how keys, alarm codes and site access are controlled without placing sensitive credentials in an unrestricted folder. Identify important suppliers, outsourced services and business continuity arrangements. A simple process map can reveal dependencies that are difficult to spot in the accounts.

7. Protect confidentiality throughout due diligence

Use a secure third-party data room with named access, sensible permissions and a document index. Release information in stages, keeping a record of what was shared and when. An NDA is an important part of the process, but it does not remove the need to handle personal information properly.

The ICO’s guidance on acquisition due diligence and data sharing explains why data protection needs to be considered during a transaction. Agree the approach with your advisers before sharing identifiable employee or customer information.

8. Agree a realistic handover

Set out your current weekly responsibilities, the people who can take them on and the support you would be comfortable providing after completion. Distinguish an introduction period from an ongoing operational role. Record customer communication plans and any training the incoming team will need.

You can use our cleaning business handover guide to turn this into a practical transition plan. Clear expectations help protect service continuity and prevent different assumptions about your availability.

What should you prepare first?

Start with accounts and current trading, a coded customer register, an outline of your role and team, and a short list of material issues. Add the detailed evidence as the process progresses. Label missing items honestly and record who will resolve them; a transparent explanation is more useful than an incomplete file presented as final.

This checklist is a starting point rather than an exhaustive legal or financial due diligence request. The exact requirements depend on the business and the agreed transaction.
