Working from home as a director: expenses, equipment and rent

Start with the working arrangement, not the receipt

Establish why work is performed at home and what the employment arrangement requires. Working from home occasionally for convenience is not the same as an agreed homeworking arrangement with an employer. A director can be an employee of their own company, but must still apply the employment-expense rules rather than rules designed for a self-employed individual.

Distinguish the company reimbursing qualifying expenses from the director claiming personal employment-expense relief. Those routes have different conditions, especially where the homeworking is a choice. Record which duties are performed at home, the expected frequency, whether another workplace is available and what costs are genuinely additional. A blanket statement that every director can deduct a share of rent, mortgage and utilities is not a reliable starting point.

Identify additional costs rather than ordinary living costs

Under an eligible employer homeworking arrangement, qualifying additional household costs can include heating and lighting attributable to work and business calls. Costs that exist regardless of work, such as the ordinary mortgage payment or council tax, are not simply additional homeworking costs. Check HMRC’s current rules for an agreed fixed reimbursement amount versus claiming supported actual additional costs.

For actual costs, use a reasonable method grounded in use, not an arbitrary percentage selected to generate the largest deduction. A room count alone ignores hours, shared use and fixed charges. Keep bills and a note explaining how the additional business amount was estimated. A reimbursement should match the company’s policy and the applicable exemption; recording a private household bill as company expenditure does not create one.

• Separate fixed household costs from extra costs caused by the work.
• Exclude personal calls and ordinary domestic subscriptions.
• Keep the calculation proportionate and explainable.
• Recheck the current HMRC allowance before adopting a flat payment.

Treat equipment ownership and private use correctly

A laptop bought by the company for a director’s duties belongs to the company unless ownership is later transferred. Keep the invoice in the company records, record the asset where appropriate and distinguish capital-allowance treatment from a revenue expense. Equipment provision can have a different employment-benefit result from reimbursing an employee who bought an asset personally.

Consider whether private use is significant and whether the equipment is genuinely needed for the job. A company-funded gaming system or home entertainment subscription does not become work equipment merely because it sits in the office room. If equipment is sold or gifted to the director later, consider the transfer value and relevant benefit or tax rules. Maintain a short equipment register so ownership is clear when a director leaves, an accountant changes or the business closes.

Assess broadband, telephones and mixed-use services

A pre-existing home broadband contract normally costs the household the same amount whether or not the director works at home. That makes a claim for additional homeworking cost different from a new business service supplied under an eligible company arrangement. Avoid dividing every monthly subscription into business and personal percentages without reviewing the relevant employment-benefit rules.

Mobile phones also have particular rules depending on who holds the contract and what the employer provides. A company contract and reimbursement of a personal contract are not automatically equivalent. For mixed-use services, ask the accountant to explain the income-tax, employer and company-deduction position separately. The goal is a reliable treatment across the year, not a convenient one-off entry at the accounts deadline.

1. 1

   Identify the legal account holder for each service.

2. 2

   Check whether the service existed before homeworking.

3. 3

   Establish any genuine extra business charges.

4. 4

   Review employer provision versus personal reimbursement.

5. 5

   Apply a consistent policy and retain the supporting bills.

Understand what a rental agreement adds

A company can rent suitable space from a director where there is a real business arrangement, but rent received is not the same as a tax-free homeworking allowance. The director may have personal property-income reporting obligations. The rent must be supportable, the arrangement genuine and the company’s use consistent with its business needs. Seek advice before setting rent based on the maximum amount you would like to withdraw.

Review mortgage or tenancy terms, insurance, planning restrictions and any local rating implications. Exclusive business use of part of a home can affect private residence Capital Gains Tax relief; the details of use matter. A written agreement should cover the space, access, shared use, services, rent and termination. Do not create a retrospective lease to explain household bills already paid by the company.

Worked example: an additional-cost claim

Illustrative example: a director works from a shared spare room under an agreed homeworking arrangement. Their normal mortgage and broadband payment do not change. They retain evidence supporting £18 of extra work-related heating and electricity for the month and £7 of separately charged business calls. The potential actual-cost reimbursement under review is £25, not a fifth of every household bill.

The accountant checks whether the arrangement and evidence meet the employer reimbursement rules. The company also owns a laptop used for the director’s duties, which is recorded separately rather than included in the household calculation. If the director later proposes renting the room to the company, that is a new arrangement requiring its own legal, property-income and benefit review. This example illustrates separation of costs, not a universal entitlement to £25.

Review a homeworking claim across company and personal records

A director should prepare one description of the actual homeworking pattern and use it consistently. It explains where the work occurs, which duties are performed, whether the company has another workplace and which costs change because of the work. Supporting bills are useful only when the calculation distinguishes additional costs from ordinary household commitments. The accountant can then compare an eligible supported flat reimbursement with actual-cost evidence, rather than treating a room count as a universal tax rule. Any personal employment-expense claim is checked separately against its own requirements.

The director lists equipment and services by legal owner or contract holder. Company-owned equipment, a personally bought laptop reimbursed later, a company mobile contract and existing home broadband are different cases. The company keeps invoices and notes any meaningful private use. If a room rental is proposed, the director considers personal property-income reporting, reasonable terms, permission from the mortgage provider or landlord, insurance and exclusive-use consequences. A lease is reviewed before it starts; creating one at year end to justify unrelated payments does not provide a reliable evidence trail.

The resulting policy names the eligible costs, the evidence required, the payment route and the review date. For a company with employees as well as an owner-director, it applies defensible criteria consistently. Bookkeeping records the reimbursement, while payroll or benefits reporting reflects the relevant treatment where necessary. When the working arrangement changes, the policy is reviewed rather than automatically continuing old claims. The aim is a modest, supportable process that both the director and a future accountant can explain without guessing how domestic bills became company expenses.

1. 1

   Gather the records described above before making the decision.

2. 2

   Review the case-specific assumptions with the appropriate adviser.

3. 3

   Record the agreed action, responsible person and relevant dates.

4. 4

   Reconcile the outcome to the company’s actual records.

Build a policy that can withstand an enquiry

Keep the arrangement, expense policy and calculation together with the payment records. Reimburse through a clear expense process rather than irregular transfers labelled home office. Review the policy when working days change, the director moves, another office is opened or the company begins renting space. Ensure bookkeeping, employment reporting and personal tax reporting tell the same story.

For companies with several directors or employees, use consistent eligibility and evidence rules rather than more generous undocumented payments for owners. An accountant can review an efficient legitimate approach, including whether a supported fixed amount is suitable. The policy should explain the business reason and tax treatment in plain language so a future adviser can understand it without reconstructing several years of domestic expenditure.
