What markup do letting agents charge on maintenance?

Typical markups range from 10% to 20% on contractor invoices, covering coordination, quality assurance, and out-of-hours availability. Some agencies use a flat project management fee instead of a percentage markup.

Why do agencies lose markup revenue?

Common causes include invoicing the landlord at cost, forgetting to apply markup on rush jobs, contractor invoices not matched to work orders, and manual spreadsheet errors. Without per-job tracking, leakage is invisible.

Is maintenance markup taxable income?

Yes. Markup on maintenance work forms part of the agency's trading income and is subject to corporation tax or income tax depending on business structure. See our [[track-maintenance-costs-tax-england|maintenance cost tracking guide]] for record-keeping.

How much can automated invoicing recover?

Agencies moving from manual invoicing to work-order-linked billing typically recover 25–30% of previously lost markup within the first year, based on industry operational data.

Should markup be disclosed to landlords?

Transparency builds trust. Many agencies disclose their markup policy in terms of business. The [[tenant-fees-act-england|Tenant Fees Act 2019]] restricts tenant charges but does not cap landlord-facing maintenance markups.
