Thatcher Self-Employed Tax in the UK (2026/27)
How self-employed thatchers are taxed in the UK for 2026/27, covering CIS, straw and reed materials, ladders and scaffolding, and irregular seasonal income.
CIS: Subcontracting vs Direct Homeowner Work
Whether the Construction Industry Scheme applies to a thatcher's work depends on who's paying them. Work carried out directly for a private homeowner, with no contractor in the chain, generally falls outside CIS — you invoice and are paid gross, then declare the income through Self Assessment as normal. Where a thatcher subcontracts for a building or roofing contractor as part of a larger project, CIS is more likely to apply, meaning the contractor deducts tax at source (20% for registered subcontractors, 30% if unregistered) before paying you, with the deduction reconciled against your eventual Self Assessment bill.

Water reed, combed wheat reed or long straw, along with hazel spars, sways and wire netting used to secure a roof, are direct job costs deducted from turnover before arriving at taxable profit. Because material costs and sourcing can vary significantly between a water reed roof and a traditional straw roof, keeping clear job-by-job records helps when working out true profit margins as well as for tax purposes.
Access Equipment and Insurance
Ladders, scaffold towers and other access equipment used for the business are generally allowable — either deducted directly for smaller items or claimed through capital allowances for equipment expected to be used across multiple years. Public liability and professional indemnity insurance, which many thatchers carry given the trade's fire-risk profile, is also generally an allowable expense where the policy is wholly for business purposes.
Managing Irregular, Weather-Dependent Income
Thatching depends heavily on dry, settled weather, and bookings can be irregular — a run of good weeks followed by a rained-off month is a normal part of the trade. Because Self Assessment tax is paid well after the income was earned, setting aside a fixed percentage of every job's payment as it comes in, rather than assuming a lump sum will be available later, helps avoid a cash-flow squeeze when the tax deadline arrives.

Frequently asked questions
Does the Construction Industry Scheme apply to thatching work?
It can, where a thatcher is subcontracting for a building contractor rather than working directly for a private homeowner. If CIS applies, the contractor deducts tax at source (20% if registered, 30% if not) before paying you, reconciled against your final Self Assessment bill.
Can a thatcher claim the cost of reed and straw materials against tax?
Yes — water reed, combed wheat reed, straw and fixing materials (spars, sways, netting) bought for a specific job are a direct cost of the work, deducted from turnover before arriving at taxable profit.
How is scaffolding and access equipment treated for tax?
Ladders, scaffold towers and other access equipment used for the business are generally allowable, either as a direct expense for smaller items or through capital allowances for equipment expected to last several years.
Do thatchers need specific insurance, and is it tax-deductible?
Public liability and professional indemnity insurance are standard for thatching given the fire-risk profile of the trade, and premiums paid wholly for business purposes are generally an allowable expense against taxable profit.
How should a thatcher manage tax with irregular, weather-dependent bookings?
Since thatching work depends heavily on dry weather and bookings can be irregular across the year, many thatchers find it useful to set aside a fixed percentage of each job's income for tax as it's earned, rather than relying on a lump sum being available when the Self Assessment bill falls due.
