Trades admin is about to get heavier: how to claw the evening hours back

Another Tuesday night, another stack of paperwork

You know the evening routine. Ten hours on the tools, then the kitchen table becomes the office. A quote to write up, an invoice to send with the right VAT line, a customer to chase who said they'd "settle up at the end". That is the admin most trades businesses already carry, and it is real - typically around eight hours a week for a single tradesperson, mostly in the evenings, worth something in the region of one big quote's-worth of chargeable time every year.

What is changing is what sits on top of it. Two things are landing on trades businesses at the same time this year, and neither is optional.

The regulatory squeeze landing on top of the usual admin

If you work under the Construction Industry Scheme, you already know the drill: verify a subcontractor's status with HMRC before you pay them, deduct tax at the right rate - standard 20%, 30% if they are not registered, nil if they hold gross payment status - and file a CIS300 return every month, even in months with no activity. Get it wrong and HMRC's penalties start stacking from the first missed return. None of that is new. What is new is that it now sits alongside a second, bigger change.

Making Tax Digital for Income Tax Self Assessment became mandatory in April 2026 for self-employed people and landlords with qualifying income over £50,000 - a threshold that catches a large slice of subcontractors and sole-trader tradespeople outright. From April 2027 the threshold drops to £30,000, pulling in most of the rest, and a third phase drops it again to £20,000 from April 2028 - by which point most subcontractors earning above a part-time wage will be in scope. In practice that means quarterly digital record-keeping through compatible software, not once-a-year figures scribbled together in January. For a subcontractor already juggling CIS deductions on top of the usual quote-invoice-chase cycle, that is a genuinely new admin habit to build, not a tweak to an existing one.

Layer on the paperwork that was always there - Gas Safe Register notification for notifiable work, Part P sign-off with building control on electrical jobs, warranty documentation - and the evening pile is not shrinking. It is growing, at exactly the moment the trade is also short-handed.

Where the hours actually go in a working week

When we sit down with trades businesses in an assessment, the same handful of tasks show up again and again. As typical ranges, not universal figures:

• Quote writing. Measure up during the day, then sit down in the evening to price materials, list assumptions and type it up - 45 to 90 minutes per quote is common, and five quotes a week adds up to roughly half a working day gone before you have won a single job.
• Invoicing. Getting the description, VAT line and reference right, then sending it and remembering to follow it up - a small task each time, but it repeats across every job and every week.
• CIS verification and monthly returns. Checking a subcontractor's status, applying the right deduction, and filing the CIS300 - for a business running a handful of subbies, this is commonly an hour or two a month, more once MTD's quarterly reporting sits alongside it.
• Materials ordering and supplier admin. Phoning the merchant, sending the parts list, chasing next-day delivery - often 20 minutes a job that never gets billed to anyone.

None of these tasks is complicated on its own. The cost is that they are constant, they repeat with slight variations every time, and they all land after the earning day is already done.

What is safe to hand to AI, and what is not

This is the bit that matters more than any tool list. Not everything in that stack should go anywhere near automation, and being clear about the line is part of doing this properly.

Safe to automate, with a human still reviewing before it goes out: drafting a quote from a few bullet points instead of a blank page, generating and sending an invoice with the correct reference and VAT line, sending payment reminders that would otherwise be forgotten, and running a simple follow-up sequence for reviews or repeat work. These are drafting and reminder tasks. A person still checks the number and hits send.

Not safe to hand off, and this should never be treated as an AI task: determining a subcontractor's CIS status, filing the CIS300 return itself, signing off the accuracy of MTD digital records submitted to HMRC, or making the call on Gas Safe or Part P notifications. These carry legal and financial liability that sits with you, not with a tool. AI can help you organise the information faster - a tidy digital record instead of a shoebox of receipts - but the compliance decision and the filing stay yours. Any assessment worth paying for should draw this line explicitly, not blur it.

A trades-specific tool like TraidHand is built around this distinction: it helps with quote drafting and customer follow-up, the workflow layer, without pretending to make tax or compliance decisions for you.

One evening, before and after

Take the quote as a single worked example, because it is the task most trades businesses lose the most time to.

Before: you measure up on site, then sit down at the kitchen table that evening. You price the materials from memory or a supplier list, write out the scope in your own words, check the margin, and format it into something presentable. For a typical job, that is 45 to 90 minutes, and if the customer has a follow-up question the next day, another 10 to 15 minutes goes on top.

After: you dictate the job details into your phone from the van - room dimensions, materials needed, any complications - and a tool drafts a structured quote with a materials list and your usual margin already applied. You read it over, adjust anything that is off, and send it. The kind of shift we typically see in this workflow once it is set up properly is the drafting time dropping to ten minutes or so, with the editing and judgement call still firmly yours. Across five quotes a week, that is close to the half-day you were losing to quote writing alone - not gone, but recovered.

The same logic applies to invoicing and follow-up messages: a template and a trigger doing the repetitive part, you doing the part that actually needs a person.

Find your own number

Every trades business carries a different mix of this. A one-man band with no subcontractors will feel MTD more than CIS. A small outfit running three or four subbies will feel CIS verification and the monthly return more acutely, and will want that sorted before quarterly digital records land on top of it in 2027, and again as the threshold drops further in 2028.

The way to find your own number rather than a generic one is to actually map a week: what you do, when, and how long it takes. Our admin cost calculator for trades gives you a rough starting figure in a couple of minutes, based on your own rate and hours. For a fuller picture of where quoting time specifically leaks in a trades business, our post on where quoting time leaks for UK trades goes into the five most common fixes, ranked by effort.

If you want a proper look at your own week rather than an industry average, an AI workflow assessment for trades is a structured conversation about where your hours actually go, what is safe to automate and what needs to stay with you, and a prioritised plan in plain English. If you just want a quick read on where the pressure points sit before committing to anything, the free AI readiness quiz takes two minutes.

CIS is not going anywhere and MTD is only getting broader. The businesses that come through this comfortably will not be the ones that ignored the paperwork - they will be the ones that worked out early which parts of it a tool can genuinely help with, and which parts need a person checking the number before it goes to HMRC.
