Making Tax Digital: What UK Heating & Plumbing Businesses Need to Know
If you’re a sole trader, the recent Making Tax Digital (MTD) changes are likely to affect the way you run your business.
Running a heating or plumbing business already involves enough admin, so changing the way you run and report your business can seem like a daunting task.
In this guide, we cover exactly what’s changing, who it affects, and how you can make your life easy going forward with MTD.
What Is Making Tax Digital?
Making Tax Digital is HMRC’s programme to modernise the UK tax system. Instead of relying on paper records or a once-a-year tax return, MTD requires businesses to:
- Keep digital records
- Use approved software
- Submit quarterly updates to HMRC
The goal is to reduce errors and give both HMRC and businesses a clearer picture of tax obligations throughout the year.
Making Tax Digital was already mandatory for VAT-registered businesses, but many sole traders don’t fall into that category. Importantly, these new changes do not affect how much tax you pay — only how information is recorded and submitted.
How do the MTD Changes Affect Sole Traders?
From April 2026, Making Tax Digital for Income Tax is set to apply to sole traders and landlords. This change will affect many self-employed plumbers and gas engineers across the country.
New Income Thresholds and Start Dates
MTD is being introduced in stages:
- From April 2026
Businesses with annual self-employed income over £50,000 will be required to follow MTD rules.
- From April 2027
Businesses with annual self-employed income over £30,000 will be brought into MTD ITSA.
If your turnover is below these thresholds, these changes won’t apply to you yet — but HMRC has made it clear that thresholds may lower again in the future. Read more on the HMRC website.
What Will Making Tax Digital Require You to Do?
If you already run your business through Gas Engineer Software, this is simply a change in reporting. Those still primarily running their business on paper will need to change some core workflows. New requirements include:
- Keeping digital records of income and expenses
- Using MTD-compatible accounting software (Xero, QuickBooks, and Sage are all good options)
- Submitting quarterly updates to HMRC
- Completing an end-of-period statement
- Making a final declaration confirming all income for the tax year
This replaces the traditional “once-a-year” Self Assessment approach.

How to Make the Change Simple and Straightforward
For most trades, the impact of MTD isn’t about learning tax rules — it’s about how organised your records are.
MTD makes it impractical to rely on paper or manual systems, and the quarterly reporting means missing invoices stand out sooner, late or forgotten payments cause more friction, and disorganised records create stress more often, not just once a year.
How Gas Engineer Software makes MTD easier
To comply with MTD, you’ll need two things:
- MTD-compliant accounting software such as Xero, QuickBooks, or Sage.
- A way to keep income and expense records digitally.
Gas Engineer Software helps with the second, providing an easy way to handle your invoices and track payments.
With the help of our accounting integrations, this data is then automatically transferred to your accounting software. From there, you can easily submit your quarterly reports and final tax statements.
What are the benefits of this system?
Gas Engineer Software doesn’t submit tax data to HMRC or replace your accountant. Instead, it helps keep your day-to-day business records organised at the source:
- Jobs are logged properly
- Invoices created as work is completed
- Payments tracked against the correct jobs
- Customer records kept consistent
When this data syncs automatically into your accounting software:
- Quarterly updates are less disruptive
- Fewer errors need fixing later
- You or your accountant can work with clean, complete records
In short, it’s all about removing the chaos that makes tax stressful.
Get Ahead of Making Tax Digital
As a heating and plumbing businesses owner, you aren’t expected to become a tax expert. Rather, by keeping work, invoices, and payments organised, much of Making Tax Digital takes care of itself.
