HMRC Mileage Rates Update: Does This Really Help Small Construction Businesses?
The UK government has updated its travel, mileage and fuel allowance rates—but what does this actually mean for small construction businesses and the electrical industry?
While the changes were announced in May, they can be applied retrospectively from April, potentially affecting how businesses calculate and claim back travel expenses.
For electricians, apprentices, and small firms constantly on the move, mileage rates aren’t just administrative—they directly impact margins and take-home income.
So the key question is: Does this update genuinely support the industry—or does it fall short?
What Has Changed?
The latest guidance from HMRC outlines updated advisory fuel rates and mileage allowances.
👉 You can view the full government guidance here:
One important detail:
Although announced in May, the rates are backdated to April
This means businesses may need to:
Review previous mileage claims
Adjust expense reporting
Potentially reclaim underpaid amounts
Why This Matters for Construction and Electrical Businesses
Unlike office-based roles, electrical contractors and construction workers rely heavily on travel:
Moving between sites
Transporting tools and materials
Covering large geographic areas
For:
Small businesses
Sole traders
Apprentices starting out
Fuel and mileage costs can represent a significant portion of earnings.
Even small changes in rates can:
Improve cost recovery
Or leave businesses absorbing more expenses themselves
Does This Actually Help?
Here’s where it becomes less clear-cut.
✅ Potential benefits:
Backdating means businesses won’t lose out on earlier months
Updated rates may better reflect current fuel costs
Provides a clear framework for claims
⚠️ Potential drawbacks:
Many small businesses may not realise they can backdate
Administrative burden increases (adjusting past claims)
If fuel prices continue fluctuating, rates may still lag behind reality
For some, it’s helpful. For others, it may not go far enough.
The Hidden Challenge: Tracking Mileage Properly
One of the biggest issues isn’t the rate itself—it’s tracking mileage accurately.
Common problems include:
Forgetting to log journeys
Incomplete or estimated records
Lost receipts
This can lead to:
Underclaiming (losing money)
Or incorrect reporting to HMRC
Why Digital Mileage Tracking Is Becoming Essential
This is where tools like MileIQ come in.
Apps like this can:
Automatically track journeys in the background
Categorise trips (business vs personal)
Generate downloadable reports
Key advantages:
Saves time
Reduces manual admin
Creates HMRC-ready records
Helps ensure you're claiming everything you're entitled to
With updated rates now in place, accurate tracking becomes even more important.
What This Means for Learners and Apprentices
For electrical learners entering the industry:
Travel is often unavoidable
Costs can quickly add up
Understanding mileage claims early:
Builds better financial habits
Helps maximise income
Prepares learners for self-employed or subcontractor work
So—Is This a Positive Move?
The answer depends on your situation.
For some businesses, the update provides: ✔ A fairer reflection of costs
✔ An opportunity to reclaim expenses
For others: ✖ It may feel like a small adjustment in a bigger cost crisis
What’s clear is this: The benefit of these changes depends heavily on how well mileage is tracked and claimed.
Final Thoughts
The updated HMRC mileage rates are a useful step—but they’re not a complete solution.
For the electrical and wider construction industry, real value comes from:
Awareness
Accurate tracking
Making full use of available allowances
