Fixed Asset Accounting for Construction: Maximise Value From Plant and Equipment
Excavators, scaffolding, vehicles, and tools represent some of the largest sums tied up in a construction business, yet many firms track them loosely across spreadsheets or not at all. Our construction accountants build a proper asset register, apply the right depreciation and capital allowances, and make sure every purchase works as hard for your tax bill as it does on site.

Who We Are
Accountants who track your assets properly, not just at year end
Most construction businesses buy plant and equipment throughout the year but only think about how it’s accounted for when the accountant asks at year end, by which point receipts are missing and allocation guesses creep in. We maintain a live asset register throughout the year, so every purchase, disposal, and shared use across jobs is captured accurately as it happens.
Live asset register updated as equipment is bought or sold
Shared plant and tool costs allocated fairly across every project using them
The right depreciation policy protects your accounts and your resale value
Depreciating and Disposing Correctly
Plant and machinery depreciate at different rates depending on use and wear, and applying a single blanket rate across dissimilar assets distorts both your management accounts and your eventual disposal figures. Our specialist accountants for fixed asset accouting set depreciation policies specific to your asset types and update the register whenever equipment is sold, scrapped, or part exchanged, so your balance sheet always reflects reality.

Maximising Your Capital Allowances
Annual Investment Allowance, writing down allowances, and full expensing rules can turn a large plant purchase into significant tax relief in the year it’s bought, yet many construction businesses under-claim simply because purchases aren’t categorised correctly. On a contractor investing £80,000 a year in vehicles and equipment, correctly applied capital allowances can materially reduce the tax due on that year’s profits.
We review every asset purchase against current allowance rules before your accounts are finalised, ensuring nothing eligible is left unclaimed and your relief matches your genuine spending.

Common Pain Points
What Goes Wrong With Plant and Asset Accounting
Most fixed asset problems in construction come from a small set of recurring, avoidable gaps.
No Central Asset Register
Without one record of what’s owned, purchased, and disposed of, businesses lose track of assets worth thousands of pounds.
Shared Equipment Costs Allocated Unevenly
Plant used across multiple sites often gets charged entirely to one job, distorting profitability on every project involved.
Under-Claimed Capital Allowances
Purchases miscategorised or missed entirely mean businesses pay more tax than necessary on eligible spending.
Disposals Not Recorded Properly
Selling or scrapping equipment without updating the register overstates asset values and distorts year end accounts.
Depreciation Applied Inconsistently
Using the same rate across vehicles, tools, and heavy machinery produces figures that don’t reflect genuine asset wear.

Real feedback from real construction businesses
Over 60 verified five-star reviews from subcontractors, contractors and developers across the UK.

★★★★★
“We had no real idea which contracts were making money until they built us a proper job-costing system. Now we price the next tender based on actual data, not guesswork.”
★★★★★
“Every site brings its own VAT and SDLT questions, and they have never once been slow to answer. Switching from our old firm was the easiest financial decision we have made in years.”
FAQS
Main Questions about Fixed Asset Accounting for Construction
Why do I need an asset register if my accountant already does my year end accounts?
What capital allowances are available on plant and machinery?
Annual Investment Allowance and full expensing typically allow significant tax relief in the year of purchase, alongside writing down allowances on remaining balances.
How should I allocate the cost of equipment used across multiple sites?
Costs should be apportioned based on actual usage per project, usually tracked through timesheets, logs, or estimated usage percentages agreed in advance.
Does leasing equipment get treated differently to buying it outright?
Yes, lease payments are generally treated as an expense, while purchased assets are capitalised and depreciated, with different tax implications for each.
What happens to my accounts when I sell or scrap equipment?
The asset is removed from the register, any gain or loss on disposal is calculated, and this is reflected in your accounts and potentially your tax position
Can old, unclaimed capital allowances be claimed retrospectively?
In many cases yes, if the asset is still owned and the allowance was never claimed, though timing rules apply depending on the allowance type.
Why choose Construction Tax Accountants for fixed asset accounting?
We specialise in the specific asset patterns of construction businesses, from shared plant to seasonal equipment purchases, rather than applying generic small business fixed asset rules.
