Find out more about claiming Capital Allowances in your Commercial Office Building

What are Capital Allowances?

Capital Allowances are the only form of tax relief available to UK taxpayers on their expenditure on fixed plant and machinery. The cost of claimable items can be used to offset or reduce the taxable income or profits of the person or company that incurred the expenditure. Fixed plant and machinery encompasses numerous systems commonly found in most properties. In a commercial office some of the common items that form part of a claim are: air conditioning & heating systems, electric, lighting & plumbing, fixed furniture and fittings, key safe boxes, door bells & locks, intruder alarms, CCTV cameras and audio visual equipment.

Whilst many accountants and taxpayers are aware and claim on certain loose or moveable items, many are unaware that they can claim on embedded items within a property or property purchase. By entrusting your claim to STax, you are in safe hands. We bring together a team of surveyors, accountants, and property tax specialists, all equipped with a thorough understanding of the inner workings of over a century’s worth of case law relating to Capital Allowances.

Our 4 Step process


STax was introduced to me by my accountant, and they couldn’t have been more helpful in explaining the process and assembling my claim. The total claimed was over £250k, a sum I wasn’t even aware was available to me. I highly recommend their services.

STax simplified a highly complex area of tax for us and generated substantial savings. I was so impressed with the outcome of the survey that I’ve since introduced the firm to several of my business partners and investors.
