What Are PEFFs?

Items may not be visible

Property Embedded Fixtures and Fittings (PEFFs) refer to assets within a building that are part of the fabric of the property. These include items that may not be immediately visible. These could include electrical wiring, heating systems, plumbing, security systems, and other integral fixtures. Unlike removable equipment, PEFFs are considered embedded and contribute to the function of the building.

Why Older Buildings Hold Hidden Potential

Decades of improvements

Older buildings often come with decades of installations that have accumulated over time. Renovations, upgrades, and even original fittings can qualify as PEFFs for capital allowance claims. So, the potential for older buildings to hold hidden qualifying assets is significant because:

  • Historic installations may not have been claimed by previous owners.
  • Past documentation might be incomplete or not detail specific fixtures.
  • Renovation work could have added qualifying assets that remain unclaimed.

This makes older properties prime candidates for capital allowance reviews.

How Do Capital Allowances Work?

A significant tax relief

Capital allowances allow commercial property owners to offset the cost of qualifying capital expenditures against their taxable income. This can lead to significant tax savings. PEFFs fall under the category of “plant and machinery,” which can be claimed if specific criteria are met. However, the key is proving that these assets qualify, which can be complex without professional help.

Challenges and Solutions

Older buildings can pose more challenges

Claiming capital allowances on hidden PEFFs can be challenging for several reasons. First, older buildings might lack thorough records, making it difficult to identify eligible items. Second, the definitions of what qualifies as plant and machinery aren’t defined in law making it very complicated.

However, these challenges can be overcome:

  1. Specialist Surveys: Engaging a capital allowances specialist can help identify qualifying assets through a detailed survey. These experts understand how to assess hidden fixtures accurately and document them for claims.
  2. Historic Research: Tracing back renovation records and past improvements can reveal qualifying items that were overlooked.
  3. Collaboration with Professionals: It’s important to work with surveyors, accountants, and claims analysts. This helps ensure that the process of identifying and calculating the claim is efficient and maximises your potential allowances.

Is It Worth It?

Substantial savings

The tax benefits from claiming capital allowances on hidden PEFFs can be substantial. Especially for owners of older buildings who have not previously explored this opportunity. The one-off cost of hiring a specialist or investing time in an assessment can be recouped many times over through reduced tax bills.

Final Thoughts

Seriously consider PEFFs in older buildings

Many property owners overlook the value of embedded fixtures and fittings in their older buildings. Yet, taking the time to conduct a proper review can unlock significant tax savings. If you own an older property and haven’t yet considered capital allowances on PEFFs, it’s worth investigating. With the help of a professional, you can uncover hidden potential within your property and make the most of the tax benefits available to you.
