Understanding Computer Monitors Expenses
Computer monitors are a clear-cut business expense for any UK limited company where screen-based work is involved. HMRC treats monitors as plant and machinery, which means they qualify for capital allowances and, under the Annual Investment Allowance (AIA), can be fully deducted from your company's taxable profits in the year of purchase. There is no requirement to spread the cost over multiple years.
The business case for monitors is straightforward. If you or your employees use computers as part of your trade, additional or higher-quality monitors improve productivity and are a reasonable business expense. Whether you opt for a single ultrawide display, a dual-monitor setup, or a portable screen for working on the go, the full purchase price is deductible. HMRC does not set a maximum spend per monitor, but the expense should be proportionate to the work being done.
Personal use is the key boundary to watch. A monitor that sits on your office desk and is used for work is fine. A 65-inch screen mounted in your living room that you claim is for "business presentations" but primarily use for watching television would not pass scrutiny. If a monitor has genuinely mixed use, you should ideally apportion the cost, though in practice most directors who work from home use their office monitors primarily for business.
VAT-registered companies should reclaim the input VAT on monitor purchases. A £480 monitor from a UK retailer includes £80 of VAT that your company recovers on the next return. Always request a VAT invoice at the point of purchase, especially when buying online, as standard order confirmations may not include the supplier's VAT number.
From a compliance perspective, keep the purchase invoice, note the business purpose, and record the asset in your company's accounts. For monitors under £1,000, most accountants will simply expense them directly. Higher-value items might be recorded as fixed assets, but the AIA still allows full deduction in year one. If your company later disposes of the monitor, any proceeds would technically be a disposal for capital allowances purposes, though the amounts are usually immaterial.
Real-World Examples
Developer upgrading to dual monitors
Alex runs a software development consultancy through his limited company. He purchases two 27-inch 4K monitors at £350 each from Dell, totalling £700 including VAT. The company reclaims £116.67 VAT and deducts the £583.33 net cost from taxable profits, saving £145.83 in Corporation Tax.
Designer investing in an ultrawide display
Maria runs a graphic design studio and needs colour-accurate screens. Her company buys an LG UltraWide 34-inch monitor for £650 plus a monitor calibration tool for £180. Both are fully deductible business expenses as they are essential to her trade as a designer.
Portable monitor for client site work
A project manager who frequently works at client offices buys a 15.6-inch portable USB-C monitor for £220 to use alongside his laptop. This counts as business equipment and is fully deductible, as it is carried specifically for business travel and client-site work.
Common Mistakes to Avoid
- Buying a large TV and claiming it as a business monitor. HMRC can distinguish between a display used for work and one used for entertainment. If challenged, you would need to prove genuine business use.
- Failing to keep the VAT invoice, which means you cannot reclaim the VAT. Online purchases from marketplaces often only provide order confirmations, not proper VAT invoices.
- Not recording the purchase in company accounts at all, treating it as a personal expense. If your company pays, it should be in the company's books. If you pay personally, submit an expense claim to your company.
- Claiming monitors for family members or children's use as business equipment. Only monitors used by the director or employees for business purposes qualify.
Frequently Asked Questions
How many monitors can I claim through my limited company?
There is no fixed limit. You can claim as many monitors as your business genuinely needs. A developer with a three-monitor setup is perfectly reasonable. However, buying ten monitors for a one-person consultancy would raise questions. The expense must be proportionate to your business requirements.
Can I claim an ultrawide or curved monitor as a business expense?
Yes. HMRC does not restrict the type or specification of monitor you buy. Whether it is curved, ultrawide, 4K, or high refresh rate, as long as it is used for business, the cost is deductible. Many professional roles benefit from larger screens, and this is well understood.
Is there a benefit in kind if I use a company monitor at home?
Generally no. Computer equipment provided to employees for business use does not attract a BIK charge, even if there is incidental personal use. HMRC accepts that a monitor at your home office used primarily for work is a legitimate business asset without BIK implications.
Can I claim a monitor arm or mount as well?
Yes. Monitor arms, mounts, stands, and risers are all office equipment accessories. They are fully deductible in the same way as the monitor itself. Include them in the same expense claim or purchase order for simplicity.
What happens when I dispose of an old company monitor?
If you claimed AIA on the monitor, technically any sale proceeds should be brought into your capital allowances computation as a disposal. In practice, the second-hand value of monitors is low and this is unlikely to create a material tax adjustment. Donating old monitors to charity is also an option.
