Most small businesses do not have an IT budget; they have IT surprises. A laptop dies and gets replaced at panic prices, the Microsoft renewal lands unannounced, the server’s warranty quote arrives like a ransom note, and at year end the accountant totals a category nobody planned. The strange part is that IT is one of the most predictable costs a business has: the machines age on schedules, the licences renew on dates, the support is a flat monthly figure. It only feels chaotic because nobody wrote it down.
This guide fixes that: what a sensible SME IT budget contains, the realistic per-head numbers for 2026, and a template simple enough to actually maintain.
The budget’s six lines
A complete small-business IT budget needs exactly six categories. Most businesses track two of them.
1. Support
The managed service fee: for most SMEs, £50 to £85 per user per month at the standard tier, with basic cover from £30 and security-heavy arrangements to £150 (the full pricing breakdown explains the tiers). This is usually the largest line and the most predictable one.
2. Software and licences
Microsoft 365 (roughly £5 to £17 per user per month depending on tier, per the plan comparison), plus your line-of-business applications, accounting software and the subscription long tail. Two disciplines keep this line honest: an annual licence audit (15 to 30% savings are routine) and a rule that every new subscription gets written into the budget when adopted, not discovered at renewal.
3. Hardware provision
The line that converts panic into planning: machines replaced on a cycle (laptops and desktops roughly every 4 to 5 years, per the refresh guide) means budgeting roughly £150 to £250 per user per year as a standing provision (a £700 to £1,200 business machine, divided by its lifespan, plus peripherals and the occasional screen). Servers and network kit get their own provision if you still own any; businesses that went fully cloud largely retired this sub-line.
4. Connectivity and telephony
Broadband or leased line, failover, and per-user phone system costs: typically £60 to £400 monthly for the premises plus £5 to £20 per user for calls, per the connectivity and leased-line guides.
5. Security and compliance
Where not already inside your support tier: backup services, security tooling, phishing training, Cyber Essentials certification and renewal (a few hundred pounds annually plus preparation in year one), and cyber insurance if you carry it. Bundled properly into managed support this line shrinks; as ad-hoc purchases it sprawls.
6. Projects
The chunky, occasional items: office moves, migrations, phone system replacement, the Windows upgrade cycle. Unpredictable individually, but never zero collectively: a provision of 10 to 20% of the annual IT total absorbs most years, and known projects (that server replacement you have been deferring) get named and priced explicitly.
What the totals look like
Benchmarks vary by sector and dependency, but honest 2026 shapes for an office-based Scottish SME:
- Per-user annual total: commonly £1,200 to £2,500 per employee per year across all six lines, with cloud-light businesses at the bottom and regulated or security-heavy firms toward the top.
- A concrete 20-person example: support at £65/user (£15,600), M365 mixed tiers (£2,400), hardware provision (£4,000), connectivity and phones (£3,600), security and certification (£1,500), project provision (£3,500): roughly £30,600 a year, about £1,530 per head. Your numbers will differ; the shape rarely does.
- As a share of revenue, SMEs typically land in the low single digits of percent, higher for IT-dependent firms, and the comparison worth making is not against averages but against your own downtime cost: under-budgeted IT does not save money; it defers spending into incidents, which price at emergency rates.
Capex vs opex: the quiet shift
A decade ago IT budgets were capital-heavy: servers, PBXs, perpetual licences, bought in lumps and depreciated. The cloud era has shifted almost everything to operating expense: subscriptions, per-user fees, hosted everything, with hardware the last big capital item and even that increasingly leased or financed. The practical upsides for a small business: smoother cash flow, costs that scale with headcount in both directions, and far fewer five-figure surprise years. The discipline it demands in exchange: subscription sprawl is the new waste, which is what the audits in line 2 exist to catch.
The template, and the maintenance rule
The budget document itself is one page: the six lines, each with monthly and annual figures, renewal dates, and an owner. Two habits keep it alive: review it twice a year (once at budget-setting, once mid-year against actuals), and date-stamp the triggers: every contract renewal, warranty expiry and refresh due-date goes in the calendar of whoever owns the line. That second habit alone eliminates most of the surprises this page opened with, because IT surprises are mostly just diary failures with invoices attached.
If nobody in the business wants to own the document, that is itself information: it is the planning half of what a managed provider’s strategic reviews exist to carry.
Frequently asked questions
How much should a small business spend on IT per employee?
Commonly £1,200 to £2,500 per employee per year all-in for office-based SMEs in 2026, spanning support, licences, hardware provision, connectivity, security and a project reserve. Dependency drives the position in the range more than headcount does.
What percentage of revenue should go to IT?
SME norms sit in the low single digits of percent, rising with IT dependency. Treat percentages as sanity checks rather than targets; the six-line build-up from your actual estate produces a better number than any ratio.
Should hardware be budgeted as capital or spread monthly?
Either works; what matters is the provision existing. A per-user annual provision (or leasing, which converts it to opex mechanically) turns replacement into routine. The failure mode is neither method but no method.
What do small businesses most often forget to budget?
The hardware provision, the project reserve, and certification renewals: the three lines that arrive as “surprises” on a schedule that was always knowable. Backup and security also hide inside “support” assumptions that deserve checking.
How do we cut an IT budget safely?
From audits, not instincts: licence reviews, right-tiering support, retiring servers to cloud, and consolidating overlapping tools. The unsafe cuts (skipping backups, stretching hardware past support, dropping security layers) reliably cost more than they save, with interest.
Can our IT provider help build the budget?
They should be volunteering to: renewal dates, refresh schedules and realistic project pricing all live in their systems. Ours arrives as part of the strategic review, and the free IT health check produces the first draft from your actual estate.
