What business software maintenance actually costs each month
Realistic UK cost ranges for ongoing software maintenance and what's usually included.
The short answer
Software maintenance costs typically run from around £30–£100 a month for a small tool needing light hosting and occasional fixes, up to several hundred pounds a month for a system with integrations, security updates and a support agreement. Budget for maintenance from the start; it is rarely optional once a system is in daily use.

What counts as software maintenance?
Maintenance usually covers hosting, security patches, fixing bugs that appear after launch, and small adjustments as your business changes. It does not normally include large new features — those are typically quoted and charged separately.
Small internal tool
- — £30–£100 a month
- — Light hosting
- — Occasional fixes
Business-critical system
- — £300+ a month
- — Guaranteed response times
- — Integrations to monitor
How much does software maintenance cost in the UK?
| System type | Typical monthly range |
|---|---|
| Small internal tool, light use | £30–£100 |
| Customer-facing system or portal | £100–£300 |
| System with integrations to other software | £150–£400 |
| Business-critical system with guaranteed response times | £300+ |
These are indicative ranges, not quotes. The right figure depends on hosting requirements, how many integrations need monitoring, and how quickly you need a fault fixed.
What does software maintenance cost cover in practice?
Most agreements bundle hosting, uptime monitoring, security patching and a set number of hours for small fixes each month. Anything beyond that, such as new features or a redesign, is usually quoted and billed separately once you agree the scope together.
“Budget for ongoing maintenance before you build, not after.”
What affects the cost most?
- How many other systems it talks to — each integration needs monitoring.
- Response time guarantees — same-day fixes cost more than best-effort support.
- How often the business rules change and need updating.
- Whether security patching and backups are included or billed separately.
What should a maintenance agreement include?
Get response times in writing, not just a promise to "sort it quickly". Clarify what counts as a bug fix versus a new feature, who owns backups, and what happens if you want to switch supplier later.
Can you reduce maintenance costs?
Keeping the system simple and avoiding unnecessary integrations is the biggest lever. A narrow, well-built tool generally costs far less to maintain than a sprawling one with features nobody uses.

Your questions
- How much does software maintenance cost per month?
- For a small UK business tool, typically £30–£400 a month depending on hosting, integrations and response time needs. Get a written quote rather than relying on ranges.
- Is maintenance optional once software is built?
- No, not realistically. Security patches, hosting and small fixes are needed to keep a system reliable and safe in ongoing use.
- What is usually not included in maintenance?
- Large new features are normally quoted separately from maintenance. Ask your supplier to define the line clearly in the agreement.
- How do I budget for software maintenance?
- Ask for a maintenance cost estimate alongside the build quote, before committing. Build it into your ongoing running costs, not as a surprise after launch.
