A business continuity plan is what keeps you trading when something goes wrong, whether that is a cyber attack, a flood, a power cut or a key system failing. It is not just for large companies. Small businesses are often hit hardest by disruption because they have less slack to absorb it. This practical guide walks through how to build a plan that actually works.
Put simply, a business continuity plan sets out how you keep trading through a disruption and recover afterwards. The NCSC guidance on backing up data is a good place to start on the IT side.
What is a business continuity plan?
A business continuity plan sets out how your business will keep its most important operations running during and after a disruption, and how it will recover fully. It answers three questions: what could stop us working, how do we keep going in the meantime, and how do we get back to normal. Done well, it turns a potential crisis into a manageable incident.
Why every business needs one
- Downtime is expensive, and small businesses feel it fastest.
- Cyber attacks, hardware failures and human error are common, not rare.
- Customers and insurers increasingly expect a plan to be in place.
- A clear plan removes panic and guesswork when something does happen.
How to build a continuity plan, step by step
- Identify your critical functions. List the activities you cannot operate without, such as taking orders, serving customers or processing payments.
- Assess the risks. Work out what could disrupt each function, from cyber attacks to power and premises issues.
- Set your recovery targets. Decide how quickly each function must be back (recovery time) and how much data you can afford to lose (recovery point).
- Put protections in place. This is where backups, disaster recovery, security and redundancy come in.
- Write the plan. Document who does what, key contacts, and step-by-step actions for the most likely scenarios.
- Test and review it. A plan you have never tested is a guess. Run through it, fix the gaps, and review it regularly.
The IT side: backup and disaster recovery
For most businesses, the biggest continuity risk is losing access to systems and data. Reliable, tested backups and a disaster recovery plan are the foundation, so that if a server fails or ransomware strikes, you can restore quickly rather than starting from scratch. The golden rule is that a backup you have never tested to restore is not a backup you can trust.
Common mistakes to avoid
- Writing the plan once and never testing or updating it.
- Assuming backups work without ever restoring from them.
- Focusing only on IT and forgetting people, premises and suppliers.
- Keeping the plan in one place that becomes inaccessible in a crisis.

Frequently asked questions
What is a business continuity plan?
It is a documented plan for keeping your most important operations running during a disruption, such as a cyber attack or system failure, and recovering fully afterwards.
Do small businesses need a continuity plan?
Yes. Small businesses often suffer most from disruption because they have less capacity to absorb it, so a simple, tested plan is well worth having.
What is the difference between business continuity and disaster recovery?
Business continuity is the broad plan for keeping the whole business running. Disaster recovery is the IT focused part, covering how you restore systems and data after an incident.
What are recovery time and recovery point objectives?
Recovery time is how quickly a function must be back up. Recovery point is how much data you can afford to lose, measured as the gap since your last good backup.
How often should I test my continuity plan?
Regularly, and at least once a year, plus whenever your systems change. Testing, especially restoring from backups, is the only way to know the plan actually works.
