What is a business broadband SLA?
A business broadband SLA is a service level agreement. It is the part of your contract that says what level of service the provider is promising, and what happens if it misses it.
Most people choosing business broadband compare the speed and the monthly price, then sign. The SLA is the page nobody reads until the line is down on a Monday morning. That is the Do-Nothing Default again, and it is a costly moment to find out what your fix time really is.
This guide uses Ofcom’s advice for businesses on contracts, which we read on 5 November 2026. That page was first published on 21 September 2015 and last updated on 26 June 2026, and Ofcom’s General Conditions page sets out the formal rules behind it. Ofcom says only half of SMEs are aware of SLAs, so you are not alone if this is new.
What does a business broadband SLA cover?
Ofcom says an SLA defines the terms of the service you are being provided and outlines support and how problems are resolved. It lists the issues an SLA may include.
- Fault repair and installation times: how quickly the provider commits to fix a fault or install the line.
- Queries and complaints: how quickly the provider acts on them.
- Coverage levels: the footprint the service is expected to reach.
- Speed of connection: the speed the service is expected to deliver.
- Maximum days without service: the longest the line can be down.
Not every business broadband SLA has all of these, and the words vary. Ofcom says your contract may come with an SLA, so look at what each package actually includes.
What is a service level guarantee?
Ofcom says an SLA can be accompanied by a service level guarantee, or SLG, and that SLAs usually include compensation if they are not met.
That is the difference between a promise and a promise with something behind it. An SLA on its own tells you what the provider aims for. The guarantee tells you what you might get if it falls short.
Ofcom does not give figures here, because they differ by provider and by package. Ask what the compensation is, how you claim it, and whether it has a cap before you sign.
Key takeaways
- A business broadband SLA says what service the provider promises.
- A service level guarantee usually sets out compensation if it is missed.
- Ofcom says better care levels often come at a premium price.
- Ask for the SLA in writing before you sign.
Do you have to pay extra for a business broadband SLA?
Often you do. Ofcom says providers offer packages with improved care levels at a premium price, and different packages may come with different products purchased.
So the lowest priced plan on a comparison page can carry a lighter SLA than a dearer one. Whether the extra is worth it depends on how much an hour of downtime costs your business. A shop with a card machine on the line has a different answer from an office that can work from phones.
Ofcom’s advice is to ask your provider about SLAs and the level of ongoing service you can expect. Treat the business broadband SLA as a line in the price, not a footnote.
What can you ask a provider about a business broadband SLA?
Ofcom says all businesses are entitled to ask for certain information to be included in their contract in a clear, comprehensible and easily accessible form. That includes whether any services might be limited or restricted, and the minimum service quality levels, such as ongoing service quality and the initial connection time.
It also includes the customer service and maintenance service that comes with the contract, the contract length and renewal conditions, and any charges due on termination, including early termination charges.
Ofcom’s General Conditions page adds a duty that sits behind all of this: providers must publish information about their standard contracts for small and medium firms, including any service level agreements and guarantees, such as for loss of service. They must give it free of charge, in a durable medium, to any SME customer entering a contract.
A short list of questions makes this easy to use:
- What is the fault repair time, and does it count working days or calendar days?
- Is there a maximum number of days without service?
- Is there compensation if the SLA is missed, and how do you claim it?
- Is the SLA on this plan or only on a higher one?
Keep the answers in writing. If anything is unclear, do not sign until you understand the terms.
How does the SLA fit with the rest of your contract?
An SLA sits alongside the other terms, so read it with them. Ofcom says that if you are a small business with ten employees or fewer, your contract should not exceed 24 months and should not be extended when you buy an additional service unless you have consented.
Ofcom also says that if you are in that group, your provider cannot renew landline or broadband contracts automatically. It must get your consent for each new minimum contract period.
That matters for a business broadband SLA because a weak one is easier to live with on a short contract.
