Not all leased line quotes are created equal. While most UK providers are reputable, there are instances where quotes include misleading terms, hidden charges, or overly optimistic promises. Here’s how to identify red flags in leased line quotes before you commit.
1. Vague or Missing Service Level Agreements (SLAs)
SLAs are critical because they define uptime guarantees, fault resolution timelines, and response times. If your quote includes generic terms like “high reliability” or lacks specific uptime targets and fix-time guarantees, be cautious.
Red flag examples:
- No mention of uptime (e.g. 99.9%)
- No stated repair time (e.g. 4 hours)
- Support hours not listed
Best practice: Insist on a written SLA document with performance metrics.
2. Unexpected Installation or Setup Fees
Many leased line quotes promote low monthly rates but quietly include:
- High installation fees (sometimes over £2,000)
- Excess construction charges (ECCs) if extra cabling is needed
- Equipment hire or purchase fees
Red flag examples:
- Installation: “TBD after survey”
- Router: “Provided at additional cost”
Tip: Ask for a full cost breakdown, including ECCs, in writing.
3. Non-Committal Pricing or “From” Prices
Quotes that say “from £249/month” often indicate pricing is based on the best-case scenario. The final price may rise significantly after the site survey.
Red flag phrases:
- “Estimated pricing only”
- “Subject to change”
- “Indicative only, excludes site visit”
Solution: Confirm if the price is fixed or conditional upon survey.
4. Missing Contract Length and Terms
A proper quote should clearly state:
- Contract length (12, 24, 36 months)
- Notice period
- Early termination fees
Red flags include:
- No contract duration listed
- Ambiguous clauses around price increases
Make sure the quote includes a clear commercial contract or draft agreement.
5. No Mention of Contention Ratio or Dedicated Bandwidth
Leased lines are supposed to be uncontended—meaning bandwidth is not shared. Some quotes sneak in “up to” language or shared service models.
Red flag wording:
- “Up to 1 Gbps”
- “Shared fibre”
Ask directly: Is this a 1:1 dedicated connection? Demand confirmation.
6. No Site Survey Details
Most accurate quotes depend on a physical or desktop site survey. If the quote skips this, surprises are likely later on.
What to ask:
- Will a site survey be conducted before finalising costs?
- Are there any known factors that could lead to ECCs?
7. Lack of Customer Support Details
Premium leased line services should include 24/7 UK-based support. If your quote doesn’t mention this or only offers business-hours support, that’s a risk.
Key details to check:
- Is support available 24/7?
- UK-based or outsourced?
- Is a dedicated account manager included?
