How to Calculate Win Rate for UK Public Sector Bids
Win rate is the percentage of bids you submit that result in contract awards — a core metric for any government sales team. But calculating it correctly matters: should you include no-bids, framework call-offs, or mini-competitions? How do you benchmark against industry norms? This guide explains how UK suppliers should measure, interpret and act on public sector win rates in 2026.
Put this into practice
Accurate win rates need complete pipeline data. TenderLedger helps you track pursuits from opportunity to award with the detail needed for meaningful metrics.
Why this matters commercially
Win rate reveals whether your qualification process selects winnable opportunities.
Tracking by segment exposes where your strengths and weaknesses lie.
Benchmarking against industry norms prevents complacency or unfounded panic.
Win rate trends over time show whether improvements are working.
Commercial teams use win rates to justify bid resource investments.
How suppliers usually do this manually
Counting only remembered wins without systematic bid tracking.
Including no-bids in the denominator, artificially lowering rates.
One blended rate across £50k council quotes and £10M frameworks.
No distinction between open competitions and framework call-offs.
Ignoring losses by never recording unsuccessful submissions.
Signals worth tracking
CRM or pipeline tool with status tracking through to award/loss.
Consistent definitions of what counts as a 'submitted bid'.
Regular reporting cadence (quarterly minimum).
Segmentation fields: sector, buyer tier, contract value band.
Loss reasons captured systematically, not anecdotally.
Common mistakes to avoid
Celebrating high win rates that mask under-bidding or low ambition.
Comparing framework call-off rates to open-competition benchmarks.
Blaming 'the market' for low rates without examining qualification.
Changing definitions mid-year to make trends look better.
Using win rate alone without considering bid cost and contract value.
How TenderLedger supports this workflow
Pursuit tracking from opportunity through submission to award/loss.
Award data to verify outcomes and capture competitor wins.
Qualification workflows that reduce wasted bids before submission.
Reporting views segmented by buyer, sector and value band.
Competitor win patterns to contextualise your own performance.
Example in practice
A facilities firm discovered their overall 22% win rate masked a 45% rate on NHS contracts and 8% on MoD — they reallocated BD focus accordingly.
An IT supplier's 50% win rate looked strong until analysis showed they only pursued uncompetitive small deals; raising ambition initially dropped win rate but increased revenue.
Practical workflow
Define 'submitted bid' clearly: exclude no-bids, include all formal submissions.
Track framework and open-competition win rates separately.
Segment by contract value (e.g. <£100k, £100k–£1M, >£1M).
Review quarterly with trend analysis, not just point-in-time snapshots.
Pair win rate with bid cost and average deal size for ROI insight.

About this data
TenderLedger aggregates UK public procurement signals from official sources including Find a Tender (FTS) and Contracts Finder. We combine notice metadata, contracting authorities, and award history into a consistent opportunity view for suppliers.
For these pages, we structure insights using procurement patterns commonly visible in award notices, framework call-offs, and DPS activity. The examples below are designed to mirror how supplier teams qualify bids day-to-day.

FAQs
What is a good public sector win rate?
25–35% is typical for experienced UK government suppliers on competitive tenders. Below 15% suggests qualification problems; above 50% may indicate under-bidding.
Should I include framework call-offs in my win rate?
Track them separately. Call-off win rates are typically higher than open competitions and mixing them distorts your benchmark.
How do I count joint ventures or consortium bids?
If you submitted as part of the winning team, count it as a win. Be consistent in your definition across all bids.
What about bids we withdrew?
Exclude withdrawn bids from the denominator — they were qualification decisions, not losses.
How often should I calculate win rate?
Quarterly is standard, with rolling 12-month views for trend analysis. Monthly can be too noisy for low-volume bidders.
