When Each Option Makes Sense
Choose a Bid Consultant When:
- You submit fewer than 20 tenders per year
- You need specialist sector expertise you lack internally
- You face urgent deadlines with no internal capacity
- You want to test bidding for a new sector or framework
- You need to scale bid output up or down quickly
- Your current in-house win rate is below 50%
- You are bidding for high-value contracts (over £1M)
Choose In-House When:
- You submit 30+ tenders per year consistently
- Your sector requires deep institutional knowledge
- You need daily bid management and coordination
- You have budget for a competitive salary (£55,000+)
- You can provide career development and progression
- You operate in a single, highly specialised sector
- You want someone embedded in your team culture
The Hybrid Approach
Many of our most successful clients combine both. They retain a bid coordinator in-house for day-to-day pipeline management and engage Glaxtons for high-value, complex, or urgent tenders where specialist expertise makes the difference between winning and losing.
