Overcoming new challenges in in the construction and infrastructure sector in 2026 and beyond

Here at Tsaks Consulting, our construction tender writing services are cutting edge. We have our finger on the pulse of procurement changes across the UK and will ensure you score well in critical new criteria. These include:

Social value in construction and infrastructure tenders

Now critical in construction and infrastructure frameworks across the UK and often representing 10-30% of the weighting criteria.

In 2026, when you are putting together a construction or infrastructure proposal or RFP response, measurable and reasonable objectives backed buy evidence are not enough. They used to be. Now you need to address social value throughout your bid, put in the background work, and be innovative in your approach. Our bid writers will work with you to integrate social value as a win-theme throughout your bid. You need to work within the TOMs framework, and comply with and complete any Social Value Portal with a high score.

Accreditation compliance in construction and infrastructure tenders

Whilst most larger construction and infrastructure contractors have CHAS, SafeContractor and/or ISO certifications, many Tier-2, Tier-3 and sub-contractors do not. These are now often a dealbreaker with compliance and certification a pre-requisite. Our team will help you develop the necessary documentation to comply and achieve certification.
