Constructionline is a pre-qualification database: you pay an annual fee, reported at around £249 for Bronze, £499 for Gold and £2,299 for Platinum by turnover band, to be verified and visible to buyers who run tenders. SiteLens watches the planning register and surfaces live projects the day the council publishes them, classified by trade and value, from £0. They are two different jobs, and this page helps you pick.

Constructionline is about visibility and compliance, getting accredited so main contractors and public buyers can shortlist you for tenders. SiteLens is about discovery, finding the actual projects, and the developers behind them, so you can approach them first.
By the time a project reaches a buyer’s Constructionline tender list, it is well advanced. SiteLens alerts you at planning stage, often months before tender, while there is still time to get your product specified or build the relationship. SiteLens also surfaces live public-sector tenders and recent contract awards near your work, so you can see who is buying and who is winning.
Constructionline runs from several hundred to a few thousand pounds a year by turnover band. SiteLens is £29/mo billed annually (£39 monthly), with a free-forever tier, unlimited application views and AI classification on every project.

Many contractors will run both, because they answer different questions. Constructionline keeps you accredited and visible so you can be shortlisted for formal tenders. SiteLens finds the live projects and the developers behind them at planning stage, so you can get in early rather than waiting for a tender to appear. Use Constructionline to be found, and SiteLens to find.
Constructionline pricing is set by your turnover band and membership level. Independent guides report joining fees of around £249 for Bronze, £499 for Gold and £2,299 for Platinum, with an annual renewal from the second year. SiteLens gives unlimited application views on every plan, including free. Pro is £29/mo billed annually, or £39 monthly. Figures are from independent guides as at August 2026.
They do different jobs. Constructionline is a pre-qualification and accreditation database that makes you visible to buyers running tenders. SiteLens finds live projects at planning stage so you can approach them directly. If you want to find work earlier rather than wait to be shortlisted, SiteLens is the better fit, and many firms use both.
Constructionline gets you found, you pay to be accredited and listed so buyers can shortlist you for tenders. SiteLens helps you find, it surfaces new planning applications in the next morning's alert once the council publishes them, classified by trade and value, so you can reach the project and the developer before it becomes a tender.
If your goal is to be pre-qualified and compliant so public and private buyers can shortlist you for formal tenders, Constructionline is purpose-built for exactly that. Its Bronze, Silver, Gold and Platinum tiers verify your accreditations and SSIP status and put you in front of a large network of buyers, which SiteLens does not do, it provides no accreditation or PQQ at all.
SiteLens is the complementary tool: it finds the projects themselves, early, so you can approach them before they reach a tender list. If formal tender visibility and compliance are what you need, Constructionline earns its place, and the two work well together.
