bng2latlong Pricing: Plans, Tiers, and Cost Examples (2026)

Pricing overview

bng2latlong offers a tiered, usage-based pricing model designed for converting British National Grid (BNG) coordinates, UK postcodes, and latitude/longitude pairs. The service includes a free tier for low-volume use and various paid subscriptions to accommodate higher request volumes. The primary metric for billing is the number of API requests made within a monthly cycle. All plans are billed monthly, with no long-term contracts specified on their official pricing page. Users can typically upgrade or downgrade plans based on their anticipated or actual usage. The pricing structure is transparent, detailing the number of requests included per tier and the corresponding monthly fee, aimed at developers and organizations requiring precise UK geospatial data integration.

The API facilitates essential conversions such as converting postcodes to latitude and longitude, BNG coordinates to latitude and longitude, and reverse geocoding from coordinates back to postcodes. These services are crucial for applications in logistics, mapping, and data analysis focused on the United Kingdom. The pricing model ensures that users pay according to their specific operational scale, from individual developers using the free tier up to enterprises requiring millions of requests monthly.

Plans and tiers

bng2latlong structures its offerings into several distinct plans, each tailored for different levels of API consumption. The core difference between plans is the monthly allowance of API requests and the associated cost. All plans include access to the full suite of conversion APIs, covering postcode, BNG, and latitude/longitude transformations.

Each paid plan provides an allocation of requests that reset monthly. Should an application exceed its allocated requests within a monthly billing cycle, bng2latlong's official documentation does not explicitly detail overage charges but implies that users would either need to upgrade their plan or experience rate limiting until the next cycle. For the precise terms regarding exceeding limits, users are advised to review the bng2latlong pricing terms directly.

The Enterprise plan caters to users with extremely high volume requirements or specific integration needs, offering custom quotas and potentially more personalized support options. Such plans typically involve direct consultation with the bng2latlong team to define terms and pricing structure.

Free tier and limits

bng2latlong offers a free tier that permits up to 500 API requests per day. This free access is designed to allow developers to test the API's functionality, integrate it into proofs-of-concept, or support very low-volume applications without incurring costs. The daily limit resets every 24 hours. While the free tier provides access to the same core API functionalities as paid plans, its primary constraint is the request volume, which translates to approximately 15,000 requests per month if consistently utilized daily.

The free tier is suitable for:

• Initial Development and Testing: Developers can integrate and test the API without commitment.
• Personal Projects: Low-traffic personal websites or applications that occasionally require UK geospatial conversions.
• Proof-of-Concept: Validating the utility of postcode or BNG conversions within a new application idea.

Users considering deploying an application with anticipated higher traffic should plan to transition to a paid plan once their daily request volume approaches or consistently exceeds the 500-request threshold to avoid service interruptions. The transition process generally involves signing up for a paid subscription through the bng2latlong user portal.

Real-world cost examples

Understanding the tiered pricing model through practical scenarios can help estimate potential monthly costs:

1. Small E-commerce Site (Local Deliveries):
   • Scenario: An online store processing 500 orders per day, validating delivery postcodes using the Postcode to Lat/Long API once per order.
   • Calculation: 500 requests/day * 30 days/month = 15,000 requests/month.
   • Cost: This volume fits within the free tier's daily limit (500 requests/day). However, if daily volume is variable and sometimes exceeds 500, or for peace of mind, the Starter Plan (£20/month for 1,000,000 requests) would provide ample buffer. For consistent usage at this level, the free tier could suffice if managed carefully to stay within daily limits.
2. Logistics Startup (Route Optimization):
   • Scenario: A logistics company optimizing routes for 2,000 deliveries per day, requiring multiple BNG conversions and reverse geocoding lookups per route, totaling 10,000 API calls daily.
   • Calculation: 10,000 requests/day * 30 days/month = 300,000 requests/month.
   • Cost: The Starter Plan at £20/month, which includes 1,000,000 requests, would cover this usage comfortably. This plan offers significant headroom, making it cost-effective for this volume.
3. Property Portal (Geospatial Search):
   • Scenario: A real estate website with moderate traffic, where users frequently search for properties by postcode or BNG, generating approximately 150,000 API requests per day across various search and mapping features.
   • Calculation: 150,000 requests/day * 30 days/month = 4,500,000 requests/month.
   • Cost: This volume would require the Business Plan at £50/month, which includes 5,000,000 requests. This plan provides the necessary capacity while keeping costs predictable.
4. Government Data Project (Batch Processing):
   • Scenario: A project requiring the conversion of a large dataset of historical UK addresses to BNG coordinates, performed as a batch process once a month, totaling 12,000,000 conversions.
   • Calculation: 12,000,000 requests in a month.
   • Cost: This exceeds the Professional Plan's 10,000,000 limit. The organization would likely need to opt for an Enterprise Plan, which offers custom quotes for volumes exceeding 10,000,000 requests, ensuring they get a tailored solution for their specific high-volume, potentially bursty, needs.

How the pricing compares

When evaluating bng2latlong's pricing, it's beneficial to compare it against other geocoding APIs, particularly those with a focus on UK data or general global coverage. Key competitors and alternatives include Postcodes.io, OpenCage Geocoding API, and Geolocator (UK).

• Postcodes.io: This is a free, open-source UK postcode API. While it offers basic postcode lookup functionality without direct cost, it may lack the dedicated support, SLA guarantees, or advanced BNG conversion features found in commercial offerings like bng2latlong. Its reliance on community contributions means feature development and uptime may vary. Developers often choose Postcodes.io for projects where budget is the primary constraint and dedicated support is not critical. The Postcodes.io documentation outlines its free usage model.
• OpenCage Geocoding API: OpenCage provides a global geocoding service, which includes detailed coverage for the UK. Their pricing model is also usage-based, often starting with a free tier for low volumes (e.g., 2,500 requests/day) and scaling up to paid plans. For example, their small paid plan might offer 50,000 requests/day for a monthly fee. While globally applicable, bng2latlong specializes specifically in UK conversions, including BNG, which might offer more precision or specific features for UK-centric applications. OpenCage's broader scope can mean higher costs if only UK data is needed, compared to a specialized UK provider. Further details can be found on the OpenCage pricing page.
• Geolocator (UK): Similar to bng2latlong, Geolocator focuses on UK specific geocoding services. Their pricing models are structured with free tiers and paid plans based on request volume. Comparisons often come down to specific feature sets, data accuracy, and user experience. Geolocator's pricing might be competitive, with similar tiers for request volumes. Evaluating these would involve checking the Geolocator pricing plans for direct comparison.

bng2latlong's strength lies in its specialized focus on the UK, specifically with robust support for British National Grid conversions, which is not always a core offering for global geocoding services. Its pricing is competitive for UK-centric use cases, particularly for volumes between 1 million and 10 million requests per month, where its tiered plans offer clear value. For projects requiring global coverage beyond the UK, alternatives like OpenCage might be more suitable, despite potentially higher costs for comparable UK-only volumes.

Overall, bng2latlong's pricing strategy aligns with a value proposition centered on UK data accuracy and specialized conversion capabilities. For developers and businesses operating exclusively or primarily within the UK, its plans offer a predictable cost structure for essential geospatial services.
