The Building Safety Levy (BSL) has arrived with a clear message for local authorities: this is your responsibility now.
You’re the ones receiving applications, verifying GIA measurements, calculating fees, collecting payments and filing returns to MHCLG every quarter. And you’ll be doing all of this on top of the day-to-day pressures your building control team is already carrying.
Managing your BSL obligations won’t sit neatly in one place within your local authority. That’s what makes it so challenging. While it will be centred in building control, it may also pull in finance, development control and other teams across your organisation. As such, getting everyone working from the same process, using the same data on day one without a dedicated system isn’t a given.
For many local authorities, it presents a genuine coordination challenge, one that’s easy to underestimate. This blog explains the requirements for managing BSL compliance across the full development lifecycle.
What the BSL requires local authorities to do
The Building Safety Levy is a Government charge on new residential developments in England. It will apply from 1 October 2026. However, it’s worth being clear about what the BSL process will involve in practice when it lands, because the scope of it is broader than it might first appear.
Your team will need to receive BSL-specific applications and check that they contain the right information.
You’ll then need to verify the Gross Internal Area (GIA) measurements from the floor plans submitted, either at site master level or for individual plots. That verification must be accurate, because GIA is the foundation of the fee calculation. Get it wrong, and you’ve got a dispute to manage.
Once GIA is confirmed, you’ll need to apply the correct levy fee schedule and issue the applicant with a fee calculation. Then you’ll need to request payment, track whether it’s been received, and chase any outstanding balances. At the end of each quarter, you’ll need to pull all of that together and file your return with MHCLG in the required format.
Each of these steps creates a real piece of work. None of them will happen automatically, and none of them are optional. For building control teams that are already stretched, as most are, this represents a significant new administrative burden. The teams most likely to struggle won’t be those who lack competence. They’ll be the ones who don’t have the systems to support the process reliably.
The challenge of managing this end-to-end
The BSL process doesn’t start and stop at any one point. It runs through the whole lifecycle of a relevant application, from the initial submission, through checking and fee calculation, to payment collection and quarterly reporting. If your process is fragmented at any stage, the problems will compound.
If your local authority is thinking about trying to manage this through a combination of your existing but unconnected back-office tools, you could be introducing unnecessary risk into your processes, including:
- Submissions arriving in different formats, that need to be manually translated into usable data.
- GIA calculations done outside the system, which means they’re easier to get wrong and harder to audit.
- Fee schedules being applied manually, which opens the door to inconsistency.
- Inconsistent payment chasing, which will make it difficult to see what’s been received and what hasn’t at any given moment.
- Quarterly returns that require someone to pull everything together from scratch, with no single source of structured data to draw on.
These aren’t hypothetical risks. They’re the potential consequences of trying to manage a joined-up process with disjointed tools, systems and teams.
How our BSL module handles the process from start to finish
Our dedicated Building Safety Levy module is built around the full lifecycle of a BSL application. Rather than addressing the individual steps in isolation, it connects all of them in one place.
Your applicants submit their applications through Submit-a-Plan, the same portal they already use for building control. This process is configured to your local authority’s specific BSL requirements, so you receive the right information in the right format from the outset. There’s no need to chase incomplete submissions or convert emails into usable data. The system automates all this for you, so that when the data comes in, it’s ready to work with.
From there, your team can view and measure floor plans within the system. The built-in plan measurement tools let you calculate and combine individual plots and floor areas without switching to a separate application or working from a printout. Every measurement is recorded in the system, so your GIA figures are traceable and auditable from the start.
Once your team has verified the combined GIA, the system automatically applies your BSL fee schedule. You get a clear, documented fee calculation that you can check, confirm and send to the applicant, with a full audit trail behind every figure.
The system also integrates with your authority’s existing payment infrastructure, so there’s no new system to set up. Once your fees are issued, the platform tracks what’s been requested, what’s been received and what still needs chasing. You and your finance team can see exactly where things stand at any point, without having to ask building control for a status update.
Only once full payment has been collected will the system allow you to issue a certificate of completion to say the job’s done and the client has paid their Levy in full.
And when your quarterly MHCLG return is due, your data is already structured and ready. The reporting function will pull together all the figures you need, in the format MHCLG requires.
Why an integrated BSL software solution makes the difference
There are a few alternative tools available that handle parts of the BSL process.
It’s much harder to find a solution where every part is connected and where data flows from submission through to reporting without needing to be rekeyed, rechecked or reconciled across different systems.
Our BSL module achieves this because it’s built on top of Submit-a-Plan and DataSpace Live, two proven platforms that are already in daily use by local authority building control teams across the UK. That integration forms the foundation of the process. The GIA measurements taken in the system feed directly into the fee calculations, which, in turn, feed into the payment records. These then feed into your quarterly returns. You need to enter the information only once, and it carries through the whole process.
That also means every step leaves a trace. Every calculation, payment request and reporting figure is logged and auditable. If MHCLG has questions, you have the evidence to back up every decision you’ve made.
No other provider currently combines a client-facing submission portal, integrated plan checking and back-office compliance tools in a single BSL solution. It streamlines how you manage your BSL compliance and reporting obligations across multiple departments and teams.
Getting your BSL processes right from the start
The Building Safety Levy (England) Regulations 2025 come into force on 1 October 2026, and the levy will start being applied from that date. It doesn’t leave much room to find your feet.
Your first return will come around quickly, and if your process isn’t reliable by then, you’ll be under pressure to fix it while also meeting your obligations. So, getting your systems in order is before that pressure arrives is essential.
Our BSL module is designed to support the full process from day one, so that by the time your first quarterly return is due, you’ll be working from a system that was built to do the job rather than scrambling data together.
