Quick Answer
The Building Safety Act 2022 affects every construction trade in England, not just high-rise developers. Budget for BSR application fees (from £113 per application), competency training (£25 to £3,000+ depending on trade), golden thread software (£40 to £200/month), and increased building control charges (up 4.8% in 2026). The Building Safety Levy launches 1 October 2026, adding £12.70 to £100.35 per square metre on residential developments of 10+ homes. Non-compliance penalties are now unlimited fines and up to two years in prison, with no time limit on prosecution.

What the Building Safety Act actually changes for tradespeople
The Building Safety Act 2022 is the biggest change to construction regulation since the Building Act 1984. It was born from the Grenfell Tower fire and the Hackitt Review, and its reach goes far beyond cladding on tower blocks.
If you work on any building subject to Building Regulations in England, this Act affects you. That includes domestic extensions, loft conversions, and refurbishments. The days of treating Building Regs as a formality are over.
Three new duty holder roles now apply to all building work under Building Regulations. The Client must appoint competent people. The Principal Designer oversees design compliance. The Principal Contractor plans, manages, and monitors the construction phase. These mirror CDM roles but are broader in scope, and ignorance is no defence.
This applies to domestic work too
Duty holder responsibilities extend to ALL building work subject to Building Regulations, including domestic extensions, loft conversions, and garage conversions. For domestic projects where the client lacks competence, their duties transfer to the design and building professionals they appoint. If you are the only professional on a domestic job, the duty holder responsibilities likely fall on you.
Higher-risk buildings (HRBs) get the most scrutiny. Currently, an HRB is any residential building at least 18 metres tall or with 7+ storeys containing two or more residential units. The government is expanding this to include buildings between 11 and 18 metres, which brings a much larger number of mid-rise projects into scope.
For tradespeople working on these buildings, every piece of work must be documented, every change logged, and every product traceable. It costs time and money. This guide breaks down exactly where those costs land. If you are navigating building control notifications for your projects, the BSA adds new layers on top of the existing process.
Building Safety Regulator fees and charges
The Building Safety Regulator (BSR) transitioned to an independent body under MHCLG on 27 January 2026. It now charges fees for every interaction, and those fees are not cheap.
BSR application charges (2025-2026 scheme)
| Application type | Fixed fee | Hourly rate |
|---|---|---|
| Building control approval (HRB) | £189 | £151/hr |
| Change control application | £189 | £151/hr |
| Completion certificate | £227 | £151/hr |
| Regularisation certificate | £151 | £151/hr |
| HRB registration | £251 | £151/hr |
| Building assessment certificate | £302 | £151/hr |
| Notifiable change application | £113 | £151/hr |
Professional registration charges
Building Inspectors pay £336 for initial four-year registration, then £216 per year for maintenance. Building Control Approvers face much steeper fees: £4,494 for initial five-year registration and £3,439 per year for maintenance in years two to five. Assessment work is charged at £130 per hour.
These costs ultimately flow down to project budgets. When your building control provider pays more to operate, those charges land on the project, and eventually on your quotes.
Gateway system costs at each stage
The gateway system creates three hard stops in the construction process for higher-risk buildings. You cannot proceed past each gate without BSR approval, and each gate costs money and time.
Gateway 1: planning permission
A fire statement from the client is required, and HSE acts as a statutory consultee. No additional BSR fee beyond normal planning costs, but the fire statement preparation adds consultant fees. Budget £500 to £2,000 for specialist fire safety input at planning stage.
Gateway 2: before building work begins
This is the big one. The BSR application costs £189 plus £151 per hour for review time. Full plans and Building Regulations compliance evidence must be submitted. Construction cannot start until approval is granted. This is not a rubber stamp; the BSR has rejected applications and sent them back for rework.
Every design change during construction must be categorised as "major" or "notifiable". A notifiable change costs £113 plus hourly review. A major change costs £189 plus hourly review. On a typical HRB project, expect three to five change applications during construction.
Realistic Gateway 2 budget for an HRB project
Application fee: £189. Review time (estimated 10-20 hours): £1,510 to £3,020. Three change applications: £339 to £567. Total Gateway 2 cost: £2,038 to £3,776 per project, before you factor in your own time preparing documentation.
Gateway 3: before occupation
The completion certificate application costs £227 plus £151 per hour for review. Golden thread documentation must be handed over. The building cannot be legally occupied until the certificate is issued. HRB registration adds another £251.
The government's own economic impact assessment estimated the construction industry faces a rise in costs of £385.5 million over 15 years from changes to the building control regime for HRBs alone. That figure does not include the knock-on costs for smaller projects.
Training and competency requirements
Under the BSA, everyone carrying out design or building work must demonstrate competence through four pillars: Skills, Knowledge, Experience, and Behaviours (SKEB). Being good at your trade is no longer enough on its own. You must also understand the safety implications of your work and demonstrate that understanding.
What training costs look like
| Training type | Typical cost | Duration |
|---|---|---|
| CIOB BSA Awareness eLearning | £25 | 90 minutes |
| CSCS card renewal | £58.50 | Card + HS&E test |
| NVQ Level 2 Passive Fire Protection | £950 | Varies |
| NVQ Level 3 Electrical Installation | £1,500 to £3,000+ | Varies by provider |
| BIM/golden thread software training | £200 to £1,000+ | 1 to 5 days |
The CITB Skills & Training Fund closed on 30 September 2025. From October 2025, training funding is only available through Employer Networks, which typically cover up to 70% of costs, down from 100%. That means small firms now shoulder 30% or more of every training bill directly.
Electrical contractors face a specific deadline. New Electrotechnical Assessment Specification (EAS) qualification requirements come into force in October 2026. Firms must find both time and money to upskill their workforce before then. If you are dealing with other compliance costs at the same time, such as the MTD Phase 2 penalties starting April 2026, the financial pressure stacks up quickly.
Only 39% of small firms are aware of their BSA obligations
A BESA survey found that just 39% of micro and small construction firms are aware of the Building Safety Act and its consequences. The majority described the legislation as "overwhelming and daunting". If you are reading this article, you are already ahead of most of your competitors.
Golden thread: digital record-keeping costs
The golden thread is the requirement to maintain complete, accurate, and accessible building safety information throughout a building's lifecycle. For HRBs, this is mandatory from design through construction to occupation and beyond.
In practice, this means every product installed, every inspection completed, and every change made must be digitally recorded and traceable. The days of scribbling notes on a clipboard and filing them in a drawer are ending.
Software costs for small firms
Purpose-built golden thread platforms like Operance, MosaicGT, and BlockPro typically charge subscription fees. Construction management software ranges from £44 to £2,850 per month depending on features and user count. BIM software (Autodesk Revit, ArchiCAD) costs £120 to £1,000+ per month per user.
For a sole trader or small firm, a realistic budget is £40 to £200 per month for a platform that handles digital records, photo documentation, and compliance certificates. That is £480 to £2,400 per year before you factor in the time spent learning and using it.
Start simple
You do not need enterprise BIM software for most domestic and small commercial work. A combination of structured photo documentation, digital certificates, and a basic project management tool can meet golden thread requirements. The strongest approaches combine digital records with physical proof: photographs, test certificates, and inspection logs.
The Building Safety Levy from October 2026
The Building Safety Levy launches on 1 October 2026. It aims to raise approximately £3.4 billion over 10 years to fund remediation of unsafe cladding and building defects across England.
Who pays
Developers of new residential schemes of 10 or more dwellings in England. Social housing, supported housing, and agricultural buildings are exempt. While developers pay the levy directly, the costs filter down through the supply chain to subcontractors and tradespeople through tighter project budgets and pricing pressure.
How much it costs
Rates vary by local authority, with a 50% discount for brownfield (previously developed) land where 75%+ of the site qualifies.
| Local authority | Standard rate/sqm | Brownfield rate/sqm |
|---|---|---|
| Kensington & Chelsea | £100.35 | £50.17 |
| Westminster | £98.01 | £49.01 |
| Camden | £87.12 | £43.56 |
| Cambridge | £50.87 | £25.44 |
| Birmingham | £29.23 | £14.62 |
| Manchester | £28.44 | £14.22 |
| County Durham (lowest) | £12.70 | £6.35 |
The Home Builders Federation has called it "a nakedly anti-development new tax on new homes" and warned it adds approximately £3,000 per plot on average. HBF CEO Neil Jefferson said the levy will "add thousands of pounds to the cost of new homes, threatening the viability of sites across swathes of the country."
For tradespeople, this means tighter project budgets on new-build residential work. Developers will look to cut costs elsewhere, and subcontractor rates will come under pressure. If you are already reviewing your pricing model, factor the levy's knock-on effect into your rate calculations.
Penalties for non-compliance
The penalty regime under the BSA is dramatically harsher than the old system. Previously, breaching Building Regulations was a summary-only offence with a maximum £5,000 fine plus £50 per day. Those days are gone.
What you face for getting it wrong
- Breach of Building Regulations: unlimited fine and/or up to 2 years imprisonment
- Failure to comply with compliance notices: unlimited fine and/or up to 2 years imprisonment
- Failure to comply with stop notices: unlimited fine and/or up to 2 years imprisonment
- New Homes Warranty non-compliance: up to £10,000 or 10% of the building's value
- Daily fines for continuing non-compliance after conviction
Personal liability for directors and managers
Directors, managers, and company secretaries can be personally liable if a breach is committed with their "consent or connivance" or is "attributable to any neglect" on their part. This is not just a company risk. It is a personal one.
The enforcement timeline has also changed. The time limit for enforcement action increased to 10 years from completion of works. For Building Regulations contraventions, there is now no time limit on prosecution. Work you did five years ago could come back to bite you if it does not meet the standards.
This is a similar pattern to the CIS penalties regime, where small mistakes can snowball into significant financial consequences. The lesson is the same: get the paperwork right the first time.
Insurance implications and cost changes
The BSA has shifted the insurance landscape for construction professionals. The good news is that the Professional Indemnity Insurance (PII) market is broadly improving for SMEs with clean claims records, with double-digit rate reductions available.
The bad news is that the Act has widened liability exposure in several ways.
Key insurance impacts
- Extended limitation periods: the Defective Premises Act now allows claims for 15 years retrospectively and 30 years prospectively. Historical projects that were previously statute-barred now create new liability exposure.
- Wider duty holder liability: Principal Designers and Principal Contractors must check the work of all project members, increasing "duty to warn" liability.
- Higher deductibles: increases of 6-9% on large projects in 2025.
- New Homes Warranty: now mandatory for new homes and conversions, with penalties for non-compliance.
Budget for a 5-15% increase in PII premiums if you are taking on Principal Designer or Principal Contractor roles. Shop around; the market is competitive for firms with clean records, but you need to disclose the BSA roles you are taking on.

The second staircase requirement for new residential buildings of 18m+ has a deadline of 30 September 2026. Adding a second staircase increases cost per flat by approximately £22,500 and reduces saleable floor area by about 7%. Total build cost increases range from 6-13% due to new pressurised core requirements. For context on how fire safety requirements interact with the BSA, see our fire safety regulations guide.
Frequently asked questions
Yes. The duty holder requirements apply to ALL building work subject to Building Regulations in England, not just high-rise buildings. For domestic projects, the client duties typically transfer to the design and building professionals appointed to the project. If you are the sole contractor on a domestic extension, you are likely the Principal Contractor by default.
The Building Safety Act 2022 primarily applies to England. Scotland has its own Building (Scotland) Act 2003. Wales follows some provisions but has its own regulatory framework. Northern Ireland has separate building regulations. If you work across borders, check the specific requirements for each jurisdiction.
Currently, a higher-risk building (HRB) is any residential building in England that is at least 18 metres tall or has at least 7 storeys, containing 2 or more residential units. The government plans to expand this definition to include buildings between 11 and 18 metres, which will significantly increase the number of projects in scope.
Yes. Directors, managers, secretaries, and similar officers of a body corporate can be personally liable if a breach is committed with their "consent or connivance" or is "attributable to any neglect" on their part. Personal liability means unlimited fines and up to 2 years imprisonment, regardless of limited company status.
As a sole trader doing domestic and small commercial work, budget approximately £1,500 to £3,500 per year. This breaks down roughly as: BSA awareness training £25 to £200, CSCS card renewal £58.50, golden thread software £480 to £1,200 per year, additional PII premium £200 to £500, and admin time for documentation at around £500 to £1,500 in lost productive hours. Use the calculator above to get a more specific estimate for your situation.
The golden thread is the requirement to maintain complete, accurate, and accessible building safety information throughout a building's lifecycle. It is mandatory for higher-risk buildings. For domestic work, while not strictly required to the same standard, maintaining good records of products used, inspections, and compliance certificates is strongly recommended. It protects you against future claims and demonstrates competence under the BSA duty holder requirements.
