2025 UK Gas Safety Regulation Changes: What Homeowners & Landlords Need to Know
As of 2025, new gas safety regulations have come into effect across the UK — impacting boiler installations, landlord responsibilities, and gas safety recordkeeping. Whether you're a homeowner, landlord, or tenant, staying up to date with these changes is vital for compliance, safety, and energy efficiency.
At Gas-Go Heating, we’ve broken down the most important updates and what they mean for you.
🔥 What's Changing in 2025? A Quick Overview
| Area | 2025 Regulation Update |
|---|---|
| Boiler Installations | Only hydrogen-ready and 92%+ efficient boilers can be installed |
| Smart Heating Controls | Advanced heating controls now mandatory for combi boiler installs |
| Landlord Gas Safety Checks | Digital-only Gas Safety Records and stricter delivery deadlines |
| Gas Safety Certificate Rules | Tenants must receive digital certificates within 28 days of the inspection |
| Green Gas Integration | Rules updated to support hydrogen and biomethane in the national gas grid |
1. 💨 Hydrogen-Ready & Energy-Efficient Boilers Now Required
From January 2025, all newly installed gas boilers in the UK must be:
- Hydrogen-ready (able to run on up to 20% hydrogen mix)
- Minimum 92% energy efficient, according to the Energy-related Products (ErP) directive
This move supports the UK’s Net Zero 2050 goals and future-proofs your heating system for greener fuels.
➡️ What it means for homeowners:
When replacing a boiler, ensure your installer fits a hydrogen-ready model that meets modern energy standards.
➡️ What it means for landlords:
All new boilers in rental properties must comply or risk non-compliance with Housing Health and Safety Rating System (HHSRS) standards.
2. 📱 Smart Heating Controls Now Mandatory
New boiler installs — particularly combi boilers — must include:
- Time and temperature controls plus
- At least one advanced feature, such as:
- Weather compensation
- Load compensation
- Smart thermostats
- Flue Gas Heat Recovery Systems (FGHRS)
This is part of the Boiler Plus scheme, designed to reduce gas usage and improve home heating efficiency.
3. 🧾 Digital-Only Gas Safety Records (CP12)
From April 2025, all Gas Safety Certificates must be issued and stored digitally. Paper records are no longer acceptable.
✅ Digital CP12s must be:
- Sent to tenants within 28 days
- Provided before any new tenancy begins
- Stored by landlords for at least 2 years (preferably longer)
➡️ Tip: Gas-Go Heating can issue digital gas certificates directly via email or SMS for full compliance.
4. 🛠️ Annual Gas Safety Checks: MOT-Style Flexibility Continues
While the annual requirement remains unchanged, landlords can still:
- Conduct inspections up to 2 months before the due date
- Maintain a continuous 12-month compliance cycle
This flexibility was first introduced in 2018 and continues into 2025.
⚠️ Non-compliance can result in:
- Unlimited fines
- Up to 6 months imprisonment
- Inability to serve valid Section 21 eviction notices
5. 🌱 UK Prepares for Hydrogen & Green Gas Integration
Though the switchover to 100% hydrogen heating is still years away, the UK is laying the groundwork. New 2025 rules support:
- Biomethane producers accessing the gas grid
- Hydrogen blending trials to test national compatibility
This means your boiler and pipework may need future upgrades — which is why hydrogen-ready appliances are now essential.

Hydrogen-ready boiler mandate in 2025
There’s a strong industry push, backed by boiler manufacturers and gas grid operators, for all new boilers to be “hydrogen-ready” from 2025.
Government proposals suggest readiness for up to 20% hydrogen blends, as part of a broader path toward greener heating.
Minimum 92% efficiency and Boiler Plus controls
UK’s Boiler Plus regulations, in effect since April 2018, require a minimum 92% ErP efficiency and mandate both time-and-temperature controls, plus an advanced feature (e.g., smart or weather-compensating thermostats) for combi boilers.
Digital-only Gas Safety Records (CP12) from April 2025
Landlords are transitioning toward digital CP12 certification and record-keeping, with authorities strongly encouraging—and in some cases mandating—electronic formats.
Annual gas safety checks with “MOT-style” flexibility
The 2018 amendment to the Gas Safety Regulations allows up to two months early inspection without reducing the 12-month cycle.
Distribution of CP12 within 28 days
Landlords must provide tenants with the gas safety certificate within 28 days of inspection – a longstanding legal requirement.
🔍 Points to Note
Hydrogen timeline uncertainties:
Though strong momentum exists around hydrogen-ready boilers, the UK government’s final regulations and rollout schedule are still developing.
No outright ban on boilers yet:
While low-carbon heating solutions are being promoted, there is currently no outright ban on gas boilers beyond newbuild standards (which favour heat pumps/hydrogen) .
✅ Conclusion
Overall, the blog's content is well-founded and reflects the current UK gas safety and efficiency landscape. However, note that:
Full legal implementation of hydrogen-ready mandates and exact dates may still be in flux.
Some proposed changes remain under consultation and may evolve in 2025.
