# Working across the England–Wales border
This guide walks you through what actually changes when you take a job over the England–Wales border, building regs, planning, waste, environmental stuff, and notifications. It's written for builders, plumbers and sparks working out of places like Cheshire, Shropshire, Herefordshire, Glos and Bristol, and for Welsh outfits nipping over into England.
Quick rule of thumb: one registration covers you across the border (Gas Safe, NICEIC, NAPIT, waste carrier), but the job must be designed and signed off to the rules of the country the site is in.
1. What "devolved" actually means for you
England and Wales share a lot of the same legal skeleton, but Wales now runs its own guidance and systems on top of it. For you that means:
- Same core laws in the background · Building Regulations 2010, Town and Country Planning Act 1990, Environmental Permitting Regulations 2016, Waste (England and Wales) Regulations 2011.
- Different rulebooks and people: Wales has its own Approved Documents, its own planning policy (PPW + TANs), and its own environmental regulator (Natural Resources Wales) instead of the Environment Agency.
- Your trade registrations (Gas Safe, NICEIC, NAPIT) still work both sides, but you must follow the local country's technical rules on the job.
- If the site postcode is in Wales, assume Welsh guidance and Welsh bodies apply. If it's in England, work to English documents and English bodies.
Tip for new starters First thing on any enquiry, look up the postcode, confirm "England or Wales?", and write that on your job sheet. It decides whose rulebook you follow.
2. Building Regulations, England vs Wales
Same SI, different guidance
Both countries still use the Building Regulations 2010 statutory instrument, but the Approved Documents that explain how to comply are now separate.
- England · uses the merged Approved Documents published by UK Government for England only.
- Wales · publishes its own Approved Documents and circulars through Welsh Ministers, with different update timings and sometimes tighter standards.
As of 2026, Wales is also bringing in extra building safety changes under its own regulations made off the back of the Building Safety Act 2022, with separate Welsh regulations coming into force from July 2026.
Practical differences you'll see
| Thing (2026) | England job | Wales job | What you do differently |
|---|---|---|---|
| Which Approved Docs | England-branded Approved Documents, including the merged 2024 editions | Welsh-branded Approved Documents (download from Welsh Government / LABC Wales) | Don't wave an England PDF at a Welsh BCO |
| Updates and timing | England often implements changes first or on different dates (e.g. uplifted energy standards) | Wales takes its own path, different commencement dates and sometimes stronger energy/overheating targets | On the border, check dates for each country before pricing |
| Building control language | "Applications for building control approval" and the Building Safety Regulator for higher-risk buildings | Wales is rolling in its own building safety amendments; terminology and process are being aligned but via Welsh regulations | If you work on bigger jobs, don't reuse England boilerplate, check the Welsh circulars |
| Building control providers | LABC or registered building control approvers under English rules | LABC Wales or Welsh-registered building control approvers, under Welsh regulations | Make sure your chosen BCO is authorised for the right country |
Example: small extension in Oswestry vs over the line in Welshpool:
Structure and fire: broadly similar in both, but you must design and quote to the Welsh U-values and any local Welsh tweaks if the house is in Welshpool. The client might show you an England-based SAP calc or spec, you still have to check it against the latest Welsh Approved Document L.
Tip for new starters For any Welsh job, download the Welsh versions of the specific Approved Documents (A, B, L, O, P, etc.) and stick them in a "Wales" folder on your phone or laptop, don't rely on England PDFs.
3. Planning, TANs vs PPG / NPPF
Different planning rulebooks
Both countries still rely on the Town and Country Planning Act 1990, but the policy and guidance under it is completely different.
- England: uses National Planning Policy Framework (NPPF) plus Planning Practice Guidance (PPG).
- Wales: uses Planning Policy Wales (PPW) plus Technical Advice Notes (TANs) and other Welsh circulars.
The TANs cover things like design, housing, transport, minerals, and more, and they're written to line up with Wales-specific priorities such as the Well-being of Future Generations (Wales) Act 2015.
What this means on your jobs
- Permitted development: what's PD in an English village outside Chester might need full planning consent just across the border in Flintshire because the Welsh PD rights and policy tests are different.
- Design and layout: Welsh planners lean heavily on PPW/TANs, which can push different design choices, density, active travel and sustainability requirements than NPPF/PPG do in England.
- Paperwork / portals: English councils usually feed through the Planning Portal or similar; Welsh LPAs run their own systems and Welsh forms.
Example: small developer based in Herefordshire:
- Site in Hereford: you check NPPF/PPG and local plan; PD rules are England-style; highway and drainage expectations match English guidance.
- Site just over the Wye in Monmouthshire: you work off PPW and TANs; more weight goes on long-term sustainability and well-being; some details (for example, SuDS, travel plans) may be handled differently and cost more time or money.
Tip for new starters If you offer "we'll sort your planning" to clients, bookmark PPW/TANs for Welsh jobs and NPPF/PPG for English ones. Never quote "it's PD" without checking the right country's rules.
4. Waste carrier licence, do you need a separate Welsh one?
The Waste (England and Wales) Regulations 2011 set up a system where you must register as a waste carrier, broker or dealer if you move waste as part of your work.
- If your business is based in England, you register with the Environment Agency.
- If your business is based in Wales, you register with Natural Resources Wales (NRW).
- You do not normally need two separate registrations just because you cross the border · one registration in the country where you're based covers you for carrying waste anywhere in England and Wales.
| Situation (2026) | What you need | Who you deal with |
|---|---|---|
| Shropshire builder carrying own rubble to tip in Shrewsbury and Wrexham | Lower or upper tier waste carrier registration, depending on whether you carry others' waste | Register with Environment Agency; your registration is valid when you tip in Wales |
| Wrexham plumbing firm taking old boilers to Chester | Waste carrier registration with NRW; same registration is valid in England | Register with NRW |
| Using a skip firm across the border | You don't register, but you must check the skip company is registered with EA or NRW | Use EA/NRW online registers to check |
Tip for new starters Base in England = register once with the Environment Agency. Base in Wales = register once with NRW. Keep your number on your quotes and waste transfer notes so you can prove you're legit on both sides.
5. Competent person schemes, NICEIC, NAPIT, Gas Safe
Good news: the big schemes operate across England and Wales, so you don't need separate memberships.
- Gas Safe Register is the official gas registration body for the whole UK, including Wales. If you're Gas Safe in England, you're Gas Safe in Wales as long as your categories match the work.
- Part P electrical work: schemes like NICEIC and NAPIT cover domestic electrical work in both England and Wales under the same Part P framework. Full-scope Part P electricians are listed on a single register and can notify work via their scheme regardless of which side of the border the job is on.
What changes across the border is not the registration, but the technical standard you're working to:
- On a Welsh job, you follow Welsh building regs (including any Welsh-specific Part P guidance), even though you use the same NICEIC/NAPIT/Gas Safe login to notify.
- Local building control is Welsh, so if they query your cert, they'll use Welsh guidance and Welsh circulars.
Example: A Bristol spark, registered with NICEIC, rewires a cottage near Chepstow. They can self-certify as usual, but must make sure the design matches the current Welsh Approved Document P and any local Welsh guidance, and they notify that job as a Welsh LPA through NICEIC.
Tip for new starters Check your scheme profile shows the right trading address and working areas so Welsh or English building control can find your notifications without hassle.
6. Environmental rules, NRW vs Environment Agency
The Environmental Permitting (England and Wales) Regulations 2016 apply in both countries, but they're enforced by different regulators:
- In England, the Environment Agency handles environmental permits, pollution, some flood risk, and enforcement.
- In Wales, Natural Resources Wales (NRW) does the same job, plus a wider brief over Welsh natural resources.
What this means for site work:
- Any crushing, screening, fixed plant, or specific discharges may need an EA permit in England or an NRW permit in Wales.
- Pollution incidents (diesel spill, silt in a stream, concrete washout) are reported to EA in England and to NRW in Wales. Both can investigate and prosecute.
- NRW's guidance, consultations and permitting processes are Welsh-specific · they consult publicly on certain permits and expect early engagement.
Example: groundworks firm based in Gloucester:
- Job on the English side of the Severn: flood risk activity permits and pollution control are with the Environment Agency.
- Job on the Welsh side near Newport: very similar rules in theory, but all the forms, guidance notes and phone numbers are through NRW, and some expectations on habitat and consultation may be different and take longer.
Tip for new starters Any time you're near a river, wetland or floodplain, find out early whether the regulator is EA (England) or NRW (Wales), then use their website for permits and pollution guidance. Don't guess.
7. Building Control and LABC, who you actually deal with
Local authority building control is delivered by councils through Local Authority Building Control (LABC) bodies in both England and Wales.
- The basic job · plan check, inspections, completion certificates · is similar either side.
- The rules they apply (Approved Documents, safety rules, terminology) are now diverging, especially in Wales as its building safety regime rolls out.
- You also now have the concept of registered building control approvers under the building safety reforms, but the details differ between England and Wales, with Wales bringing in its own regulations for registered building control approvers and their operation.
On a cross-border project:
- If the physical building is in Wales, you must use a Welsh local authority building control team or a building control approver registered to work in Wales, and you work to Welsh guidance.
- If the building is in England, you use English LABC or an approver authorised for England and follow English guidance.
Tip for new starters On every job, make sure the building control body named in the paperwork is actually authorised for that country. If a main contractor has picked the wrong side, raise it early before inspections start.
What to do next
- Make two simple checklists · "England site" and "Wales site" · covering: which Approved Documents to use, which planning policy set you're checking (PPG/NPPF vs PPW/TANs), whether EA or NRW are involved, and which building control body is appointed.
- If you're not already on the waste carrier register in the country where your business is based, get registered online before hauling any more rubble, boilers or spoil.
- Log in to your Gas Safe / NICEIC / NAPIT accounts and confirm your contact details and working areas are up to date so Welsh and English authorities can see your notifications.
- For any job near rivers, floodplains or sensitive land on the border, speak to the main contractor or client early about EA/NRW permits and conditions, and get copies of approvals before you start groundworks.
