Council building control vs approved inspector: which should you choose?
For most home projects in England and Wales you can choose who checks your building regulations compliance: your local council's building control team, or a private registered building control approver (formerly called an approved inspector). Both are legitimate, both can issue the final certificate — but they differ on cost, speed and how they work with your builder. Here is how to decide.[1]

- Your two options
- Council or private
- Same legal weight
- Both issue certificates
- The deciding factors
- Cost, speed, project complexity
The choice you have to make
Every project that needs building regulations approval must be checked by one of two bodies. The local authority building control team is run by your council and has covered its area for decades. A registered building control approver is a private company or individual licensed to do the same job — the role used to be called an approved inspector, and many people still use that name.[1]
Whichever you choose, the legal outcome is the same: inspections at key stages and a certificate at the end that solicitors will ask for when you sell. What differs is the experience — fees, response times, how advice is given, and what happens if something goes wrong. If you have not read it yet, start with building control explained: building notice vs full plans for the overall process, then come back here to choose who runs it.
Side by side: council vs private approver
| Council building control | Private approved inspector | |
|---|---|---|
| Fees | Published fee scales, set by each council; broadly similar across a region | Quoted per job; often competitive with the council, sometimes lower on larger projects |
| Availability | Inspection slots can be booked out in busy areas; response times vary by council | Often faster to visit and to respond to queries, especially on larger or commercial-style projects |
| Local knowledge | Deep knowledge of local ground conditions, housing stock and common problems in the area | Varies — national firms cover wide areas; ask how much work they do locally |
| Advice before you apply | Many councils offer pre-application advice, sometimes free or low cost | Usually included in the quoted service — approvers compete on being helpful early |
| Enforcement powers | The council keeps legal enforcement powers whoever you appoint | No enforcement powers — if things go badly wrong, the case can be handed back to the council |
| Switching mid-project | You can move to a private approver before work starts | Once an approver's initial notice is accepted, switching back to the council mid-project is difficult |
| The final document | Completion certificate | Final certificate — solicitors and lenders treat it the same way |
The single biggest practical difference for a homeowner: a private approver works to your project's schedule and competes for your business, while the council is the default with deep local knowledge but fixed capacity. Neither is "stricter" — both apply the same building regulations.[1]
When the council route tends to suit
- Your builder already works with them. An experienced local builder who knows the council inspectors and what they expect can make the whole process smoother — ask your builder which route they prefer and why.
- Tricky local ground or housing conditions. Mining areas, clay subsidence zones, conservation areas with a history of difficult approvals — the council team has usually seen it all before on your street.
- You want pre-application advice. Many councils will comment on drawings before you formally apply, which de-risks a full plans submission.
- Simple, standard projects. For a straightforward extension the fee difference is often small, and the published fee scale makes budgeting easy.
When a private approver tends to suit
- Your project is large or unusual. Bespoke designs, basement conversions and complex structural schemes often benefit from an approver who can give more time to plan-checking and early advice.
- Speed matters. If your council has long waits for inspections and your programme is tight, a private approver's responsiveness can be worth a fee premium.
- Your architect or engineer has a working relationship with one. Design professionals who regularly work with a particular approver can resolve technical questions quickly, before they become site problems.
- You want a single point of contact. Approvers typically assign a named surveyor to your project rather than whoever is on duty.
One caution: because a private approver is paid by you (or via your builder), pick one on reputation and registration — not just the cheapest quote. Check the register before appointing.[4]

- Get both quotes. Council fees are published online; a private approver will quote in a day or two. Compare like for like — plan check plus all inspections.
- Verify registration. Private approvers must appear on the Building Safety Regulator's register of building control approvers — check the name exactly as quoted.[4]
- Ask your builder and designer. They deal with building control every week; their experience of local response times is worth more than any website.
- Confirm who books inspections. Whoever you appoint, put the inspection stages and booking responsibility in writing in your builder's contract.
- Plan for the certificate. The completion or final certificate is the document that matters when you sell — read completion certificates: what they are and how to get one so nothing is left loose at the end.
Your next steps
Choosing between council and private building control is a small decision inside a much bigger one: getting the whole project planned properly. Renovome builds approvals, inspection stages and their costs into your project programme from day one, so you can compare professionals on a like-for-like brief.
