The during-the-build route
Monitored Professional Consultants Certificates, explained.
Building from the ground up? A monitored PCC is the classic route. A RICS Chartered Building Surveyor inspects the build at its key stages, foundation level, blockwork up, roof on and a final visit at completion, then issues a six-year certificate accepted by most mortgage lenders as an alternative to a structural warranty.

What is a monitored PCC?
A Professional Consultants Certificate (PCC) is a document issued by a qualified construction professional, for us a RICS Chartered Building Surveyor, confirming that a newly built, converted or significantly extended property has been constructed to a satisfactory standard. It's accepted by most UK mortgage lenders as an alternative to a 10-year structural warranty, in line with Section 6.7 of the UK Finance Lenders' Handbook.
A monitored PCC is the original, ground-up version of that certificate. Rather than relying on a single inspection after the build is finished, the surveyor attends the site at the key construction stages, foundation level, the damp-proof course, the superstructure once the blockwork or frame is up, the roof once the building is weathertight, first fix, and a final visit at completion. At each milestone they check the work against the approved drawings and Building Regulations before it is covered up and can no longer be seen.
Because a professional has watched the build go up and verified the parts that later become hidden, a monitored PCC is accepted by the widest range of lenders of any PCC. It's the route we recommend whenever a build is starting from scratch or is still underway. If the works are already complete, a retrospective PCC is the alternative, certified after a single comprehensive inspection, though it's accepted by fewer lenders.

The stages we inspect during the build
We like to visit at the moments that matter, when the structure is visible and before it's covered up. The exact schedule flexes with your build, but these are the key stages we attend on a typical project.
- 01
Foundation level
Before the concrete is pouredWe inspect the excavations and foundations before they're covered: trench depth, ground conditions, any reinforcement, and that what's going in matches the engineer's design and the approved drawings. Once concrete is poured, the foundations can never be seen again, which is exactly why a lender wants a professional to have looked.
- 02
Damp-proof course & ground floor
Oversite, DPC and slabThe damp-proof course, the oversite preparation and the ground-floor construction are checked before the superstructure goes up. Getting damp protection and floor build-up right at this stage prevents problems that are expensive to put right later.
- 03
Framework / blockwork up
Superstructure to wall-plateWith the walls built up, we inspect the superstructure: blockwork or frame, cavity construction, wall ties, lintels over openings, and that the structure is being built as drawn. On a timber or steel frame, this is the visit that confirms the frame before it's clad and concealed.
- 04
Roof on
WeathertightOnce the roof structure and covering are on and the building is weathertight, we inspect the roof construction, the trusses or rafters, and the weatherproofing. This is the milestone that protects everything underneath, so it's a key stage on almost every monitored build.
- 05
Pre-plaster / first fix
Before finishes conceal the structureBefore plasterboard and finishes hide the structure and services, we inspect first-fix: the internal structure, insulation and any structural elements that won't be visible once the walls are closed up. The last chance to see the bones of the build.
- 06
Final inspection
On completion, before the certificate issuesA final visit on practical completion to inspect the finished property, pick up any snagging, and confirm the build has been completed to a satisfactory standard. Only once we're satisfied at this stage do we sign and issue the certificate, valid for six years from completion.
How a monitored PCC works, end to end
- 01
Get a fixed-fee quote
Tell us the address, the type of build and roughly where it's up to. We send a fixed fee based on the inspections your build needs, usually the same working day.
- 02
Agree the inspection schedule
Pay the deposit and we match you with a RICS chartered building surveyor covering your area. We set out the visits and book them around your build programme, with your builder, so nothing holds up the site.
- 03
Stage inspections during the build
We attend each key stage as the build reaches it, foundations, DPC, superstructure, roof, first fix, flagging anything that needs attention while it can still be put right easily.
- 04
Final inspection & signed certificate
On completion we carry out the final visit. Once we're satisfied, the balance is settled and the signed PCC is emailed to you, your conveyancer and your lender, valid for six years.
What we check across the build
Across the stage visits, a monitored PCC gives our surveyor eyes on the elements that a single post-completion inspection can never see:
- Excavations, foundations and ground conditions before concrete
- Damp-proof course, oversite and ground-floor construction
- Superstructure: blockwork, frame, cavity, wall ties and lintels
- Roof structure, covering and weatherproofing
- Drainage and below-ground services where accessible
- First-fix and structural elements before they're concealed
- Insulation and weatherproofing detailing
- Compliance with the approved drawings and Building Regulations
- Finished construction and snagging at completion
When a monitored PCC is the right fit
If the build hasn't started, or it's underway, monitoring is almost always the stronger choice. Here's where it fits best.
A self-build or custom home
You're building your own home and want a lender-recognised certificate without committing to a 10-year structural warranty. Monitored from the ground up, a PCC is the established route.
A new build starting from scratch
A developer or self-builder on a plot that hasn't broken ground, or has only just started. Inspecting from foundation level gives the strongest, most widely accepted certificate.
A small development of units
Several plots or apartments going up together. We monitor the build across the key stages and certify each unit on completion. Fixed fee per unit on schemes of six or more.
A conversion or major remodel mid-build
A barn, office or chapel conversion, or a large remodel that's underway. We pick up the build at the stage it's reached and inspect the milestones still to come.
Monitored PCC vs the alternatives
How a monitored certificate compares to a retrospective PCC and a structural warranty.
| Monitored PCC | Retrospective PCC | Structural warranty | |
|---|---|---|---|
| When it's done | During the build, stage by stage | After completion, one inspection | Registered before the build starts |
| Lender acceptance | Widest, accepted by most lenders | Narrower, varies by lender | Widely accepted |
| Inspection-led? | Yes, at every key stage | Yes, single visit | Spot inspections / audit-based |
| Validity | 6 years from completion | 6 years from inspection | 10 years |
| Best for | New builds & self-builds from scratch | Finished builds with no warranty | Developers wanting insurance cover |
Will my lender accept it?
A monitored PCC has the broadest lender acceptance of any Professional Consultants Certificate. Because the build has been inspected at each key stage by a qualified, insured professional, it sits comfortably on the list of acceptable cover in the UK Finance Lenders' Handbook alongside NHBC, LABC and the other warranty providers.
That said, individual lenders can still have their own conditions, so before you instruct we're happy to confirm your specific lender's requirements. Check whether your lender accepts a PCC.

What is a monitored Professional Consultants Certificate?
A monitored PCC is a Professional Consultants Certificate issued after a RICS Chartered Building Surveyor has inspected the build at its key construction stages, typically foundations, damp-proof course, superstructure, roof, first fix and completion. Because a professional has watched the build go up and verified it against the drawings and Building Regulations at each milestone, it's the form of PCC accepted by the widest range of mortgage lenders. It's the classic, ground-up route, and the alternative to a 10-year structural warranty such as NHBC or LABC.
How many site visits are there, and at what stages?
On a typical new build we attend the key construction stages: foundation level (before the concrete is poured), the damp-proof course and ground floor, the superstructure once the walls or frame are up, the roof once the building is weathertight, first fix before the structure is plastered over, and a final inspection on completion. That's usually five to six visits, though it flexes with the size and type of build, a single house differs from a phased development. We agree the inspection schedule with you and your builder at the outset so visits are booked around the build programme.
Why does the surveyor need to visit during the build?
Because the most important parts of a building are buried or hidden as it goes up. Once concrete is poured the foundations can't be seen; once the walls are plastered the structure behind them can't be checked. A monitored PCC is built on inspecting those elements at the moment they're visible. That's what gives a lender confidence the property was built to a satisfactory standard, and it's why a monitored PCC is accepted more widely than one issued retrospectively after the build is finished.
Will my mortgage lender accept a monitored PCC?
In almost all cases, yes. A Professional Consultants Certificate issued with stage inspections during construction is accepted by most UK mortgage lenders as an alternative to a structural warranty, under Section 6.7 of the UK Finance Lenders' Handbook. This is the key advantage of monitoring from the start: acceptance is far broader than for a retrospective PCC. We can still check your specific lender's requirements before you instruct.
How much does a monitored PCC cost?
Pricing is fixed and agreed up front based on the number of inspections your build needs, with no hourly billing or surprise add-ons. On developments of six or more units it's £600 per unit. Tell us the address, the type of build and roughly where it's up to, and we'll send a fixed-fee quote, usually the same working day.
We've already started building, is it too late for a monitored PCC?
Not necessarily. If the build is underway we pick it up at the stage it's reached and inspect the remaining milestones. The earlier we're appointed the better, because we can't certify a stage that's already been covered up, but plenty of builds come to us partway through. If construction is fully complete, a retrospective PCC is the route instead, and we'll tell you honestly which one fits.
How long is the certificate valid for?
Six years from completion. The certificate is signed by a RICS Chartered Building Surveyor carrying the required professional indemnity insurance, who takes professional responsibility for the statement they sign.
Is a monitored PCC the same as a structural warranty?
No, but it does a similar job for a mortgage lender. A structural warranty (NHBC, LABC, Premier Guarantee) is an insurance product that pays out for defined defects for ten years. A PCC is a professional's certificate, backed by their professional indemnity insurance, confirming the build was monitored and meets a satisfactory standard for six years. Both appear on the lender's list of acceptable cover, and a PCC is usually faster and cheaper to put in place. See our monitored vs retrospective and PCC vs warranty guides for the full comparison.
