Retrospective Professional Consultants Certificates, explained.
Already finished the build, conversion or extension? A retrospective PCC can certify what's been done, without the cost or timescales of a traditional structural warranty. It's a route worth understanding carefully: not every lender accepts one, so we check yours before you commit.

What is a retrospective 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. When issued during construction, it is 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 retrospective PCC is the same document, issued after construction is complete rather than alongside the build. Instead of a series of monitoring inspections during the works, the certificate is supported by a single comprehensive site inspection by a chartered surveyor combined with a review of whatever paperwork is available: Building Regulations sign-off, drawings, service certificates, structural calculations and so on.
The certificate itself is identical: a six-year document signed by a qualified professional carrying the required £1m of professional indemnity insurance, who takes professional responsibility for the statement they sign. What differs is lender acceptance. A retrospective PCC is accepted by fewer lenders than one issued during the build, and it varies from lender to lender. It's a grey area best navigated with care, so the right first step is always to check your specific lender before you commit. We do that for you.

When you might need a retrospective PCC
These are the six situations we're asked about most. If your scenario isn't listed, get in touch and we'll tell you straight whether a PCC is the right fit before you commit.
Selling a property you built or extended
Your buyer's solicitor or lender has asked for evidence the work was carried out to building standards. A retrospective Professional Consultants Certificate can provide it, though acceptance varies by lender, so we check your buyer's lender first.
Remortgaging after major works
Switching lenders, releasing equity or coming off a self-build product? If the property was newly built, converted or extensively renovated within the last six years, your new lender will usually want a PCC on the file.
Buying a finished property without a warranty
A self-build, conversion or developer one-off where no NHBC, LABC or Premier warranty was put in place. We inspect on your behalf and certify what we find.
Build complete but warranty cover lapsed or missing
The original warranty never materialised, was issued by a provider the lender no longer accepts, or expired before the property reached the market. A PCC restarts the six-year clock.
Auction completion within tight timescales
Auction completions don't wait. A retrospective PCC can be issued in days rather than weeks, usually well inside a 28-day completion window.
Refinancing a development for onward sale
Developer exit finance, bridging-to-term refinances and BTL switches frequently require a PCC where no structural warranty exists or where the warranty provider isn't on the lender's panel.
The retrospective process, step by step
Six steps from first enquiry to a signed certificate in your inbox, typically inside 7 working days from inspection, or three on our priority service for an extra fee.
- 01
Online enquiry
Tell us the address, what was built or converted, when it was completed and which lender (if any) has been mentioned. Two minutes online, or a WhatsApp message.
- 02
Fee proposal and deposit
We send a fixed-fee quote: £950 for a single unit, £600/unit for six or more, bespoke pricing on 50+. Pay the deposit to lock in your slot and your surveyor.
- 03
Document review
We ask for Building Control sign-off, planning consents, architect's drawings, electrical certificates (EICR/EIC), gas safety records, structural calculations, FENSA / CERTASS window certificates and any other paperwork you have. The more we have, the smoother the inspection.
- 04
On-site inspection
A RICS Chartered Building Surveyor attends the property and carries out a comprehensive inspection: structure, weather-tightness, services, internal finishes, drainage and external envelope. Typically half a day on a single unit; longer on larger developments.
- 05
Draft certificate review
We send you a draft for review before anything is finalised. If we've flagged remedial items, you decide whether to address them or accept the certificate with caveats.
- 06
Final invoice and certificate issued
Pay the balance and the signed PCC is delivered by email, valid for six years from the inspection date. Your conveyancer, lender or buyer can have a copy in the same email.
What we inspect on site
A retrospective inspection is comprehensive by design: the certificate has to stand on a single visit, so the surveyor looks at everything they can reasonably access. The list below covers the typical scope on a residential property.
- Foundations (where exposed or where access permits)
- Load-bearing structure, beams, lintels and bearings
- Damp-proof course continuity and weather-tightness of the envelope
- Roof structure, covering, flashings and rainwater goods
- External walls, render, brickwork, pointing and cracking patterns
- Window and door installations, sealing and weather-stripping
- Internal finishes, junctions and signs of settlement or movement
- Drainage, soil-stack venting and any visible underground runs
- Insulation continuity (loft, walls and floors where accessible)
- Electrical, gas and plumbing services: visual and certificate review
Documents that help the process
You don't need every document on the list; we work with what you have. The more we can review in advance, the smoother the inspection and the cleaner the certificate. If you're missing anything fundamental, we'll tell you straight away.
- Building Regulations completion certificate (or full plans approval + final inspection notice)
- Planning permission and any approved conditions
- Architect's or designer's drawings, as-built where possible
- Structural engineer's calculations and design notes
- Electrical installation certificate (EIC) and any EICR reports
- Gas safety certificate (where gas is installed)
- FENSA, CERTASS or equivalent window installer certificates
- Drainage / connection records and any CCTV survey reports
- Insulation, air-tightness or SAP / EPC paperwork
- Roofing, damp-proof course and structural-product manufacturer warranties
What happens if defects are found?
We never sign a certificate for a property we haven't satisfied ourselves about. That said, an inspection occasionally turns up items that need addressing: an incomplete fire-stopping detail, a section of roof underfelt that's torn, a missing structural product warranty, or a Building Control item that was never quite closed out. When that happens, we send you a draft certificate together with a list of findings and you decide what to do next.
Fix and re-inspect
You address the items, we revisit, and the certificate issues clean. Best route if a lender is waiting on a clean PCC.
Accept with caveats
Items are noted on the face of the certificate. Some lenders accept this with a retention; we'll flag the likely position in advance.
Withdraw
You walk away and pay only for the inspection time. No certificate is issued and no sunk cost on something that wasn't going to work.
Retrospective PCC vs the alternatives
The three things lenders typically see on a file where the property was built or significantly altered. Each has its place: here's how they line up.
The comparison above is general guidance. Individual lenders sometimes have specific requirements; always confirm via the UK Finance Lenders' Handbook or ask us before you commit.
Will my lender accept a retrospective PCC?
Here's the honest position. A Professional Consultants Certificate issued during constructionis accepted by most UK mortgage lenders, in line with Section 6.7 of the UK Finance Lenders' Handbook. A retrospective PCC, issued after the works are finished, is a more limited picture: fewer lenders accept one, and the position differs from lender to lender. It's a grey area, and anyone telling you every lender will accept a retrospective certificate isn't being straight with you.
That's exactly why we check first. Before you book, tell us your lender and we'll establish whether a retrospective PCC will satisfy them. If it will, we get on with it. If it won't, we'll tell you straight away and talk through the alternatives, rather than take an instruction for a certificate your lender won't accept.
Use the lender check toolRetrospective PCC: frequently asked questions
Everything we get asked about retrospective certification, in one place. If your question isn't here, message us on WhatsApp and we'll come back the same working day.
Can I really get a PCC after the build is finished?
Yes. A Professional Consultants Certificate can be issued retrospectively based on a thorough site inspection together with a review of the available paperwork, and is valid for six years from the date of our final inspection. Acceptance is the important caveat: while a PCC issued during construction is accepted by most UK lenders, a retrospective PCC is accepted by fewer, and it varies from lender to lender. That's why we check your specific lender's requirements before you book, and tell you straight if a retrospective PCC won't work for them.
How is a retrospective PCC different from a PCC issued during the build?
The end document is the same. A PCC issued during the build is supported by periodic inspections as the works progress; a retrospective PCC is supported by a single comprehensive site inspection plus documentary evidence of the work that was carried out (Building Regulations sign-off, drawings, service certificates and so on). The practical difference is lender acceptance: a monitored PCC is recognised by most lenders, whereas a retrospective one is accepted by a narrower set, which is why we check your lender before you commit.
Will my mortgage lender accept a retrospective PCC?
It depends on the lender, and we'll be straight with you: a retrospective PCC is accepted by fewer lenders than a PCC issued during construction. Some accept them; others insist on a PCC supported by monitoring inspections during the build, or on a structural warranty. Because it varies, we check your specific lender's requirements before you book, and if a retrospective PCC won't be accepted by your lender, we tell you up front rather than take the instruction.
What if I don't have all the paperwork?
It's rarely a deal-breaker. We work with what you have and what we can verify on site. For instance, where Building Control records have been lost, we may rely on the surveyor's on-site assessment plus a Regularisation Certificate from the local authority. We'll tell you upfront if anything will affect the certificate's scope.
How long does a retrospective PCC take?
From booking the inspection to the signed certificate landing in your inbox is typically 7 days. We have surveyors covering every UK county, so an inspection visit is usually possible within a week of you confirming the booking. If you're against a deadline, a 3-day priority turnaround is available for an extra fee.
What if the surveyor finds defects on inspection?
We send you a draft certificate before anything is finalised. If we've flagged remedial items, you have three choices: fix the items and we re-inspect; accept the certificate with the items noted (some lenders accept this with retentions); or withdraw and pay only for the inspection time. We never sign a PCC for a property we haven't satisfied ourselves about.
How much does a retrospective PCC cost?
Pricing is fixed and transparent: £950 for a single unit, £600 per unit on developments of six or more, and bespoke pricing on 50+ unit schemes. Retrospective certificates are priced the same as PCCs issued during construction. There's no surcharge.
Does the property need to be unoccupied for the inspection?
No. We work around occupants, whether that's tenants, your buyer in residence on a delayed completion, or you yourself. Where access to specific areas (loft, basement, plant room) is restricted, we ask in advance so the visit is productive.
How old can the property be?
There's no hard cut-off, but the inspection has to be able to confirm the property meets the relevant standards at the time the works were carried out. We're comfortable issuing PCCs on properties built up to about 10 years ago provided the documentary trail is reasonable; older completions are assessed case by case.
Can a retrospective PCC be backdated?
No, and you wouldn't want one. The certificate is signed and dated on the day we satisfy ourselves the property meets the standards, and is valid for six years from that date. That date is what lenders rely on.
Can you certify part of a property, just the extension, for instance?
Yes. Where only a specific element of the property has been built or significantly altered (extension, loft conversion, basement, garage-to-habitable conversion), we can issue a PCC scoped to that element. The certificate scope is set out clearly so there's no ambiguity for the lender.
How is a retrospective PCC different from indemnity insurance?
They're solving different problems. Indemnity insurance protects against a specific named risk (often a missing Building Regulations certificate or a planning irregularity) but doesn't involve any inspection or certification of the building itself. A retrospective PCC actively confirms, after on-site inspection, that the property has been built to acceptable standards. Lenders treat them differently.
Can you do it before exchange of contracts on a sale?
Yes, and that's a common scenario. We can have a draft to your conveyancer within a week of inspection so the certificate can be released alongside the contract pack.
Do I need to be on site for the inspection?
Helpful but not required. The surveyor needs access (keys, codes, or a contact on site). We'll always send the inspecting surveyor's details ahead of the visit.
What happens if the certificate is later challenged?
Every PCC we issue is backed by £1m of professional indemnity insurance on an aggregate basis. The certificate is the consultant's professional statement, and any subsequent claim is brought against the consultant's PI policy, which is why lenders require a minimum level of PI cover from the certifying professional in the first place.
