Your property sale was progressing smoothly until your buyer’s solicitor sent the email. They need FENSA certificates for the replacement windows installed in 2015. You search through drawers, folders, and old paperwork but find nothing. The installer’s business card shows a disconnected phone number. Their website no longer exists. Your conveyancer warns that missing certificates could delay completion by weeks or collapse the sale entirely.
This scenario affects thousands of UK homeowners every year. FENSA certificates should accompany every window and door installation completed since April 2002, but they disappear, get lost during house moves, or were never issued by unregistered installers. Understanding how to obtain these certificates, and what happens when you cannot, determines whether your property sale completes or collapses.
FENSA (Fenestration Self Assessment Scheme) is a government authorised scheme created in April 2002 that monitors building regulation compliance for replacement windows and doors. The certificate provides proof that your window and door installations comply with UK Building Regulations and are registered with the local council.
Any replacement windows or fully glazed doors installed from 1 April 2002 onwards must have either a FENSA certificate or a Building Regulations completion certificate from your local authority. External doors with a glazed area exceeding 50% of the door surface specifically require FENSA certification. The scheme eliminates the need for separate building control applications by allowing registered installers to self certify their work meets required standards.
FENSA registered installers notify the scheme of completed installations, which then issues certificates to homeowners and registers the work with local authorities automatically. This streamlined process works perfectly when installers follow proper procedures. Problems arise when installers fail to register work, homeowners lose certificates, or non registered companies complete installations without building control approval.
Yes, windows and doors replaced since 1 April 2002 must be supported by a FENSA certificate or building regulations certificate to show legal compliance. Installing double glazing without proper certification breaches Building Regulations and can result in enforcement notices from your local authority. Properties lacking correct certification face difficulties when selling, potential enforcement action requiring retrospective applications, or necessitate purchasing indemnity insurance.
The legal requirement applies to all replacement installations affecting thermal performance and structural integrity. This includes standard window replacements, patio doors, French doors, conservatory glazing, roof windows, and external doors with significant glazed areas. Minor repairs like replacing broken glass panes without removing the entire window frame do not trigger certification requirements.
You can order replacement certificates through the FENSA website for £25 online or £30 by cheque. The process takes 6 to 7 working days after payment clears. The FENSA certificate search requires your postcode and house number to locate certificates linked to your property.
Follow these steps to obtain your replacement certificate:
This straightforward process only works if your original installer registered the work with FENSA. Many homeowners discover no records exist because installers were not FENSA accredited, forgot to register completed work, or the installation predates the 2002 regulations. If the FENSA search returns no results, you cannot obtain a replacement certificate because none was issued originally.

When no FENSA registration exists for your windows or doors, you must apply for retrospective certification through your local authority building control department. This process requires scheduling a physical inspection where a building control officer examines the installation quality, thermal performance specifications, and safety compliance.
A building control officer will verify proper installation, window tightness, appropriate glazing specifications for your property type, and compliance with current building regulations. Fees vary by council but typically range from £200 to £500 depending on the number of windows requiring assessment and your local authority’s charging structure.
The retrospective application process takes 4 to 8 weeks minimum from initial contact to certificate issue. This timeline assumes installations pass inspection on first assessment. Windows failing to meet building regulation standards require remedial work or complete replacement before certification. Properties with significant non compliance issues face costs reaching thousands of pounds for window replacement plus additional inspection fees.
Some installations cannot achieve retrospective certification because they fundamentally breach regulations. Single glazed windows installed in habitable rooms, inadequate thermal performance values, or structurally compromised installations will fail building control assessment. These failures leave you with three options: replace the windows entirely, purchase indemnity insurance accepting the breach, or find a buyer willing to accept the property with building regulation issues.
Conveyancers inquire about FENSA certificates through standard TA6 property information forms during property transactions. You must declare all replacement windows and doors installed since April 2002 and provide supporting certificates. Missing certificates trigger additional inquiries from buyers’ solicitors seeking explanations, retrospective applications, or indemnity insurance proposals.
The absence causes hold ups ranging from two weeks to complete sale collapse. Buyers become concerned about corner cutting, unregistered work, and potential building regulation breaches. Mortgage lenders scrutinise missing certificates carefully because non compliant installations affect property valuations and loan security. Many lenders decline applications until certificate issues resolve satisfactorily.
Ordering certificates through solicitors proves more expensive and slower than direct online ordering. Solicitors charge administrative fees for placing orders, typically £50 to £100 on top of the £25 FENSA cost. Cheque payments add processing delays before certificates are issued. Properties in conveyancing chains face particular pressure because every week of delay risks other parties withdrawing.
There is no easier way to sell a house today.
Technically yes, but practically very difficult. Selling without certificates requires either purchasing indemnity insurance (£50 to £150), obtaining retrospective building control approval (£200 to £500 plus 4 to 8 weeks), or finding a cash buyer willing to accept the property with documentation issues.
Indemnity insurance protects against future enforcement action by local authorities but does not prove building regulation compliance. Many buyers reject properties requiring indemnity policies, viewing them as evidence of substandard work. The insurance only covers the cost of enforcement proceedings, not the expense of bringing installations up to standard if local authorities demand compliance.
Estate agents struggle to market properties with missing FENSA certificates effectively. Disclosing certificate issues upfront deters viewings and reduces offers. Concealing the problem until conveyancing creates worse outcomes when buyers discover issues late and either withdraw or renegotiate prices downward substantially.
Estate agents require properties presented in sellable condition with complete documentation. They cannot resolve building regulation compliance issues or expedite certificate applications. Once conveyancing begins and certificate problems emerge, estate agents provide no practical assistance beyond encouraging you to resolve issues quickly to prevent buyer withdrawal.
| Sale Method | Timeline | Certificate Requirements | Documentation Costs | Completion Certainty | Commission/Fees |
|---|---|---|---|---|---|
| Estate Agents | 20 to 24 weeks | Must obtain before sale | £25 to £500+ | Buyer can withdraw | 1.5% to 3% plus VAT |
| Property Auctions | 8 to 12 weeks | Disclose non compliance | £25 to £500+ | Reserve price risk | 2.5% to 3.5% plus VAT |
| Property Saviour | 10 days | None required | Zero | Guaranteed completion | Zero |
Estate agents collect commission only after successful completion, creating misaligned incentives when documentation problems emerge. They pressure sellers to resolve issues quickly regardless of cost because delayed sale provides them no income. Their standard contracts offer no protection if buyers withdraw due to FENSA certificate complications.
The commission structure adds financial pressure after you have already spent money obtaining retrospective certificates or indemnity insurance. Charging 1.5% to 3% plus VAT on sale price, estate agents extract £3,000 to £7,000 from a £220,000 property sale. This comes on top of certificate costs, building control fees, and legal expenses resolving documentation issues.
Buyers introduced by estate agents typically require mortgages that demand full building regulation compliance. Mortgage lenders reject applications where FENSA certificate issues remain unresolved, forcing sale collapse after weeks of conveyancing work. You then face re marketing costs, additional estate agent fees, and starting the entire process again with no guarantee the next buyer will be more accommodating.
Property auctions disclose missing FENSA certificates in legal packs, deterring many bidders concerned about building regulation breaches. Investors attending auctions reduce bids substantially to account for retrospective application costs and compliance risks. Properties with significant documentation issues regularly fail to achieve reserve prices, remaining unsold whilst auction fees still apply.
The auction process demands upfront investment in legal pack preparation typically costing £1,000 to £1,500 regardless of sale outcome. You remain responsible for obtaining FENSA certificates or retrospective approvals before completion unless you accept severely reduced pricing that investors demand for taking on these burdens themselves. Auctions provide no guaranteed sale and no certainty about final selling price until bidding concludes.
We purchase properties regardless of missing FENSA certificates, building regulation breaches, or incomplete documentation. Our offer is 70% of realistic post-repair valuation, providing immediate certainty when traditional routes demand months of uncertainty and hundreds of pounds in certificate applications.
Completion happens in 10 days with cash transferred to your solicitor. We conduct our own due diligence and accept responsibility for obtaining retrospective approvals after purchase. Your missing certificates become our problem the moment we complete, removing the burden from your shoulders entirely.
| Method of sale | Value achieved | Fees | Timeframe | Is sale guaranteed? |
|---|---|---|---|---|
| Estate agents | 90–95% | 1–5% | 3–6 months | No – one in three sales collapse |
| Auctioneers | 70–80% | 2% plus | 2–3 months | No – half of properties don’t sell |
| Property Saviour | 70–80% | £0 | 10–28 days | Yes – 99% success rate |
Our pricing reflects the real costs and risks we absorb after purchase:
You receive 70% immediately with zero costs, zero documentation requirements, and zero risk that buyers will withdraw due to certificate problems. We receive 100% eventually after months of work, substantial investment obtaining retrospective approvals, and considerable risk that building control rejects installations entirely.
This division creates fair value for both parties when FENSA certificate issues make properties impossible to sell through traditional routes. The theoretical difference between our immediate 70% offer and eventual 100% sale through estate agents disappears when you account for certificate costs, conveyancing delays, buyer withdrawal risks, and months of stress managing documentation problems.
Our cash buying capacity removes the mortgage lender scrutiny that creates FENSA certificate complications. Banks and building societies demand complete building regulation compliance before approving loans. We purchase using company cash reserves, eliminating third party requirements for certificates, indemnity insurance, or retrospective applications.
This fundamental difference allows us to complete purchases in 10 days regardless of your window installation documentation status. No mortgage underwriter reviews your property. No surveyor flags missing certificates in valuation reports. No lender demands retrospective building control approvals before releasing funds.
Genuine cash buyers operate as registered companies with transparent financial histories. Fraudulent operators claim immediate cash purchase ability whilst actually sourcing finance or flipping properties to other buyers. This verification process takes 10 minutes and reveals the truth about claimed cash buying capability.
Visit the Companies House website and search for the company name exactly as it appears on their letterhead or website. The company profile displays incorporation date, registered office address, current and resigned directors, and most importantly, the charges section. Charges represent loans, mortgages, and finance agreements secured against company assets.

A company genuinely purchasing with cash should show minimal or zero charges. Extensive charges indicate the company borrows heavily to fund purchases, contradicting their cash buyer claims. Multiple charges from invoice finance companies, bridging loan providers, or development finance lenders reveal a company operating on borrowed money rather than genuine cash reserves.
Check director appointments across multiple companies using the director search function. Serial company formation with dissolved companies in directors’ histories suggests potential problems. Look for patterns of companies dissolved whilst owing money to creditors. This pattern indicates operators who abandon failed companies and start fresh entities to escape previous obligations.
Property Saviour operates as a registered company with full transparency on Companies House. Our financial structure, director history, and charge register demonstrate genuine cash buying capability without reliance on external finance for individual purchases. We encourage every seller to verify our credentials before accepting our offer.
Many inherited properties have replacement windows installed years or decades ago with no surviving documentation. Previous owners may have used unregistered installers, lost certificates during house moves, or never obtained building control approval originally. Inheritors cannot answer conveyancing inquiries about installations they knew nothing about until inheriting the property.
Tracing installers from 10 to 20 years ago proves nearly impossible. Companies dissolve, change names, or simply disappear from business directories. Even if you locate the original installer, they may lack records from installations completed decades earlier. Building control departments sometimes retain historical records but many councils digitised systems only recently, losing paper records from early 2000s installations.
These inherited property scenarios create impossible situations where you bear legal responsibility for documentation of work you never commissioned. Estate agents cannot sell properties without resolving certificate issues. Buyers withdraw when you cannot provide satisfactory answers to conveyancing inquiries. You face spending hundreds of pounds on retrospective building control for a property you never intended to own long term.
Property Saviour removes this impossible burden by purchasing inherited homes with complete documentation uncertainty. We accept responsibility for researching installation history, pursuing retrospective certificates, or replacing windows entirely if building control rejects existing installations. Your inheritance becomes our project the moment we complete the purchase.
Discovering missing FENSA certificates during conveyancing creates panic and threatens your property sale. Traditional routes demand weeks of delays, hundreds of pounds in application fees, and no guarantee that retrospective building control will approve your existing installations. Buyers withdraw. Mortgage lenders decline applications. Estate agents pressure you to resolve issues quickly whilst offering no practical solutions.
We offer immediate escape from this documentation nightmare. Complete our call back form with your property details and contact information. Our team will telephone within 24 hours to discuss your situation without pressure or obligation. We will ask about your window installations, whether you have any certificates, and your timeline for selling.
Within 48 hours of visiting your property, we will provide a written offer at 70% of realistic valuation. If you accept, we complete in 10 days with cash transferred to your solicitor. Missing FENSA certificates, retrospective building control requirements, and building regulation breaches become our responsibility after completion. You walk away with certainty and cash whilst we handle documentation problems.
Sellers consistently tell us the reduced price means nothing compared to eliminating months of conveyancing delays, certificate application stress, and risks that buyers will withdraw after weeks of waiting. Properties stuck in conveyancing chains collapse regularly when certificate issues emerge.
