What is Formedecon LTD?
Formedecon LTD is a UK-based forensic and investigative services firm that works for the legal profession. It describes itself as a team of forensic scientists, technical experts and expert witnesses — including former Forensic Science Service (FSS) experts, former senior police and investigative officers, and academics — who take on prosecution, defence, civil and family matters in the UK and internationally.
What it does
Its stated specialisms cover:
- Drink-drive and drug-drive work, including alcohol BAC calculations and toxicology
- Biological fluids and DNA
- Blood pattern distribution
- Road traffic accident (RTA) reconstruction
- CCTV analysis
- Forensic psychology
- Fingerprints
- Document examination
- Crime scene investigation (CSI), including PIDs
- Arson investigation
The firm says it writes reports for use in court and tribunals and attends hearings to give live evidence.
Who it is for
Formedecon states it accepts instructions from solicitors (both Legal Aid Agency-funded and privately funded cases), barristers using Direct Access, and private companies and businesses. It also offers a standard alcohol questionnaire for those needing an alcohol BAC calculation or a drink-drive expert report.
What to consider
If you are instructing an expert for a case, the relevant questions are whether the specific discipline you need is covered, whether the expert can attend court in person, and whether the report will be usable in the forum you are in (criminal, civil or family). Formedecon presents itself as impartial and used to working for both prosecution and defence, which matters if you want an expert whose evidence will withstand cross-examination.
A practical next step: identify the exact issue in your case — for example, a disputed BAC reading or a collision reconstruction — and ask the firm which named expert would handle it, what their qualifications are, and their availability for a hearing date.
When should a solicitor instruct a forensic expert for a drink drive or drug drive case?
Instruct a forensic expert early in a drink drive or drug drive case whenever the prosecution's case rests on an interpretation your client disputes: a back-calculation of alcohol at the time of driving, the reliability of a blood or urine sample, the effect of a prescribed or recreational drug, or the chain of custody from sample to laboratory. Formedecon LTD is one example of a provider that covers this ground, listing drink drive and drug drive expertise, alcohol BAC calculations, toxicology and biological fluids among its services, and stating that it accepts instructions from solicitors on both legal-aid-funded and privately funded cases, as well as direct access from barristers.
Situations that justify early instruction
- A borderline reading. If the measured alcohol level is only just above the limit, a back-calculation to the time of driving may bring the client under it — but the calculation depends on elimination rates, drinking pattern and timing, so it needs an expert rather than an assumption.
- A client who denies recent drinking or driving. Where the prosecution timeline and the client's account conflict, an expert can test whether the readings are consistent with the account.
- Drug drive allegations. These often turn on whether a substance was impairing, at what concentration, and whether a prescribed medicine is a legitimate explanation. Toxicology input shapes both the defence and plea negotiations.
- Sample or procedure challenges. Disputes about how a sample was taken, stored or analysed, or about the reliability of the analytical method, are technical arguments that need expert framing before they are raised.
- Sentence and special reasons. Even where a conviction is likely, expert evidence can support a special reasons argument or mitigate sentence by putting the readings in context.
Practical next steps
Ask the instructing solicitor or barrister what the prosecution's expert has concluded, obtain the raw data rather than only the summary report, and put the client's account of drinking or drug use in writing at the outset. Timing matters because elimination and metabolism calculations depend on the interval between the alleged driving and the sample, and because experts need lead time to prepare a report and attend court. Formedecon states that its team writes reports for court and tribunals and regularly gives live evidence, which is the standard to look for when selecting an expert.
How to choose between experts
| Consideration | What to check |
|---|---|
| Relevant discipline | Alcohol back-calculation, toxicology, or drug impairment — not a generalist |
| Court experience | Willingness to attend hearings and give live evidence |
| Funding route | Whether the expert accepts legal aid rates or private instructions |
| Report style | Clear, concise reports that a non-specialist tribunal can follow |
| Availability | Enough time before the hearing date to prepare and disclose |
For comparison, the Forensic Science Regulator publishes standards for forensic providers, and the Expert Witness Institute and Academy of Experts both maintain directories of accredited experts.
How is a BAC calculation used to challenge a drink drive charge?
A BAC calculation estimates a driver’s blood alcohol concentration at the time of driving, then tests whether that estimate is consistent with the prosecution’s case. It can challenge a drink-driving charge by showing the alleged reading may not reflect the alcohol actually in the driver’s system when they were behind the wheel, or by testing the reliability of the evidential reading itself.
Where the calculation bites
- Back-calculation: If a breath or blood sample was taken some time after driving, a forensic scientist may calculate what the level was likely to have been at the time of driving. This matters when the driver claims they drank after driving, or when there was a delay between driving and testing.
- Forward calculation: From a known account of what was consumed and when, an expert can estimate what the reading should have been. If the estimate is far below the alleged reading, it can support a challenge.
- Alcohol elimination rates: People eliminate alcohol at different rates, and factors such as body weight, sex, food and metabolism affect the estimate. A calculation can show the range of possible readings rather than a single figure.
- Toxicology and biological fluids: Where blood or urine analysis is involved, a calculation may test whether the analytical result is consistent with the claimed drinking history.
- Questioning the reading: Even where the calculation broadly agrees with the prosecution, it can still be used to probe calibration, sample handling or the assumptions behind the alleged figure.
What it does not do
A BAC calculation is an estimate, not a re-measurement. It depends on the accuracy of the drinking history, timing and individual factors. It is strongest when there is a clear timeline and reliable information about what was consumed. It is weaker when the account is vague or inconsistent.
Practical next step
If you are instructing a forensic expert, gather a precise timeline: what was drunk, when, how much, what was eaten, when driving occurred, and when the sample was taken. A standard alcohol questionnaire is often used to capture this. The calculation can then be tailored to the specific charge and the evidence served.

What qualifications and court experience should an expert witness have for criminal or civil proceedings?
An expert witness should combine three things: recognised expertise in the relevant field, training or experience in the specific area under dispute, and a working knowledge of court procedure and the duties of an expert. Qualifications alone are not enough; the court also looks at whether the person can explain complex material clearly and stay within their proper role.
Core qualifications
- A relevant degree, professional qualification or equivalent, plus evidence of continuing practice in that field.
- Specific training or accreditation for the forensic discipline involved, where such schemes exist.
- A track record of casework, research, teaching or publication that shows depth, not just general familiarity.
Court experience
- Prior experience producing reports for criminal, civil, family or tribunal proceedings.
- Familiarity with the duty to the court, impartiality, and the limits of expert opinion.
- Experience giving live evidence and being cross-examined, including under challenge to methodology.
- Awareness of disclosure, continuity of evidence, and the standards expected for the jurisdiction.
What to check in practice
| Area | What it tells you |
|---|---|
| Qualifications | Whether the person is technically competent in the subject |
| Casework history | Whether they have applied that knowledge to real disputes |
| Court appearances | Whether they can withstand scrutiny and communicate clearly |
| Regulatory or professional standing | Whether there are complaints, sanctions or conflicts |
| Report quality | Whether the reasoning is transparent and reproducible |
For a concrete example, a solicitor defending a drink-drive charge may need someone who can both perform BAC calculations and explain the assumptions behind them in court. Formedecon LTD describes a team drawn from former forensic science service experts, senior police and investigative officers, and academics, covering areas such as drink-drive and drug-drive work, toxicology, DNA, blood pattern distribution, road traffic collision reconstruction, CCTV, forensic psychology, fingerprints, document examination, crime scene investigation, arson and alcohol BAC calculations.
As a next step, ask a prospective expert for a CV that lists qualifications, relevant casework, the courts they have given evidence in, and any professional memberships or accreditation. Then ask whether they have handled a case with facts similar to yours. That combination — subject expertise, relevant experience and tested court performance — is usually more useful than a long list of letters after a name.
Which forensic services does Formedecon provide for road traffic accident reconstruction and CCTV analysis?
Formedecon provides road traffic accident (RTA) reconstruction and CCTV analysis as two of its listed forensic and technical services, alongside drink-drive and drug-drive work, toxicology, DNA, blood pattern distribution, fingerprints, document examination, arson, CSI, forensic psychology and expert witness evidence. The firm describes a team of forensic scientists, technical experts and expert witnesses — including former FSS experts, former senior police and investigative officers, and academics — who take instructions in prosecution, defence, civil and family matters in the UK and worldwide.
How each service is typically used
RTA reconstruction suits cases where the sequence of a collision is disputed: solicitors, barristers on direct access, insurers or private businesses may need a reconstruction to test accounts of speed, position, impact or driver behaviour. The output is normally a written report for court or tribunal, with the expert available to give live evidence.
CCTV analysis is relevant when video footage is central to identification, timing, movement or the sequence of events — for example, linking a vehicle or person to a location, or clarifying what footage does and does not show. Again, the deliverable is a clear report and, where needed, court attendance.
What to weigh before instructing
- Scope match: confirm the specific question you need answered (impact speed, sight lines, footage authenticity, timeline) rather than commissioning a broad "accident report".
- Forum: state whether the matter is criminal, civil or family, and whether it is legally aided or privately funded, since that shapes report format and timescales.
- Evidence handling: for CCTV, ask early about original footage, chain of custody and whether enhancement or frame-by-frame analysis is required.
- Expert evidence: check the expert's availability for court and their familiarity with the relevant tribunal.
A practical next step is to call Formedecon on the number listed on its site, 01388 811003, with a short case summary and the specific questions you need the expert to address. The site also links to a standard alcohol questionnaire for BAC or drink-drive instructions, which indicates the level of detail the firm expects at the outset.
How do I instruct Formedecon or complete the alcohol questionnaire for a case?
Instruct Formedecon by contacting the firm directly with your case details, then complete its standard alcohol questionnaire if the case involves a BAC calculation or drink-drive expert report. The page lists the phone number 01388 811003 and states that the questionnaire is available via a link at the top of the page.
Who can instruct
Formedecon says it accepts instructions from:
- Solicitors, whether legally aided or privately funded
- Barristers using Direct Access
- Private companies and businesses
It handles prosecution, defence, civil and family matters, in the UK and worldwide.
What to have ready when you call or write
The site does not publish an email address, so phone is the clearest route shown. Before you make contact, gather:
- The case type and current stage, including any court or hearing dates
- The specific question you need answered, such as a BAC calculation or drink-drive report
- Custody, breath, blood or urine test records, if relevant
- Timings of drinking, driving and testing, and any witness accounts
- Funding route, so the firm can confirm whether it can take the instruction
- Any deadline for the report or for service of evidence
Completing the alcohol questionnaire
The questionnaire is the firm's standard route for alcohol BAC calculations and drink-drive expert reports. Treat it as the factual foundation for the expert's opinion: incomplete or inconsistent answers can undermine the report. Work through it with the client or the person who holds the records, and check it against the custody and test documents before returning it.
A practical sequence
- Call 01388 811003 to confirm the firm can take the case and discuss timing and funding.
- Complete the alcohol questionnaire if the matter is a BAC or drink-drive case.
- Send the questionnaire with the supporting records the firm asks for.
- Agree the report deadline and whether live evidence at court is likely.
For a drink-drive case with a hearing in three weeks, for example, call first to check availability, then return the questionnaire the same week so the expert has time to review the test records before drafting.
