Data Cleansing in Canterbury
Correcting and deduplicating the records a Canterbury business relies on. Cleansing is worth doing and worth doing once — without fixing whatever produced the mess, the same duplicates and blank fields reappear within a year and the exercise gets repeated at full cost.
Why this comes up
The problem
The CRM holds the same customer three times under different spellings. Mailings go out twice, reporting counts them separately, and nobody trusts the customer numbers.
What you get
What we deliver
- Profiling that quantifies the problem before anyone starts fixing it
- Deduplication with survivorship rules you agree, not whichever record was newest
- Standardisation of addresses, names, phone numbers and dates to one format
- Validation against authoritative sources where they exist, such as postcode data
- Records flagged for human review where a rule cannot decide safely
- Input controls at source, so the same mess does not accumulate again

Thirty minutes, no charge, no sales script. You leave with a written summary of what data cleansing would actually involve — whether or not you use us.

Data Cleansing in Canterbury — common questions
- How do you decide which duplicate to keep?
- By agreed survivorship rules — most recently updated, most complete, or from the most trusted source, field by field. Merging usually beats choosing, since the best data is often spread across the duplicates rather than concentrated in one.
- Will it get messy again?
- Yes, unless the input is fixed. Cleansing without addressing free-text entry, missing validation and duplicate creation is a treatment rather than a cure, and the same project gets commissioned again in about eighteen months.
- Can this be fully automated?
- Mostly, with a human queue for genuinely ambiguous cases. Two records with the same name at the same address may be a duplicate or may be a parent and child — automating that decision confidently is how you delete a real customer.
- Does data protection affect this?
- It does, in a helpful direction. UK GDPR expects personal data to be accurate and not kept longer than necessary, so cleansing and deleting stale records is a compliance obligation as well as an operational improvement.
- Do you work with businesses across Kent?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Canterbury and the surrounding Kent area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Canterbury businesses do you usually work with?
- Student-facing booking and ordering systems, and seasonal staffing tools for hospitality operators. Beyond that we work across Higher Education, Tourism & Heritage, Retail, Healthcare and Agriculture.
- Do you cover the areas around Canterbury?
- Yes — we work throughout South East, including Chelmsford, Colchester, London. Canterbury is an urban area of roughly 160,000+, and we take on work across the wider Kent region rather than the city boundary alone.
