The Bottom Line
Whether you’ve just bought a historic Georgian townhouse near Ramsgate Royal Harbour, a classic Victorian terrace in Margate, or a detached family home in Broadstairs, moving into a new property in Thanet is an exciting milestone. But here is the critical safety question most buyers overlook on moving day: how many copies of your front door key actually exist — and exactly who still has them?
The uncomfortable reality is: far more people than you expect.
Thanet’s property market is highly active and uniquely diverse. It features a heavy mix of long-established family residences, newly built estates at the edges of Westwood, and a massive number of seaside holiday lets and Airbnb conversions. Before a property’s keys reach your hands on completion day, that home has likely passed through an extensive chain of people—and many of those hands may have kept a working duplicate.
This guide walks through every category of person who might still hold a key to your new Thanet home, how an unforced entry can completely void your UK home insurance, and exactly how to secure your property before you unpack a single moving box.
The Short Answer: Who Could Have a Key to Your New Thanet Home?
If you’re in a rush to unpack, here is the quick summary. The following groups are the most common culprits for holding undocumented spare keys to your property:
Previous Owners — And their extended family, old housemates, or ex-partners.
Estate Agents & Letting Managers — Multiple viewings mean keys pass through numerous hands across Thanet.
Professional Cleaners — Often hired for deep holiday-let or pre-sale handovers.
Builders and Tradespeople — Given long-term access during recent renovations or extensions.
Neighbours & Former Keyholders — Trusted with emergency spares for parcel collections or alarm resets.
Dog Walkers & Pet Sitters — Granted regular, unsupervised access to the property.
Holiday Guests — If the property was previously used as a coastal rental or Airbnb.
1. Previous Owners & Holiday Guests
The previous owners handed over a set of keys at completion—but that is rarely the complete history of the property. Over years of living in the Thanet area, the average household steadily accumulates duplicate keys.
Furthermore, because Thanet has a incredibly high concentration of holiday homes and second properties, many houses changing hands in areas like Cliftonville, Kingsgate, or Broadstairs have spent years operating as holiday rentals. This means dozens of temporary guests, maintenance crews, and local key-holders have had direct access to the physical keys. When a property sells, the remote holiday owner rarely tracks down every single spare copy left with local contacts.
2. Estate Agents & Letting Agencies
During the sales process, your local estate agent held a set of keys—sometimes for many months if a chain collapsed or a sale dragged on. Busy agencies managing dozens of viewings across Margate, Ramsgate, and Broadstairs frequently cut extra copies for staff convenience or hand keys over to third-party surveyors, EPC assessors, and photographers without a strict physical audit trail.
3. Builders and Tradespeople
Thanet features a large amount of older, period coastal housing stock that frequently requires ongoing maintenance, damp-proofing, or modern extensions. If the property you bought was renovated, redecorated, or fitted with a new kitchen right before the sale, a substantial chain of contractors (plumbers, electricians, plasterers) likely had key access. Spares frequently get lost in tool bags, van glove boxes, or workshop hooks, completely forgotten about by the trade crews.
4. Coastal Neighbours
Leaving a spare key with a neighbour is one of the most common security habits in close-knit Thanet communities. While done with the best intentions, previous owners frequently forget to retrieve these emergency spares amidst the chaotic logistical pressure of moving day. The result? A complete stranger on your new street could be holding full access to your home.
Why This Matters: Security and Insurance
This isn’t just a theoretical worry. While Thanet is a beautiful place to live, residential break-ins do happen.
The biggest risk for a new buyer is your Home Insurance Policy. The Association of British Insurers (ABI) notes that almost all standard home insurance policies require you to take “reasonable precautions” to secure your property.
⚠️ Insurance Risk Note: If a break-in occurs and the police find no evidence of forced entry (because a criminal simply unlocked your door using an old, unaccounted-theft key), your insurer has the right to completely reduce or reject your payout claim.
Changing your cylinders on moving day eliminates this risk entirely, ensuring your physical security and your insurance policy are validated from day one.
What You Should Do: The Moving Day Checklist
Change the Cylinders Immediately: You rarely need to replace the entire expensive door handle or multi-point locking mechanism. A local Thanet locksmith can quickly and affordably swap out just the internal key cylinders (Euro-cylinders on uPVC doors or Mortice locks on timber doors) in under an hour.
Secure Side Gates and Outbuildings: Thanet properties often feature side alleys leading to rear gardens. Ensure any side gates or detached garages have fresh, high-security weatherproof locks.
Switch to a Secure Key Safe: If you need to grant access to local dog walkers, cleaners, or family members going forward, install a Master Locksmiths Association (MLA) approved digital key safe to prevent physical keys from being carried away and copied at a local hardware shop.
Frequently Asked Questions
How much does it cost to change the locks in Thanet? A standard cylinder change for a domestic home in Margate or Ramsgate typically costs between £80 and £150, depending on the lock type and security rating. We offer free, transparent, no-obligation quotes with no hidden call-out fees.
Should I look for a specific lock standard? Yes. To satisfy UK insurance criteria, look for locks that carry the BS3621 Kitemark (for timber doors) or a 3-Star TS007 Sold Secure rating (for uPVC and composite doors) to protect against modern snapping techniques.
The Bottom Line
Your new Thanet home should be your safe haven. The previous owners, their contractors, their agents, and their holiday guests belong to a past chapter of the property that should no longer have access to your front door. Changing your locks is the cleanest, most affordable way to draw a secure line under the past.
