Quick answer: a good letter campaign is targeting plus persistence. Send a short, personal letter to the owner or registered office, follow up two or three times over several weeks, and give one clear way to respond. Targeting the right owners is what turns a 1% response into something far better.
Before you can contact anyone, you have to know who to contact. GalimAI finds the property owners most likely to sell - you can size a target list for your area in plain English, then use the methods below.
Getting the address
For a company-owned property, the registered office is on the public Companies House record. For the property itself, HM Land Registry title records show the registered proprietor. See finding property owner contact details.
Writing the letter
Keep it short and human: who you are, that you are interested in their specific property or situation, and one simple call to action (a phone number or email). Avoid gimmicks. A letter that reads like a real person wrote it to a real owner beats a glossy mailshot every time.
Cadence and response rates
One letter is a reminder; three is a campaign. Space touches two to three weeks apart. Response rates vary widely, but relevance is the biggest lever - a letter to an owner whose company is low on cash with an unlettable EPC will always outperform a blind mailing.
Compliance
Postal mail to a business address is lighter-touch than email or calls, but UK GDPR still applies to personal data you hold. Keep a suppression list and honour any request to stop. General guidance, not legal advice.
Why it's an opportunity
Letters win because almost nobody sends them well, and because they reach owners no other channel does.
- Cut-through - a real letter stands out in an empty letterbox.
- Fewer hurdles - registered-office mail is straightforward.
- Targeting multiplies it - relevance beats volume.

Do letter campaigns to property owners still work?
Yes. Letters reach owners who ignore digital channels and stand out because so few are sent well. Relevance and follow-up matter more than volume.
Where do I get the owner's address?
Companies House lists the registered office of a company owner; HM Land Registry shows the registered proprietor of a property. Both are public records.
How many letters should I send?
Plan a sequence of two to three letters spaced two to three weeks apart, rather than a single send. Persistence lifts response rates.
