Best Marketing Agency for Estate Agents in London: How to Choose

By the Oski Marketing team · Updated 5 October 2026 · 6 min read

The best marketing agency for a London estate agent wins you more vendor instructions, not just likes. It turns real listing photos into short video, makes sure every valuation enquiry is followed up fast, builds channels you own alongside the portals, and knows the rules on material information, housing ads and texting vendors.

What should an estate agent's marketing actually achieve?

More valuation requests from vendors and landlords in your patch, and more of those valuations turning into instructions. Buyer enquiries matter, but the portals already deliver most of them. The scarce thing is the vendor who has not yet chosen an agent.

That changes what good marketing looks like. Posting every new listing is useful, but it mostly reaches buyers. Vendor marketing is about proof that you sell homes like theirs, on their street, for a sensible price, and that you are easy to deal with. An agency should ask how many valuations you do a month, how many turn into instructions, and where those vendors came from, before it suggests anything.

How should an agency handle valuation enquiries?

It should check them first, because a slow reply loses vendors to the agent down the road. Ask the agency to test your own process: request a valuation through your website, your Google profile and a portal, then time the replies. Good practice is simple:

1. Instant acknowledgement that confirms the request and says when someone will call.
2. A same-day call from a named person, not a generic office line that rings out.
3. A useful follow-up after the valuation: comparable sales, your marketing plan for that home, and a clear next step.
4. A record of every valuation and where it came from, so you can see which channels produce instructions.

The marketing only works if this part works. Ten extra valuation requests are wasted if half of them wait two days for a call.

Can you text or email vendors who requested a valuation?

You can reply to their request, but ongoing marketing needs a proper basis. Under PECR, texts count as electronic mail, and the ICO says you can only send marketing to individuals with consent or under the soft opt-in, which needs details collected during a sale or negotiation and a clear chance to opt out when you collected them and in every message. A valuation form with a clear, unticked opt-in for market updates is the safe route. Our guide to PECR marketing rules covers the details. This is a general guide, not legal advice.

How should listing video and social media be done?

Use the property's real photos and footage, cut into short vertical video with clear captions: price, area, key features and a call to action. Never add rooms, views or furniture that are not there. Listings carry legal duties too. National Trading Standards' material information guidance, published in November 2023, sets out information listings should include, such as price, council tax band and tenure, and that duty does not disappear because the listing is a 30-second video.

For vendor marketing on social, the best content is often sold boards, "just sold on your street" posts, honest local market updates and short clips of your team at work. Our starter guide to Facebook and Instagram ads explains campaign set-up.

What should an agency know about property ads on Meta?

It should know that housing is a Special Ad Category. Meta's own documentation lists housing alongside employment and financial products, and says advertisers reaching Europe have had to declare relevant Special Ad Categories since December 2021. Declaring it changes which targeting options are available. An agency that sets up property ads without mentioning this either does not know or has not checked.

How do you reduce dependence on the portals?

You build channels you own alongside them, rather than leaving the portals. That means a website with valuation pages per area and recent sales, a Google Business Profile with steady reviews, an email list of people who opted in to market updates, and social accounts with real local content. Make sure your business owns the Google profile and the agency is added as a manager: owners can add or remove users and delete the profile, managers cannot.

How do you compare agencies for an estate agency?

On that last row: the ASA treats unqualified claims like "No.1" or "best" as objective claims that need evidence. For general questions to ask any agency, see our list of 15 questions to ask before you hire a marketing agency.

Where Oski Marketing fits

Oski Marketing works with independent estate and letting agents in London and the South East. We test how your valuation enquiries are handled, turn your real listing photos into short video, and run paid social and Google campaigns pointed at vendors. Paid social management starts from £600/month plus ad spend paid directly to Meta, on a rolling contract, and you keep ownership of your accounts and data.

We are not the right fit for large multi-branch groups that need a full in-house style team, for anyone who wants AI-invented property scenes, or for agents who want to market to bought lists without consent.

What to do this week

1. Request a valuation through your own website and time how long the reply takes.
2. Check your valuation form has a clear, unticked opt-in for market updates.
3. Confirm you are the owner of your Google Business Profile and list who else has access.
4. Turn your last three sales into short "just sold" posts using the real photos.
5. Count last month's valuations and instructions, and write down where each came from.
