How An Upgraded Website Increased A London Estate Agent’s Sales and Rentals By Over 25% Between April and September 2025
Table of Contents
Key Takeaways
🔑 For estate agents, the website is the showroom. A poorly performing site does not just lose traffic — it loses vendors, landlords and applicants to competitors who look more credible online before a single conversation has taken place.
🔑 Speed, search functionality and mobile experience are the three non-negotiables for any estate agency website in 2025. Weakness in any one of them costs business in ways that are rarely visible until you fix them.
🔑 The biggest gains often come not from attracting more visitors but from converting the visitors already arriving. A site that turns browsers into enquiries is worth considerably more than a site with higher traffic that loses people before they act.
Estate agency is a peculiar business to be in right now. The market moves in ways that nobody predicted with any consistency, the regulatory environment keeps shifting, and the portal duopoly — Rightmove and Zoopla sitting between every agent and their potential clients like very expensive middlemen — has changed the economics of how independents compete in ways that are still working themselves out.
In that context, an independent London estate agent’s website might seem like a secondary concern. The listings are on the portals. The vendors find you through word of mouth or a board outside a property they liked the look of. Why does the website matter that much?
It is a reasonable question. The answer, as a fictitious but entirely plausible agency we will call Hartley & Cross discovered between April and September 2025, is that it matters rather a lot. Enough to shift their combined sales and rentals figures by more than twenty-five percent across six months. Enough that the senior partner, a pragmatic woman called Caroline who had been sceptical about the whole project from the start, described it afterwards as the best money the business had spent in five years.
Who Hartley & Cross Are
Hartley & Cross is a mid-sized independent estate agency operating across three areas of South West London — the kind of agency that has been around long enough to have genuine local knowledge, a solid reputation among the professional demographic that dominates its patch, and a team that takes real pride in the service they deliver.
What they also had, until early 2025, was a website that had last been meaningfully updated in 2019. It was not embarrassing exactly. The branding was consistent, the property listings pulled through from their CRM, the contact details were correct. But it was slow, it handled property searches poorly on mobile, the photography presentation was dated compared to competitors, and the content — the area guides, the landlord advice section, the seller resources — had not been touched in years and showed it.
Nobody at Hartley & Cross thought the website was a serious problem. It functioned. People could find properties on it. That felt like enough.
It was not enough. But that took some persuading to establish.

What The Data Actually Showed
The first conversation about the website was not about design or branding or content. It was about numbers. Specifically, what the existing site was actually doing with the people who arrived on it — because that is where the real story tends to live.
The traffic was reasonable. Hartley & Cross had decent local search visibility for their core area terms and a reasonably well-maintained Google Business Profile that drove consistent footfall to the site. The problem was not people arriving. The problem was what happened next.
The mobile bounce rate — the proportion of phone users who arrived and left without interacting with anything — was sitting at sixty-eight percent. More than two thirds of mobile visitors were leaving almost immediately. Given that mobile accounted for seventy-one percent of all site visits, this was not a peripheral problem. It was the central problem, dressed up as a website that was broadly working fine.
The property search function on mobile was the specific culprit. Filters that required precise tapping on small touch targets, results pages that loaded slowly and displayed properties in a format better suited to a desktop screen, map search that was essentially non-functional on a phone. In a market where applicants — particularly the younger professional demographic that makes up a significant proportion of London renters — conduct almost their entire property search on a smartphone, a broken mobile search experience is a catastrophic weakness.
There were other issues. The average page load time was five point eight seconds. The property photography, which on the portal listings looked perfectly acceptable in standard display sizes, was being loaded at full resolution on the website and taking an age to appear. The valuation request form — one of the most important conversion points on any estate agency website — was buried three clicks deep and required filling in seven fields before submission. The area guides had broken internal links, referenced local amenities that had closed and contained rental price data that was almost three years out of date.
None of these things were dramatic failures in isolation. Together they were quietly and consistently losing the business enquiries it never knew it was losing.
The Rebuild — What Changed
The project ran across February and March 2025 with the new site going live at the start of April. The brief was clear: mobile first, fast, conversion focused, with content that actually reflected the agency’s genuine local expertise rather than the generic placeholder material that had accumulated over years of neglect.
Mobile Experience
The property search was rebuilt from the ground up with mobile users as the primary consideration rather than an afterthought. Large touch targets, simplified filter options, fast-loading results in a format that works naturally on a vertical screen, and a map search that actually functions on a phone. The kind of search experience that Rightmove and Zoopla deliver as standard — because the volume of their mobile traffic forced them to solve this problem years ago — was now replicated on the Hartley & Cross site itself.
This matters for a reason beyond user experience. Every applicant who searches and registers on the agency’s own website rather than solely through the portals is a contact the agency owns directly. The portals charge for that relationship. The agency’s own site delivers it for free, indefinitely, if the experience is good enough to compete.
Page Speed
Load time was reduced from five point eight seconds to one point four. This involved a combination of image compression and lazy loading for property photography, a move to a faster hosting environment, proper caching implementation and removing several legacy scripts that had been added over the years and never removed when they stopped being needed. The improvement in Google search rankings that followed was noticeable within six weeks — page speed being one of the factors Google uses to determine which sites deserve prominent placement in local search results.
Conversion Points
The valuation request form was redesigned and repositioned. Instead of being buried in the navigation, a valuation CTA appeared on the homepage above the fold, on every property listing page and in a persistent banner on area guide pages. The form itself was reduced to three fields for the initial submission — address, property type, contact details — with additional information collected in the follow-up call. The number of valuation requests submitted through the website in the first month after launch was four times the monthly average of the previous year.
Rental applicant registration was similarly streamlined. A clear, simple registration form with an explanation of what happens after submission — the kind of basic reassurance that most agency websites do not bother to provide — replaced a generic contact form that gave no indication of what the process looked like or how quickly someone would be in touch.
Content
The area guides were completely rewritten. Not just updated — rewritten from scratch by someone with genuine knowledge of the areas involved, covering the things that people making relocation decisions actually want to know. School catchment areas. Commute times on specific lines. Which streets offer the best value. Where the independent coffee shops are versus the chains. The kind of hyper-local, genuinely useful information that a portal cannot provide and that a good local agent is actually well placed to offer.
This content did something the old guides never managed — it ranked. Within three months, several of the new area guide pages were appearing on the first page of Google results for searches like “living in Clapham” and “best streets in Balham” — the kind of searches made by people at the research stage of a move who are not yet registered with any agent. Capturing that audience before they reach the portals is exactly what good estate agency content should do.

The Results — April to September 2025
The numbers across the six months following launch told a clear story. Sales instructions — new properties taken on for sale — were up thirty-one percent compared to the same period in 2024. Rental instructions were up twenty-two percent. Combined, the increase across both departments came to just over twenty-five percent.
Valuation requests through the website specifically increased by over three hundred percent, though it is worth noting that not all of those converted to instructions — conversion rate from valuation to instruction remained broadly consistent with historic levels. The website was generating significantly more top-of-funnel activity. What the team did with those enquiries was down to them.
Direct website applicant registrations — people registering their requirements on the Hartley & Cross site rather than solely through the portals — increased by one hundred and forty percent. That is a material shift in the agency’s relationship with its applicant database and has ongoing value well beyond the six-month measurement period.
Caroline, the senior partner who had been the most sceptical voice at the start of the project, put it simply when we spoke in October. “We thought the website was fine,” she said. “It wasn’t fine. It was costing us business every single day and we had no idea.”
The Wider Lesson For Estate Agents
Hartley & Cross are not unusual. The pattern — a functioning but underperforming website, a reliance on portal traffic that masks how much business the site itself is losing, a gradual accumulation of content that was once useful and has quietly become a liability — is extremely common among independent estate agents of a certain vintage.
The portals are not going anywhere and they are not getting cheaper. In that environment, an estate agency website that converts well, ranks well and builds a direct relationship with applicants and vendors before they find their way to Rightmove is not a nice-to-have. It is a competitive necessity. The agencies that understand that in 2025 are the ones that will be best positioned when the market eventually does whatever unexpected thing it does next.
Frequently Asked Questions
Can an estate agency website really compete with Rightmove and Zoopla for property search traffic?
Not for volume — the portals have audiences and domain authority that no independent agency website will match for generic property search terms. But that is not the right competition to be entering. A well-optimised independent agency website can compete very effectively for hyper-local search terms — specific streets, neighbourhoods and area queries — where the portals’ generic content is weaker and where genuinely local expertise, properly expressed in well-written content, can outperform them. That is a more achievable and commercially valuable target than trying to out-Rightmove Rightmove.
How important is property photography to an estate agency website’s performance?
Enormously important — but in two distinct ways that are often conflated. The quality of the photography affects how appealing listings look and how long visitors spend engaging with them. The technical handling of the photography affects how fast pages load, which affects both search rankings and the proportion of visitors who stay long enough to enquire. Both matter. Most estate agency website projects need to address both — investing in better photography while also making sure that photography is displayed in a way that does not destroy page performance.
Should an independent estate agent invest in their own website or focus their budget on portal listings?
Both, ideally — but the framing of the question as either/or is worth examining. Portal spend is largely non-negotiable for most agents; the listings need to be there. But portal spend is also a cost that produces no compounding return — you pay, you get visibility, you stop paying and the visibility stops. A well-built agency website, by contrast, builds search equity over time, owns the relationship with registered applicants directly and reduces long-term dependency on platforms whose pricing is entirely outside the agency’s control. The two are not in competition. They serve different functions and a well-run agency needs both working properly.
NB: ‘Hartley & Cross’ is not the actual name of the client, due to NDAs, we cannot name the actual clients that we work with unless they agree.
