The verdict in three sentences
For a luxury real estate agency in London, a website redesign costs between £3,900 and more than £60,000 as a 2026 ballpark, depending on whether you change only the design or also the property search, CRM feed and languages. The real risk is not the budget: it is losing traffic from area pages and existing listings, which feed your valuation requests. A redirect plan, a content inventory and eight weeks of post-launch monitoring shrink that risk to very little.
What budget should you plan for a redesign in 2026?
The ranges below are 2026 ballparks drawn from typical quotes by London agencies that specialise in property. They vary with the number of offices, the quality of the CRM feed and the number of languages.
| Redesign scope | Typical London agency quote | Kolonell | Indicative timeline |
|---|---|---|---|
| New design, same structure and feed | £8,000 to £20,000 | £3,900 (Growth) | 3 to 4 weeks |
| Full redesign with CRM feed (Reapit, Alto, Street) | £20,000 to £45,000 | £6,900 (Premium), API integration on quote | 4 to 8 weeks |
| Bespoke property search, maps, neighbourhoods | £35,000 to £70,000 | On quote | 8 to 14 weeks |
| Pages in 2 or 3 languages for overseas buyers | £4,000 to £12,000 | Native English or French copy included, other languages on quote | 1 to 3 weeks |
| Migration audit and redirect plan | £1,500 to £6,000 | On quote | 1 to 2 weeks |
| Refreshed photography, video and virtual tours | £3,000 to £15,000 | Booked with your usual suppliers | In parallel |
Kolonell plans under the international offer include a project manager reachable on London time, native copywriting, delivery in 3 to 4 weeks and 3 months of support. We built the website of Orven Properties, a real estate firm in Dubai, so the demands of an international buyer audience are familiar ground.
Which phases, and how long does each take?
A well-run redesign follows six phases. The durations below apply to an agency with one to four offices and 150 to 600 properties online.
| Phase | Duration | Deliverable | Main risk |
|---|---|---|---|
| Audit and traffic data | 1 to 2 weeks | List of pages that drive visits and enquiries | Missing the area pages that convert |
| Content and URL inventory | 1 week | Spreadsheet mapping old and new URLs | Sold or let listings deleted without redirects |
| Design and templates | 1 to 2 weeks | Home, property, area and valuation templates | Heavy galleries slowing mobile pages |
| Build and CRM feed | 2 to 4 weeks | Site on staging with live feed | Feed fields mismapped (price, status, tenure) |
| Testing and launch | 1 week | 301 redirects live, forms tested | Valuation forms no longer reaching the right negotiators |
| Post-launch monitoring | 4 to 8 weeks | Weekly Search Console and enquiry report | Undetected drop on area searches |
Which risks hurt prime agencies most?
The first risk is losing area pages. A page ranking for flats for sale in Belgravia or houses in Hampstead often brings more vendor enquiries than the home page. If its URL changes without a redirect, that ranking can vanish for weeks.
The second is sold and let listings. Many agencies delete them during a redesign, yet these pages earn links and prove your activity on a specific street. Keep them with a sold status or redirect them to the area page.
The third is the CRM feed. Rightmove, Zoopla and OnTheMarket are usually fed straight from your CRM rather than from the website, but the site often reads the same feed. One mismapped field can show the wrong status or a price that conflicts with the portals. Agents should also follow National Trading Standards guidance on material information in listings (price, tenure, council tax): check that the new property template still shows it.
Then come off-market properties, often reserved for registered buyers, where access must stay protected. Finally, compliance: UK GDPR for valuation and registration forms, and PECR rules for cookies and tracking. This is not legal advice.

- Test the CRM feed on 20 real properties before launch.
- Route each valuation form to the right office and negotiator.
- Keep the old site available on a private environment for 30 days.
- Launch on a Tuesday or Wednesday, never before a weekend of viewings.
Mini case study
Illustrative example: Charlotte runs a prime agency with three offices in Chelsea, Kensington and Hampstead. Her site gets 9,000 organic visits a month with a 1.2% enquiry rate, about 108 enquiries monthly. A 30% drop for three months would cost around 97 enquiries. If 2% of those become sales instructions at an average fee of £30,000 (1.5% of a £2 million home), the shortfall approaches £58,000. Against that, a £1,500 to £3,000 redirect plan is cheap insurance. She chooses a Premium redesign at £6,900, adds the migration audit and keeps the existing property search for a second phase.
FAQ
How long does a prime agency website redesign take?
Plan 6 to 10 weeks in total including audit and monitoring, of which 3 to 4 weeks are design and build with Kolonell. A bespoke property search usually adds 4 to 8 weeks.
Will we lose traffic after the redesign?
A 5 to 15% fluctuation for a few weeks is common even with good redirects. A lasting loss above 30% almost always points to unredirected URLs or deleted content.
Should sold listings stay online?
In most cases yes, with a sold or let status, or redirected to the area page. An agency with 300 sold properties online keeps pages that prove its activity street by street.
Should we change CRM at the same time?
It is not advisable: changing CRM and website together doubles the risk on the listings feed. Keep the two projects at least 2 to 3 months apart.
Does the site need to be multilingual?
If more than 20% of your buyers come from abroad, key pages in 2 or 3 languages are justified. Start with the home page, area guides and contact form rather than translating every listing.
