The verdict in three sentences
For an Oxford agency selling to international buyers and second-home owners, relying on Rightmove and Zoopla alone is cheap in year 1 but leaves you without area pages, owned enquiries or a place to explain how buying in England works. Over 3 years, a typical local agency redesign comes to roughly £20,400 in our model (build plus market maintenance assumptions), against about £7,200 with Kolonell Growth at £3,900 or £10,200 with Premium at £6,900, the portal or CRM feed being on quote in every scenario. The redesign pays off only if the migration is handled with care: a full URL inventory, a deliberate plan for sold listings, and a 301 map for every area page that already ranks.
Portal-only or your own website: what does each cost over 3 years?
Build prices reflect typical Oxford and London agency quotes and public rate pages (2026 ballpark). Maintenance figures are market assumptions for hosting, updates and small changes, not Kolonell prices: Kolonell includes 3 months of support, and maintenance afterwards is on quote. Portal subscriptions, photography and the listings feed are left out because they apply to every scenario or are scoped separately.
| Scenario | Year 1 | Year 2 | Year 3 | 3-year total |
|---|---|---|---|---|
| Portal-only plus a freelance holding page (£1,500 build, £300 a year assumed) | £1,800 | £300 | £300 | £2,400 |
| Freelance redesign (£5,000 build, £1,200 a year assumed) | £6,200 | £1,200 | £1,200 | £8,600 |
| Oxford or London agency redesign (£15,000 build, £1,800 a year assumed) | £16,800 | £1,800 | £1,800 | £20,400 |
| Kolonell Growth (£3,900, then £1,200 a year assumed from month 4) | £4,800 | £1,200 | £1,200 | £7,200 |
| Kolonell Premium (£6,900, same assumption) | £7,800 | £1,200 | £1,200 | £10,200 |
In year 1 for the Kolonell rows, 9 months of assumed maintenance (9 x £100 = £900) are added because the first 3 months of support are included. Premium is the multilingual tier, with languages set in the quote, which suits agencies whose buyers arrive from abroad. Full scope is on the international offer page.
What does a portal-only presence leave on the table?
| Capability | Portal-only | Own redesigned site |
|---|---|---|
| Area guides for North Oxford, Summertown, Boars Hill, Cotswold villages | Not possible | Pages you own and update |
| Guidance for overseas and second-home buyers | Not possible | Buying process page, reviewed for accuracy |
| Vendor valuation requests | Mixed with portal leads | Dedicated form and page |
| Ownership of enquiry data | Shared with the portal | Held by the agency under UK GDPR |
| Sold archive and track record wording | Disappears when the listing ends | Kept deliberately, without invented figures |
| Redress scheme and agency details | Limited space | Clear footer and about page |
Every UK estate agent must belong to a redress scheme, either The Property Ombudsman or the Property Redress Scheme, and listings must give buyers the material information consumer protection law requires. Your own site lets you present both clearly. Area pages describe colleges, schools, rail links to London and the character of streets in general terms; they should never quote invented price levels or averages.
What timeline and which risks should you plan for?
Once content is ready, Kolonell delivers in 3 to 4 weeks: audit and URL inventory in week 1, design in weeks 1 to 2, build and migration in weeks 2 to 3, compliance review, redirects and launch in weeks 3 to 4. A local agency usually plans 10 to 14 weeks. The main bottleneck is the agency's own content: area descriptions, team bios and the buying guide.
| Risk | Likelihood | Mitigation |
|---|---|---|
| Area pages lose rankings | High without a plan | Export URLs from Search Console, 301 map, 8 weeks of monitoring |
| Sold listings become 404 errors | High | Keep as status pages or redirect to the area page |
| Portal feed not ready on launch day | Medium | Launch with links to portal listings, switch when the feed is live |
| Enquiry forms collect too much personal data | Medium | Name, contact, property reference, optional budget range only |
| Cookie banner breaches PECR | Medium | Consent before analytics and ad pixels, per ICO guidance |
| Site fails accessibility checks | Medium | WCAG 2.2 AA target, keyboard and contrast tests |
Under UK GDPR and the Data Protection Act 2018, open web forms are no place for ID documents or proof of funds; anti-money-laundering checks on buyers are part of the agency's own process. The Equality Act 2010 expects reasonable adjustments, which WCAG 2.2 AA helps you demonstrate. This is not legal advice.
What stays on quote, and what should you ask?
The Rightmove, Zoopla or property CRM feed, any vendor portal, valuation tools and custom applications stay on quote. Photography, video tours, drone footage and floor plans are third-party costs paid to a local photographer. Ask each provider: Who builds the 301 map and checks it after launch? How are sold listings handled? Can the site go live before the feed? Who owns the domain and analytics? What does maintenance cost after the included period?

A local agency fits if you want face-to-face workshops, a combined brochure and signage package, or a complex feed tied to an in-house system that needs on-site support. It also fits a budget above £15,000 where brand strategy is part of the brief. For a fixed-scope redesign with a clear migration plan, a remote studio is often the more economical route over 3 years.
Mini case study
*Illustrative example, fictional agency.* Harriet runs Isis Meadow Homes, an Oxford agency whose buyers are often relocating families from abroad and Londoners looking for a second home in the Cotswolds. She has relied on portals only for two years. Using the model above, a local redesign comes to £20,400 over 3 years and Kolonell Premium to £10,200, a gap of £10,200. She keeps £2,000 of that gap for photography and floor plans (third-party costs), and the feed is quoted separately. The inventory counts 46 old URLs: 22 area and guide pages redirected, 18 sold listings kept as status pages and 6 pages retired (22 + 18 + 6 = 46).
FAQ
Is a portal-only presence enough for an Oxford luxury agency?
It covers listings, but not area guides, vendor valuation pages or owned enquiry data. In our model it costs £2,400 over 3 years, the lowest figure, with the least control.
Why are maintenance figures labelled as assumptions?
Because they are market estimates for hosting and updates, not Kolonell prices. Kolonell includes 3 months of support and quotes maintenance afterwards.
How long does the redesign take?
3 to 4 weeks with Kolonell once content is ready, against 10 to 14 weeks for a typical local agency. Area descriptions are usually the slowest part.
Can we launch before the Rightmove or Zoopla feed works?
Yes. Many agencies launch with links to their portal listings and switch on the feed 2 to 4 weeks later, which keeps the redesign on schedule.
Should sold properties stay on the site?
Keep them as status pages or redirect them to the area page. Removing 18 sold URLs without redirects wastes the links they earned.
