The verdict in three sentences
Against national networks, an independent building control and inspection firm wins work on responsiveness, local presence and a clear offer, and its website is often the client's first filter. It must show on one page its registrations with the Building Safety Regulator, the services offered (building control, fire safety, structural review, accessibility, energy) and the building types covered, then accept a service request with file uploads answered within 48 hours. One inspection appointment on a residential scheme pays for the website several times over.
How a developer chooses an inspection firm
The managing director of a 30-engineer firm in London serves three audiences with different expectations. The developer wants a fee and a fast start date to satisfy the funder and the warranty provider. The housing association buys through frameworks and looks at comparable references. The borough uses public procurement and requires certificates, CVs of the inspectors and a methodology. Since the Building Safety Act, higher-risk buildings go through the Building Safety Regulator gateways, which makes demonstrable competence a selling point.
| Service | Scope | Typical fees (2026 estimate, GBP) | Typical building |
|---|---|---|---|
| Building control (RBI) | Plans and site inspections | 5,000 to 30,000 | Residential blocks, offices |
| Fire safety review | Fire strategy, compartmentation | 6,000 to 35,000 | Schools, care homes |
| Gateway support for HRBs | Gateway 2 and 3 submissions | 15,000 to 60,000 | Buildings over 18 m |
| Structural review | Independent check | 3,000 to 15,000 | Extensions, conversions |
| Accessibility audit | Part M compliance | 2,000 to 10,000 | Public buildings, new homes |
| Energy and Part L | SAP and SBEM checks | 2,500 to 14,000 | New build, deep retrofit |
| Full package | Complete project | 20,000 to 75,000 | School, mixed-use scheme |
Publishing fee ranges is not mandatory, but showing what drives them (floor area, number of visits, programme length) builds trust and reduces unqualified enquiries.
The pages that generate service requests
The site is organised by building type rather than regulatory jargon: residential, offices, education, healthcare, industrial, refurbishment. Each page cites two or three London references with floor area, duration and services delivered. An 'Accreditations and insurance' page gathers the RBI registration, professional indemnity certificate and CABE or RICS memberships, documents that public buyers always ask for.
The request form is the core of the system: project type, floor area, start date, services needed, then upload of drawings and the design and access statement. A complete file means a fee proposal in 48 hours instead of a week of back and forth.
| Kolonell tier | Budget | Typical scope | Timeline |
|---|---|---|---|
| Starter | 1,220 to 1,830 EUR | Service pages, accreditations, contact | 6 weeks |
| Growth | 1,830 to 3,050 EUR | Pages by building type, references, form with file uploads | 7 weeks |
| Premium | 3,050 to 5,340 EUR | Client portal for reports, downloadable framework kit, CRM | 8 weeks |
| Maintenance | 53 to 183 EUR per month | Security, backups, updates | Monthly |
| Monthly SEO | 100,000 to 350,000 FCFA per month | Queries such as 'building control London', service pages | Monthly |
A London agency typically charges 10,000 to 30,000 GBP for a comparable scope, as a 2026 order of magnitude.
Public frameworks and boroughs
For boroughs, the website does not replace the tender portal, but it weighs on the quality score. A buyer checking your site should find the same methodology, the same references and the same names as in your bid. A downloadable kit (company profile, certificates, standard CVs) saves your bid manager time on every tender.

Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Daniel, managing director of a 30-engineer inspection firm in London, receives 6 enquiries a month through his old site, half of them incomplete. He moves to Growth for 2,900 EUR and 75 EUR per month of maintenance. Six months after launch, the form produces 14 enquiries a month, 10 of them complete. With a 25 % conversion rate and an average fee of 12,000 GBP, that is 2.5 appointments a month, or 30,000 GBP. Compared with 1.5 appointments a month before, the gain is one extra appointment a month, about 12,000 GBP, against a yearly website cost of 2,900 + 12 × 75 = 3,800 EUR.
FAQ
Should we publish our fees online?
Not fixed prices, but ranges per service and the factors behind them. That cuts out-of-scope enquiries by around 30 %, as an order of magnitude.
How are client drawings kept secure?
Files are stored outside public access, with expiring links and automatic deletion after 90 days if the appointment is not signed. Premium adds an authenticated client portal.
Does the site help win public frameworks?
It does not replace the bid, but it confirms it. An up-to-date framework kit saves your bid manager 1 to 2 hours per tender.
How many references should we show?
Three per building type is enough, 15 to 20 in total. State floor area, services and duration, with the client's approval.
How long until the site is live?
Plan 6 to 8 weeks depending on the tier, including one week of writing service pages with your engineers.
