The verdict in three sentences
An acoustic consultancy wins its best commissions when it is appointed at RIBA Stage 2, before the developer or venue operator has locked in construction choices. The website must prove expertise per service type (Approved Document E pre-completion testing, noise impact assessment, room acoustics) with measured results in dB. A Growth website at around EUR 2,500 (about GBP 2,150), delivered in 6 weeks, pays for itself with two residential sound testing contracts.
The services that need their own page
A developer searching "pre-completion sound testing London" does not want a generic homepage. They want to know whether you cover their type of scheme, how fast and for what budget. Each service deserves a dedicated page with its regulatory framework, its deliverable and a fee range.
| Service | Main client | Fees (2026 order of magnitude) | Turnaround |
|---|---|---|---|
| Approved Document E pre-completion testing | Developers, housing associations | GBP 2,200 to 7,800 | 1 to 3 weeks after testing |
| Noise impact assessment (planning) | Bars, music venues, nightclubs | GBP 2,600 to 10,500 | 3 to 6 weeks |
| Room acoustics and sound insulation design | Cinemas, auditoriums, studios | GBP 7,000 to 30,000 | 6 to 12 weeks |
| Schools and nurseries acoustics (BB93) | Local authorities, public clients | GBP 4,300 to 21,500 | 4 to 10 weeks |
| Full design team acoustic consultancy | Commercial developers, REITs | GBP 17,000 to 52,000 | Whole project duration |
| Neighbour noise surveys and expert witness | Managing agents, solicitors, insurers | GBP 1,300 to 5,200 | 1 to 3 weeks |
Each page should cite the reference documents (Approved Document E, BB93, BS 8233, BS 4142), show an anonymised sample deliverable and carry a request-for-proposal button.
Case studies that convince developers
Developers and venue operators buy an avoided risk: a failed completion test, residents' complaints, a licence review. Your case studies must quantify the result. A page titled "600-seat venue in Hackney: noise breakout cut from 9 dB(A) to 2.5 dB(A)" is worth more than ten paragraphs of company profile.
| Kolonell level | Starter | Growth | Premium |
|---|---|---|---|
| Indicative price | EUR 1,220 (800,000 FCFA) | EUR 1,830 to 3,050 | EUR 3,050 to 5,340 (3,500,000 FCFA) |
| Service pages | 3 pages | 6 detailed pages | 6 pages + pages per venue type |
| Case studies | 2 cases | 8 cases with dB measurements | Database filterable by service and borough |
| Proposal form | Simple | Drawing upload and RIBA stage | Upload + budget and timing qualification |
| Regulatory blog | No | 1 article a month at launch | 6-month editorial calendar |
| Local SEO London and South East | Optimised Google profile | Pages per area | Pages per area + per building type |
| Lead time | 4 weeks | 5 weeks | 6 weeks |
For 12 engineers, Growth is enough if residential work dominates. Premium becomes relevant if you target venues and full design team appointments, where a single commission often exceeds GBP 26,000.
Getting appointed at Stage 2
The decisive moment is concept design. That is when an acoustician can prevent an expensive lining upgrade or a poor floor build-up. Your website should say so clearly, with a "Why appoint us at Stage 2" page, a comparison of remedial cost on site versus design-stage input, and a pre-assessment offer at GBP 780 deductible from the full commission. This kind of entry offer converts two to three times better than a plain contact form.

Nadia, managing director of a 12-engineer acoustic consultancy in London, delivers about 70 commissions a year at an average fee of GBP 6,700. She picks the Premium level at EUR 5,340. Within nine months, the website generates 46 qualified proposal requests, 14 of which are signed: 4 venue projects at GBP 15,500 on average and 10 sound testing contracts at GBP 3,900, totalling GBP 101,000 of new revenue. The website costs less than 5% of that amount.
FAQ
Should we show fee ranges on the website?
Yes, broad ranges reassure buyers and filter out-of-budget requests. Stating "sound testing from GBP 2,200" cuts unqualified enquiries by roughly 30%.
Do developers really look for acousticians on Google?
Large housebuilders have panels, but regional developers, housing associations and venue operators search online. Queries around "sound testing" generate thousands of monthly searches in the UK.
How do we show measurements without naming clients?
Anonymise the scheme (type, borough, floor area) and publish before and after values in dB. A simple chart is enough to demonstrate a 6 to 10 dB gain.
Can the site handle urgent requests?
Yes, a dedicated button for urgent cases (complaint, abatement notice) can trigger an SMS alert to the on-call engineer. These requests often sign within 48 hours.
How long until we rank on Google?
Allow 3 to 6 months for solid positions on local queries. A monthly regulatory blog clearly speeds up visibility growth.
