The verdict in three sentences
An electronics component maker serves two audiences with opposite needs: the design engineer, who wants to filter 300 to 3,000 parts by parameter and download a datasheet and 3D model in under a minute, and the buyer or distributor, who wants accurate stock, compliance documents and clean data. A good specification turns those needs into measurable requirements that agencies can price like for like. Realistic 2026 budget: GBP 14,000 to 50,000, 10 to 18 weeks, plus GBP 1,600 to 5,500 a year for support.
Specification template, section by section
| Section | What to write | Example measurable requirement |
|---|---|---|
| 1. Context and goals | Company, markets, numeric targets | 40 qualified sample requests a month within 12 months |
| 2. Audiences | Design engineers, buyers, distributors, press | 3 journeys described with their top 5 tasks |
| 3. Catalogue and parametric search | Families, filterable parameters, volume | 1,200 parts, 8 to 15 filters per family, results under 1 s |
| 4. Technical documents | Datasheets, 3D models, CAD footprints | STEP and PDF download in one click, versioned |
| 5. Compliance | UKCA, CE, RoHS, REACH declarations | Declaration of conformity linked on every relevant part page |
| 6. Data and integrations | ERP or PIM, frequency, fields | Nightly sync, zero obsolete parts displayed |
| 7. Distributor stock links | Which distributors, how | Live "buy from distributor" links per part |
| 8. Performance and accessibility | Speed, standards | Mobile load under 2.5 s, WCAG 2.2 AA |
| 9. Security and privacy | Hosting, UK GDPR, PECR | Consent before any non essential cookie |
| 10. Vendor selection criteria | Weighting | Price 30 %, method 30 %, references 25 %, support 15 % |
The core: catalogue, compliance and data
Parametric search is the feature that costs and pays. For a DC to DC converter, an engineer filters by input voltage, output current, package and temperature range; for a sensor, by measured quantity, accuracy and interface. List every family with its parameters, units and type (range, list, boolean).
Compliance needs its own section in the UK. Products placed on the GB market generally carry UKCA marking, while CE marking continues to be accepted for many product categories; your site should link the right declaration of conformity to each part, alongside RoHS and REACH statements. Decide the source of truth too: if data lives in the ERP, the site syncs from it; if it is enriched in a PIM, the PIM feeds both the site and distributor feeds.
| Volume and integration | 2026 budget (GBP excl. VAT) | Timeline |
|---|---|---|
| 300 parts, scheduled manual import | 14,000 to 20,000 | 10 to 12 weeks |
| 300 to 1,000 parts, nightly ERP export | 20,000 to 32,000 | 12 to 14 weeks |
| 1,000 to 3,000 parts, PIM connector | 32,000 to 50,000 | 14 to 18 weeks |
| Distributor stock and buy links | 2,500 to 7,000 extra | Plus 1 to 2 weeks |
| Compliance document library | 1,500 to 4,000 extra | Plus 1 week |
| Annual support | 1,600 to 5,500 | Per year |
Requirements that prevent surprises
Write numeric acceptance criteria: filter response under 1 second with 3,000 parts, 100 % of datasheet links valid, no more than 24 hours between an ERP change and the live site. Require source code handover, integration documentation and a staging environment. Ask every agency to answer section by section using your numbering: comparing proposals then takes half a day instead of a week.
Mini case study
Illustrative example: Tom, marketing manager at a 120-person power electronics maker in west London, specifies 1,300 parts across 8 families, synced nightly from the ERP, with distributor stock links. He gets 4 proposals between GBP 28,000 and 47,000 and picks one at GBP 34,000 with GBP 3,200 a year of support.

The maths: three-year cost of GBP 43,600. If sample requests rise from 15 to 38 a month and one in thirty becomes a production design win worth GBP 20,000 a year, that is roughly 27 extra design wins over three years.
FAQ
What does an electronics component maker website cost in London?
GBP 14,000 to 50,000 in 2026 depending on part count and ERP or PIM integration. Add GBP 1,600 to 5,500 a year for support.
How many parametric filters should we plan?
Usually 8 to 15 per product family. Beyond that, the interface gets hard to use on mobile and engineers only touch the first five.
Do we need both UKCA and CE documents online?
If you sell into Great Britain and the EU, publishing both declarations where applicable avoids repeat requests from buyers. A document library costs about GBP 1,500 to 4,000 to set up.
What timeline should we expect?
Ten to 18 weeks. Cleaning product data often takes 2 to 4 weeks on its own.
