Engineering and construction firm website cost in Bath: local agencies vs Kolonell (2026)

The verdict in three sentences

In Bath, an engineering and construction firm website costs, as a 2026 ballpark, 6 000 to 25 000 GBP with a local agency, and often 12 000 to 40 000 GBP with one of the larger Bristol agencies that serve the South West. Kolonell builds the services, projects, prequalification and careers pages of a contractor or consultancy for a fixed 2 300, 3 900 or 6 900 GBP, delivered in 3 to 4 weeks on Starter and Growth. In a city where most work touches World Heritage constraints and Bath stone, the site has to prove care on sensitive sites; the price gap matters most when you also budget photography and copy over three years.

Bath agency, Bristol agency, freelancer or Kolonell: who charges what?

Bath has a small but solid pool of studios, and many construction firms in the city also ask Bristol agencies to pitch. The ranges below are prudent orders of magnitude based on public rate cards of agencies in Bath and Bristol, minimum project sizes on Clutch.co profiles, hourly rates published by South West agencies (often 65 to 120 GBP per hour) and freelance rates visible on Upwork.

To be fair to local suppliers: a Bath freelancer can match or beat the Kolonell Starter price. What Kolonell adds is a project manager on your time zone (the team is in Senegal, GMT, so on Bath time in winter and one hour behind in summer), Google Meet calls at your hours, a written update every week, a fixed price for a written scope, and the domain and all access in your name. Details are on our international website offer.

Where does the money go over three years?

A contractor's site needs regular feeding: completed schemes, new frameworks won, new vacancies, renewed accreditations. Maintenance after Kolonell's support period is quoted on request, so the table uses the same maintenance assumption on both sides.

This is a framework for comparison, not a forecast. Hand the same table to each bidder.

What does a design-and-build contractor in Bath need to show?

The whole city of Bath is inscribed as a UNESCO World Heritage Site, and much of it sits in a conservation area, so commissions often involve listed Georgian terraces, Bath stone repair, discreet extensions and careful logistics on narrow streets. Around it, the market includes schools, housing schemes and commercial work across Bath and North East Somerset, Wiltshire and the Bristol area. Clients want evidence that you can deliver on a sensitive site without disrupting neighbours.

• Services: design and build, main contracting, refurbishment, structural and civil engineering, temporary works, according to what you actually do.
• Project sheets with scope, programme, constraints and your role, only with the client's agreement; anonymised when needed.
• Site management: how you handle logistics, neighbours and heritage fabric; Considerate Constructors Scheme registration only if you hold it.
• Health and safety: CDM 2015 duties as principal contractor or designer; CHAS, Constructionline or other SSIP accreditations only if held; ISO 9001, ISO 14001, ISO 45001 only if certified.
• Public sector readiness: a capability statement and policies to download, since public contracts are advertised on Find a Tender and Contracts Finder.
• People: Chartered Engineers or chartered builders only where true, site managers, and a real careers section for apprentices and graduates.

Which tier fits a contractor after a merger?

A subcontractor portal, site diary software, an ERP or BIM integration is a custom application, quoted on request; so is ongoing search work. Kolonell does not shoot on site and holds no physical meetings. It has not built an engineering site before; its public references are a notary group in New Jersey and a property consultancy in Dubai.

Which warning signs should stop you?

• A quote for a merger rebrand that says nothing about redirects from the two old domains.
• Galleries of uncompressed drone images: Bath clients often check sites on a phone between meetings.
• No clause on photo licences for the images taken by your site photographer.
• Projects published without client sign-off.
• Accreditation logos added by default without checking you hold them.
• Domain and hosting held by the supplier.

Mini case study

Illustrative example. Gareth L., managing director of a 60-person design-and-build contractor in Bath, has just merged with a small civils firm from the Bristol side and needs one brand within two months. A Bristol agency quotes 26 000 GBP over 14 weeks; a Bath agency quotes 12 500 GBP over 10 weeks. Kolonell proposes Premium at 6 900 GBP with a written schedule of 5 weeks.

Gareth adds 2 400 GBP of licensed photography to each option and 300 GBP for redirect testing. Totals: 28 700 GBP, 15 200 GBP and 9 600 GBP. He picks Premium because the merger deadline matters more than workshops, and he keeps the local photographer he already uses.
