The verdict in three sentences
For a London main contractor, an effective website costs between 10,000 and 18,000 GBP and goes live in 6 to 8 weeks. Its value comes from geolocated project case studies, verifiable CHAS and Constructionline accreditations and a careers page able to attract the site operatives you are short of. Built well, it can bring in around a quarter of developer enquiries, which pays it back with the first package won.
What developers and private clients look for
A developer preparing a tender for a 40-unit residential scheme in Croydon or Stratford shortlists three to five contractors. Before calling, the project manager checks three things online: delivery capacity (headcount, plant, turnover), comparable completed schemes and accreditations. A website that shows these in under two clicks passes the first filter. A generic five-page brochure with no photos of formwork or concrete pours gets dropped.
The pages that convert are proof pages: one case study per project with borough, structure type (frame, basement, RC walls), floor area, indicative package value and the client when they agree to be named. Geolocated on a map of Greater London, they also capture local searches such as concrete frame contractor Enfield.
| Page | Expected content | Goal | Share of budget (2026 estimate) |
|---|---|---|---|
| Home | Key figures, area covered, tender call to action | Qualify in 10 seconds | 12 % |
| Projects | 15 to 25 geolocated case studies with photos | Prove capacity | 30 % |
| Accreditations | CHAS, Constructionline, insurance, ISO certificates | Reassure the buyer | 8 % |
| Capabilities | Frames, basements, piling, refurbishment | Position the firm | 12 % |
| Careers | Vacancies, pay, progression, 2-minute application | Hire operatives | 20 % |
| Tender contact | Form with tender document upload | Receive invitations to tender | 10 % |
| Local SEO and tracking | Google profiles, schema, analytics | Measure enquiries | 8 % |
Budget, timeline and maintenance: three realistic levels
Price depends mainly on how many case studies need writing and how good the existing photography is. A photo and drone shoot on three live sites often adds 1,500 to 2,500 GBP, yet it remains the most profitable investment of the project.
| Level | Scope | 2026 price (ex VAT) | Timeline | Maintenance |
|---|---|---|---|---|
| Essential | 8 pages, 10 case studies, contact form | 10,000 GBP | 5 weeks | 120 GBP/month |
| Standard | 12 pages, 20 geolocated projects, careers page | 14,000 GBP | 6 weeks | 120 GBP/month |
| Advanced | Standard + tender upload, candidate portal, 2 languages | 18,000 GBP | 8 weeks | 200 GBP/month |
| Photo and drone option | 3 sites, 60 edited visuals | 1,500 to 2,500 GBP | 2 weeks | n/a |
| Recruitment video option | 90-second film with operatives | 2,000 to 4,000 GBP | 3 weeks | n/a |
| Monthly local SEO | Google profiles, 2 project posts a month | 400 to 800 GBP/month | ongoing | included |
Maintenance at 120 GBP a month covers hosting, security updates, backups and one small change per month. New case studies can be added in-house if the content editor is simple: a project page should be publishable in 15 minutes from a phone.
The careers page, an underrated lever
With a shortage of formwork carpenters, steel fixers and foremen, the website also becomes a hiring tool. Construction candidates browse mainly on mobile, often in the evening. They want pay, project types, commute and progression. A page that shows a pay range, for instance 220 to 280 GBP a day for an experienced formwork carpenter depending on CSCS card and experience, receives noticeably more applications than an advert with no figures.
The form should fit in four fields with an optional CV upload. A direct WhatsApp button to the site manager or HR removes another barrier.

Tom, managing director of a 70-person main contractor in London, invests 14,000 GBP in the Standard level plus 2,000 GBP of photography, so 16,000 GBP. Maintenance: 120 x 12 = 1,440 GBP a year. First-year cost: 17,440 GBP.
Over 12 months the site generates 25 tender invitations, about a quarter from developers (6 contacts). He wins a 650,000 GBP frame package at a 5 % net margin, so 32,500 GBP. That single project repays the site almost twice. On hiring, 4 operatives recruited through the careers page avoid roughly 4 x 3,000 GBP of agency fees, so 12,000 GBP saved.
FAQ
How much does a website for a London contractor cost in 2026?
Budget 10,000 to 18,000 GBP depending on the number of case studies and features. The most popular level, with 20 geolocated projects and a careers page, sits around 14,000 GBP.
Should CHAS and Constructionline accreditations appear on the site?
Yes, with membership numbers and links to the official registers. Private buyers check them every time, and an up-to-date accreditations page cuts document exchanges during pre-qualification.
How many project case studies should we publish?
Aim for 15 to 25, prioritising schemes from the last three years. Each page should show the borough, structure type and an indicative floor area or value.
Can the website really help with recruitment?
Yes, if the careers page shows pay, projects and progression. A contractor hiring 4 operatives a year through the site saves around 12,000 GBP in agency fees.
How long until launch?
Six weeks for the Standard level, two of which go into gathering case studies and photos. Delays almost always come from content, rarely from development.
