The verdict in three sentences
A website for a commercial refrigeration and HVAC contractor in London costs GBP 6,000 to 12,000 and ships in 6 to 8 weeks. It must do three precise things: sell maintenance contracts to supermarkets and warehouses, capture emergency callouts and attract refrigeration engineers in a market where every hire is contested. A realistic goal is 5 to 10 contract enquiries a month after 6 months of search visibility.
The structure of a site that sells contracts
The managing director of a London contractor with 30 engineers works on cold rooms, supermarket display cabinets, CO2 pack systems and commercial air conditioning across Greater London and the Home Counties. Buyers are store managers, logistics warehouse maintenance leads and facilities managers. They want sector references, guaranteed response times and certifications (F-Gas, REFCOM).
| Element | Sales role | Indicative 2026 budget (GBP) |
|---|---|---|
| Sector pages | Grocery retail, logistics, food processing, offices, healthcare | 1,300 to 2,600 |
| Maintenance contract pages | Tiers, visit frequency, response times | 850 to 1,700 |
| Contract request form | Number of units, floor area, capacity, site | 700 to 1,500 |
| 24/7 emergency block | On-call number, quick form, callback within 30 min | 450 to 1,000 |
| Careers section | Engineer vacancies, 2-minute mobile application | 700 to 1,500 |
| References and certifications | Case studies, client logos, accreditations | 600 to 1,300 |
| Local and technical SEO | London boroughs, Kent, Surrey, Essex, Google profiles | 850 to 1,700 |
| Lead tracking | Dashboard, CRM or structured email integration | 600 to 1,300 |
Three website levels
| Level | Price (GBP) | Content | Timeline |
|---|---|---|---|
| Essential | 6,000 to 7,300 | 10 to 12 pages, 3 sectors, contract form, emergency, jobs | 6 weeks |
| Growth | 7,700 to 9,800 | 18 to 22 pages, 5 sectors, 4 case studies, multi-area local SEO | 7 weeks |
| Performance | 10,300 to 12,000 | 25+ pages, contract calculator, simple client area, connected CRM | 8 weeks |
After launch, plan GBP 100 to 215 a month for maintenance and GBP 350 to 770 a month if you want SEO support to rank for "cold room maintenance London" or "warehouse air conditioning contractor".
What maintenance contracts are worth
| Client type | Average annual contract (GBP) | Enquiry conversion rate | Average term |
|---|---|---|---|
| Convenience store | 3,000 to 6,000 | 25 to 35% | 3 years |
| Superstore | 10,000 to 26,000 | 10 to 20% | 3 to 5 years |
| Cold-chain logistics warehouse | 13,000 to 38,000 | 10 to 15% | 3 to 5 years |
| Restaurant or bakery | 800 to 2,100 | 35 to 50% | 2 years |
| Office (air conditioning) | 1,700 to 6,800 | 20 to 30% | 3 years |
These 2026 orders of magnitude show that a single warehouse contract can pay for the site. The site also serves recruitment: a clear careers page with salaries shown (GBP 38,000 to 52,000 a year for an experienced refrigeration engineer in London, plus on-call pay) noticeably lowers cost per application.
Mini case study
Steve, managing director of a commercial refrigeration firm in London, invests GBP 9,000 in a Growth-level site. After 6 months he receives 7 contract enquiries a month. With an average 20% conversion rate, he signs about 1.4 contracts a month at GBP 5,100 a year on average. Over 12 months that is nearly 17 contracts and GBP 86,000 in annual recurring revenue. On the hiring side, he drops a GBP 400 a month paid job ad and hires 2 engineers through the careers page. The site pays for itself by the second signed contract.
