Electrical installation businesses in Castellón: buying, selling and valuation
Electricians share a statistic with a large part of the building trades. The INE (Spanish National Statistics Institute) does not break down electrical installation by province, so the figure available is that of the specialised construction division: 2,597 establishments in Castellón at the start of 2025, equivalent to 12.2% of the Valencian Community (Comunidad Valenciana). That figure includes electrical installers, but also plumbers, HVAC installers, plasterers, painters and waterproofing firms.
For a buyer, what matters is not so much how many electricians there are in the province as what type of customer your company serves. A business that lives on switchboards and maintenance for industrial units is nothing like one focused on homes, refurbishments or street lighting, even though both appear in the same statistical box.

What affects the value of electrical installation businesses in Castellón
The make-up of the portfolio sets the price. Electrical maintenance contracts with industry, residential owners' associations or retail chains bring recurring income and long relationships; work for developers or building contractors brings volume, but also long payment periods and dependence on a few clients. If a single customer accounts for a large share of turnover, the buyer will want to know whether that relationship is in writing and whether it would survive your departure.
Working capital is a classic point of friction. Progress certifications awaiting payment, retentions held as guarantees and materials stockpiled for work in progress change a great deal from one month to the next. Agreeing from the outset how working capital will be measured at the completion date prevents a good negotiation from being spoiled at the end.
In an electrical company, the buyer also examines who is named as technical manager, which installer categories the company holds, whether there is high-voltage work or work on installations that require periodic inspections, and what public liability insurance is in place. Open claims or installations still awaiting legalisation are detected in the review, so it is better that you disclose them yourself.
Illustrative example: two installers with similar profit may receive very different offers if one has half its activity in contracted maintenance with industrial customers and the other depends on a single building contractor. The difference lies not in the trade, but in the risk the buyer takes on.

Frequently asked questions
Not at provincial level with that detail. INE statistics group electrical installation with the rest of specialised construction, which totals 2,597 establishments in the province. At the level of the Valencian Community, the group of electrical, plumbing and other installations brings together 9,321 companies, without separating electrical work.
A customer base with contracted maintenance, a technical team that works without depending on the owner, a good reputation with local industry or property managers, and accounts that clearly separate installation work, service and supply of materials.
Each job is reviewed one by one: quote, progress, outstanding payments and possible overruns. The usual approach is to agree who takes on the result of each open job and how the price is adjusted according to the actual working capital at the completion date.
Yes, it is a possible exit for small installers, because the technician already knows the customers and the trade. The difficulty usually lies in the financing, which may combine a bank loan, the buyer's own funds and a deferred part of the price.
Unlegalised installations, customer claims, pending warranties, dependence on one customer or one person, verbal maintenance contracts and vehicles or tools in poor condition. Detecting them early and explaining them protects the price.
