The Numbers Behind the Business: A Trades Contact Register for Small UK Firms

The gap in the business record

A small UK firm usually has a respectable file for the formal relationships. The accountant’s engagement letter is somewhere. The bank mandate is signed. The insurance schedule may even be in the right folder. The informal relationships are different. They live in a mobile phone, in a message thread, or in the memory of the person who normally makes the call.

That works until it does not. A pipe leaks on a Friday afternoon, a shredding collection is missed, or a courier needs directions to a side entrance. The person who knows the number is on leave, in a meeting, or simply unavailable. The firm then spends twenty minutes searching for a tradesperson it has used for years.

The answer is not a new software platform. It is a single contact register — a ring list — that records the trades the business depends on, what they charge, and what they need before they arrive. It is deliberately unglamorous. Its value lies in being complete, current and findable by someone who is not the usual point of contact.

What belongs on the register

A useful register is more than a list of names and numbers. Each entry should answer the questions a stand-in would ask before making the call.

For each trade, record the business name, the person who normally answers, a mobile number and a landline if one exists. Add the email address used for quotes and invoices. Then add the practical details: the agreed rate or call-out charge, the usual response time, and any minimum spend. If the firm has a purchase order or account number, record it here rather than hunting for it later.

The most overlooked column is the one headed “what they need from us”. An electrician may need the fuse board location and a clear parking space. A shredding collector may need the bins to be accessible before 7am. A courier may need the goods-ready time and a contact name at the door. Recording these details turns a phone call into a short, useful conversation rather than a series of questions.

It is also worth noting the boundaries. Does the tradesperson work weekends? Do they invoice monthly or on completion? Are they insured for work at height? These are not contractual terms in every case, but they are the details that prevent an awkward surprise.

Where the register should live

A register that exists only on one person’s phone is not a register. It is a personal contact list with a business label. The file should sit where the work happens: in the shared drive or intranet the firm already uses, with a printed copy in the office folder that covers absences. If the business uses a shared inbox, a pinned message with the link is useful. If it uses a simple document system, a single page is enough.

The format matters less than the access. A spreadsheet is perfectly adequate. A table in a word-processing document is also fine. The point is that a colleague, a temporary administrator or a virtual assistant can open it without asking for a password that only one person knows.

A printed copy has one further advantage: it works when the internet does not. Keep it in the same place as the business continuity folder, and mark it with a review date. A register that is two years old is better than no register, but not by much.

Building it in one afternoon

The register can be assembled in a single working session. Start with the trades that have been used in the last twelve months. Bank statements and invoice files are the best source. Look for repeat payments to electricians, plumbers, locksmiths, cleaners, shredding companies, couriers and IT support. Add the regular service providers: boiler servicing, fire extinguisher checks, PAT testing and waste collection.

For each entry, check the number against the last invoice or email. Do not rely on the number saved in a phone if the invoice shows a different one. Record the agreed rate from the most recent quote or invoice. If no rate is written down, mark it as “to confirm” rather than guessing.

Then add the practical notes. This is the part that takes the longest, because it requires thinking about how each trade actually works with the firm. A plumber may need to know where the stopcock is. A locksmith may need proof of address before attending. A shredding collector may need a signed waste transfer note. These details belong on the register, not in someone’s head.

Finish by adding a review date. A quarterly check is usually enough for small firms. The review need not be elaborate: confirm the numbers still work, update any rates that have changed, and remove trades that are no longer used.

Testing it with someone else

The real test of a contact register is whether another person can use it. Once the register is built, ask a colleague who does not normally handle supplier calls to use it for a simple task. They might request a quote for a small repair or confirm a collection time. Watch where they hesitate. If they cannot find the account number, the rate or the access note, the register needs another column or a clearer heading.

This test is more useful than a tidy layout. A register that looks impressive but requires the original author to interpret it has not solved the resilience problem. A plain table that a stand-in can follow is the better outcome.

A small piece of operational insurance

The trades a firm relies on are part of its operating model, even when they are not on the organisation chart. Recording their details is not bureaucracy. It is a modest form of insurance against absence, turnover and the ordinary disruption of a working week. Built in an afternoon and tested by someone else, the register gives a small UK firm something valuable: the confidence that the number can be found, the rate is known, and the person arriving knows what to expect.
