A legal retainer, and how to make it pay

A retainer is the easiest legal arrangement to buy and the easiest to waste. Most of the value sits in two things nobody discusses at the point of signing - what the scope actually says, and whether anyone in the business gets into the habit of using it. This is the whole arc, from working out whether you need one through to knowing when to change it. If you only want to know what a retainer is, start with how a legal retainer works instead.

Key takeaways
  1. A retainer covers routine, ongoing legal work at a fixed monthly fee. Project work - a company sale, a share scheme, litigation - is priced separately, and any retainer implying otherwise is worth reading twice.
  2. The comparison worth making is not retainer against law firm. It is retainer against an in-house hire, and the gap in cost is roughly an order of magnitude.
  3. Scope is the whole document. What is in, what is out, how fast you get an answer, and what happens when something falls outside - agreed at the start, not discovered mid-problem.
  4. Retainers fail through underuse far more often than through overuse. The businesses getting value are the ones where asking became a habit rather than an escalation.
  5. Review it annually and when the business changes shape. A retainer scoped for a ten-person company is the wrong size at forty.
01
Work out what you need

Count the questions, not the contracts

Most businesses reach for a retainer at the point legal work stops being an event and starts being a rhythm. The useful test is not how many contracts you sign. It is how often somebody in the business has a question and does nothing about it.

Three signals, and any two of them usually mean a retainer is the right shape.

  1. Frequency. Something legal comes up most weeks - a customer contract, a supplier's terms, an employment question, a query about what you can say in marketing.
  2. Deferral. Questions get parked because nobody wants to trigger an hourly bill for something which might take five minutes to answer. This is the expensive one, because the cost is invisible until it is not.
  3. Speed. You need answers in days rather than weeks, and the deal moves faster than a procurement process for legal advice.

If legal work arrives twice a year in large lumps, a retainer is the wrong instrument and paying per matter is cheaper. That is a real answer, not a disclaimer.

02
Compare the routes

Four ways to buy it, and they are not close

There are four routes to ongoing legal support, and the difference between them is mostly about who carries the cost of your quiet months.

  1. Hire in-house. A permanent lawyer, fully loaded with salary, employer NICs, pension, holiday, software and recruitment. For a commercial solicitor with real experience this is a six-figure commitment before anyone has reviewed a contract. It buys availability and context nothing else matches, and it is the right answer above a certain size.
  2. Retain. A fixed monthly fee for the routine work, agreed in advance. You carry no employment risk and no recruitment cycle, and the cost is predictable enough to budget.
  3. Pay per matter. Instruct a firm when something happens. Cheapest in a quiet year, and the arrangement most likely to leave small questions unasked.
  4. Buy a bundle. HR and employment providers sell fixed monthly packages with helplines and tribunal cover. Genuinely good at what they do, and a different product from a commercial solicitor - see what an employment law retainer actually covers.

The honest comparison is the second against the first, because that is the decision most businesses are actually making. Do you need an in-house lawyer? works through it properly, and fractional general counsel covers the senior end of the same question.

03
Scope it properly

The scope is the entire document

Everything which goes wrong with a retainer goes wrong here, and it goes wrong in one direction: the scope was vague, both sides assumed generously in their own favour, and the disagreement arrived at the worst possible moment.

Four things a retainer agreement has to say plainly.

  1. What is in. Not "legal advice" but the actual work - contract review, standard document drafting, commercial and employment questions, a periodic review of where you stand.
  2. What is out. The harder half, and the one usually left blank. Project work sits outside a routine retainer: a company sale, due diligence, a share scheme, litigation, a bespoke set of terms drafted from scratch.
  3. How fast. A response time you can plan around, and an escalation route for the thing which cannot wait.
  4. What happens at the edge. When something falls outside, are you told before the work starts, or invoiced after? There is only one acceptable answer and it is worth seeing in writing.

Silva's own retainer states the scope at the outset and flags anything outside it before proceeding rather than after. That is not a generous gesture; it is the only version of this which works, because the alternative is a surprise invoice and a lost client.

A representative month - where does each land?
A customer sends their own terms and wants them signed this week
HR asks whether a long-standing contractor is really self-employed
A supplier is 60 days late paying and you want to know your options
Marketing wants to know if a comparison claim is safe to publish
You need an NDA and a contractor agreement drafting from the standard set
You have agreed to buy a competitor and need the diligence run
You want to put a share option scheme in for four key staff
A former distributor has issued a claim against you
04
Use it well

Retainers fail through underuse

This is the part nobody writes about, and it is where the money actually is. Businesses which get poor value from a retainer are almost never the ones asking too much. They are the ones who signed it, felt reassured, and carried on exactly as before.

Four habits separate the two.

  1. Let more than one person ask. If every query has to route through the founder, most queries die. Name two or three people who can go direct.
  2. Ask early and badly. A two-line question before the call is worth more than a tidy summary after the deal is agreed. Advice is cheap while the position is still moveable.
  3. Send the whole thing. The email chain, the earlier version, the thing you are worried about. Partial facts produce partial answers, which is the most common cause of advice being wrong.
  4. Say when a deadline is real. Everything is urgent and almost nothing is. Being specific about what actually moves gets the right thing prioritised.

The test after six months is not whether you have used your allocation. It is whether anyone in the business now asks before doing something, instead of after.

05
Review it

The right size changes

A retainer scoped for a ten-person business is the wrong shape at forty, and nobody notices until the relationship is either straining or coasting.

Review annually as a matter of course, and immediately on any of these: a funding round, a first overseas customer, a first consumer customer, a step change in contract size, an acquisition, or a claim which the arrangement handled badly.

Three outcomes are all legitimate. Increase it, because the volume has genuinely grown and you are rationing. Reduce it, because the business has stabilised and the work is now lumpy rather than constant. Or end it, because you have grown into an in-house hire - which is a success, not a failure, and any adviser treating it as the latter is telling you something about themselves.

What matters is that the review happens on a date rather than in a moment of frustration.

What it costs, honestly

One fee for the routine, separate fees for projects

Silva's retainer starts at £775 + VAT a month, fixed and agreed upfront, and it does not change unless your requirements change. That covers the routine layer - contract review, standard drafting, commercial and employment questions, a quarterly review of where you stand, and a direct line to one person who knows the business.

It does not cover project work, and it is not meant to. A company sale, a data room review, a share scheme, a set of terms drafted from scratch, a dispute - each is scoped and priced on its own, and the figures are published on the pricing page rather than left to a conversation. Retaining Silva does not put those inside the monthly fee, and any provider suggesting it would is either charging for them already or planning to disappoint you.

The comparison worth holding in your head is not against an hourly rate. It is against the fully loaded cost of a permanent hire - salary, NICs, pension, holiday, software, recruitment - which for an experienced commercial solicitor runs to six figures before the first contract is looked at.

Silva is a legal consultancy rather than a law firm, and that shapes what we take on. What we cannot help with is published for the same reason the scope is: knowing the edges before you sign is worth more than a warm sentence about partnership.

Frequently asked questions

How much does a legal retainer cost?

Silva's retainer starts at £775 + VAT a month, fixed and agreed before it begins. Across the market, monthly retainers for a growing business typically run from several hundred pounds to a few thousand, depending on scope and response times rather than on headcount. The figure to compare it against is not an hourly rate but the fully loaded cost of an in-house hire, which for an experienced commercial solicitor is a six-figure commitment.

What is included in a legal retainer?

Routine, ongoing legal work. In Silva's case: contract review, drafting of standard documents, commercial and employment questions as they arise, a quarterly review of your legal position, and priority access to one consistent adviser. The precise scope is agreed at the start of the engagement rather than being a fixed list, because the right shape differs by business.

What is not covered by a legal retainer?

Project work. A company sale or purchase, due diligence, a share option scheme, litigation, or a bespoke set of terms drafted from scratch all sit outside a routine retainer and are scoped and priced separately. A retainer claiming to include all of it is either priced for the worst case or will disappoint at the point you need it.

Is a legal retainer cheaper than paying hourly?

It depends entirely on how often legal questions arise. In a year with two discrete matters, paying per matter is cheaper. Where something comes up most weeks, a retainer is usually cheaper and always more predictable. The hidden cost of hourly billing is the question nobody asks because they do not want to start the clock, and that cost only becomes visible when something has already gone wrong.

Do I need an in-house lawyer or a legal retainer?

The deciding factors are volume and the need for someone in the room. An in-house lawyer buys availability and business context nothing else matches, at a six-figure fully loaded cost, and makes sense above a certain size or complexity. A retainer gives most of the coverage without the employment commitment or the recruitment cycle. Many businesses run a retainer for years and then grow into a hire, which is the normal progression rather than a change of mind.

Can you cancel a legal retainer?

Yes, subject to whatever notice period the agreement sets - typically one to three months. Check two things before signing: the notice period itself, and whether any minimum term applies. A retainer worth having does not need to lock you in, and a long minimum term is usually a sign the pricing depends on you underusing it.

Find out what yours should cover

The useful first conversation is not about price, it is about scope - what your business actually generates, what falls outside, and whether a retainer is the right instrument at all. Silva will say if it is not.
