Running local service marketing customer interviews without guesswork

What to take away

A customer interview programme is research, not a sales call, so write your questions and recruitment list first.
In England most local service markets are crowded with very small employers. The ONS bulletin on UK business activity, size and location sets out that size distribution, which shapes who is worth interviewing.
Six to ten interviews per customer type is usually enough for themes to repeat, so stop recruiting rather than chase volume.
Keep answers in the customer's own words and count how often each theme appears. A theme mentioned once is a hunch, not a finding.

Set the criteria before you recruit

Write down who counts as a customer. A homeowner buying a boiler service and a facilities manager buying a maintenance contract are different audiences, even if both pay you.

Define interview criteria first

Write down who counts as a customer
Separate homeowner and facilities manager audiences
Decide the geography to interview inside
Use the England target audience breakdown
Define segments before opening a calendar

Decide the geography too. Interview inside the footprint you actually serve, because travel and response times change what people will pay.

Use the local service marketing target audience in England breakdown to define your segments before you open a calendar.

Recruit from your own list first

Existing customers are the cheapest and most honest source. Pull recent buyers, lapsed buyers and people who asked for a quote but never booked. The last group explains the gap between interest and purchase.

Recruit from your own list

Pull recent buyers from your list
Include lapsed buyers
Include quote requests that never booked
Aim for a mix of business sizes
Offer a small incentive if helpful
Say it is research, not a pitch

Aim for a mix of sizes. The GOV.UK collection of long-term trends in UK business demographics is a reminder that most firms are small, so a sample skewed towards large employers will not reflect your market.

Offer a small incentive if it helps, and say the conversation is research, not a pitch.

Ask about the last decision, not opinions

Opinions about advertising are cheap. Recollections of a real purchase are not. Walk the customer through the last time they needed your type of service, from noticing the problem to paying.

Good prompts include where they looked first, who else they contacted and what made them hesitate. Avoid asking whether they would use a service in future, because stated intent rarely matches behaviour.

If you want a structured question set, the audience research guide for England covers how to build one that survives contact with real customers.

Capture the answers in a form you can count

Use one notes template for every interview: a short verbatim quote, a theme label and a channel name. After each session, tally the themes across all interviews.

A spreadsheet beats a long report here. Columns for customer type, trigger, channels considered, objections and price sensitivity let you spot patterns quickly.

Do not tidy the language. If a customer says the quote was "more than I expected for a Tuesday", keep that phrase. It says more than a summary line about price perception.

Worked example: a two-person plumbing firm in England

Suppose a two-person plumbing business in a Midlands town runs eight interviews. Four come from existing customers and four from people who requested a quote but did not book.

Six of the eight mention searching on a phone and calling the first firm whose site loaded quickly. Three say they abandoned a form because they could not see a price range.

The firm tests a mobile page with a clear call button and an indicative range for a standard callout. It spends £300 a month on local search ads, up from £200, and books four extra jobs a month at £180 each. That is £720 of extra revenue against £300 of extra spend, all illustrative figures.

Turn notes into a decision

Bring the tally to whoever controls the budget: the themes, the channels customers used and the objections that came up most often.

Then agree one change to test, one measure to watch and a date to review it. The IAB UK SME toolkit for digital advertising planning can help frame the channel and budget discussion.

If nothing changes afterwards, the exercise was a diary entry, not research.

Common questions

How many customer interviews should a small local business run?

Six to ten per customer type is a practical starting range. Stop when themes repeat and no new objections appear.

Should I pay people to take part?

A small voucher or a free callout is usually enough for a 20 to 30 minute conversation. Make clear that no sale will be attempted.

Can I run interviews by phone or video?

Yes. Phone and video are often easier for tradespeople and busy households. Meeting in person helps only if you need to see a site or a document.
