Use the summer lull to get your gas business in order
By Jordan Valentine-Dunn, Gas Safe registered engineer · 9 July 2026
The quiet summer weeks are the best time to do the jobs that never fit in winter. Chase the invoices you're still owed, tidy your customer and property records, pre-book autumn services while diaries are open, and review your day rate before the busy season. A few hours now buys a calmer October.
Chase the money you're owed
Unpaid invoices are easy to let slide when you're flat out, and summer is when you finally have time to go after them. Money owed to you is an interest-free loan you've given someone else, so pull the list and work through it while you can.
- List every invoice that's past its terms, oldest first.
- Send a short, friendly reminder; most late payment is forgetfulness, not refusal.
- Make it easy to pay: a card link or bank details on the invoice itself gets you paid faster than 'let me know how you'd like to settle up'.
- Set clearer terms for next time, so you're not having this chase again in January.
Tidy your records while it's quiet
Winter is no time to sort out a shoebox of job sheets. The quiet season is. Get your customers, properties, appliances and certificates in order now, so that when the autumn renewals land, the history you need is a search away, not a rummage.
- Reconcile who's actually due to renew over the next six months.
- Merge duplicate customer entries so one person isn't three half-records.
- Check every property has its appliances and its latest certificate on file.
- Back up anything that only lives on paper or on your phone.
Pre-book the autumn before it books you
The autumn rush is completely predictable, which is exactly why you can get ahead of it. A service booked in August isn't competing with a no-heat call-out in November, so use the summer outreach to fill your diary in the order that makes sense, not the order the phone happens to ring.
Pull everything due September to December
Services and landlord renewals both. That list is your warm outreach for the next two months.
Reach out now with a gentle nudge
A boiler serviced before the cold snap is far less likely to leave a customer without heat in December, and they know it.
Batch by area and week
Group nearby jobs into fewer trips. For landlord checks, the two-month early window lets you bring a renewal forward without moving its annual date.
Review your pricing
By mid-year the new tax year has settled and you know what your costs actually are. A small, well-signposted price rise is far easier to make in the quiet season than in the thick of winter, so check your day rate still covers your costs and the margin you're aiming for, and give customers fair notice.
Sharpen how you get work
Marketing is the first thing to fall off the list when you're busy, so summer is the time to actually do it. An hour spent on your reputation now feeds the enquiries that carry you through next spring.
- Ask your happiest recent customers for a review while the job's fresh.
- Update your Google Business Profile: photos, services, opening hours.
- Make a simple referral ask part of finishing a job.
- Tidy your quote template so quotes go out same-day, not next week.
The engineers who don't dread October are the ones who spend the summer working on the business, not just in it. None of the above is urgent, which is exactly why it never gets done in season. Do it now.
