You do the gas. We do everything else.
We're a Gas Safe registered heating firm in Deal, working across Kent for over 25 years, and we're taking on subcontract engineers. Our office finds the work, quotes it, books it, orders the parts, answers the customer and collects the money. You turn up, do the job properly and invoice one company. The admin that eats a self-employed engineer's evenings stops being yours.

Email us hello@davidosborneheating.comWhat we take off your plate
Running your own gas business means half your week is not gas work. It is quoting, ringing people back, chasing money and finding out the boiler has not turned up. Work with us and the office does all of that, so your hours go into the jobs that pay.
Finding the work
The website, the Google advertising, the reviews and the reputation that make the phone ring are ours. You never spend a penny or an evening on marketing.
Surveying and quoting
Installs arrive surveyed, priced and accepted by the customer. No quotes at the kitchen table, no waiting a week to hear back, no haggling.
Booking and confirming
The office answers the phone, books the job and confirms it with the customer. It appears in your schedule. If they need to move it, the office sorts it.
Calling customers back
“What time will he be here?”, “can I add the radiator?”, “it’s making a noise again” - those calls go to the office, not to you while you are up a loft.
Chasing the money
The customer pays us. You send one invoice to one company, on terms agreed in writing. No chasing homeowners for payment, ever.
Ordering and tracking parts
Boilers, flues, filters and repair parts go on our trade accounts for next-day delivery, and the office checks they have landed before your job. Nothing fronted on your card, no ringing round merchants.
Warranties and paperwork
We register the manufacturer warranty and the Gas Safe notification. Certificates are signed on the app on site and filed for you. Nothing to bring back, nothing to type up.
The awkward bits
Cancellations, customers who change their mind, the odd complaint - the office handles it. You do the job properly and move on to the next one.
What's left for you
Turn up, do the job properly, sign it off on the app, go home. Then invoice us for what you did. That is the whole list.
What it's actually like
Choose the days you work
Full weeks or set days - you tell us your availability and we plan around it. No minimum, no pressure to take what you don’t want.
A real office behind you
A small team in Deal who know the customers by name and answer the phone. Ring them and a person picks up, for you and for the customer.
Paid on agreed terms, in writing
Rates are agreed at interview and confirmed in writing before your first job. You invoice us for what you complete, and only us.
Work you can be proud of
Fixed-price quotes with the right kit specified, customers who have already said yes, and a firm that backs your work when Gas Safe come to inspect it.

- 1
Apply in two minutes
Name, Gas Safe number, the ACS you hold and how many days you can offer. A CV is optional.
- 2
A conversation, not an interview panel
A call or a coffee in Deal with the owner. We talk rates, patch and the kind of work you want.

Your first jobs
We start you on services and gas safety checks, then breakdowns and installs as you want them.
What you'll need to subcontract with us
- Current Gas Safe registration with CCN1 and CENWAT as a minimum
- At least five years on domestic gas boilers
- Your own van - clean and unbranded - with tools and a calibrated flue gas analyser
- Public liability insurance and your UTR / CIS registration
- A basic DBS check, no more than 12 months old (apply on gov.uk)
- Full UK driving licence and a passport or other photo ID
Questions people ask
Can I work as a sole trader or through my own limited company?
Either. We just need your UTR and CIS status, or your company details, and we invoice and pay accordingly.
I have more than one engineer. Can we work together?
Yes, but each engineer is checked and onboarded individually - Gas Safe card, ACS and insurance for every person who attends a job under our name.
Do I need my own van and tools?
For the field role, yes, including a calibrated flue gas analyser. Consumables for repairs are ordered through our accounts.
What insurance do I need?
Current public liability insurance in your name or your company’s. We ask to see the schedule and note the expiry date.
Do you cover my area?
We work across Kent, with most of the diary in CT and ME postcodes. If you’re based further out, apply anyway and say where you’d prefer to work.
What do you pay?
We have a standard rate card for subcontract work. It sits behind a PIN so it stays between us and the engineers we talk to - ring the office or apply and we will send it with our reply. Rates are confirmed in writing before your first job.
