The service
A proper service, not a quick glance.
A boiler service is your once-a-year health check. We inspect and test the appliance to manufacturer standards, check it's burning safely and efficiently, and spot small issues before they turn into expensive breakdowns, usually on the coldest day of the year.
On every standard service we test the operation of all safety devices, flues, gas pressures, seals and emissions, and clean the condensate trap, system filters and scale devices. Where the manufacturer's instructions call for it, we carry out a full service to their specification. You get a certificate for every service we do, sent over electronically.
A service also keeps your manufacturer warranty valid. Most need an annual service by a registered engineer. We're Gas Safe registered (no. 205434), manufacturer-approved by Vaillant and Glowworm, and we service all makes and models.
- Manufacturer standard: tested and inspected the way it should be
- Protects your warranty: keeps Vaillant & Glowworm guarantees valid
- Catches faults early: cheaper than an emergency breakdown
- All makes serviced: whatever boiler you have

Running poorly? A service often tells you why
If your boiler is noisy, slow to heat, or your bills have crept up, a service is the first thing to book. We'll tell you whether it's a simple fix, whether a powerflush would help, or whether a new boiler would pay for itself.
Either way you get an honest answer and upfront pricing for any work, and never any pressure to spend. Every job we do is guaranteed.
