Boiler Keeps Playing Up

Pressure loss, lockouts, strange noises or error codes usually have a fixable cause. Book a boiler repair visit.

Service Due Before Winter

An annual boiler service keeps your warranty valid and catches faults before the cold weather.

Winter Heating Checklist

Get Your Heating Ready for Winter

Most heating breakdowns in St Albans happen in the first cold weeks, when a system that has sat idle all summer is suddenly asked to run for hours a day. A few simple checks now can save you a cold night later:

  • Book your boiler service before the October rush
  • Run the heating for 15 minutes and check every radiator warms fully
  • Check the pressure gauge reads between 1 and 1.5 bar when cold (see why boilers lose pressure)
  • Bleed any radiators that stay cold at the top
  • Test your thermostat and timer, or ask about new heating controls

Sharif bhai did a very good job in my property. He fitted the shower properly and fixed the leak issue. He checked everything carefully and made sure there was no more leaking after the work finished. He was polite, professional, and helpful. The work was neat and clean, and the shower is now working very well. I am happy with his service and I would recommend Sharif bhai to others for plumbing work.

I recently had my boiler serviced by Heatgap( 99 Byron Road,Luton) and I couldn’t be happier with the experience. The Technician arrived on time, was professional, and explained everything clearly. The service was thorough, and they made sure the boiler was running safely and efficiently before leaving. What really stood out was their friendly attitude and attention to detail. They took the time to answer my questions and gave helpful advice on maintaining the boiler. Overall, excellent service from start to finish. I would definitely recommend Heatgap to anyone looking for reliable and professional boiler servicing.

Once every 12 months. Most manufacturers require it to keep the warranty valid. Our guide explains how often you should service your boiler and what a service covers.

If the boiler is fairly new and the fault is a single part, a repair usually makes sense. If it breaks down regularly, is over 10 to 15 years old or your bills keep rising, replacement is often better value. We will give you an honest view either way.

Heat pumps work best in well insulated homes with room for an outdoor unit and a hot water cylinder. We will check your property and tell you honestly whether a heat pump, an electric boiler or a gas boiler suits you best.
