Before letting anyone work on your boiler, there’s one important check every homeowner should make 👇

Are they Gas Safe registered?

Your boiler is one of the most important appliances in your home, and gas work should always be carried out by a properly qualified professional. Checking Gas Safe registration gives you confidence that the engineer working on your boiler has the right qualifications for the job.

Whether you’re booking a boiler service, repair, or a new installation, don’t be afraid to ask the question:

“Are you Gas Safe registered?” 🔧

In our latest blog, we explain why this simple check should always be the first thing you do before choosing a gas engineer.

A service package with us is a ‘no-brainer’ 💭

Our boiler services cost between £99-£120. However, rather than paying an annual service charge, we offer a monthly servicing package for just £10 per month.

The monthly cost includes the cost of your service as well as unlimited call outs.

It’s a ‘no brainer’ to upgrade to our servicing package and have peace of mind that we’re on hand for calls outs when you need us.

Has your boiler stopped working or is it showing a low-pressure warning? ❌

Your boiler needs the correct pressure to operate efficiently, and a drop in pressure can sometimes be a simple issue to resolve. However, if your boiler keeps losing pressure or the problem returns, it could be a sign that something needs professional attention.

In our latest blog, we explain:

✅ Why boiler pressure drops
✅ How to safely check your boiler pressure
✅ What you can do to reset the pressure
✅ When it’s time to call a professional engineer

Understanding your boiler can help you spot problems early and avoid unexpected breakdowns, especially when you need your heating most.

Our Top Tips for a healthy heating system 🔧

If you want to keep your heating system in top shape without spending a fortune we have three easy tips you can do yourself this summer:

1️⃣ Turn it on once a month: Run your heating for just 10 to 15 minutes once a month during summer. This keeps the internal pump from seizing up through lack of use

2️⃣ Check the pressure: Keep an eye on your boiler’s pressure gauge. It should sit comfortably between 1 and 1.5 bar. If it drops, it might need topping up

3️⃣ Bleed your radiators: If you noticed cold spots at the top of your radiators last winter, bleed them now so they are ready to heat evenly when the cold weather returns
