We initially hired Northwest Plumbing and Heating because they were the cheapest quote. They came out to replace our office heating boiler. They quoted the price over the phone before starting work. It was exactly what they said it would be without any surprises.They arrived on time, explained what they needed to do, were very thorough, working through an identified schedule. They worked quickly without any mess or noise.They were very busy when I booked, so we had to wait a few days. I was willing to wait because of the very good reviews they had.I would use them again and would recommend them to anyone needing a reliable plumber.

Frequently Asked Questions
Air Conditioning Questions
Are you Gas Safe for domestic and commercial work?
Yes. We are Gas Safe registered for both domestic and commercial work.
Do you cover emergency callouts?
Yes. If your boiler breaks down or you have no heating or hot water, get in touch and we'll do our best to get to you as quickly as possible.
Why does my boiler keep losing pressure?
Low pressure is one of the most common boiler issues we get called out for. It is often caused by a small leak somewhere in the system, a faulty pressure relief valve, or radiators that need bleeding. Give us a call and we can diagnose it quickly.
How long does a boiler installation take?
A straightforward like-for-like boiler swap usually takes around one day. A more complex installation, such as a system change or moving the boiler, may take a little longer. We always give you a clear timeframe before we start.
Do you service all makes and models of boiler?
Yes, we service all major makes and models. Annual servicing keeps your boiler running efficiently, maintains your warranty, and helps catch small problems before they become expensive ones.
What areas in Lancashire do you cover?

How is Legionella assessment pricing worked out?
Legionella risk assessments start from £300 plus VAT and are priced per assessment.
Who legally needs a Legionella risk assessment?
Under the Health and Safety at Work Act, any employer or person in control of premises, including landlords, has a legal duty to assess the risk of Legionella in their water systems. This includes offices, rental properties, care homes, and other commercial or residential premises.
How often does a Legionella risk assessment need to be done?
There is no fixed legal frequency, but the HSE recommends reviewing your assessment whenever there is reason to believe it may no longer be valid, typically every two years, or sooner if there are significant changes to the property or water system.
How long does a Legionella risk assessment take?
For most residential and smaller commercial properties, the on-site inspection typically takes between one and two hours. We then provide you with a full written report and any recommendations.
Do I receive a certificate after the assessment?
Yes. Once the assessment is complete, we provide a full written risk assessment report documenting our findings, any identified risks, and recommended control measures. You can keep this on file to demonstrate compliance.
What do I get after a Legionella assessment?
You receive a site risk assessment with practical notes and clear recommendations for the property.
Do you install and service air conditioning?
Yes. We now have a dedicated air conditioning engineer, so we cover installation, servicing, and repair for both domestic and commercial properties across Lancashire.
Do you work on both homes and commercial properties?
Yes. We handle air conditioning for homes, offices, shops, and other commercial sites. Just let us know a bit about the property and we will advise on the best option.
How often should air conditioning be serviced?
We generally recommend an annual service to keep a system running efficiently, maintain performance, and catch small issues early. We can set up a routine that suits your property.
Can you repair an existing air conditioning unit?
Yes. If your air conditioning is not working as it should, get in touch. We will diagnose the fault and give you a clear quote before carrying out any repair.
