Knight Plumbing and Heating: 4 Years in the plumbing business

It has been four years since Knight Plumbing and Heating LTD started up. In this time we have grown to be a recognised plumbing business in the Sussex area with clients from Eastbourne across to Chichester and up to Redhill with all areas in-between. Our growth has increased every year by taking on more clients and larger jobs whilst still managing small call-outs for domestic customers. We have been maintaining a block of 139 flats on the Brighton seafront for just over 3 years with an ongoing contract and also 3 commercial units in Lewes. This can include anything from general plumbing maintenance and repairs to larger projects.

Our work includes anything from tap replacements to larger sites with designing and managing the project. We have now completed 2 large housing projects for a developer in Roedean and Hove with talks of more to start. Also converting an Edwardian mansion into a wedding venue with guest suites and ensuite bathrooms in Havant.

Background in plumbing

My background was in commercial heating working for a number of large companies since leaving school where I joined to become an apprentice. I studied plumbing and heating at Brighton college for four years then sat my gas assessments to become a domestic and commercial GasSafe registered engineer, or CORGI as it was called back then.

Working for different companies and working with varied engineers has helped with my own business venture as I can use the good and bad points that I have learnt to manage my own company. I think I have exceeded my own expectations, as starting up a business can be quite intimidating at the beginning but I was willing to give it my all.

I have enjoyed the satisfaction that comes with running a business and pleased that I eventually took the jump to go on my own. Research shows the first 3 years of business are the toughest as it takes time to become established. Also with the uncertainty of 2020 it has become an achievement to keep growing year on year. With the help of close family and friends it has made it achievable to reach my goal.

We are now working closely to start installing renewable energy systems as this is something I take an interest in. With the introduction of heat pumps and now hydrogen boilers we can help reduce the carbon footprint.

Knights plumbing and heating guide to boiler maintenance and installation

Our guide to boiler maintenance and installation

With the cold weather drawing in, now is the perfect time to have your boiler and heating system checked over to prevent costly repairs or potentially a replacement boiler.

Homeowners can help increase the lifespan of their boiler by checking the pressure on the boiler regularly (once a month) and topping up if necessary. On a pressurised system this should be between 1-1.5bar.

Also venting the radiators and removing air from the system is advised. Not only will this prevent air getting back into the boiler and causing it to overheat and potentially damage components it will also reduce your heating bills as the radiators will work to maximum output when full of water.

We recommend a boiler is serviced by a GasSafe engineer annually to maintain a healthy boiler and validates your manufacturers warranty.

How much does a boiler service cost?

A standard boiler service will cost £78 with checks on combustion analysis, flue integrity, gas working pressure, stability, cleaning any components and condense trap, also a visual inspection on seals and appliance overall safety.

Any replacement parts would be subject to additional costs. We are certified Vaillant Mastertech and Baxi approved engineers with breakdown and service experience on all manufacturers including Worcester, Ideal, Alpha and Potterton to name a few.

Boiler installation

The cost of a new boiler will vary from system to system. Whether you’re having a straight combi swap to a complete system upgrade will depend on the amount of work involved. Usually taking anything from 1-4 days.

The existing heating system water will be treated with a cleaner prior to a new installation by means of a Powerflush or system clean to remove iron oxide (sludge) that has built up over the years.

A magnetic filter will usually be installed on the return of the boiler pipework to protect the appliance from any iron oxide that may build up in the system. On completion a inhibitor will be added. This will prolong the life of the new boiler and keep maintenance costs down.

Many boiler manufacturers are offering 10 year warranties on their appliances providing annual servicing is kept up and water quality is satisfactory. The cost of the new boiler will also vary on the make and model that you and your GasSafe engineer decide to install. We can offer maximum warranties on all boiler manufacturers with prices starting from £1600.

Smart heating controls

Smart heating thermostats are a new trend that allows you to control your system on the go from your phone and other devices by connecting to the internet. They can also help reduce your energy bills and usage as you will have full control even if you’re not at home.

The Smart thermostats can also be linked to Smart Themostatic Radiator valves so you can control the temperature of individual rooms. Smart Thermostats start at around £200 including the installation depending on the make and model.

These are different from Smart Meters which most energy providers are offering to install for free. These are used to help monitor the usage of gas in a property. Another way of reducing your energy bills would be to change providers to ones that offer the best deals.
