Porcelain tile quality

How to determine the quality of a porcelain tile.

How can I judge the quality of a porcelain tile?


There are several factors to consider when judging the quality of a porcelain tile:


Density: Porcelain tiles are made from a denser clay than other types of tile, which makes them more durable and resistant to moisture.


Water Absorption: Porcelain tiles have a water absorption rate of less than 0.5%, which makes them suitable for indoor and outdoor use.


PEI rating: PEI rating is a measure of a tile's resistance to wear and tear. Tiles with a higher PEI rating are more suitable for high traffic areas.


Surface finish: Porcelain tiles come in a variety of finishes, including polished, honed, and textured. The finish of a tile can affect its slip resistance and durability.


Quality Control: Quality control is important for ensuring that tiles are consistent in size and color, and that they meet industry standards for strength and durability.


Brand reputation: Look for a reputable brand with a history of producing high-quality tiles, and check customer reviews to see what other people have experienced with the product.


Warranty: Look for a tile that comes with a warranty that protects against defects in workmanship and materials.



It can be difficult to judge the quality of a porcelain tile just by looking at it. Some factors, such as surface finish and colour, can be visually assessed, but others, such as density and water absorption rate, are not visible. However, there are some things you can look for to get an idea of the tile's quality:


Look for uniformity in size and colour: Tiles that are consistent in size and colour are generally of higher quality.


Check for defects: Look for chips, cracks, or other defects in the tile.


Check the surface finish: A smooth, glossy finish is generally indicative of a high-quality tile.


Check the edges: Check the edges of the tile to make sure they are clean and straight, with no rough or jagged edges.


Brand reputation: Look for a reputable brand with a history of producing high-quality tiles, and check customer reviews to see what other people have experienced with the product.


It's important to remember that even if a tile looks good on the surface, it may not be of high quality. It is always recommended to check the technical specifications and certifications of the tile before purchasing.



Technical specifications and certifications are important indicators of a tile's quality and performance. Some of the most important technical specifications and certifications to look for when purchasing tiles include:


Water Absorption: The water absorption rate of a tile is a measure of how much water it can absorb before it begins to deteriorate. Tiles with a water absorption rate of less than 0.5% are considered porcelain tiles and are suitable for indoor and outdoor use.


PEI rating: The PEI rating is a measure of a tile's resistance to wear and tear. Tiles with a higher PEI rating are more suitable for high traffic areas.


Breaking strength: Breaking strength is a measure of a tile's strength and durability. Tiles with a higher breaking strength are more resistant to damage.


Slip resistance: Slip resistance is a measure of a tile's ability to prevent slips and falls. Tiles with a high slip resistance rating are more suitable for wet or high traffic areas.


Certifications: Tiles that have been certified by organizations such as the Porcelain Enamel Institute (PEI) and the Ceramic Tile Institute of America (CTIOA) have been tested and found to meet industry standards for quality and performance.


ASTM Standards: Tiles that meet ASTM Standards are considered to be of good quality and are suitable for use in residential and commercial settings.


ISO Standards: Tiles that meet ISO Standards are considered to be of good quality and are suitable for use in residential and commercial settings.


It is important to note that not all tile manufacturers or brands have the same certification and it can vary according to the region. It is always recommended to check the certifications and standards of the tile before purchasing.

Case Study – Building Without Insurance

by Niket Kapur • 20 March 2026
A homeowner commenced building works on their property without arranging appropriate site insurance. This is not uncommon. There is often an assumption that either the contractor’s insurance will be sufficient, or that an existing household policy will continue to provide cover. In this case, neither applied. Partway through the project, it became clear that there was no valid insurance in place. At that stage, the position became significantly more difficult. Insurers were unwilling to provide cover retrospectively. From their perspective, the risk had already begun without protection, and they were being asked to step into an unknown position. The property was effectively uninsured during an active construction project. We were instructed to review the situation. A structured approach was taken, including: Clearly defining the scope and stage of the works Presenting the risk in a transparent and credible way Engaging directly with specialist insurers Following extensive discussions, we were able to: Secure appropriate site insurance cover Bring the project back within an insurable and protected framework This was not straightforward. It required persistence and a clear understanding of how insurers assess risk. On a construction project, the absence of insurance is not a minor oversight. It is a significant exposure. If you are planning a build, it is worth ensuring that the right cover is in place before work begins. 

Case Study – Council Tax, Planning Delays and Structural Issues

by Niket Kapur • 20 March 2026
A homeowner commenced a significant renovation project with the intention of improving and extending their property. The project did not proceed as expected. There were delays with planning, and during the course of the works, structural issues emerged which required a reassessment of the build. Ultimately, a substantial part of the property had to be demolished mid-project. At this stage, the property was clearly uninhabitable. However, the local authority took a different view. They imposed double council tax on the basis that the property was empty, applying the standard premium used to discourage long-term vacant properties. Representations were made to explain the position. These were rejected. The authority maintained a rigid stance and would not accept that the condition of the property and the nature of the works justified relief. The charges continued to accrue. We were instructed to review the situation. A detailed and structured approach was taken, including assembling the appropriate evidence, reframing the basis of the claim, and engaging with the local authority in a more targeted way. The outcome was clear: Full council tax waiver achieved Over £10,000 recovered for the client Ongoing liability removed This is not an uncommon scenario. Local authorities will often apply standard rules without properly considering the specific circumstances of a construction project. Initial refusals are frequent, but they are not always correct. A properly prepared and presented case can materially change the outcome. Situations like this arise regularly on construction projects. Addressing them correctly can make a significant financial difference. Sunil K Radia The Building Guidance Partnership Telephone (020) 8076 3110 WhatsApp +44 7507 705376 www.theBGP.co.uk

Regulatory Compliance Oversights That Could Sink Your Construction Project

by Niket Kapur • 20 March 2026
Most homeowners focus on design, finishes and cost when undertaking a building project. Very few focus on compliance. That is where serious problems arise. This note sets out the key regulatory and risk areas that are frequently overlooked. These are not minor technicalities. They are issues that can expose you to financial loss, uninsured risk and legal liability. 1. Notifying Your Mortgage Lender If your property is subject to a mortgage, your lender has a legal charge over it. That property is their security. Most mortgage terms require you to notify the lender before carrying out structural works Some lenders require formal consent Failure to notify can place you in breach of your mortgage conditions This is often ignored. It should not be. 2. Insurance During Construction Standard household insurance is usually not valid during major renovation or structural works. Many policies specifically exclude properties under construction Continuing without appropriate cover can leave you completely exposed You should: Notify your existing insurer before works commence Arrange specialist renovation insurance where required Ensure cover includes fire, flood, theft, vandalism and public liability Do not assume you are covered. Check. 3. Contractor Insurance Is Not a Substitute Many homeowners assume the contractor’s insurance will protect them. That assumption is dangerous. You must verify: The level of cover is sufficient for the scale of the project The policy includes public liability, employer’s liability and contract works Cover extends to damage to neighbouring properties Liability includes injury to third parties, including trespassers Do not accept a certificate at face value. Review the detail. 4. VAT: Getting It Wrong Is Expensive VAT treatment in construction is complex but critical. New builds may qualify for 0 percent VAT Properties empty for two years or more may qualify for 5 percent VAT on renovation works Evidence of vacancy is essential and must be properly assembled Failure to structure this correctly can cost many thousands of pounds. 5. Council Tax on Uninhabitable Properties Where a property is genuinely uninhabitable, relief or exemption from council tax may be available. In practice: Applications are often rejected at first instance Local authorities do not always guide applicants through the correct route A structured and informed approach is required to secure the correct outcome We regularly assist clients in securing substantial savings, including backdated recoveries where appropriate. 6. Site Safety and Residual Liability Even when a contractor is in possession of the site, the homeowner can still carry risk. If someone is injured on site, including a passer-by or trespasser, liability may arise Simply appointing a contractor does not remove your exposure You should ensure: Proper site security is in place Risk assessments and method statements are being followed Insurance arrangements align with the actual risks on site This is not theoretical. Claims do arise in these circumstances. Final Thought These issues are rarely considered at the outset, yet they carry real consequences. Getting them right early avoids problems later.
