Tile Installers in March 2026: Three Pieces of News That Are Eating Into Your Margins
Labour, adhesives, ceramic tiles and official indices. What has changed and what to do before your next quote.
TL;DR
Labour costs have risen 9.7% and installation materials keep getting more expensive. Any quote closed more than 60 days ago may already be generating a loss. The Official Gazette has published the official price revision indices, which are the only legal tool for recovering margin on contracts already awarded.
Adhesives, grouts and ceramic tiles: the materials that are draining the tile installer's margin
Construction material prices continue to rise at a pace that shows no mercy to old quotes. For the tile installer, the most sensitive products are precisely those used in the highest volumes: tile adhesives, grout mortars and ceramic tiles. When these rise at an accelerated annualised rate, the impact doesn't show up on a single invoice — it seeps in gradually throughout the job, which is why many installers only realise they've made a loss when they reach the final settlement.
A quote closed more than 60 days ago with fixed material prices is, today, a quote with negative margin in many cases. The difference between the price you quoted the client and what you now pay at the supplier is coming out of your pocket. Not the supplier's, not the client's. Yours.
The solution is not to turn down jobs or renegotiate aggressively halfway through. It's to build quotes that reflect this reality from the outset: material prices updated to the week of the proposal, and a clear clause defining what happens if the job starts 90 days after the quote is accepted. Without that, you're signing a risk-absorption contract you never negotiated.
Labour up 9.7%: the cost nobody wants to face but that is destroying margins on longer jobs
The ONS published data showing a 9.7% rise in labour costs in new residential construction. For the self-employed tile installer, this number is anything but abstract. If you value your own time based on what you charged last year, you are effectively working at an involuntary discount of nearly 10%. If you subcontract helpers or other trades, what they charge now is no longer what was in your rate card when you drew up the quote.
The problem is compounded on jobs with a deferred start. You close the contract in January, the job starts in April, and labour costs have risen in the meantime. The client has a signed price. You have a cost that has grown. The difference is a direct loss.
The way to stop this is straightforward, but requires discipline: update your labour cost schedule at the start of each quarter and never use previous job quotes as a reference without adjusting the figures. A tiling quote from last year is not a calculation base — it's a trap. Use it as a structure, not as a price list.
Official Gazette indices: the legal tool most tile installers ignore
The Official Gazette published its March 2026 update of the weighted labour cost indices for Q4 2025, along with construction material indices. For those working exclusively in the private sector, this may seem irrelevant. It isn't.
These indices are the legal benchmark for price revision in public contracts, but they also serve as an objective basis for negotiating revisions in private contracts when disputes arise over cost variations. If a client questions why the job value has increased, these indices are the documented proof that your costs rose in a verifiable and official way. Without knowing them, you have no argument. With them, you have figures signed off by the government.
Furthermore, in the event of a dispute or arbitration, whoever presents the official statistical and government indices is in a very different position from someone who simply claims prices went up. Save the PDF of this publication, note the values relevant to your work, and use them whenever you need to justify a price revision to a client or project manager. It is the only instrument you have to legally recover lost margin on contracts already awarded.
What to do before sending your next quote
Before closing any proposal this week, do three things. First, check the prices of adhesives, grouts and ceramic tiles with your usual supplier — don't rely on memory or your last quote as a reference. Second, recalculate the cost of your own time or your worker's time based on current values, not those from last October. Third, include a price revision clause that protects the job if the start date is delayed by more than 30 or 60 days.
If the process of updating and resending quotes is what holds you back, Prummo was built for exactly that. You can update material prices and recalculate the proposal without rewriting everything from scratch, in under two minutes. Try it at prummo.app and see whether it fits your workflow. What doesn't make sense is continuing to send quotes with prices from two months ago when your costs have already changed.
