We needed self levelling concrete quickly so ordered it for next working day delivery. So worth the price as it was delivered by 9 am the next day so the workmen could get straight on to the job. Very efficient service and communication. Product was great and went down so well and quick drying so work could commence next day.

No service Saturday at all so on their website shows you can call them from Monday to Saturday no problem but it’s not true. Also when I paid they didn’t show me my delivery date???? And can’t communicate with them either.

Hi,
Thank you for your feedback. We’re sorry for any confusion caused over the weekend. We understand how frustrating it must have been not being able to contact us on Saturday and not having clear information regarding your delivery date at the time of payment. We’re looking into this to make sure our website information and communication are clear and accurate.
We spoke to you this morning, following the bank holiday weekend, and confirmed that your delivery is scheduled for your chosen delivery date, as requested by yourself. We hope this has now clarified the arrangements and reassured you that your delivery is proceeding as planned.
Thank you for your patience and understanding.
Kind regards,

Had our underfloor heating for a little while now. Works perfectly well and we use it on an automatic timer so when we get up our feet are nice and warm straight away. Also helps save energy having them come on and off when needed and the thermostat works well to turn off the heating when at temperature. Highly recommend for electric underfloor heating. Also a fair price compared to what we have seen else where.
Delivery was easy and on time. Arrived with everything we needed and the YouTube explanation of insulation helped us a lot so we could install it ourselves.
