Not measurably lower?

We remove the system for a full refund.

And 10 years parts and labour, included. Every system also comes with a 10-year parts and labour warranty (the compressor is covered for 1 year). Want everything covered? Optional Gold Pack membership is £199 per year. It covers everything, including replacement of the compressor, and includes a yearly onsite system check and remote humidity monitoring. Ask us about Gold Pack.

A Fixed Price for Your Home

Basic installation is £1,200, and a power point in the loft is £250 if you need one. Access to power, drainage and the vent location vary from one property to the next, so we confirm your exact fixed price at a survey before any work starts.

📋

1. Check the price, then book a survey

Once the prices suit you, book a survey. A Dryzen specialist visits, checks moisture levels and your loft, and talks through what you need. No obligation to proceed.

What Shapes Your Quote

The survey looks at the things that genuinely change the job, so the number you are given is the number you pay.

✓ The size and layout of the home, and how many units it needs (one unit covers about 150 m²)
✓ Loft access and where the unit and ducting can go
✓ Access to power (and whether the loft needs a £250 power point) and drainage
✓ Where the vents sit

Cheaper to live with

Running costs are around £20 a year, the filters are included for 10 years, and many customers find a drier home is easier and cheaper to heat, particularly in older properties. The system is designed to last 20 years or more with regular filter changes.
