Why book with us in Walthamstow
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
How much does a loft insulation top-up cost in Walthamstow?
Installing insulation in a home is zero-rated for VAT until 31 March 2027 and 5% after that, under HMRC's rules for energy-saving materials (notice 708/6).

Questions about a loft insulation top-up in Walthamstow
Will I get a written quote for work in Walthamstow?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
Do you charge extra to travel to Walthamstow?
Not normally. Our guide prices include normal travel to Walthamstow. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can a landlord in Walthamstow book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Is it worth topping up 100 mm of loft insulation?
Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
Can new insulation go on top of old insulation?
Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.
