A fixed electrical installation, not an appliance — which is why it requires a qualified installer, notification to the network operator, and an assessment of whether your supply can actually take
It depends almost entirely on how much of the generated electricity you use yourself, because the value of a unit you consume is far higher than the value of a unit you export — and that single ratio
Sound travels as vibration through structure and as airborne pressure waves through gaps, and effective treatment addresses both. Almost everything sold as soundproofing addresses neither, which is
By adjusting the flow through each radiator so they all heat at a similar rate — because water takes the path of least resistance, which means radiators nearest the pump get too much and distant ones
The downward movement of the ground beneath a building's foundations, causing the structure to move with it. It is the most feared word in home ownership, and the fear is disproportionate to how most
Two entirely separate approvals that people routinely conflate. Planning permission governs whether a development is acceptable in principle — its appearance, scale and effect on neighbours and the
An allowance included in a price for work that cannot yet be defined — and understanding it is the key to knowing which parts of a builder's quote are firm and which are not. What it is. Where an
A barrier built into a cavity wall to collect water that has crossed the outer leaf and direct it back outside — and missing or badly installed cavity trays are among the most common causes of
A screed is a levelling layer laid over a structural floor to provide a flat surface for the finish; a damp proof membrane (DPM) is a barrier preventing moisture rising from the ground through the
There is no general rule — not the left-hand side, not the side with the posts — and every widely repeated shortcut is a myth. Ownership is determined by the title documents, and frequently by
An insurance policy that stands behind a contractor's own guarantee, so that the guarantee remains usable if the contractor ceases to trade — which is precisely when a guarantee is otherwise
The Construction (Design and Management) Regulations, governing health and safety in construction — and yes, they apply to domestic projects, which surprises almost every homeowner having work done.
You already have a contract — the question is whether its terms are recorded — and for anything beyond a small job, a written agreement is the difference between a manageable dispute and an
A percentage of each payment withheld by the client until the work is demonstrably complete and any defects appearing within an agreed period have been corrected — an incentive for the contractor to
A detailed written description of exactly what is to be done, item by item — and it is the single most effective protection against disputes on a building project, because most disputes are about
Different professions with different training, different legal protections and different jobs — and engaging the wrong one wastes money and time. Architect. Designs buildings and spaces, prepares
Because they fail through different mechanisms: timber decays, and uPVC's failures are almost entirely in the components rather than the frame material. How timber windows fail: Rot, where moisture
In far more places than most people expect, and the age of the property is the main guide — asbestos was banned in stages, with the final ban on all use in the UK in 1999. Any building constructed or
No — the covering sits between the heat source and the room, so its thermal resistance directly determines how well the system performs, and some coverings simply throttle it. The number that governs
Because a chimney works by draught — hot gas rising creates suction that pulls smoke up — and anything that weakens that suction or starves it of replacement air sends smoke the other way. How the
Yes, but only in specific zones and to specific depths — and the rules exist because a joist's strength is concentrated in exactly the places people instinctively cut. Why position matters more than
Because a heat pump produces water at a much lower temperature than a gas boiler, and a radiator's output depends heavily on how much hotter it is than the room. The temperature difference. A gas
A thermal bridge — sometimes called a cold bridge — is a path through the building fabric that conducts heat out faster than the surrounding structure. The surface on the inside of that path stays
Tanking is applying a continuous waterproof layer to a wall or floor before the tiles go on — and it is what separates a wet room that works from one that quietly destroys the structure around it.
