One number in your phone, not three.
Keystone Home Repairs was built around a simple frustration: homeowners should not need three different tradespeople saved in their phone just to keep a house running.

Take out the keystone and everything else shifts.
A keystone is the single stone that holds an arch together. Remove it and the structure it was carrying comes apart. That is the role we want to play in a home: the one call that holds the rest together, whether it is a heating breakdown, a leaking pipe or a full bathroom refit.
Most households end up with a heating engineer, a plumber and an electrician saved separately, and no one of them takes responsibility for the bit in the middle. Underfloor heating is plumbing and electrical at once. A bathroom is three trades in a room two people can barely work in. A roof leak becomes a ceiling problem and sometimes a wiring problem.
Splitting those jobs across three firms does not just cost more in call-outs. It costs time waiting for the next trade to be free, and it means nobody has the whole picture of how your systems fit together.
So Keystone holds the certifications that matter across all of it — OFTEC for oil, Gas Safe for gas and LPG, G3 for unvented hot water — and covers the electrical and roofing work alongside. One team, one number, one point of responsibility.
Four things we hold ourselves to
Diagnose, do not guess
Swapping parts until a symptom disappears is expensive and it does not tell you what was actually wrong. We test first, then explain what we found in terms that make sense.
Price before we start
You get the cost of the work up front. If a repair turns out to be uneconomic, we will say so and price the replacement rather than quietly patching it.
Say when it is not worth it
A powerflush your system does not need, a cylinder that has years left in it — turning down work that is not warranted is part of being worth calling back.
Leave the paperwork in order
Whatever your fuel type requires, it gets done and it gets handed over. Certification is not an afterthought bolted on when someone asks for it.
The badges that decide who is legally allowed near your boiler.
The recognised registration scheme for oil heating work in the UK. It covers installing, commissioning and servicing oil-fired appliances, along with the tanks and supply pipework that feed them.
A legal requirement for anyone working on gas or LPG appliances in the UK — not a trade preference. It applies to LPG bulk tanks and cylinders just as it does to mains gas.
The competence requirement for unvented hot water storage. Those cylinders hold water at mains pressure, so their safety devices have to be specified, installed and tested by someone qualified to do it.
Our electrical certification is being confirmed. Rather than imply a registration we have not published, the electrical pages say so plainly — and this page will be updated with the scheme and number as soon as it is in place.
Areas we cover
Berkshire, Hampshire, Oxfordshire and Surrey, plus the London Borough of Richmond upon Thames and Bournemouth. Not sure if you are in range? Call and ask — it is usually a yes.
About the business
The point of how we are set up is that heating, plumbing and electrical work is covered by the same outfit rather than three separate firms coordinating around each other. That is what removes the waiting between stages on jobs like a bathroom refit, where the trades constrain one another constantly.
OFTEC registration for oil heating, Gas Safe registration for gas and LPG, and G3 for unvented hot water systems. Our electrical certification is being confirmed and this page will be updated with the scheme and registration number once it is — we would rather state that plainly than imply something we have not yet published.
A keystone is the single stone at the top of an arch that holds the whole structure together. Take it out and everything else shifts. That is the role we want the business to play for a household — the one number that holds the rest together.
Berkshire, Hampshire, Oxfordshire and Surrey, plus the London Borough of Richmond upon Thames and Bournemouth. If you are just outside that, it is still worth asking — the boundary is not a hard line.
