A note from Sam

Small trade.
Careful work.

Half the people who ring me have already been quoted twice. Sometimes for a job that didn't need doing. Sometimes for two grand more than it should cost. Most often by an engineer who left the kitchen looking like a building site afterwards.

Coastal Forge is just me. I quote the same price whether you've had ten estimates or none, I turn up at the time we agreed, and the pipework I leave behind is the only kind I'm prepared to put my name on. Tidy, logical, not too proud to be photographed.

Pipework you wouldn't mind on show.

Ten recent jobs, photographed at the moment I packed the van up. No staging, no retouching. Whitby, Sandsend and the moor villages.

Services

Six services. None subcontracted.

No apprentices learning on your boiler. Same engineer from the first phone call to the final certificate, and a quote that doesn't change between the visit and the invoice.

01Service

Boiler installation

New combis, system swaps and regular replacements. Supplied with a manufacturer warranty, fitted with a magnetic filter as standard, and the pipework run cleanly enough to leave the cupboard door open.

  • Manufacturer warranty
  • Magnetic filter standard
  • Tidy pipework
02Service

Servicing & repairs

Yearly services to keep the warranty valid, breakdown call-outs when it's already gone wrong, and an honest diagnosis when you've been told you need a whole new unit when you don't.

  • Annual service
  • Breakdown call-out
  • Second-opinion quotes
03Service

Hot water cylinders

Unvented Megaflo installs, vented cylinder replacements and pressure cylinders for new-build properties. G3 qualified, fully insured, all expansion vessels signed off.

  • G3 qualified
  • Megaflo specialist
  • Pressure cylinders
04Service

Radiators & heating upgrades

Replace one rad or refit the whole system. Vertical columns, designer panels, low-surface-temp units for kids' rooms. Pipework re-run before you tile, plastered around afterwards.

  • Designer rads
  • TRV swaps
  • Power flush
05Service

Plumbing & gas works

Gas cookers and hobs, range-cooker swaps, leak isolations, mains-pressure tap upgrades, anywhere a brass valve or copper run needs to go in. Certified, signed off, photographed for the records.

  • Gas appliances
  • Pipework runs
  • Leak repairs
06Service

Emergency call-outs

Heating gone on the school run? No hot water on a Sunday? Sam picks up and books you in for the same day where the diary allows. No emergency surcharge, no clock-watching.

About Sam

One number.
One van.
One face.

Sam Ellis. Director, only engineer, and the person who picks up the phone at Coastal Forge Gas & Heating Ltd. The number you ring is mine, the van you see pulling up is mine, and the price I quoted on the phone is the price on the invoice.

Patch is Whitby out to Staithes one way and Robin Hood's Bay the other, plus the moor villages in between. I work around your day, not mine. If the heating drops on a Saturday morning, I'll likely still answer.

Five stars on every one.

Sample reviews — placeholder text

Two of us work nights, so booking a tradesman has always been a faff. Sam offered to start at seven in the morning before our shifts, did the boiler swap and the radiator fittings in two visits, and asked roughly half what the other engineers had quoted. He's the one we ring now for anything plumbing-related.

Anthracite vertical designer radiator install
From the install gallery
Two new column rads, house warm again by lunchtime.

Booked in for a Saturday, finished by lunchtime. Reasonable price too.

Margaret Hartley
January 2026

Polite, knowledgeable, and the install looks neater than the rest of our kitchen.

Daniel Pearce
March 2026

Replaced the loft tank setup with a single combi. Three days, no mess.

Several jobs over the years. Wouldn't bother ringing anyone else now.

Where we work

Coast and moors,
from the workshop.

Workshop near Whitby Marina. Most call-outs are inside YO21 and YO22, with the moor villages reached daily on the way through. Outside that strip, ring anyway. The van travels.
